As if the drivers of minivans and utility vehicles needed any more encouragement to drive fast between jobs, US researchers have designed a new rear spoiler for bluff-backed vehicles that can reduce drag and lift significantly.
Writing in the International Journal of Vehicle Design, the team describes how the new spoiler could improve fuel consumption as [...]

A previously unknown regulatory step during human immunodeficiency (HIV) replication provides a potentially valuable new target for HIV/AIDS therapy, report researchers at the Salk Institute for Biological Studies and the University of Wisconsin, Madison.
Their study, published in this week`s early online edition of the Public Library of Science, PLoS Pathogens, describes a new biological function [...]

The four drug-combination of carboplatin and paclitaxel, with the targeted therapies bevacizumab (Avastin) and cetuximab (Erbitux), is safe and may improve survival for patients with advanced lung cancer, according to a cooperative group study led by The University of Texas M. D. Anderson Cancer Center.
Presented today on the press program of the 2008 Chicago Multidisciplinary [...]

Researchers at the Moores Cancer Center at the University of California, San Diego (UCSD) are conducting clinical trials of a novel therapy aimed at revving up the immune system to combat a particularly difficult-to-treat form of leukemia.
The experimental therapy is being offered to patients with chronic lymphocytic leukemia (CLL) whose cancer did not respond or [...]

A Ph.D. student at Sydney`s Garvan Institute of Medical Research has uncovered an important piece in the puzzle of how insulin works, a problem that has plagued researchers for more than 50 years. The research brings scientists one step closer to explaining exactly how insulin prompts fat and muscle cells to absorb glucose.
The novel finding [...]

Neurodegenerative diseases, such as Alzheimer`s disease, Parkinson`s disease, and amyotrophic lateral sclerosis (ALS), disrupt the quality of life for patients, put a tremendous burden on family caregivers, and cost society billions of dollars annually.
The most consistent risk factor for developing neurodegenerative disease is aging. Because of the dramatic increase in life expectancy, the incidence of [...]

University of Delaware scientists, in collaboration with researchers from the University of Arizona and South Dakota State University, have identified unusual differences in the natural mechanisms that turn off, or “silence,” genes in corn.
The discovery, which was made by comparing the impact of inactivating a gene that occurs in both corn and in the much-studied [...]

Despite the rise of systems biology, many geneticists continue to probe genes in isolation. They even use cutting-edge RNA interference (RNAi) technology to knock down one gene at a time. This approach often yields a narrow view of cellular systems.
Now, researchers at Harvard Medical School, the Institute for Cancer Research, and the Institut de Biologia [...]

Colon cancer ranks second of all gastrointestinal malignant tumors, it is one of the leading causes of cancer-related deaths worldwide. Until now, several molecules have been reported to play an important role in gastroenterological tumorigenesis and tumor metastasis, but the molecular mechanisms involved tumor development and progression still remain unclear in colon cancer.
A research article [...]
