Trippy! Psychedelic Zebrafish Reveal How Cells Regenerate

In what looks more like a post-impressionist painting than a scientific achievement, a transgenic zebrafish is revealing how hundreds of its cells regenerate in a bouquet of colors. Scientists genetically programmed every cell on the zebrafish's body surface, including its cornea, scales, fins and barbels, to express a unique combination of green, red and blue fluorescent proteins, according to lead scientist Kenneth D. Poss, a cell biology professor at Duke University. The result: images of a technicolored zebrafish — revealing 70 different hues — that could just as easily hang in an art museum as appear in a scientific journal.

Birds Use Alligators As Bodyguards

Birds may use alligators as bodyguards to protect their nests from hungry raccoons and opossums, but gator payment may come at a steep cost — namely, in the form of the birds' chicks that are dropped into the water, researchers say. Previous research found that wading birds — such as storks, herons, egrets, ibises and spoonbills — often choose to nest above alligators. However, there was little research into what, if anything, alligators gained from such arrangements.

Wireless mice leave billions at risk of computer hack: cyber security firm

By Ben Gruber San Francisco, CA (Reuters) - Marc Newlin and Balint Seeber are checking how far apart they can be while still being able to hack into each other's computers. It turns out its pretty far - 180 meters - the length of a city block in San Francisco.  The pair work for Bastille, a startup cyber security company that has uncovered a flaw they say leaves millions of networks and billions of computers vulnerable to attack.  Wireless mice from companies like HP, Lenovo, Amazon and Dell use unencrypted signals to communicate with computers.  "They haven't encrypted the mouse traffic, that makes it possible for the attacker to send unencrypted traffic to the dongle pretending to be a keyboard and have it result as keystrokes on your computer.

Mindfulness Meditation May Reduce Low Back Pain

People with chronic low back pain may benefit from meditating, a new study finds. In the study, a group of people with chronic low back pain participated in an eight-week program called mindfulness-based stress reduction, which involved using meditation to increase their awareness of the present moment, and their acceptance of difficult thoughts and feelings, including their pain. About six months after the start of the study, the people who participated in the meditation program were more likely to experience at least a 30 percent improvement in their ability to carry out daily activities, compared with the people who received only standard treatments for low back pain, such as medication.

A vegetarian world would be healthier, cooler and richer: scientists

By Megan Rowling BARCELONA (Thomson Reuters Foundation) - By eating less meat and more fruit and vegetables, the world could avoid several million deaths by 2050, cut planet-warming emissions substantially, and save billions of dollars in healthcare costs and climate damage, researchers said. A new study, published in the Proceedings of the National Academy of Sciences of the United States of America, is the first to estimate both the health and climate change impacts of a global move towards a more plant-based diet, they said. Unbalanced diets are responsible for the greatest health burden around the world, and our food system produces more than a quarter of greenhouse gas emissions, said lead author Marco Springmann of the Oxford Martin Programme on the Future of Food.

Why You Probably Can't Trust Fitness Tracker Calorie Estimates

If you think your fitness tracker isn't telling you the truth about how many calories you've burned, you're probably right — a new study finds that the devices can vary widely in their calorie estimates and tend to underestimate the number of calories burned. The findings "suggest that most wearable devices do not produce a valid measure of total energy expenditure," the researchers wrote in their article. In the study, conducted in Japan, researchers had each of the 19 healthy people wear a whopping 12 fitness trackers (all at the same time) at various places on their waist, chest and wrist.

DNA data storage could last thousands of years

By Matthew Stock Researchers in Switzerland have developed a method for writing vast amounts of information in DNA and storing it inside a synthetic fossil, potentially for thousands of years. In past centuries, books and scrolls preserved the knowledge of our ancestors, even though they were prone to damage and disintegration. In the digital era, most of humanity's collective knowledge is stored on servers and hard drives. But these have a limited lifespan and need constant maintenance. ...

Pharaoh Ramesses III Killed by Multiple Assailants, Radiologist Says

The New Kingdom Pharaoh Ramesses III was assassinated by multiple assailants — and given postmortem cosmetic surgery to improve his mummy's appearance. Those are some of the new tidbits on ancient Egyptian royalty detailed in a new book by Egyptologist Zahi Hawass and Cairo University radiologist Sahar Saleem, "Scanning the Pharaohs: CT Imaging of the New Kingdom Royal Mummies" (American University in Cairo Press, 2016). Hawass and Saleem studied royal mummies from the 18th to 20th dynasties of Egypt, spanning from about 1543 B.C. to 1064 B.C. Rulers during this period included famous names like Hatshepsut, Thutmose III, Tutankhamun, Seti I and the murdered Ramesses III. Previously, Hawass and colleagues had reported that Ramesses III's throat was slit, likely killing him instantly.

'Boaty McBoatface' Tops Poll to Name Polar Research Vessel

"Name our ship!" This was the call from the Natural Environment Research Council (NERC) in an online poll soliciting names for a U.K. polar research vessel. The whimsical suggestion captured the public imagination and rocketed the humorous moniker into first place, trouncing even recommendations honoring beloved British icons like Sir Richard Attenborough and recently deceased musician David Bowie. The British Antarctic Survey (BAS) currently boasts two polar research vessels — a stately pair of ships named for famed arctic explorers: the Royal Research Ship (RRS) James Clark Ross, used primarily for conducting oceanographic research, and the RRS Ernest Shackleton, which transports cargo, passengers and fuel to polar research destinations.

New Patch Analyzes Sweat to Detect Blood Sugar Levels

A stick-on patch that tracks, and even regulates, blood sugar levels could be used by people with diabetes one day, according to a new study. Unlike finger pricking — the traditional method of monitoring levels of the blood sugar glucose — the new patch detects the levels of glucose in a person's sweat. Research has shown that glucose levels in sweat accurately reflect glucose levels in the blood, the researchers said.

Beetle's chemical signal tells mate, 'Honey, I'm not in the mood'

By Will Dunham WASHINGTON (Reuters) - When a female "burying beetle" is focused on caring for babies and not making new ones, she releases a chemical signal to her libidinous mate that says in no uncertain terms, "Honey, I'm not in the mood." Scientists described on Tuesday how these females employ an anti-aphrodisiac chemical known as a pheromone during a three-day period critical for raising offspring to tell the male she is temporary infertile and prevent him from trying to copulate. It provides insight into how animals change their behavior to provide care for their young, in this instance favoring parenting over sexual activity to produce new offspring. "Our study helps to understand animal family life and how it is coordinated between family members," said biologist Sandra Steiger of Germany's University of Ulm, who led the study published in the journal Nature Communications.

Snakes on Planes? Serpents Accelerate Faster Than Fighter Pilots

Snakes can strike faster than the blink of an eye and can reach cheek-jiggling accelerations that would cause a fighter pilot to black out, new high-speed video reveals. Instead, ordinary, nonvenomous constrictors such as rat snakes can often strike as fast as their deadly counterparts. "I was quite shocked to see the short strike durations and high strike accelerations coming from an unassuming, easily found rat snake," said study lead author David Penning, a functional morphology doctoral candidate at the University of Louisiana at Lafayette.

Carbon emissions highest in 66 million years, since dinosaur age

By Alister Doyle OSLO (Reuters) - The rate of carbon emissions is higher than at any time in fossil records stretching back 66 million years to the age of the dinosaurs, according to a study on Monday that sounds an alarm about risks to nature from man-made global warming. Scientists wrote that the pace of emissions even eclipses the onset of the biggest-known natural surge in fossil records, 56 million years ago, that was perhaps driven by a release of frozen stores of greenhouse gases beneath the seabed.
