The study, led by Professor Simone Shamay-Tsoory of the University of Haifa found that, in addition to gender, differences in empathy between people is related to sexual preference and, therefore, this orientation is important when assessing differences in empathy among people
Chewing, breathing, and other regular bodily functions that we undertake “without thinking” actually do require the involvement of our brain, but the question of how the brain programs such regular functions intrigues scientists. Arlette Kolta, a professor at the University of Montreal’s Faculty of Dentistry, has shown that astrocytes play a key role. Astrocytes are star-shaped glial cells in our brain. Glial cells are not neurons – they play a supporting role.
The study followed almost 140,000 adults aged 35 to 70 over four years in 17 countries. Their muscle strength was measured using a handgrip dynamometer. They were taking part in the institute’s Prospective Urban-Rural Epidemiology (PURE) study.
Secondhand exposure to cannabis smoke under “extreme conditions,” such as an unventilated room or enclosed vehicle, can cause nonsmokers to feel the effects of the drug, have minor problems with memory and coordination, and in some cases test positive for the drug in a urinalysis. Those are the findings of a Johns Hopkins University School of Medicine study, reported online this month in the journal Drug and Alcohol Dependence.
An international team, including archaeologists from the University of Southampton, has found evidence suggesting leprosy may have spread to Britain from Scandinavia.

An international team of scientists has designed and tested a magnetic shield that is the first to achieve an extremely low magnetic field over a large volume. The device provides more than 10 times better magnetic shielding than previous state-of-the art shields. The record-setting performance makes it possible for scientists to measure certain properties of fundamental particles at higher levels of precision -- which in turn could reveal previously hidden physics and set parameters in the search for new particles.
To maximize such benefits as conserved biodiversity and sustained livelihoods, ecological restoration should increase ecological integrity, be sustainable in the long term, be informed by the past and future, and benefit and engage society.
Expansion of cattle pastures has led to the destruction of huge swaths of rain forest in Brazil, home to the world’s largest herd of commercial beef cattle. But a new study led by the University of Wisconsin-Madison’s Holly Gibbs shows that market-driven “zero deforestation agreements” have dramatically influenced the behavior of ranchers and the slaughterhouses to which they sell.
Citizen scientists tracking backyard bird feeders helped scientists pinpoint the climate forces that likely set the stage for boreal bird irruptions in which vast numbers of northern birds migrate far south of their usual winter range. The discovery could make it possible to predict the events more than a year in advance.
Salk scientists find a single molecule that controls the fate of mature sensory neurons
New research, led by the University of Southampton, has questioned the role played by ocean acidification, produced by the asteroid impact that killed the dinosaurs, in the extinction of ammonites and other planktonic calcifiers 66 million years ago.
A survey of more than 1,000 U.S. adults has found that misperceptions about miscarriage and its causes are widespread. Results of the survey, conducted by researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Health System, show that feelings of guilt and shame are common after a miscarriage and that most people erroneously believe that miscarriages are rare. The findings were published online today in the journal Obstetrics & Gynecology.
Over nearly 15 years spent studying ticks, Indiana University's Keith Clay has found southern Indiana to be an oasis free from Lyme disease, the condition most associated with these arachnids that are the second most common parasitic disease vector on Earth. He has also seen signs that this low-risk environment is changing, both in Indiana and in other regions of the U.S.
Karen Kramer, an associate professor of anthropology, published a study in the Journal of Human Evolution titled, “When Mothers Need Others: Life History Transitions Associated with the Evolution of Cooperative Breeding.” Her research examines how mothers underwent a remarkable transition from the past – when they had one dependent offspring at a time, ended support of their young at weaning and received no help from others – to the present, when mothers often have multiple kids who help rear other children.
Archaeologists from the University of York have played a key role in Anglo-Danish research which has suggested the dawn of the Viking Age may have been much earlier – and less violent – than previously believed.

When highly educated, dual-career couples have their first child, both spouses think the baby increases their workloads by equal amounts – but a new study suggests that’s not true.
To put the massive range of the electromagnetic spectrum into perspective, this image links wavelengths to the ocean, from blue whales to water molecules.
When it comes to rewards and punishments, which is more effective — the carrot or the stick? A simple experiment devised at Washington University in St. Louis suggests that punishments are more likely to influence behavior than rewards. The results, which stem from a study involving 88 students at the university, are available online in the journal Cognition.
Some 9 million American families lost their homes to foreclosure during the late 2000s housing bust, driving many to economic ruin and in search of new residences. Hardest hit were black, Latino, and racially integrated neighborhoods, according to a new Cornell University analysis of the crisis.
Researchers from Berkeley Lab and the University of Hawaii at Manoa have shown for the first time that cosmic hot spots, such as those near stars, could be excellent environments for the creation of molecular precursors to DNA.
In a synergy between the Hubble and Spitzer space telescopes, and the giant W. M. Keck Observatory, astronomers have set a new distance record to the farthest redshift-confirmed galaxy. It is so far away the light we receive left the galaxy over 13 billion years ago, and it is just arriving now. The new observations underline the very exciting discoveries that NASA's James Webb Space Telescope will enable when it is launched in 2018.
The onion, a humble root vegetable, is proving its strength outside the culinary world -- in an artificial muscle created from onion cells. Unlike previous artificial muscles, this one, created by researchers from National Taiwan University, can either expand or contract to bend in different directions depending on the driving voltage applied. The finding is published this week in the journal Applied Physics Letters.
Conventional semiconductor detectors made from germanium and silicon are standard equipment in nuclear physics, but are less useful in many emerging applications because they require low temperatures to operate. In recent years, scientists have been seeking new semiconductor materials to develop high-performance radiation detectors that can operate at room temperature, and now researchers from Oak Ridge National Laboratory think they have a good candidate material: a compound called thallium sulfide iodide.
Although the human ability to write evolved from our ability to speak, writing and talking are now such independent systems in the brain that someone who can’t write a grammatically correct sentence may be able say it aloud flawlessly.
They may not be on Facebook or Twitter, but dolphins do, in fact, form highly complex and dynamic networks of friends, according to a recent study by scientists at Harbor Branch Oceanographic Institute at Florida Atlantic University. Dolphins are known for being highly social animals, and a team of researchers at HBOI took a closer look at the interactions between bottlenose dolphins in the Indian River Lagoon (IRL) and discovered how they mingle and with whom they spend their time.
People with depression or bipolar disorder often feel their thinking ability has gotten “fuzzy”, or less sharp than before their symptoms began. Now, researchers have shown in a large study that effect is indeed real – and rooted in brain activity differences that show up on advanced brain scans.
Researchers have uncovered a unique connection between diabetes and Alzheimer’s disease, providing further evidence that a disease that robs people of their memories may be affected by elevated blood sugar.
