A chimpanzee’s intelligence is largely determined by its genes, while environmental factors may be less important than scientists previously thought, according to a Georgia State University research study.
NASA's Hubble Space Telescope has photographed an unusual structure 100,000 light-years long, which resembles a corkscrew-shaped string of pearls and winds around the cores of two colliding galaxies. The unique structure of the star spiral may yield new insights into the formation of stellar superclusters that result from merging galaxies and gas dynamics in this rarely seen process.
The discovery of a split-second burst of radio waves by scientists using the Arecibo radio telescope in Puerto Rico provides important new evidence of mysterious pulses that appear to come from deep in outer space.
As daily temperatures increase, so does the number of patients seeking treatment for kidney stones. In a study that may both reflect and foretell a warming planet’s impact on human health, a research team found a link between hot days and kidney stones in 60,000 patients in several U.S. cities with varying climates.
Physicists are pretty adept at controlling quantum systems and even making certain entangled states. JQI researchers are putting these skills to work to explore the dynamics of correlated quantum systems. Their recent results investigating how information flows through a quantum many-body system are published this week in the journal Nature (10.1038/nature13450), and in a second paper to appear in Physical Review Letters.
Although feelings are personal and subjective, the human brain turns them into a standard code that objectively represents emotions across different senses, situations and even people, reports a new study by Cornell University neuroscientist Adam Anderson.
A new study shows that some shark species may be able to cope with the rising salinity of Arctic waters that may come with rising temperatures.
The first global census of the Adélie penguin, long considered a key indicator species to monitor and understand the effects of climate change and fishing in the Southern Ocean, has revealed its population (3.79 million breeding pairs) to be 53 percent larger than previously estimated. By using high-resolution satellite imagery, Stony Brook University ecologist Heather Lynch, PhD, and conservation biologist Michelle LaRue, PhD, of the University of Minnesota, have applied a new method that permits regular monitoring of Adélie penguins across their entire breeding range, and by extension the health of the Southern Ocean ecosystem. Their findings are published in The Auk, Orinthological Advances.
After collectors found specimens of the prickly plant in 1974 and 1990, it was wrongly identified as three different species. Now a University of Utah botanist and colleagues identified the plant as a new, possibly endangered species named “from the heart” in Latin because it was found in Valentine, Texas.
An observatory run by the University of Utah found a “hotspot” beneath the Big Dipper emitting a disproportionate number of the highest-energy cosmic rays. The discovery moves physics another step toward identifying the mysterious sources of the most energetic particles in the universe.

A newly discovered planet is expanding astronomers’ notions of where Earth-like—and even potentially habitable—planets can form, and how to find them.
Johns Hopkins researchers have begun to connect the dots between a schizophrenia-linked genetic variation and its effect on the developing brain. As they report July 3 in the journal Cell Stem Cell, their experiments show that the loss of a particular gene alters the skeletons of developing brain cells, which in turn disrupts the orderly layers those cells would normally form.
Adults who have dyslexia are much more likely to report they were physically abused before they turned 18 than their peers without dyslexia, according to a new study from researchers at the University of Toronto and the University of North Carolina School of Medicine in Chapel Hill.
A team of researchers from the University of California, San Diego School of Medicine, Oregon Health & Science University (OHSU) and Salk Institute for Biological Studies has shown for the first time that stem cells created using different methods produce differing cells. The findings, published in the July 2, 2014 online issue of Nature, provide new insights into the basic biology of stem cells and could ultimately lead to improved stem cell therapies.
In chambers that mimic Mars’ conditions, University of Michigan researchers have shown how small amounts of liquid water could form on the planet despite its below-freezing temperatures.

Orgasms aren’t just good for your sexual relationship; they may also promote good communication. Results of a new study published in the latest edition of Communication Monographs reveal that in the aftermath of having experienced an orgasm, people are more likely to share important information with their partners. And, that communication is likely to be positive.
Emotional and behavioral problems show up even with low exposure to lead, and as blood lead levels increase in children, so do the problems, according to research funded by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health. The results were published online June 30 in the journal JAMA Pediatrics.

The politically expedient way to mitigate climate change is essentially no way at all, according to a comprehensive new study by University of Chicago climatologist Raymond Pierrehumbert.
For children, stress can go a long way. A little bit provides a platform for learning, adapting and coping. But a lot of it — chronic, toxic stress like poverty, neglect and physical abuse — can have lasting negative impacts. A team of University of Wisconsin-Madison researchers recently showed these kinds of stressors, experienced in early life, might be changing the parts of developing children’s brains responsible for learning, memory and the processing of stress and emotion.
Humans have a well-documented tendency to see winning and losing streaks in situations that, in fact, are random. But scientists disagree about whether the “hot-hand bias” is a cultural artifact picked up in childhood or a predisposition deeply ingrained in the structure of our cognitive architecture.
Signals from the immune system that help repel a common parasite inadvertently can cause a dormant viral infection to become active again, a new study shows.
While preferring silence to music from the West, chimpanzees apparently like to listen to the different rhythms of music from Africa and India, according to new research published by the American Psychological Association.
A new study in the July issue of Annals of Allergy, Asthma & Immunology examined 305 caregivers of children allergic to milk, egg, peanut or tree nut. The researchers were surprised to discover that milk and eggs, not peanuts, were the largest source of anxiety and worry.
Old World monkeys have undergone a remarkable evolution in facial appearance as a way of avoiding interbreeding with closely related and geographically proximate species, researchers from NYU and the University of Exeter have found. Their research provides the best evidence to date for the role of visual cues as a barrier to breeding across species.
Older veterans who have experienced a traumatic brain injury (TBI) are 60 percent more likely to later develop dementia than veterans without TBI, according to a study published in the June 25, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Scientists with Texas A&M AgriLife Research have found a “Trojan horse” way to deliver proteins into live human cells without damaging them. The finding, published in this month’s Nature Methods, is expected to be easily adopted for use in medical research to find cures and treatments for a wide range of diseases, according to the team’s lead scientist, Dr. Jean-Philippe Pellois, an associate professor of biochemistry at Texas A&M University.
The chemical makeup of wastewater generated by “hydrofracking” could cause the release of tiny particles in soils that often strongly bind heavy metals and pollutants, exacerbating the environmental risks during accidental spills, Cornell University researchers have found.
Imagine a world in which a consumer's real-time physical and emotional response helped to determine his/her experience of music, online ads or the temperature in the room. That may not be so far away -- a team of researchers has developed a flexible, wearable 20mm x 20mm polymer sensor that can directly measure the degree and occurrence of goose bumps, caused by sudden changes in body temperature or emotional states.
Physicians using body mass index (BMI) to diagnose children as obese may be missing 25 percent of kids who have excess body fat despite a normal BMI, which can be a serious concern for long-term health, according to a Mayo Clinic study published online today in Pediatric Obesity.
A new kind of imaging technique shows how exercise and diabetes drugs affect the amount of fat inside our bones, which could play roles in the health of our bones.
Some clover species have two forms, one of which releases cyanide to discourage nibbling by snails and insects and the other of which does not. A scientist at Washington University in St. Louis found that this "polymorphism" has evolved independently in six different species of clover, each time by the wholesale deletion of a gene. The clover species are in a sense predisposed to develop this trait, suggesting that evolution is not entirely free form but instead bumps up against constraints.
“A dropped item is immediately contaminated and can’t really be sanitized,” said Jorge Parada, MD, MPH, FACP, FIDSA, medical director of the Infection Prevention and Control Program at Loyola University Health System. “When it comes to folklore, the ‘five-second rule’ should be replaced with ‘When in doubt, throw it out.’ ”
Some people find it easier to be their 'true selves' online, a new study says, but posting too much information on Facebook doesn't get users the validation they seek.

Researchers at the University of California, San Diego School of Medicine have discovered a fundamental mechanism by which the brain maintains its internal balance. The mechanism, described in the June 22 advanced online publication of the journal Nature, involves the brain's most basic inner wiring and the processes that control whether a neuron relays information to other neurons or suppresses the transmission of information.
Vitamin D and calcium supplementation along with diet and exercise may prevent Type 2 diabetes in prediabetic individuals who have insufficient vitamin D in their bodies, a study from India suggests. The results were presented Saturday at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago.
Researchers have demonstrated for the first time in an animal model that maternal use of a class of antidepressants called selective serotonin reuptake inhibitors, or SSRIs, resulted in increased fat accumulation and inflammation in the liver of the adult offspring, raising new concerns about the long-term metabolic complications in children born to women who take SSRI antidepressants during pregnancy.
Researchers at Penn State and Shinshu University in Japan have developed a simple, scalable method of making graphene oxide (GO) fibers that are strong, stretchable and can be easily scrolled into yarns with strengths approaching that of Kevlar.
