Study explores the cell-type-specific effects of aging and sex on human cortical neurons
Aging is known to have profound effects on the human brain, prompting changes in the composition of cells and the expression of genes, while also altering aspects of the interaction between genes...
Catalyst design boosts performance of anion-exchange-membrane fuel cells
Fuel cells are energy-conversion solutions that generate electricity via electrochemical reactions without combustion, thus not contributing to the pollution of air on Earth. These cells could power...
Study predicts a new quantum anomalous crystal in fractionally filled moiré superlattices
Moiré superlattices, structures that arise when two layers of two-dimensional (2D) materials are overlaid with a small twist angle, have been the focus of numerous physics studies. This is because...
Engineering approach can improve stability of perovskite solar cells under reverse bias conditions
Solar cells based on perovskites, a versatile class of materials with promising optoelectronic properties, are gradually making their way toward commercialization. While these solar cells can have...
How fruit flies use internal representations of head direction to support goal-directed navigation
Animal behavior is known to rely on transforming sensory information into motor commands, often influenced by an animal's internal needs. While in mammals and other large animals this process is...
Study outlines an activity-regulated genetic program underlying the formation of synapses during development
Synapses are junctions via which neurons communicate with each other or with other types of cells. Synapses are formed throughout the course of a person's life, yet their strength and numbers change...
How hunger influences aversive learning in fruit flies
Internal states that animals experience while they are thirsty, hungry, sleepy or aggressive have been found to be linked with the combined activity of various neuromodulators and neurotransmitters....
Exploring the fundamental reasoning abilities of LLMs
Reasoning, the process through which human beings mentally process information to draw specific conclusions or solve problems, can be divided into two main categories. The first type of reasoning,...
Neuron populations in the medial prefrontal cortex shown to code the learning of avoidant behaviors
Over the course of their lives, animals form associations between sensory stimuli and predicted threats or rewards. These associations can, in turn, shape the behaviors of animals, prompting them to...
New Sisyphus cooling technique could enhance precision of atomic clocks
Researchers in the Neutral Atom Optical Clocks Group at the National Institute of Standards and Technology (NIST), University of Colorado and Pennsylvania State University recently devised a new...
