Genomic and computational tools provide window to distant past

Out of the estimated 23,000 or more genes in the human genome, about 100 of them will differ—they will be present or not—between any two individuals. Genes lost or gained over time result from evolution and adaptation, ...

Research update: Genome editing becomes more accurate

Earlier this year, MIT researchers developed a way to easily and efficiently edit the genomes of living cells. Now, the researchers have discovered key factors that influence the accuracy of the system, an important step ...

Drought response identified in potential biofuel plant

Drought resistance is the key to large-scale production of Jatropha, a potential biofuel plant—and an international group of scientists has identified the first step toward engineering a hardier variety.

New mouse model reveals a mystery of Duchenne muscular dystrophy

Children with Duchenne muscular dystrophy often die as young adults from heart and breathing complications. However, scientists have been puzzled for decades by the fact that laboratory mice bearing the same genetic mutation ...

Biologists simulate a cell in action

(Phys.org) —The inner workings of a cell involve hundreds of thousands of discrete molecules, engaged in a repeating cycle of interactions that sustain life.

Hunger affects decision making and perception of risk

Hungry people are often difficult to deal with. A good meal can affect more than our mood, it can also influence our willingness to take risks. This phenomenon is also apparent across a very diverse range of species in the ...

Computer models shed new light on sickle cell crisis (w/ video)

Using powerful computer models, researchers from Brown University have shown for the first time how different types of red blood cells interact to cause sickle cell crisis, a dangerous blockage of blood flow in capillaries ...
