How a Fish That Hatches in Coral Reefs Finds Its Way Home
The larvae of fish that live in coral reefs are tiny, and they are not very good swimmers. They are pushed by currents away from the reefs on which they were hatched for days or weeks until they learn to swim. Then, somehow, around 60 percent of them make their way back to their birthplaces, where they spend the rest of their lives.Scientists know that they can navigate using the position of the sun by day. But they find their way at night, too, and now researchers think they know how: They are..>> view originalWhere to Land on Mars: NASA Makes Progress in Quest for 2020 Rover Site
A small basin (center foreground) lies below the southern rim of Melas Chasma, part of Valles Marineris on the surface of Mars. This is one of eight potential landing sites where NASA may send its Mars 2020 rover. Credit: NASA/JPL-Caltech/Arizona State University, R. Luk While it's always difficult to choose just one best landing site on Mars, NASA officials say they have made progress on picking a location for the Mars 2020 rover.

The prospect of California’s elevated role on climate change is the latest sign of how this state, where Hillary Clinton defeated Mr. Trump by more than four million votes, is preparing to resist the policies of the incoming White House. State and city officials have already vowed to fight any attempt by Washington to crack down on undocumented immigrants; Los Angeles officials last week set aside $10 million to help fund the legal costs of residents facing deportation. The environmental effort..>> view originalSealdah-Ajmer Express derailment - Major railway accidents in India

2016 was a milestone year in the continued warming of the planet. From unstable agriculture to the drought in California to melting ice sheets to extreme weather events and heat waves, climate change has disrupted virtually every corner of the world.It’s impossible to exhaustively list all the ways in which climate change was felt in 2016, but here’s a guide to understanding the year that was for the planet:A carbon dioxide milestone“In the centuries to come, history books will likely look back ..>> view originalChina: We will be on Mars by 2020
(CNN) - China is aiming to own the race for space in the next decade.China's ambitious and fast-growing space program is targeting a landing on the dark side of the moon by 2018, and reaching Mars before the end of the decade.The country's space agency held a press conference on Tuesday to mark the release of a policy paper, and outlined the government's ambitious goals for exploring deep space.Wu Yanhua, deputy chief of the National Space Administration, said Beijing aims to launch its first M..>> view originalOnly 7100 Cheetahs Left In The Wild: Extinction Looming For World's Fastest Mammal
The remaining population of the cheetah in the wild hints that the world's fastest mammal is heading toward extinction. Only 7,100 Cheetahs Left In The Wild A new study that looked into the number of the speedy big cat estimated that there are only 7,100 of these animals left in the wild. The findings prompted calls for the International Union for the Conservation of Nature (IUCN) to re-categorize the species from vulnerable to endangered. More than half of the surviving cheetahs in the world t..>> view originalVera Rubin, 88, Dies; Opened Doors in Astronomy, and for Women
Scientists now know we are not the center of the universe, nor are we even made of the same stuff as most of creation. Cosmologists have now concluded that there is five or 10 times as much dark matter in the universe as there is ordinary atomic matter — the stuff of stars, planets and people.What it is, nobody knows, although theories abound, and attempts to identify it in laboratory and particle-accelerator experiments and in outer space have transfixed modern physics.“We know very little abo..>> view originalStanford scientists assemble world's smallest…
MENLO PARK — Using microscopic bits of diamonds, scientists at SLAC National Accelerator Laboratory have created the world’s smallest electrical wire, measuring only three atoms wide. The tiny necklace holds big promise for the field of nanotechnology, offering a technique for the future construction of molecular-scale mesh material that could be useful for ever-smaller and more efficient electronics or fabrics that generate electricity. “It’s the first time wires this size have been created,” ..>> view original
