Teens and young adults are making use of social networking sites and mobile technology to express suicidal thoughts and intentions as well as to reach out for help, two studies suggest.
The goal of restoring or creating wetlands on agricultural lands is almost always to remove nutrients and improve water quality. But new research shows that constructed marshes also excel at pulling carbon dioxide from the air and holding it long-term in soil, suggesting that farmers and landowners may also want to build wetlands to "farm" carbon.
Scientists led by a UCSF neurology researcher are reporting that they have identified the likely genetic mechanism that causes some patients with multiple sclerosis (MS) to quickly progress to a debilitating stage of the disease while other patients progress much more slowly.
Two new Baylor University studies show that Israeli Jewish adults who attend synagogue regularly, pray often, and consider themselves religious are significantly healthier and happier than their non-religious counterparts. They also report greater satisfaction with life.

Forsyth, M.D., of Moffitt’s Neuro-Oncology Program, says the combination has been shown to infect and kill both brain cancer stem cells and differentiated compartments of glioblastoma multiforme.
An investigative team of infectious disease experts who traveled to Saudi Arabia during an outbreak of the Middle East respiratory syndrome coronavirus reports that the virus poses a serious risk to hospitals because it is easily transmitted in health care settings.
Although as many as 25 percent of patients undergoing surgery suffer from sleep apnea, few hospitals have policies to help manage the risks of this condition during surgery, and there is little evidence to help guide anesthesiologists and surgeons caring for these patients.
Some parents desire for their children to fulfill their own unrealized ambitions, just as psychologists have long theorized, according to a new first-of-its-kind study.
One in four people who survive a stroke or transient ischemic attack (TIA) suffer from symptoms of PTSD within the 1st year post-event, and one in nine experience chronic PTSD more than a year later. The data, e-published by PLOS ONE, suggest that each year nearly 300,000 stroke/TIA survivors will develop PTSD symptoms as a result of their health scare.
In what is believed to be the largest follow-up record of patients with the most common form of hereditary dystonia – a movement disorder that can cause crippling muscle contractions – experts in deep brain stimulation report good success rates and lasting benefits. The findings will be published in the July issue of the journal Neurosurgery (available online now).

The cover story in the June issue of Genetics describes a new technique allowing scientists to study the function of individual proteins in individual cell types in a living organism, providing deeper insights into protein function by isolating its function. Until now there was no tool for this.
The role of dietary fructose in the development of obesity and fatty liver diseases remains controversial, with previous studies indicating that the problems resulted from fructose and a diet too high in calories. However, a new study conducted in an animal model at Wake Forest Baptist Medical Center showed that fructose rapidly caused liver damage even without weight gain. The researchers found that over the six-week study period liver damage more than doubled in the animals fed a high-fructose diet as compared to those in the control group.
In a study published in the June 19 online edition of the journal Nature, a scientific team led by researchers from the University of California, San Diego School of Medicine visually monitored the dynamic cellular events that take place when cardiac regeneration occurs in zebrafish after cardiac ventricular injury.
