An abdominal aortic aneurysm is a potentially life-threatening condition: If the body's major blood vessel ruptures, it can prove deadly.

Abdominal aortic aneurysms are a bulge in the aorta, which is the body's largest artery and is located in the abdomen above the belly button. The greatest risk is that the aneurysm will rupture.
That's scary but who should be watched?

The U.S. Preventive Services Task Force recently updated its recommendations on screening and Mayo Clinic vascular surgeon Peter Gloviczki, M.D., outlines how people are diagnosed and how surgery, which now includes a less invasive endovascular option, is improving survival rates

The 2010 BP Deepwater Horizon spill in the Gulf of Mexico was, to-date, the largest accidental release of oil into the ocean. 210 million gallons issued from the blown-out well.

In an attempt to prevent vast quantities of oil from fouling beaches and marshes, BP applied 1.84 million gallons of the dispersant compound DOSS to oil released in the subsurface and to oil slicks at the sea surface. DOSS rapidly degrades in the environment but a new study by scientists at Haverford College and Woods Hole Oceanographic Institution (WHOI) found that though DOSS does decrease the size of oil droplets and hampers the formation of large oil slicks, it can persist in the environment for up to four years.

Cases of the highly contagious drug-resistant bacteria carbapenem-resistant Enterobacteriaceae  (CRE), have increased fivefold in community hospitals in the Southeastern United States, according to a new study in Infection Control and Hospital Epidemiology.

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.

Rainwater can penetrate below the Earth's fractured upper crust, according to a new study.

It had been thought that surface water could not penetrate the ductile crust, where temperatures of more than 300°C and high pressures cause rocks to flex and flow rather than fracture, but researchers have now found fluids derived from rainwater at these levels. 

Fluids in the Earth's crust can weaken rocks and may help to initiate earthquakes along locked fault lines. They also concentrate valuable metals such as gold. The new findings suggest that rainwater may be responsible for controlling these important processes, even deep in the Earth.
