The Lancet Healthy Longevity: Study finds racial and ethnic disparities in flu vaccine uptake among people aged 65 and older in the USA

A new study published in The Lancet Healthy Longevity found significant racial and ethnic disparities in the uptake of seasonal flu vaccines among people aged 65 and over in the USA. Among those who received a vaccine, minorities were 26-32% less likely to receive the High Dose Vaccine, which is more effective in older adults.

Global mapping projects aid humanitarian organisations

A study by Heidelberg University researchers found that over 60 million buildings and four million roads were added to OpenStreetMap between 2008 and 2020, primarily in low- and medium-human development regions. However, these areas still account for only a small percentage of mapped data due to socio-economic and demographic factors.

High patient uptake for text message system monitoring opioid use in real-time

A study at the University of Pennsylvania found that 61% of opioids prescribed to patients after orthopedic procedures went unused. The text message system showed high patient uptake, with 88% responding on the fourth day and 95% on the 21st day. Patients reported a decrease in pain levels without using most of the prescribed opioids.

Modeling a better catalyst for PIBSAs

Researchers have developed a computational model to improve the production of polyisobutenyl succinic anhydrides (PIBSAs) for auto industry formulations. The study reveals the detailed mechanism of Lewis acid-catalyzed reactions, enabling faster and more efficient synthesis with reduced energy input.

More sustainable recycling of plastics

Researchers at the University of Konstanz have created a more energy-efficient chemical recycling method for polyethylene-like plastics, recovering around 96% of the starting material. The new process uses 'breaking-points' to deconstruct molecular chains into smaller building blocks, making it suitable for 3D printing applications.
