New look at archaic DNA rewrites human evolution story

A University of Utah-led team analyzed archaic DNA to reconstruct the early history of humans, revealing an evolutionary story that challenges traditional views. The study found that Neanderthals and Denisovans nearly went extinct after separating from modern humans, but later diverged and grew into tens of thousands of individuals.

Teen brains may not be as hard-wired for crime as previously thought

A study of age and crime statistics from Taiwan suggests that cultural factors, such as collectivist societies and parental supervision, may influence the age-crime relationship. The findings challenge the long-held assumption that biology drives teen criminal behavior, instead highlighting the importance of cultural influences.

Neurobiology: Lessons by post

A dedicated transport system has been characterized that delivers specific mRNAs to active synapses, allowing for the modulation of synaptic junctions and enabling learning and memory. The key factor involved in this transport binds specifically to regions of its mRNA cargo lacking protein-coding information.

A hard bargain

Two studies led by Harvard Medical School researchers found that few people actually use price shopping tools to choose lower-cost healthcare options, despite growing interest in the idea. The research suggests that consumerism may not be as effective as believed in driving down healthcare costs.

DNA from Viking cod bones suggests 1,000-year history of European fish trade

A new study suggests a European stockfish trade existed for 1,000 years, with cod bones from Haithabu providing evidence of fish caught in northern Norway being consumed on mainland Europe. The findings support the idea that traded fish played a significant role in knitting the European continent together economically.

Fat rats show why breast cancer may be more aggressive in patients with obesity

A study published in Hormones & Cancer found that obese rats with sensitive androgen receptors had more aggressive tumors, even after anti-estrogen treatment. Researchers identified inflammation and cytokine interleukin 6 as key factors contributing to this sensitivity, highlighting the potential for personalized therapeutic strategies.

Molecule in human saliva has potential for wound healing

A study published in The FASEB Journal found that the salivary peptide histatin-1 promotes angiogenesis, a critical process for efficient wound healing. Histatin-1 was also shown to increase cell adhesion and migration, opening new avenues for understanding oral wound healing and potentially improving treatments for other types of wounds.

Study links malaria rapid diagnostic tests to more antibiotic use and finds ignored results

A new study published in the American Journal of Tropical Medicine and Hygiene found that rapid diagnostic tests for malaria are reducing the need for antimalarial medications but may also lead to an increase in antibiotic prescriptions. The research analyzed over 500,000 patient visits across malaria-endemic regions and revealed that ...
