Fan-Designed Lego Saturn V Moon Rocket Qualifies for Product Review

A fan-designed scale model of NASA's historic Saturn V rocket has landed on Lego's launch pad and is now waiting an official "go/no-go" call as to whether it will lift off as a commercial set. The 3-foot-tall (1 m) version of the iconic Apollo 11 booster climbed to its qualifying 10,000th vote on Friday (Nov. 20) on the Lego Ideas website. The rocket, designed by Felix Stiessen and Valerie Roche, will now be considered by the Danish toymaker for possible production when it convenes its next review in January.

U.S. Air Force official sees issues with space launch priorities

By Andrea Shalal WASHINGTON (Reuters) - The United States could struggle to promote competition in its space launch program while also maintaining two independent ways to launch satellites and ending U.S. reliance on Russian rocket engines, a top U.S. Air Force official said on Tuesday. ULA, the monopoly provider of such launches since its creation in 2006, said it was unable to submit a bid in compliance with the competition's rules because of how the contest was structured, and because it lacked Russian-built RD-180 engines for its Atlas 5 rocket. The Pentagon last month refused to grant ULA a waiver from a U.S. law that banned use of the Russian engines for military and spy satellite launches after 2019.

Billionaire Battle: Jeff Bezos, Elon Musk Square Off on Reusable-Rocket Test

A reusable-rocket milestone has sparked a mini-squabble between two of the billionaires who are helping transform the private spaceflight industry. On Monday (Nov. 23), Blue Origin — a company established by Amazon.com founder Jeff Bezos —launched a rocket into suborbital space and then brought it back down for a soft landing at a pad in West Texas. The uncrewed test marked a big step toward full rocket reusability, which could open the heavens to human exploration by dramatically lowering the cost of spaceflight, Bezos said.

Meteor Showers on Mercury May Explain Astronomical Puzzle

Mercury can experience meteor showers as Comet Encke periodically peppers the planet's tenuous atmosphere with dust, new research suggests. Compared to Earth's and Mars' atmospheres, Mercury's is much less substantial — made of just clouds of atomic particles formed from surface ejections or the solar wind — but the particles still have an effect on the exosphere, the outer fringe of its atmosphere. The new Mercury finding came after scientists were puzzled by a strange pattern in calcium observed in the thin atmosphere of the crater-filled planet.

Manned Mission to Mars Must Not Ignore Human Struggles, Expert Stresses

A successful crewed Mars campaign must recognize, and take pains to ameliorate, the psychological and cultural challenges that Red Planet pioneers will face, a prominent space architect says. For example, a manned mission to Mars must take into account sojourning astronauts' lengthy isolation from friends and family, said Marc Cohen, of the California-based company Astrotecture. "Ironically, the same can-do spirit that characterized so many of the successes throughout the space age also blinds the current crop of Mars advocates to the profound challenges of habitability that lie ahead," Cohen said Nov. 4 during a presentation to NASA's Future In-Space Operations working group.

Charitable Acts Can Lead to Bad Behavior

After donating to a major fundraiser in the Netherlands, participants in a new study became less interested in behaving in an environmentally friendly manner. People may feel good about themselves after acting charitably, feeling like they have a license to behave a little worse later, said study leader Marijn Meijers, a psychologist at the University of Amsterdam. "After you do something moral or laudable, you're more likely to behave a little less laudable," Meijers told Live Science.

Cause of Mysterious Snake Die-Off Found

The culprit behind a disease that causes raised blisters, crusted-over eyes and snouts, discolored skin patches, and ultimately death in several snake species has been identified. A fungus called Ophidiomyces ophiodiicola is responsible for the snake deaths in the American Midwest and East, researchers now say. Researchers had suspected O. ophiodiicola was responsible for snake fungal disease (SFD) because they had found the fungus on snakes that died of SFD in the past.

Slipping into a Food Coma? Blame Your Gut Microbes

When you push away your plate, loosen your belt and announce, "I couldn't manage another bite!" it may be your gut microbes talking, according to a new study. About 20 minutes after a person eats, E. coli bacteria, which are common in the human gut, produce proteins that scientists have connected to a hormone responsible for appetite suppression response in the brain. This is one of the first studies to explore the mechanisms that connect microbial activity to responses in the human body associated with behavior.

Light-Bending Microchip Could Fire Up Quantum Computers

Although this advance will not enable faster-than-light starships, the light-warping technology behind this innovation could lead to new light-based microchips and help enable powerful quantum computers, researchers said. Exceeding this speed limit should lead to impossible results such as time travel, according to Einstein's theory of relativity.

Costco Chicken Salad Linked to E. Coli Outbreak in 7 States

An outbreak of E. coli bacteria tied to chicken salad sold at Costco has sickened 19 people in seven states, according to the Centers for Disease Control and Prevention. The patients are infected with a strain of E. coli called O157:H7, which produces a harmful toxin called Shiga toxin. Five people have been hospitalized, and two of those people have developed a type of kidney failure called hemolytic uremic syndrome, which can be caused by the Shiga toxin.

A Pill for ISIS Supersoldiers? Not So Fast

ISIS fighters are using an illegal drug known as Captagon, according to news reports. Captagon is actually a combination of two drugs, theophylline and amphetamine, said Nicolas Rasmussen, a professor of history and philosophy of science at the University of New South Wales in Australia. The combination itself is inactive in the body, but when the body breaks it down into the two component parts, each part becomes active, Rasmussen told Live Science.

7 Tips to Make Thanksgiving More Enjoyable for People with GERD

For many Americans, Thanksgiving revolves around food, family, football and giving thanks. "The primary reason Thanksgiving can be difficult for GERD sufferers is that people tend to overstuff themselves," said Dr. Jacqueline Wolf, a gastroenterologist at Beth Israel Deaconess Medical Center in Boston. People with GERD can get into trouble by eating too much overall, eating too much within a short time and eating bothersome foods that frequently trigger reflux, Wolf said.

Drug driving suit mimics taking the wheel stoned

By Jim Drury A simulation suit that mimics the effects on wearer's reactions of taking illegal substances has been developed by scientists to show young drivers the dangers of getting behind the wheel while intoxicated by drugs. A kinetic device in the suit's gloves produces a tremor akin to that caused by some illicit drugs. Random flashing lights in the goggles' peripheral area, allied to hallucinogenic-type sounds in the headphones, combine to disorientate drivers.

Full Moon Rises Tonight in Pre-Thanksgiving Lunar Show

The full moon tonight (Nov. 25) moon will be at its best tonight at 5:44 p.m. EST (2244 GMT), but to the average skywatcher, the moon can appear full in the day before and the day after the actual event. November's full moon is traditionally known among Native Americans as the Full Beaver Moon. The name Beaver Moon dates back to the Algonquin tribes and early U.S. colonists, apparently because November was the best month to set traps for the small, industrious mammal to gather warm furs for the winter, according to our skywatching columnist Joe Rao.

Scientists create mosquito strain with malaria-blocking genes

By Will Dunham WASHINGTON (Reuters) - Scientists aiming to take the bite out of malaria have produced a strain of mosquitoes carrying genes that block its transmission, with the idea that they could breed with other members of their species in the wild and produce offspring that cannot spread the disease. The researchers said on Monday they used gene-editing, a genetic engineering technique in which DNA can be inserted, replaced or deleted from a genome, on a species called Anopheles stephensi that spreads malaria in urban India. Malaria is caused by parasites transmitted to people through the bites of infected female mosquitoes.

How Earth's Hidden Magma Ocean Formed

The rotation of the newborn Earth may have helped to control the evolution of a giant magma ocean sitting on top of its core, researchers say. Knowing how Earth's magma oceans evolved over time could shed light on when the plate tectonics— the shifting of the rocky slabs that make up the planet and underlie earthquakes and volcanoes — began, scientists added. Previous calculations suggested that Earth possessed one or more giant oceans of magma, or molten rock.

More Infant Deaths Blamed on Crib Bumpers

The number of infant deaths linked to crib bumpers has increased in recent years, according to a new study. Crib bumpers are padded blankets that can be placed inside a crib, to prevent a baby's limbs from getting stuck between the slats. In the new study, researchers found that, over the seven-year period between 2006 and 2012, there were 23 deaths tied to crib bumpers reported to the U.S. Consumer Product Safety Commission (CPSC).

Some of Earth's Rocky Plates Are Gooey on the Inside

Tectonic plates may be similar to chocolate candies: Stiff on the outside, but as soft as marshmallow fluff on the inside. That is the conclusion of a new study that suggests at least some of the rigid plates that cover the Earth's surface may be stretchier than thought. The plate tectonics findings, which were described today (Nov. 23) in the journal Nature Geoscience, are based on investigations of the region under Peru, where the Nazca Plate is diving beneath the continental South American Plate.

Mars May Become a Ringed Planet Someday

In a few tens of millions of years, the Red Planet may completely crush its innermost moon, Phobos, and form a ring of rocky debris, according to the new work. Phobos is moving closer to Mars every year, meaning the planet's gravitational pull on the satellite is increasing. Some scientists have theorized that Phobos will eventually collide with Mars, but the new research suggests that the small moon may not last that long.

Goodbye, Nola: Only 3 Northern White Rhinos Remain in the World

One of the four northern white rhinoceros left on Earth died yesterday (Nov. 22), leaving only three surviving members of the critically endangered species. In recent weeks, Nola suffered from a bacterial infection, and on Nov. 13, the aging animal underwent surgery to drain a large abscess in her pelvic region, which veterinarians finally identified as the source of her sickness. When intensified treatment efforts were unsuccessful, the animal's caretakers chose to euthanize her yesterday, in what was a "difficult decision," according to a statement released by the San Diego Zoo.

Beetles Speed-Grow Their Built-In Bifocal Eyes

Sunburst diving beetles, also known as "water tigers," are efficient predators that depend on their eyes to help them nab their mosquito prey. Each tube holds a lens, cone and retina, which are features common to the image-forming eyes in most vertebrates (and some invertebrates) known as "camera eyes." In camera eyes, images enter the eye through the lens and are reflected onto the retina. "Functionally, their eyes are more similar to our own eyes than to a fruit fly or other insect," Elke Buschbeck, a professor in the Department of Biological Sciences at the University of Cincinnati, and co-author of the new study, told Live Science.

Round for Round: Women's Drinking Rates Catching Up to Men's

Over the decade-long period between 2002 and 2012, the percentage of U.S. women who reported drinking in the past month increased, and so did the the average number of days that women reported drinking, according to the report from researchers at the National Institute of Alcohol Abuse and Alcoholism (NIAAA). The percentage of women who reported drinking alcohol in the past 30 days increased from 45 percent to 48 percent over the study period. Among men, however, the percentage decreased slightly, from 57 percent to 56 percent, according to the findings published today (Nov. 23) in the journal Alcoholism: Clinical and Experimental Research.

Lonely? You May Be More Likely to Get Sick

Loneliness may be a health risk and can even increase a person's risk of premature death, studies have shown, but the reason for the link hasn't been clear. Now, researchers have found one way that loneliness may affect a person's health: It may trigger cellular changes that might lower a person's ability to fight viral infections. In a study of 141 older adults, researchers looked at the relationship between loneliness and patterns of gene expression in white blood cells, which are involved in protecting the body against viruses and bacteria.

Don't Spill the Beans: Zero-G Cup Lets Astronauts 'Smell the Coffee'

Astronauts aboard the International Space Station are testing beverage cups that let them literally wake up and smell the coffee. But astronauts have been testing out some strangely shaped cups that keep liquid under control well enough to contain tasty juice or scalding coffee in an open-topped container, and hold it steady even while astronauts do flips or toss the cups back and forth. "Astronauts' responses when testing out the cups so far range from 'Hey, you can smell the coffee,' to 'This is eerily like drinking on Earth,'" representatives from the American Physical Society's Division of Fluid Dynamics said in a statement.
