Histones are tiny proteins that bind to DNA and hold information that can help turn on or off individual genes. Researchers at Karolinska Institutet have developed a technique that makes it possible to examine how different versions of histones bind to the genome in tens of thousands of individual cells at the same time.

For people with non-alcoholic fatty liver disease, exercise not only improves physiology, it may also improve their smile—by reducing gum disease.

Researchers at the University of Calgary and The Hospital for Sick Children (SickKids), in Toronto, have discovered genetic risk factors for OCD that could help pave the way for earlier diagnosis and improved treatment for children and youth.

Using the pollen beetle Brassicogethes aeneus and its host crop oilseed rape as a model crop-pest system, researchers have examined how RNAi efficacy depends on the duration of dietary exposure to dsRNA. This observation has important implications for optimizing dsRNA spray approaches to managing crop pests.

A new 160-million-year-old arboreal pterosaur species, dubbed "Monkeydactyl", has the oldest true opposed thumb - a novel structure previously not known in pterosaurs.

Scientists found six sex chromosomes in the Odorrana swinhoana frog species endemic in Taiwan, giving new insights into how complex XY systems evolve.

An international team reports the findings of an independent assessment of five commercially available assays for tumor DNA sequencing – a fast, cheap and less invasive method to diagnose and monitor cancer.

A new test that measures the quantity and quality of inactive HIV viruses in the genes of people living with HIV may eventually give researchers a better idea of what drugs work best at curing the disease.

A team of researchers has combined a wide variety of data and developed a new algorithm using machine learning technology to identify 165 previously unknown cancer genes.

A "first-of-its-kind" study by researchers at Rutgers University and the University of Oslo has found that overfishing is not likely to be causing evolutionary changes and early maturation in the Atlantic cod fish population.
