How the Earth stops high-energy neutrinos in their tracks

For the first time, a science experiment has measured Earth's ability to absorb neutrinos -- the smaller-than-an-atom particles that zoom throughout space and through us by the trillions every second at nearly the speed of light. The experiment was achieved with the IceCube detector, an array of 5,160 basketball-sized sensors frozen deep within a cubic kilometer of very clear ice near the South Pole.

Surprising roles for muscle in tissue regeneration, study finds

Researchers have illuminated an important role for different subtypes of muscle cells in orchestrating the process of tissue regeneration. Notably, in the absence of these muscles, regeneration fails to proceed.

Lightning, with a chance of antimatter

Researchers find that lightning strikes causes photonuclear reactions in the atmosphere, creating antimatter.

New mechanisms found of cell death in neurodegenerative disorders

New mechanisms of cell death have now been discovered, which may be involved in debilitating neurodegenerative disorders, such as Alzheimer's disease and Parkinson's disease, report scientists.

New method to measure neutron star size uses modeling based on thermonuclear explosions

Neutron stars are made out of cold ultra-dense matter. How this matter behaves is one of the biggest mysteries in modern nuclear physics. Researchers developed a new method for measuring the radius of neutron stars which helps them to understand what happens to the matter inside the star under extreme pressure.

First interstellar visitor described as an ‘oddball’

The first object ever known to enter our solar system from beyond is not your average asteroid or comet.

Proposed cuts to US Malaria Initiative could mean millions more malaria cases

Cutting the budget of the President's Malaria Initiative (PMI) by 44 percent, as the US Congress has proposed, would lead to an estimated 67 million additional cases of malaria over the next four years, according to a mathematical model.

Second HIV test helps prevent incorrect HIV diagnosis in infants

Confirmatory HIV testing can substantially reduce the number of infants in South Africa who may be falsely diagnosed as HIV-infected and started on unneeded treatment, according to a new study. Next Page »
