Evolutionary link between diet, stomach acidity An analysis of data on stomach acidity and diet in birds and mammals suggests that high levels of stomach acidity developed not to help animals break down food, but to defend animals against food poisoning. The work raises interesting questions about the evolution of stomach acidity in humans, and how modern life may be affecting both our stomach acidity and the microbial communities that live in our guts.
Bioethicists call for end to 'pay-to-play' clinical research Charging people to participate in research studies is likely to undermine the fundamental ethical basis of clinical research, according to a new paper written by bioethicists. The paper outlines the arguments for and against the concept of "pay-to-play" research, ultimately concluding that this type of approach compromises the overall integrity of clinical research
Colonoscopies of the future: Adjustable-focus endoscope helps to reduce discomfort An endoscopic probe that delivers adjustable-focus capabilities in a slimmer package has been developed by researchers. The findings could ultimately facilitate more effective and less painful imaging of internal tissues.
Climbing a tree can improve cognitive skills, Climbing a tree and balancing on a beam can dramatically improve cognitive skills, according to a study.
