Novel mouse gene reduces major pathologies associated with Alzheimer's disease
A new study reveals that a previously undiscovered mouse gene reduces the two major pathological perturbations commonly associated with Alzheimer's disease (AD). The research, published by Cell Press in the Nov. 12 issue of the journal Neuron, finds that the novel gene interacts with a key cellular enzyme previously linked with AD pathology, thereby uncovering a new strategy for treating this devastating disorder.

The sequence of maize line B73
The genome of the B73 inbred maize line, which has been sequenced by Patrick Schnable and colleagues, should help answer a number of long-standing questions, including the impact of mobile DNA sequences called transposable elements and how the modern maize genome evolved after two ancestral genomes fused together, researchers report in the Nov. 20 issue of Science.

Prevalence of high LDL, or 'bad' cholesterol levels decreases in US
Between 1999 and 2006, the prevalence of adults in the US with high levels of LDL cholesterol, the "bad" cholesterol, decreased by about one-third, according to a study in the November 18 issue of JAMA. But a high percentage of adults still are not being screened or treated for high cholesterol levels.

Middle Pleistocene mammalian fauna of Shanyangzhai cave in Qinhuangdao area, China
The formation and evolution of the Chinese zoogeographical regions has received much attention and has been widely debated in the academic community. In the edition of Chinese Science Bulletin, paleontologist from Northwest University have published new paleozoology details to suggest that the three zoogeographical faunas of Northeast, North and Mengxin, may have begun to appear during the Middle Pleistocene at the Chinese Palaearctic realm.

Clues to Fanconi Anemia
The Nov. 12 issue of Science reports that new research reveals some of the molecular underpinnings of Fanconi anemia, a rare genetic disease that leads to bone-marrow failure, developmental abnormalities and an increased risk of cancer. Scientists have already identified 13 genes that, when mutated, cause the disease, but the genes' precise role has not been clear.

Findings suggest lipid assessment in vascular disease can be simplified, without the need to fast
Lipid assessment in vascular disease can be simplified by measuring either total and HDL cholesterol levels or apolipoproteins, without the need to fast and without regard to triglyceride levels, according to a study in the November 11 issue of JAMA.

Fingerprint technology beats world's toughest tests ... including 100s of builders' thumbs
Technology developed by the University of Warwick that can identify partial, distorted, scratched, smudged, or otherwise warped fingerprints in just a few seconds has just scored top marks in the world's two toughest technical fingerprint tests. The technology is also being rapidly taken up by the UK building trade who are delighted to have fingerprint technology which can cope with the often worn and ravaged builders' thumbprints.
