Using a beam of light shunted through a tiny silicon channel, researchers have created a nanoscale trap that can stop free floating DNA molecules and nanoparticles in their tracks. By holding the nanoscale material steady while the fluid around it flows freely, the trap may allow researchers to boost the accuracy of biological sensors and [...]
Scientists have new information about the complex genetic signature associated with Alzheimer’s disease, the leading cause of cognitive decline and dementia in the elderly. The research uses a powerful, high-resolution analysis to look for genes associated with this devastating neurodegenerative disorder.
Malarial parasites found in tree-dwelling African thicket rats share a close evolutionary relationship with Plasmodium falciparum and P. reichenowi. The analysis is based on amplification of entire mitochondrial genomes of malarial parasites that use humans, rodents, birds and lizards as their hosts.

While examining patterns of DNA modification in lung cancer, scientists have discovered what they say is a surprising new mechanism. They say that “silencing” of a single gene in lung cancer led to a general impairment in genome-wide changes in cells, contributing to cancer development and progression.
Since the Last Glacial Maximum (LGM; about 21,000 years ago) sea level has risen by 130 meters (430 feet), resulting in continental shelf submergence and a massive expansion of the surface area of shelf seas.
Everybody is familiar with the stereotypes of medical education from the student perspective: grueling hours, little recognition, and even less glory. A new study pulls back the curtain on the dominant environment of academic medicine from the perspective of faculty, the providers of medical education in medical schools. The study raises questions about how the [...]
Engineers have developed a new, highly efficient way to pair up cells so they can be fused together into a hybrid cell. The new technique should make it much easier for scientists to study what happens when two cells are combined. For example, fusing an adult cell and an embryonic stem cell allows researchers to [...]
Scientists have identified a variation in a particular gene that increases susceptibility to early coronary artery disease. For years, scientists have known that the devastating, early-onset form of the disease was inherited, but they knew little about the gene(s) responsible until now.

Micro-organisms in the intestine live in symbiosis with humans but can cause illness or even death. Scientists have researched the factors that make a person immune to worm infections. The knowledge can now be used to develop vaccines.

Scientists have identified a protein produced by cancerous lung epithelial cells that enhances metastasis by stimulating the activity of inflammatory cells.
