Self-control forecasts better psychosocial outcomes but faster epigenetic aging in low-SES youth Author Affiliations Edited by Shelley E. Taylor, University of California, Los Angeles, CA, and approved June 16, 2015 (received for review March 12, 2015) Significance Stunning View of the Crab Nebula Just Got Five Times Better - Universe Today Images of the Crab Nebula are always a treat because it has such intriguing and varied structure. Also, just knowing that this stellar explosion was witnessed and recorded by people on Earth more than 900 years ago (with the supernova visible to the naked eye for about two years) gives this nebula added fascination. A new image just might be the biggest Crab Nebula treat ever, as five different observatories combined forces to create an incredibly detailed view, with stunning details of the nebula’s interior region. Data from telescopes spanning nearly the entire breadth of the electromagnetic spectrum, from radio waves seen by the Karl G. Jansky Very Large Array (VLA) to the powerful X-ray glow as seen by the orbiting Chandra X-ray Observatory.

Tardigrade Tardigrades (also known as waterbears or moss piglets)[2][3][4] are water-dwelling, segmented micro-animals, with eight legs.[2] They were first described by the German pastor Johann August Ephraim Goeze in 1773. The name Tardigrada (meaning "slow stepper") was given three years later by the Italian biologist Lazzaro Spallanzani.[5] Since 1778, over 1,150 tardigrade species have been identified. Tardigrades are classified as extremophiles, organisms that can thrive in a physically or geochemically extreme condition that would be detrimental to most life on Earth.[6][7][3] For example, tardigrades can withstand temperatures from just above absolute zero to well above the boiling point of water, pressures about six times greater than those found in the deepest ocean trenches, ionizing radiation at doses hundreds of times higher than the lethal dose for a human, and the vacuum of outer space.

Breathtaking Black and White Landscape Photography This is a collection of Black and White photos of nature landscapes. Many people think that nature cannot look as breathtaking as it does in colored pictures. I made this post to prove them wrong. Nature can look even better if the photographer knows how to shoot it.

Watch Comet Johnson Sprint Through Boötes Another binocular comet? You better believe it. Comet Johnson takes center stage at nightfall this month and next. Comet Johnson (C/2015 V2) glowed pale green and displayed a short tail on April 2nd. Chris Schur Nothing against Giacobini, Kresak, Mrkos, and Pajdusakova, but this is one comet name I can pronounce with confidence. Astrophysics: Fire in the hole! Andy Potts In March 2012, Joseph Polchinski began to contemplate suicide — at least in mathematical form. A string theorist at the Kavli Institute for Theoretical Physics in Santa Barbara, California, Polchinski was pondering what would happen to an astronaut who dived into a black hole. Obviously, he would die. But how? According to the then-accepted account, he wouldn’t feel anything special at first, even when his fall took him through the black hole’s event horizon: the invisible boundary beyond which nothing can escape.

20 Cool Pictures of Earth from Space 20 cool pictures of Earth from Space thanks to National Geographic and a collection of amazing photographers. Bombetoka BayPhotograph courtesy Terra/ASTER/NASA and NASA Earth Observatory Sapphire waters tinged with pink sediment seem to get tangled amid emerald vegetation in a satellite picture of Bombetoka Bay, on the northwestern coast of Madagascar. To celebrate Earth Day—which today received the ultimate Internet accolade, a Google Doodle—National Geographic photo editors selected 20 of the most stunning pictures of Earth, as seen from space, including this jewel-toned shot of the island country off the African coast. Captured in 2000 by a NASA satellite, the scene shows where the salty waters of the Mozambique Channel mingle with freshwater outflow from the island's Betsiboka River.

Photo of the Day We all know that San Francisco is going through aches and (growing?)/ shrinking artist pains these days as San Francisco property values sky rocket due to the tech infestation going on around the entire Bay Area. Maybe you work in tech and love it, but since this is an art website, we're interested to how this is affecting artists trying to make ends meet. Some galleries have been forced to close due to 300% rent hikes. Many artists have fled to Oakland, LA and NYC in search of affordable housing and a more vibrant art scene...

Women and Girls Raped in Conflict Need Abortion Care—but the US Is Standing in Their Way In 1973, Jesse Helms, a newly elected United States senator and an ideologue contemptuous of the United Nations, dismissive of international treaties and completely devoid of compassion for the world’s poor, put his name on an amendment to the landmark 1961 United States foreign assistance act banning any use of US funds to support abortion in family planning globally. Over more than four decades, the Helms amendment has been reinterpreted, reinforced, and expanded in American aid policy to the point of rising to a violation of internationally recognized rights of women. An international campaign is now urgently demanding that the United States put an end to this policy, saying that the Helms amendment defies the Geneva Conventions on the rules of war, which the US has pledged to uphold since the 1950s. “The US abortion ban is a major reason that female war rape victims around the world are being denied abortions in humanitarian medical facilities,” the letter said.
