Scientists studying biological systems at the molecular level now have a new hybrid technique to probe the dynamics of the Holliday junction. The Holliday junction is a four-stranded DNA structure that forms during a process known as homologous recombination, which occurs when damaged DNA is repaired. Understanding how DNA repairs itself is an essential step in ultimately developing therapies for genetic disorders.

A group of scientists, led by mathematicians, has taken on the challenge of building a common model of immune responses. Their work will radically improve our understanding of the human immune system by allowing all the scientific disciplines working on it to have a common reference point and language.

According to reports, American biologist Craig Venter is going to announce that he has created the first ever "artificial life form" on earth at the J. Craig Venter Institute, a U.S. laboratory and research center, using synthetic chromosomes made from chemicals.

Integrating silicon microchip technology with a network of tiny fluid channels, some thinner than a human hair, researchers at The Johns Hopkins University have developed a thumb-size micro-incubator to culture living cells for lab tests.

That clover necklace you make for your child could well be a ring of poison. That’s because some clovers have evolved genes that help the plant produce cyanide – to protect itself against little herbivores, such as snails, slugs and voles, that eat clover.

A growing number of Americans consider global warming an important threat that calls for drastic action, and 40% say that a presidential candidate’s position on the issue will strongly influence how they vote, according to a national survey conducted by Yale University, Gallup and the ClearVision Institute.

A new and deceptively simple technique has been developed by chemists at Vanderbilt University that can measure the interactions between free-floating, unlabeled biological molecules including proteins, sugars, antibodies, DNA and RNA.

A new study by York University biologists Amro Zayed and Laurence Packer has shown that a lone insect can initiate a biological invasion.

Most of the diseases which plague humankind today are multifactorial: they are not simply the result of one mutation in one gene, producing one rogue protein that can no longer carry out its job. Diabetes and obesity, for instance, depend on many simultaneous genetic and environmental factors.

Systems Biology is transforming the way scientists think about biology and disease. This novel approach to research could prompt a shake up in medical science and it might ultimately allow clinicians to predict and treat complex diseases such as diabetes, heart failure, cancer, and metabolic syndrome for which there are currently no cures.

Olympus Corporation and the National Center for Biological Sciences have jointly established the NCBS/Olympus Micro-Imaging Center within the NCBS.

For the first time, findings by scientists at the Genome Institute of Singapore (GIS) may be paving the way for more efficient analyses and tests related to the replication of cells, and ultimately, to the better understanding of human biology, such as in stem cell research.
