Genetics

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.

Potato famine genome secrets unlocked

Using historical botanical collections, scientists have unlocked the genetic code of potato blight – the disease behind the great Irish Potato Famine. New study shows what made the potato famine so ruthlessly dangerous and why it’s still costing billions to fight it.

Why insects always hide in the dark

It is no coincidence that insect larvae always hide away in dark corners. Scientists have now discovered how the larvae know where it’s best to hide away.

Microscopic arms race rages on the seabed

The ocean floor contains viruses and bacteria locked in a constant struggle for survival. This has a great effect on the carbon cycle in the ocean and thus also affects how much CO2 is released into the atmosphere.

Adrenal tumours linked to high blood pressure

High blood pressure can be caused by adrenal tumors triggering hormone overload.

Childhood obesity gene identified

Defects on a special ’satiety gene’ may constitute a rare but important cause of early childhood obesity.

’Allergy genes’ identified

Scientists have identified the ten main genes responsible for inherited allergies. The discovery may also reveal the cause of the rising incidence of type 1 diabetes.
