How are galaxies formed?
Astrophysicist Peter Laursen takes you on a step-by-step journey through galaxy formation – from primordial collapse to the formation of spiral arms.
Our bodies do not take up all the calories we ingest. New research indicates that certain people are protected from weight gain simply because a significant part of their calorie intake ends up going down the toilet drain.
Your immune cells can be found everywhere in your body and without hesitating they will fight against any intruder to ensure your well-being. But how much do you know about your immune system and the way your immune cells handle infections like COVID-19?
COMMENT: The first years of life are crucial for the rest of life. Still, too many infants and toddlers are largely not periodically screened to measure their communication, motor, cognitive, social and emotional skills in Denmark, and therefore you might not be swiftly identifying the children who deserve extra help, writes an American pediatrician.
COMMENT: Future maps of roads and cities will be made by an artificial intelligence that may very well have only seen a small part of the world. This can result in a geo-cultural bias that can make the world more unequal.
OPINION: The EU as a whole has committed to ensure that 32% of its energy consumption comes from renewable sources by 2030 but individual targets for member states towards this goal are not binding. Still, there are other ways for the EU to ensure compliance by member states.
Around the year 1900, the third plague pandemic raged. This paved the way for several major changes in society and interacted with developments that were already underway. Perhaps this will also be the case with the present crisis, a history researcher writes.
Quinoa is exceptionally nutritious and robust – it even withstands extreme conditions of drought and salinity. A large new research project wants to uncover the mechanism that makes quinoa so resilient. This is meant to create the basis for future improvement of this unique plant.
COMMENT: It is nice when complex things can be reduced to something simpler. But sometimes you lose more than you gain – such as, for example, when scientific studies are violently shoehorned into two simple boxes: ‘significant’ and ‘nonsignificant’.
The H-index is an attempt at measuring the productivity and impact of researchers. This is an illustration of the universities’ shift from trusting researchers towards micromanagement, efficiency and competition.
American researchers have given concrete estimates as to what extent physical activity is able to reduce the risk of breast and colon cancer. The goal is that doctors will one day prescribe physical activity to patients the same way as they do regular medication. However, Danish researchers are more hesitant.
COMMENT: Private companies and public sectors collect our data every day and minute. In a democratic society, we need to teach children to become critically aware and understand how data processing and digital technologies really work.
Seagrass plants have an excellent capacity for taking up and storing carbon in the oxygen-depleted seabed, where it decomposes much slower than on land. This oxygen-free sediment traps the carbon in the dead plant material which may then remain buried for hundreds of years.
The letter is signed by more than 650 academics from a number of research fields in Denmark. They are calling for universities to lead by example, and implement climate friendly policies in the workplace in the hope of inspiring change in other sectors.
