The genetic signal that makes a honeybee male or female has been identified by researchers in Germany, the U.S. and Norway. The finding, published in the August 22 issue of the journal Cell, shows how male bees can have no father, a scientific puzzle going back over 150 years and the explanation for why bees, ants and wasps often form colonial societies. It could also make it easier to breed honeybees.

The researchers found that female bees have two different versions of a gene called csd,

“My observations from a few years ago were that Ice Stream D in the West Antarctic was slowing to about half average speed and then speeding up,” says Dr. Sridhar Anandakrishnan, associate professor of geoscience, Penn State.

In the United States, nearly 2.6 million couples have been treated for infertility with about 40 percent of those cases thought to be due to male infertility. Now, a study published in the August 22 issue of Cell identifies a new protein that is required for a sperm to bind to an egg during the process of fertilization. This research provides important new insight into the molecular mechanisms that are involved in the initial events of sperm-egg association and may shed light on what underlies some i

Researchers at the Universities of Essex and Bristol will soon be launching a ground-breaking project to develop a ‘conscious’ robot.

The aim of the project, which involves computer scientists and neuropsychologists, is to advance the technology of intelligent machines, while also extending the understanding of human consciousness.

Owen Holland, Senior Lecturer in Computer Science, who will lead the three-year project at Essex, explained: ‘Consciousness is perhaps the last r

Whilst western Europe is feeling the effects of global warming, a “freeze” has come to the rescue of quantum computing.

Quantum Computers – computers so fast they could break any code devised for a digital computer – have a fatal flaw which has until now made it impossible to build really fast quantum computers. They make so many operations that very rare and tiny errors occur rapidly and are amplified, making them unable to function properly.

Artemisinins are one of the only treatments for drug resistant forms of the malaria parasite. Drug resistant parasites are found in most parts of the world, and kill millions of children every year. Even though artemisinins have been used for decades to treat patients with malaria, no one knew how they worked. Now scientists at St George’s Medical School have discovered how artemisinins attack the malaria parasite. After years of clinical and laboratory based research, Professor Sanjeev Krishna and
