NASA's first new space potty in decades -- a $23 million titanium toilet better suited for women -- is getting a not-so-dry run at the International Space Station before eventually flying to the moon. The Associated Press reports: Barely 100 pounds (45 kilograms) and just 28 inches (71 centimeters) tall, the new toilet is roughly half as big as the two Russian-built ones at the space station. It's more camper-size to fit into the NASA Orion capsules that will carry astronauts to the moon in a few years. Station residents will test it out for a few months. If the shakedown goes well, the toilet will be open for regular business. The old toilets cater more toward men. To better accommodate women, NASA tilted the seat on the new toilet and made it taller. The new shape should help astronauts position themselves better for No. 2, said Johnson Space Center's Melissa McKinley, the project manager. "Cleaning up a mess is a big deal. We don't want any misses or escapes," she said.

As for No. 1, the funnels also have been redesigned. Women can use the elongated and scooped-out funnels to urinate while sitting on the commode to poop at the same time, McKinley said. Until now, it's been one or the other for female astronauts, she noted. Like earlier space commodes, air suction, rather than water and gravity, removes the waste. Urine collected by the new toilet will be routed into NASA's long-standing recycling system to produce water for drinking and cooking. Titanium and other tough alloys were chosen for the new toilet to withstand all the acid in the urine pretreatment.

An anonymous reader quotes a report from IEEE Spectrum: This work, done by two researchers at Binghamton University (Umur Aybars Ciftci and Lijun Yin) and one at Intel (Ilke Demir), was published in IEEE Transactions on Pattern Analysis and Machine Learning this past July. In an article titled, "FakeCatcher: Detection of Synthetic Portrait Videos using Biological Signals," the authors describe software they created that takes advantage of the fact that real videos of people contain physiological signals that are not visible to the eye. In particular, video of a person's face contains subtle shifts in color that result from pulses in blood circulation. You might imagine that these changes would be too minute to detect merely from a video, but viewing videos that have been enhanced to exaggerate these color shifts will quickly disabuse you of that notion. This phenomenon forms the basis of a technique called photoplethysmography, or PPG for short, which can be used, for example, to monitor newborns without having to attach anything to a their very sensitive skin.

Deep fakes don't lack such circulation-induced shifts in color, but they don't recreate them with high fidelity. The researchers at SUNY and Intel found that "biological signals are not coherently preserved in different synthetic facial parts" and that "synthetic content does not contain frames with stable PPG." Translation: Deep fakes can't convincingly mimic how your pulse shows up in your face. The inconsistencies in PPG signals found in deep fakes provided these researchers with the basis for a deep-learning system of their own, dubbed FakeCatcher, which can categorize videos of a person's face as either real or fake with greater than 90 percent accuracy. And these same three researchers followed this study with another demonstrating that this approach can be applied not only to revealing that a video is fake, but also to show what software was used to create it. In a newer paper (PDF), researchers showed that they "can distinguish with greater than 90 percent accuracy whether the video was real, or which of four different deep-fake generators was used to create a bogus video," the report adds.

Twitter told Motherboard that it will suspend people who openly hope Trump dies from the coronavirus, which he recently tested positive for and, as a result, was moved to Walter Reed hospital "out of an abundance of caution." Twitter referred to an "abusive behavior" rule that's been on the books since April. From the report: "Content that wishes, hopes or expresses a desire for death, serious bodily harm or fatal disease against an individual is against our rules," Twitter said in a statement. This rule will apparently apply to people who wish death on Trump, who is the single most powerful person in the world.

As Motherboard has previously reported, Facebook has different rules for speech that is focused on celebrities and public figures. Facebook says it "distinguish[es] between public figures and private individuals because we want to allow discussion, which often includes critical commentary of people who are featured in the news or who have a large public audience. For public figures, we remove attacks that are severe as well as certain attacks where the public figure is directly tagged in the post or comment." What this means is that it's OK to post on Facebook that you hope Trump dies, so long as you do not tag him in the post or "purposefully expose" him to "calls for death, serious disease, epidemic disease, or disability." Twitter makes no such distinction between public and private figures. With that said, Twitter said that it "won't take enforcement action on every tweet. We're prioritizing the removal of content when it has a clear call to action that could potentially cause real-world harm."

The heart monitoring feature on the Apple Watch may lead to unnecessary health care visits, according to a new study published this week. The Verge reports: Only around 10 percent of people who saw a doctor at the Mayo Clinic after noticing an abnormal pulse reading on their watch were eventually diagnosed with a cardiac condition. The finding shows that at-home health monitoring devices can lead to over-utilization of the health care system, said study author Heather Heaton, an assistant professor of emergency medicine at the Mayo Clinic College of Medicine, in an email to The Verge. That may be expensive for patients and for the system as a whole, and it may take up doctor and patient time unnecessarily.

Heaton and the study team scanned patient health records at every Mayo Clinic site, including offices in Arizona, Florida, Wisconsin, and Iowa, for mentions of the term "Apple Watch" over a six-month period from December 2018 to April 2019. The window came just after Apple introduced a feature to detect abnormal heart rhythms and after publication of a study tracking how well the watches could detect atrial fibrillation. They found records of 264 patients who said their Apple Watches flagged a concerning heart rhythm. Of that group, 41 explicitly mentioned getting an alert from their watch (others may have had an alert, but it wasn't mentioned specifically in their health record). Half of the patients already had a cardiac diagnosis, including 58 who'd been previously diagnosed with atrial fibrillation. About two-thirds had symptoms, including lightheadedness or chest pain. Only 30 patients in the study got a cardiac diagnosis after their doctors visit. Most of the concerning heart monitor data, then, were probably false positives, the study concluded.

President Donald Trump has been flown to the hospital less than 24 hours after testing positive for COVID-19. The BBC reports: The White House said the decision to transport him to Walter Reed National Military Medical Center was taken "out of an abundance of caution." Mr Trump began exhibiting "mild symptoms" of Covid-19 on Thursday. He said early on Friday he and First Lady Melania Trump had tested positive. The White House said he was feeling "fatigued but in good spirits."

Wearing a mask and suit, Mr Trump walked out across the White House lawn on Friday afternoon to his helicopter, Marine One, for the short trip to hospital. He waved and gave a thumbs-up to reporters but said nothing before boarding the aircraft. In a video posted to Twitter, Mr Trump said: "I want to thank everybody for the tremendous support. I'm going to Walter Reed hospital. I think I'm doing very well. But we're going to make sure that things work out. The first lady is doing very well. So thank you very much, I appreciate it, I will never forget it -- thank you."

Uncertainty can be hard for humans. It drives anxiety, an emotion neuroscientists are trying to understand and psychologists are trying to better treat. From a report: Under the threat of a virus, job insecurity, election uncertainty, and a general pandemic life-in-limbo that is upending school, holidays and more, people are especially anxious. Before the pandemic, anxiety was already climbing in the U.S., especially among young adults, according to a recent study. Add the pandemic and its many unknowns: 35% of adults in the Household Pulse Survey reported symptoms of anxiety disorder in July. (In the first half of 2019, it was roughly 8%.) "We have anxiety for a reason," says Stephanie Gorka, who studies the neurobiology of anxiety and treatments for anxiety-related disorders and phobias at the Ohio State University. Anxiety alerts people to pay attention to their environment and is key to our survival, but if it is chronic or excessive, it can have negative health consequences, she says. But how exactly the brain responds to uncertainty and leads to anxiety is unclear.

hackingbear shares a report from CNN: As October 1 arrives, hundreds of millions of people in China are expected to pack highways, trains and planes for the National Day holiday, one of the busiest times for travel in the world's most populous country. In a sign of the government's confidence in keeping the virus under control, the Chinese Center for Disease Control and Prevention said last week that domestic travels can be arranged "as normal" for the upcoming holiday, given all cities in mainland China are marked as low risk for the coronavirus. The expected 550 million trips during the 8-day holiday will be a much-awaited boost to Chinese economic recovery. "I think China has (the virus) under pretty good control," said a 29-year-old traveler flew from Guangzhou to Shanghai. "I'm wearing masks and bringing alcohol wipes with me to clean my hands, especially before eating -- although in Shanghai, few people wear masks now." More than eight months on, China's restrictions on domestic movement have all been lifted. Officially, some cities still require passengers to produce a green health code on their smartphones at train stations and airports to show they're safe to travel, but implementation can be lax in practice. China has not reported any locally transmitted symptomatic case since mid-August, and is rigorously screening overseas arrivals and workers at risk of exposure to the virus. In other coronavirus-related news, vaccine trial participants are reporting day-long exhaustion, fever and headaches -- but say it's worth it. Slashdot reader gollum123 shares a report from CNBC: Luke Hutchison woke up in the middle of the night with chills and a fever after taking the Covid-19 booster shot in Moderna's vaccine trial. Another coronavirus vaccine trial participant, testing Pfizer's candidate, similarly woke up with chills, shaking so hard he cracked a tooth after taking the second dose. High fever, body aches, bad headaches and exhaustion are just some of the symptoms five participants in two of the leading coronavirus vaccine trials say they felt after receiving the shots. While the symptoms were uncomfortable, and at times intense, they often went away after a day, sometimes sooner, according to three participants in the Moderna trial and one in Pfizer's as well as a person close to another participant in Moderna's trial. Hutchison said he's concerned that the pharmaceutical manufacturers have not sufficiently informed the public about potential side effects. If the vaccines are approved, he fears, it might cause a widespread backlash if word spreads, which is why he decided to go public now.

An anonymous reader quotes a report from Popular Mechanics: For the first time, scientists have observed an interaction of a rare and baffling form of matter called time crystals. The crystals look at a glance like "regular" crystals, but they have a relationship to time that both intrigues and puzzles scientists because of its unpredictability. Now, experts say they could have applications in quantum computing. [...] Researchers say they've collided two time crystals to see what happens next. "Our results demonstrate that time crystals obey the general dynamics of quantum mechanics and offer a basis to further investigate the fundamental properties of these phases, opening pathways for possible applications in developing fields, such as quantum information processing," they explain in a new paper.

In their experiments, they placed two time crystals in superfluid and mixed magnons between them. Magnons are a magnetic quasiparticle that, in this case, led to "opposite-phase oscillations," while the crystals themselves stayed phase stable. What's cool (and, literally, supercooled) is how the matter acts within predictable quantum mechanical ways despite the central quality of wild oscillation patterns over time. "Before this, nobody had observed two time crystals in the same system, let alone seen them interact," lead author Samuli Autti, of Lancaster University, said in a statement. "Controlled interactions are the number one item on the wish list of anyone looking to harness a time crystal for practical applications, such as quantum information processing."

Michele Solis, writing for Scientific American: In a perfect world, we would learn from success and failure alike. Both hold instructive lessons and provide needed reality checks that may safeguard our decisions from bad information or biased advice. But, alas, our brain doesn't work this way. Unlike an impartial outcome-weighing machine an engineer might design, it learns more from some experiences than others. A few of these biases may already sound familiar: A positivity bias causes us to weigh rewards more heavily than punishments. And a confirmation bias makes us take to heart outcomes that confirm what we thought was true to begin with but discount those that show we were wrong. A new study, however, peels away these biases to find a role for choice at their core. A bias related to the choices we make explains all the others, says Stefano Palminteri of the French National Institute for Health and Medical Research (INSERM), who conducted a study published in Nature Human Behaviour in August that examines this tendency. "In a sense we have been perfecting our understanding of this bias," he says.

An anonymous reader quotes a report from The Guardian: Greenland's ice is starting to melt faster than at any time in the past 12,000 years, research has shown, which will raise sea levels and could have a marked impact on ocean currents. New measurements show the rate of melting matches any in the geological record for the Holocene period -- defined as the period since the last ice age -- and is likely to accelerate, according to a paper published in the journal Nature. The increased loss of ice is likely to lead to sea level rises of between 2cm and 10cm by the end of the century from Greenland alone, according to the study.

These changes, over the relatively short period of less than a century, appear to be unprecedented. Greenland's ice sheet shrank between 10,000 and 7,000 years ago, and has been slowly cumulating over the past 4,000 years. The current melting will reverse that pattern and within the next 1,000 years, if global heating continues, the vast ice sheet is likely to vanish altogether. If greenhouse gas emissions continue to rise strongly, the rate of melting could accelerate further to be four times greater than anything found in the past 12,000 years.

The team behind the latest Greenland study made their estimates by producing a computer model of a section of the south-western region of the ice sheet over the past 12,000 years and then projecting forward to the end of this century. They checked their findings against what we can tell actually occurred with the ice, through satellite measurements and other instruments, and also by mapping the position of boulders containing beryllium-10. These are deposited by glaciers as they move, and measurements of beryllium-10 can reveal how long the boulders have been in position, and therefore where the edge of the ice sheet was when the boulder was deposited.

AmiMoJo writes: Americans exercise their right to vote from all over the world, and for November's election, few ballots will have traveled as far as those cast by NASA astronauts living and working aboard the International Space Station. During earlier days of human spaceflight, astronauts would only visit space for days, or maybe weeks, at a time. Today, astronauts typically stay in space for six-month missions on the space station, increasing the odds of a spacefarer off the planet during an election. So how does one vote from space? Like other forms of absentee voting, voting from space starts with a Federal Postcard Application, or FPCA. It's the same form military members and their families fill out while serving outside of the U.S. By completing it ahead of their launch, space station crew members signal their intent to participate in an election from space. Because astronauts move to Houston for their training, most opt to vote as Texas residents. Of course, NASA's astronauts come from all over, so those wishing to vote as residents of their home states can work with their counties to make special arrangements to vote from space.

Once their FPCA is approved, the astronaut is almost ready to vote. Like many great things in space, voting starts with an experiment. The county clerk who manages elections in the astronaut's home county sends a test ballot to a team at NASA's Johnson Space Center in Houston. Then they use a space station training computer to test whether they're able to fill it out and send it back to the county clerk. After a successful test, a secure electronic ballot generated by the Clerk's office of Harris County and surrounding counties in Texas, is uplinked by Johnson's Mission Control Center to the voting crew member. An e-mail with crew member-specific credentials is sent from the County Clerk to the astronaut. These credentials allow the crew member to access the secure ballot. The astronaut will then cast their vote, and the secure, completed ballot is downlinked and delivered back to the County Clerk's Office by e-mail to be officially recorded. The clerk has their own password to ensure they are the only one who can open the ballot. It's a quick process, and the astronaut must be sure to submit it by 7 p.m. local time on Election Day if voting as a Texas resident.

Will astronauts vote in this election? Expedition 63/64 crew member Kate Rubins is assigned to a six-month mission launching Oct. 14, and will vote from space. It won't be her first time -- Rubins also cast her vote from the International Space Station during the 2016 election. With a SpaceX Crew Dragon scheduled to carry three additional U.S. crew members to the space station on Oct. 31 as part of the Crew-1 mission, Mike Hopkins, Victor Glover and Shannon Walker will make it to the space station just in time to cast their ballots there, as well. All three have filled out the paperwork and are ready to do so.

A jet suit for paramedics which would see patients reached in minutes by a "flying" medic has been tested by the Great North Air Ambulance Service. The BBC reports: After a year of talks between GNAAS and Gravity Industries, a first test flight was carried out in the Lake District. Andy Mawson, director of operations at GNAAS, came up with the idea and described seeing it as "awesome." He said it meant a paramedic could "fly" to a fell top in 90 seconds rather than taking 30 minutes on foot.

The test flight was carried out by Richard Browning, founder of Gravity Industries. He said the suits had two mini engines on each arm and one on the back allowing the paramedic to control their movement just by moving their hands. "The biggest advantage is its speed," Mr Mawson said. "If the idea takes off, the flying paramedic will be armed with a medical kit, with strong pain relief for walkers who may have suffered fractures, and a defibrillator for those who may have suffered a heart attack. In a jet pack, what might have taken up to an hour to reach the patient may only take a few minutes, and that could mean the difference between life and death."

An anonymous reader quotes a report from The Guardian: Tesco is to become the first UK retailer to set a sales target for plant-based alternatives to meat as it steps up efforts to offer shoppers more sustainable options. The UK's largest supermarket will on Tuesday commit to boosting sales of meat alternatives by 300% within five years, by 2025. Over the past year, demand for chilled meat-free foods -- the most popular line including burger, sausage and mince substitutes -- has increased by almost 50%, the retailer said. As a result, it is expanding into more categories and creating larger "centerpiece" dishes for two people as well as family-sized portions.

The target is part of a wider package of sustainability measures developed with its charity partner the World Wide Fund for Nature (WWF) to try to halve the environmental impact of the average UK shopping basket. Dave Lewis, who steps down as Tesco chief executive on Wednesday, said: "We know from tackling food waste that transparency and ambitious targets are the first steps towards becoming a more sustainable business." Among 11 new plant-based foods going on sale at Tesco this week are centerpiece dishes using the wheat protein favorite seitan as a meat substitute, including a beef-free joint and hunter's chicken-free traybake. Turkey-free crowns and vegan mince pies are launching in time for Christmas.

JoshuaZ writes: Recent research into the Sparc fusion reactor design make it seem likely to work. Unlike some other fusion reactor designs, Sparc uses high-temperature superconductors which are capable of much stronger magnetic fields in a more closely-confined location. Sparc will be much smaller than large-scale international project ITER, which after multiple delays is now not scheduled to even start fusion reactions by 2035 at the earliest. The Sparc researchers hope that their reactor design will be completed soon enough to have an impact on climate change. The new research on Sparc consists of seven different papers, all of which have favorable estimates for the likelihood of the project succeeding. Some physicists, including Cary Forest, at the University of Wisconsin, were more skeptical. Forest told the New York Times that Sparc's estimates for when their reactor would be ready were probably off by at least a factor of two. "Reading these papers gives me the sense that they're going to have the controlled thermonuclear fusion plasma that we all dream about," said Cary Forest, a physicist at the University of Wisconsin who is not involved in the project. "But if I were to estimate where they're going to be, I'd give them a factor of two that I give to all my grad students when they say how long something is going to take."

Anthony Boadle, reporting for Reuters: [...] In April and May, so many Manaus residents were dying from COVID-19 that its hospitals collapsed and cemeteries could not dig graves fast enough. The city never imposed a full lockdown. Non-essential businesses were closed but many simply ignored social distancing guidelines. Then in June, deaths unexpectedly plummeted. Public health experts wondered whether so many residents had caught the virus that it had run out of new people to infect. Research posted last week to medRxiv, a website distributing unpublished papers on health science, estimated that 44% to 66% of the Manaus population was infected between the peak in mid-May and August.

The study by the University of Sao Paulo's Institute of Tropical Medicine tested newly donated banked blood for antibodies to the virus and used a mathematical model to estimate contagion levels. The high infection rate suggested that herd immunity led to the dramatic drop in cases and deaths, the study said. Scientists estimate that up to 70 pct of the population may need to be protected against coronavirus to reach herd immunity. In Manaus, daily burials and cremations fell from a peak of 277 on May 1 to just 45 in mid-September, the mayor's office said. The COVID-19 death toll that officially peaked at 60 on April 30 dropped to just two or three a day by late August. Now the numbers are on the rise again.

The existence of liquid water on Mars -- one of the more hotly debated matters about our cold, red neighbor -- is looking increasingly likely. From a report: New research published Monday in the journal Nature Astronomy indicates there really is a buried reservoir of super-salty water near the south pole of the planet. Scientists say such a lake would significantly improve the likelihood that the red planet just might harbor microscopic life of its own. Some scientists remain unconvinced that what's been seen is liquid water, but the latest study adds weight to a tentative 2018 finding from radar maps of the planet's crust made by the Mars Express robot orbiter. That research suggested an underground "lake" of liquid water had pooled beneath frozen layers of sediment near the Martian south pole -- akin to the subglacial lakes detected beneath the Antarctic and the Greenland ice sheets on Earth.

Earth's subglacial lakes are teeming with bacterial life, and similar life might survive in liquid reservoirs on Mars, scientists have speculated. "We are much more confident now," said Elena Pettinelli, a professor of geophysics at Italy's Roma Tre University, who led the latest research and the earlier study. "We did many more observations, and we processed the data completely differently." The planetary scientist and her team processed 134 observations of the region near the south pole with ground-penetrating radar from the Mars Express Orbiter between 2012 until 2019 -- more than four times as many as before, and covering a period of time more than twice as long. They then applied a new technique to the observation data that has been used to find lakes beneath the Antarctic ice sheet, as well as an older technique used in the 2018 study. Both methods indicate there is a "patchwork" of buried reservoirs of liquid in the region, Pettinelli said -- a large reservoir about 15 miles across, surrounded by several smaller patches up to 6 miles across.

Forget artificial sweeteners. Researchers are now developing new forms of real sugar, to deliver sweetness with fewer calories. But tricking our biology is no easy feat. From a report: Until the late eighteenth century, when sugar production started to become mechanized, most people consumed very little of what nutritionists call "free" or "added" sugars -- sweeteners other than, say, the lactose naturally present in milk and the fructose naturally present in fruit. In 1800, an average American would have lived and died never having encountered a single manufactured candy, let alone the array of sugar-sweetened yogurts, snacks, sauces, dressings, cereals, and drinks that now line supermarket shelves. Today, that average American ingests more than nineteen teaspoons of added sugar every day. Not only does most of that never come into contact with our taste buds; our sweet receptors are also less effective than those for other tastes. Our tongues can detect bitterness at concentrations as low as a few parts per million, but, for a glass of water to taste sweet, we have to add nearly a teaspoon of sugar. DouxMatok's method of restructuring sugar crystals was invented by Baniel's father, Avraham, an industrial chemist. He patented the technique five years ago, when he was ninety-six; today, at the age of a hundred and one, he has finally retired. At one point during my visit, Eran sifted through a pile of his father's memorabilia -- black-and-white photographs, identification cards, university certificates -- to find illustrations for a forthcoming presentation about the company.

Many of the photographs were new to Eran, and, as he tried to place them, the outline of his father's life emerged: a six-year-old Polish boy sent to boarding school in what was then the British Palestine Mandate; a student at the University of Montpellier; a promising young scientist, strikingly handsome, exempted from serving in the British Army's Palestine Regiment so that he could make bombs in the basement of a paint factory near Haifa. [...] Estella Belfer, a pastry chef who is a judge on the TV show "Bake-Off Israel," hopes to use Incredo exclusively one day, but, recently, she told me about some of the challenges of cooking with it. "To make chocolate, it's easy. I just substitute the sugar with a smaller amount. In shortbread cookies, it is an improvement -- it makes them crispier," she said. "But in the cupcakes and the sponge cakes -- this is where there is an art to using Incredo sugar." Sugar is responsible for much of the tender, springy texture of a good cake; Incredo sugar behaves exactly the same way, but there's a lot less of it, which creates a problem. Belfer told me that she has successfully blended other ingredients, including soluble fibre and plant proteins, to restore the missing bulk and fluffiness -- "but it's not easy."

Long-time Slashdot reader fahrbot-bot quotes Quanta magazine: It was an old idea of Stephen Hawking's: Unseen "primordial" black holes might be the hidden dark matter. It fell out of favor for decades, but a new series of studies has shown how the theory can work...

Their very blackness makes it hard to estimate how many black holes inhabit the cosmos and how big they are. So it was a genuine surprise when the first gravitational waves thrummed through detectors at the Laser Interferometer Gravitational-Wave Observatory (LIGO) in September 2015. Previously, the largest star-size black holes had topped out at around 20 times the mass of the sun. These new ones were about 30 solar masses each — not inconceivable, but odd. Moreover, once LIGO turned on and immediately started hearing these sorts of objects merge with each other, astrophysicists realized that there must be more black holes lurking out there than they had thought. Maybe a lot more.

The discovery of these strange specimens breathed new life into an old idea — one that had, in recent years, been relegated to the fringe. We know that dying stars can make black holes. But perhaps black holes were also born during the Big Bang itself. A hidden population of such "primordial" black holes could conceivably constitute dark matter, a hidden thumb on the cosmic scale...

Following a flurry of recent papers, the primordial black hole idea appears to have come back to life. In one of the latest, published last week in the Journal of Cosmology and Astroparticle Physics, Karsten Jedamzik, a cosmologist at the University of Montpellier, showed how a large population of primordial black holes could result in collisions that perfectly match what LIGO observes. "If his results are correct — and it seems to be a careful calculation he's done — that would put the last nail in the coffin of our own calculation," said Ali-Haïmoud, who has continued to play with the primordial black hole idea in subsequent papers too. "It would mean that in fact they could be all the dark matter."

"It's exciting," said Christian Byrnes, a cosmologist at the University of Sussex who helped inspire some of Jedamzik's arguments. "He's gone further than anyone has gone before...." And with every subsequent observing run, LIGO has increased its sensitivity, allowing it to eventually either find such small black holes or set strict limits on how many can exist. "This is not one of these stories like string theory, where in a decade or three decades we might still be discussing if it's correct," Byrnes said.

An anonymous reader quotes Teslarati: On August 19th this year, astronomers using the Panoramic Survey Telescope and Rapid Response System observatory in Hawaii spotted an object destined to enter Earth orbit this fall. Designated as object 2020 SO, the item is now believed to be a rocket booster from NASA's Surveyor 2 mission which crash landed on the Moon in 1966 during the Apollo-era of the Cold War's space race.

"I suspect this newly discovered object 2020 SO to be an old rocket booster because it is following an orbit about the Sun that is extremely similar to Earth's, nearly circular, in the same plane, and only slightly farther away the Sun at its farthest point," Dr. Paul Chodas, the director of NASA's Center for Near Earth Object Studies, explained in comments to CNN.

"That's precisely the kind of orbit that a rocket stage separated from a lunar mission would follow, once it passes by the Moon and escapes into orbit about the Sun. It's unlikely that an asteroid could have evolved into an orbit like this, but not impossible," he said. This specific type of event has only happened once before, namely in 2002 with a Saturn V upper stage from Apollo 12, according to Dr. Chodas.

University of California at Berkeley has made a big announcement: Transistors based on carbon rather than silicon could potentially boost computers' speed and cut their power consumption more than a thousandfold — think of a mobile phone that holds its charge for months — but the set of tools needed to build working carbon circuits has remained incomplete until now.

A team of chemists and physicists at the University of California, Berkeley, has finally created the last tool in the toolbox, a metallic wire made entirely of carbon, setting the stage for a ramp-up in research to build carbon-based transistors and, ultimately, computers.

"Staying within the same material, within the realm of carbon-based materials, is what brings this technology together now," said Felix Fischer, UC Berkeley professor of chemistry, noting that the ability to make all circuit elements from the same material makes fabrication easier. "That has been one of the key things that has been missing in the big picture of an all-carbon-based integrated circuit architecture."
Heat was used to induce the molecules to join together, in a process Fischer compares to an atomic-scale set of Legos. "They are all precisely engineered so that there is only one way they can fit together. It's as if you take a bag of Legos, and you shake it, and out comes a fully assembled car. That is the magic of controlling the self-assembly with chemistry..."

"I believe this technology will revolutionize how we build integrated circuits in the future..." Fischer said.
