As utility companies search for ways to avoid blackouts, like the one that shut down the northeastern corner of the United States last summer, one idea comes from the University of Wisconsin-Madison.

Researchers from the College of Engineering have designed a system where a small network of local generators can reliably disconnect from the rest of the power supply, enabling locations where electricity is critical to stay in operation.

Most buildings receive their electrical power

Authors of a UK study in this week’s issue of THE LANCET propose a new approach for cervical cancer screening. Testing for the human papilloma virus (HPV)-the main cause of cervical cancer-could be the primary screening tool, with cytology reserved for women who test positive for HPV.

HPV testing (by genetic analysis) of cervical smears is known to be more sensitive than conventional cytology for detecting pre-malignant cervical cells called high-grade cervical intraepithelial neoplasia (CIN

Engineers at Ohio State University have overcome a major barrier in the manufacture of high quality light emitting devices and solar cell materials.

Steven Ringel, professor of electrical engineering, and his colleagues have created special hybrid materials that are virtually defect-free — an important first step for making ultra-efficient electronics in the future.

The same technology could also lead to faster, less expensive computer chips.

Researchers tracking the ebb and flow of cognitive function in the human brain have discovered surprising differences in the ability of younger and older adults to shut down a brain network normally active during periods of passive daydreaming. The differences, which are especially pronounced in people with dementia, may provide a clear and powerful new method for diagnosing individuals in the very early stages of Alzheimer’s disease.

“In young adults, there are parts of the brain that

ESA’s Mars Express probe is scheduled to arrive at Mars at Christmas : the Beagle 2 lander is expected to touch down on the surface of the Red Planet during the night of 24 to 25 December.

Launched on 2 June 2003 from Baikonur (Kazakhstan) on board a Russian Soyuz operated by Starsem, the European probe – built for ESA by a European team of industrial companies led by Astrium – carries seven scientific instruments that will perform a series of remote sensing experiments designed to shed

Using sophisticated computer algorithms running on standard desktop computers, researchers have designed and constructed a novel functional protein that is not found in nature. The achievement should enable researchers to explore larger questions about how proteins evolved and why nature “chose” certain protein folds over others.

The ability to specify and design artificial proteins also opens the way for researchers to engineer artificial protein enzymes for use as medicines or industrial c
