The 3-D structure of the virus, known as Seneca Valley Virus-001, reveals that it is unlike any other known member of the Picornaviridae viral family, and confirms its recent designation as a separate genus "Senecavirus."

Scientists have confirmed the second-ever case of a “virgin birth” in a shark, indicating once again that female sharks can reproduce without mating and raising the possibility that many female sharks have this incredible capacity.

Supercomputer simulations of dusty disks around sunlike stars show that planets nearly as small as Mars can create patterns that future telescopes may be able to detect.

Cracking the secrets of the atmosphere of Titan, Saturn’s mysterious moon, and how planetary atmospheres evolve, have come a step closer after evaluation of data from a successful fly-by of its surface by the Cassini spacecraft.

New research has provided the first detailed look at the internal head skeleton of Tiktaalik roseae, the 375-million-year-old fossil animal that represents an important intermediate step in the evolutionary transition from fish to animals that walked on l

Unique observations of the flickering light from the surroundings of two black holes provide new insights into the colossal energy that flows at their hearts.

Researchers have created a new material that overcomes two of the major obstacles to solar power: it absorbs all the energy contained in sunlight, and generates electrons in a way that makes them easier to capture.

A new research field called transformation optics may usher in a host of radical advances including a cloak of invisibility and ultra-powerful microscopes and computers by harnessing nanotechnology and "metamaterials."

Moderate global warming and acid rain actually could be a good thing for northern hardwood forests, because it makes the trees grow faster and store more carbon.

Astronomers have detected long wavelength radio emission from a colliding, massive galaxy cluster which, surprisingly, is not detected at the shorter wavelengths typically seen in these objects.
