Less invasive procedure for repair of abdominal aortic aneurysm may reduce short-term risk of death
Patients who received the less-invasive endovascular repair of an abdominal aortic aneurysm had a lower risk of death in the first 30 days after the procedure compared to patients who an open repair, but both procedures had similar rates of death after two years, according to a study in the Oct. 14 issue of JAMA, a theme issue on surgical care.

Minimally invasive radical prostatectomy shows advantages, higher rates of certain complications
New research indicates that the use of minimally invasive procedures (including the use of robotic assistance) for radical prostatectomy, which have increased significantly in recent years, may shorten hospital stays and decrease respiratory and surgical complications, but may also result in an increased rate of certain complications, including incontinence and erectile dysfunction, according to a study in the Oct. 14 issue of JAMA, a theme issue on surgical care.

Dyslexia varies across language barriers
Chinese-speaking children with dyslexia have a disorder that is distinctly different, and perhaps more complicated and severe, than that of English speakers. Those differences can be seen in the brain and in the performance of Chinese children on visual and oral language tasks, reveals a report published online on Oct. 12 in Current Biology, a Cell Press publication.

Protoplanet 2 Pallas
Images from the Hubble Space Telescope suggest that the asteroid 2 Pallas is a protoplanet that has remained intact since its formation, in a study that puts 2 Pallas in company with two other large asteroids, Ceres and Vesta. With a diameter of 265 km, 2 Pallas is one of the largest bodies in the main asteroid belt. B.E. Schmidt and colleagues have characterized its surface and shape using images from the Hubble Space Telescope in the Oct. 9 issue of Science.

San Andreas affected by 2004 Sumatran quake
US seismologists have found evidence that the massive 2004 earthquake that triggered killer tsunamis throughout the Indian Ocean weakened at least a portion of California's famed San Andreas Fault. Researchers from Rice University, the Carnegie Institution of Washington and the University of California, Berkeley, published the findings this week in Nature. The study suggests the Earth's largest earthquakes can weaken the strength of fault zones worldwide and trigger periods of increased global seismic activity.

Surgical masks vs. N95 respirators for preventing influenza among health-care workers
Surgical masks appear to be no worse than, and nearly as effective as N95 respirators in preventing influenza in health care workers, according to a study released early online today by JAMA. The study was posted online ahead of print because of its public health implications. It will be published in the November 4 issue of JAMA.

Before 'Lucy,' there was 'Ardi': First major analysis of early hominid published in Science
In a special issue of Science, an international team of scientists has for the first time thoroughly described Ardipithecus ramidus, a hominid species that lived 4.4 million years ago in what is now Ethiopia. This collection of articles, which will appear in the journal's Oct. 2, 2009, issue, offers the first comprehensive, peer-reviewed description of the Ardipithecus fossils, which include a partial skeleton of a female, nicknamed "Ardi."

New way to monitor faults may help predict earthquakes
Scientists at the Carnegie Institution have found a way to monitor the strength of geologic faults deep in the Earth. This finding could prove to be a boon for earthquake prediction by pinpointing those faults that are likely to fail and produce earthquakes. Until now, scientists had no method for detecting changes in fault strength, which is not measurable at the Earth's surface.
