Quake-Measuring Device on Mars Gets Detailed Look at Red Planet's Interior (apnews.com) 10
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
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
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
Rotten Tomatoes and The Verge have gathered up the trailers that did premier. Some of the highlights:
- Blade Runner: Black Lotus , an upcoming anime television series set to premiere in late 2021 on Crunchyroll and Adult Swim (co-producing it with Alcon Television Group).
- The upcoming remake of Dune
- J.J. Abrams' new four-part Showtime documentary about UFOs.
- Season 2 of Star Trek: Lower Decks and the new Star Trek: Prodigy, a CGI-animated series about a group of aliens who escape captivity onboard the Enterprise.
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
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
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
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
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
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
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
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
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
[...]
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
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.

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