Less COVID-19 transmission seen in countries with more intense testing

A study of 173 countries found that increased testing intensity reduced COVID-19 transmission by 9%. Testing had the greatest influence among interventions, with a tenfold increase in tests to new cases reported reducing transmission. This explains why some countries, like China and Australia, achieved near elimination of COVID-19.

LGB adults may be less likely to take statins to prevent heart disease

A new study found that LGB adults are less likely to take cholesterol-lowering medicines, known as statins, to prevent cardiovascular disease. The research suggests that LGB individuals may be unaware of their cardiovascular disease risk and the protective effect of statins due to lower healthcare access and awareness.

Continents prone to destruction in their infancy, study finds

The study reveals that the release of internal primordial heat caused large melting in the shallow mantle, extruding magma onto the Earth's surface. This led to the formation of keels of the first continents and made them weak and prone to destruction. The process resulted in the emergence of life on Earth.
