Height in early adulthood is an indicator that integrates across different dimensions of sustainable human development with links to health and longevity, nutrition, education and economic productivity.

Measuring HIV-1 DNA levels at the time of stopping antiretroviral therapy (when initiated during primary infection) predicts clinical progression and the time taken for plasma viraemia to become detectable.

The findings have a major impact in understanding the different reward systems involved in two types of addictive behavior, and these advances have implications for prevention and treatment.

Among the factors that predict fitness in wild baboons, dominance rank in males, but not in females, is the best predictor of epigenetic aging.

Single-molecule analysis of SARS-CoV-2 RNA identifies significant heterogeneity in cellular viral RNA levels and highlights slower replication kinetics for the Alpha variant compared to the Victoria strain.

Trajectories of adolescent drinking behavior between age 14 and 19 years can be predicted from bilateral striatal and cerebellar grey matter at 14 years of age.

Embryonic fate-mapping approaches in zebrafish, Xenopus and lamprey illuminate the evolutionary origins of carotid body glomus cells and pulmonary neuroendocrine cells.

Two new polymorphic structures of recombinant human alpha-synuclein fibrils show striking differences to previous structures, while familial PD mutation sites remain crucial for protofilament interaction and fibril stability.

Plasmodium falciparum K13 mutations confer resistance to the antimalarial artemisinin in Asian and African parasites, with most gene-edited mutant K13 African parasite lines showing a fitness cost that may predict slow dissemination of artemisinin resistance in high-transmission settings.

Older people can recruit additional brain regions to help perform complex tasks, possibly compensating for age-related changes in other parts of the brain.
