Worrying Signs of AMR Detected in Elderly Care Facilities

A new study published today, analysing wastewater samples from several aged care and retirement homes in Adelaide, has uncovered worrying signs of antimicrobial resistance (AMR) in at least one facility.

Genes Involved in Coronary Artery Disease Identified

Scientists have identified nearly a dozen genes that contribute to calcium buildup in our coronary arteries that can lead to life-threatening coronary artery disease, a condition responsible for up to 1 in 4 deaths in the United States.

Commercial Whaling in the 20th Century Had a Lasting Impact on Diversity Levels

Commercial whaling in the 20th century decimated populations of large whales and also appears to have had a lasting impact on the genetic diversity of today’s surviving whales.

Gut Bacteria Found in Wild Wolves Could Improve Domestic Dogs’ Health

Gut microbes with characteristics of a probiotic found in wild wolves may be the key to alleviating a debilitating gastrointestinal condition common to domestic dogs.

New Enzyme Discovered That Helps Cells Fight Genomic Parasites

Genomic parasites in the form of transposable elements have no specific function but can be dangerous. A new enzyme has been identified that prevents their spread.

Gene That Increases Inflammation Risk Is Carried by Millions

Researchers have found that a genetic change that increases the risk of inflammation, through a process described as ‘explosive’ cell death, is carried by up to 3% of the global population.

New Cellular “Mini-Organ” Identified

Cell biologists describe a new organelle present in mammalian cells that is made of rings of DNA. This “mini-​organ” could potentially play a role in autoimmune diseases, and it could help researchers to understand how cell nuclei evolved.

Why Are Carrots Orange?

A new study of the genetic blueprints of more than 600 types of carrot shows that three specific genes are required to give carrots an orange color. Surprisingly, these three required genes all need to be recessive, or turned off.
