While many Americans will be relaxing after their Thanksgiving Day feast, many people around the world may have a shortage of food, particularly potatoes, a staple that is being seriously threatened by a disease called potato late blight.

In a news story appearing in the journal Science (Nov. 29), “Taking the Bite Out of Blight,” writer Glenn Garelik examines the disease that is affecting potato production globally.

Potato late blight (Phytophthora infestans ) is the pathogen tha

Study opens door for faster, simpler methods of measuring carbon nanotubes

Building upon this summer’s groundbreaking finding that carbon nanotubes are fluorescent, chemists at Rice University have precisely identified the optical signatures of 33 “species” of nanotubes, establishing a new methodology for assaying nanotubes that is simpler and faster than existing methods.

A new study, just published in the journal Science, shows for the first time that some bacteria that cause diseases in humans use molecular hydrogen as an energy source. The research could point the way toward new treatment regimens for everything from ulcers and chronic gastritis to stomach cancer.

Microbiologists at the University of Georgia worked specifically in mice with the gastric bacterium Helicobacter pylori, a pathogen that colonizes the mucosal surfaces of the human stomach and g

An accepted assumption in astrophysics holds that it takes more than 1 million years for gas giant planets such as Jupiter and Saturn to form from the cosmic debris circling a young star. But new research suggests such planets form in a dramatically shorter period, as little as a few hundred years.

The forming planets have to be able to survive the effects of nearby stars burning brightly, heating and dispersing the gases that accumulate around the giant planets. If the process takes too lo

VLT Interferometer Measures the Size of Proxima Centauri and Other Nearby Stars [1] At a distance of only 4.2 light-years, Proxima Centauri is the nearest star to the Sun currently known [2]. It is visible as an 11-magnitude object in the southern constellation of Centaurus and is the faintest member of a triple system, together with Alpha Centauri, the brightest (double) star in this constellation. Proxima Centauri is a very-low-mass star, in fact barely massive enough to bu

Thanks to the cochlear implant deaf children under two years old can express and understand properly the language. Those are the results obtained by the University Clinic of the University of Navarre.

The University Clinic of Navarre is a pioneer in cochlear implant. This technique replaces the ear with a system that stimulates the hearing nerve electrically.

The programme of cochlear implant started in 1989 and one year later was done the first implant. This first implant was mad
