Alcohol is unlikely to protect drinkers from the risk of developing adult onset (type II) diabetes, concludes research in the Journal of Epidemiology and Community Health. Alcohol seems to confer only a slight advantage in moderate drinkers, the research shows.

To date, the effects of light to moderate alcohol consumption on the risk of developing adult onset diabetes remain unclear.

The researchers monitored over 5000 men between the ages of 40 and 59 for almost 17 years. None of t

Researchers have discovered a possible added benefit of hormone replacement therapy: saving teeth.

Postmenopausal women who took a daily dose of estrogen along with calcium, vitamin D and regular dental check-ups improved the condition of their jaw, which could potentially reduce the risk of tooth loss. Women who had regular check-ups but took only calcium and vitamin D also improved jaw mass and density, though to a significantly lesser extent than those who received estrogen.

Scientists from the University of Cambridge’s Astrophysics Group have today (21 June 2002) announced a collaboration with teams based in New Mexico, Puerto Rico and at the Naval Research Laboratory in Washington DC to design, install and operate a novel type of astronomical telescope for ultra-high angular resolution observations of stars, galaxies and quasars.

The agreement between researchers based in the Astrophysics (AP) Group at the Cavendish Laboratory and the Magdalena Ridge Observato

Taking their cue from fish, scientists in the US have built a navigational aid that will help robots and remote sensors find their way around the world`s vast oceans. The team describes its research today in the Institute of Physics publication Journal of Micromechanics and Microengineering.

Fish and many amphibian animals find their way through even the murkiest of waters, navigate raging torrents and spot obstacles, predators and prey using a sensory organ known as the lateral line system.

According to fellow phycologists, algae expert Stefan Draisma from the Leiden University has turned brown algae phylogeny completely upside down. His research shows that few of the currently assumed relationships between the orders are correct. Furthermore, it transpires that some simple species arose not earlier but later than more complex species.

Brown algae are multicellular algae. Brown pigments mask the green colour of the chlorophyll. Most of the species occur in temperate regions. Th

At the Hubrecht Laboratory in Utrecht, the biologist Sylvia Fischer has discovered how organisms protect themselves against transposons. Transposons are pieces of DNA which can translocate themselves within the genome. Sometimes transposons cause damage to the DNA. Plants probably have a similar mechanism which protects them against viruses.

Biologists from Utrecht discovered that the nematode C. elegans keeps transposons in check with a sophisticated mechanism. Due to the mechanism, the tra
