Scientists create a joint in the jaw from human adult stem cells, an advance which could revolutionise reconstructive surgery.

German-built robots are to be sent into Earth's orbit to repair 'dead satellites' or push them into outer spaceRobots that rescue failing satellites and push 'dead' ones into outer space should be ready in four years, it has emerged. Experts described the development by German scientists as a crucial step in preventing a disaster in the Earth's crowded orbit.Last year it was reported that critical levels of debris circling the Earth were threatening astronauts' lives and the future of the multibillion-pound satellite communications industry. But senior figures at the German Aerospace Centre (DLR) told the Observer they have been given the go-ahead to tackle a crisis that will come to a head in the next five to 10 years as more orbiting objects run out of fuel.Their robots will dock with failing satellites to carry out repairs or push them into 'graveyard orbits', freeing vital space in geostationary orbit. This is the narrow band 22,000 miles above the Earth in which orbiting objects a

If you have ever taken a long road trip, the windshield of your car will inevitably be splattered with bugs by the time you arrive at your destination. Could the DNA left behind be used to estimate the diversity of insects in the region? In a new study, scientists answer this question, utilizing a novel analysis pipeline that will accelerate future studies of biodiversity.

[NEWS] A tumor-suppressing protein snatches up an important cancer-promoting enzyme and tags it with molecules that condemn it to destruction, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports this week in the journal Molecular Cell. “KEAP1 is a recently discovered tumor suppressor, but how it works has not been known. IKKß is a known oncoprotein that promotes cancer in at least two different ways, but we did not know how it was regulated. We …

Scientists said that it was too early to say whether the mission to search for supplies of water on the Moon had been a success. [VIDEO]

WASHINGTON -- NASA's great lunar fireworks finale fizzled. After gearing up for the space agency's much-hyped mission to hurl two spacecraft into the moon, the public turned away from the sky Friday anything but dazzled. Photos and video of the impact showed little more than a fuzzy white flash.

Although a wide spectrum of human papillomavirus is seen across the population of India, HPV-16 and HPV-18 are the most common types and a vaccination targeting these types could eliminate 75 percent of the cervical cancers in the region, according to data presented at the American Association for Cancer Research Frontiers in Basic Cancer Research Meeting.

If a little vitamin A is good, more must be better, right? Wrong! New research published online in the FASEB Journal shows that vitamin A plays a crucial role in energy production within cells, explaining why too much or too little has a complex negative effect on our bodies. This is particularly important as combinations of foods, drinks, creams, and nutritional supplements containing added vitamin A make an overdose more possible than ever before.
