Scientists have discovered that induction of a gene known as MDA-7/IL-24 is the molecular mechanism that enables nonsteroidal anti-inflammatory drugs (NSAIDs) to halt the growth of cancer cells, a finding that could eventually lead to the development of targeted cancer treatments.
USC computer scientists have found a cheap, quick and copyright-respecting way to turn existing print brain atlases into multimedia resources. The software, now available in an experimental beta version for free download, is a robust and user-friendly interface that works on all the most popular computer operating systems.
Findings of Kent State University scientists indicate that manipulating the size of colloids, micron-sized or nanometer-sized particles, can produce huge changes in the material properties of liquid crystals.
Scientists at the Scripps Research Institute, the University of Wisconsin School of Medicine and Public Health, and the Howard Hughes Medical Institute have revealed in atomic detail how the toxins that cause botulism target and bind to nerve cells. This new understanding could ultimately lead to new ways for treating botulism, as well as to improved therapies for nervous system diseases such as dystonias, cerebral palsy and multiple sclerosis.
The International AIDS Vaccine Initiative (IAVI) issued this statement today following a National Institutes of Health (NIH) decision to end two clinical trials of adult male circumcision in Uganda and Kenya. The NIH’s Data Safety and Monitoring Board (DSMB), reviewing interim data, found that medically performed circumcision significantly protected men in the trial from HIV infection.
Researchers have discovered a subtle new difference between men and women — this one occurring in the realm of eating.
Developed countries’ motivation to invest in greenhouse gas emission-reduction projects in developing countries is based on their desire to reduce air pollution they receive from abroad and keep transaction costs down, rather than to achieve global-scale pollution reductions. This analysis1 by Nives Dolsak and Maureen Dunn, from the University of Washington-Bothell, in the US, has been published in Springer’s journal Policy Sciences.
Research led by the National Drug Evidence Centre at the University of Manchester has found that drug misuse seems to have passed its peak in some previous problem areas.
Penn State researchers have developed an automated system that can determine which “J. Smith” is authoring papers on computer science — the one who teaches at Penn State or the one who teaches at M.I.T — as well as whether “J. Smith” is John Smith, Jane Smith, Joanna L. Smith or James H. Smith.
According to recent research, the complexity of tooth surfaces reveals the diet of a species. Scientists at the University of Helsinki’s Institute of Biotechnology and Department of Geology showed that the more complex the surface of an animal’s teeth, the greater the share of vegetables in its diet. For instance, the teeth of carnivores and rodents differ in almost every aspect, but if a carnivore and a rodent eat similar food, their teeth are equally complex. The results were published in Nature.
