Originally thought to be too close to the sun to retain ice, scientists have detected frozen water ice and several organic molecules on the asteroid 24 Themis in the belt located between the orbits of Mars and Jupiter.

Seven huge mounds of extinct asphalt volcanoes have been discovered on the floor of the Pacific Ocean about 10 miles off the coast of California, the largest as tall as a six-story building and estimated to be about 35,000 years old.

New research shows that mammals, including humans, are capable of naturally producing trace amounts of the narcotic morphine in their bodies, leading to questions of how and why such a complicated and costly chemical process evolved.

New genetic analysis of killer whales (orca) worldwide has lead scientists to propose classifying these animals in the wild into four or more distinct subspecies, each with distinct social and hunting behavior, vocalizations and physical appearance.

An unknown and mysterious object has been discovered in the nearby galaxy M82, turning on very rapidly over a year ago and even growing slightly as it is three to ten times brighter than previously known micro-quasars, which generally peak in brightness over a few days or weeks.

A new large species of leech (Tyrannobdella rex, or "tyrant leech king") has been discovered in the remote parts of the Upper Amazon with a preference for inhabiting the mucous membranes of people and animals, among a few other relatively unique physical features.

Researchers have shown how the human brain can handle two tasks at once by dividing attention between the two lobes of the medial prefrontal cortex (MFC), but this same physiology explains why we cannot effectively handle three or more tasks simultaneously.

A group of 27 exoplanets have been discovered with orbits in the opposite direction of their parent star's rotation and not even orbiting in the same plane as the star's rotational axis, challenging current theories of planet formation.

A lightning researcher has discovered that when particularly intense discharges in thunderstorms interact with cosmic rays high in the atmosphere, the conditions are right for a natural particle accelerator as free electrons stripped from air molecules can develop into narrow yet powerful particle beams.

Scientists have discovered an undersea "superhighway" amid a complex of newly disturbed hydrothermal vents responsible for repopulating an area after a recent eruption with tiny life forms from as much as 300 km away.

Previously only a theory, researchers have proven the existence of so-called mirror neurons in the human brain, the mechanism by which we recognize, sympathize and empathize with others and which makes us unique among animals.

Recent Japanese experiments have demonstrated that lightning bolt-strength applications of electricity to the soil can more than double the yield of certain varieties of mushrooms, essentially proving an old farmer's superstition.

The identification of 20 key genes that control kidney functions such as filtering wastes from the blood is being described as "revolutionary" toward an effective treatment for chronic conditions and disease.

New data from the ESA's Venus Express mission has shown evidence of recent lava flows on the surface of Venus, making it one of the few bodies in the solar system to be geologically active within the past 3 million years.

Deep-sea studies in the Mediterranean have revealed new multicellular organisms (loriciferans) up to a millimeter in length living in 10,000-feet deep basins of completely anoxic (oxygen-free) water loaded with toxic levels of sulfides.

A newly discovered fruit-eating monitor lizard (Varanus bitatawa) that lives in trees in the Philippines island of Luzon and can grow to six feet in length has been recognized as a new species, an extremely rare find for large land-dwelling vertebrates.

Scientists have discovered the fossil remains of a Velociraptor caught feeding on the remains of a herbivore Protoceratops and suggesting a scavenging role for the predator, a rare example of evidence for dinosaur behavior.

Inspired by an office toy, researchers have developed an acoustic lens comprised of parallel rows of stainless-steel spheres that could lead to near photo-quality images of internal organs or even "sound bullets" that could be focused to act as sonic scalpels.

NASA's Fermi Gamma-Ray Telescope has discovered massively large but weak "roaming" magnetic fields throughout the universe that may have served as "seed" fields for galactic formation but whose origins predate the galaxies and remain unclear.

Paleontologists in Australia have discovered the first tyrannosaur fossils in the Southern Hemisphere, a distant and smaller relative to T. rex, where previously the species had only been known from fossils found on northern continents.
