Vitamin B12 accelerates worm development

Everyday our cells take in nutrients from food and convert them into the building blocks that make life possible. However, it has been challenging to pinpoint exactly how a single nutrient or vitamin changes gene expression ...

Scientists re-imagine how genomes are assembled

Scientists at the University of Massachusetts Medical School (UMMS) have developed a new method for piecing together the short DNA reads produced by next-generation sequencing technologies that are the basis for building ...

Study helps to explain how C. elegans worm turns

New research by scientists at the University of Massachusetts Medical School shows at the single cell level how an external stimulus sets off a molecular chain reaction in the transparent roundworm C. elegans, a process in ...

Researchers discover a new role for RNAi

Organisms employ a fascinating array of strategies to identify and restrain invasive pieces of foreign DNA, such as those introduced by viruses. For example, many viruses produce double-stranded (ds)RNA during their life ...

Draft sequence of monarch butterfly genome presented

Each fall millions of monarch butterflies from across the eastern United States use a time-compensated sun compass to direct their navigation south, traveling up to 2,000 miles to an overwintering site in a specific grove ...

Elusive prey

Escape responses are some of the most studied behaviors by neurobiologists who want to understand how the brain processes sensory information. The ability to evade predators plays a vital role in the process of natural selection. ...
