Cyberbullying on Social Media Linked to Teen Depression Cyberbullying on social media is linked to depression in teenagers, according to new research that analyzed multiple studies of the online phenomenon. Victimization of young people online has received an increasing level of scrutiny, particularly after a series of high-profile suicides of teenagers who were reportedly bullied on various social networks. Social media use is hugely common among teenagers, said Michele Hamm, a researcher in pediatrics at the University of Alberta, but the health effects of cyberbullying on social media sites is largely unknown. Read More »Unhealthy Teens Face College and Job Obstacles Researchers found that teens with either mental health or chronic physical health conditions were less likely to graduate high school or finish college, and were more likely to be unemployed or have lower-income jobs as adults compared with healthy teens. The analysis also showed that teens with mental health problems fared worse than those with physical health issues in terms of economic and academic outcomes as young adults. "Mental health conditions may be more detrimental than physical health conditions, because they are linked with social isolation and exclusion, which are both linked with poor employment and education outcomes," said Daniel Hale, co-author of the study and a research associate in children's health policy at University College London.

When compared with an analysis conducted nearly 20 years before this study, the results show that more people are now overweight and obese, said Lin Yang, an epidemiologist at Washington University School of Medicine in St. Louis and a co-author of the study, published today (June 22) in the journal JAMA Internal Medicine. Yang said she sees the findings as a wake-up call to create policies designed to combat excessive weight gain and obesity, which burden the American health care system and society.

Flying for the fifth time, the four-stage Vega rocket, lifted off at 9:52 p.m. EDT (0152 GMT) carrying Europe's Sentinel-2A satellite, the newest member of the multibillion-euro Copernicus Earth-observation project. From its orbital perch 488 miles (786 km) above Earth, Sentinel-2A is designed to take high-resolution, color and infrared images for a wide array of environmental initiatives, including crop forecasting and monitoring natural disasters.

In addition, a Japanese businessman training as Brightman's backup signed a contract to fly to the orbital outpost when another Soyuz seat opens up in the next two- to four years, said Space Adventures, a U.S.-based travel agency that has brokered eight privately paid flights to the station. Last month, Brightman, 54, pulled out of training for a 10-day taxi flight, citing personal family reasons.

The team from the University of California, Berkeley based the robot on the humble cockroach and hope their design could be used to inspire future robot designs for use in monitoring the environment and search and rescue operations. The Berkeley team, led by postdoctoral researcher Chen Li, designed the shell so it could perform a roll maneuver to slip through gaps between grass-like vertical beam obstacles without the need for additional sensors or motors.

Algorithm Sorts Paintings Like a Person A team of researchers has developed an artificial intelligence (AI) program that can classify famous works of art based on their style, genre or artist — tasks that normally require a professional art historian. "We're definitely not replacing art historians, but with a growing number of paintings in online collections, we need an automatic tool" for organizing them, said study researcher Babak Saleh, a computer scientist at Rutgers University in New Brunswick, New Jersey. A human can look at a painting and easily draw inferences from it, such as whether it's a portrait or a landscape, whether the style is impressionist or abstract, or who the artist was.

"We believe it was the combination of squatting and tight jeans that caused the problem," said Dr. Thomas Kimber, of the Royal Adelaide Hospital and Department of Medicine in Adelaide, South Australia, who treated the woman. The case happened about six months ago, Kimber told Live Science.

However, there is not much evidence supporting the use of medical marijuana for other reasons, such as sleep disorders, Tourette syndrome and anxiety disorders. Still, many of the studies done to date that found that marijuana had little or no effect were small, or lacked a rigorous design, the researchers said.

Advancing China's space program has been set as a priority by leaders in Beijing, with President Xi Jinping calling for China to establish itself as a space power. China insists that its space program is for peaceful purposes.

Malloy have joined forces with U.S. firm SURVICE, 30 year veterans of defense research and development, to develop the vehicle in the U.S. state of Maryland. According to Malloy's marketing sales director Grant Stapleton, "there are a lot of advantages of the Hoverbike over a regular helicopter.

The effects of solitary confinement on a prisoner's well-being is a subject that has been debated since the first half of the 20th century, according to Peter Scharff Smith, a senior researcher at the Danish Institute for Human Rights in Copenhagen. While several studies have downplayed the negative effects of isolating prisoners for long periods of time, many more have concluded that this practice is quite harmful on both a physiological and psychological level, Scharff Smith told Live Science.

"Our findings highlight the need for continued surveillance among survivors of Ebola virus disease," the researchers, from Donka National Hospital in Guinea, wrote in the June 9 issue of the journal Clinical Infectious Diseases. Little is known about the long-term effects of Ebola, but such information is important for providing support for survivors of the current Ebola outbreak in West Africa, the researchers said.

Researchers looked at nine studies that assessed people's anxiety levels as well as their sedentary behavior, adding up how much time people spent doing activities like watching TV, working at a computer and playing video games. When examined together, the studies showed "moderate evidence" that increased sedentary behavior is associated with higher anxiety risk, the researchers wrote in the review, published online today (June 18) in the journal BMC Public Health.
