Fecal microbe transplants from healthy donors can treat patients with recurrent Clostridium difficile infections. However, after tens of thousands transplants, little was known about which donor strains provide long-term engraftment, and which engraft early after the transplant. Most failures of fecal microbe transplantation occur in the first four weeks. Researchers have now found 19 Bacteroides vulgatus genes that were unique to three strains that show early engraftment in patients after a fecal transplant, as opposed to seven strains that did not show early engraftment.

To examine the global state of AI ethics, a team of researchers performed a systematic review and meta-analysis of global guidelines for AI use. The researchers found that while most of the guidelines valued Privacy, Transparency, and Accountability, very few valued Truthfulness, Intellectual Property, or Children's Rights. Additionally, most of the guidelines described ethical principles and values without proposing practical methods for implementing them, and without pushing for legally binding regulation.

Relief could be on the way for people with painful hand osteoarthritis after a new study found an affordable existing drug can help. Until now there has been no effective treatment. The paper investigated methotrexate, a low-cost, effective treatment for inflammatory joint conditions such as rheumatoid arthritis and psoriatic arthritis. It has been widely used in Australia and globally since the early 1980s.
