New gene uncovered for late-onset Alzheimer's

...Alzheimer's disease puzzle. This appears to be the fifth Alzheimer's disease gene, and there are likely to be other important genetic variants that need to be identified before the entire picture is complete." "Instead of scanning all the genes in the entire genome, we had an idea of what an Alzheimer's d...

Nearly unbreakable

...uccessively lower length scales, until less than a fifth of that strain unit is actually seen by the mineral phase. Essentially, from the atomic to the micrometer level, bone consists of rigid units joined together by a soft phase, where most of the deformation occurs. These composite structures form a sin...

Unraveling where chimp and human brains diverge

...individually, it would be similar to reading every fifth word in a paragraph you don't get to see how each word relates to the other. So instead we used a systems biology approach to study each gene within its context." The scientists identified networks of genes that correspond to specific brain reg...

Bones at the nanoscale

... successively lower length scales, and less than a fifth of the strain is actually noticed in the mineral phase. The soft structures form a single rigid unit at the next level and so on, enabling the tissue to sustain large strains. This is why the brittle apatite remains shielded from excessive loads and ...

They also found that about half of the samples had lost one copy of the KEAP1 gene--cells usually have two copies of each gene. Five of the six tumors with KEAP1 mutations had lost the other (functional) copy of KEAP1--geneticis...

Each year approximately 40,000 Americans are diagnosed with head and neck cancer, and about 11,000 patients will die. Many cancers have a dysfunction in the p53 pathway that regulates the cell cycle, helping to protect...

Writing in the fifth century BC, in chapter 5 of his classic text, Aphorisms, he stated: "Swellings and pains in the joints, ulceration, those of a gouty nature, and sprains, are generally improved by a copious affusion of cold water, which reduces the swelling, and remo...

New research points toward mechanism of age-onset toxicity of Alzheimer's protein
