Biomedical engineers at Columbia Engineering have successfully grown fully functional human cartilage in vitro from human stem cells derived from adult stem cells in bone marrow tissue.  Some…

The genomics revolution has been going on for decades, but half of known eukaryote lineages remain unstudied at the genomic level. A new survey, with results published in of Trends in Ecology and…

While our chromosomes are relatively stable within our lifetimes, the genetic material found in our mitochondria is highly variable across individuals and may impact upon human health, say…

Some genetic diseases caused by an abnormal repeat in the DNA are known to become more severe with each new generation - this dreadful trait is called anticipation. Now a study by Portuguese…

Chronic pain is an unknown issue with unknown causes and a subjective definition but some people clearly have it. Researchers recently analyzed 2,721 people, all taking prescription opioid pain…

In biology, anticipation is the term for genetic diseases caused by an abnormal repeat in DNA that becomes more severe with each new generation. Now there is a twist. A study has found the existence…

All organisms, from mammals to fungi, have daily cycles controlled by a tightly regulated internal clock called the circadian clock. The circadian clock is influenced by exposure to light and…

Cardiovascular disease often causes the heart to work harder than usual, a condition that triggers the chronic buildup of cardiac pressure and the onset of heart failure. A new study now shows that…

A genetic study of brown bears (Ursus arctos) in Bulgarian mountain regions showed they originated in Carpathia. So how did they get to Bulgaria? It wasn't natural dispersal.  Bulgarian and…

Some long non-coding RNAs can give rise to small proteins that have biological functions, according to a recent study that describes how researchers have used ribosome profiling to identify several…
