Rare sighting of jet from a star-eating black hole
Over 8 billion years ago, a star was torn apart getting too close to a supermassive black hole. Jets of gas recently made the fate of the star visible to a telescope looking for new sources of light in the night sky.
International researchers were welcomed at a reception in Stockholm City Hall at the end of November. Stockholm and Sweden are at the forefront of supporting science and equality, according to researchers attending the reception.
A new study shows how plants “encode” specific chemistries of their lignin to grow tall and sustain climate changes: each plant cell uses different combinations of the enzymes LACCASEs to create specific lignin chemistries. These results can be used both in agriculture and in forestry for selecting plants with the best chemistry to resist climate challenges.
Previous studies have shown that widows and widowers run a higher risk of dying themselves, compared to those of the same age whose partner is still alive. This is often referred to as the ‘widowhood effect’. A new thesis from Stockholm University shows that excess mortality is higher among widowers with a higher socio-economic status compared to other widowers. For widows, it is the other way around – the risk of dying is greater among those who are worse off.
In contrast to what many believe, Swedish men and women with higher incomes have more children, new research from Stockholm University shows. This pattern is particularly clear for men and grows stronger over time: the more money, the more children. But after four children, things change.
