DNA downloads alone

The information in DNA can be copied into new molecules without proteins’ help.

Chemists have reproduced the basic process of information transfer central to all life without the catalysts that facilitate it in living cells 1 .

They show that DNA alone can pass its message on to subsequent generations. Many researchers believe that DNA-like molecules acted thus to get life started about four billion years ago – before catalytic proteins existed to help DNA t

Collaboration on the discovery and the development of new drug targets and candidates for CNS diseases

GENOPIA Biomedical LLC (GENOPIA), a biotechnology firm headquartered in Saarbücken, Germany and Ciphergen Biosystems, Inc. (Nasdaq: CIPH) in Fremont, CA, will collaborate on the discovery and the development of new drug targets and candidates for CNS diseases. GENOPIA Biomedical focuses on the development of novel drug candidates and uses advanced proteomics as its main drug discovery and high-throughput screening tool, while Ciphergen Biosystems is a world leader in the development of proteomics te

Water pollutants purged

Smart process cleans up contaminated water.

A smart material identifies and destroys toxic pollutants in water. When exposed to the offending molecules, tiny light-emitting zinc oxide particles glow dimly, burn them up, and glow brightly to show they’ve finished 1 .

The advantage of such an approach, say Prashant Kamat and co-workers at the University of Notre Dame in Indiana, is that the energy-consuming burn-up stage switches on only when pollutants are pre

Lifou 2000: A Major Scientific Survey

The coral reefs of New Caledonia, a major focus of marine biodiversity, are exceptional as subjects for investigation by zoologists and ecologists. They harbour an extraordinary profusion of species, representing one of the most complex ecosystems in the world’s oceans. Exploration of a single bay, during the Lifou 2000 research campaign, found a treasure trove of discoveries highly stimulating for scientific imagination and debate.

The scientific survey LIFOU 2000, organized and led jointly

Studies Raise Questions about Climate Change

Climate prediction just got trickier, according to two new studies appearing in the current issue of the journal Science. Analysis of more than two decades of satellite data shows that more sunlight entered the tropics and more heat escaped to space in the 1990s than a decade earlier. Moreover, current climate models fail to account for the new findings, suggesting that they may contain more uncertainty than previously thought.

For the earth’s climate to remain unchanged, the planet’s ener

Genes are of little importance in rheumatoid arthritis

Genes are of little importance in the development of rheumatoid arthritis, finds a study in this week’s BMJ.

Researchers in Denmark surveyed over 37,000 twins about rheumatic diseases. Twin studies are one of the simplest ways to unravel the relative importance of genetic and environmental effects of a disease. Twins who reported that they had rheumatoid arthritis were invited to have a clinical examination.

Rheumatoid arthritis was verified in 13 identical and 36 non-identic
