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.
Instead, women can sometimes take an earnings hit relative to their male colleagues when they go to work for a female manager.
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 this protein aberrantly activates growth-promoting genes in melanoma cells.

Often referred to as the "body clock", circadian rhythm controls what time of day people are most alert, hungry, tired or physically primed due to a complex biological process that is not unique to humans. Circadian rhythms, which oscillate over a roughly 24-hour cycle in adaptation to the Earth's rotation, have been observed in most of the planet's plants, animals, fungi and cyanobacteria, and are responsible for regulating many aspects of organisms' physiological, behavioral and metabolic functions.
When a new type of drug or therapy is discovered, double-blind randomized controlled trials (DBRCTs) are the gold standard for evaluating them. These trials, which have been used for years, were designed to determine the true efficacy of a treatment free from patient or doctor bias, but they do not factor in the effects that patient behaviors, such as diet and lifestyle choices, can have on the tested treatment.
With warming summer temperatures across Alaska, white spruce tree growth in Interior Alaska has declined to record low levels, while the same species in Western Alaska is growing better than ever measured before.
The findings are the result of a study led by University of Alaska Fairbanks School of Natural Resources and Extension researcher Glenn Juday, Claire Alix of the University of Paris 1 Pantheon-Sorbonne, and Tom Grant, formerly an adjunct faculty member at UAF. Their findings were recently published online by the journal Forest Ecology and Management.
Political partisanship is rooted in affective, physiological processes that cause partisans to toe the party line on policies and issues, regardless of policy content, according to a new paper.
Social psychologists have said that party identifiers are more inclined to agree with policy proposals that are proposed by their own party, independent of the content of the proposal. If the same proposal is issued by a competing party, they will be inclined to respond negatively to it. In other words, liberals and conservatives don't care about what is best for society, it has to be filtered through their beliefs to be legitimate.
Partnerships with multinational companies like Coca-Cola in child health programs can work to help save lives but decades of well-funded public relations campaigns against corporations by NGOs has turned letting companies fund programs into 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 diarrhea in remote parts of Zambia.
In a new study, older women who lived in places with higher air pollution had significantly reduced white matter in the brain. For the study, a research team took brain MRIs of 1403 women who were 71 to 89 years old and used residential histories and air monitoring data to estimate their exposure to air pollution in the previous 6 to 7 years.
The findings suggest that ambient particulate air pollutants may have a deleterious effect on brain aging.
New measures introduced by the UK government in April linking applications for residence permits to up-front payments for potential use of NHS hospital services, and proposals to further restrict access to NHS services for migrants, will not reduce the strain on NHS resources - and may end up costing more in the long run.
Some of the nation's largest businesses encourage employees to travel to large U.S. medical centers for complex elective surgical procedures. As part of these medical travel programs, companies negotiate lower prices for patients to receive high-quality surgical care at some of the nation's premier hospitals.
But many participants must travel long distances - sometimes hundreds of miles from home - to reach destination hospitals, meaning it can be difficult to return should complications arise.
Using Twitter and Google search trend data in the wake of the very limited U.S. Ebola outbreak of October 2014, a team of researchers from Arizona State University, Purdue University and Oregon State University have found that news media is extraordinarily effective in creating public panic.
Because only five people were ultimately infected yet Ebola dominated the U.S. media in the weeks after the first imported case, the researchers set out to determine mass media's impact on people's behavior on social media.
Following a decade of steady growth, use of bisphosphonates—medications that are effective for treating osteoporosis—declined in the United States by more than 50% from 2008 to 2012.
The sudden drop seemed to occur after media reports highlighted safety concerns, such as the development of certain fractures that occurred rarely in long-term users, despite the fact that the US Food and Drug Administration and the American Society of Bone and Mineral Research did not recommend any specific safety restrictions on bisphosphonates. The findings are published in the Journal of Bone and Mineral Research.
Put down that honey. Fructose, often in the form of table sugar, is not less harmful than glucose, according to Wilhelm Krek, professor for cell biology at ETH Zurich's Institute for Molecular Health Sciences.
Pet dogs may be humans' best friends in a new arena of life: cancer treatment, said University of Illinois veterinary clinical medicine professor Timothy Fan. Physiological similarities between dogs and humans, and conserved genetics between some dog and human cancers, can allow pet dogs to serve as useful models for studying new cancer drugs, he said.
In a meeting sponsored by the National Cancer Policy Forum of the National Academies' Institute of Medicine in Washington, D.C., Fan and 15 other experts in the field described the benefits of using pet dogs with naturally occurring (rather than laboratory-induced) tumors in early cancer drug trials.
It's been around for decades and it's probably in your diet soda - for a little while longer anyway. PepsiCo announced recently it was removing the artificial sweetener aspartame from its Diet Pepsi products in the U.S. starting in August.
The company cited consumer concerns about the chemical's safety.
So this week, Reactions answers the question, "Is aspartame safe?"
The prevalence of smoking among undergraduate nursing and physiotherapy students in Spain decreased from 29.3% in 2003 to 18.2% in 2013. Many of the students remained unaware of the link between smoking and diseases such as bladder cancer or the negative health effects of second-hand smoke, which points to a significant deficiency in undergraduate training.
The majority of nursing and physiotherapy students recognized that healthcare professionals were role models in society, noted Dr. Beatriz Ordás, lead author of the Journal of Advanced Nursing study.
A team of scientists and engineers at The University of Texas at Austin has identified the first sensor of the Earth's magnetic field in an animal, finding in the brain of a tiny worm a big clue to a long-held mystery about how animals' internal compasses work.
Animals as diverse as migrating geese, sea turtles and wolves are known to navigate using the Earth's magnetic field. But until now, no one has pinpointed quite how they do it. The sensor, found in worms called C. elegans, is a microscopic structure at the end of a neuron that other animals probably share, given similarities in brain structure across species. The sensor looks like a nano-scale TV antenna, and the worms use it to navigate underground.
