Opossum DNA provides new insight into natural selection

Study of the DNA of a South American marsupial called the opossum has revealed that a gene's location influences whether or not it is likely to gather changes that could lead to disease.

Origins of modern medicine lie in ancient Egypt not Greece

Scientists examining documents dating back 3,500 years say they have found proof that the origins of modern medicine lie in ancient Egypt and not with Hippocrates and the Greeks.

Structural variation in the human genome

A major new effort to uncover the medium- and large-scale genetic differences between humans may soon reveal DNA sequences that contribute to a wide range of diseases, according to a paper by Howard Hughes Medical Institute investigator Evan Eichler and 17 colleagues published in the May 10, 2007, Nature.

Males have evolved to deliver sperm more effectively to females with multiple partners

A review of the latest research in sexual adaptation shows that evidence is building for what researchers call "sperm competition."

Gene mutation linked to cognition is found only in humans

The human and chimpanzee genomes vary by just 1.2 percent, yet there is a considerable difference in the mental and linguistic capabilities between the two species.

Fluorescent nanoparticles open up new possibilities for cellular imaging

Scientists from the University of Twente, the Netherlands, have successfully exploited the optical properties of fluorescent nanoparticles to broaden the scope of single-cell microscopy.

Plant chemical harmine fights diabetes in mice

After screening hundreds of compounds for their effects on fat development, researchers have discovered that an ingredient found in some plants fights diabetes in mice without some of the side effects attributed to other antidiabetes drugs.

First comprehensive profile of cell movement

Researchers at the University of California, San Diego (UCSD) School of Medicine have developed new technology which, combined with proteomics, the large-scale study of the structure and function of proteins and their functions, has allowed them to map an extensive network of the signaling proteins that control cell movement.

The health effects of climate change in the UK

The Department of Health and the Health Protection Agency have today published an updated report of the Health Effects of Climate Change in the UK .

Little-known cell networks vital to circadian rhythm

Circadian rhythm is the basic 24-hour cycle that involves various behaviors, including sleeping and eating, in all living organisms.

New view of photosynthesis

During the remarkable cascade of events of photosynthesis, plants approach the pinnacle of stinginess by scavenging nearly every photon of available light energy to produce food.

Gene-for-gene interactions help bacteria kill their host

Scientists have discovered that a cousin of the plague bacterium uses a single gene to out-fox insect immune defences and kill its host.

Noise effects in ion channels in the brain are much larger than previously assumed

Addressing a current issue in neuroscience, Aldo Faisal and Simon Laughlin from Cambridge University investigate the reliability of thin axons for transmitting information.

There may be a real code to chromosomal organization

The identification of a cluster of essential genes on mouse chromosome 11 as well as similar clusters on the chromosomes of other organisms , including humans , buttresses the argument that there may be rules as to how genes are structured or laid out on chromosomes, said the Baylor College of Medicine senior author of a report that appears online in the Public Library of Science Genetics, an open-access publication.

Elastic interactions of membrane proteins

Cellular survival relies crucially on the ability to receive and communicate signals from and to the outside world.

Scientists work out mechanism underlying asymmetric cell division in nematode worms

When a cell divides, normally the result is two identical daughter cells. In some cases however, cell division leads to two cells with different properties. This is called asymmetric cell division and plays an important role in embryonic development and the self-renewal of stem cells.
