Waves Spotted On Titan

minty3 minty3 writes  |  about 8 months ago

minty3 (2942557) writes "Planetary scientists believe they have observed waves rippling on one of Titan’s seas. 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."

Scientists Build Thinnest Possible LEDs

minty3 minty3 writes  |  about 8 months ago

minty3 (2942557) writes "LEDs are commonly found in TV screens, computer monitors and light bulbs. 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."

Europe's Largest Predatory Dinosaur Discovered In Portugal

minty3 minty3 writes  |  about 8 months ago

minty3 (2942557) writes "The new species, named Torvosaurus gurneyi, describes one of the largest carnivorous dinosaurs from the Jurassic period. 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."

Helium Discovered Under Yellowstone National Park

minty3 minty3 writes  |  about 9 months ago

minty3 (2942557) writes "Vast stores of helium that have accumulated in the Earth’s crust for up to 2 billion years are escaping through volcanic rocks beneath the national park, a new study published in the journal Nature suggests. 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."

Honeybee Disease Found 'Replicating Inside' Wild Bumblebees

minty3 minty3 writes  |  about 9 months ago

minty3 (2942557) writes "Diseases found in managed honeybee colonies have spread to wild bumblebee populations, a new study suggests.

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."

New Earth-Mass Planet Discovered

minty3 minty3 writes  |  about 10 months ago

minty3 (2942557) writes "A team of international astronomers have discovered the first Earth-mass planet that crosses in front of its host star. It is the lightest planet to have its mass and physical size measured.

"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.""

Perfect Pitch Drug May Help Non-Musicians Identify Musical Notes

minty3 minty3 writes  |  about a year ago

minty3 (2942557) 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."

First Text Message Sent Using Vodka

minty3 minty3 writes  |  about a year ago

minty3 (2942557) writes "A team of scientists have successfully found a way to communicate between two points using alcohol molecules evaporated into the air.

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,"

Diamonds Found In Antarctica?

minty3 minty3 writes  |  about a year ago

minty3 (2942557) 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.""

4.4 Million-Year-Old Horse Fossil Found

minty3 minty3 writes  |  about a year ago

minty3 (2942557) writes "Scientists have uncovered a new species of fossil horse drawn from a 4.4 million-year-old fossil-rich deposits in Ethiopia. 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."

New Bird Flu Strain Remains Powerful After Becoming Drug Resistant

minty3 minty3 writes  |  about a year ago

minty3 (2942557) writes "A new strain of the bird flu has been identified by researchers that remains powerful after becoming resistant to antiviral drugs.

The findings, published in Nature Communications, reveals how an avian strain of influenza A has emerged that can develop a resistance to antiviral medications. Labeled as H7N9, the mutation that originated in China, has no vaccine to protect patients from the potentially deadly virus."

New Dinosaur 'Siats Meekerorum' Discovered In Utah

minty3 minty3 writes  |  about a year ago

minty3 (2942557) writes "Named Siats meekerorum, after the man-eating monster from the Ute tribal legend, the fossil belongs to a species of giant meat eaters known as carcharodontosaurs and is the second one discovered in North America.

“This thing is gigantic,” Lindsay Zanno, a paleontologist at North Carolina State University, who discovered the species, said. “There’s simply nothing even close in this ecosystem to the size of this animal that could’ve been interpreted as an apex predator.”"

World's Smallest FM Radio Transmitter Created With Graphene

minty3 minty3 writes  |  1 year,1 day

minty3 (2942557) writes "The team used graphene’s mechanical “stretchability” in order to create a voltage controlled oscillator (VCO) – an electronic component that can generate an FM signal. The VCO was used to send and receive audio signals of 100 megahertz. The team used pure tones and more complex music signals to tune the VCO’s output and found that both kinds of signals could be “faithfully reproduced” by an ordinary radio receiver."

Oldest Body Of Seawater Found In Chesapeake Bay

minty3 minty3 writes  |  1 year,2 days

minty3 (2942557) writes "The seawater, found 0.6 miles underground is most likely 100 to 145 million years old – a remnant of the Early Cretaceous North Atlantic Sea. The findings support the theory that the North Atlantic Ocean’s transition from a closed basin to open ocean caused saline levels to decrease."

Mars Curiosity Rover Finds Granite In Ancient Volcano

minty3 minty3 writes  |  1 year,3 days

minty3 (2942557) writes "Granite, scientists suggest, could have formed on the Red Planet after large amounts of feldspar were discovered in an ancient volcano.

"We think some of the volcanoes on Mars were sporadically active for billions of years," James Wray, the study’s lead author, said. "It seems plausible that in a volcano you could get enough iterations of that reprocessing that you could form something like granite.""
