Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

...tly rises 1,000 meters -- more than half a mile -- above a bedrock plateau. Some computer reconstructions indicate it was perhaps twice as thick at the end of the last ice age, also called the Last Glacial Maximum. But evidence from an ice core extracted near Siple Dome from 1997-99, along with other calc...

New lab technique identifies high levels of pathogens in therapy pool

...many of them pathogenic, were enriched just inches above the pool's surface by as much as 60 percent. The microbes included "Mycobacterium avium," which can cause "lifeguard lung" and which was present in nine ill lifeguards who worked at the facility. The technique used in the study is 1,000 times more ...

Nanoparticles offer new hope for detection and treatment

...cles are a few thousand times smaller than the dot above this "i," yet each can carry about 100,000 molecules of the metal used to provide contrast in MRI images. This creates a high density of contrast agent, and when the particles bind to a specific area, that site glows brightly in MRI scans. In this s...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...s and not hearing them, microphones were installed above ground so researchers could monitor all low frequency sounds in the air. "The results of our 2002 study showed us that elephants do indeed detect warning calls played through the ground," O'Connell-Rodwell observes. "We expected them to clump up into...

Discovery clarifies role of peptide in biological clock

... that can be found on the bottom of the brain just above the roof of your mouth where your optic nerves cross. There are roughly 10,000 neurons in this nucleus on either side of your brain. The timekeeping mechanism in these cells depends on daily cycles in gene activity. Herzog found in his latest study ...

Bobbing birds do it for a reason

... North America--their eyes can be more than 5 feet above the ground--whooping cranes exhibit high-amplitude head movements during locomotion, making the measurement of the speed of the head relatively easy via non-invasive computer-video techniques.
