Scientists discover a hidden force that helps wire the brain
Growing neurons rely on chemical cues to find their targets, but new research shows that the brain’s physical properties help shape those signals. Scientists discovered that tissue stiffness can trigger the production of guidance molecules through a force-sensing protein called Piezo1. This protein not only detects mechanical forces but also helps maintain the structure of brain tissue. The discovery reveals a powerful link between the brain’s physical environment and how its wiring is built.

Scientists build a “periodic table” for AI
Choosing the right method for multimodal AI—systems that combine text, images, and more—has long been trial and error. Emory physicists created a unifying mathematical framework that shows many AI techniques rely on the same core idea: compress data while preserving what’s most predictive. Their “control knob” approach helps researchers design better algorithms, use less data, and avoid wasted computing power. The team believes it could pave the way for more accurate, efficient, and environmentally friendly AI.

Simple blood test can forecast Alzheimer’s years before memory loss
Scientists have created a blood test that can estimate when Alzheimer’s symptoms are likely to begin. By measuring a protein called p-tau217, the model predicts symptom onset within roughly three to four years. The protein mirrors the silent buildup of amyloid and tau in the brain long before memory loss appears. This advance could speed up preventive drug trials and eventually guide personalized care.

Common pneumonia bacterium may fuel Alzheimer’s disease
A common bacterium best known for causing pneumonia and sinus infections may also play a surprising role in Alzheimer’s disease. Researchers found that Chlamydia pneumoniae can invade the retina and brain, where it sparks inflammation, nerve cell death, and the buildup of amyloid-beta—the hallmark protein linked to Alzheimer’s. Higher levels of the bacterium were found in people with Alzheimer’s, especially those carrying the high-risk APOE4 gene, and were tied to more severe cognitive decline.

Scientists reveal how exercise protects the brain from Alzheimer’s
Exercise may sharpen the mind by repairing the brain’s protective shield. Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein causing the blood-brain barrier to become leaky with age. In older mice, dialing down this protein reduced inflammation and improved memory. The discovery points to a surprising body-to-brain pathway that could inspire new Alzheimer’s therapies.
Doctors implant dopamine-producing stem cells in Parkinson’s patients
A groundbreaking clinical trial is testing whether specially engineered stem cells can help the brain restore its own dopamine production in people with Parkinson’s disease. Because the condition is driven by the gradual loss of dopamine-producing cells—leading to tremors, stiffness, and slowed movement—researchers are implanting lab-grown cells directly into the brain’s movement center to replace what’s been lost.

Why scientists played make-believe with an ape : Short Wave
Picture this: You’re at a pretend tea party, but instead of sitting across from toddlers in tiaras, you’re clinking cups with Kanzi—an ape with the incredible ability to communicate with humans. NPR science correspondent Nate Rott talked to some scientists who did exactly that. But these scientists weren’t just having pretend tea parties with Kanzi for fun, they were trying to test the limits of his imagination – because humans’ ability to play out “pretend” scenarios in our heads and guess at the potential consequences of our actions is key to how we live our lives. And we might not be the only animals to do it!For more of Nate’s reporting, plus videos of Kanzi, check out the full story on NPR here.

Testimonials about the beneficial health effects of magnesium supplements abound online, with influencers claiming that a daily pill can help with everything from anxiety to sleep and brain fog. But do any of these claims stack up?
Scientists discover brain switches that clear Alzheimer’s plaques
Researchers have identified two brain receptors that help the brain clear away amyloid beta, a hallmark of Alzheimer’s disease. By stimulating these receptors in mice, scientists increased levels of a natural amyloid-breaking enzyme, reduced buildup in the brain, and improved memory-related behavior. Because these receptors are common drug targets, the findings could open the door to affordable pill-based treatments with fewer side effects.
Here’s how even occasional binge drinking can have big health consequences
Americans are drinking less than they have in decades. But a new study on mice shows even one bottomless brunch may shrink the small intestine’s nutrient-absorbing surface and spark inflammation that reaches the brain.

One in three people carry this brain parasite but the body has a kill switch
A parasite that may already be hiding in your brain has a shocking survival trick: it can infect the very immune cells sent to destroy it. Yet most people never get sick, and new research from UVA Health reveals why. Scientists discovered that when Toxoplasma gondii invades CD8+ T cells — key defenders of the immune system — those cells can trigger a self-destruct mechanism powered by an enzyme called caspase-8. By sacrificing themselves, the infected cells also wipe out the parasite inside them.

Why some kids struggle with math even when they try hard
A new Stanford study suggests math struggles may be about more than numbers. Children who had difficulty with math were less likely to adjust their thinking after making mistakes during number comparison tasks. Brain imaging showed weaker activity in regions that help monitor errors and guide behavioral changes. These brain patterns could predict which children were more likely to struggle.
Scientists found a way to plant ideas in dreams to boost creativity
Sleeping on a problem might be more powerful than we ever imagined. Neuroscientists at Northwestern University have shown that dreams can actually be nudged in specific directions — and those dream tweaks may boost creativity. By playing subtle sound cues during REM sleep, researchers prompted people to dream about unsolved brain teasers they had struggled with earlier. An astonishing 75% of participants dreamed about the cued puzzles, and those puzzles were solved far more often the next day.
Psychedelics may work by shutting down reality and unlocking memory
Psychedelics can quiet the brain’s visual input system, pushing it to replace missing details with vivid fragments from memory. Scientists found that slow, rhythmic brain waves help shift perception away from the outside world and toward internal recall — almost like dreaming while awake. By imaging glowing brain cells in mice, researchers watched this process unfold in real time.
