New Speckled Venomous Snake Discovered in Cloud Forest

 

New Speckled Venomous Snake Discovered in Cloud Forest A previously unknown, green-speckled species of venomous snake has been found lurking in the high, misty forests of Costa Rica. The snake, which lives in a remote, forested region of Central America, was long mistaken for a closely related species, the black-speckled palm-pitviper (Bothriechis nigroviridis). When two species look and behave nearly identically but are genetically distinct, it's called cryptic speciation. Read More » Goodbye, Weasels! New Zealand to Wipe Out Its Invasive Predators The clock is ticking for the rats, possums and weasels that have invaded New Zealand over the past few hundred years. Before humans landed in New Zealand less than 800 years ago, precious few mammals lived on the islands — a vibrant archipelago that provided a home for flightless birds, such as the kiwi, takahe­ and kakapo parrot, as well as geckos and lizard-like tuataras. "While once the greatest threat to our native wildlife was poaching and deforestation, it is now introduced predators," Key said in a statement.

The print, which measures 1.2 meters (1.3 yards) across, probably belonged to the abelisaurus, a biped dinosaur that once roamed South America, said Argentine paleontologist Sebastian Apesteguia, who is studying the find. The print was found some 64 kilometers (40 miles) outside the city of Sucre in central Bolivia by a tourist guide earlier this month.

Now, a new study reveals the anatomical limits to a honeybee's moves. "Our research on the ultrastructure of the FIM [folded intersegmental membrane] is of great significance to reveal the bending and flexing motion mechanism of the honeybee abdomen," study researcher Shaoze Yan, of Tsinghua University in China, said in a statement.

The last universal common ancestor, or LUCA, is what scientists call the forerunner of all living things. To learn more about how and where LUCA might have lived, researchers analyzed 6.1 million genes from prokaryotes — microscopic, single-celled organisms that lack distinct cell nuclei.

While there are other options for treating waste water, the system applied at the University of Ghent uses a special membrane, is said to be energy-efficient and to be applicable in areas off the electricity grid. "We're able to recover fertilizer and drinking water from urine using just a simple process and solar energy," said University of Ghent researcher Sebastiaan Derese.

"We've been working with [a fire] investigator who works a lot with modern fires, and he thinks there's a good chance that the fire was set deliberately," said Selina Davenport, an archaeologist at the University of Cambridge. "For that to have spread from something like a spark off a hearth is unlikely," Davenport told Live Science. Read More » Huge Quake for the Himalayas? Ancient Hindu Temples Hold Clues Past earthquakes that damaged ancient temples perched high in the Himalayas could be harbingers of dangerous quakes to come, new research suggests.

The American Chemical Society (ACS) recently released a new video showing a fun, at-home science experiment that lets you "grow" fluorescent flowers that glow under black light. It turns out, flowers aren't picky when it comes to their water.

The World Health Organization currently lists transgender identity as a mental health disorder, and the new study is the first in a series of research aimed at finding out whether this categorization is apt. In the new study, published today (July 26) in the journal The Lancet Psychiatry, the researchers investigated whether the distress and dysfunction associated with transgender identity were the result of social rejection and stigmatization or an inherent part of being transgender.

The four sheep, which were derived from the same batch of cells as Dolly and could be considered her clone "sisters," have just reached their 9th birthday, which is equivalent to age 70 in human years, researchers who have been studying the sheep said. All of the sheep were free from many diseases commonly found in older sheep, such as diabetes and high blood pressure, the study showed.

Police officers in the U.S. are more likely to stop or arrest black, Hispanic and Native American people than they are to stop or arrest non-Hispanic white people, a new study finds. The researchers also found that more blacks, Hispanics and Native Americans were killed and injured by police over the study period than non-Hispanic whites. "Both blacks and white Hispanics are four times as likely to be killed by the police as white non-Hispanics are," said lead study author Ted Miller, a senior research scientist at the Pacific Institute for Research and Evaluation in Maryland.

The early-stage finding, reported in the journal Nature on Wednesday, could one day lead to a whole new class of antibiotic medicines being developed to fight drug-resistant bacterial infections, the researchers said. As well as being a focal point for many viral infections, the nasal cavity is also a rich ecosystem of 50 or so different species of bacteria, lead researcher Andreas Peschel of the University of Tuebingen told reporters in a telephone briefing.

(Reuters) - Scientists have long wondered why Jupiter's upper atmosphere has temperatures similar to those of Earth, even though the biggest planet in the solar system is five times farther away from the sun. The answer may be The Great Red Spot, an enormous storm big enough to swallow three Earths that has been raging on Jupiter for at least three centuries, a study showed on Wednesday. Using an infrared telescope at Hawaii's Mauna Kea Observatory, scientists discovered that the upper atmosphere above the Great Red Spot – the largest storm in the solar system - is hundreds of degrees hotter than anywhere else on the planet.
