The protein MAEBL is critical for completing the life cycle of malaria parasites in mosquitoes, allowing the insects to transmit the potentially deadly infection to humans, a University of South Florida study has shown. The research may ultimately help provide a way to better control malaria by blocking development of the malaria parasite in the mosquito.

Scientists search for drug candidates in some very unlikely places. Not only do they churn out synthetic compounds in industrial-scale laboratories, but they also scour coral reefs and scrape tree bark in the hope of stumbling upon an unsuspecting molecule that just might turn into next year’s big block buster. But one region that scientists have not been searching is their guts. Literally.

A monkey has successfully fed itself with fluid, well-controlled movements of a human-like robotic arm by using only signals from its brain, researchers from the University of Pittsburgh School of Medicine report in the journal Nature. This significant advance could benefit development of prosthetics for people with spinal cord injuries and those with “locked-in” conditions such as Lou Gehrig’s disease, or amyotrophic lateral sclerosis.

An Iowa State University researcher has found that sick female deer mice devote their energy to producing healthier offspring.

A study released today reveals a cellular mechanism involved in alcohol dependence. The study, in the May 28 issue of The Journal of Neuroscience, shows that gabapentin, a drug used to treat chronic pain and epilepsy, reduces alcohol intake in alcohol-dependent rats by normalizing chemical communication between neurons, which is altered by chronic alcohol abuse.

You went to a wedding yesterday. The service was beautiful, the food and drink flowed and there was dancing all night. But people tell you that you are in hospital, that you have been in hospital for weeks, and that you didn’t go to a wedding yesterday at all.

Researchers at The University of Nottingham have taken some important first steps to creating a synthetic copycat of a living cell, a leading science journal reports.

Researchers from the John Innes Centre and the University of East Anglia have recently elucidated the structure and function of an enzyme which is involved in decorating antibiotics with sugar molecules. Many antibiotics have a variety of different carbohydrate molecules attached to them which can help the antibiotic to be taken up by the target organism or overcome resistance. By manipulating the sugar, it may be possible to restore usefulness in antibiotics to which resistance has developed.

Rocks made of basalt on and under the ocean bottom harbor surprising numbers of deep-sea bacteria. Seafloor bacteria on ocean-bottom rocks are more abundant and diverse than previously thought, appearing to "feed" on the planet's oceanic crust, according to results of a study reported in this week's issue of the journal Nature.
