Scientists develop new treatments for Alzheimer's disease

...cteristic of Alzheimer's disease. The clumps are formed from a small protein fragment called Amyloid-beta (A-beta) peptide released from its 'parent' protein - amyloid precursor protein (APP). This process requires the action of an enzyme called beta-secetase (BACE), which is critical in clipping up the ...

Poinar, one of the world's experts in the study of amber, also has used it to provide a vivid re-creation of an ancient forest in the book "The Amber Fores...

Carnegie Mellon uses new imaging technique to discover differences in brains of people with autism

...a process called myelination, in which a sheath is formed around the fibers that speeds nerve impulses. The movement of water is more dispersed if the structural integrity of the tissue is low -- i.e., if the fibers are less dense, less coherently organized, or less myelinated -- as it was with the particip...

Researchers add to understanding of how brain cells communicate

...s disease, and stroke, said Johnson. Memories are formed by strengthening the connections between brain cells, known as synapses. If you touch a hot stove, the pain signal from your hand and the visual signal from your eyes reach the brain at about the same time, forging a memory. Specifically, memory requ...

Stretching bone marrow stem cells pushes them towards becoming blood vessel

...embrane with microgrooves to resemble the patterns formed in blood vessels by collagen fibers. The microgrooves were aligned either perpendicular or parallel to the axis of strain, and some of the cells were stretched while others were not. The researchers also looked at the effects of stretching stem cell...

Diversity promotes cooperation among microbes

...tures called biofilms. P. fluorescens biofilms are formed when individual cells overproduce a polymer that sticks the cells together, allowing the colonization of liquid surfaces. While production of the polymer is metabolically costly to individual cells, the biofilm group benefits from the increased acces...

Asian Soybean Rust found in Virginia, but not a threat to current crop

...Rust became imminent, Virginia agriculture leaders formed the Soybean Rust Task Force. It created a plan that includes educational programs for Virginia Cooperative Extension agents, crop advisers, growers, and others to understand what the disease looks like and what action to take if it is found. It estab...

Genetic repair mechanism clears the way for sealing DNA breaks

Horolodectes means 'hourglass biter', in reference to the creature's peculiar hourglass-shaped pre-molars, the teeth between the canine and...

Biofuel cells without the bio cells

...eins, outer membrane c-type cytochrome A, or OmcA, formed a dense coating on the iron-rich mineral hematite. The metal in the mineral acts as an "acceptor," or dumping point, for thousands of trillions of electrons per square centimeter shuttled by the OmcA-donor. The function is a relic of respiration, in ...
