Researchers have demonstrated that people with the highest genetic propensity are over two and a half times as likely to be treated in a psychiatric hospital for depression compared to people with the lowest propensity. This knowledge could be utilized to strengthen preventative efforts for those who are at risk.

Crustacean's dazzling light displays
Evolution is a rich and dynamic process. Species respond to pressures in a variety of ways, most of which reduce to finding food, avoiding becoming someone else's food and attracting a mate. To solve that last one the animal kingdom is replete with fantastic, bizarre and mesmerizing adaptions. The bioluminescent courtship displays of ostracods may encapsulate all three.

Gardens in urban areas can harbor a remarkable diversity of species. This has been found by researchers in a field study carried out with the support of private garden owners from the Basel region. Furthermore, the research team shows that nature-friendly garden management and design can largely compensate for the negative effects of urbanization on biodiversity.

Prairie strips transform farmland conservation
Modern agriculture's outputs can be measured both in dollars paid in the market and also in non-market costs, known as externalities. Soil, nutrients, groundwater, pollinators, wildlife diversity, and habitat (among other things) can be lost when crop yields are maximized. Now it appears that prairie strips have an extraordinary power to change this pattern.

In a first-of-its-kind study, researchers have determined the underlying anatomical cause of certain symptoms of schizophrenia, then ameliorated them with non-invasive brain stimulation. The scientists reported that these symptoms arise from a breakdown in a network between the brain's prefrontal cortex and the cerebellum, and that non-invasive brain stimulation restored network function, which in turn improved schizophrenia's most debilitating symptoms.

Poor sleep at night, more pain the next day
After one night of inadequate sleep, brain activity ramps up in pain-sensing regions while activity is scaled back in areas responsible for modulating how we perceive painful stimuli. This finding provides the first brain-based explanation for the well-established relationship between sleep and pain.

Predicting gentrification in order to prevent it
This first-of-its-kind study offers a new model to identify the U.S. neighborhoods most vulnerable to gentrification. The study reveals the factors with the greatest influence on gentrification and examines the roles that government and policy can proactively play in limiting its impacts. The research serves as a roadmap to implement proven anti-gentrification strategies before it's too late.

Earthquake in super slo-mo
A big earthquake occurred south of Istanbul in the summer of 2016, but it was so slow that nobody noticed. The earthquake, which took place at mid-crustal depth, lasted more than fifty days. Only a novel processing technique applied to data from special borehole strainmeter instruments allowed researchers to identify the ultra-slow quake below the Sea of Marmara.

Cattle urine's planet-warming power can be curtailed with land restoration
The exceptional climate-altering capabilities of cattle are mainly due to methane, which they blast into the atmosphere during their daily digestive routine. Cattle urine is a lesser-known climate offender. It produces nitrous oxide (N2O), which has warming power far greater than that of carbon dioxide (CO2), the main driver of global warming. A new study shows that these N2O emissions can be significantly curbed by healthy cattle pastures.

Common test for mental health understanding is biased, study finds
The National Institute for Mental Health recommends a test, called the Reading the Mind in the Eyes Task (RMET), for assessing a person's mental health understanding -- that is a patient's ability to understanding what other people are thinking and feeling. But there's a problem. Using data from more than 40,000 people, a new study concludes that the test is deeply flawed. It relies too heavily on a person's vocabulary, intelligence, and culturally-biased stimuli.
