NASA Regains Contact With 'Dead' Solar Mission
NASA has finally re-established contact with a sun-watching probe that was thought to be lost in space after it abruptly went silent in 2014. A signal from the long-lost spacecraft, called STEREO-B, was detected Sunday evening (Aug. 21) by NASA's Deep Space Network, a collection of space tracking stations that follows the agency's space missions across the solar system and beyond. NASA scientists had kept vigil for STEREO-B, making monthly searches for the probe until it phoned home Sunday at..>> view originalNASA's hopes for Mars and the future are at stake in the 2016 election
Election years are a tense time for NASA. A new president can completely alter NASA’s long-term goals by resetting the space agency’s agenda. Whoever is elected will be faced with a choice: change the focus or scope of NASA’s goals, or keep things going on the same track. And given the uncertainty that has plagued NASA for a while, it’s very possible that major changes are on the horizon. NASA’s human spaceflight program stands at a significant crossroads NASA’s human spaceflight program stan..>> view originalWashington to Kill 11 of State's 90 Endangered Gray Wolves for Preying on Cows
Washington state wildlife officials have been cleared to exterminate a pack of 11 endangered wolves after the animals were determined to have been preying on cows. There are only 19 confirmed gray wolf packs in all of Washington state, comprising just 90 wolves, according to a June census by the state Department of Fish and Wildlife. Killing the so-called Profanity Peak pack would remove more than 12 percent of the confirmed state population. A gray wolf.

Through a glistening snow of organic debris, the behemoth appears before the remotely operated vehicle: a sunken aircraft carrier human eyes haven’t seen in 65 years. “Oh my God,” Jim Delgado mutters over the comms, “hello Mighty I.” He’s finally glimpsed his unicorn, the USS Independence. On Monday evening, scientists aboard the research vessel Nautilus piloted two ROVs 2,600 feet deep off the coast of San Francisco to find this icon of World War II, all the while livestreaming their discovery..>> view originalWhy are microbeads controversial?
Image copyright Thinkstock MPs have recommended banning the tiny particles of plastic called "microbeads" which are used in a number of cosmetics and cleaning products. But why have they taken the move?Microbeads is the term given to the little bits of plastic that are sometimes added to products for their abrasive properties.For example, in shower gels these tiny plastic pieces - smaller than 5mm - are designed to remove dry cells from the surface of the skin.They are also found in shower ..>> view originalDream team of historians proposed to advise US president
FILE--In this Feb. 5, 2013 file photo, Graham Allison, Professor of Government at Harvard’s John F. Kennedy School, listens during an event in Boston. Imagine a dream team of the nation’s top historians, recruited by the White House to advise the president on major decisions. That’s the idea being pitched by two Harvard University scholars who allege that many U.S. leaders know alarmingly little about history, both in their own country and in others. Campaigns for Hillary Clinton and Donald ..>> view originalChina unveils 2020 Mars mission probe and rover

DNA circuits aren’t exactly new — they have previously been designed to solve problems like calculating square roots and playing games like tic-tac-toe — but they have almost always been digital, which is to say, information they process is translated into the binary code of zeroes and ones. But researchers from Duke University have made a nanoscale computer that uses synthetic DNA and is analog.Think of it like the difference between a regular calculator and an abacus.Unlike electrical circuits..>> view originalMelting Arctic ice is the "new normal," NASA says
It is by now a familiar headline -- the Arctic sea ice is melting at increasingly rapid rates. This year’s melt season started at an alarming pace, with a record-low maximum ice extent in March, the melt slowed down by June. While this summer won’t be setting a melt record, NASA scientists now say we have to consider this kind of melt “the new normal.”“A decade ago, this year’s sea ice extent would have set a new record low and by a fair amount. Now, we’re kind of used to these low levels of se..>> view originalSeeing through to a mouse's nervous system
