Published today in Science Advances and led by the University of Melbourne, the study provides the first comprehensive estimate of species used and traded across plants, animals and fungi. Previous estimates calculated around 50,000 species were in trade worldwide. However, new analysis which bought together cross-sectorial data on wildlife trade monitoring programs found at least double that, with 107,356 species in use and traded globally.

News Release 30-Oct-2026 Summary author: Abigail Eisenstadt Peer-Reviewed Publication American Association for the Advancement of Science (AAAS) A new Research Resource provides a massive database that documents 25,419 psychedelic experiences recorded through interactions on a support hotline, providing a way to understand psychedelic use outside the clinic. For decades, psychedelic research stalled due to restrictive policies governing the accessibility of psychedelic drugs’ active compounds.

Dark blue stained cells have just been infected. Yellow indicates cells that were infected at an earlier time point.

A new study published in the journal Neuroscience revealed that exhaustive training without adequate rest alters the regulation of dopamine in the hippocampus, a brain region closely linked to memory and the regulation of emotions.

image: Self-supervised training and evaluation workflow. During training, a random subset of valid observations is used as input together with an observation mask; the loss is computed only on valid (observed) locations to avoid supervising on missing pixels. During testing, a disjoint subset of valid observations is withheld as pseudo-ground truth, and metrics are computed only at these withheld locations.

Researchers Duc Duy Nguyen and David Emberson have investigated how efficient use of hydrogen could be the key to releasing ammonia's potential.

Over 100 million people in the U.S. are affected by diabetic retinopathy, a complication of diabetes that affects the eyes. The condition is caused by damage to the blood vessels in the retina, the light sensitive tissue at the back of the eye. At first, diabetic retinopathy might not cause any symptoms, or the problems might be mild. However, if the underlying diabetes remains poorly managed, it can lead to blindness.
