Sense of invalidation uniquely risky for troubled teens

NANOTECHNOLOGY A study of 99 teens hospitalized out of concern about suicide risk found that a high perception of family invalidation - or lack of acceptance - predicted future suicide events among boys, and peer invalidation predicted future self harm, such as cutting, among the teens in general.

Making oxygen before life

About one-fifth of the Earth's atmosphere is oxygen, pumped out by green plants as a result of photosynthesis and used by most living things on the planet to keep our metabolisms running. But before the first photosynthesizing organisms appeared about 2.4 billion years ago, the atmosphere likely contained mostly carbon dioxide, as is the case today on Mars and Venus.

Curiosity helps learning and memory

Curiosity helps us learn about a topic, and being in a curious state also helps the brain memorize unrelated information, according to researchers at the UC Davis Center for Neuroscience. Work published Oct. 2 in the journal Neuron provides insight into how piquing our curiosity changes our brains, and could help scientists find ways to enhance overall learning and memory in both healthy individuals and those with neurological conditions.

On the Verge of Antimatter—Superconducting Iron Reveals ‘Majorana Particles’

For more than 80 years, physicists have sought out the truth behind one of the most contended theoretical phenomena, known simply as “Majorana particles”. And now with some superconducting iron particles, researchers from Princeton University believe that they have found the particles that at one are both matter and the elusive antimatter.

Who’s the Predator And Who’s the Prey? Wyoming Fights Endangered Gray Wolves

It’s been a war brewing for the last few months, and Wyoming just entered its Hail Mary pass. Only a day after federal court judge Amy Berman Jackson of the Washington D.C. circuit announced that Gray Wolves would once again be inducted to the endangered species list, the state of Wyoming’s Game and Fish Commission appealed to the Secretary of State’s Office in hopes of commencing with its annual wolf-hunting season.

Will Pluto Be A Planet Again? What Happened to the Ninth Planet

For some of us, the shock has still never quite settled in. That distant ball of ice Pluto is still tightly woven in our minds as a true planet and even has its very own place within our planetary moniker: “My Very Excellent Mother Just Sent Us Nine Pizzas”. But back in 2006, the international Astronomical Union (IAU) stripped Pluto of its planetary status declaring the relatively small compact of ice much closer to a satellite in its new second-tier title as “dwarf planet”.

Hell Hasn’t Frozen Over, But Titan May Have

Two years ago, a viscous cloud was seen over Titan’s south pole, and planetary scientists mistakenly made the assumption that the anomaly was ordinary gases floating 300 km above Titan’s surface. However, a new study reveals that the cloud is actually composed of hydrogen cyanide ice, and it’s leading researchers to think that the pole is much colder than they once thought.
