Scientists have halted the advance of heart disease in mice -- and even reversed some of its effects. The study provides hard evidence that tiny pieces of genetic material called microRNA can play a key role in the development of heart disease.

Research carried out at MIT's Alcator C-Mod fusion reactor may have brought the promise of fusion as a future power source a bit closer to reality, though scientists caution that a practical fusion powerplant is still decades away.

Forget what's number one at the box office this week. The most exciting new film features the intricate workings of the body, filmed by scientists using ground-breaking technology.

Based on the outstanding success of the first tandem mission between ERS-2 and Envisat last year, ESA has paired the two satellites together again to help improve our understanding of the planet.

In the hit 1998 movie Armageddon, Bruce Willis and Ben Affleck blew up an asteroid to save the world. While the film was science fiction, the chances of an asteroid hitting the Earth one day are very real ― and blowing up an asteroid in real life, says a Tel Aviv University researcher, will be more complicated than in the movies.

Scientists have identified a molecular cause behind the ravages of old age and in doing so have also shown how a natural process for fighting cancer in younger persons can actually promote cancer in older individuals.

Teens are fascinated by their brains, the way they work, change, and even "freeze" sometimes. The American Association for the Advancement of Science (AAAS) recommends that parents, teachers and caregivers use that fascination to engage middle and high school students this holiday season in a discussion of why they shouldn't drink alcohol.

Who knows what evil lurks in the hearts of men? Dr. Prabir Bhattacharya and his computers might. He and Concordia graduate student Abu Sayeed Sohail are developing a computer image processing system that detects and classifies human facial expressions.

Improvements in behavior and screening have contributed greatly to the 13 percent decline in cancer mortality since 1990, with better cancer treatments playing a supporting role, according to new research from David Cutler of Harvard University.

Dr Catherine Leamey from the School of Medical Sciences at the University of Sydney has been awarded the 2008 Sir Zelman Cowen Universities Fund Prize for Medical Research for her work in identifying the gene that enables binocular vision.

A 3D television system which would display holographic images floating in mid air - reminiscent of a famous scene from Star Wars - could be a reality in households throughout Europe within the next decade according to findings by a team of University of Aberdeen academics.

Synthetic biology promises to enable cheap, lifesaving new drugs to treat the 350-500 million people who suffer from malaria, and to create innovative biofuels that can help solve the world's energy problems. But the science and its applications are raising questions: Are synthetic biologists playing God?

Natural changes in voltage that occur across the membrane of adult human stem cells are a powerful controlling factor in the process by which these stem cells differentiate, according to research published by Tufts University scientists.

A group of atheists filed a lawsuit Tuesday seeking to remove part of a state anti-terrorism law that requires Kentucky's Office of Homeland Security to acknowledge it can't keep the state safe without God's help.

That is one of the findings of a study forthcoming in the Journals of Gerontology: Psychological Science. The researchers analyzed the responses of 516 men and women age 70 and older who participated in the Berlin Aging Study, tracking how their perceptions about age and their satisfaction with aging changed over a six-year period.
