British astronaut Peake to make second space flight
British astronaut Tim Peake is to return to the International Space Station to carry out more research, the government said on Thursday. The announcement was made at London's Science Museum, where the capsule which carried Peake on his previous 186-day 'Principia' mission to the space station was unveiled for display.
Nuclear 'Doomsday Clock' ticks closest to midnight in 64 years
Atomic scientists reset their symbolic "Doomsday Clock" to its closest time to midnight in 64 years on Thursday, saying the world was closer to catastrophe due to threats such as nuclear weapons, climate change and Donald Trump's election as U.S. president. The timepiece, devised by the Chicago-based Bulletin of the Atomic Scientists and displayed on its website, is widely viewed as an indicator of the world's vulnerability to disaster.
Britain plan to leave Euratom could delay new nuclear build
British plans to leave the European Atomic Energy Community (Euratom) when it exits the European Union could raise costs, delay new nuclear power projects and complicate research and international cooperation agreements, experts said on Friday. On Thursday, Britain published the legislation it will use to seek parliamentary approval for triggering the process for leaving the European Union, saying the Prime Minister has the power to notify the European Council of withdrawal.
Defying Trump, Twitter feeds for U.S. government scientists go rogue
Rogue Twitter feeds voicing employee concerns at more than a dozen U.S. government agencies have been launched in defiance of what they say are President Donald Trump's attempts to muzzle federal climate change research and other science. Representing scientists at the Environmental Protection Agency, NASA and other bureaus, either directly or through friends and supporters, the accounts protest restrictions they view as censorship since Trump took office on Jan. 20.
U.S. scientists create metallic hydrogen, a possible superconductor, ending quest
U.S. scientists have succeeded in squeezing hydrogen so intensely that it has turned into a metal, creating an entirely new material that might be used as a highly efficient electricity conductor at room temperatures. The discovery, published in the journal Science on Thursday, provides the first confirmation of a theory proposed in 1935 by physicists Hillard Bell Huntington and Eugene Wigner that hydrogen, normally a gas, could occur in a metallic state if exposed to extreme pressure.
NASA unveils spaceship hatch 50 years after fatal Apollo 1 fire
NASA on Friday marked the 50th anniversary of its moon program's fatal Apollo launchpad fire with the first public display of the scorched hatch that trapped three astronauts inside their spaceship during a routine pre-launch test. NASA astronauts Virgil "Gus" Grissom, Edward White and Roger Chaffee died when thick smoke filled the crew module of the Apollo 1 capsule on Jan. 27, 1967, in what was the first deadly accident in the space agency's early days.
