Researchers collaborated to derive a transcriptomic signature of aging, which they confirmed using large transcriptomic databases. They discovered that aging in nematodes is partially programmed and can be therapeutically reversed by a number of FDA-approved drugs.

Working with bacteria, a multidisciplinary team at the University of California San Diego has provided new insight into a longstanding question in science: What are the underlying mechanisms that control the size of cells?

Scientists have found that bowel cancer is actually five distinct diseases, with different biological characteristics which affect how they respond to drugs. The new genetic test can diagnose a person’s specific type of bowel cancer in a matter of hours and help tailor treatments to each individual disease.

Genome-wide association studies (GWAS) look at large populations to find genes that contribute to common, multi-gene traits like height or obesity. These comprehensive studies frequently turn up large numbers of tiny genetic variations that occur more often in people who are tall, obese, etc. So which genes should scientists investigate further?

In recent years, numerous studies have shown that people who don't get enough sleep are at greater risk of stroke and heart attack. A study found that people who sleep fewer than 7 hours per night have lower blood levels of three physiological regulators, or microRNAs, which influence gene expression and play a key role in maintaining vascular health.

If a genetically or synthetically engineered organism is released into the environment, how will we know? How can we tell it apart from the millions of microorganisms that exist naturally in the wild? Researchers are now developing a biosecurity tool that can detect engineered microorganisms based on their unique DNA signatures.

The world’s first study on whether genetic variations are involved in the post-traumatic headache experienced by some people following concussion is underway at QUT, funded by a $250,000 US Department of Defence grant.

The evolutionary use of colour for mammal’s survival in the wild is evident from, red foxes, to zebras. In a major scientific breakthrough study, scientists reveal the evidence of colourful pigments from ancient mouse remains.

A research team has now developed "Signal Amplification by Exchange Reaction" (SABER), a highly programmable and practical method that significantly enhances the sensitivity as well as customization and multiplexing capabilities of Fluorescence in situ hybridization analysis.

Researchers have found that while both bonobo and chimpanzee mothers will advocate for their sons in male-on-male conflicts, bonobo moms go the extra mile to aid their sons’ copulation efforts.
