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.
