An expedition of international scientists to the far reaches of Antarctica’s remote Pine Island Glacier has yielded exact measurements of an undersea process glaciologists have long called the “biggest source of uncertainty in global sea level projections.”
Earlier this year, the National Science Foundation's Very Long Baseline Array telescope turned its gaze to NASA's famed Voyager 1 and captured an image of this iconic spacecraft's faint radio signal. The Green Bank Telescope also detected Voyager's signal, picking it out from the background radio noise in less than one second.
University of Iowa space physicist Don Gurnett says there is solid evidence that NASA’s Voyager 1 spacecraft has become the first manmade object to reach interstellar space, more than 11 billion miles distant and 36 years after it was launched. The finding is reported in a paper published in the Sept. 12 online issue of the journal Science.
A new study led by Adelaide researchers has estimated, for the first time, the rates of evolution during the “Cambrian explosion” when most modern animal groups appeared between 540 and 520 million years ago.

A drug approved just two years ago for treating bacterial infections may hold promise for treating the potentially fatal MRSA pneumonia, according to a Henry Ford Hospital study. Researchers found that patients treated with the antibiotic ceftaroline fosamil, or CPT-F, had a lower mortality rate after 28 days than the mortality rate seen in patients treated with vancomycin, the most common drug therapy for MRSA pneumonia.
An important discovery has been made concerning the possible inventory of molecules available to the early Earth.

Imagine if you were wrongly accused of a crime. Would you be stressed? Iowa State University researchers found the innocent are often less stressed than the guilty. And that could put them at greater risk to admit to a crime they didn’t commit.
As Earth’s temperature climbs, stony corals are in decline. Less discussed, however, is the plight of gorgonian corals — softer, flexible, tree-like species. Divers have noted that gorgonians seem to be proliferating in parts of the Caribbean, and a new study will look to quantify this phenomenon.

A new, highly sensitive method to detect genetic variations that initiate colon cancer could be readily used for noninvasive colon cancer screening, according to a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research.
Scientists at Brookhaven National Laboratory used an indirect method to detect fluctuating "stripes" of charge density in a material closely related to a superconductor. The research identifies a key signature to look for in superconductors as scientists seek ways to better understand and engineer these materials for future energy-saving applications.
Ground-breaking new research from a team of evolutionary biologists at Indiana University shows for the first time how asexual lineages of a species are doomed not necessarily from a long, slow accumulation of new mutations, but rather from fast-paced gene conversion processes that simply unmask pre-existing deleterious recessive mutations.
University of Iowa researchers say that the common fruit fly, Drosophila melanogaster, is an ideal model to study hearing loss in humans caused by loud noise. The reason: The molecular underpinnings to its hearing are roughly the same as with people.
The origin of cosmic rays in the universe has confounded scientists for decades. But a study by researchers using data from the IceCube Neutrino Observatory at the South Pole reveals new information that may help unravel the longstanding mystery of exactly how and where they are produced.
Astronomers using NASA's Chandra X-ray Observatory have taken a major step in explaining why material around the giant black hole at the center of the Milky Way Galaxy is extraordinarily faint in X-rays. This discovery holds important implications for understanding black holes.
The light-year-long knot of interstellar gas and dust, seen in this Hubble photo, resembles a caterpillar on its way to a feast. Harsh winds from extremely bright stars are blasting ultraviolet radiation at this 'wanna-be' star and sculpting the gas and dust into its long shape.

When a beating heart slips into an irregular, rhythm, the treatment is electric current from a pacemaker or defibrillator. But the electricity itself can cause pain, tissue damage and other side-effects. Now, researchers want to replace jolts with a gentler remedy: light.
Problems with a key group of enzymes called topoisomerases can have profound effects on the genetic machinery behind brain development and potentially lead to autism spectrum disorder (ASD), according to research announced today in the journal Nature. Scientists at the University of North Carolina School of Medicine have described a finding that represents a significant advance in the hunt for environmental factors behind autism and lends new insights into the disorder’s genetic causes.

Like volunteers handing out cups of energy drinks to marathon runners, specially engineered “helper cells” transplanted along with stem cells can dole out growth factors to increase the stem cells’ endurance, at least briefly, Johns Hopkins researchers report. Their study, published in the September issue of Experimental Neurology, is believed to be the first to test the helper-cell tactic, which they hope will someday help to overcome a major barrier to successful stem cell transplants.
Scientists have detected magmatic water — water that originates from deep within the Moon's interior — on the surface of the Moon. These findings, published in the August 25 issue of Nature Geoscience, represent the first such remote detection of this type of lunar water, and were arrived at using data from NASA’s Moon Mineralogy Mapper (M3).
