NASA Taps SpaceX Falcon Heavy Rocket To Launch Jupiter Moon Mission (cnet.com) 44

Jupiter's unusual icy moon Europa may be one of the best spots in the solar system to check for signs of alien life. But first we have to get there. NASA's Europa Clipper spacecraft will get a boost in the right direction from a SpaceX Falcon Heavy, one of the most powerful rockets ever built. From a report: NASA announced Friday that it has selected SpaceX to provide the launch services for the Jupiter moon mission. The launch is scheduled for October 2024 from the Kennedy Space Center in Florida. The contract is worth about $178 million. Europa Clipper will try to determine if the moon could possibly host life. "Key mission objectives are to produce high-resolution images of Europa's surface, determine its composition, look for signs of recent or ongoing geological activity, measure the thickness of the moon's icy shell, search for subsurface lakes, and determine the depth and salinity of Europa's ocean," said NASA. SpaceX has been working with NASA on many fronts, including carrying astronauts to and from the International Space Station, delivering cargo to the ISS and developing a human landing system to return astronauts to the moon through the Artemis program.

Quake-Measuring Device on Mars Gets Detailed Look at Red Planet's Interior (apnews.com) 10

"A quake-measuring device on Mars is providing the first detailed look at the red planet's interior, revealing a surprisingly thin crust and a hot molten core beneath the frigid surface," reports the Associated Press: In a series of articles published this week, scientists reported that the Martian crust is within the thickness range of Earth's. The Martian mantle between the crust and core is roughly half as thick as Earth's. And the Martian core is on the high side of what scientists anticipated, although smaller than the core of our own nearly twice-as-big planet.

These new studies confirm that the Martian core is molten. But more research is needed to know whether Mars has a solid inner core like Earth's, surrounded by a molten outer core, according to the international research teams. Stronger marsquakes could help identify any multiple core layers, scientists said Friday. The findings are based on about 35 marsquakes registered by a French seismometer on NASA's InSight stationary lander, which arrived at Mars in 2018...

InSight has been hit with a power crunch in recent months. Dust covered its solar panels, just as Mars was approaching the farthest point in its orbit around the sun. Flight controllers have boosted power by using the lander's robot arm to release sand into the blowing wind to knock off some of the dust on the panels. The seismometer has continued working, but all other science instruments remain on hiatus because of the power situation — except for a German heat probe was declared dead in January after it failed to burrow more than a couple feet (half a meter) into the planet.

The three studies and a companion article appeared in Thursday's edition of the journal Science.

Russia Encounters More Problems Sending Long-Delayed Module and Robotic Arm to Space Station (gizmodo.com) 41

First Slashdot reader Thelasko quotes the BBC's report Wednesday: A Russian rocket has departed the Baikonur Cosmodrome, Kazakhstan, to deliver a new science module to the International space station (ISS). The 13m-long, 20-tonne [44,000-pound] Nauka laboratory will go on the rear of the orbiting platform, connected to the other major Russian segments, Zvezda and Zarya. The new module carries with it a large robotic arm supplied by the European Space Agency (Esa).

Nauka is much delayed. It was originally supposed to launch in 2007. But it suffered repeated slips in schedule, in part because of budget difficulties but also because engineers encountered a raft of technical problems during development.

The module will result in a significant boost in habitable volume for the ISS, raising it by 70 cubic metres.

It's expected to dock this Thursday (July29), according to CBS News, after which "It will take up to 11 Russian spacewalks over about seven months to electrically connect and outfit the new lab module, providing a new airlock, research space, living quarters, a European Space Agency robot arm and other systems."

But Friday Gizmodo reported the attempt to deliver the module to the Space Station "is still having problems." The first glitch in Nauka's journey happened yesterday, when the spacecraft didn't complete its first orbit-raising burn. This meant that the uncrewed Nauka wasn't on track to actually intercept the ISS, which it's scheduled to dock with on Thursday, July 29. The problem was attributed to a software issue in a computer aboard Nauka, which prevented the spacecraft's main engines from firing. Nauka's team was able to manage a remote course correction, but a second bout of course corrections were deemed necessary, and scheduled for Friday...

Nauka's also been having issues with one antenna and its docking target, and its uncertain how those issues will affect docking attempts, SpaceNews reported. "Apparently there is still an issue with the Kurs rendezvous system, and that is pretty critical for docking," said Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, adding that the spacecraft's TORU system — which allows the astronauts aboard the ISS assist with the docking — is working normally. For now, the Pirs docking compartment is currently sitting in Nauka's assigned dock on the ISS. Pirs' scheduled undocking to make way for the new module was postponed from Friday to Sunday, .

RNA Breakthrough Creates High-Yield, Drought-Tolerant Rice, Potatoes (upi.com) 120

"Thanks to a breakthrough in RNA manipulation, crop scientists have developed new potato and rice varieties with higher yields and increased drought tolerance," reports UPI: By inserting a gene responsible for production of a protein called FTO, scientists produced bigger rice and potato plants with more expansive root systems. In experiments, the plants' longer roots improved their drought resistance.

Test results — detailed Thursday in the journal Nature Biotechnology — showed the RNA-manipulated plants also improved their rate of photosynthesis, boost yields by as much as 50 percent...

In the lab, the manipulated rice plants grew at three times their normal rate. In the field, the rice plants increased their mass by 50 percent. They also sprouted longer roots, increased their photosynthesis rate and produced larger yields. When they repeated the experiments with potato plants, the researchers got similar results, suggesting the new gene manipulation method could be used to bolster a variety of crops.

The researchers hope this could help crops survive climate change, and even prevent forests from being cleared for food production, according to the article. And one of the study's co-authors adds "This really provides the possibility of engineering plants to potentially improve the ecosystem as global warming proceeds."

Virtual Comic-Con Includes Trailers For 'Blade Runner' Series, 'Dune' Movie - and NASA Panels (space.com) 71

Comic-Con went virtual again in 2020. (San Diego businesses will miss the chance to profit from the 100,000 visitors the convention usually attracted.) And NPR reports the convention has gotten smaller in other ways: Both Marvel Studios and DC are staying away; as it did last year, DC is again directing its resources towards its own event, DC FanDome, set for mid-October. But fans of shows like Doctor Who, Dexter and Comic-Con stalwart The Walking Dead will have lots to look forward to.
Rotten Tomatoes and The Verge have gathered up the trailers that did premier. Some of the highlights:

But interestingly, one of the more visibile presenters was: NASA. Current and former NASA officials made appearances on several different panels, according to Space.com, including one on modern space law, U.N. treaty-making, and how it all stacks up against the portrayal we get in our various future-space franchises. And a former NASA astronaut was also part of a panel touting a virtual simulation platform, "where students can have access to the same tools that professionals use and in the case of space are given the opportunity to solve real problems related to missions to our Moon, Mars, and beyond... from piloting to terra-forming to creating habitats and spacecraft."

There was also a panel of four NASA engineers titled "No Tow Trucks Beyond Mars," on "how we go boldly where there's no one around to fix it. Hear stories from the trenches of the heartbreaks, close calls, and adventures of real-life landing (and flying!) on Mars and our round-table discussion of what Netflix got right in their movie Stowaway."

Sunday's panels will include an astronomer, an astrobiologist, and a geologist/paleontologist discussing "The Science of Star Wars" with the concept designer for Star Wars episodes 7-9, Rogue One, and Solo.

Three Die After Untreatable 'Superbug' Fungus Infections in Two Different Cities (go.com) 95

"U.S. health officials said Thursday they now have evidence of an untreatable fungus spreading in two hospitals and a nursing home," reports the Associated Press: The "superbug" outbreaks were reported in a Washington, D.C, nursing home and at two Dallas-area hospitals, the Centers for Disease Control and Prevention reported. A handful of the patients had invasive fungal infections that were impervious to all three major classes of medications. "This is really the first time we've started seeing clustering of resistance" in which patients seemed to be getting the infections from each other, said the CDC's Dr. Meghan Lyman...

Health officials have sounded alarms for years about the superbug after seeing infections in which commonly used drugs had little effect. In 2019, doctors diagnosed three cases in New York that were also resistant to a class of drugs, called echinocandins, that were considered a last line of defense. In those cases, there was no evidence the infections had spread from patient to patient — scientists concluded the resistance to the drugs formed during treatment. The new cases did spread, the CDC concluded....

Those cases were seen from January to April. Of the five people who were fully resistant to treatment, three died — both Texas patients and one in Washington.

Lyman said both are ongoing outbreaks and that additional infections have been identified since April. But those added numbers were not reported.

The fungus, Candida auris, "is a harmful form of yeast that is considered dangerous to hospital and nursing home patients with serious medical problems," they add — and it's spread through contaminated surfaces or contact with patients.

Newsweek points out that while it's only recently appeared in America, "infections have occurred in over 30 countries worldwide."

Society Is Right On Track For a Global Collapse, New Study of Infamous 1970s Report Finds 323

fahrbot-bot shares a report from Live Science: Human society is on track for a collapse in the next two decades if there isn't a serious shift in global priorities, according to a new reassessment of a 1970s report, Vice reported. In that report -- published in the bestselling book "The Limits to Growth" (1972) -- a team of MIT scientists argued that industrial civilization was bound to collapse if corporations and governments continued to pursue continuous economic growth, no matter the costs. The researchers forecasted 12 possible scenarios for the future, most of which predicted a point where natural resources would become so scarce that further economic growth would become impossible, and personal welfare would plummet.

The report's most infamous scenario -- the Business as Usual (BAU) scenario -- predicted that the world's economic growth would peak around the 2040s, then take a sharp downturn, along with the global population, food availability and natural resources. This imminent "collapse" wouldn't be the end of the human race, but rather a societal turning point that would see standards of living drop around the world for decades, the team wrote.

So, what's the outlook for society now, nearly half a century after the MIT researchers shared their prognostications? Gaya Herrington, a sustainability and dynamic system analysis researcher at the consulting firm KPMG, decided to find out. [...] Herrington found that the current state of the world -- measured through 10 different variables, including population, fertility rates, pollution levels, food production and industrial output -- aligned extremely closely with two of the scenarios proposed in 1972, namely the BAU scenario and one called Comprehensive Technology (CT), in which technological advancements help reduce pollution and increase food supplies, even as natural resources run out. While the CT scenario results in less of a shock to the global population and personal welfare, the lack of natural resources still leads to a point where economic growth sharply declines -- in other words, a sudden collapse of industrial society.
"The good news is that it's not too late to avoid both of these scenarios and put society on track for an alternative -- the Stabilized World (SW) scenario," the report notes. "This path begins as the BAU and CT routes do, with population, pollution and economic growth rising in tandem while natural resources decline. The difference comes when humans decide to deliberately limit economic growth on their own, before a lack of resources forces them to."

"The SW scenario assumes that in addition to the technological solutions, global societal priorities change," Herrington wrote. "A change in values and policies translates into, amongst other things, low desired family size, perfect birth control availability, and a deliberate choice to limit industrial output and prioritize health and education services." After this shift of values occurs, industrial growth and global population begin to level out. "Food availability continues to rise to meet the needs of the global population; pollution declines and all but disappears; and the depletion of natural resources begins to level out, too," adds Live Science. "Societal collapse is avoided entirely."

Oregon Congressman Proposes New Space Tourism Tax (space.com) 155

U.S. Rep. Earl Blumenauer (D-Oregon) plans to introduce legislation called the Securing Protections Against Carbon Emissions (SPACE) Tax Act, which would impose new excise taxes on space tourism trips. Space.com reports: "Space exploration isn't a tax-free holiday for the wealthy. Just as normal Americans pay taxes when they buy airline tickets, billionaires who fly into space to produce nothing of scientific value should do the same, and then some," Blumenauer said in a statement issued by his office. "I'm not opposed to this type of space innovation," added Blumenauer, a senior member of the House of Representatives' Ways and Means Committee. "However, things that are done purely for tourism or entertainment, and that don't have a scientific purpose, should in turn support the public good."

The proposed new tax would likely be levied on a per-passenger basis, as is done with commercial aviation, the statement said. "Exemptions would be made available for NASA spaceflights for scientific research purposes," the statement reads. "In the case of flights where some passengers are working on behalf of NASA for scientific research purposes and others are not, the launch excise tax shall be the pro rata share of the non-NASA researchers." There would be two taxation tiers, one for suborbital flights and another for missions that reach orbit. The statement did not reveal how much the tax would be in either case or if the collected revenue would be earmarked for any specific purpose. Such a purpose could be the fight against climate change, if the proposed act's full name is any guide. Blumenauer is concerned about the potential carbon footprint of the space tourism industry once it gets fully up and running, the statement said.

Maker of Dubious $56K Alzheimer's Drug Offers Cognitive Test No One Can Pass (arstechnica.com) 56

An anonymous reader quotes a report from Ars Technica: Do you ever forget things, like a doctor's appointment or a lunch date? Do you sometimes struggle to think of the right word for something common? Do you ever feel more anxious or irritable than you typically do? Do you ever feel overwhelmed when trying to make a decision? If you answered "no, never" to all of those questions, there's a possibility that you may not actually be human. Nevertheless, you should still talk to a doctor about additional cognitive screenings to check if you have Alzheimer's disease. At least, that's the takeaway from a six-question quiz provided in part by Biogen, the maker of an unproven, $56,000 Alzheimer's drug.

The six questions include the four above, plus questions about whether you ever lose your train of thought or ever get lost on your way to or around a familiar place. The questions not only bring up common issues that perfectly healthy people might face from time to time, but the answers any quiz-taker provides are also completely irrelevant. No matter how you answer -- even if you say you never experience any of those issues -- the quiz will always prompt you to talk with your doctor about cognitive screening. The results page even uses your zip code to provide a link to find an Alzheimer's specialist near you. Biogen says the quiz website is part of a "disease awareness educational program." But it appears to be part of an aggressive strategy to sell the company's new Alzheimer's drug, Aduhelm, which has an intensely controversial history, to say the least.
What's the controversial history you may ask? According to Ars, the drug "flunked out of two identical Phase III clinical trials in 2019." A panel of expert advisors for the FDA overwhelmingly voted against approval, yet it still was approved by the FDA on June 7. It also has a list price of $56,000 for a year's supply.

The report goes on to say that the company is basically making up the statistic that "about 1 in 12 Americans 50 years and older" has mild cognitive impairment due to Alzheimer's. Experts say they know of no evidence to back up that statistic and it appears to be a significant overestimate.

Furthermore, two medical experts from Georgetown University said the company's quiz website "appears designed to ratchet up anxiety in anyone juggling multiple responsibilities or who gets distracted during small talk." They added: "Convincing perfectly normal people they should see a specialist, be tested for amyloid plaque, and, if present, assume they have early Alzheimer's is a great strategy for increasing Aduhelm prescriptions... [It] could lead to millions of prescriptions -- and billions of dollars in profit -- for an ineffective and expensive drug."

Jeff Bezos and Sir Richard Branson Not Yet Astronauts, US Says (bbc.com) 80

New Federal Aviation Administration (FAA) rules say astronaut hopefuls must be part of the flight crew and make contributions to space flight safety. That means Jeff Bezos and Sir Richard Branson may not yet be astronauts in the eyes of the US government. The BBC reports: These are the first changes since the FAA wings program began in 2004. The Commercial Astronaut Wings program updates were announced on Tuesday -- the same day that Amazon's Mr Bezos flew aboard a Blue Origin rocket to the edge of space. To qualify as commercial astronauts, space-goers must travel 50 miles (80km) above the Earth's surface, which both Mr Bezos and Mr Branson accomplished. But altitude aside, the agency says would-be astronauts must have also "demonstrated activities during flight that were essential to public safety, or contributed to human space flight safety." What exactly counts as such is determined by FAA officials.

In a statement, the FAA said that these changes brought the wings scheme more in line with its role to protect public safety during commercial space flights. On July 11, Sir Richard flew on-board Virgin Galactic's SpaceShipTwo to the edge of space as a test before allowing customers aboard next year. Mr Bezos and the three other crew members who flew on Blue Origin's spacecraft may have less claim to the coveted title. Ahead of the launch, Blue Origin CEO Bob Smith said that "there's really nothing for a crew member to do" on the autonomous vehicle. Those wishing for commercial wings need to be nominated for them as well. An FAA spokesperson told CNN they are not currently reviewing any submissions.

There are two other ways to earn astronaut wings in the US - through the military or Nasa. However, a glimmer of hope remains for Sir Richard, Mr Bezos and any future stargazers hoping to be recognized as astronauts. The new order notes that honorary awards can be given based on merit -- at the discretion of the FAA's associate administrator. Astronaut wings were first awarded to astronauts Alan Shepard Jr and Virgil Grissom in the early 1960s for their participation in the Mercury Seven program.

A 3-degree Celsius World Has No Safe Place (economist.com) 229

The extremes of floods and fires are not going away, but adaptation can lessen their impact. Economist (paywalled): If temperatures rise by 3C above pre-industrial levels in the coming decades -- as they might even if everyone manages to honour today's firm pledges -- large parts of the tropics risk becoming too hot for outdoor work. Coral reefs and the livelihoods that depend on them will vanish and the Amazon rainforest will become a ghost of itself. Severe harvest failures will be commonplace. Ice sheets in Antarctica and Greenland will shrink past the point of no return, promising sea rises measured not in millimetres, as today's are, but in metres.

Six years ago, in Paris, the countries of the world committed themselves to avoiding the worst of that nightmare by eliminating net greenhouse-gas emissions quickly enough to hold the temperature rise below 2C. Their progress towards that end remains woefully inadequate. Yet even if their efforts increased dramatically enough to meet the 2C goal, it would not stop forests from burning today; prairies would still dry out tomorrow, rivers break their banks and mountain glaciers disappear. Cutting emissions is thus not enough. The world also urgently needs to invest in adapting to the changing climate. The good news is that adaptation makes political sense. People can clearly see the need for it. When a country invests in flood defences it benefits its own citizens above all others -- there is no free-rider problem, as there could be for emissions reduction. Nor does all the money come from the public purse; companies and private individuals can see the need for adaptation and act on it. When they do not do so, insurance companies can open their eyes to the risks they are running.

Some adaptation is fairly easily set in place. Systems for warning Germans of coming floods will surely now improve. But other problems require much larger public investment, like that which has been put into water-management in the Netherlands. Rich countries can afford such things. Poor countries and poor people need help, which is why the Paris climate agreement calls for annual transfers of $100bn from rich to poor. The rich countries have not yet lived up to their side of this. On July 20th John Kerry, President Joe Biden's special envoy on climate change, reiterated America's pledge to triple its support to $1.5bn for adaptation in poorer countries by 2024, part of a broader move to increase investment in adaptation and mitigation in developing countries. More such efforts are vital.

Most Unvaccinated Americans Don't Want Shots: AP-NORC Poll (apnews.com) 657

Most Americans who haven't been vaccinated against COVID-19 say they are unlikely to get the shots and doubt they would work against the aggressive delta variant despite evidence they do, according to a new poll that underscores the challenges facing public health officials amid soaring infections in some states. AP: Among American adults who have not yet received a vaccine, 35% say they probably will not, and 45% say they definitely will not, according to a poll from The Associated Press-NORC Center for Public Affairs Research. Just 3% say they definitely will get the shots, though another 16% say they probably will. What's more, 64% of unvaccinated Americans have little to no confidence the shots are effective against variants -- including the delta variant that officials say is responsible for 83% of new cases in the U.S. -- despite evidence that they offer strong protection. In contrast, 86% of those who have already been vaccinated have at least some confidence that the vaccines will work.

That means "that there will be more preventable cases, more preventable hospitalizations and more preventable deaths," said Dr. Amesh Adalja, an infectious disease specialist at Johns Hopkins University. "We always knew some proportion of the population would be difficult to persuade no matter what the data showed, (and) a lot of people are beyond persuasion," said Adalja. He echoed Centers for Disease Control and Prevention Director Rochelle Walensky in calling the current surge "a pandemic of the unvaccinated" because nearly all hospital admissions and deaths have been among those who weren't immunized.

39-Year-Old Becomes First US Patient To Receive 'Aeson' Artificial Heart Implant (sciencealert.com) 25

An anonymous reader quotes a report from ScienceAlert: [A] team of surgeons has successfully completed the first human implantation in the US of an artificial heart device called the 'Aeson', developed by French company CARMAT. The artificial heart has two ventricular chambers and four biological valves, just like the real organ, and is powered by an external device. Made from "biocompatible materials" including bovine tissue, the artificial heart uses a combination of sensors and algorithms to maintain its pace and keep blood circulating through the body. "We are encouraged that our patient is doing so well after the procedure," says cardiologist Carmelo Milano from the Duke University School of Medicine. "As we evaluate this device, we are both excited and hopeful that patients who otherwise have few to no options could have a lifeline."

The patient in question is 39-year-old Matthew Moore, from Shallotte in North Carolina. Moore was initially due to have heart bypass surgery, but as his condition deteriorated the medical staff started to run out of options; he became so ill that even a regular heart transplant was too risky. Fortunately, he was in the right place: the Aeson device is being tested at Duke University, pending approval from the US Food and Drug Administration (FDA). It's already been given the green light for use by regulators in Europe, after several years of tests in European patients, not all of which have been successful. The artificial heart has been developed specifically to help those whose hearts can no longer pump enough blood through both chambers. It replaces the entire natural heart, although it's not intended to be permanent -- it's designed to be a bridge towards a full heart transplant within six months or so.

Google Turns AlphaFold Loose On the Entire Human Genome (arstechnica.com) 20

An anonymous reader quotes a report from Ars Technica: Just one week after Google's DeepMind AI group finally described its biology efforts in detail, the company is releasing a paper that explains how it analyzed nearly every protein encoded in the human genome and predicted its likely three-dimensional structure -- a structure that can be critical for understanding disease and designing treatments. In the very near future, all of these structures will be released under a Creative Commons license via the European Bioinformatics Institute, which already hosts a major database of protein structures. In a press conference associated with the paper's release, DeepMind's Demis Hassabis made clear that the company isn't stopping there. In addition to the work described in the paper, the company will release structural predictions for the genomes of 20 major research organisms, from yeast to fruit flies to mice. In total, the database launch will include roughly 350,000 protein structures.
[...]
At some point in the near future (possibly by the time you read this), all this data will be available on a dedicated website hosted by the European Bioinformatics Institute, a European Union-funded organization that describes itself in part as follows: "We make the world's public biological data freely available to the scientific community via a range of services and tools." The AlphaFold data will be no exception; once the above link is live, anyone can use it to download information on the human protein of their choice. Or, as mentioned above, the mouse, yeast, or fruit fly version. The 20 organisms that will see their data released are also just a start. DeepMind's Demis Hassabis said that over the next few months, the team will target every gene sequence available in DNA databases. By the time this work is done, over 100 million proteins should have predicted structures. Hassabis wrapped up his part of the announcement by saying, "We think this is the most significant contribution AI has made to science to date." It would be difficult to argue otherwise.

AI Firm DeepMind Puts Database of the Building Blocks of Life Online (theguardian.com) 19

Last year the artificial intelligence group DeepMind cracked a mystery that has flummoxed scientists for decades: stripping bare the structure of proteins, the building blocks of life. Now, having amassed a database of nearly all human protein structures, the company is making the resource available online free for researchers to use. From a report: The key to understanding our basic biological machinery is its architecture. The chains of amino acids that comprise proteins twist and turn to make the most confounding of 3D shapes. It is this elaborate form that explains protein function; from enzymes that are crucial to metabolism to antibodies that fight infectious attacks. Despite years of onerous and expensive lab work that began in the 1950s, scientists have only decoded the structure of a fraction of human proteins.

DeepMind's AI program, AlphaFold, has predicted the structure of nearly all 20,000 proteins expressed by humans. In an independent benchmark test that compared predictions to known structures, the system was able to predict the shape of a protein to a good standard 95% of time. DeepMind, which has partnered with the European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI), hopes the database will help researchers to analyse how life works at an atomic scale by unpacking the apparatus that drives some diseases, make strides in the field of personalised medicine, create more nutritious crops and develop "green enzymes" that can break down plastic.

After Repair, Hubble Captures Images of 'Rarely Observed' Colliding Galaxies (cbsnews.com) 21

UnknowingFool shares a report from CBS News: After being down for a month due to a computer issue, Hubble was brought back up last week. NASA released images captured by Hubble over the weekend including a rare observance of two galaxies that are colliding. The other interesting image is that of a spiral galaxy with three arms, as most spiral galaxies have an even number of arms. "I'm thrilled to see that Hubble has its eye back on the universe, once again capturing the kind of images that have intrigued and inspired us for decades," NASA administrator Bill Nelson said in a statement. "This is a moment to celebrate the success of a team truly dedicated to the mission. Through their efforts, Hubble will continue its 32nd year of discovery, and we will continue to learn from the observatory's transformational vision."

Drones Are Zapping Clouds With Electricity To Create Rain In UAE Project (usatoday.com) 45

turp182 shares a report from USA Today: [T]he UAE is now testing a new method that has drones fly into clouds to give them an electric shock to trigger rain production [...]. The project is getting renewed interest after the UAE's National Center of Meteorology recently published a series of videos on Instagram of heavy rain in parts of the country. Water gushed past trees, and cars drove on rain-soaked roads. The videos were accompanied by radar images of clouds tagged "#cloudseeding." The Independent reports recent rain is part of the drone cloud seeding project.

The UAE oversaw more than 200 cloud seeding operations in the first half of 2020, successfully creating excess rainfall, the National News reported. There have been successes in the U.S., as well as China, India, and Thailand. Long-term cloud seeding in the mountains of Nevada have increased snowpack by 10% or more each year, according to research published by the American Meteorological Society. A 10-year cloud seeding experiment in Wyoming resulted in 5-10% increases in snowpack, according to the State of Wyoming.
According to a researcher that worked on the drone initiative, "the aim of the UAE's project is to change the balance of electrical charge on the cloud droplets, causing water droplets to clump together and fall as rain when they are big enough."

Australia's Giant Carbon Capture Project Fails To Meet Key Targets (smh.com.au) 89

The world's largest carbon capture and storage project has failed to meet a crucial target of capturing and burying an average of 80% of the carbon dioxide produced from gas wells in Western Australia over five years. From a report: The energy giant Chevron agreed to the target with the West Australian government when developing its $54 billion Gorgon project to extract and export gas from fields off the WA coast. The five year milestone passed on Sunday. In a statement the energy giant Chevron announced that since operations began in August 2019 it had injected five million tonnes of greenhouse gases underground. According to the independent analyst Peter Milne, that leaves a shortfall of around 4.6 million tonnes, which he estimates would cost about $100 million to offset via carbon credits.

The project has national and even international significance, with the oil and gas industry and the federal government declaring the success of carbon capture and storage to be crucial in tackling climate change while making use of fossil fuels. "It is essential we position Australia to succeed by investing now in the technologies that will support our industries into the future, with lower emissions energy that can support Australian jobs," Prime Minister Scott Morrison said in April while announcing $263.7 million in funding to develop carbon capture and storage technology.

15,000-Year-Old Viruses Discovered In Tibetan Glacier Ice (osu.edu) 133

An anonymous reader quotes a report from Ohio State News: Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date. The findings, published today in the journal Microbiome, could help scientists understand how viruses have evolved over centuries. For this study, the scientists also created a new, ultra-clean method of analyzing microbes and viruses in ice without contaminating it.

The researchers analyzed ice cores taken in 2015 from the Guliya ice cap in western China. The cores are collected at high altitudes -- the summit of Guliya, where this ice originated, is 22,000 feet above sea level. The ice cores contain layers of ice that accumulate year after year, trapping whatever was in the atmosphere around them at the time each layer froze. Those layers create a timeline of sorts, which scientists have used to understand more about climate change, microbes, viruses and gases throughout history. Researchers determined that the ice was nearly 15,000 years old using a combination of traditional and new, novel techniques to date this ice core. When they analyzed the ice, they found genetic codes for 33 viruses. Four of those viruses have already been identified by the scientific community. But at least 28 of them are novel. About half of them seemed to have survived at the time they were frozen not in spite of the ice, but because of it.

Jeff Bezos On Critics of Billionaires Going To Space: 'They're Mostly Right' (cnbc.com) 238

An anonymous reader quotes a report from CNBC: Jeff Bezos has heard the complaints about billionaires like himself funneling their money into private rocket companies instead of donating to causes on Earth, and he doesn't disagree. In an interview with CNN ahead of his planned Tuesday morning space voyage in a rocket built by his company Blue Origin, Bezos was asked for his thoughts on critics who call the extraterrestrial flights "joyrides for the wealthy, and [who say] you should be spending your time and your money and energy trying to solve problems here on Earth." "Well, I say they are largely right," said Bezos, who Bloomberg estimates is worth $206 billion. "We have to do both. We have lots of problems here on Earth and we have to work on those."

Bezos and fellow billionaires [...] have been characterized by critics as deaf to issues on the ground and too obsessed with making space more accessible when they could put their resources elsewhere. The 57-year-old Bezos, who earlier this month stepped down as CEO of Amazon, said it's important to "look to the future ... as a species and as a civilization." In his view, the work being done today will lay the foundation for future generations to work in space, which "will solve problems here on Earth."
In an opinion piece for MSNBC, Talia Lavin views billionaires going to space through a more incendiary lens, writing: "What they seek to leave behind is a planet burning and flooding and full of the kind of small and ordinary suffering such fortunes could alleviate in an instant."

The space program of the 1960s, which resulted in the first crewed mission to land on the Moon, "may have been mired in the bitter and petty rivalries of the Cold War, and limned by prejudice about who could excel," writes Lavin, "but it was a project funded and created by our government, an achievement held in common by the masses. No such common pride can be held in the launch of the titans of capital."

"In this billionaire battle, there is no pretense at a sense of collective pride or communal achievement. Even the drumbeat of nationalism would be better than this obscene egotism, whose fumes are more putrid than rocket-jet emissions. It feels like a parody of hubris, and a colossal celebration of the social failure to moderate preposterous accumulations of wealth."
