Genetics

Junk RNA key to maintaining muscle quality?

miRNA, which was once regarded as useless DNA, turns out to be crucial for muscle cell development.

Adults tested for ADHD symptoms in huge study

In the largest ever study of ADHD symptoms in adults, 85,000 blood donors will help scientists figure out if the disorder is hereditary.

Stressed foetal cells harbour hope for cancer treatment

The body’s cells have a mechanism that helps them attain perfect cell division. Cancer cells also use these mechanisms, but scientists are now trying to prevent them from doing so.

Four new type 2 diabetes risk variants identified

Scientists have discovered four previously unreported genetic variants affecting the risk of type 2 diabetes. One of them lowers the risk of developing the disease.

Genes determine effect of diet and exercise

Your genetic makeup helps determine how much you get out of dieting and exercising. A researcher now aims to identify the genes that determine the effect that diabetes patients get from diet and exercise.

Study explains why H1N1 flu can cause narcolepsy

New study explains why many people were affected by narcolepsy during the swine flu epidemic in 2009. The discovery may lead to improved diagnoses and better treatment.

Hummingbirds can fly with almost no oxygen

The hummingbird’s super-fast wing beats are among the most energy-intensive movements in the animal kingdom. Still, the birds can fly 4,000 metres above sea level, where there is very little oxygen. Scientists have now figured out how this is possible.

New asthma susceptibility gene identified

Scientists have identified a gene that helps trigger asthma attacks in children. The gene has no effect on asthma in adults. The discovery thus confirms the hypothesis that ‘asthma’ covers a variety of diseases.

Political colour is half genetic

New study provides definitive evidence that heritability plays a significant role in the formation of political ideology, regardless of how ideology is measured, the time period or population sampled.

Surviving ash trees help to address evolutionary riddle

A pathogenic fungus is killing thousands of European ash trees every year. Danish researchers are now trying to uncover the genetics behind the unknown defence mechanism in ash trees. Not only to save the ash trees, but also to address an evolutionary mystery in trees.
