This diet could slash cholera infections by up to 100x

A surprising new study reveals that what you eat could play a powerful role in fighting cholera, a deadly diarrheal disease. Researchers found that diets rich in certain proteins—especially casein from dairy and wheat gluten—can dramatically reduce the ability of cholera bacteria to take hold in the gut, in some cases cutting infection levels by up to 100 times. These proteins appear to disable a key “weapon” the bacteria use to attack other microbes and dominate the gut environment.

A drug already in trials may finally stop hepatitis E

Scientists have identified a potential new weapon against hepatitis E, a virus with no approved treatment and tens of thousands of deaths each year. The drug bemnifosbuvir, currently in trials for hepatitis C, was found to block the virus from replicating by disrupting its genetic machinery. Tests in cells and animals showed strong effectiveness without harming healthy tissue. If ongoing trials succeed, the drug could soon be repurposed for hepatitis E.

Scientists find hidden brain cells helping deadly cancer grow

Scientists in Canada have uncovered a surprising weakness in glioblastoma, one of the deadliest brain cancers. They found that certain brain cells—once believed to only support healthy nerves—can actually help tumors grow by sending signals that strengthen cancer cells. When researchers blocked this communication, tumor growth slowed dramatically in lab models.

Scientists found a protein that drives brain aging — and how to stop it

Scientists have uncovered a powerful new clue in the mystery of brain aging: a single protein called FTL1. In aging mice, higher levels of this protein weakened connections between brain cells and led to memory decline. But when researchers reduced FTL1, something remarkable happened — the brain began to recover, rebuilding lost connections and restoring memory performance.

Scientists create “smart” DNA drug that targets cancer cells with extreme precision

Scientists have created a programmable drug system that can zero in on cancer cells with unprecedented accuracy. Built from synthetic DNA, it only activates when it detects a precise combination of tumor markers, preventing damage to healthy tissue. The system can also deliver multiple drugs at once, potentially overcoming resistance. This marks a step toward medicines that behave more like smart, responsive machines inside the body.

A gene mutation may trap the brain in the wrong reality in schizophrenia patients

A newly identified gene mutation may help explain why schizophrenia patients struggle to update their understanding of reality. The mutation disrupts a brain circuit involved in flexible decision-making, causing mice to stick with outdated choices even when conditions change. Researchers pinpointed the issue to a key thalamus–prefrontal cortex pathway. By reactivating this circuit, they were able to restore normal behavior—raising hope for future therapies.

Breakthrough could protect the vision cells that let you see faces and colors

Scientists have taken a major step toward protecting the very cells that make sharp, colorful vision possible. By testing more than 2,700 compounds in thousands of lab-grown human retinal models, researchers uncovered several molecules that can shield cone photoreceptors—the cells responsible for reading, recognizing faces, and seeing color—from degeneration. They also identified a key protective mechanism involving casein kinase 1, offering a promising new target for treatment.

Scientists discover “molecular shredder” that helps deadly parasite evade the immune system

A deadly parasite responsible for sleeping sickness has been found using a surprisingly precise trick to stay hidden in the human bloodstream. Scientists discovered a protein called ESB2 that acts like a “molecular shredder,” cutting up specific genetic instructions as they are produced. This allows the parasite to flood its surface with protective proteins while suppressing other signals that might give it away.

This simple Japanese eating habit could help you live longer without dieting

Hara hachi bu, a traditional Japanese practice of eating until you’re about 80% full, is gaining attention as a simple yet powerful way to improve health and reshape our relationship with food. Rather than promoting strict dieting, it encourages slowing down, tuning into hunger cues, and eating with awareness and gratitude. Research suggests it may help reduce calorie intake, support healthier food choices, and prevent long-term weight gain.

Eating more meat may lower Alzheimer’s risk for some people

A surprising new study suggests that genetics may change how diet affects brain health—especially when it comes to Alzheimer’s risk. Researchers found that older adults carrying high-risk APOE gene variants didn’t show the expected cognitive decline if they ate relatively high amounts of meat. In fact, those with these genes who consumed the most meat had slower cognitive decline and lower dementia risk, challenging conventional dietary advice.
