Leishmaniases and trypanosomiases are parasitic diseases which kill several thousands of people per year, mainly in developing countries. The effectiveness of existing treatments is being called into question owing to their toxicity and the emergence of resistance. A family of alkaloids, the quinolines, could be a worthwhile new therapeutic line to follow. Following on from the discovery of anti-leishmaniasis activity in natural quinolines, a research team of IRD, Pasteur Institute and CNRS sci

An analysis of previously uncharted chemical contents, mostly carbohydrates, in U.S.-consumed mushrooms shows that these fruity edible bodies of fungi could be tailored into dietary plans to help fill various nutritional needs.

Using modern analytic tools, scientists at the University of Illinois at Urbana-Champaign found that the six mushroom varieties tested – in raw and cooked forms and at various harvest times and maturity levels – are rich in total dietary fibers, including

A Howard Hughes Medical Institute (HHMI) professor and 138 of his undergraduates have co-authored a paper that provides the first genome-wide estimate of vital genes that are also essential for eye development of the common fruit fly, Drosophila melanogaster. The undergraduates are students in a unique biology class taught by HHMI professor Utpal Banerjee at the University of California, Los Angeles.

Banerjee and his students identified 501 essential genes responsible for proces

A new semantic web interface, which will improve access to information and present search results in associated categories in one window, was launched this week.

This new approach means that instead of users having to wade through long lists of search data to decide what is relevant, the interface will enable the machine to pull related sources into one usable view.

The new mSpace software framework developed by the School of Electronics & Computer Science (ECS) at t

Take a moment and look at a picture near you. What did you see? How long did it take you to understand what was in the image, meaning how long did it take you to realize the green blob was a tree? Or that the orange circle was a piece of fruit? Most likely you assume that it took you no time at all, you just knew.

Psychologists who study how we perceive images used to think that, before the process of object recognition and categorization could begin, the brain must first separate

Researchers at The University of Texas M. D. Anderson Cancer Center have discovered a cluster of 12 genes on the X chromosome in mice that appears to play an important role in reproduction. Reporting in the journal Cell, the scientists showed that knocking out just one of the genes resulted in reduced fertility in male mice.

The researchers found the cluster, which they dubbed the reproductive homeobox X-linked (or Rhox) genes, is selectively expressed in male and female reprod
