AU professor joins exclusive club: World-renowned academy invites Bo Barker Jørgensen to join

Professor Bo Barker Jørgensen from Aarhus University is to become a member of the world's most prestigious science academy, the American National Academy of Sciences. The academy only invites researchers with very significant results, and being invited is a unique accolade.

A small leak in the Earth's core

The Earth’s core is not as isolated from the rest of the globe as previously believed. An international research group headed by Aarhus University has discovered that tiny amounts of iron from the core 2,900 km beneath us are seeping into the mantle and all the way up to volcanic islands on the Earth's crust.

Fundings for prediction of COVID-19 infection and clinical severity

The healthcare system and the economy are under pressure in many parts of the world due to the ongoing COVID-19 pandemic. With fundings from Independent Research Fund Denmark Professor Jørgen Kjems will, in collaboration with researchers from DTU and Rigshospitalet, develop a method that can detect the virus at very early stages of infection and,…

The North Atlantic right whale population is in poor condition

New research by an international team of scientists reveals that endangered North Atlantic right whales are in much poorer body condition than their counterparts in the southern hemisphere. The alarming results from this research, led by Dr Fredrik Christiansen from Aarhus University in Denmark, were published this week in the journal Marine…

Icelandic DNA jigsaw-puzzle brings new knowledge about Neanderthals

An international team of researchers has put together a new image of Neanderthals based on the genes Neanderthals left in the DNA of modern humans when they had children with them about 50,000 years ago. The researchers found the new pieces of the puzzle by trawling the genomes of more than 27,000 Icelanders. Among other things, they discovered…

Rice plants in soil without cable bacteria (left) and with cable bacteria (right). The activity of cable bacteria can be clearly seen by the formation of an orange rust crust on the surface of the soil in the rice pot. The bacteria dissolve black iron sulphide in the soil and convert the sulphide into sulphate while the iron wanders to the surface and forms rust when it comes into contact with oxygen.

Cable bacteria can drastically reduce greenhouse gas emissions from rice cultivation

A Danish-German research collaboration may have found a solution to the large climate impact from the world's rice production: By adding electric conductive cable bacteria to soil with rice plants, they could reduce methane emissions by more than 90%.

Life in the oceans could be restored in 30 years: provided we act now

According to an international group of marine scientists, it is not too late to restore the ecosystems in the world's oceans. If we follow their road map and, in particular, get to grips with climate change, we could even achieve this by 2050.
