How our cells repair their damaged DNA

Researchers find important mechanism that allows cells to repair damaged DNA. Could answer questions about cancer development.

Loss of large animals has reduced global circulation of vital nutrients

Decline of large animals such as whales, sea birds, and salmon has led to a loss of 94 per cent of the transportation of nutrients on the planet.

The Black Death has been hiding among us for thousands of years

Fossil DNA reveals that the plague is much older than previously suspected. The discovery could shed new light on the evolution of a deadly disease.

This is what a 50-million-year-old bat looked like

Scientists have for the first time determined the colour of an extinct mammal: a bat that lived 50 million years ago.

Swedish lizards are thriving under rising temperatures

A northern species of lizards are bucking global trends when it comes to climate change. New research shows that they can adapt quickly by laying their eggs earlier.

Scientists find smallest life forms on Earth

Researchers may have found the smallest life forms on Earth. The bacteria they found are much smaller than scientists thought possible.

Searching for answers to a century-old biological question

With the help of 58,046 fruit flies, scientists in Florida and Norway have shed light on a question that biologists have puzzled over for the last 100 years.

Light from distant galaxies can reveal extra-terrestrial life

Physicists can now trace light emitted by plants and microorganisms on planets far away.

New substance attenuates E.coli

An artificial molecule can impair the E.coli-bacteria’s aptitude to cause illness. This may have wider impact than solely for the illnesses this bacteria causes. The discovery may also prove a valuable contribution in the struggle against the increasing threat from antibiotics resistance.

Suggesting answers to one of Darwin’s mysteries

Why do we see so little evolution in some fossils?
