In an experiment designed to mimic the conditions deep inside the icy giant planets of our solar system, scientists were able to observe “diamond rain” for the first time as it formed in high-pressure conditions. Extremely high pressure squeezes hydrogen and carbon found in the interior of these planets to form solid diamonds that sink slowly down further into the interior.

Behavior experiments are useful tools to study brain function. Standard experiments to investigate behavior in popular lab animals such as fish, flies or mice however only incompletely mimic natural conditions. The understanding of behavior and brain function is thus limited. Virtual Reality (VR) helps in generating a more natural experimental environment but requires immobilization of the animal, disrupting sensorimotor experience and causing altered neuronal and behavioral responses. Researchers at the University of Freiburg, and the Max F. Perutz Laboratories (MFPL), a joint venture of the University of Vienna and the Medical University of Vienna, in collaboration with groups at the Research Institute of Molecular Pathology (IMP) and the MPI for Ornithology in Konstanz, have now developed a VR system for freely moving animals – FreemoVR – to overcome most of these limitations. Their findings are now published in Nature Methods.

A new study from Indiana University-Purdue University Indianapolis validates that the central core of the East Antarctic ice sheet should remain stable even if the West Antarctic ice sheet melts.

Sunbathers may want to avoid midnight snacks before catching some rays.

Biologists conducted the first large-scale experiment on a Superfund site using poplar trees fortified with a probiotic — or natural microbe — to clean up groundwater contaminated with trichloroethylene, or TCE.

UCLA researchers have discovered a new way to activate the stem cells in the hair follicle to make hair grow. The research, led by scientists Heather Christofk and William Lowry, may lead to new drugs that could promote hair growth for people with baldness or alopecia, which is hair loss associated with such factors as hormonal imbalance, stress, aging or chemotherapy treatment.

A new study shows that Instagram photos can be examined by a computer to successfully detect depressed people. The computer results are more reliable (70%) than the diagnostic success rate (42%) of general-practice doctors. The approach promises a new method for early screening of mental health problems through social media.

Scientists have created the most accurate map of the structure of dark matter in the Universe, supporting the theory that dark energy and dark matter make up most of the Universe.

A new analysis of genome sequences from the ancient Minoans and Mycenaeans by HHMI investigator and colleagues offers insight into the origins of these Bronze Age cultures.

Human-caused habitat loss looms as the greatest threat to some North American breeding birds over the next few decades. The problem will be most severe on their wintering grounds, according to a new study published in the journal Global Change Biology.

In a first-of-its-kind analysis, Northwestern University astrophysicists have discovered that up to half of the matter in our Milky Way galaxy may come from distant galaxies. As a result, each one of us may be made in part from extragalactic matter. Using supercomputer simulations, the researchers found an unexpected mode for how galaxies acquired matter: intergalactic transfer. Supernova explosions eject copious amounts of gas from galaxies, causing atoms to be transported from one galaxy to another via powerful galactic winds.

Why use regular sunscreen when you can apply a DNA film to your skin? Researchers at Binghamton University, State University of New York have developed a coating made out of DNA that gets better at protecting skin from Ultraviolet light the more you expose it to the sun, and it also keeps your skin hydrated.

Just as “Shark Week” is gearing up, researchers have discovered a new species of shark 17 years in the making. Like finding a needle in a haystack, it was well worth the wait as this elusive creature is yet to be seen in the wild.

In saliva, scientists have found hints that a “ghost” species of archaic humans may have contributed genetic material to ancestors of people living in Sub-Saharan Africa today. The research adds to a growing body of evidence suggesting that sexual rendezvous between different archaic human species may not have been unusual.

While photographing Mars, NASA's Hubble Space Telescope captured a cameo appearance of the tiny moon Phobos on its trek around the Red Planet. Hubble took 13 separate exposures over 22 minutes to create a time-lapse video showing the moon's orbital path.

People have scoffed that 3-D printers are simply toys themselves. But they probably didn't realize how much money is made off playthings. Do-it-yourself (DIY) manufacturing—making goods at home with a 3-D printer using open source designs from a free online repository—has a multimillion-dollar impact on the overall toy industry.

Humans have created 8.3 billion metric tons of plastics since large-scale production of the synthetic materials began in the early 1950s, and most of it now resides in landfills or the natural environment, according to a study published today in the journal Science Advances.

The University of Utah’s J. Marriott Library created an interactive, geospatial archive depicting the story of Utah radioactive fallout related to atmospheric nuclear testing at the Nevada Test Site.

New biological information gleaned from the red vizcacha rat, a native species of Argentina, demonstrates how genomes can rapidly change in size. Researchers from McMaster University set out to study this particular species because its genome, or its complete set of DNA, is the largest of all mammals, and appears to have increased in size very rapidly.

Unmitigated climate change will make the United States poorer and more unequal, according to a new study published today in the journal Science. The poorest third of counties could sustain economic damages costing as much as 20 percent of their income if warming proceeds unabated. States in the South and lower Midwest, which tend to be poor and hot already, will lose the most, with economic opportunity traveling northward and westward. Colder and richer counties along the northern border and in the Rockies could benefit the most as health, agriculture and energy costs are projected to improve.
