The findings, presented on March 17 at the Lunar and Planetary Science Conference, describes how the Cassini spacecraft captured images of sunlight glinting off the Punga Mare, suggesting they are not reflective sunlight but waves.

While the light sources are known to be small, scientists have recently built the thinnest possible LEDS using tungsten diselenide. The nano-sized LEDs are arguably stronger and more energy efficient than their thicker counterparts.

With blade-shaped teeth measuring almost 4 inches long, a length of roughly 32 feet and weighing close to 5 tons – the T. gurneyi was at the top of the food chain in the Iberian Peninsula roughly 150 million years ago.

The helium, which is being released at about 60 tons per year, is due to the advent of volcanic activity in the region over the past 2 million years.

The findings, published in the journal Nature, show that common honeybee diseases such as the deformed wing virus (DWV) and the fungal parasite Nosema ceranae can be contracted by wild bumblebees and threaten their survival.

"This planet might have the same mass as Earth, but it is certainly not Earth-like," David Kipping of the Harvard-Smithsonian Center for Astrophysics (CfA), lead author of the discovery, said. "It proves that there is no clear dividing line between rocky worlds like Earth and fluffier planets like water worlds or gas giants."
minty3 writes: A new study suggests that the FDA-approved drug, valproate, may help animals and humans achieve perfect pitch. The drug, which is a " histone-deacetylase" or HDAC inhibitor, was first given to mice who exhibited perfect pitch qualities after taking the drug. Recently, researchers gave the drug to adult men who were then able to identify pitches they couldn’t before.

The first message was 10101100111000101011110110, or “O Canada,” from the country’s national anthem. It was sent over several feet in an open space where it was decoded by a receiver – similar to a police Breathalyzer,
minty3 writes: Scientists say they found kimberlite deposits, a known source of diamonds, in Antarctica.
"The fact they are reporting Group One kimberlites is an important one as diamonds are more likely to be found in this style of kimberlite eruption," Dr. Teal Riley, a survey geologist with the British Antarctic Survey told the BBC about the study. "However even amongst the Group One kimberlites, only 10 percent or so are economically viable, so it's still a big step to extrapolate this latest finding to any diamond mining activity in Antarctica."

The species, Eurygnathohippus woldegabrieli, is about the size of a small zebra, had three-toed hooves and grazed the grasslands of the Afar Region, one of the lowest points in Africa.
