Memory loss associated with early Alzheimer's disease (AD) may be linked to altered activity in several areas of the brain, according to a study in the July issue of Radiology.

As the space shuttle Discovery prepares to launch on July 1, researchers at the University of Minnesota have identified a way for astronauts to reduce their risk of developing kidney stones while in space.

A revolutionary dissolvable scaffold for growing new areas of skin could provide a safer, more effective way of treating burns, diabetic ulcers and similar injuries.

A leaf-cutting ant queen (Acromyrmex coronatus) is sheltered in a chamber deep inside of her fungus garden, made of leaf fragments and strands of a symbiotic fungus.Fungus-farming ants around the world cultivate essentially the same fungus and are not as critical to the reproduction of the fungi as previously believed, biologists at The University of Texas at Austin have discovered.

Researchers have used a new technique to monitor brain development in infants and detect disturbances in white matter, according to a study in the July issue of Radiology.

Researchers continue to search for genetic clues into rheumatoid arthritis (RA), a chronic inflammatory joint disease. While its specific cause is not yet known, RA has been linked to an inherited susceptibility. Interestingly, despite its strong genetic component, RA's occurrence among siblings seems to be random.

Version 1.5 of the Integrated Microbial Genomes (IMG) data management system of the U.S. Department of Energy Joint Genome Institute (DOE JGI) has been released to the public. IMG 1.5 now contains a total of 741 genomes (435 bacterial, 32 archaeal, 15 eukaryotic genomes and 259 bacterial phages) of which 602 are finished and 139 are draft genomes.

Health physicists are establishing safe procedures for a promising experimental brain-cancer therapy which uses a radioactive version of a protein found in scorpion venom. For many, this will conjure images of Spiderman's nemesis, the Scorpion. The purpose of this work is not science fiction, but rather to help to develop a promising new therapy for brain cancer. The venom of the yellow Israeli scorpion preferentially attaches to the cells of a type of essentially incurable brain cancers known as gliomas.
