- Deregulation at heart of Japan's new robotics revolution
By Sophie Knight and Kaori Kaneko TOKYO (Reuters) - Neurosurgeon Tetsuya Goto had just begun testing a robot to perform brain surgery when he discovered Japan was moving to tighten regulations that would shut down his seven-year project. Over the next dozen years he watched in frustration as the da Vinci, a rival endoscopic robot that U.S. regulators had already approved, became a commercial success while his and other Japanese prototypes languished in laboratories. ...
- 'Star-gazing' shrimp discovered in South Africa JOHANNESBURG (Reuters) - A tiny shrimp equipped with large, candy-striped eyes to ward off predators has been discovered in South African waters, the University of Cape Town said on Friday. The 10-15 mm-long crustacean has been christened the "star-gazer mysid" as its eyes seem to gaze permanently upwards. Similar to insects' eyes, they each look in a different direction. "The vivid ringed patterns are thought to be there to make the eyes appear to belong to a much bigger creature, and hence to scare off predators," the university said. ...
- Banking culture breeds dishonesty, scientific study finds By Kate Kelland LONDON (Reuters) - - A banking culture that implicitly puts financial gain above all else fuels greed and dishonesty and makes bankers more likely to cheat, according to the findings of a scientific study. Researchers in Switzerland studied bank workers and other professionals in experiments in which they won more money if they cheated, and found that bankers were more dishonest when they were made particularly aware of their professional role. ...
- Want to live on the 'roof of the world'? Grow barley
By Will Dunham WASHINGTON (Reuters) - The Tibetan Plateau, the harsh Asian domain known as the 'roof of the world,' would not seem an ideal place for people to call home thanks to its extreme altitude, frigid temperatures, relentless winds and low-oxygen conditions. When people did succeed in colonizing this remote land, it was only after they discovered how to feed themselves year-round with cold-hardy crops like barley brought to the region from far away, scientists said on Thursday. ...
- HIV drugs show promise in treating common eye disease
By Will Dunham WASHINGTON (Reuters) - A class of drugs used for three decades by people infected with the virus that causes AIDS may be effective in treating a leading cause of blindness among the elderly. HIV drugs called nucleoside reverse transcriptase inhibitors (NRTIs), including AZT and three others, blocked age-related macular degeneration in mice and worked well in experiments involving human retinal cells in the laboratory, researchers said on Thursday. In HIV-infected people, NRTIs block an enzyme the virus uses to create more copies of itself. ...
- Ancient Egyptian Handbook of Spells Deciphered Researchers have deciphered an ancient Egyptian handbook, revealing a series of invocations and spells. "It is a complete 20-page parchment codex, containing the handbook of a ritual practitioner," write Malcolm Choat and Iain Gardner, who are professors in Australia at Macquarie University and the University of Sydney, respectively, in their book, "A Coptic Handbook of Ritual Power" (Brepols, 2014).
- Ship Traffic Increases Dramatically, to Oceans' Detriment
The demand for global trade is driving huge growth in ship traffic in the world's oceans, with four times as many ships at sea now than in 1992, a new study reports. The study also found evidence of illegal fishing in protected marine areas, such as ships plying waters around the Kerguelen Islands Marine Reserve in the Southern Indian Ocean, said study author Jean Tournadre, an oceanographer at IFREMER, the French Institute for Marine Research in Plouzane. "I was surprised to see that in 20 years, the growth is almost fourfold, or almost four times larger," Tournadre said. The biggest increase in ship traffic between 1992 and 2012 was along popular shipping lanes in the Indian Ocean and the Chinese seas.
- Marijuana Use Linked to Changes in the Brain Using marijuana daily for four years or longer may be related to certain changes in the brain, according to new research. The investigators found that the people who had been smoking marijuana daily for at least four years had a smaller volume of gray matter in a region called the orbitofrontal cortex, which is commonly associated with addiction. "We found that there … not only is a change in structure, but there also tends to be a change reflected in the connectivity," said study author Francesca Filbey, an associate professor in the School of Behavioral and Brain Sciences at the University of Texas at Dallas. The lost brain volume could explain the increased connectivity found in marijuana users' brains, Filbey told Live Science.
- New Space Station Crew Launches Today: Watch Live
A new three-person crew is launching to the International Space Station atop a Russian rocket today (Nov. 23), and you can watch the liftoff live online. NASA astronaut Terry Virts, European Space Agency astronaut Samantha Cristoforetti and cosmonaut Anton Shkaplerov are scheduled to launch to the space station aboard a Russian Soyuz spacecraft from the Baikonur Cosmodrome in Kazakhstan at 4:01 p.m. EST (2101 GMT) on Nov. 23. You can watch the launch live on Space.com starting at 3 p.m. EST (2000 GMT) via NASA TV. NASA will also air live coverage of the Soyuz as it docks to the space station at 9:53 p.m. EST (0253 Nov. 24 GMT), with coverage beginning at 9:15 p.m. EST (0215 Nov. 24 GMT).
- Gemini Spacecraft Lands at Auction, Escapes Parking Ticket
The 9.5-foot-tall (3-meter) Gemini spacecraft, which was part of RR Auction's week-long space sale that ended on Thursday (Nov. 20), narrowly escaped officers giving it a ticket when it was parked in a loading zone outside the Boston auction house's salesroom on Sunday. "I had to talk my way out of a parking ticket!" wrote Bobby Livingston, RR Auction's executive vice president, in an e-mail to collectSPACE.com. Parking citations aside, the two-ton artifact is an example of a "boilerplate" — metal, none-functioning capsules built to the same size and shape as the spacecraft they were designed to test. According to Livingston, this particular Gemini boilerplate was originally used for tests supporting the recovery of the Gemini capsules after they returned from orbit to a splash down in the ocean.
- Small Volcanic Eruptions Slow Global Warming
Small volcanic eruptions account for part of the global warming slowdown since 2000, a new study suggests. Until now, the climate impacts of small volcanic blasts were overlooked because their planet-cooling particles cluster below the reach of satellites, scientists reported Oct. 31 in the journal Geophysical Research Letters. The stratosphere is the second layer of Earth's atmosphere, above the one in which humans live (the troposphere). Closer to the polar regions, the boundary drops to about 6 miles (10 km), said lead study author David Ridley, an atmospheric scientist at MIT.
- Obama plugs science, math education at ceremony
WASHINGTON (AP) — President Barack Obama said Thursday that 19 scientists, researchers and innovators who received the country's highest honor for their life-changing work embody the spirit of the nation and its "sense that we push against limits and that we're not afraid to ask questions."
- Parallel Worlds Could Explain Wacky Quantum Physics
The idea that an infinite number of parallel worlds could exist alongside our own is hard to wrap the mind around, but a version of this so-called Many Worlds theory could provide an answer to the controversial idea of quantum mechanics and its many different interpretations. Bill Poirier, a professor of physics at Texas Tech University in Lubbock, proposed a theory that not only assumes parallel worlds exist, but also says their interaction can explain all the quantum mechanics "weirdness" in the observable universe. Poirier first published the idea four years ago, but other physicists have recently started building on the idea and have demonstrated that it is mathematically possible. Quantum mechanics is the branch of physics that describes the rules that govern the universe on the microscopic scale.
- CERN scientists discover 2 new subatomic particles GENEVA (AP) — Scientists at the world's largest smasher said Wednesday they have discovered two new subatomic particles never seen before that could widen our understanding of the universe.
- Israeli XPrize Mission Science Twist: Map Lunar Magnetism (Op-Ed)
With the goal of landing the first Israeli spacecraft on the moon, nonprofit SpaceIL is competing for the Google Lunar XPrize: a modern race to the moon. First, instead of developing a rover to drive 500 m like most other teams, SpaceIL engineers are pursuing a "hop" — using the spacecraft's propulsion system first to land, and second to take off again and land 500 m away. Second, we are using the mission not only to stimulate technological advancement, but also to investigate the lunar magnetic field: To that aim, SpaceIL will be carrying a scientific experiment that will advance humanity's shared understanding of the moon. Although magnetized rocks were discovered decades ago, and astronauts returned some samples to Earth for research, the origin of the magnetic field presents an enigma — and an opportunity.
- NASA Pluto Probe to Wake From Hibernation Next Month
NASA's New Horizons probe is about to wake up from a long slumber and get ready for its highly anticipated Pluto flyby next summer. New Horizons is scheduled to emerge from a 99-day hibernation on Dec. 6, then gear up for a six-month Pluto encounter that peaks with the first-ever close flyby of the mysterious dwarf planet on July 14, 2015. “New Horizons is healthy and cruising quietly through deep space, nearly 3 billion miles [4.8 billion kilometers] from home, but its rest is nearly over," Alice Bowman, New Horizons mission operations manager at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, said in a statement. New Horizons launched in January 2006.
- Scientists 'confident' comet lander will wake up BERLIN (AP) — A burst of sunshine in the spring could be just the wakeup call for Europe's comet lander.
- Big Bang's Echo May Reveal Skeleton of the Universe
Scientists may soon get a look at the universe's skeleton by taking a close look at light left over from the Big Bang, which can be used to reveal the presence of matter like stars, galaxies, black holes and even larger structures in the otherwise empty universe. In a similar way, scientists with the international POLARBEAR collaboration want to use a diffuse light that fills every corner of the cosmos to indicate where there is matter and where there is none. POLARBEAR studies the cosmic microwave background (CMB) — the surviving light from the infant universe that is normally seen a kind of baby picture of the cosmos. "We're using the light that we've usually used to measure the seeds of the structure of the universe, to measure the whole tree," said Adrian Lee, a professor of physics at the University of California Berkeley, and a lead scientist with POLARBEAR.
- Famed Physicist Ernest Rutherford Helped Pioneer Sonar in Secret
Ernest Rutherford is best-known for splitting the atom, but that's not his only claim to fame. The British physicist also helped pave the way for sonar technology. Rutherford produced a secret report during World War I that would form the basis for acoustic technology to detect German U-boats, which were a menace to the British Navy and merchant vessels. Now known as the father of nuclear physics, Rutherford became the first person to split an atom in 1917 in a reaction between nitrogen and alpha particles.

- Alien Life Could Thrive on 'Supercritical' CO2 Instead of Water
Alien life might flourish on an exotic kind of carbon dioxide, researchers say. This "supercritical" carbon dioxide, which has features of both liquids and gases, could be key to extraterrestrial organisms much as water is to biology on Earth. Most familiar as a greenhouse gas that traps heat, helping warm the planet, carbon dioxide is exhaled by animals and used by plants in photosynthesis. While it can exist as a solid, liquid and gas, past a critical point of combined temperature and pressure, carbon dioxide can enter a "supercritical" state.
- Space scientist apologizes for shirt called sexist
BERLIN (AP) — British physicist Matt Taylor brimmed with excitement as the European Space Agency's Philae lander successfully separated from the Rosetta spacecraft, showing off a colorful tattoo on his thigh of both, while proclaiming "we're making history."
- 'Nature's Fury': NYC Exhibit Explores Science of Natural Disasters
From the eruption that buried Pompeii in A.D. 79 to the superstorm that shut down New York City in 2012, natural disasters are an unavoidable part of life on Earth. A new exhibit at the American Museum of Natural History (AMNH) explores the causes and aftermath of the mighty forces that shape the planet, from earthquakes to volcanoes to hurricanes. The interactive exhibit lets visitors build their own virtual volcano, create and measure tiny earthquakes, and see what the eye of a tornado looks like. "Nature's Fury: The Science Behind Natural Disasters" will be open to the public from Nov. 15 to Aug. 9, 2015.
- Professor sues Caltech over her disclosures to FBI
PASADENA, Calif. (AP) — A physics professor at the California Institute of Technology sued the school Thursday, claiming she faced a "merciless campaign" of retaliation for telling the FBI that she suspected illegal activities at the university-managed NASA Jet Propulsion Laboratory.
- Global Warming Will Bring More US Lightning Strikes A 50 percent increase in the number of lightning strikes within the United States can be expected by 2100 if temperatures continue to rise due to greenhouse gas emissions, a new study claims. Romps and his colleagues discovered a new combination of two factors that they say predicts 77 percent of the geographic and time patterns seen in U.S.
- Scientists: US-China pact won't slow warming much
- World's Oldest Living People Have Their Genomes Sequenced
Many of these so-called "supercentenarians" were physically and cognitively fit into their old age — one participant practiced as a doctor until age 103, and another drove a car until age 107. The ultimate goal of the research is to figure out how supercentenarians are able to "slow down the aging clock," said study co-author Stuart Kim, a professor of developmental biology at Stanford University. None of the supercentenarians in the study had heart disease, stroke or diabetes — diseases that are very common in old age — and just one participant had been diagnosed with cancer. "The best way forward is for people to pool their data so we can compare all the supercentenarians," Kim said.
- Scientists scour the genomes of people who live past 110
By Will Dunham WASHINGTON (Reuters) - How do some people live past 110 years old? Is it superior genes, clean living, good luck or some combination of those? Scientists studying these "supercentenarians" said on Wednesday they sequenced the genomes of 17 people ages 110 to 116 to try to determine whether they possess genetic traits that may account for their membership in this exclusive club that worldwide includes only about 75 individuals, nearly all women. ...
- L'Aquila Earthquake Scientists Win Manslaughter Appeal
The Italian scientists convicted of manslaughter for failing to sufficiently warn the public before the deadly 2009 L'Aquila earthquake won an appeal of their conviction Monday (Nov. 10). An appeals court in L'Aquila overturned the 2012 convictions and completely cleared the six scientists, according to the Associated Press. The men were members of an official commission convened to evaluate the threat from tremors that had rocked L'Aquila for months before a magnitude-6.3 quake killed 309 people on April 6, 2009. Prosecutors said reassuring statements from the official, Bernardo De Bernardinis, convinced L'Aquila residents to sleep indoors the night of the earthquake, which increased the number of people who died in collapsed buildings.
- Scientists find rare burial site of Ice Age infant in Alaska
By Daniel Wallis (Reuters) - Archaeologists working in Alaska's remote interior have discovered the burial site of an Ice Age infant and a late-term fetus believed to be the youngest remains found in the Americas dating from that period. The burials, found underneath the cremated remains of an Ice Age toddler, date to about 11,500 years ago and provide new insights into mortuary practices of the people who lived in the area of the Upward Sun River site at the time. ...
- GMO battles over 'settled' science spur new study of crops
By Carey Gillam (Reuters) - Monsanto Co, the world's largest seed company, and its brethren of global biotech crop developers are spreading the word that as far as the safety of their genetically modified grain goes, the science is solidly on their side. The message of "settled" science has become the rallying cry for defenders of the crops and food commonly referred to as GMOs as they push back against consumers, environmentalists, lawmakers and others who want the crops labeled, restricted or banned. ...
- Will Purr for Treats: How Cats Became Domesticated A new study has revealed the genetic changes that make kitties snuggle up with humans and purr for treats. Many of the changes have altered the cat's motivation to seek rewards and have changed their fear of new situations, said study co-author Wesley Warren, a geneticist at the Genome Institute at the Washington University School of Medicine in St. Louis. The team also discovered the genetic changes that make cats keen nighttime hunters and why their noses aren't as sensitive as their canine cousins'. Cats and humans go way back: Some studies suggest cats were first domesticated about 9,000 years ago in the Near East, while others trace cat domestication back to China around 5,000 years ago.
- The Science of 'Interstellar': Black Holes, Wormholes and Space Travel
The sci-fi epic "Interstellar" is just a movie, but it throws a lot of science on the screen for space geeks to sink their teeth into. "Interstellar," which opened in theaters across the United States on Friday (Nov. 7), delves into black holes and wormholes, and it touches down on more than one alien planet. Here's a look at some of the space-science concepts that play key roles in the film, which was directed by Christopher Nolan and stars Matthew McConaughey, Anne Hathaway, Jessica Chastain and Michael Caine. "Interstellar" is set at some nebulous point in the not-too-distant future, when global crop failures threaten humanity with extinction.
- Study: Global warming worsening watery dead zones
WASHINGTON (AP) — Global warming is likely playing a bigger role than previously thought in dead zones in oceans, lakes and rivers around the world and it's only going to get worse, according to a new study.
- Breakthrough Prizes in science, math earn winners $3 million each
By Sarah McBride SAN FRANCISCO (Reuters) - Academia doesn't usually bring rich financial rewards. But that changed Sunday for recipients of a record 12 Breakthrough Prizes, the award created two years ago by Russian billionaire venture capitalist Yuri Milner, Facebook founder Mark Zuckerberg, Google co-founder Sergey Brin and other tech industry luminaries. Each prize is worth $3 million, almost three times the cash a Nobel Prize winner receives. This year is the first to honor mathematicians. Five won for work ranging from algebraic geometry to analytic number theory. ...
- Why a Physics Revolution Might Be on Its Way The field of physics may be turned on its head soon, said renowned physicist Nima Arkani-Hamed during a live lecture from the Perimeter Institute for Theoretical Physics in Waterloo, Canada. The problem is that in some sense, the principles behind these theories seem to be impossible when physicists dig a little deeper into them, Arkani-Hamed said. The two ideas are also incredibly constraining, and they make it challenging for physicists to think outside the box and develop new ideas and theories, Arkani-Hamed said.
- Scientist hopes to unlock Ebola's secrets at outbreak's source
By Julie Steenhuysen CHICAGO (Reuters) - Etienne Simon-Loriere of the Pasteur Institut in Paris has his fingers crossed. He is heading to West Africa on Sunday to inspect blood samples gathered from Ebola patients in Guinea in hopes of tracing the path of the virus in the country where the current outbreak began. Such samples are scarce and precious. So far, only a few scientists have them, and many more say they need them in order to do critical research on the virus. ...
- First-Ever Comet Landing Next Week to Be Truly Epic, Scientists Say
The European Space Agency's Rosetta spacecraft is just days away from releasing its Philae lander down to the surface of Comet 67P/Churyumov-Gerasimenko, and scientists working with the mission can feel the anticipation building for the Nov. 12 landing. The small Philae lander — named for an obelisk found on an island in the Nile River in Egypt — is designed to study the surface of the comet. Meanwhile, the Rosetta probe will study Comet 67P/C-G from orbit. Rosetta should release Philae when the two spacecraft are flying about 14 miles (22.5 kilometers) from the center of Comet 67P/C-G. European Space Agency officials will have to wait for 7 to 10 hours before finding out if the landing was successful.
- Passing comet peppered Mars with shooting stars, scientists say
By Irene Klotz CAPE CANAVERAL (Reuters) - The comet that sailed by Mars last month spawned thousands of shooting stars per hour and created a new layer of ionized particles high in the planet’s atmosphere, NASA scientists said on Friday. At twilight, the Martian skies likely took on a yellowish hue from sodium in vaporized comet dust, creating a glow similar to sodium vapor lights commonly used in parking lots on Earth. ...
- Scientists gear up to land 1st spacecraft on comet
BERLIN (AP) — The European Space Agency is making final preparations to land the first unmanned spacecraft on a comet next week, and scientists are hoping that technology designed a quarter century ago will perform as planned.
