In a new study featured in the National Communication Association’s Journal of Applied Communication Research, authors Stacy Tye-Williams and Kathleen J. Krone identify and re-imagine the paradox of workplace bullying advice. They interviewed 48 individuals from a variety of occupations and found that targets of workplace bullying frequently offered advice they had received to other targets, despite believing that the advice either made no difference or had made their own situations worse.
When geologists went in search for evidence of ancient tsunamis along Southern California’s coastal wetlands, they found something else. Their discoveries have implications for seismic hazard and risk assessment in coastal Southern California.
In a new study, researchers at the University of California San Diego School of Medicine, University of Cyprus and Stanford University map the complex biological cascade caused by MIA: the expression of multiple genes involved in autism are turned up or down by MIA, affecting key aspects of prenatal brain development that may increase risk for atypical development later in life.
Standard antidepressant medications don’t work for everyone, and even when they do they are slow to kick in. In an effort to find better depression treatments, researchers at University of California San Diego School of Medicine discovered that inhibiting an enzyme called Glyoxalase 1 (GLO1) relieves signs of depression in mice. Moreover, inhibiting GLO1 worked much faster than the conventional antidepressant Prozac.
The research may help explain why people of color are disproportionately affected by fatal pedestrian crashes.
More than 50 million years ago, when the Earth experienced a series of extreme global warming events, early mammals responded by shrinking in size. While this mammalian dwarfism has previously been linked to the largest of these events, research led by the University of New Hampshire has found that this evolutionary process can happen in smaller, so-called hyperthermals, indicating an important pattern that could help shape an understanding of underlying effects of current human-caused climate change.
In a small-scale study of women with previously diagnosed mood disorders, Johns Hopkins researchers report that lower levels of the hormone allopregnanolone in the second trimester of pregnancy were associated with an increased chance of developing postpartum depression in women already known to be at risk for the disorder.
Researchers in Italy hope to measure Earth’s rotation using a laser-based gyroscope housed deep underground, with enough experimental precision to reveal measurable effects of Einstein’s general theory of relativity. The ring laser gyroscope technology enabling these Earth-based measurements provide, unlike those made by referencing celestial objects, inertial rotation information, revealing fluctuations in the rotation rate from the grounded reference frame. The group discusses their work in this week’s Review of Scientific Instruments.
NASA's Hubble Space Telescope has found that the black hole at the center of our Milky Way galaxy ate its last big meal about 6 million years ago, when it consumed a large clump of infalling gas. After the meal, the engorged black hole burped out a colossal bubble of gas weighing the equivalent of millions of suns, which now billows above and below our galaxy's center.
Men with longer exposure to the drugs finasteride and dutasteride had a higher risk of getting persistent erectile dysfunction than men with less exposure, reports a new study. The persistent erectile dysfunction continued despite stopping these drugs, in some cases for months or years. Prior to the study, there was no strong evidence the drugs cause sexual problems that continue after men stop taking them or that taking these drugs for a longer time increases the chance of experiencing sexual problems.
Researchers at the University of Iowa have proposed a new approach to sampling materials with weak or no magnetic fields. The method could help advance research in a host of fields, from computing to MRI machines. The results were published in the journal “Physical Review Letters.”
Feedbacks of clouds on climate change strongly influence the magnitude of global warming.
Researchers have developed a new way to identify and sort stem cells that may one day allow clinicians to restore vision to people with damaged corneas using the patient’s own eye tissue.
Iron particles generated by cities and industry are being dissolved by man-made air pollution and washed into the sea – potentially increasing the amount of greenhouse gases that the world’s oceans can absorb, a new study suggests.
Dog walkers want their dogs to have fun, freedom and space to enact their ‘dog-ness’ when they go for a walk, a new study from Leeds Beckett University shows.
