A new geologic study suggests waves of magma ripple and move under the Earth's surface over millions of years, whose fluid motion may account for prehistoric changes in sea level and movement of polar ice sheets due to convection currents in the mantle.

Researchers have taken diseased lungs from a rat and, with a process of chemical washing to reveal the organ's underlying scaffolding and then incubation in a biological slurry of lung cells, have successfully regrown healthy, functional lungs that were subsequently implanted back into the original rat.

By studying the spectral signatures of carbon monoxide between the day and night side of the gas giant exoplanet HD209458b, astronomers have for the first time detected a global superstorm on the planet with winds of up to 10,000 kph.

The discovery of new 3.6-million-year-old male Australopithecus afarensis fossil remains in Ethiopia supports the idea that upright walking in hominids, corresponding to the elongation of our legs, evolved even earlier than previously believed.

A new technology combining evaporative cooling membranes with liquid dessicant salt solutions (DEVap) produces commercial-grade air conditioning that uses 50% to 90% less energy than even the most advanced units available on the market today.

For the first time, the extreme gravitational effects of a neutron star consuming a nearby white dwarf have been detected through the x-ray signature of elemental oxygen instead of the more common yet ambiguous iron.

Astronomers have observed an object in the Perseus star-forming region that is in the earliest stages of star formation, having just begun pulling in matter from a surrounding cloud of gas and dust, and is believed to be the earliest protostar yet discovered.

Paleontologists have discovered a variety of dinosaur bones in Alberta, Canada, from the Late Cretaceous that have evidence of mammalian tooth marks, the earliest such gnawing evidence from the primitive mammals of that age.

A hand study reveals the brain's representation and perception of various body parts is highly distorted from the actual proportions, most likely due to the differences in sensory information received from those parts.

New data gathered by the DZero experiment at Fermilab suggests that the as-yet undiscovered Higgs boson, believed to be the quantum mechanism behind mass, may not be a single particle but as many as five differently charged particles.

Tests of a man-made plastic antibody, a custom-designed nanoparticle formed to latch onto a specific antigen and thus trigger the natural immunological response, have yielded significantly greater survival rates in laboratory animals injected with a toxin.

Two strands of hair from an unidentified mammal species have been discovered encased in a piece of 100-million-year-old amber, revealing that they are remarkably similar to the hairs of mammals today and have changed little over time.

Using sonar transmitters and satellite tracking, scientists have discovered that the saltwater crocodiles (Crocodylus porosus) of Asia and Australia ride currents like a surfer to cross large areas of open sea to reach distant and remote locations in the South Pacific.

Archaeologists have unearthed 80 skeletons in York in what they believe is a Roman gladiator graveyard dating from the first century AD, with the remains mostly robust, healthy young men who suffered violent injuries and decapitation yet were buried with respect.
