Antarctic ice shelf retreats happened before

...ct said, 'We know that rising air temperatures can break up ice shelves but there has been a suspicion for some time that the role of the ocean may have been underestimated. This is some of the first evidence that a shift in ocean currents can actually destroy ice shelves. In this case it's possible that a...

Inexpensive, mass-produced genes core of synthetic biology advances at UH

...ted us from doing this, but Dr. Gao’sresearch will break down that barrier.?This technology offers tremendous potential benefits, as syntheticgenes could allow for development and production of safer, less toxicproteins that are currently used in disease treatment. It also couldallow for production of larg...

Vampire bats keep out of trouble by running

... to pass Riskin and Hermanson's treadmill test and break into a running gait. With the introduction of large herds of livestock into their native environments of Central and South America, these bats don't need to hurry to catch the cattle from which they extract perhaps a tablespoon of blood at a time fo...

Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows

...fluorescently labeled peroxisomes (organelles that break down toxic substances) inside specially cultured fruit fly cells. This was the first time the imaging technique had been used inside a living cell. "Our measurements show that both dynein and kinesin carry the peroxisomes in a step-by-step fashion, ...

McGill researchers shed light on formation of carcinogen in food

...istry, shows how food-based amino acids and sugars break down when heated to produce furan. It also identifies other food components, such as vitamin C and polyunsaturated fatty acids, which may produce furan as an unwanted by-product of cooking, bottling or canning food products. "Furan and its derivativ...

Microbial fuel cell: High yield hydrogen source and wastewater cleaner

...electrolysis, the process that uses electricity to break water down into hydrogen and oxygen. Logan adds, "This new process demonstrates, for the first time, that there is real potential to capture hydrogen for fuel from renewable sources for clean transportation." ...

Nano-bumps could help repair clogged blood vessels

...it can become loose, and parts of it will actually break off and go down the bloodstream," Webster said. "Essentially, what we've been trying to do is find new materials that cause the endothelial cells to attach better to these stents without creating as much dangerous scar tissue." The researchers teste...

Insight into DNA's 'weakest links' may yield clues to cancer biology

Novel gene-silencing nanoparticles shown to inhibit Ewing's sarcoma

... that Ewing's sarcoma results when two chromosomes break and trade their genetic content in what's technically called a "translocation," activating the oncogene EWS-FLI1 which triggers the tumor growth characteristic for this cancer. In their experiment, siRNA was delivered to this growth-promoting region...

Pair of cancer genes found to drive both cell migration and division

...P3 even when PI3K is missing, but the major way to break it down is by using PTEN. So if PTEN isn't there to destroy PIP3 at the furrow, the halves can't pull apart," says Chris Janetopoulos, Ph.D., a research associate in Devreotes's lab and first author on the paper. The cells' problems were eliminated w...
