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.
