The Norse settlements on Greenland was founded by Erik the Red around 985 and lasted almost 500 years. New research show that the settlers hunted walrus and traded tusks and ivory across Europe during the Middle Ages, but the hunt became so intense that it may have led to the collapse of Norse Greenland. 

It's not about the Black Death or the dinosaurs dying out. "The Great Dying" is an event in the geological perspective. The largest of all mass extinctions on Earth. We are at the end of the Permian Period, 252 million years ago.

– Donor milk recipients are the smallest and most vulnerable members of our society. We are obliged to provide them with as good support as we possibly can, says Dr. Hedvig Nordeng at the University of Oslo.

Today, both public enterprises and private companies in the major cities collect large quantities of data about the citizens living in those cities, and most people derive little benefit from this. However, if the citizens own and control their own data, life in the city can be much better.

India’s government claims that the population of tigers in India has reached 2,967 animals – more than a doubling of the 1,411 animals reported in 2006. But there is a problem: The conclusion is not backed by reliable evidence, according to a new scientific paper. 

With the powerful eyes of the Hubble Space Telescope, an international team of astronomers led by Håkon Dahle at UiO observed straight into the bright and hot heart of a galaxy 11 billion years old in no less than 12 multiple, gravitationally lensed images.

The Javan slow loris is a small, furry, big-eyed and apparently cute primate, but the bite is poisonous! A new study shows that the lorises sleep in the same way as humans do, and this indicates that the so-called monophasic sleep pattern is a much older evolutionary trait than previously assumed. 

There are 30 % more sediments on the seabed than previously expected, reveal an update of the map GlobSed. This equates to up to two kilometers of extra land mass over today’s land area. 

“It takes an estimated 27 years to determine if a novel medication can be used by pregnant women without risking adverse effects on the fetus or child. This just can’t continue any longer”, says Professor Hedvig Nordeng at the University of Oslo’s Department of Pharmacy.

Antibiotics most commonly work by killing bacteria, for example by destroying their cell wall or by interfering with protein synthesis. Now researchers at UiO are launching a completely new idea: They want to prevent bacteria from sticking to a substrate, before an infection can even occur.
