A study on savannah-living chimpanzees suggests the need to move safely on thin tree branches could explain why early hominins that could walk upright kept their tree-climbing adaptations.

Researchers followed 1,735 people in Denmark over 10 years after their loss of loved one. 6% participants showed unabatingly high levels of grief symptoms, and these had a 88% higher hazard rate of dying from any cause over the time period than those with persistently low symptoms. The first group were likewise more likely to use healthcare services, with 186% higher odds of receiving talk therapy or other mental health services, and between 160% and 463% higher odds of being prescribed psychotropic medication. This is the first study on the long-term mortality rate and the use of healthcare in a large-scale cohort of bereaved persons. The results suggest that patients at risk for long-term ‘high grief’ may be identified in advance, and need additional support from the healthcare system.

Researchers analyzed data from 27,656 Americans between 23 and 43 years old in the ADD Health study. They found that participants reporting to have poor or worse hearing had significantly lower educational attainment, a lower probability of being in paid work, and earned less than their peers. These negative impacts of hearing loss were especially pronounced for Black and Hispanic Americans. Suffering from tinnitus was not found to have any effect on these outcomes. The authors propose better access to hearing care, early screening, and workplace support, as well as reducing stigma, to level the playing field for people with hearing loss.

Scientists have identified the human gene SDR42E1 as essential for the absorption of vitamin D from the intestine, its subsequent metabolic processing, as well as the production of lipids and steroids. Without the functional protein, the survival of cells dropped by 53%. This discovery has at least two potential applications in precision medicine. First, the experiments showed that the gene can be blocked to selectively kill cancer cells. Second, boosting SDR42E1’s expression could help treat many other diseases, for example, autoimmune and metabolic disorders, against which vitamin D and its related forms are thought to protect.
