CELL BIOLOGY Researchers from the University of Copenhagen and Aalborg University presents a new study demonstrating that a small molecule in brain cells affects the level of hypocretin, which is responsible for making us feel awake during the day and tired at night. People with a genetic variation of this molecule have a higher risk of suffering from daytime sleepiness.
Forest loss due to anthropogenic activities is one of the main causes of plant and animal species decline.
Behavioral flexibility should, theoretically, be positively related to behavioral inhibition because one should need to inhibit a previously learned behavior to change their behavior when the task changes (flexibility).
In most bird species, females disperse prior to their first breeding attempt, while males remain close to the place they hatched.
Across species, social hierarchies are often governed by dominance relations.

CORONA Young people’s mental health has not been affected by the two corona lockdowns, a new study from the University of Copenhagen concludes. But in the short run, it did suffer temporarily.
Such planetary smashups are likely common in young solar systems, but they haven’t been directly observed.
A new study finds cutting off cells’ supplies of lipids can slow the growth of tumors in mice.
Coral reefs in remote or protected areas can recover quickly after mass coral bleaching events, new research shows.
The ancestors of many animal species alive today may have lived in a delta in what is now China, new research suggests.
SKIN The lipids, or fat molecules, in the skin are significantly different in patients with a certain type of Parkinson’s disease from healthy individuals, a new multicenter study involving the University of Copenhagen finds. The researchers hope the findings could improve early detection of Parkinson’s disease in younger people.
Fossils indicate a communal nesting ground and adults who foraged and took care of the young as a herd, scientists say.
