Scientists Trick Neurons Into Thinking They’re Inside a Living Brain

Neuroscience /

Neurons, the brain’s essential cells, form intricate networks by exchanging signals, enabling learning and adaptation. Researchers at Delft University of Technology (TU Delft) in the Netherlands have created a 3D-printed environment that closely resembles real brain tissue. Using nanoscale pillars, they replicate the soft, fibrous structure that supports neurons. This innovation provides a more accurate […]

Oral Microbes Could Influence Your Risk of Cognitive Decline

Microbiology, Uncategorized /

The bacteria in your mouth affect more than just your teeth and gums—they may also play a role in brain function. A study of 55 people with mild cognitive impairment (MCI) found that those with higher levels of Neisseria bacteria performed better on tests of working memory, executive function, and visual attention. Even among 60

How Bacteria Detect Nearby Death and Gear Up for Combat

Microbiology /

Researchers at the University of Basel have uncovered how bacteria sense environmental threats using a universal danger signal. When nearby cells are dying, bacteria detect fragments of their cell walls, called peptidoglycans, and proactively form protective biofilms. This discovery sheds light on bacterial communication and defense mechanisms, offering insights for combating infections. Sensing Danger: The

Microscopic Fossilized Embryos Unveil Fascinating Insights into Life 500 Million Years Ago

Microbiology, Science /

Tiny mineralized spheres are offering fresh insights into the history of life on Earth. These millimeter-sized fossils, over 535 million years old, are the fossilized embryos of early Cambrian animals. Belonging to the Ecdysozoa group—which includes insects, spiders, crustaceans, and worms—the embryos present a fascinating mystery. While researchers cannot definitively identify their adult forms, Mingjin

Expert Identifies Irregular Brain Wave Patterns as Potential Indicator of ADHD

Neuroscience /

Children with attention deficit hyperactivity disorder (ADHD) are not lazy, undisciplined, or lacking manners. Instead, their brains develop and function differently, marked by unique neurological activity patterns and neurochemical imbalances. These differences classify ADHD as a neurodevelopmental disorder rather than a behavioral issue. The Neurological Basis of ADHD The neurological variations in ADHD manifest as

Adults Generate New Brain Cells, Which Play a Role in Enhancing Learning Through Listening

Neuroscience, Science /

Your brain can still produce new neurons in adulthood, but how do these rare additions support cognitive function? Neurons, the cells responsible for brain function, are mostly formed before birth. While early life sees the bulk of brain development, certain regions continue generating neurons into adulthood, albeit at a slower pace. Scientists debate whether adult
