A Viewpoint published in The Lancet disputes reports of NHS decline in productivity. Quality improvement was found to be significantly higher than initially thought, with notable gains in areas like critical care and patient experiences. This challenges the narrative of declining healthcare productivity in England.
A team of researchers has discovered how the protein SAMHD1 protects immune cells from HIV by starving the virus of necessary building blocks. This finding could lead to more effective anti-HIV drugs and new insights into other viral infections.

The article provides IPM program recommendations for managing the southern pine beetle, a chronic insect pest in southeastern US pine forests. The beetle has three population phases, and an IPM program should be tailored to each phase, with prevention and restoration being primary concerns during the latent phase.

A study published by the American Academy of Neurology suggests that consuming excessive calories may double the risk of mild cognitive impairment (MCI) in individuals aged 70 and above. The findings indicate a dose-response pattern where higher caloric intake corresponds to increased MCI risk.
A new MRI technique allows for non-invasive examination of battery internal workings, enabling testing of various designs and materials under normal operating conditions. This method has the potential to improve battery performance and safety by visualizing build-up of lithium metal deposits on electrodes.
