Rosetta sent on collision course to surface of comet

European scientists have sent the Rosetta spacecraft on its final, one-way journey to the surface of a comet, after a historic 12-year mission to discover the secrets of the dusty, icy bodies. The Rosetta spacecraft has been chasing comet 67P/Churyumov–Gerasimenko across more than 6 billion kilometers (3.7 billion miles) of space, collecting a treasure trove of information on comets that will keep scientists busy for the next decade. On Thursday evening, the European Space Agency confirmed the spacecraft had started its "collision maneuver", putting it on course to crash into the comet within 20 minutes of 1040 GMT on Friday.

Scientists: World likely won't avoid dangerous warming mark

WASHINGTON (AP) — A team of top scientists is telling world leaders to stop congratulating themselves on the Paris agreement to fight climate change because if more isn't done, global temperatures will likely hit dangerous warming levels in about 35 years.

Global warming to breach 2C limit by 2050 unless tougher action - study

By Alister Doyle OSLO (Reuters) - Global warming is on track to breach a 2 degrees Celsius threshold by 2050 unless governments at least double their efforts to limit greenhouse gas emissions, scientists said on Thursday. Plans by almost 200 governments to cut greenhouse gases are far too weak to match targets set in a Paris Agreement on climate change last December for a drastic shift from fossil fuels towards greener energies, they said. "We've really got a problem," Robert Watson, a British-American scientist who was among the seven authors of the study and is a former head of the U.N.'s Intergovernmental Panel on Climate Change (IPCC), told Reuters.

Scientists fix fractures with 3D-printed synthetic bone

By Kate Kelland LONDON (Reuters) - Scientists in the United States have successfully treated broken spines and skulls in animals using 3D-printed synthetic bone, opening the possibility of future personalized bone implants for humans to fix dental, spinal other bone injuries. Unlike real bone grafts, the synthetic material - called hyper-elastic bone - is able to regenerate bone without the need for added growth factors, is flexible and strong, and can be easily and rapidly deployed in the operating room. Giving details in a teleconference, the scientists said the results of their animal trials - published on Wednesday in the Science Translational Medicine journal - were "quite astounding".
