Brain inflammation caused by chronic nerve pain alters activity in regions that regulate mood and motivation, suggesting for the first time that a direct biophysical link exists between long-term pain and the depression, anxiety and substance abuse seen in more than half of these patients, UC Irvine and UCLA researchers report.
In a study published today in ACS Central Science, a research team led by University of Wisconsin-Madison Chemistry Professor Timothy Bertram peels back the mysteries of the structures of tiny aerosol particles at the surface of the ocean. The work shows how the particles’ chemical composition influences their abilities to take in moisture from the air, which indicates whether the particle will help to form a cloud — a key to many basic problems in climate prediction.
A University of Maryland School of Social Work researcher joins with colleagues at William & Mary to probe a possible connection between fermented foods, which contain probiotics, and social anxiety symptoms.
Food wasted means money wasted, which can be an expensive problem especially in homes with financial constraints. A new study from the Cornell Food and Brand Lab and the Getulio Vargas Foundation, shows that the top causes of food waste in such homes include buying too much, preparing in abundance, unwillingness to consume leftovers, and improper food storage.
The witness on the stand says he saw the accused at the scene of the crime. Is he sure? How sure? The jury’s verdict could hinge on that level of certainty. Many decisions we make every day are influenced by our memories and the confidence we have in them. But very little is known about how we decide whether we can trust a memory or not. Cedars-Sinai researchers have identified a unique set of neurons in the medial temporal lobe, an area of the brain where memories and memory-based decisions are processed. They show that the activity of these neurons is indicative of the confidence by which a memory will be retrieved.
The 50 hospitals in the United States with the highest markup of prices over their actual costs are charging out-of-network patients and the uninsured, as well as auto and workers’ compensation insurers, more than 10 times the costs allowed by Medicare, new research suggests. It’s a markup of more than 1,000 percent for the same medical services.

Scientists in the STAR collaboration at the Relativistic Heavy Ion Collider, a particle accelerator exploring nuclear physics and the building blocks of matter at the U.S. Department of Energy's Brookhaven National Laboratory, have new evidence for what's called a "chiral magnetic wave" rippling through the soup of quark-gluon plasma created in RHIC's energetic particle smashups. The findings are described in a paper that will be highlighted as an Editors' Suggestion in Physical Review Letters.
When it comes to the three-horned dinosaur called the Triceratops, science is showing the ancient creatures might have been a little more complex than we thought. In fact, their teeth were far more intricate than any reptile or mammal living today.
A team of scientists have taken quantum teleportation – a method of communicating information from one location to another without having to physically move it – to a higher level by using certain high-dimensional states (which they dubbed “donut” states) for teleportation. Stony Brook University physicist Tzu-Chieh Wei, PhD, and colleagues nationally demonstrated that their method works, is more reliable than previous teleportation schemes, and could be a stepping stone toward building a quantum communications network. Their findings appear in Nature Communications.

Archaeologists at the University of Southampton have found evidence of an ancient gold trade route between the south-west of the UK and Ireland. A study suggests people were trading gold between the two countries as far back as the early Bronze Age (2500BC).
New research has revealed that parasitic ‘vampire’ plants that attach onto and derive nutrients from another living plant may benefit the abundance and diversity of surrounding vegetation and animal life.
An artificial intelligence system has reverse-engineered the regeneration mechanism of planaria, a common model in regenerative medicine. This is the first reported model of regeneration discovered by a non-human intelligence, and the first comprehensive model of planarian regeneration, which has long eluded human scientists.
In a breakthrough for computer vision and for bird watching, researchers and bird enthusiasts have enabled computers to achieve a task that stumps most humans—identifying hundreds of bird species pictured in photos.
What is it with cheating? Cheaters seem to have an immediate advantage over cooperators, but do they have an evolutionary advantage? A study published in Current Biology suggests the benefits of cheating change with its prevalence,in a population. Cheaters may succeed, for example, only when they are rare, and fail when they become so numerous they push out cooperators.
Physical activities, such as walking, as well as aerobics/calisthenics, biking, gardening, golfing, running, weight-lifting, and yoga/Pilates are associated with better sleep habits, compared to no activity, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania. In contrast, the study shows that other types of physical activity – such as household and childcare -- work are associated with increased cases of poor sleep habits. The full results of the study (Abstract #0246) will be presented during the poster session on Monday, June 8, at SLEEP 2015, the 29th annual meeting of the Associated Professional Sleep Societies LLC, June 6-10, in Seattle, WA.

A study of marine mammals finds that several once endangered species, including the humpback whale, the northern elephant seal and green sea turtles, have recovered and are repopulating their former ranges. But returning species create a new challenge: some people interpret the return of these animals as a hostile invasion. The study presents strategies for “lifting baselines” to help manage and celebrate recovering species.
New research shows that the close linkage between the physical properties of amino acids, the genetic code, and protein folding was likely the key factor in the evolution from building blocks to organisms when Earth’s first life was emerging from the primordial soup.

Prostate cancer is the second most common type of cancer in men and is predicted to result in an estimated 220,00 cases in the United States in 2015. In recent years, an emphasis has been placed on chemoprevention – the use of agents to prevent the development or progression of prostate cancer. A team of researchers led by Nagi B. Kumar, Ph.D., R.D., F.A.D.A. at Moffitt Cancer Center recently published results of a randomized trial that assessed the safety and effectiveness of the active components in green tea to prevent prostate cancer development in men who have premalignant lesions. The results will be presented at the 2015 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.
Dinosaurs grew as fast as your average living mammal, according to a research paper published by Stony Brook University paleontologist Michael D’Emic, PhD. The paper, to published in Science on May 29, is a re-analysis of a widely publicized 2014 Science paper on dinosaur metabolism and growth that concluded dinosaurs were neither ectothermic nor endothermic—terms popularly simplified as ‘cold-blooded’ and ‘warm-blooded’—but instead occupied an intermediate category.
