Meet asteroid 1999 RQ36, a chunk of rock and dust about 1,900 feet in diameter that could tell us how the solar system was born, and perhaps, shed light on how life began. It also might hit us someday.

Women in the UK who have ever used the oral contraceptive pill are less likely to die from any cause, including all cancers and heart disease, compared with never users, according to new research.
Engineers developed a computer-controlled, motorized hand and arm support that will let doctors, artists and others precisely control scalpels, brushes and tools over a wider area than otherwise possible, and with less fatigue.
R-rated movies portray violence and other behaviors deemed inappropriate for children under 17 year of age. A new study finds one more reason why parents should not let their kids watch those movies: adolescents who watch R-rated movies are more likely to try alcohol at a young age.

By precisely tracking NASA’s Cassini spacecraft on its low swoops over Saturn’s moon Titan, scientists have determined the distribution of materials in the moon’s interior. The subtle gravitational tugs they measured suggest the interior has been too cold and sluggish to split completely into separate layers of ice and rock.

Seaweed extract may eventually emerge as a lymphoma treatment, according to laboratory research. Seaweeds containing fucoidan, a sulfated polysaccharide similar to heparin in chemical structure, have been reported to have anti-tumor activity in mice and some cell lines.

Researchers have created a molecular image of a system that moves electrons between proteins in cells. The achievement is a breakthrough for biology and could provide insights to minimize energy loss in other systems, from nanoscale devices to moving electricity around the country.
Current drugs used to treat heart failure and irregular heartbeat have limited effectiveness and have side effects. New basic science findings suggest a way that treatments could potentially be refined so that they work better and target only key heart-related mechanisms.
