Alzheimer's study first to explain death of brain cells

...discovered that Alzheimer's patients have abnormal amounts of heme in their brains. In new research results, Atamna's team showed that amyloid-beta readily binds with heme to form a compound that can be flushed from cells. When there is insufficient heme or too much amyloid-beta, however, the amyloid-beta fo...

Exposure to volcanic mineral associated with increased mesothelioma incidence in Turkey

...ons of inhibitants are likely exposed to hazardous amounts of mineral fibers from the environment. Resources should therefore be directed to preventing these environmental exposures and additional study of the association between environmental exposure to nonasbestos fibers and the risk of cancer." ...

Georgia Tech accelerates drug discovery with new IBM supercomputing cluster

Heparin prepared synthetically could replace animal-derived drug

...at MIT first prepared a synthetic heparin, but, in amounts of less than 1 microgram, it was insufficient to treat humans, says Linhardt. One human dose of heparin is approximately 100 milligrams. Rensselaer and UNC-Chapel Hill researchers successfully synthesized hundreds of milligrams of heparin by develop...

...esult, the DNA can make the wrong protein or wrong amounts of protein, which affects how the cells grow. Some of these cells can grow to become cancer. "Essentially, if you get a heavy metal stuck on DNA, you can get a mutation," Stearns explained. Other heavy metals are known to bind to DNA, but Stearns a...

'Biobullets' fight harmful mussels

...ce ingested, the "biobullets" slowly release small amounts of potassium chloride, a salt that is poisonous to most freshwater mollusks. Unlike other methods used to eradicate zebra mussels, such as chlorine, "biobullets" pose little or no threat to other marine animals, the researchers say, because they rapi...

MIT researchers build tiny batteries with viruses

Ocean acidification threatens cold-water coral ecosystems

... (Bellevue, WA) and colleagues say that increasing amounts of atmospheric carbon dioxide (CO2), driven by the burning of fossil fuels, are dissolving into the oceans, causing them to become slightly more acidic. This change in seawater chemistry could harm deep-sea calcifying animals like corals. Cold-water...
