Strong emotions plus non-REM sleep equals longer-lasting perceptual memories


Perceptual memories linked to positive emotions, such as joy or happiness, are strengthened during sleep, specifically during periods of deep non-REM sleep.

Eco-friendly ammonia production for fertilizers and alternative fuel


A new process that allows ammonia to be produced using much less energy than the standard methods.

AI identifies features associated with cancer recurrence


Artificial intelligence has successfully identified features relevant to cancer prognosis that were not previously noted by pathologists

Detecting pathogens: the evolution of plant immunity


Scientists find recognition receptors for plant growth and plant immunity that share a common evolutionary origin.

Social novelty in the brain: haven’t I seen you someplace before?


Social novelty and contextual novelty are segregated in the SuM region of the hypothalamus and in projections to the hippocampus, allowing memories of meeting new people to be formed separately from memories of new places.

Running away from carbon dioxide: the terminal connection


Even fish want to avoid carbon dioxide. Now we know that they can because of chemosensation and the Terminal Nerve.
