The Lancet: Study estimates that, without vaccination against 10 diseases, mortality in children under five would be 45% higher in low-income and middle-income countries

A new study estimates that vaccination against 10 major pathogens will have prevented 69 million deaths in low-income and middle-income countries between 2000 and 2030. Vaccination programs are expected to reduce mortality from these diseases by 72% for those born in 2019, with the greatest impact on children under five.

Newly licensed autistic drivers crash less than other young drivers

A study found that young autistic drivers have lower rates of moving violations and license suspensions, as well as similar crash rates compared to non-autistic peers. However, they were more likely to be involved in crashes while making left- or U-turns and failing to yield for other vehicles or pedestrians.

Rumen additive and controlled energy benefit dairy cows during dry period

New research from the University of Illinois shows that consistent energy levels and rumen-boosting supplement monensin are ideal during the dry period for dairy cows. The study found no significant difference in cow performance or metabolic indicators between controlled-energy diets and variable energy diets.

Frequent cannabis use by young people linked to decline in IQ

A study found that frequent cannabis use by young people is associated with a decline in Intelligence Quotient (IQ) points over time. The decline was primarily related to reduction in verbal IQ scores, potentially affecting performance in school and future employment prospects.

NTU study finds Singapore public less keen on drone use in residential areas than industrial zones

A study by NTU Singapore found that the Singapore public is more accepting of drones in industrial zones than residential areas. The research team identified fears and concerns, such as privacy loss and misuse of drones, as key factors influencing public acceptance. To improve acceptance levels, policymakers and regulators should adapt...

Eyes reveal life history of fish

Scientists have created a technique using stable isotopic analysis of eye lenses to reveal a fish's life history and diet. The study found that fish on floodplains grew faster and had different dietary signatures than those in rivers or hatcheries, providing valuable insights for managing habitats and conservation efforts.

An ancient economy

A team of archaeologists has discovered that the Chumash Indians in California were using shell beads as currency around 2,000 years ago. The team's findings, published in the Journal of Anthropological Archaeology, challenge long-held assumptions about the origins of money in the Americas.
