Study finds lower dose of ketamine equally effective in reducing pain

A recent Loyola Medicine study found that reducing the standard dose of IV-administered ketamine in half is as effective as the larger dose in reducing pain in adults. The study involved 98 patients and showed similar results at 30 minutes, with lower adverse event rates in the low-dose group.

Tracing and controlling High Pathogenicity Avian Influenza

Researchers found migratory birds from Europe introduced the HPAIV H5N8 virus to Japan. The team also investigated two human anti-influenza drugs, baloxavir marboxil and peramivir, which improved survival rates in infected chickens and reduced viral amounts.

Analysis of "virtual" pollinator trade reveals global dependence on biodiversity for food consumption

Developed countries heavily rely on imported pollination services from developing nations with high crop export rates, indicating a global dependence on biodiversity. Countries that export most pollinator-dependent crops also experience fastest cropland expansion and highest biodiversity decline rates.

Microbes may hold the key for treating neurological disorders

New research suggests that microbes in the gut contribute to symptoms associated with complex neurological disorders, and modulating the gut microbiome improves social behavior but not hyperactivity. The study opens the possibility of treating other conditions like cancer, diabetes, and viral infections with microbiome-targeted therapies.

Riding the wave to memory-forming genetics

Researchers found 300 genes associated with neural oscillations, including hub genes that control separate gene networks. Surprisingly, several of these hubs were active in glial cells, which support and protect nerve cells. This discovery provides an entry point for further research into the underpinnings of human memory.

Long-accepted theory of vertebrate origin upended by fossilized lamprey larvae

New fossil discoveries of over 300 million-year-old lampreys have upended the long-held theory on vertebrate origin, showing that ancient lamprey hatchlings were unlike their modern larvae counterparts. The findings suggest that extinct armored fishes might represent better candidates for the root of the vertebrate family tree.
