Lockheed unit to help design quieter supersonic passenger jet: NASA

(Reuters) - NASA on Monday announced a contract award to Lockheed Martin Corp's unit for the preliminary design of a "low boom" flight demonstration aircraft. NASA's Commercial Supersonic Technology Project had asked industry teams to submit design concepts for a test aircraft that can fly at supersonic speeds, creating a supersonic "heartbeat" - a soft thump rather than the disruptive boom currently associated with supersonic flight.

Scientists find Zika increases risk of rare neurological illness

French scientists say they have proved a link between the Zika virus and a nerve syndrome called Guillain-Barre, suggesting countries hit by the Zika epidemic will see a rise in cases of the serious neurological condition. Guillain-Barre (GBS) is a rare syndrome in which the body's immune system attacks part of the nervous system. In a retrospective study analyzing data from a Zika outbreak in French Polynesia during 2013 and 2014, researchers led by Arnaud Fontanet of France's Institut Pasteur calculated the estimated risk of developing Guillain-Barre Syndrome (GBS) at 2.4 for every 10,000 people infected by Zika.

Bill Gates 'Discovers' 14-Year-Old Formula on Climate Change

Bill Gates just released a climate science equation that explains how the world can lower carbon dioxide emissions "down to zero," according to the 2016 edition the annual letter he and his wife, Melinda, published. But instead of grilling Gates about the origins of the formula, climate scientists are glad he's talking about it, said Michael Mann, a distinguished professor of atmospheric science at Pennsylvania State University. The genesis of Gates' equation might remain a mystery for now — the Bill & Melinda Gates Foundation didn't return Live Science's requests for comment.

Easter Island Civilization Not Destroyed by War, New Evidence Shows

Thousands of small, sharp, spearlike objects scattered throughout Easter Island have long been presumed to be evidence of massive warfare that led to the demise of its ancient civilization. Easter Island is a tiny landmass located about 2,300 miles (3,700 kilometers) off the coast of Chile. Polynesians first arrived on the island in the 13th century, and Rapa Nui's early inhabitants were famous for the enormous stone statues (called moai) that they built and placed on the coastline.

Rare Charles Darwin Letter Fails to Sell at Auction

A handwritten letter by famed naturalist Charles Darwin to a British marine biologist was put up for auction yesterday (Feb. 25) but failed to sell, according to Nate D. Sanders Auctions, the Los Angeles-based auction house that arranged the sale. The letter, which was originally listed with a minimum bid of $69,500, was expected to be one of several of Darwin's letters to be auctioned off recently, but the historic document did not end up being sold. Last September, a letter in which Darwin expressed his lack of belief in the Bible sold for a record $197,000, according to Bonhams, the British auction house that arranged the sale in New York.

Funeral Feast? Butchered Turtles in Ancient Grave Hint at Ritual

In an ancient settlement on the banks of the Tigris River in Turkey, archaeologists have made a strange discovery: 17 butchered soft-shelled turtles in the grave of a woman and child. As there are no marks of trauma or injuries, it's not clear how the two people buried with the turtles died.

'Mojoe' on the Go: New Thermos Doubles as Portable Coffeemaker

Hyman first dreamed up what would become the mojoe when he was a college student studying late at night in the library. The mojoe is the first of its kind, Hyman said, because unlike other portable coffeemakers on the market, the mojoe does not require you to heat water before brewing, and it can withstand superhot temperatures. To create a self-contained coffee-brewing system within a travel mug, Hyman and his team figured out how to combine aspects of drip brewing with vacuum brewing in a small, light and durable device.

Physics of Skipping Stones Could Make Bounceable Naval Weapons

"A text titled 'The Art of Shooting [in] Great Ordnaunce' by William Bourne was likely published in 1578, and is the first known account to mention that if cannonballs are fired at a sufficiently low angle they will ricochet across the water surface," said study co-author Tadd Truscott, a fluid dynamicist at Utah State University in Logan. "This bomb was made to spin at a great rate before impact, enabling it to move along the water surface and avoid torpedo nets on its way to destroy key German dams," Truscott told Live Science. "Water impact has been heavily studied for the past 100 years, with motivations ranging from understanding the physics of seaplane landing to, more commonly, a simple desire to better understand the world in which we live," Truscott said.

New Virtual Reality Suit Lets You Reach Out & Touch 'Environment'

Virtual reality could one day incorporate all the senses, creating a rich and immersive experience, but existing virtual reality headsets only simulate things you can see and hear. Designed by Lucian Copeland, Morgan Sinko and Jordan Brooks while they were students at the University of Rochester, in New York, the suit looks something like a bulletproof vest or light armor. In addition, there are small accelerometers embedded in the suit's arms.

Ancient Stubby-Legged Reptiles with Tiny Heads Were World Travelers

Before dinosaurs roamed the planet, tanklike herbivores called pareiasaurs — barrel-chested and stubby-legged turtle relatives — reigned as Earth's first large plant-eaters. With tiny heads and bony knobs studding their skulls and bodies, pareiasaurs wouldn't have won many beauty contests. Pareiasaurs lived during the Permian era, about 266 million to 252 million years ago.

Earth's Early Ocean Was No Scalding Sea

Rocks from the deep past, some 3.5 billion years ago when life first appeared on the planet, were deposited on a deep, cold ocean floor, not in a scalding sea, a new study suggests. "This is the first evidence that over the entire 3.5 billion years, Earth has operated within a temperature range that suits life," said lead study author Maarten de Wit, a professor at Nelson Mandela Metropolitan University in Port Elizabeth, South Africa. To take the temperature of Earth's ancient ocean, the researchers trekked to the Barberton Greenstone Belt in South Africa.

Is the Doomsday Clock Still Relevant?

Last month, experts with the Bulletin of the Atomic Scientists announced that the "Doomsday Clock," an iconic symbol meant to represent humanity's risk of facing global calamity, was stuck at 3 minutes to midnight, despite a historic climate agreement reached in Paris just a few months earlier. As part of their reasoning, the atomic bulletin scientists cited the nonbinding nature of those Paris climate accords, the rise of hostility between superpowers and the proliferation of more "modernized" nuclear weapons that may be more tempting to use. Given that, the Doomsday Clock may not be the right tool to mobilize people to actually change things for the better, experts say.

Virtual reality 'heroin cave' aimed at helping addicts kick habit

By Amanda Orr HOUSTON (Reuters) - Addicts in a new study at the University of Houston will strap on virtual reality headsets and navigate a "heroin cave" to help them try and kick their addictions. The heroin environments, a house party where the drug is snorted and one where it is injected, took nearly a year to complete to ensure realism, its creators said. The study from the University of Houston Graduate College of Social Work uses an eight-camera infrared system that projects life-sized 3D avatars and environments with which participants can interact in a virtual reality chamber known as the "heroin cave." Details from an open pizza box on the back patio to cash tossed on a table next to a cigarette lighter are meant to augment sensations and trigger a heroin craving.

Zika Virus Linked to Stillbirth

A woman in Brazil who became infected with the Zika virus gave birth to a stillborn baby, and large parts of the infant's brain were missing, according to a new report. Moreover, the fetus had damage to tissues outside of the central nervous system, the researchers said. "These finding raise concerns that the virus may cause severe damage to fetuses leading to stillbirths, and may be associated with effects other than those seen in the central nervous system," study author Dr. Albert Ko, chair of the Department of Epidemiology of Microbial Diseases at the Yale School of Public Health, said in a statement.

Gravitational Waves: Did Merging Black Holes Form from Single Star?

Could a single, dying star give birth to not one, but two black holes? Scientists have long held different ideas about how black holes of this size get close enough to collide, but another proposal has just entered the ring: that the black holes were created, shortly before their collision, from one, massive star as it was collapsing in on itself. This new hypothesis posits that the merger of these two black holes would produce light — including, possibly, a burst of gamma-rays, the highest-energy form of light.

Gas from thawing permafrost could add further to global warming, study says

By Ellen Wulfhorst NEW YORK (Thomson Reuters Foundation) - Arctic permafrost that is thawing due to global warming is releasing greenhouse gases, further compounding the problem of climate change, according to a study released on Thursday. As the permafrost thaws, changes in the way its soil microbes function and the soil carbon decomposes add to the emissions of carbon dioxide and methane into the atmosphere, according to the study by U.S. and Chinese scientists.

This could be the implication of a new study on mice revealing that a natural sugar called trehalose prevents a diet high in fructose, or fruit sugar, from causing fatty liver disease. "In general, if you feed a mouse a high-sugar diet, it gets a fatty liver," said Dr. Brian DeBosch, a pediatric gastroenterologist at the Washington University School of Medicine in St. Louis, who led the study. The mice given the trehalose also had lower body weights at the end of the study and lower levels of circulating cholesterol, fatty acids and triglycerides, than the control mice not give the water, DeBosch added.

The Science Behind Hitler's Possible Micropenis 

History buffs know that Adolf Hitler had an undescended testicle, but a new review of his medical records suggests that der Führer also had other genital problems, including a condition called a micropenis. In fact, Hitler had a slew of below-the-belt problems, according to the new book, "Hitler's Last Day: Minute by Minute," (Short Books Ltd, 2015), by historians Jonathan Mayo and Emma Craigie. After reading Hitler's medical records, they said they found evidence that Hitler had a condition called penile hypospadias, in which the opening to the urethra is not at the tip of the penis, but either somewhere along the shaft or at its base, according to news reports.

Male birds have ZZ and females have ZW, and so the gene for blue eggs could be carried on the Z chromosome, the researchers said.

Kinky Spiders: Males Tie Up Partners During Sex

By restraining their partners, male spiders reduce their chances of falling victim to sexual cannibalism, a new study finds. Prior studies described the male spider's unusual mating behavior — wrapping silk around the female's legs before and during copulation — and the scientists wondered if longer legs would help males restrain their hungry mates, leaving the guys more likely to survive cannibalism sparked during the throes of passion. In some insect and spider species, sex can be a deadly roll of the dice for males, carrying the possibility that their female partners may suddenly identify them as a convenient postcoital snack.

Dodo Birds Weren't 'Dodos' After All

Dodos weren't as dumb as their reputation suggests. New research finds that these extinct, flightless birds were likely as smart as modern pigeons, and had a better sense of smell. Dodos (Raphus cucullatus) had gone extinct by 1662, less than 100 years after their island home of Mauritius became a destination for Dutch explorers.

SpaceX set to launch satellite, then try to land rocket on ocean platform

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - A SpaceX Falcon 9 rocket was being readied for launch from Florida on Wednesday on a mission to thrust a European satellite toward orbit and then attempt a return touchdown on an ocean platform, company officials said. The 23-story-tall rocket, carrying a commercial communications satellite for Luxembourg-based SES SA, was scheduled to blast off from Cape Canaveral Air Force Station at 6:46 p.m. EST/2346 GMT. The flight would be the second of more than 12 planned this year by Space Exploration Technologies, the private rocket launch service owned and operated by high-tech entrepreneur Elon Musk.

'Warm Blob' Caused Wild Climate Swings During Last Ice Age

A "warm blob" of surface water played a role in Greenland's wild climate swings during the last ice age, a new study finds. Greenland's climate flipped quickly and brutally from cold to warm and back again 25 times between about 20,000 and 70,000 years ago, ice cores and ocean sediments show. The abrupt climate swings, called Dansgaard-Oeschger events, involved extreme changes in average temperature.

Powerful Laser Could Blast Spacecraft to Mars in 3 Days (Video)

It sounds like science fiction, but it's eminently possible, researchers say: Robotic spacecraft could get to Mars after a journey of just three days. The key to making this happen is photon propulsion, which would use a powerful laser to accelerate spacecraft to relativistic speeds, said Philip Lubin, a physics professor at the University of California, Santa Barbara. "There are recent advances which take this from science fiction to science reality," Lubin said at the 2015 NASA Innovative Advanced Concepts (NIAC) fall symposium last October.

Telescope used on Armstrong's moon landing finds new galaxies

By Pauline Askin SYDNEY (Reuters) - An Australian telescope used to broadcast live vision of man's first steps on the moon in 1969 has found hundreds of new galaxies hidden behind the Milky Way by using an innovative receiver that measures radio waves. Scientists at the Parkes telescope, 355 km (220 miles) west of Sydney, said they had detected 883 galaxies, a third of which had never been seen before. The findings were reported in the latest issue of Astronomical Journal under the title 'The Parkes HI Zone of Avoidance Survey'.

Sexual Spread of Zika May Be More Common than Thought, CDC Warns

Sexual transmission of the Zika virus from men to women may be a more common mode of the virus's spread than researchers previously thought, officials said today. Authorities at the Centers for Disease Control and Prevention (CDC) and several state public health departments are now investigating 14 new reports of possible sexual transmission of Zika virus. All of them involve men in the United States who had recently traveled to places where the virus is actively spreading, and their female sex partners who had not traveled, the CDC announced today (Feb. 23).

Satellite operator SES says interested in used SpaceX rocket

By Irene Klotz PORT CANAVERAL, Fla. (Reuters) - Satellite operator SES SA is interested in buying a used Falcon 9 rocket from Elon Musk’s Space Exploration Technologies, or SpaceX, for a future launch, the chief technology officer for SES said on Tuesday. “SES would have no problem in flying a re-used (rocket’s) first stage. If it’s flight-worthy, we’re happy,” SES’s Martin Halliwell told reporters at a pre-launch news conference.

Are Genetic Weapons the Best Tools to Fight Zika Virus? (Op-Ed)

David O'Brochta has no conflicts of interest regarding the content of this piece. The unexpected risks unborn children appear to face from the Zika virus have drawn renewed attention to the importance of mosquito control in public health, but the Zika outbreak does not necessarily justify the immediate application of new — and relatively untested — mosquito controls. Mosquito control today involves a combination of chemical insecticide applications to kill adults and larvae, natural insecticides produced by Bacillus bacteria and elimination of mosquito habitats such as standing water.
