Problem of space junk takes center stage as experts testify before a U.S. House committee. Catastrophic collisions are a real risk, lawmakers hear.
Supercomputers grind away for months to create most realistic model ever of the universe's evolution. The computer model is impressive in its accurate recreation of the observable universe.
The scientist who led a British effort to put a spacecraft on Mars has died. The Beagle 2 project to land on Mars was called a "heroic failure."
Humans, with all their electronic devices and gadgets, may be "jamming" the internal compass of migrating birds, researchers say. It's all down to electromagnetism.
NASA says latest solar flare was the best-observed event ever. Four spacecrafts and a ground telescope witnessed.
Tiny "bunker-buster" type missiles could burrow instruments into Mars to look for signs of life, group says. Technology will be tested in California this year.
Observations of star clusters have astronomers scrambling for new theory of how they are formed. Previous theories don't match what they're seeing, they say.
Obesity in young adults suggests greater risk of health problems throughout their lives, study finds. Actual weight, not years of being obese, is most accurate measure of risk, researchers say.
Dinosaurs could take it as well as dish it out, researchers say. Fossils show dinos could recover from even the most grisly injuries.
Close fly-by of asteroid renews urgency of need to find and track asteroids that could threaten the Earth. NASA is holding competitions in hopes of finding solutions.
Scientists help island birds deal with parasites by providing "self-fumigating" nest- building material. Finch nests built with treated cotton found to be free of the parasites.
Theory of continental drift, once a scientific laughingstock, has its history and validation described in the latest "Cosmos" episode. The contributions of brave geologists willing to support it in the face of ridicule is highlighted.
The world's governments must step up and be counted in the effort to halt the impacts of climate change, U.N. chief says. He calls for action ahead of climate summit in New York in September.
Blood from young mice, when introduced into elderly mice, acts like fountain of youth researchers say. The findings could have applications for the treatment of human age-related diseases like Alzheimer's.
