First Cognitive Decline may be uncovered by a house smell test.
Summary: A new study highlights that olfactory testing could offer a simple, cost-effective way to detect early cognitive impairment from home. Researchers found that older adults with mild cognitive issues performed worse on odor identification and memory tasks than cognitively normal individuals.The test, administered in English and Spanish, was equally

Why Just Putting Ahead Your PhoneWon’t Help You Focus
Summary: A new study reveals that placing your smartphone out of reach doesn’t significantly reduce distraction or boost productivity. While participants used their phones less when they were farther away, they simply shifted their attention to other devices like laptops. The core issue isn’t the phone itself but the deeply

Infomorphic Neurons Bring AI One Action Closer to Brain-Like Learning
Summary: Researchers have developed a new kind of artificial neuron—called infomorphic neurons—that can independently learn and self-organize with nearby neurons, mimicking the decentralized learning of biological brains. Inspired by pyramidal cells in the cerebral cortex, these neurons process local signals to adapt and specialize in tasks without external control.Each infomorphic

Men Ejaculation is based on the dopamine circuit in the brain that was discovered to push the serotonin circuit.
Summary: New research uncovers how dopamine in the ventral shell of the nucleus accumbens (vsNAc) governs the sexual behavior sequence in male mice, from sniffing to ejaculation. Using fiber photometry, scientists identified rhythmic dopamine activity during intromission that aligns with movement patterns and is regulated by acetylcholine inputs.Crucially, the final

Dopamine Surge Enhances the Brain’s Adaptational Skills
Summary: For the first time, researchers have directly observed dopamine release in the human brain during moments of cognitive flexibility. Using PET imaging, they found that dopamine levels spike in the ventromedial prefrontal cortex when people switch between tasks — and the more dopamine released, the more efficiently they adapted.This

Military ‘ mental health may be impacted by battle injuries, but this is not always the case.
Summary: A large study of over 14,000 Norwegian veterans reveals that taking a life in combat doesn’t automatically damage a soldier’s mental health—context matters. Veterans from Afghanistan, where combat was expected and rules of engagement were clear, showed no long-term psychological harm from killing.In contrast, Lebanon peacekeeping veterans who had
