Stephen Hawking Warns of Planetary Doom (Again)

Stephen Hawking has once again warned that humanity could wipe itself out before it has a chance to establish far-flung space colonies. At a recent talk in England, the famed physicist singled out nuclear war, genetically engineered viruses and global warming as likely culprits. According to Hawking, the odds of a planetary disaster in the next millennia are high.

Transgenic mosquito ready to join Brazil's war on Zika virus

By Anthony Boadle BRASILIA (Reuters) - A genetically modified mosquito has helped reduce the proliferation of mosquitoes spreading Zika and other dangerous viruses in Brazil, its developers said on Tuesday. The self-limiting strain of the Aedes aegypti mosquito was developed by Oxitec, the U.K.-subsidiary of U.S. synthetic biology company Intrexon. Oxitec, which produces the mosquitoes in Campinas, announced it will build a second facility in nearby Piracicaba, Sao Paulo state, following strong results there in controlling the population of the Aedes vector that also carries the dengue virus.

Last year was hottest on record globally: U.S. science agencies

By Valerie Volcovici WASHINGTON (Reuters) - Last year's global average temperature was the hottest ever by the widest margin on record, two U.S. government agencies said on Wednesday, adding to pressure for deep greenhouse gas emissions cuts scientists say are needed to arrest warming that is disrupting the global climate. Data from U.S. space agency NASA and the National Oceanic and Atmospheric Administration showed that in 2015, the average temperature across global land and ocean surfaces was 1.62 degrees Fahrenheit (0.90 Celsius) above the 20th century average, surpassing 2014's previous record by 0.29 F (0.16 C). This was the fourth time a global temperature record has been set this century, the agencies said in a summary of their annual report.  "2015 was remarkable even in the context of the larger, long-term warming trend," said Gavin Schmidt, director of NASA's Goddard Institute for Space Studies.

Sorry, Spider-Man! You're Too Big to Scale That Wall

Like spiders, a variety of critters can scurry up walls, including some species of cockroach, lizard and beetle. "If a human, for example, wanted to walk up a wall the way a gecko does, we'd need impractically large, sticky feet — our shoes would need to be a European size 145 or a U.S. size 114," study senior author Walter Federle, a professor in the Department of Zoology at the University of Cambridge in the United Kingdom, said in a statement. In fact, humans would need adhesive pads covering 40 percent of their body, or about 80 percent of their front, in order to climb up a vertical wall, the researchers said.

Hundreds of Tiny Bugs Are Probably Hiding in Your Home

Entomologists from North Carolina State University conducted an investigation to find out just how many different arthropods — insects, spiders and other invertebrates that have segmented bodies and jointed legs — might share homes with people. Many arthropod species — like termites, bedbugs and roaches — are known to live alongside humans, and to seek out these living spaces, generally bringing a measure of discomfort and inconvenience to their hosts. The researchers visited and sampled homes within a 30-mile (48 kilometers) radius of Raleigh, North Carolina, collecting any living or dead arthropod that they found in attics, basements, bathrooms, kitchens, bedrooms and common areas.

Raging Fires in Australia Visible from Space

Australia rang in the new year with dangerous tidings: Parts of Western Australia have been battling large bushfires since the beginning of the month. The blazes seem to be easing off, but an Earth-observing satellite captured a dramatic view of the fires earlier this month, showing thick clouds of smoke hugging the nation's southwestern coast. Last week, NASA's Earth Observatory posted a photo taken Jan. 7 by the Suomi NPP satellite's Visible Infrared Imaging Radiometer Suite (VIIRS).

In global warming bets, record 2015 heat buoys mainstream science

By Alister Doyle OSLO (Reuters) - For British climate expert Chris Hope, new data showing that 2015 was the hottest year ever recorded is not just confirmation he's been right all along that the planet is getting warmer. It also won the Cambridge University researcher a 2,000 pound sterling ($2,830) wager made five years ago against a pair of scientists who reject man-made global warming and bet Hope that the Earth would be cooling by now. NASA, the U.S. National Oceanic and Atmospheric Administration (NOAA) and the British Met Office said on Wednesday that 2015 was the warmest year recorded since 1880, boosted by a long-term build-up of greenhouse gases and a natural El Nino event warming the Pacific Ocean.

Russian space agency scales back plans as crisis shrinks budget

By Dmitry Solovyov MOSCOW (Reuters) - Russia will spend 30 percent less on its space program in the next decade and scale back a slew of projects to save money in the face of tanking oil prices and a falling rouble, a plan presented by the country's space agency showed on Wednesday, According to the blueprint, presented to Russian media by Igor Komarov, head of space agency Roscosmos, the space program budget for 2016-2025 will be cut to 1.4 trillion roubles ($17.36 billion), down from 2 trillion roubles. "Russia is certain to implement this project, but at the moment the launch of a booster rocket with a reusable first stage is not economically viable," local media cited Komarov as saying. Russia's Cold War-era rival, the United States, has already successfully tested similar vehicles.

Researchers find possible ninth planet beyond Neptune

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - The solar system may host a ninth planet that is about 10 times bigger than Earth and orbiting far beyond Neptune, according to research published on Wednesday. Computer simulations show that the mystery planet, if it exists, would orbit about 20 times farther away from the sun than Earth, said astronomers with the California Institute of Technology in Pasadena. "It's a pretty substantial chunk of our solar system that's still out there to be found, which is pretty exciting," astronomer Mike Brown said in a statement.

Oldest Animal Jonathan the Tortoise Is Going Strong at 183

A caloric increase is helping the oldest known living terrestrial animal in the world — a giant tortoise — reclaim his health and vigor, a veterinarian reports. At 183 years old, Jonathan, who resides on the tiny Atlantic island of St. Helena, is now eating like a king. Before the diet change, Jonathan's keratin beak was blunt and soft, making him an inefficient grazer, Dr. Joe Hollins, the veterinarian who cares for Jonathan, said in a 2012 report in the journal Veterinary Record.

Fowl Play: Diverse Parasites Infest Backyard Chickens

Chickens that live in backyards are exposed to a wider range of ectoparasites — parasites that live on the skin — than their commercial counterparts. In a study published online Jan. 11 in the Journal of Medical Entomology, scientists investigated 100 hens from 20 flocks in Southern California, and found a number of parasites in the coops and on the birds that are typically absent in commercial farms. Many of the urban chickens were playing host to a diverse group of parasites, which included fleas, mites and six species of lice: Menopon gallinae, Menacanthus cornutus, Menacanthus stramineus, Goniocotes gallinae, Lipeurus caponis and Cuclotogaster heterographus.

Warmer Indian Ocean could be 'ecological desert', scientists warn

By Amantha Perera NEGOMBO, Sri Lanka (Thomson Reuters Foundation) - Anslem Silva has fished for four decades from this popular harbor on Sri Lanka's west coast, but for five years now filling his boat has become increasingly difficult. Overfishing is responsible for some of the lowered catch, but another problem may also be contributing: lack of food for the fish themselves, driven by global warming. "Rapid warming in the Indian Ocean is playing an important role in reducing phytoplankton up to 20 percent," said Roxy Mathew Koll, a scientist at the Centre for Climate Change Research at the Indian Institute of Tropical Meteorology in Pune.

Red, Dead Galaxies Are Also LIERs, Scientists Say

Many galaxies are LIERS, says Francesco Belfiore, a graduate student at the Kavli Institute for Cosmology at the University of Cambridge. Earth lies in a galaxy that is flush with new star birth. In trying to study the chemistry of these "dead" galaxies, researchers have found a different chemical fingerprint than the one that dominates star-forming galaxies.

Poor Sleep Tied to Hardened Brain Arteries in Older Adults

Older people who sleep poorly may have a slightly increased risk of having hardened blood vessels in the brain, and oxygen-starved brain tissue, according to a new study. Both of these issues may contribute to a greater risk of stroke and cognitive impairment, the researchers said. "The forms of brain injury that we observed are important because they may not only contribute to the risk of stroke but also to chronic progressive cognitive and motor impairment," study author Dr. Andrew Lim, a neurologist and scientist at Sunnybrook Health Sciences Center in Toronto, said in a statement.

Doctors Reflect on 'Surreal' Day of 2013 Asiana Airlines Crash

On July 6, Flight 214 from Incheon International Airport in South Korea crashed just short of the runway at San Francisco International Airport, striking the airport's seawall with its landing gear and tail section. It was San Francisco General that received the most patients of any area hospital that day, and doctors are now reporting their experience in the hopes of helping other hospitals prepare for a similar event. "The day was a surreal experience," said Dr. Rachael Callcut, a surgeon, and the lead author of a new article about the tragedy published today (Jan. 14) in the journal JAMA Surgery.

Self-Filling Water Bottle Converts Humid Air into Drinkable H2O

Kristof Retezár, a designer based in Vienna, invented a device that can extract humidity from the air and condense it into drinkable water. The handy gadget, dubbed Fontus, can be attached to a bike so that cyclists can generate water during long-distance rides through the countryside, where pit stops may be few and far between. Fontus works using the basic principle of condensation, which can be easily demonstrated by taking something out of a refrigerator (for instance, a can of soda) and leaving it on the kitchen counter for a bit.

NASA to Capture Best-Ever Portrait of Coral Reef Health

NASA is about to get up close and personal with Earth's corals: The space agency will use airplanes and water instruments to survey these delicate structures and capture the most detailed views ever of the planet's corals. Corals are crucial to Earth's ecosystem, but they are typically studied only occasionally, during diving expeditions. The new NASA campaign is aptly named CORAL (short for COral Reef Airborne Laboratory), and aims to assess the condition of these vulnerable ecosystems and to collect data on the size and quality of the reefs.

Belgian drone mixes plane and quadcopter technology

By Jim Drury Researchers in Belgium have devised a prototype delivery drone which they say could rival the likes of Amazon Prime Air and Google's Project Wing. The University of Leuven team behind VertiKUL 2 (KUL is the acronym for Katholieke Universiteit Leuven) say the drone combines the ability of quadcopters to take-off and land vertically with both the speed of conventional aircraft and their capacity to fly long distances. Lead researcher Bart Theys told Reuters that combining aspects of multicopters and conventional aircraft created great potential for a future drone delivery service.

SpaceX narrowly missed Falcon 9 rocket landing, video shows

The SpaceX Falcon 9 rocket that exploded into a fiery ball just after landing at sea off California on Sunday had descended with pinpoint accuracy onto an ocean barge before a landing leg buckled, causing the booster to tip over, a landing video showed. Heavy fog at the rocket's launch site in California may have caused condensation to collect in the latching mechanism and then ice it over, said technology entrepreneur Elon Musk, owner and chief executive of Space Exploration Technologies, or SpaceX. SpaceX is seeking to develop a cheap, reusable rocket and a successful ocean landing would have marked a second milestone for the company, a month after it nailed a spaceflight first with a successful ground landing in Florida.
