Methods in belowground botany

Plant root systems play a crucial role in ecosystems, radically impacting everything from nutrient cycling to species composition. Despite their importance, scientists are just beginning to develop the tools to understand ...

Researchers find mechanism that regulates telomeres

The tips of chromosomes have structures called telomeres comparable to the plastic cover at the end of shoelaces. They work as a protective cap that prevents genetic material from unfolding and corroding. When telomeres do ...

Structure of fat-processing enzyme determined

After decades of work with no success, researchers have determined the high-resolution, three-dimensional structure for lipoprotein lipase, the enzyme that processes fats, or triglycerides, in the bloodstream and releases ...

Src regulates mTOR, a major player in cancer growth

A team of researchers at Baylor College of Medicine and Texas Children's Hospital has revealed a connection between mTORC1 and Src, two proteins known to be hyperactive in cancer. The study, published in the journal Nature ...

New genetics tool helps answer evolutionary questions

The age of big data is here. Thanks to innovations in genetic sequencing technology, scientists can now generate massive datasets describing the genomes of Earth's diverse set of species. This ever-growing genomic encyclopedia ...
