Scientists from Johns Hopkins and the University of Wisconsin have discovered that a protein called Sir2, which is found in nearly all living cells, has a new function that might help explain how calorie restriction can increase lifespans for some animals, the scientists say. Their report appeared in the Dec. 20 issue of Science.

A number of laboratories have shown that restricting total calorie intake extends the lifespans of organisms ranging from yeast to laboratory animals. Others have

The biological clock – timekeeper for virtually every activity within living things, from sleep patterns to respiration – is a single protein, Purdue University researchers report.

The husband and wife team of D. James and Dorothy Morré has discovered this protein, which is responsible for setting the length of periods of activity and inactivity within cells. If the protein is altered, an organism’s body will experience “days” of different length – ranging from 22 to 42 hours in

Scientists at Long Ashton Research Station have identified a gene with a pivotal role in regulating seed germination. According to an article published in the January issue of BBSRC business, the Arabidopsis COMATOSE (CTS) gene, is vital for breaking seed dormancy. It is also analogous to the human X-ALD gene, which featured in the 1992 film “Lorenzo’s oil”. Treatment of cts mutants with a plant version of Lorenzo’s oil cures their inability to germinate.

The University of the Basque Country, IBERDROLA (an electricity utility supplying the Basque Country), the enterprises INGETEAM and INDAR and innovative energies company EHN have participated jointly in this research project. The project has put forward an innovative use of wind-sourced energy to control fluctuations on the grid. The research site where measurements were made was the Salajones wind park in Sanguesa (Navarre).

In recent years the electricity utilities have shown much greater

An Australian scientist has made a discovery which is electrifying world fungal biology – a new truffle genus related to the famous Amanita family, or fairy toadstools.

The Amanita family is famed worldwide for the red and white-spotted toadstools beloved of children’s fairy tales, the lethal Death Cap beloved of tabloid media, and a range of delicious edible fungi beloved of gourmets.

The find, by CSIRO Forestry and Forest Products mycologist Dr Neale Bougher, highli

Technique could help bring efficiency of biology to man-made materials

A Princeton chemist has developed a general mathematical system for designing materials that perform two functions at once, even when the desired properties sometimes conflict with each other.

Salvatore Torquato and colleagues used computers to calculate the optimum structure for any material that is a composite of two substances with differing properties. The achievement is the first simple example of a
