A new raptorial dinosaur fossil with exceptionally long feathers, including a long feathered tail, has led the authors to believe they were instrumental for decreasing descent speed and assuring safe landings. 

Changyuraptor yangi is a 125-million-year-old dinosaur found in the Liaoning Province of northeastern China. The location has seen a surge of discoveries in feathered dinosaurs over the last decade. The newly discovered, remarkably preserved dinosaur sports a full set of feathers cloaking its entire body, including the extra-long tail feathers.

A new research paper analyzed how cooperative attitudes evolve in different age ranges. 

A new paper has found that drug paraphernalia triggers the reward areas of the brain differently in dependent and non-dependent marijuana users.

The 2012 National Survey on Drug Use and Health shows marijuana is the most widely used illicit drug in the United States. According to a 2013 survey from the Pew Research Center, 48 percent of Americans ages 18 and older have tried marijuana. The National Institute on Drug Abuse states that 9 percent of daily users will become dependent on marijuana.

The Magnetometer instrument that will fly on NOAA's GOES-R satellite when it is launched in early 2016 has completed the development and testing phase and is ready to be integrated with the spacecraft. 
The GOES-R series will be more advanced than the current GOES fleet. The satellites are expected to more than double the clarity of today's GOES imagery and provide more atmospheric observations than current capabilities with more frequent images.

The University of Manchester's National Confidential Inquiry into Suicide and Homicide by People with Mental Illness found that mental health patients are at their highest risk of suicide in the first two weeks after leaving hospital.

Around 3,225 patients died by suicide in the UK within the first three months of their discharge from hospital – 18% of all patient suicides between 2002-2012 - and 526 patients died within the first week, the peak time of risk in England, Northern Ireland and Scotland. In Wales, it is the first two weeks after leaving the hospital.  

What creates the two gigantic donuts of radiation surrounding Earth called the Van Allen radiation belts? The Van Allen Probes launched in 2012 want to find out.

The inner Van Allen radiation belt is fairly stable, but the outer one changes shape, size and composition in ways that scientists don't yet perfectly understand. Some of the particles within this belt zoom along at close to light speed, but just what accelerates these particles up to such velocities? Recent data from the Van Allen Probes suggests that it is a two-fold process: One mechanism gives the particles an initial boost and then a kind of electromagnetic wave called Whistlers does the final job to kick them up to such intense speeds.
