In a study that included nearly 60,000 patients with acute ischemic stroke, thrombolytic treatment (to help dissolve a blood clot) that was started more rapidly after symptom onset was associated with reduced in-hospital mortality and intracranial hemorrhage and higher rates of independent walking ability at discharge and discharge to home, according to a study in the June 19 issue of JAMA.

Male on male consensual sex and sexual assault common in South Africa
A survey of adult South African men published in this week's PLOS Medicine, shows that while overlapping sexual relationships with women appear to be common, roughly one in 20 men reported consensual sexual contact with a man, approximately one in ten reported being sexually assaulted by another man, and around 3 percent reported perpetrating such an assault.

New language discovery reveals linguistic insights
A new language has been discovered in a remote Indigenous community in northern Australia that is generated from a unique combination of elements from other languages. Light Warlpiri has been documented by University of Michigan linguist Carmel O'Shannessy, in a study on "The role of multiple sources in the formation of an innovative auxiliary category in Light Warlpiri, a new Australian mixed language," to be published in the June, 2013 issue of the scholarly journal Language.

Can new FDA graphic warning labels for tobacco pass a first amendment legal challenge?
When the FDA imposes new graphic warning labels for tobacco products, they can survive a First Amendment challenge if they depict health consequences and their effectiveness is supported by adequate scientific evidence, says a Georgetown public health expert/attorney. In an analysis of legal and scientific issues for graphic warning labels, John Kraemer outlines how the courts will likely analyze graphic warnings and identifies what health evidence must be presented to survive a legal challenge.

Atherosclerosis in abdominal aorta may signal future heart attack, stroke
In a study of more than 2,000 adults, researchers found that two MRI measurements of the abdominal aorta -- the amount of plaque in the vessel and the thickness of its wall -- are associated with future cardiovascular events, such as a heart attack or stroke.

Smoking and neurosurgical outcomes
Researchers found strong evidence for the association between active smoking and perioperative complications throughout the surgical literature. On the basis of their findings -- higher rates of intraoperative blood loss, greater need for intraoperative transfusions, higher rates of postoperative complications, and, in some patients with cranial cancer, shorter survival times -- the researchers conclude that there are strong reasons for neurosurgeons to urge their patients to quit smoking prior to surgery.

Fibromyalgia is not all in your head, new research confirms
Integrated Tissue Dynamics has discovered the first physically-detectable pathology associated with fibromyalgia, an enigmatic disease often viewed as more mental than physical. The research, published in Pain Medicine, revealed that female fibromyalgia patients have an excessive sensory nerve supply to small valves (shunts) among blood vessels deep in the palmar skin. This discovery provides a first logical rationale for fibromyalgia symptoms of extreme tenderness in the hands as well as widespread muscular aching and fatigue.

Aspirin may fight cancer by slowing DNA damage
Aspirin is known to lower risk for some cancers, and a new study led by a UC San Francisco scientist points to a possible explanation, with the discovery that aspirin slows the accumulation of DNA mutations in abnormal cells in at least one pre-cancerous condition.

Working backward: Computer-aided design of zeolite templates
Taking a page from computer-aided drug designers, Rice University researchers have developed a computational method that chemists can use to tailor the properties of zeolites, one of the world's most-used industrial minerals. The method allows chemists to work backward by first considering the type of zeolite they wish to make and then creating the organic template needed to produce it. The research appears this week in the Journal of Materials Chemistry A.

UT Arlington provides first academic study of journalists and private citizens' drone use
Newly published research from a University of Texas at Arlington communication team offers a groundbreaking perspective on the controversial use of unmanned aerial vehicles in journalism and mass communication, or "drone journalism." Researchers analyzed the first eight documented cases of drones being used in journalism. They found that there are significant issues that the Federal Aviation Administration will need to address or, they predict, legislative bodies will have to get involved.

Second Atlantic season tropical depression forms
Tropical Depression 2 formed in the western Caribbean Sea during the early afternoon hours on June 17. NOAA's GOES-13 satellite captured an image of the storm as it consolidated enough to become a tropical depression while approaching the coast of Belize. NOAA's GOES-13 satellite sits in a fixed orbit and monitors the weather in the eastern half of the continental United States and the Atlantic Ocean.

Pyrocumulus cloud billows from New Mexico fire
On June 12, 2013, the Moderate Resolution Imaging Spectroradiometer on NASA's Aqua satellite captured this image of the Silver fire burning east of Silver City, N.M. In addition to producing gray smoke plumes, the fire spawned a pyrocumulus cloud -- a tall, cauliflower-shaped cloud that billowed up above the smoke.
