SpaceX capsule built for humans lands in Atlantic after space station stay

Technology
The unmanned Dragon capsule from Elon Musk's SpaceX has splashed down after a short stay at the International Space Station.It is the first time a commercial space system built for humans has been successfully flight tested by NASA. The capsule - containing a dummy called Ripley - reached hypersonic speeds after detaching from the ISS and splashed down off Florida at 8.45am local time. Its descent was slowed by four parachutes and recovery boats raced to intercept it about 200 miles off the Atlantic coast.Benjamin Reed, SpaceX's director of crew mission management, said: "Everything happened just perfectly, right on time the way that we expected it to." Dragon launched from Kennedy Space Center on a rocket last Saturday, in a major step towards reviving America's human spacefligh...

'This time we'll stay': NASA to send humans to the moon

Technology
By Ajay Nair, news reporter NASA is planning to take the "next giant leap in deep space exploration" as it looks to send astronauts to the moon who are able to stay there.The space agency's administrator, Jim Bridenstine, called for American firms to help develop human lunar landers - "reusable systems for astronauts to land on the moon" - as he said scientists had been given a mandate by President Donald Trump and Congress to return to the moon for the first time since 1972. He said NASA was planning to send astronauts "to the moon and eventually to Mars and beyond" and that it was "an exciting time to be leading America's space programme"."As a lifelong NASA supporter, I am thrilled to be talking once again about landing humans on the moon," he said, wr...
Ancient skull provides earliest evidence of modern humans in Mongolia

Ancient skull provides earliest evidence of modern humans in Mongolia

Science
Jan. 30 (UPI) -- An ancient Mongolian skull thought to belong to the a unique species of Pleistocene hominin, dubbed Mongolanthropus, is actually the earliest evidence of modern humans in the region. Using radiocarbon dating and DNA analysis, paleontologists determined the skull belonged to Homo sapiens. The discovery is described in a new paper published Wednesday in the journal Nature Communications. As a result of compromised dating efforts and the fossil's archaic skull features, some researchers previously hypothesized the hominid remains hailed from the mid to late Pleistocene and belonged to Homo erectus or the Neanderthals. The new analysis posits that the modern human specimen lived sometime between 34,950 and 33,900 years ago. Because the skull is contaminated with a variety of...
How computers may eventually beat humans at their own games

How computers may eventually beat humans at their own games

Technology
This is an Inside Science story. A new computer program taught itself superhuman mastery of three classic games -- chess, go and shogi -- in just a few hours, a new study reports. These findings could help lead to artificial intelligence programs that could learn to play and master any game, and perhaps other human tasks, researchers said. From the first days of computing, games have served as benchmarks of how well machines perform in tasks humans also find challenging. Since the computer Deep Blue beat world chess champion Garry Kasparov in 1997, AIs have defeated humans at even more computationally difficult games. For example, in 2016, AlphaGo from the company DeepMind in London bested a master of the ancient Chinese game of go, achieving one of the Grand Challenges of AI at least a...
Pig hearts transplanted into baboons – could humans be next?

Pig hearts transplanted into baboons – could humans be next?

Technology
Pig hearts have been transplanted into baboons - a development that could pave the way for humans to receive porcine organs in future. Researchers from Germany, Sweden and Switzerland said two Anubis baboons had survived for six months, while another two lived for at least three months.Previously, the longest a baboon had survived after such a procedure was 57 days.Since then, genetic modifications have been made to the hearts and a new transplant technique has been developed. Image: The transplant procedure was refined during three trials.
