Quantum-inspired design boosts efficiency of heat-to-electricity conversion
Researchers have found a new way to improve a key element of thermophotovoltaic systems, which convert heat into electricity via light. Engineers designed a thermal emitter that can deliver high efficiencies within practical design parameters.

Scientists find a region of the mouse gut tightly regulated by the immune system
Researchers have analyzed the entire mouse intestine, mapping gene expression and cell states and location in the healthy gut and in response to perturbations such as inflammation. They identified tight regulation of cell types and states in different regions of the organ, as well as a unique segment of the colon that is controlled by immune signals. The findings reveal the surprising adaptability and resilience of the intestine to perturbations and highlight the importance of considering how cell processes are regulated and vary across different parts of a tissue or organ.

Snoring linked to behavioral problems in adolescents without declines in cognition
Adolescents who snore frequently were more likely to exhibit behavior problems such as inattention, rule-breaking, and aggression, but they do not have any decline in their cognitive abilities, according to a new study. This is the largest study to date tracking snoring in children from elementary school through their mid-teen years and it provides an important update to parents struggling with what medical measures to take to help manage snoring in their children.

Study uncovers potential new target for treatment of chronic, debilitating skin disease
Hidradenitis suppurativa (HS) is an immune disease that affects up to 4% of the global population and causes painful, recurring skin lesions and inflammation, primarily in the folds of the skin. It commonly affects women of African American descent.

Less cold: Ocean cold period in the early 20th century less pronounced than previously thought
A new study shows that the oceans were less cold in the early 20th century (1900--1930) than previously thought. During this period the ocean appears too cold due to the way some measurements were taken. This makes global ocean surface temperature measurements during this period inconsistent with both land air temperatures and palaeoclimatic data and the differences between land and ocean are larger than shown in climate models.
