A team of scientists has discovered three molecules –– from a search of 58,000 compounds –– that appear to inhibit a key perpetrator of Alzheimer’s disease.

Each of the three molecules protects the protein called “tau,” which becomes hopelessly tangled in the brains of patients with Alzheimer’s. The finding is promising news for the development of drugs for the disease.

A mechanism that lets herpes simplex virus infect most cells — and 45 million Americans — is discovered

It’s one of the most common viruses in America, and one that causes the most guilt and shame. It can get inside almost any kind of human cell, reproduce in vast numbers, and linger for years in the body, causing everything from recurrent genital blisters to sores around the mouth. Its complications can kill, and it may increase susceptibility to many nerve and brain disor

Cuvier’s beaked whales (Ziphius cavirostris) are an unusual sighting in most parts of the World, but are seen regularly in the Bay of Biscay. On a recent crossing of the Bay, a pod of 8 Cuvier’s beaked whales were observed to be displaying very unusual behaviour.

Cuvier’s beaked whales are amongst the more unusual and rare cetacean sightings globally. Like many species of beaked whale, they are known to inhabit deep-water canyons and slope waters, which tend to be found far from

Immersive cave will allow audience to watch robots search for victims

As the July 7 bombings in London have so devastatingly illustrated, disaster relief is an arduous task, one that is carried out mainly by humans (and trained dogs), communicating face-to-face or by phones and walkie-talkies. Robots may provide limited support for search and rescue activities and are typically remotely operated by a separate team of humans, but such robots can be difficult to control.

The American Association for the Advancement of Science (AAAS) has expressed deep concern about a congressional demand for detailed documentation on the scientific work and professional history of three researchers whose studies suggest temperatures in the Northern Hemisphere are warmer than they have been for a thousand years.

In a July 13 letter to U.S. Rep. Joe Barton, chairman of the House Committee on Energy and Commerce, AAAS CEO Alan I. Leshner said the committee’s requests to

Millions of vehicles produced each year are transported by purpose-built car carrying ships that can be turned around quickly. Research funded by the Economic and Social Research Council confirms that as a consequence of technical, infrastructure and production changes in the industry, crew members have experienced a decline in work/life balance. Shore leave for many may amount to having time for a telephone call home at the port of destination only – before needing to set sail again.
