Researchers have mapped the most common bacterial cause of pneumonia around the world and revealed how these bacteria evolve in response to vaccination.

Changes in the concentration of specific transfer RNAs, a major class of noncoding RNA, are associated with epilepsy. The findings suggest that tRNA fragments could serve as an early warning system for predicting seizure risk.

Synthetic biologists look to re-engineer cells to make complex molecules for specific needs, including pharmaceuticals. But the trial-and-error process is difficult and time-consuming. Now, by combining two state-of-the-art research approaches, researchers have created a fast, efficient way to engineer and analyze metabolic pathways.

The mouse brain, liver, and pancreas contain populations of cells and proteins with extremely long life spans. This "age mosacism" suggests even greater cellular complexity than previously imagined and has intriguing implications for how we we think about the aging of organs.

Researchers have developed a new technique that uses microneedle patches to collect DNA from plant tissues in one minute, rather than the hours needed for conventional techniques.

A grape variety still used in wine production in France today can be traced back 900 years to just one ancestral plant, scientists have discovered.

In a new report, researchers identify a key gene that could be used as an important genetic resource by wheat breeders worldwide to address the constant challenge posed by Fusarium head blight (FHB).

Sloths once roamed the Americas, ranging from tiny, cat-sized animals that lived in trees all the way up to massive ground sloths that may have weighed up to six tons. The only species we know and love today, however, are the two-toed and three-toed sloths--but paleontologists have been arguing how to classify them, and their ancestors, for decades.

Pediatric surgeon Tracy Grikscheit of Children’s Hospital Los Angeles and colleagues describe the progress and challenges of building new intestinal tissue for babies in need.

A group of scientists have developed a new computational tool, based on the mathematical Graph theory, to infer global, large-scale regulatory networks, from healthy and pathological organs, such as those affected by diabetes or Alzheimer's disease.
