Research into lethal wounds found on a human skull may indicate one of the first cases of murder in human history—some 430,000 years ago—and offers evidence of the earliest funerary practices in the archaeological record.
A new study, by scientists from the University of Southampton and National Oceanography Centre (NOC), implies that the global climate is on the verge of broad-scale change that could last for a number of decades.
Astronomers using the Hubble Space Telescope have discovered for the first time a rear-end collision between two high-speed knots of ejected matter from a supermassive black hole. This discovery was made while piecing together a time-lapse movie of a plasma jet blasted from a supermassive black hole inside galaxy 3C 264, located 260 million light-years from Earth in the constellation Leo.
Cannabis plus alcohol is one of the most frequently detected drug combinations in car accidents, yet the interaction of these two compounds is still poorly understood. A study appearing online today in Clinical Chemistry, the journal of AACC, shows for the first time that the simultaneous use of alcohol and cannabis produces significantly higher blood concentrations of cannabis’s main psychoactive constituent, Δ9-tetrahydrocannabinol (THC), as well as THC’s primary active metabolite, 11-hydroxy-THC (11-OH-THC), than cannabis use alone.

The microbiome of a toddler’s gut may influence their behavior, a new study suggests. Scientists found correlations between temperament and the presence of specific types of intestinal bacteria in both girls and boys. The researchers aren’t looking for a way to help parents modify the ‘terrible twos,’ but for clues about how - and where - chronic illnesses like obesity, asthma, allergies and bowel diseases start.
The Millennium Drought in southeastern Australia forced Greater Melbourne, a city of 4.3 million people, to successfully implement innovations that hold critical lessons for water-stressed regions around the world, according to findings by UC Irvine and Australian researchers.

A team including scientists from Albert Einstein College of Medicine and the U.S. Army Medical Research Institute of Infectious Diseases has identified the molecular “lock” that the deadly Ebola virus must pick to gain entry to cells. The findings, made in mice, suggest that drugs blocking entry to this lock could protect against Ebola infection.
Air pollution regulations issued by the U.S. Environmental Protection Agency are estimated to save thousands of lives annually. A new study by researchers at Indiana University says these estimates are more uncertain than commonly believed.
New UK research has challenged the assumption that people with rheumatoid arthritis always take their medication as prescribed.
Attitudes and beliefs about CAM were found to be a better predictor of CAM usage than socio-demographic factors alone – such as race, sex, or education – which are often used to describe CAM users but stop short of fully explaining what drives people to use them.

Reporting on their study with lab-grown human cells, researchers at The Johns Hopkins University and the University of Maryland say that blocking a second blood vessel growth protein, along with one that is already well-known, could offer a new way to treat and prevent a blinding eye disease caused by diabetes.
In a new twist on the use of DNA in nanoscale construction, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators put synthetic strands of the biological material to work in two ways: They used ropelike configurations of the DNA double helix to form a rigid geometrical framework, and added dangling pieces of single-stranded DNA to glue nanoparticles in place.
Madagascar is home to extraordinary biodiversity, but in the past few decades, the island’s forests and associated biodiversity have been under greater attack than ever. Rapid deforestation is affecting the biotopes of hundreds of species, including the panther chameleon, a species with spectacular intra-specific colour variation. A new study by Michel Milinkovitch, professor of genetics, evolution, and biophysics at the University of Geneva (UNIGE), led in close collaboration with colleagues in Madagascar, reveals that this charismatic reptilian species, which is only found in Madagascar, is actually composed of eleven different species. The results of their research appear in the latest issue of the Molecular Ecology journal. They also discuss the urgent need to protect Madagascar’s habitats.
This new result has allowed researchers to determine the reason behind a large discrepancy in the data between two different methods used to measure the proton’s electric form factor.
It looks like a Slinky suspended in motion. Yet this photonics advancement – called a metamaterial hyperlens – doesn’t climb down stairs. Instead, it improves our ability to see tiny objects.
Psychoacoustics identifies five basic types of emotional speech: angry, fearful, happy, sad and neutral. In order to fully understand what’s happening with speech perception, a research team at the University of Texas at Austin studied how depressed individuals perceive these different kinds of emotional speech in multi-tonal environments. They will present their findings at the 169th ASA meeting, held this week in Pittsburgh.
Astronomers have spent decades trying to determine the oddball behavior of an aging star nicknamed "Nasty 1" residing in our Milky Way galaxy. Looking at the star using NASA's Hubble Space Telescope, astronomers had expected to see a bipolar outflow of twin lobes of gas from the star. The astronomers were surprised, however, to find a pancake-shaped disk of gas encircling the star. The vast disk is nearly 1,000 times the diameter of our solar system.
New research from UAB shows that high-heeled-shoe-related injuries doubled between 2002 and 2012. The frequency and severity of those injuries were sufficient to make the investigators suggest that wearing the appropriate shoes for the appropriate occasion and being aware of one’s surroundings are good ideas.
Marketers and advertisers who default to the “thin ideal” – the belief that thinner is better – could be alienating up to 70 percent of their audience, said James Roberts, Ph.D., The Ben H. Williams Professor of Marketing in Baylor’s Hankamer School of Business.

Inducing a sense of awe in people can promote altruistic, helpful and positive social behavior, according to new research led by UC Irvine psychologist Paul Piff.
Researchers at the University of Colorado suggest that the portion of the brain devoted to hearing can become reorganized even with early-stage hearing loss, and may play a role in cognitive decline. They have applied fundamental principles of neuroplasticity, the ability of the brain to forge new connections, to determine the ways it adapts to hearing loss, as well as the consequences of those changes, and their findings will be presented at ASA’s 169th meeting.
Inducing a sense of awe in people can promote altruistic, helpful and positive social behavior according to research published by the American Psychological Association.
Estrangement between a mother and an adult child is more common than people might think, says an Iowa State researcher. A new study, published in the Journal of Marriage and Family, found estrangement is often the result of a difference in values.
Modern lifestyles have made our bones lighter weight than our hunter-gatherer ancestors. A study of the bones of hundreds of humans who lived during the past 33,000 years in Europe finds the rise of agriculture and a corresponding fall in mobility drove the change, rather than urbanization, nutrition or other factors.

Screening to identify Type 2 diabetes followed by early treatment could result in substantial health benefits, according to new research that combined large scale clinical observations and innovative computer modelling.
Studies have shown that individuals with hearing loss or who are listening to degraded speech – think of a loud room -- have greater difficulty remembering and processing the spoken information than individuals who heard more clearly. Now researchers are investigating whether listening to accented speech similarly affects the brain's ability to process and store information. Their preliminary results suggest that foreign-accented speech, even when intelligible, may be slightly more difficult to recall than native speech.
