On the left, an optical image from the Digitized Sky Survey shows Cygnus X-1, outlined in a red box.  Cygnus X-1 is located near large active regions of star formation in the Milky Way, as seen in this image that spans some 700 light years across. An artist's illustration on the right depicts what astronomers think is happening within the Cygnus X-1 system.  Cygnus X-1 is a so-called stellar-mass black hole, a class of black holes that comes from the collapse of a massive star.  New studies with data from Chandra and several other telescopes have determined the black hole's spin, mass, and distance with unprecedented accuracy.

Black holes and other star remnants

Imagine a dog owner with a reflective vest and a black dog without one. In the dark we can see how the dog owner moves, but not the dog. That’s how black holes work, too.

Exposing fake news on social media

Facebook is an important source of not only genuine, but also fake news. But now a new tool has been developed to expose the fakers.

People’s drinking habits around Europe have been charted in the recently completed European Social Survey. Alcohol consumption in European countries varies widely. Men consumed almost twice as many units of alcohol as women, and women in Israel and Central and Eastern Europe drink the least. Illustration: Thinkstock

Who in Europe drinks the most?

For the first time, researchers have found a way to compare how much alcohol Europeans drink. And Britain, Ireland and Portugal top off the list.

Pollen may impair pupils’ exam performance

Pollen allergies cause secondary school pupils to do worse on their exams. This can in turn decrease their chances of pursuing their higher education dreams, according to research from NTNU.

Finding life — and farming minerals — deep under the sea

Japanese researchers have access to the largest scientific vessel ever constructed, one that has a 120 metre tall derrick capable of drilling to 7500 metres below the seafloor. They’re using it to hunt for life deep under the seafloor and explore for mineral deposits at the bottom of the ocean — topics that are of great interest to Norwegian researchers.

Cooled patients are treated differently

What is the best form of first aid for a cold, injured body? Mountain medicine researchers are now co-operating to find the answer. At present there is actually no “best practice” for treating this type of patients.

Does ‘green energy’ have hidden health and environmental costs?

Production of electricity is responsible for about a quarter of global greenhouse gas emissions, and demand is poised to rise as underserved populations connect to the grid, and electronics and electric vehicles proliferate. So stopping global warming will require a transformation of electricity production. But it is important to avoid various environmental pitfalls in this transition, researchers say.

Norway’s oldest ice found in Jotunheimen

Some of the ice in the Juvfonne glacier in Jotunheimen National Park in central Norway has been dated to be 7600 years old, currently the oldest dated ice on mainland Norway.

Air could be the world’s next battery

Storing compressed air in sealed tunnels and mines could be a way of storing energy in the future – if an EU project in which Norway is a partner is successful.

Water reservoirs save lives and create value

While there is considerable opposition to dams and reservoirs in the Western world, reservoirs built to store water during the rainy season so it can be used during the dry season can save lives and secure values when the rains fail.

New allergy test promises safer antibiotic use

Allergies to antibiotics are the commonest form of medication allergies and, in the worst cases, can result in anaphylaxis and death. SINTEF is participating in the development of a new allergy test that will make it easier to provide patients with safe and correct treatments.
