Researchers found that topography influences comet surface activity across hundreds of meters, with hotspots observed even on uniform surfaces. The study used Rosetta mission data to track changes in 16 topographic depressions on Comet 67P.

Would helping only the least advantaged benefit society as a whole?

A study by Hun Chung questions the assumption that helping the least advantaged benefits society as a whole, finding potential gaps in Rawls' theory. The research suggests that even with an optimal state, further improvements can occur without worsening the situation of the least advantaged group.

Reasons for hospital admissions in people with type 2 diabetes are changing

Researchers found that people with type 2 diabetes are being admitted to hospital at greater frequency for non-traditional complications, including infections and mental health disorders.
