Researchers at Monash University have found physical differences in the brains of people who respond emotionally to others' feelings, compared to those who respond more rationally, in a study published in the journal NeuroImage. The work, led by Robert Eres from the University's School of Psychological Sciences, pinpointed correlations between grey matter density and cognitive and affective empathy. The study looked at whether people who have more brain cells in certain areas of the brain are better at different types of empathy. "People who are high on affective empathy ...

UNIVERSITY OF CALIFORNIA, BERKELEY'S HAAS SCHOOL OF BUSINESS--Working women are "leaning in" and supporting more females in leadership roles, but a new study finds that having a female manager doesn't necessarily equate to higher salaries for female employees. In fact, women can sometimes take an earnings hit relative to their male colleagues when they go to work for a female manager. "Agents of Change or Cogs in the Machine? Re-examining the Influence of Female Managers on the Gender Wage Gap"(American Journal of Sociology, forthcoming) is co-authored by Sameer B. Srivastava, ...

This news release is available in German. Researchers have used ultra-short pulses of X-rays to film shock waves in diamonds. The study headed by DESY scientists opens up new possibilities for studying the properties of materials. Thanks to the extremely bright and short X-ray flashes, the researchers were able to follow the rapid, dynamic changes taking place in the shock wave with a high spatial as well as a high temporal resolution. The team around DESY physicist Prof. Christian Schroer is presenting its results in the journal Scientific Reports. "With our experiment ...

In the current context of Global Change, sustainable and responsible exploitation of the Oceans can be realised only through a deep understanding of the Ocean processes and of the associated ecosystems spanning every latitude of Planet Earth. This is the key concept advocated by a new position paper from the European Science Foundation. Sailing through Changing Oceans analyses long-term, mid-term and short-term climatic changes and associates a number of key processes and impacts from Antarctica to the Arctic via the Atlantic, which highly affect ecosystems and need to ...

National Institutes of Health (NIH) researchers and their colleagues have developed a "placenta-on-a-chip" to study the inner workings of the human placenta and its role in pregnancy. The device was designed to imitate, on a micro-level, the structure and function of the placenta and model the transfer of nutrients from mother to fetus. This prototype is one of the latest in a series of organ-on-a-chip technologies developed to accelerate biomedical advances. The study, published online in the Journal of Maternal-Fetal & Neonatal Medicine, was conducted by an interdisciplinary ...

OTTAWA & TORONTO - Jessie is a five-year-old girl who doesn't like foods with much texture or flavour. She prefers to eat foods that don't require lots of chewing, like soup, pasta, or oatmeal. Jessie has difficulty eating a range of foods and her mother struggles daily with getting her to consume the nutrients she needs to grow and thrive. Jessie is the smallest child in her class and has been severely underweight for two years. Jason is a 10-year-old boy who was not a picky eater at all, until he nearly choked on a hot dog eight months ago. The hot dog dislodged and ...

After collecting data on a leukemia-affected family for nearly a decade, Children's Hospital of Michigan, Detroit Medical Center (DMC), Hematologist and Wayne State University School of Medicine Professor of Pediatrics Madhvi Rajpurkar, M.D., joined an international team of genetic researchers in an effort to track down a mutation partly responsible for causing the disease. Their findings, recently published in one of the world's leading science journals, have "major implications" for better understanding the genetic basis of several types of cancer, including leukemia. Says ...

The song of the male nightingale tells females how good a father he will be, according to research published in the open access journal BMC Evolutionary Biology. The study shows that better singers will feed their offspring more often, and that they advertise this to potential mates by singing in a more orderly way through repeating song sequences, and using more variable song, including many different 'buzz', 'whistle' and 'trill' songs. In around 80% of all bird species, males play a key role in raising their young. Male nightingales feed the female during incubation, ...

The recent craze for human breast milk amongst certain fitness communities, fetishists and chronic disease sufferers is ill advised say the authors of an editorial published today by the Journal of the Royal Society of Medicine. There is a lucrative online market for adult buyers of human breast milk, with websites and forums describing it as a 'clean' super food that can lead to gains in the gym, and even help with erectile dysfunction and cancer. There are claims that it is more digestible and contains positive immune building properties. The authors, led by Dr Sarah ...

Partnerships with multinational companies in child health programmes can work to help save lives, write the co-founders of charity ColaLife in The BMJ this week. But an academic argues that connections between multinational companies and child health projects present an ethical minefield. ColaLife, a charity formed by British couple Simon and Jane Berry, worked with Coca-Cola to learn about the distribution channels the company uses in developing countries. With this knowledge, they devised a system to ensure life saving treatments reach children with diarrhoea in remote ...

Up to 22 percent of surgical patients experience unexpected complications and must be readmitted for post-operative care. A study led by the University of Utah suggests that returning to the same hospital is important for recovery. Readmission to a different hospital was associated with a 26 percent increased risk for dying within 90 days. The results, published in The Lancet, have implications for patients who take part in domestic medical tourism programs. Some of the nation's largest businesses encourage employees to travel to large U.S. medical centers for complex ...

Patients rehospitalized with complications after major surgery are 26% more likely to survive if they return to the hospital where they had their operation compared to those readmitted to a different hospital, according to a national study involving over 9 million Medicare patients in the USA, published in The Lancet. The findings stand in contrast to current health policies that aim to regionalise major surgical procedures into high volume centres of excellence. "With up to one in four patients rehospitalized following complex surgery, our results could potentially ...

In The BMJ this week, two doctors criticize Australia for passing legislation that may be used to silence doctors working with asylum seekers. The Border Force Act 2015 says that from July 2015 contracted workers including doctors, nurses, and other healthcare professionals face a prison sentence of up to two years for blowing the whistle on substandard medical care given to asylum seekers in detention centres. Dr. David Berger at Broome Hospital in Western Australia, argues that the only reason to suppress doctors in this way, 'is to avoid embarrassing revelations ...

WHAT: Researchers funded by the National Institutes of Health (NIH) have identified a new immune disorder--DOCK2 deficiency--named after the mutated gene responsible for the disease. An international team of collaborators studied five children, four boys and one girl, from different ethnic backgrounds who had experienced debilitating infections early in life. The children were diagnosed with combined immunodeficiency (CID), which refers to a group of inherited disorders distinguished by defects in immune system cells called T cells. CIDs also may affect other cells of ...

WASHINGTON, June 17 --- The value of the tax exemption provided to non-profit private hospitals in return for 'charity care and community benefit' nearly doubled over a nine-year period, climbing from an estimated $12.6 billion in 2002 to $24.6 billion dollars by 2011, according to a study funded by the Robert Wood Johnson Foundation and led by researchers at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University. This growth in the value of the tax exemption underscores taxpayer interest in how hospitals allocate their community ...

MAYWOOD, Ill. - A genetic disorder called neurofibromatosis (NF) causes benign tumors to grow on the brain, spinal cord, and other parts of the nervous system. There are no effective drugs to prevent or reverse NF. But increasing scientific knowledge has allowed for better clinical management and fewer complications, resulting in a higher quality of life for neurofibromatosis patients, NF specialists report in the Journal of Neuropsychiatry and Clinical Neurosciences. Pediatric neurologist and NF specialist Nikolas Mata-Machado, MD, of Loyola University Medical Center, ...

Like homing pigeons, humans have a nose for navigation because our brains are wired to convert smells into spatial information, new research from the University of California, Berkeley, shows. While humans may lack the scent-tracking sophistication of, say, a search-and-rescue dog, we can sniff our way, blindfolded, toward a location whose scent we've smelled only once before, according to the UC Berkeley study published today (June 17) in the journal PLOS ONE. Similar investigations have been conducted on birds and rodents, but this is the first time smell-based navigation ...

(New York, June 17, 2015) Melanoma patients with high levels of a protein that controls the expression of pro-growth genes are less likely to survive, according to a study led by researchers at Icahn School of Medicine at Mount Sinai and published online in the journal Molecular Cell. The research team found that the protein, called H2A.Z.2, promotes the abnormal growth seen in melanoma cells as they develop into difficult-to-treat tumors. H2A.Z.2 is part of the chromosome structure that packages genes, and has the ability to switch them on off. Having high levels of ...

Men with an elevated, genetically inherited risk for prostate cancer could be routinely identified with a simple blood or urine test, scientists at UC San Francisco and Kaiser Permanente Northern California have concluded, potentially paving the way to better or earlier diagnosis. The study, which compared 7,783 men with prostate cancer to 38,595 men without the disease, is available online and will be published in an upcoming issue of the journal Cancer Discovery. The new study is one of the first to come out of the collaboration between UCSF and Kaiser Permanente ...

A typical computer chip includes millions of transistors connected with an extensive network of copper wires. Although chip wires are unimaginably short and thin compared to household wires both have one thing in common: in each case the copper is wrapped within a protective sheath. For years a material called tantalum nitride has formed protective layer in chip wires. Now Stanford-led experiments demonstrate that a different sheathing material, graphene, can help electrons scoot through tiny copper wires in chips more quickly. Graphene is a single layer of carbon ...

Metastatic colorectal cancer patients tend to live longer when they respond to the first line of chemotherapy their doctors recommend. To better predict how patients will respond to chemotherapy drugs before they begin treatment, researchers at University of California, San Diego School of Medicine conducted a proof-of-principle study with a small group of metastatic colorectal cancer patients. The results, published June 17 in PLOS ONE, revealed two genes that could help physicians make more informed treatment decisions for patients with this disease. Metastatic colorectal ...

People with lower educational levels and incomes are less likely to know about yoga, acupuncture, natural products and chiropractic medicine, according to a new study from San Francisco State University. Studies on the use of complementary and alternative medicine (CAM) have typically focused on learning more about who use these types of practices and why. Less is known about trends among those who do not partake, which inspired new research by Professor of Health Education Adam Burke, published in PLOS ONE on June 17. "It's very important to know why somebody is not ...

Higher consumption of dietary trans fatty acids (dTFA), commonly used in processed foods to improve taste, texture and durability, has been linked to worsened memory function in men 45 years old and younger, according to a University of California, San Diego School of Medicine study published online on June 17 in PLOS ONE. Researchers evaluated data from 1,018 men and women who were asked to complete a dietary survey and memory test involving word recall. On average, men aged 45 and younger recalled 86 words; however, for each additional gram of trans fats consumed daily, ...

Visitation at U.S. National Parks may potentially increase with increasing temperature in temperate areas, but may decrease with temperatures rising over 80 degrees Fahrenheit, according to a study using future climate and visitation modeling scenarios published June 17 in the open-access journal PLOS ONE by Nicholas Fisichelli and colleagues from U.S. National Park Service. Climate change may affect not only natural and cultural resources within protected areas, but also park tourism. To assess the relationship between climate and park visitation, the authors of this ...
