How new bird species arise

Much of a centuries-old debate over where and how new bird species form has now been resolved. Researchers at the University of Copenhagen have provided evidence that birds in mountainous areas—where the vast majority of ...

Studies add to concern about climate tipping

Two model studies document the probability of climate tipping in Earth subsystems. The findings support the urgency of restricting CO2 emissions as abrupt climate changes might be less predictable and more widespread in the ...

Researchers use sunlight to produce chemicals and energy

Researchers at the University of Copenhagen have discovered a natural process they describe as "reverse photosynthesis," by which the energy in solar rays breaks down plant biomass rather than building it, as is the case ...

Researchers confirm that narwhals and belugas can interbreed

A team of University of Copenhagen researchers has compiled the first and only evidence that narwhals and beluga whales can breed successfully. DNA and stable isotope analysis of an anomalous skull from the Natural History ...

When things are at their worst, Christianity is intensely enacted

A new University of Copenhagen PhD thesis has taken a look at faith as practiced in the daily lives of Danish cancer survivors. The thesis shows that Christian beliefs play a significant role in the lives of people suffering ...

Astronomers gain new knowledge about early galaxies

The early galaxies of the universe were very different from today's galaxies. Using new detailed studies carried out with the ESO Very Large Telescope and the Hubble Space Telescope, researchers, including members from the ...

Danish chemists in molecular chip breakthrough

Electronic components built from single molecules using chemical synthesis could pave the way for smaller, faster and more green and sustainable electronic devices. Now for the first time, a transistor made from just one ...

Environmentally friendly cement is stronger than ordinary cement

New research from the Niels Bohr Institute shows that cement made with waste ash from sugar production is stronger than ordinary cement. The research shows that the ash helps to bind water in the cement so that it is stronger, ...
