'Mud Dragon' fossil shows dinosaurs thrived on eve of destruction

By Will Dunham WASHINGTON (Reuters) - In a humid, tropical jungle in southern China eons ago, a remarkably bird-like dinosaur with wing-like arms, a toothless beak and a dome-shaped crest atop its head became trapped in mud, struggled in vain to escape and died. Workmen blasting bedrock while building a school near the city of Ganzhou unearthed a beautifully preserved fossil of the roughly 6.5-foot-long (2-meter-long) dinosaur, nicknamed the "Mud Dragon," still in that contorted position, scientists said on Thursday. Paleontologist Steve Brusatte of Scotland's University of Edinburgh, who worked on the study published in the journal Scientific Reports, said the fossil adds to the understanding of dinosaur evolution on the eve of destruction.

Mars show home goes on display in London

A show home with features to help its residents survive life on Mars went on display in London on Thursday, offering visitors a glimpse of what setting up house on the red planet could look like if it ever happens. Set in a mocked-up Martian landscape at the Royal Observatory Greenwich, the pod-like construction has room for a bed and a computer desk and space to grow plants and exercise. It was designed in consultation with astronomers at the observatory and Stephen Petranek, author of "How We'll Live On Mars", who was also a consultant on the upcoming National Geographic drama "MARS".

Climate scientists say Trump win means U.S. emissions may not fall as pledged

By Alister Doyle MARRAKESH, Morocco (Reuters) - Donald Trump's election as U.S. president muddies the outlook for efforts to cut greenhouse gases and could mean U.S. emissions stay flat until 2030, compared with deep cuts planned by President Barack Obama, scientists said on Thursday. Republican Trump, who has called climate change a hoax and is expected to favor the coal and oil industries, opposes last year's Paris Agreement by almost 200 nations to combat global warming. ...

Scientists try bacteria to halt invading cheatgrass in West

BOISE, Idaho (AP) — It sounds like science fiction: An unstoppable invader is taking over the West and the best hope to stop its relentless advance is a small team of anonymous scientists.

Republican Trump, who has called climate change a hoax and is expected to favour the coal and oil industries, opposes last year's Paris Agreement by almost 200 nations to combat global warming. In the past year "national climate policies have made little progress, and the road ahead looks even less clear after the results of the U.S. presidential elections," three European scientific groups said in a report of global trends.

Low Vitamin D Linked with Higher Asthma Risk

People who don't get enough vitamin D may be at increased risk for asthma, a new study suggests. The participants were asked whether they had been diagnosed with asthma or experienced wheezing (a symptom of asthma) in the past year. The participants also had a test to determine the level of vitamin D in their blood.

Why Do Sleepy People Drink More Soda?

People who don't get enough sleep drink more soda and energy drinks than those who get the recommended amount of sleep per night, a new study finds. In the study, researchers analyzed information from nearly 19,000 U.S. adults who participated in a national health survey from 2005 to 2012, which included questions about diet and sleep habits. People who said they generally slept 5 hours or less per night drank an average of 21 percent more sugar-sweetened beverages, including soda and energy drinks, than those who generally slept 7 to 8 hours per night, the study found.

Why Humans Don't Have More Neanderthal Genes

Neanderthals and modern humans interbred long ago, but evolution has purged many of our caveman relative's genes from modern human genomes, a new study finds. Neanderthals were the closest extinct relatives of modern humans. Previous research suggested that modern humans migrating out of Africa encountered and interbred with Neanderthals tens of thousands of years ago.

Bird Beaks Are Cooler Than You Think — Literally

Whether stubby, slender, spoon-shaped, flattened or sharply pointed, bird beaks can be highly specialized, and now, researchers have found that some even have built-in AC. For the first time, scientists were able to image tiny structures inside nasal cavities in song sparrow beaks. Previous studies have examined the role that beaks' sizes and shapes play in regulating birds' body temperatures, and how certain bill types are linked to particular climates.

Newfound Ancient 'Sea Monster' Is Largest Yet from Antarctica

About 66 million years ago, an ancient sea monster the height of a five-story office building once gnashed its sharp teeth as it swam around the dark waters of Antarctica, a new study finds. The newfound beast, known as a mosasaur — a Cretaceous-age aquatic reptile that sped through the ancient seas using its paddle-like limbs and long tail — is only the second fossilized mosasaur skull ever found in Antarctica. Scientists with the Chilean Paleontological Expedition discovered the mosasaur skull on Seymour Island in January 2011.

3 More States Legalize Recreational Use of Marijuana: How the Map Looks Now

Voters in California, Massachusetts and Nevada decided yesterday (Nov. 8) to legalize the recreational use of marijuana in their states. In addition, four states voted yesterday to legalize using marijuana for medical reasons: Arkansas, Florida, Montana and North Dakota, Time magazine reported. That means that medical marijuana is now legal in 28 states, and an additional 16 states have laws that allow for limited medical use of the drug, according to Time.

Breast Cancer: The First Sign Isn't Always a Lump

Around 1 in 6 women eventually diagnosed with breast cancer initially go to their doctors with a symptom other than a lump, according to a new study conducted in England. Women who have a symptom of breast cancer other than lumps are also more likely to wait to see a doctor, compared with women who do have lumps, the researchers found. That might put them at risk of worse outcomes if the cancer isn't caught quickly. "It's crucial that women are aware that a lump is not the only symptom of breast cancer," study leader Monica Koo, a doctoral candidate at University College London, said in a statement.

More Science Says Smartphones Spoil Sleep

The more time you spend on your smartphone, the worse you'll sleep, a new study suggests. People in the study who used their smartphones for more time during the month-long study period got less sleep and were less likely to sleep well than those who spent less time on their phones, according to the study. The findings suggest that "exposure to smartphone screens, particularly around bedtime, may negatively impact sleep," the researchers wrote.

Scientists develop new type of HIV test on a USB stick

By Kate Kelland LONDON (Reuters) - Scientists in Britain have developed a type of HIV test using a USB stick that can give a fast and highly accurate reading of how much virus is in a patient's blood. The device, created by scientists at Imperial College London and the privately-held U.S. firm DNA Electronics, uses a drop of blood to detect HIV, then creates an electrical signal that can be read by a computer, laptop or handheld device. The researchers say the technology, although still in the early stages, could allow patients to regularly monitor their virus levels in a similar way to diabetes patients checking their blood sugar levels.
