About The Study: Transparency of evidence supporting Food and Drug Administration (FDA) authorization of artificial intelligence (AI)- and machine learning -based devices for Alzheimer disease and related dementias was limited, precluding effective evaluation of training and validation dataset representativeness. Disease status (i.e., dementia type and distribution), age, and sex were reported for fewer than half of devices, while race and ethnicity data were rarely disclosed, raising uncertainty about real-world generalizability and clinical accuracy in intended populations. 

Scientists from the Milner Centre for Evolution at the University of Bath have found that factors including mating systems and brood size could predict the ratio of males to females for animals bred in captivity.

The study of our animal cohabitants often provides valuable insight into the condition of humanity, but animals have also been a gateway to understanding the natural world. The latest volume of Osiris, entitled “Animal Mobilities,” collects articles on the subject of animal agency and the role of animals in human knowledge production. Studying the movements of animals as individuals, groups, and systems, write guest editors Tamar Novick, Lisa Onaga, and Gabriel N. Rosenberg, “may permit a reexamination of the ethical commitments of both scientific and historical inquiry,” encouraging scholars to more keenly attend to the lives of the creatures that surround them. It may also invite “a reconsideration of how, where, and by whom science is done.”

Coral restoration efforts could be dramatically improved with technologies that support the survival and growth of baby corals, suggests a new study.
