Chemical analyses of ancient organics absorbed, and preserved, in pottery jars from the Neolithic village of Jiahu, in Henan province, Northern China, have revealed that a mixed fermented beverage of rice, honey, and fruit was being produced as early as 9,000 years ago, approximately the same time that barley beer and grape wine were beginning to be made in the Middle East.

In addition, liquids more than 3,000 years old, remarkably preserved inside tightly lidded bronze vessels,

There is undeniable proof that water once existed on the planet Mars, a team of researchers has concluded in a series of 11 articles this week in a special issue of the journal Science.

A team of more than 100 scientists from numerous government agencies and universities, among them Mark Lemmon of Texas A&M University’s College of Geosciences, co-wrote the articles. Lemmon was the principal author on one article and co-author on three others describing the work of Spiri

Drawing on experiments with blue jays, a team of University of Minnesota researchers has found what may be the evolutionary basis for impulsive behavior. Such behavior may have evolved because in the wild, snatching up small rewards like food morsels rather than waiting for something bigger and better to come along can lead to getting more rewards in the long run. The work may help explain why many modern-day humans find it so hard to turn down an immediate reward–for example, food, money, sex o

In a world where 842 million people suffer from chronic hunger, insect pests consume 20-30 percent of world food crops. Chemical pesticides are increasingly expensive, ineffective and environmentally aggressive, killing beneficial insects and, when transmitted through the food chain, moving in unwanted directions.

The search for eco-friendly bio-insecticides has focused mainly on developing transgenic crops that express natural protein toxins. The most successful, by far, are crops

An antimicrobial agent found in many shampoos and hand lotions and widely used in industrial settings inhibits the development of particular neuron structures that are essential for transmitting signals between cells, according to a University of Pittsburgh study presented today at Cell Biology 2004, the 44th annual meeting of the American Society for Cell Biology. The meeting is being held Dec. 4 – 8 at the Washington Convention Center.

While millions of people across the world enjoyed the tale of a father fish in search of his lost son in the film Finding Nemo, a research project at the University of Leicester has delved into the reality of how fish find and recognise one another.

In a case of life imitating art, the scientists at Leicester have discovered that there are techniques that ’friendly fish’ use to find one another.
