Scientists find 500 U.S. seabed vents of powerful greenhouse gas

Scientists have found 500 seabed vents bubbling methane into the Pacific Ocean off the United States, roughly doubling the number of known U.S. seeps of the powerful greenhouse gas, a study showed on Wednesday. "It appears that the entire coast off Washington, Oregon and California is a giant methane seep," Robert Ballard, who is famed for finding the wreck of the Titanic and has now discovered the 500 new seeps, said in a statement. Nicole Raineault, Director of Science Operations with Ballard's Ocean Exploration Trust, said it was unknown how long the seeps had been active, what triggered them and how much, if any, of the gas reached the atmosphere.

NASA spacecraft loses computer before close encounter with Jupiter

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - NASA's Juno spacecraft lost its main computer and science instruments shortly before it was due to make an orbital pass near Jupiter on Wednesday, scuttling highly anticipated close-up observations of the largest planet in the solar system. The U.S. space agency said the glitch followed an unrelated problem last week that prompted it to skip firing Juno’s braking engine, to steer the probe into a tighter regular orbit around Jupiter. Juno's computer restarted after Wednesday's shutdown and the spacecraft was "healthy," NASA said in a statement.

European Mars lander touches down on red planet: ESA

DARMSTADT, Germany (Reuters) - A space lander touched down on Mars on Wednesday in what is Europe's first attempt to land a craft there since the Beagle 2's "heroic failure" more than a decade ago. Scientists are now awaiting updates on the status of the disc-shaped 577-kg (1,272 lb) Schiaparelli lander, which is testing technologies for a rover due to follow in 2020, the European Space Agency said.

The Surprising Reason Some Foods May Trigger Migraines

People who suffer from migraines often say that eating certain foods triggers their headaches, but a new study suggests that it might not always be the food per se — rather, the bacteria in the mouth may be playing a role. The study found that people with migraines harbored more bacteria in their mouths that had the ability to modify chemicals called nitrates, compared to people without migraines. Some migraine-triggering foods contain nitrates, including processed meats and green leafy vegetables, as well as certain medications.

Adults Usually Can't Catch Kids in a Lie

A new study found that adults correctly classified children's truths and lies 54 percent of the time, or only slightly better than chance. The findings are based on an analysis of 45 previously published experiments involving nearly 8,000 adults and about 1,800 children in all, the researchers said. "[The result] is significantly above chance when you talk about it in statistical terms, but in practical terms, when you say 54 percent and chance is at 50 percent, it's maybe not as significant as we want it to be," said study lead researcher Jennifer Gongola, a doctoral student of psychology and social behavior at the University of California, Irvine.

New Anti-Inflammatory Drugs May Help Treat Depression

A new group of anti-inflammatory drugs may help treat depression, a new review finds. And the link between these drugs and depression may shed light on the role that inflammation plays in the mental health condition, according to the review of previously published research. The new anti-inflammatory drugs, which are currently used to treat autoimmune diseases such as rheumatoid arthritis and psoriasis, were found to also reduce symptoms of depression, according to the review, which was published today (Oct. 18) in the journal Molecular Psychiatry.

Bendable Battery May Power Future Wearable Devices, Smartphones

A new bendable lithium-ion battery that can flex and twist could power wearable devices and one day be used to develop a flexible smartphone, according to Panasonic, which is developing the new battery. Although it's still in the early stages of development, the battery already has been tested to withstand twists, bends and other deformations while maintaining its ability to hold a charge, according to Panasonic. Lithium-ion batteries can be highly volatile if they malfunction, as was the case with the Samsung Galaxy Note 7, which was plagued by battery problems that caused them to overheat and sometimes explode.

Rare, Neolithic 'Goddess' Figurine Discovered in Turkey

An 8,000-year-old statuette of what could be a fertility goddess has been unearthed at a Neolithic site in Turkey, according to archaeologists. The figurine, discovered at Çatalhöyük in central Turkey, was wrought from recrystallized limestone between 6300 and 6000 B.C. That material is rare for an area where most previously discovered pieces were sculpted from clay, the researchers said. The archaeologists think this figurine, which is conventionally associated with fertility goddesses, is also representative of an elderly woman who had risen to prominence in Çatalhöyük’s famously egalitarian society.

Mysterious Bison Hybrid Revealed from Ancient DNA and Cave Paintings

Clever detective work involving research on both ancient DNA and cave paintings from the last ice age has revealed a previously unknown species of hybrid bison, according to a new study. Researchers initially nicknamed the newfound bison the "Higgs Bison," because, just like the once-elusive subatomic particle known as the Higgs Boson, the bison's very existence had never been confirmed, and it took about 15 years to piece together data that proved its existence. But now, thanks to ancient DNA from the creatures' bones, researchers know that the mysterious bison was a hybrid animal that originated more than 120,000 years ago, when the extinct aurochs (the ancestor of modern cattle) and the ice-age steppe bison got together, the researchers said.

Chambers Hidden in Great Pyramid? Scientists Cast Doubt

A group of scientists has just claimed to have discovered two unknown voids or cavities within the Great Pyramid of Giza, the largest pyramid ever constructed in Egypt. Such cavities can be signs of hidden burials or rooms and as such, media outlets across the world immediately ran headlines touting this "discovery." One outlet even went so far as to proclaim that "secret rooms" had been found in the Great Pyramid. However, Live Science has learned that the results are more ambiguous.
