A number of years in the past, my psychologist and I mentioned my worry of world warming and the top of the world.

He defined that certain, I might give attention to that, and that he was most likely proper about what was going to occur, however that it wasn’t a wise solution to stay my life. No, she stated, true knowledge comes from with the ability to put apart the large image and discover happiness. Love your youngsters and your partner. To take pleasure in meal now and again. To attempt to discover achievement in your work and satisfaction in your hobbies. Maybe you will discover consolation in a being better than your self.

He was proper 20 years in the past, in a approach. I imply, attaining denial and tolerating cognitive dissonance has helped me cope with the melancholy that has haunted me my complete life.

In fact, because the folks of the UK are experiencing in the present day and tomorrow, she was equally incorrect. I’ve written about local weather change. I’ve edited a thousand tales about him. I’ve had a Tesla. And, in actuality, I don’t take duty for the best menace that exists to civilization.

After I can now not block out the truth of my ideas and have a look at my 8-year-old son, I’m overwhelmed with disappointment for the world I’m abandoning. I’m elevating him as I used to be raised, as if the longer term is a straight line and the trail ahead solely results in progress.

However I do know higher.

There’s a widespread perception that the media is about dramatic headlines and scaremongering. I can let you know from the within that though the headlines typically exaggerate the reality, particularly if we’re not speaking about foxnews and different Murdoch retailers, the alternative is true.

For a few years, senior editors tended to downplay local weather change tales, each due to a way that duty means underestimation, and due to their dedication to the precept of either side. I had greater than 20 years in my profession earlier than The New York Instances or The Related Press have been keen to name world warming for what it’s and cease giving deniers the identical house. In some way, with the planet on hearth, my colleagues have been capable of finding”superb folks, on either sideas former president donald trump stated about neo-Nazis and everybody else.

There’s additionally a sense that, with the readership shrinking and the viewers fragmented, it is necessary to not alienate folks. “Republicans additionally purchase tennis“, like the good Michael Jordan stated.

It will be important that we notice that local weather change doesn’t have two sides and, regardless of the cheerful headlines about carbon seize and electrical autos, we’ll miss all of the objectives that he United Nations established to maintain the rise in temperatures on Earth beneath 1.5 levels Celsius. The warming is more likely to be two or three levels, or extra, earlier than the top of this century.

Has been efforts to visualise what that hotter planet would seem like. We throw the phrase catastrophic. Click on on the hyperlink to see what it actually means.

The worldwide goals have been set at halve the quantity of carbon launched into the environment by 2030. This won’t occur. It will possibly’t occur. And it is time to acknowledge that reality. The one main contributor to a discount within the technology of greenhouse gases it was a plague, and even that did not do a lot.

to satisfy the UN local weather objectives – that are fairly modest – we might have wanted greater than Democratic Senator Joe Manchin vote even for plus modest motion.

We have to face the info. Nobody in authorities is even considering of dreaming of proposing a coverage that really curbs world warming. The truth is, because the struggle in Ukraine rages on, the federal government’s solely focus is to decrease gasoline costs and enhance provides of the very drug that’s killing us.

Folks and birds are dropping lifeless from the warmth. now, not sooner or later. The planet is actually burning now, not sooner or later. the Amazon rain forest name lungs of the planetit’s being felled at such a fee that we’ll see the final tree fall in our lives.

I really like science fiction, actually, however I had not imagined that I’d stay by means of the apocalypse of Soylent Inexperienced. I additionally did not suppose that the folks I’d be apocalypse with would cowl their ears whereas yelling “Lalalalala!”

So what do I’ve to give you, apart from despair?

If you’re an inventor, invent.

If you’re an individual who prays, pray.

If you’re an individual who feels that he can flip the world into compost for redemption, go for it.

For those who’re a pacesetter, for God’s sake, lead.

Star Wars Extended Universe
By way of Disney/Lucasfilm, artwork by Jason Palmer

We dwell within the period of the Expanded Cinematic and Tv Universes: star wars, marvel, DC, Sport of ThronesIt looks like each main franchise goes for as huge a attain as doable, as many exhibits, and as a lot intertextuality as doable. And whereas it has opened up an entire new world of storytelling potentialities, there are additionally a rising variety of main drawbacks.

Add as a substitute of develop

The cast of Once Upon a Time and the characters of Frozen
By way of ABC/Disney

One factor many of those exhibits select to do is add to their ever-expanding roster of characters in favor of constructing on the characters they have already got. As soon as upon a time it rapidly went from an exploration of fairy story characters (together with some non-Disney ones) to the limitless parade of Disney cameos, which have been gone as quick as they have been launched. The complete present was placed on hiatus for half a season to adapt its personal dwell motion. frozen 2 which preceded the precise sequel by a number of years.

They will additionally introduce characters which are fascinating and will be added to the present solid in new methods, simply to these characters to be killed off to supply “stakes” whereas leaning again to maintain the principle solid safe. Seasons 3 and 4 of Unusual issues it killed off a lot of the new characters launched whereas virtually resurrecting Hopper, resulting in a way that the present lacks the power to decide to placing beloved characters in hurt’s method.

Generally a present or film can have the chance to broaden its world or characters in spin-off exhibits or books. Nevertheless, that may change into an issue when the principle/continuity present ignores or contradicts that spin-off.

Unusual issues he had a number of books that defined what occurred to the opposite youngsters within the Hawkins lab. However Season 4 ignored these books, ditching the spin-off tales of the opposite youngsters from Hawkins’ lab, and as a substitute killed most of them within the 001 bloodbath.

That leaves some followers questioning why they put the money and time into pursuing these spin-offs if the creators will ignore them.

The other drawback additionally arises when a franchise turns into too depending on its spin-offs or sprawling supplies.

followers of the mandalorian can be pressured to look at boba fett guide to meet up with Din Djarin and Grogu, who’ve reunited earlier than the present’s third season.

skywalker rise selected to not clarify the return of Palpatine or Rey’s household within the movie and as a substitute used these expanded supplies and even a Fortnite crossover to elucidate issues that the film ought to have taken the time to elucidate.

George RR Martin and HBO grew to become so targeted on the thought of ​​spin-offs that they uncared for the principle franchise and will have soured the model completely.

I actually cannot think about making an attempt to see one thing new from the Marvel Cinematic Universe with out having seen over 14 years of Great films and, more and more, the Great films which have come earlier than or after (ought to Sam Rami? Spiderman films, mark webb Superb Spider-Man films, and the X Males will the flicks be thought of a part of the MCU now?).

Packages that do it properly

That is to not say there have not been films/exhibits that do it properly.

Higher name Saul it managed to interrupt the curse of each the spin-off and the prequel as a result of it would not concentrate on the principle characters of the unique present (whose tales have already been informed) and is dedicated to the scope of the story it is telling. It introduces new characters, but additionally develops new and acquainted characters. It helps that this system took its time and was a lot slower. He knew he had an viewers, however he was assured that the viewers would favor substance to fanservice spectacle.

angel cast
By way of The WB

Angel additionally managed to do that by specializing in comparatively completely different themes and struggles than its ‘mother or father’ present, buffy the vampire slayer (Nerd’s Ardour describes leukocyte as if it have been to develop whereas Angel it is about maturity) and when the exhibits did cross over, it was often restricted to 1 or two episodes, with the scant background supplied permitting informal viewers to grasp the which means and reward viewers of each exhibits. One of the best use of this crossover is the “Idiot for Love”/”Darla” ‘crossover’ which makes use of ‘Rashomon’ model modifying to point out the identical occasions from two completely different views (Spike and Darla), which additionally permits viewers informal simply perceive .

Ghostface wielding a knife in Scream (2022)
By way of Paramount

Scream (2022) is one other robust instance of this, deliberately commenting on the development of ‘re-quels’ making an attempt to attraction to followers each outdated and new by making the media Easter Egg nostalgia fests pretending to be remakes of classics. Whereas it would not name itself ‘Scream 5,’ it continues the story longtime followers have been following for 26 years, whereas additionally making the story accessible to newcomers.

And in conclusion…

I say this as a fan of many of those expanded universes; Love Star Wars, Marvel, DC, and lots of different expanded universe franchises. I would not be writing right here at the moment if it wasn’t for them and the love for them. However I additionally need to see them properly achieved.

As with most issues, writing expanded universes is a balancing act.

Relying too closely on different properties to finish your story can drive off new or informal audiences or create a narrative that does not stand by itself.

Should you fully ignore all expanded supplies, you’ll drive away devoted followers who spend numerous money and time in your work.

Simply because you could have a built-in viewers of followers does not imply it is best to simply cater to them or take them with no consideration.

Margot Robbie and Ella Jay Basco in Birds of Prey: And the Fantabulous Emancipation of One Harley Quinn (2020)
By way of Warner Bros/DC Leisure

My greatest recommendation is to slender the main target. DC Leisure has realized that as a substitute of copying the sprawling Marvel Cinematic Universe, they’ll make a bunch of distinctive films, permitting a variety of tones, characters, and administrators the chance to discover the inflexible continuity of the Marvel Cinematic Universe. Great I may by no means permit. Even then, most of the greatest tales in these expanded universes are tales that concentrate on one story and discover methods to naturally weave within the tales of others. The story of a helmeted warrior who adopts a magical alien baby. A narrative of a Pakistani-American superhero fangirl who will get her personal powers from her.

Generally smaller is healthier.

With the discharge of The primary pictures from the James Webb Area Telescope on July 12. (Y a sneaky revelation from US President Joe Biden on July 11), NASA, ESA and the Canadian Area Company proved that the two-decade-long, $10 billion dream viewer 1 million miles from Earth actually works. And works impeccably simply take a take a look at the improved pictures that Webb delivered in comparison with its predecessor, Hubble. They’re visceral masterpieces that drive us to consider the magnificence of the universe and replicate on the insignificant nook of our photo voltaic system.

However what we noticed in early July was simply the preface to the JWST e-book. It is going to be the chapters that observe that can write his legacy.

Whereas the telescope’s first full-color outcomes have been glorious, they’re only a style of the instrument’s capabilities. In fact, we might not even have phrases to explain what’s to come back, in the best way that the Hubble Area Telescope’s first mild picture didn’t foreshadow the wonderful deep fields that may someday plaster the partitions of the astronomy division or the nebulae that may encourage poetry.

5 galaxies engaged in a dance make up Stephan’s Quintet. JWST pictures launched on July 12, 2022.

However we’d have the ability to infer some scenes from the way forward for JWST as a result of, regardless of the publicity of this telescope, scientists have been lining up for years to make use of it.

Researchers at the moment are able to level to phenomena that can blow your thoughts: huge black holes, shattered galaxy mergers, luminescent binary stars emitting smoke indicators, and even wonders nearer to house like Ganymede, an icy moon of Jupiter.

Extra particularly, a number of fortunate early scientists have proposals divided into six classes, every meticulously chosen by the James Webb Area Telescope Advisory Committee and the Area Telescope Science Institute in November 2017, to not point out the greater than 200 separate worldwide tasks . time allotted on the telescope and those that are prepared to affix the ready checklist.

However the preliminary cadre of JWST area explorers is certain to be helpful to each the scientist and the scope. These research will create information units, baselines, useful life hacks, and usually put together the highly effective machine instruments for all the pieces that comes subsequent. For the nice moments that can go down in historical past.

“To appreciate the total scientific potential of the James Webb Area Telescope, it’s crucial that the scientific group rapidly study to make use of its devices and capabilities,” reads a web page about Director’s Early Exit Discretionary Science Applicationswhich was drawn as much as choose which researchers will take a look at JWST throughout its first 5 months of science operations (after the 6-month telescope start-up interval).

Perusing the checklist has raised my anticipation, and I guess it would elevate yours too.

Here’s a snippet.

Turning the web page for JWST

About 3.5 billion light-years from Earth is a big cluster of galaxies known as Abell 2744, also called the Pandora Cluster.

You possibly can say that is the Good preliminary candidate for JWST, as it’s a part of the traditional and distant universe. NASA’s next-generation telescope comprises a bunch of infrared imaging tools that may entry mild emanating from the distant cosmos — mild that neither human eyes nor commonplace optical telescopes can see. It’s a mixture of scientific exploration executed within the sky.

Thus, a workforce of researchers plans to look at what is going on on this vivid cluster of galaxies, hidden from human sight however very important to astrophysical development.

Abell 2744, imaged by combining X-rays from Chandra (diffuse blue emission) with optical mild information from Hubble (pink, inexperienced, and blue).

NASA/CXC; Optics: NASA/STScI

They plan to make use of two of JWST Devicesknown as near-infrared spectrograph and near-infrared imager and slitless spectrograph, which may merely decode the chemical composition of distant worlds trapped within the infrared zone that we will not get previous.

However JWST is just not merely farsighted. You can even flip in your studying glasses to scan issues close by.

That is why one other workforce is extra all in favour of determining find out how to navigate phenomena in our personal cosmic neighborhood. Their blueprints say they may characterize the cloud layers, winds, composition, temperature construction, and even exercise of Jupiter’s auroras, also called the Jovian model of our Northern Lights.

This analysis bit is able to use virtually all people of JWST’s revolutionary infrared tools: Nirspec, Niriss, in addition to the JWST Close to-Infrared Digicam, Alpha Imager, and Mid-Infrared Digicam (MIRI), which, as you may guess, focuses on detecting mid infrared mild. “Our program will show the capabilities of JWST’s devices on one of many largest and brightest sources within the photo voltaic system and on very faint targets subsequent to it.” write in your summary.

A number of the work on Jupiter has already been executed based on the venture standing report and observing home windows proceed via August. As well as, Jupiter’s moon Ganymede, which is the most important within the photo voltaic system, and the extraordinarily lively Io will even be examined with MIRI. The latter is especially fascinating, because the researchers I hope to resolve the volcanoes of Io and examine Webb’s views with the classical views.

Jupiter, middle, and its moon Europa, left, are seen via the two.12-micron filter of the James Webb Area Telescope’s NIRCam instrument.

NASA, ESA, CSA and B. Holler and J. Stansberry (STScI)

The subsequent step is dust-focused scientists. However not simply any powder. Star mud.

We all know that mud is the principle ingredient within the formation of stars and planets that embellish our universe, however we’re nonetheless confused in regards to the timeline that adopted to get us to the place we’re in the present day, particularly since a lot of it, essential for our -the mud of existence is scattered all through the early universe. And the early universe is illuminated solely by infrared mild.

AHA. Exactly what JWST can (and can) delve into.

Breaking down the historical past of stardust means constructing an understanding of the constructing blocks of our cosmic universe — much like how the examine of atoms opens up data about bits of matter. And as Carl Sagan as soon as stated: “The cosmos is inside us. We’re product of star stuff. We’re a approach the universe is aware of itself.”

Maybe JWST may help the universe in its quest for perception.

Simply wait till JWST sees this

Over the previous couple of months basically, as a science author, I’ve witnessed the repetition of a tremendous feeling. “Simply wait till the James Webb Area Telescope sees this.”

Not in these phrases, precisely, however undoubtedly in that tone.

In April, for instance, the Hubble Area Telescope reached a document milestone when it delivered a picture of the farthest star now we have ever seen from the distant universe. A star magnificence named Earendelwhich aptly interprets to “morning star” in Previous English.

“Finding out Earendel will probably be a window into an period of the universe which we aren’t aware of, however which led to all the pieces we all know,” Brian Welch, one of many discovering astronomers at Johns Hopkins College, stated in a press release.

stsci-01fws4xz7qt98wrwsztg9e86zx

Earendel (indicated by an arrow) is positioned alongside a ripple in space-time that provides him excessive magnification, permitting him to emerge into view from his host galaxy, showing as a pink smudge within the sky.

However keep in mind how JWST is armed to review the traditional and unseen universe? Precisely. The examine authors are ready to take a look at Earendel via JWST’s lens, hopefully confirming whether or not it truly is only a stellar physique and quantifying what sort of dawn star it’s.

JWST may additionally clear up a mysterious puzzle posed by Neptune, our photo voltaic system’s gaseous blue topper: it is getting colder for no obvious cause. However “the beautiful sensitivity of the area telescope’s mid-infrared instrument, MIRI, will present unprecedented new maps of the chemistry and temperatures in Neptune’s environment,” stated Leigh Fletcher, co-author of a examine on the thriller and planetary scientist on the College. leicester, stated in a press release.

There’s additionally the intrigue of deciphering the majestic majesties of our cosmic realm: supermassive black holes, and even an odd billion-year-old ancestor of black holes.

“Webb may have the ability to decisively decide how widespread these fast-growing black holes actually are,” Seiji Fujimoto, one of many discovering astronomers on the Niels Bohr Institute on the College of Copenhagen, stated in a press release.

Hubble and James Webb Area Telescope Picture Comparability: See the Distinction

See all photographs

And eventually, I might say that essentially the most wonderful facet of JWST, not less than to me, is that it’s at the moment the most effective likelihood now we have to seek out proof of extraterrestrial life. aliens

Some scientists are even prematurely warning in opposition to false positives of natural matter that the JWST software program may choose up, in order to not alarm most of the people (me) when that day comes. But when that day comes, our jaws will little question drop to the bottom and our coronary heart price will quicken, unequivocally relating to July 12 as a faint reminiscence.

And even when that day would not come, it will not be lengthy earlier than NASA’s new muse of area exploration sends again a picture as gorgeous as Hubble’s first. deep subject in 1995 – one which we can not but comprehend.

BiFan 2022 Review: MIND UNIVERSE, SF Indie Explore Ideas Of Grief And Memory

Given the more and more democratic entry to movie expertise and the explosion of field workplace, scores and broadcast success of style tales within the Korean market, it’s not stunning {that a} rising variety of native filmmakers have embraced science fiction. , a style that enables storytellers to search out new methods to precise previous concepts. Nevertheless, the style remains to be in its infancy within the nation and has had a patchy observe file.

the Apostle Supervisor Kim Jin-moo takes his hit at bat with Universe of the thoughtsa movie that brings collectively two very complementary science fiction medium-length movies in a single characteristic movie that explores the implications of utilizing expertise to ease our ache when the individuals we love go away us.

In ‘Right now of Tomorrow’, the aged Heejin has subscribed to a service the place she will be able to log right into a digital reconstruction of her late associate Seonwoo’s consciousness. On this digital world, she reverts to being a younger woman and each time the simulation begins, she seems on a seashore, with Seonwoo just a few steps away looking to sea.

The issue is that Seonwoo would not acknowledge her and all she has is three hours to speak to him earlier than the present ends and Seonwoo’s recollections are as soon as once more erased. Heejin can re-enter this system each 24 hours. Heejin retains making an attempt to get Seonwoo to recollect her, however every little thing she makes of her fails to jog her reminiscence. Finally she tries one thing completely different. She pretends to not know him.

In ‘Our Universe’, astronaut Sori travels the galaxy sooner or later when she receives the information of her father’s loss of life. Her father is composer Kim Hyung-suk (a real-life determine who composed the rating for my cheeky womanamongst others, who performs himself right here) and the digital funeral has already begun.

Hyung-suk’s conscience bought on the funeral present and chats with mourners by way of varied video chat rooms. Unable to confront him straight, Sori hides in a number of rooms, by way of which we get a glimpse into Hyung-suk’s life, as she shares his final phrases together with her college students, trainees, and his household. Witnessing these different interactions, Sori always summons the braveness to talk together with her beloved father one final time.

Whereas Korea has but to supply a lot of science fiction works, tales coping with reminiscence and grief make up for a big portion of it. Amongst these are tales that think about the usage of synthetic intelligence or cloning expertise to deliver family members again to life, similar to within the acclaimed American unbiased movie. marjorie first. Korean examples embrace Lee Yong-ju’s action-SF seobokLee Ho-jae TV film goodbye my life insurance coverage and Kim Tae-yong’s subsequent star-studded venture Wonderlandwhich is able to premiere on Netflix.

Whereas sci-fi remains to be a little bit of an unknown within the nation, melodrama is the trade’s staple food regimen and it is smart that native storytellers would use it as a place to begin for their very own variations of sci-fi.

Universe of the thoughts he is earnest and honest, however he is additionally simplistic and typically overly cloying in his makes an attempt to promote his feelings. Typically much less is extra, and that is very true of high-concept works that should interact in a cautious balancing act of tone and magnificence. Whereas fantasy could be forgiving, science fiction tales that posit concepts about future expertise interacting with our society threat credibility if they do not appear grounded.

Since Kim’s movie consists of two full and comparatively brief tales, the tales she tells by no means lose their welcome. Universe of the thoughts it is a casually humorous and mildly thought-provoking have a look at the place our expertise may take us, however because of the limitations of its construction, it solely scratches the floor of its personal concepts.

CDevelopment has been accomplished on what’s described as the biggest municipal solar energy facility in Westchester County. The system is distributed throughout 9 city-owned websites in White Plains. It’s designed to supply 8,100 megawatt hours of electrical energy every year. A megawatt hour is a million watts of electrical energy produced over a one hour interval. A million watts is sufficient to energy greater than 9,000 normal 100-watt gentle bulbs on a 110-volt system.

The system was constructed by Schenectady-based Distributed Photo voltaic Improvement (DSD), which the town chosen after sending out a Request for Proposals (RFP) to about 100 photo voltaic contractors. The RFP was ready by the Metropolis’s Division of Public Works (DPW) with the cooperation of the New York Energy Authority (NYPA), which has its administrative places of work in White Plains. The town’s DPW commissioner on the time, Rick Hope, described DSD as a “spin-off” from GE Photo voltaic.

The town says the quantity of electrical energy to be generated is sufficient to energy greater than 700 houses every year.

The 9 photo voltaic tasks embrace a mix of rooftop, rooftop and floor installations at 4 parking heaps, the Ebersole Ice Skating Rink, the Gedney Method Recycling Yard, Gillie Park, the Metropolis Water Division and the DPW web site. of Brockway Place.

When the challenge was beginning, White Plains Mayor Tom Roach informed Enterprise Journals that the town will obtain about $1 million a yr in income from leasing the areas occupied by the photo voltaic websites and may have no prices related to them.

Upon completion of building, Roach mentioned: “We’re in a local weather disaster and we’re compelled to acknowledge the urgency and take deliberate motion to construct a sustainable and resilient planet. The Metropolis of White Plains will proceed to function a pacesetter in sustainability by investing in and implementing renewable vitality initiatives that may considerably scale back greenhouse fuel emissions.”

Justin E. Driscoll, Interim President and CEO of NYPA, mentioned, “The New York Energy Authority is happy to have performed a key position in serving to the Metropolis of White Plains create an expansive and distinctive portfolio of photo voltaic and energy programs. storage amenities that supply renewable vitality. to cut back the area’s carbon footprint. Because the business middle of Westchester County, White Plains is setting an instance for different communities seeking to develop different clear vitality choices. Hopefully, different municipalities will observe go well with and assist our state transfer even additional towards its daring local weather motion targets.”

David Eisenbud, senior director of organizing at DSD, famous that two-thirds of White Plains websites include floor and garage-top parking cover programs.

“It is a specialised utility that DSD has pioneered,” Eisenbud mentioned. “It will assist remodel the town. DSD doubled the anticipated capability within the metropolis’s parking garages due to our distinctive photo voltaic cover designs.”

He mentioned the canopies over the parking areas will do extra than simply present a platform for the photo voltaic panels; they are going to defend folks and autos from rain and snow whereas enhancing the middle expertise for guests.

After finishing the challenge, Eisenbud mentioned, “This distinctive portfolio positions the town as a pacesetter in photo voltaic vitality adoption and exhibits different communities what is feasible in the case of clear vitality.”

A few of the photo voltaic installations included infrastructure enhancements, reminiscent of a brand new roof for the Ebersole ice rink and a storage space for the water division. Canopies at among the websites function a proprietary built-in water administration system to handle runoff water from rain and snow soften. The photo voltaic subject on the Gedney Recycling Plant options the primary floating basis cover mounted on the lid of a landfill. Moreover, two on-site cover programs incorporate sidewalls to retailer and defend metropolis tools. In building, a floating basis doesn’t use footings. It’s a slab with edges that go just under the frost line. This kind of basis can transfer as temperatures trigger the soil to compact and broaden.

Metropolis and DSD officers mentioned they hope the photo voltaic system won’t solely scale back reliance on fossil fuels for electrical energy technology, but in addition produce environmental advantages equal to taking some 1,300 vehicles off the street or planting 101,000 new bushes. in White Plains.

Mapping Earth’s dust

Developed by NASA’s Jet Propulsion Laboratory in Southern California, the Earth Surface Mineral Dust Source Investigation (EMIT) employs NASA imaging spectroscopy technology to measure the mineral composition of dust in Earth’s arid regions. Mineral dust blown into the air can travel significant distances and affect Earth’s climate, weather, vegetation, and more. For instance, an area may be warmed by dust made of dark minerals that absorb sunlight, whereas a region might be cooled by dust made of light-colored minerals. Air quality, surface conditions including the speed at which snow melts, and ocean phytoplankton health are all impacted by blowing dust. For the duration of a year, the investigation will collect images to generate maps of the mineral composition in the dust-producing regions on Earth. Such mapping could advance our understanding of how mineral dust affects human populations now and in the future.

Speedier immune system aging

Immunosenescence is the changes in the immune system due to aging. Microgravity causes changes in human immune cells that resemble immunosenescence, but they happen much faster than the actual process of aging on Earth. Sponsored by ISS National Lab, the Immunosenescence investigation, uses tissue chips to study how microgravity affects immune function during flight and whether immune cells recover post-flight. Tissue chips are small devices that contain human cells in a 3D structure, that allow researchers to test how those cells respond to stresses, drugs, and genetic changes.

“Immune aging impacts tissue stem cells and their ability to repair tissues and organs,” says principal investigator Sonja Schrepfer, professor of surgery at University of California San Francisco (UCSF). “Our studies aim to understand critical pathways to prevent and to reverse aging of immune cells.”

“Spaceflight conditions enable the study of immune aging that would not be feasible in the lab,” says co-investigator Tobias Deuse, professor of surgery at UCSF. This work could support development of treatments for immune system aging on Earth. The investigation also could support development of methods to protect astronauts during future long-duration spaceflight.

Soil in space

Complex communities of microorganisms carry out key functions in soil on Earth, including supporting plant growth and cycling of carbon and other nutrients. DynaMoS, an investigation sponsored by NASA’s Division of Biological and Physical Sciences (BPS), examines how microgravity affects metabolic interactions in communities of soil microbes. This research focuses on microbe communities that decompose chitin, a natural carbon polymer on Earth.

“Soil microorganisms carry out beneficial functions that are essential for life on our planet,” says principal investigator Janet K. Jansson, chief scientist and laboratory fellow at Pacific Northwest National Laboratory. “To harness these beneficial activities for future space missions, we need to understand more about how conditions in space, like microgravity and radiation, influence these microbes and the beneficial functions that they provide. Perhaps in the future, we will use beneficial soil microbes to enhance growth of crops on the lunar surface.”

Improved understanding of the function of soil microorganism communities also could reveal ways to optimize these communities to support agricultural production on Earth.

Genes, no cells

Cell-free technology is a platform for producing protein without specialized equipment of living cells that need to be cultured. Genes in Space-9, sponsored by the ISS National Lab, demonstrates cell-free production of protein in microgravity and evaluates two cell-free biosensors that can detect specific target molecules. This technology could provide a simple, portable, and low-cost tool for medical diagnostics, on-demand production of medicine and vaccines, and environmental monitoring on future space missions.

“Biosensors are a class of synthetic biology tools with immense potential for spaceflight applications in contaminant detection, environmental monitoring, and point-of-care diagnostics,” said Selin Kocalar, student winner of Genes in Space 2021. “This investigation seeks to validate their use aboard the space station. If it is successful, Genes in Space-9 will lay the foundation for downstream applications of biosensors for space exploration and resource-limited settings on Earth.”

Genes in Space, an annual research competition, challenges students in grades 7 through 12 to design CRISPR technology in microgravity in 2019.

Better concrete

Biopolymer Research for In-Situ Capabilities looks at how microgravity affects the process of creating a concrete alternative made with an organic material and on-site materials such as lunar or Martian dust, known as a biopolymer soil composite (BPC). Using resources available where construction takes place makes it possible to increase the mass of the construction material and, therefore, the amount of shielding.

“Astronauts on the Moon and

BPCs also could offer an environmentally friendly concrete alternative for making structures on Earth. In 2018, concrete production represented 8% of global carbon emissions. BPC material has zero carbon emissions and can be made from local, readily available resources, which also simplifies supply chains. This experiment is a part of NASA’s Student Payload Opportunity with Citizen Science (SPOCS) program, which provides students enrolled in institutions of higher learning the opportunity to design and build an experiment to fly to and return from the International Space Station.

These are just a few of the hundreds of investigations currently being conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars through NASA’s Artemis program.

The birthplace of golf faces a risky future on a warming planet https://dndrx.com/the-birthplace-of-golf-faces-a-risky-future-on-a-warming-planet/ https://dndrx.com/the-birthplace-of-golf-faces-a-risky-future-on-a-warming-planet/#respond Sun, 17 Jul 2022 05:02:47 +0000 https://dndrx.com/the-birthplace-of-golf-faces-a-risky-future-on-a-warming-planet/ Read more]]>

ST. ANDREWS, Scotland – It is the uncommon golfer who would not fear concerning the climate ruining a spherical or depriving pictures from distance.

However alongside the North Sea on a windswept fringe of Scotland, heralded for hundreds of years because the birthplace of golf, greenskeepers of this period concern a a lot bleaker prognosis. In that nightmare, what they name an ideal storm would hit, hitting at excessive tide and pushing an easterly wind, possible accelerating coastal erosion.

“12 months after 12 months, we’re apprehensive,” stated David Brown, common supervisor of the 460-year-old Montrose Golf Hyperlinks.

“You are preventing the unknown, actually,” he stated. “We may go the subsequent 10 years with out that excellent storm, after which fairly simply in a single winter we may have that excellent storm thrice. After which, how a lot land will we lose?

Montrose, which the federal government estimates has misplaced tens of meters of shoreline in current a long time, is believed to be among the many most threatened of Scotland’s roughly 600 fields, greater than 1 in 6 of that are coastal. Nonetheless, in an indication of how world status can provide solely a restrict to security, researchers imagine St. Andrews, residence to the world’s oldest course and host of the one hundred and fiftieth British Open, faces a heightened menace of flooding. inside. 30 years

Scientists do not suppose the Previous Course will likely be completely underwater any time quickly, with the Street Gap being swallowed up endlessly by the ocean. However golf has had no selection however to start to weigh its position in local weather change, not least by the sprawling, lush, thirsty programs that typically change timber after which require fertilizer and garden mowing, whereas questioning the right way to protect the fairways and surrounding greens. the world.

Scotland’s longstanding embrace of golf as a cultural and financial large makes the problem of explicit urgency on this area, the place the Open is scheduled to conclude on Sunday. At St. Andrews Hyperlinks alone, six public programs, together with the Previous Course, collectively host some 230,000 rounds a 12 months close to West Sands, only a quick stroll from a few of the world’s most revered holes. (A seventh St. Andrews Hyperlinks course, which opened in 2008, is positioned elsewhere within the space.)

Programs within the east of Scotland, which have low-lying sediments that may be simply eroded, are usually thought to face extra imminent hazard than these on the west coast, the place the geology is much less susceptible to the results of local weather change.

However the solutions have gotten widespread.

Royal Dornoch, a beloved course within the north of Scotland, has been attempting to revive the lavatory that had eroded and threatened a fairway. Lundin, about half an hour’s drive from St Andrews, added ÂŁ100,000 value of fencing to protect towards erosion, and the R&A, the organizer of the Open, has earmarked a whole lot of hundreds of kilos for grants to “develop options”.

There could also be limits to what programs can do, nonetheless your choices are typically narrowed down by cash, location, severity of menace, or penalties of motion in an space. Some folks fear that sources that is likely to be accessible in a spot just like the Previous Course, wealthy in historical past and worldwide significance, is probably not as accessible elsewhere.

“There are fears about golf programs, however we are going to assist shield golf programs if we do the best issues to guard the setting and mitigate and adapt to the consequences of local weather change,” Scotland’s First Minister Nicola Sturgeon stated in an interview. by the ocean. Friday. “There may be loads of work that we’re doing in Scotland to do this. It’s about extra than simply defending golf programs, however there isn’t a doubt that in locations like this it is usually a key half.

“The local weather is altering, however in Scotland we’re actually specializing in ensuring we shield what issues most to us as we face these challenges. And it’s extremely apparent throughout this week of the 12 months, particularly, how a lot Scotland cares about golf.”Some consultants, together with Professor Invoice Austin of the College of St. Andrews, hope {that a} rising variety of engineered options will likely be put in place through the years, balanced with extra pure options that may contain permitting the ocean to slip inside in a managed method.

One of many lingering questions, nonetheless, is whether or not these efforts will come to fruition shortly sufficient.

At Montrose, Brown runs a course that has been within the makeshift enterprise recently, willingly and never: tees have been misplaced, holes have been shortened and rerouted, and fairways have been reseeded. Nonetheless, there is not some huge cash to go round, and weather-related modifications eat up a few third of the course’s inexperienced finances.

“With out authorities safety, we may see 50 years of golf comfortably performed, or the proper storm two or thrice in a winter, 10 years,” he stated.

Considerations round St. Andrews will not be that severe but, however they’re rising. In an particularly bleak state of affairs outlined final 12 months in a Scottish authorities venture report, a part of the West Sands may draw round 820 yards to hyperlinks by 2100 if there are excessive emissions and a “do nothing” method to managing the coast.

“I am positive a two hundredth Open will likely be performed on one thing that appears quite a bit just like the Previous Course immediately, however there could also be some engineering behind the scenes,” Austin stated.

Past that, nonetheless, his prognosis is extra horrifying.

“When you ask me about 300, then I’d say the Previous Course can have moved,” he stated, “however there’ll nonetheless be one thing in St. Andrews that has the texture and, I feel, legacy of the Previous Course. .”

Solar system orbit circles illustration

New Caltech analysis proposes a brand new answer to a long-standing thriller concerning the skinny disks of fuel that swirl round younger stars.

The important thing to fixing a long-standing thriller concerning the skinny disks of fuel that swirl round younger stars: the motion of a small variety of charged particles. That is in line with a brand new research from the California Institute of Know-how (Caltech).

These spinning disks of fuel, referred to as accretion disks, final for tens of hundreds of thousands of years and are an early stage within the evolution of the photo voltaic system. They comprise a small fraction of the mass of the star round which they revolve; think about a[{” attribute=””>Saturn-like ring as big as the solar system. They are called accretion disks because the gas in these disks spirals slowly inward toward the star.

Astrophysicists recognized long ago that when this inward spiraling transpires, it should cause the radially inner part of the disk to spin increasingly faster, according to the law of the conservation of angular momentum. To understand the basic idea of the conservation of angular momentum, think of spinning figure skaters: when their arms are outstretched, they spin slowly, but as they draw their arms in, they spin faster and faster.

The law of angular momentum conservation states that the angular momentum in a system stays constant, and angular momentum is proportional to velocity times radius. Therefore, if the skater’s radius decreases because they have pulled their arms in, then the only way to keep angular momentum constant is to increase the spin velocity.

The inward spiral motion of the accretion disk is analogous to a skater drawing their arms in—and as such, the inner part of the accretion disk should spin faster. Astronomical observations do indeed show that the inner part of an accretion disk does spin faster. Curiously, however, it does not spin as fast as predicted by the law of conservation of angular momentum.

Solar System Planets in Orbit

Collisions between neutral atoms and a much smaller number of charged particles may explain why the inner part of the solar system spin faster.

Scientists have investigated many possible explanations for why accretion disk angular momentum is not conserved over the years. Some hypothesized that friction between the inner and outer rotating parts of the accretion disk might slow down the inner region. Calculations, however, demonstrate that accretion disks have very little internal friction. According to the dominant current hypothesis, magnetic fields cause a phenomenon known as a “magnetorotational instability” that results in the production of magnetic turbulence and gas—effectively forming friction that slows down the rotational speed of inward spiraling gas.

“That concerned me,” says Paul Bellan, professor of applied physics at Caltech. “People always want to blame turbulence for phenomena they do not understand. There’s a big cottage industry right now arguing that turbulence accounts for getting rid of angular momentum in accretion disks.”

A decade and a half ago, Bellan began investigating the question by analyzing the trajectories of individual atoms, electrons, and ions in the gas that constitutes an accretion disk. His goal was to determine how the individual particles in the gas behave when they collide with each other, as well as how they move in between collisions, to see if angular momentum loss could be explained without invoking turbulence.

As he explained over the years in a series of papers and lectures that were focused on “first principles”—the fundamental behavior of the constituent parts of accretion disks—charged particles (i.e., electrons and ions) are affected by both gravity and magnetic fields, whereas neutral atoms are only affected by gravity. This difference, he suspected, was key.

Caltech graduate student Yang Zhang attended one of those talks after taking a course in which he learned how to create simulations of molecules as they collide with each other to produce the random distribution of velocities in ordinary gases, such as the air we breathe. “I approached Paul after the talk, we discussed it, and ultimately decided that the simulations might be extended to charged particles colliding with neutral particles in magnetic and gravitational fields,” Zhang says.

Ultimately, Bellan and Zhang created a computer model of a spinning, super-thin, virtual accretion disk. The simulated disk contained around 40,000 neutral and about 1,000 charged particles that could collide with each other, and the model also factored in the effects of both gravity and a magnetic field. “This model had just the right amount of detail to capture all of the essential features,” Bellan says, “because it was large enough to behave just like trillions upon trillions of colliding neutral particles, electrons, and ions orbiting a star in a magnetic field.”

The computer simulation showed collisions between neutral atoms and a much smaller number of charged particles would cause positively charged ions, or cations, to spiral inward toward the center of the disk, while negatively charged particles (electrons) spiral outward toward the edge. Neutral particles, meanwhile, lose angular momentum and, like the positively charged ions, spiral inward to the center.

A careful analysis of the underlying physics at the subatomic level—in particular, the interaction between charged particles and magnetic fields—shows that angular momentum is not conserved in the classical sense, though something called “canonical angular momentum” is indeed conserved.

Canonical angular momentum is the sum of original ordinary angular momentum plus an additional quantity that depends on the charge on a particle and the magnetic field. For neutral particles, there is no difference between ordinary angular momentum and canonical angular momentum, so worrying about canonical angular momentum is unnecessarily complicated. But for charged particles—cations and electrons—the canonical angular momentum is very different from the ordinary angular momentum because the additional magnetic quantity is very large.

Because electrons are negative and cations are positive, the inward motion of ions and outward motion of electrons, which are caused by collisions, increases the canonical angular momentum of both. Neutral particles lose angular momentum as a result of collisions with the charged particles and move inward, which balances out the increase in the charged-particle canonical angular momentum.

It is a small distinction, but makes a huge difference on a solar system-wide scale, says Bellan, who argues that this subtle accounting satisfies the law of conservation of canonical angular momentum for the sum of all particles in the entire disk; only about one in a billion particles needs to be charged to explain the observed loss of angular momentum of the neutral particles.

Furthermore, Bellan says, the inward motion of cations and outward motion of electrons results in the disk becoming something like a gigantic battery with a positive terminal near the disk center and a negative terminal at the disk edge. Such a battery would drive electric currents that flow away from the disk both above and below the plane of the disk. These currents would power astrophysical jets that shoot out from the disk in both directions along the disk axis. Indeed, jets have been observed by astronomers for over a century and are known to be associated with accretion disks, though the force behind them has long been a mystery.
