Research Finds New Channels to Trigger Mobile Malware

2 days ago

Researchers at the University of Alabama at Birmingham (UAB) have uncovered new hard-to-detect methods that criminals may use to trigger mobile device malware that could eventually lead to targeted attacks launched by a large number of infected mobile devices in the same geographical area. Such attacks could be triggered by [...]

Helping Kids With Severe Respiratory Failure Survive Until Lung Transplantation

Adults with end-stage respiratory failure and pulmonary hypertension requiring ECMO (extracorporeal membrane oxygenation) have been “bridged” toward lung transplantation with novel lung assist devices such as the Novalung. This and related devices work based on pumpless application of oxygenators. A presentation by David M. Hoganson, MD, and colleagues from Washington [...]

Some ‘Green’ Hot Water Systems Fail to Deliver on Promises

Two researchers affiliated with the Virginia Tech College of Engineering have published a paper which reports that hot water recirculating systems touted as “green,” actually use both more energy and water than their standard counterparts. Marc Edwards, the Charles P. Lunsford Professor of Civil and Environmental Engineering in the Virginia [...]

Hubble Captures Comet ISON

Comet ISON is potentially the "comet of the century" because around the time the comet makes its closest approach to the Sun, on November 28, it may briefly become brighter than the full Moon. Right now the comet is far below naked-eye visibility, and so Hubble was used to snap the view of the approaching comet, which is presently hurtling toward the Sun at approximately 47,000 miles per hour. When the Hubble picture was taken on April 10, the comet was slightly closer than Jupiter's orbit at a distance of 386 million miles from the Sun. Even at that great distance the Sun is warming the comet enough to trigger outgassing from its frozen gases locked up in the solid nucleus. Hubble photographed a jet blasting dust particles off the sunward-facing side of the comet's nucleus. Preliminary measurements from the Hubble images suggest that the nucleus of ISON is no larger than three or four miles across. The comet was discovered in September 2012 by the Russian-led International Scientific Optical Network (ISON) using a 16-inch telescope.

This NASA Hubble Space Telescope image of Comet C/2012 S1 (ISON) was photographed on April 10, when the comet was slightly closer than Jupiter’s orbit at a distance of 386 million miles from the Sun (394 million miles from Earth). Even at that great distance the comet is already active [...]
