Bill Nye, Neil deGrasse Tyson Celebrate 35 Years of The Planetary Society

Led by Bill Nye "The Science Guy," with help from astrophysicist Neil deGrasse Tyson, space exploration advocacy organization The Planetary Society recently celebrated its 35th anniversary and the opening of its new headquarters in Pasadena, California. Founded in 1980 by a group of scientists that included famed astronomer and science popularizer Carl Sagan, the nonprofit Planetary Society is "the largest and most influential public space organization group on Earth," according to its website. In 2010, Nye took the job of chief executive officer for the organization.

Newfound Moon Craters Point to Asteroid Puzzle

Newfound lunar craters suggest that asteroids that smashed into the moon long ago were very different from the ones that now occupy the asteroid belt, researchers say. Scientists think swarms of asteroids and comets pummeled Earth, the moon and the other worlds of the inner solar system during an era known as the Late Heavy Bombardment about 4.1 billion to 3.8 billion years ago. The many giant, round craters known as lunar basins that pockmark the moon's surface now stand as mute testimony to this violent time.

NASA must take more care about rocket parts after accident: probe

By Irene Klotz CAPE CANAVERAL, Fla (Reuters) - - Independent NASA accident investigators said the U.S. space agency should "perform a greater level of due diligence for major system components" in rockets that deliver cargo to the International Space Station following a 2014 explosion. The recommendation came in the investigators' report on the explosion of Orbital ATK's Antares rocket that destroyed a load of cargo for the space station. It may spur calls for more oversight of NASA's use of commercial contracts to deliver cargo - and soon crew members - to the space station.

Ultrasonic bubbles give cold water bug-killing cleaning power

By Matthew Stock A hand-held device that infuses a gentle stream of regular cold water with ultrasound to turn it into a highly effective cleaning tool has been developed by British scientists, who say it could reduce dependence on traditional detergents and help combat anti-microbial resistance. The device, known as Starstream, passes a gentle stream of water through a nozzle that generates ultrasound and bubbles.

Giant Wyoming Crack Explained: A Landslide Brought It Down

A gaping crack the length of six football fields that opened up in a matter of one to two weeks in northern Wyoming is likely the product of a landslide, geologists said. A hunter looking for antelope discovered the jagged gash near Ten Sleep, a town in rural Wyoming by the Bighorn Mountains, on Oct. 1, reported 9NEWS, a local CBS channel in Wyoming. "I was stunned," Randy Becker, the hunter with SNS Outfitter and Guides who found the crack, told CBS Denver.

Autumn's Night Skies Offer the Best of Summer ... and Winter

Looking toward the west (to the right in the graphic), you can see the familiar constellations of summer. Above Capricornus, just to the left of Altair, is the tiny constellation Delphinus, the dolphin, one of the few constellations that actually looks like its name. It's worth also exploring the region between Altair and Albireo, where you will find two of the finest deep-sky objects: Brocchi's Cluster, popularly called "the coat hanger," and the Dumbbell Nebula, one of the largest and brightest planetary nebulae.

Sally Ride's Life Shines in New Photobiography Book for Kids

A new children's photobiography of Sally Ride, the first American woman to fly in space, traces the course of her life in pictures and stories compiled by her partner of 27 years — offering a rare opportunity to get to know the famously private astronaut. "Sally Ride: A Photobiography of America's Pioneering Woman in Space" (Roaring Brook Press, 2015) profusely illustrated with photos and artifacts from Ride's life, O'Shaughnessy draws from all those eras to paint a full picture of her, pointing the way for any young person wondering what the life of an astronaut is like and what it takes to become one. Space.com talked with O'Shaughnessy about writing the biography and what she hopes people will take away from Ride's story.

Alan Alda's Challenge: Can you Explain Sound to an 11-Year-Old?

The winning answer will help not only children across the world understand sound, but also the contest's founder, actor Alan Alda. Alda is known for his work on the TV series "M*A*S*H" and "The West Wing," and now heads the Alan Alda Center for Communicating Science at Stony Brook University in New York. In fact, Alda started the competition based on an experience he had at age 11.

Why Do Sand Dune Avalanches Boom, Burp and Sing?

The booming and burping sounds each correspond to different classes of waves within the sand dune, they found. During the investigation, researchers visited Eureka Dunes in Death Valley and Dumont Dunes in the Mojave Desert — or what the researchers called the "very hot and sandy dunes in California" — for a total of 25 summer days, study lead researcher Nathalie Vriend said in a statement. Vriend completed the research while a doctoral student at the California Institute of Technology in Pasadena, but now is a research fellow in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge in England.

Robin Williams' Death: What Is Lewy Body Dementia?

Although actor Robin Williams died by suicide, the underlying cause of his death was a rare brain disease called Lewy body dementia, according to his widow. The disease caused Williams to experience hallucinations and other debilitating neurological symptoms, including depression, Susan Schneider Williams, widow of the late actor, told People magazine in a recent interview. "It was not depression that killed Robin," Schneider Williams said in the interview.

Rare Multistate Outbreaks Cause the Most Foodborne Illness Deaths, CDC Says

The reason that a relatively high proportion of deaths come from this small percentage of outbreaks is that the multistate outbreaks tend to involve more lethal types of bacteria contamination, CDC Director Dr. Tom Frieden said at a news conference today (Nov. 3). "Multistate foodborne disease outbreaks are the most deadly type of foodborne outbreak, despite accounting for only a small portion of reported outbreaks in the United States," Frieden said in a statement. The most recent multistate outbreak involves E. coli contamination in food from Chipotle Mexican Grill.

Anti-Vaccination Websites Use 'Distorted' Science, Researchers Find

Many websites that promote unscientific views about vaccinations use pseudoscience and misinformation to spread the idea that vaccines are dangerous, according to a new study. For example, of the nearly 500 anti-vaccination websites examined in the study, nearly two-thirds claimed that vaccines cause autism, the researchers found. About two-thirds of the websites used information that they represented as scientific evidence, but in fact was not, to support their claims that vaccines are dangerous, and about one-third used people's anecdotes to reinforce those claims, the scientists found.

Acra at Last? Site of Ancient Jewish Revolt Unearthed

Archaeologists in Jerusalem may have just solved one of the city's greatest geographical mysteries. Excavators recently unearthed what they think are the ruins of the Acra, a fortress constructed more than 2,000 years ago by the Greek ruler Antiochus IV Epiphanes (215-164 B.C.). At one time mercenary soldiers and Hellenized Jews controlled the ancient fortress, enforcing a brutal rule over Jerusalem's residents.

Insight - MERS, Ebola, bird flu: Science's big missed opportunities

By Kate Kelland LONDON (Reuters) - Anyone who goes down with flu in Europe this winter could be asked to enrol in a randomised clinical trial in which they will either be given a drug, which may or may not work, or standard advice to take bedrest and paracetamol. Scientists are largely in the dark about how to stop or treat the slew of never-seen-before global health problems of recent years, from the emergence of the deadly MERS virus in Saudi Arabia, to a new killer strain of bird flu in China and an unprecedented Ebola outbreak in West Africa. "Research in all of the epidemics we have faced over the past decade has been woeful," said Jeremy Farrar, director of the Wellcome Trust global health foundation and an expert on infectious diseases.

The Active Sun: US Unveils Plan to Deal with Space Weather

On Thursday (Oct. 29), the White House released two documents that together lay out the nation's official plan for mitigating the negative impacts of solar flares and other types of "space weather," which have the potential to wreak havoc on power grids and other key infrastructure here on Earth. The new "National Space Weather Strategy" outlines the basic framework the federal government will pursue to better understand, predict and recover from space-weather events, while the "National Space Weather Action Plan" details specific activities intended to help achieve this broad goal. "The efforts undertaken to achieve the objectives of this strategy will establish a national approach to the security and resilience in the face of our improved understanding of the seriousness of the space-weather risk, and the steps we must take to prepare for it," Suzanne Spaulding, undersecretary for the U.S. Department of Homeland Security's National Protection and Programs Directorate, said Thursday during an event hosted by the White House Office of Science and Technology Policy (OSTP) that discussed the new documents.

New 'Star Trek' TV Series Warps Into Action in 2017

The folks at CBS Television Studios announced today (Nov. 2) that a new "Star Trek" series will launch in January 2017, with the premiere episode airing on CBS's television network. The rest of the episodes to the as-yet unnamed series will air first on CBS All Access, the studio's digital streaming arm. Alex Kurtzman, a co-writer and producer on the Trek reboot films "Star Trek" (2009) and "Star Trek Into Darkness" (2013), will serve as executive producer of the new TV series alongside Heather Kadin.

Low-hanging fruit - scientists unlock pineapple's genetic secrets

By Will Dunham WASHINGTON (Reuters) - The pineapple, the tropical fruit enjoyed by people worldwide in slices, chunks, juice, upside-down cakes, jam, tarts, ice cream, yogurt, stir-fry dishes, piña coladas, glazed ham and even Hawaiian pizza, is finally giving up its genetic secrets. Scientists on Monday said they have sequenced the genome of the pineapple, learning about the genetic underpinning of the plant's drought tolerance and special form of photosynthesis, the process plants use to convert light into chemical energy. The genome provides a foundation for developing cultivated varieties that are improved for disease and insect resistance, quality, productivity and prolonged shelf life, University of Illinois plant biologist Ray Ming said.

Micro Mollusk Breaks Record for World's Tiniest Snail

An itsy-bitsy mollusk in Borneo is the new record holder for the world's smallest known snail, a new study finds.

Cannibal Tyrannosaurs: Proof May Be in a Gnawed Bone

Sixty-six million years ago, a tyrannosaur may have sunk its sharp and serrated teeth into the bones of another tyrannosaur, new research suggests. The gnawed bone may provide evidence that tyrannosaurs ate their own kind, the researchers said. "We were out in Wyoming digging up dinosaurs in the Lance Formation," paleontologist Matthew McLain of Loma Linda University in California said in a statement.

Space revolution hatching in a New Zealand paddock

By Charlotte Greenfield AUCKLAND, New Zealand (Reuters) - The next revolution in space, making humdrum what was long the special preserve of tax-funded giants like NASA, will be launching next year from a paddock in New Zealand's remote South Island. The rocket launch range is not just New Zealand's first of any kind, but also the world's first private launch range, and the rocket, designed by Rocket Lab, one of a growing number of businesses aiming to slash the cost of getting into space, will be powered by a 3D-printed rocket engine - another first. The 16-meter carbon-cased rocket being assembled in a small hangar near Auckland Airport will weigh just 1,190 kilograms, and with fuel and payload will be only about a third the weight of SpaceX's Falcon 1, the first privately developed launch vehicle to go into orbit back in 2008.

Space Station Crew Celebrates 15-Year Streak of Humans in Orbit

Yesterday (Nov. 2) marked 15 years since humans took up permanent residence in the International Space Station, and the six crewmembers on board took some time to talk about what the station means for the future of human spaceflight, and how it's holding up after more than one and a half decades in space. Construction began on the $100 billion International Space Station in 1998, with the launch of the Russian Zarya module. "We've learned a lot from this space station that is very, very important to our future exploration beyond our local space environment," said NASA astronaut Scott Kelly during the news conference yesterday.

Are Americans Eating Healthier? Take This Study with a Grain of Salt

People in the United States have been eating healthier — in fact, a new study finds that improved diets have prevented 1.1 million premature deaths over a 14-year period. However, the overall quality of the American diet remains poor, the researchers said. In the study, the researchers looked at trends in people's diets, pulling data from another study of about 34,000 U.S. adults who were each surveyed twice between 1999 and 2012.The researchers applied a scoring system to the participants' diets called the Alternate Healthy Eating Index 2010, which takes into account people's intake of fruit, vegetables and whole grains, as well as their consumption of unhealthy foods such as sugar-sweetened beverages and processed meats.

Tomb Tells Tale of Family Executed by China's 1st Female Emperor

A 1,300-year-old tomb, discovered in Xi'an city, China, holds the bones of a man who helped the nation's only female emperor rise to power. The epitaphs in the tomb describe how she then executed him and his entire family. Located within a cave, the tomb contains the remains of Yan Shiwei and his wife, Lady Pei.

How a Family Dog May Lower a Child's Asthma Risk

Children who are raised in households with dogs or farm animals during their first year of life may have a lower risk of asthma a few years later, a new study suggests. Among the school-age kids in the study, those who had been exposed to dogs during their first year of life were 13 percent less likely to have asthma at age 6, compared with the school-age kids who had not been exposed to dogs in their first year of life, the researchers found. Based on the new findings, researchers can confidently "say that Swedish children with dogs in their homes are at lower risk of asthma at age 6, and that this risk reduction is seen also in children to parents with asthma," said study author Tove Fall, an associate professor of Uppsala University in Sweden.

Codswallop! Ancient British 'Sea Monster' Mislabeled for 200 Years

"There were some rich gentry in the area who would buy them from quarrymen, prepare them and put them in these big wooden frames," said study co-researcher Judy Massare, a professor of geology at SUNY College at Brockport in New York. At the time, fossil experts assigned the Street specimens to the same species — Ichthyosaurus communis, a common species found in rock layers dating to the Late Triassic and Early Jurassic periods in Street, as well as elsewhere in the United Kingdom. The project began when Dean Lomax, a paleontologist at the University of Manchester, found an ichthyosaur skeleton in the collections of the Doncaster Museum and Art Gallery in the United Kingdom.

As scientists worry about warming world, US public doesn't

WASHINGTON (AP) — Americans are hot but not too bothered by global warming.

Rare Earthquake Trio Shakes Phoenix: What Happened?

A rare trio of earthquakes shook central Arizona Sunday (Nov. 1), startling residents in Phoenix and the surrounding areas. It was preceded by a magnitude-3.2 foreshock at 8:59 p.m. and was followed by a magnitude-4.0 aftershock at 11:49 p.m. Smaller aftershocks may follow, said Ryan Porter, a seismologist at Northern Arizona University. Earthquakes are "pretty uncommon for Arizona," Porter told Live Science.
