New Alzheimer's drug repairs DNA damage and reduces brain inflammation

A drug originally developed for spinal cord injury may offer a fresh approach to treating Alzheimer’s disease. In mouse studies, KCL-286 repaired dangerous DNA damage, reduced inflammation, and targeted multiple disease-related pathways instead of focusing on just amyloid or tau. Since it has already cleared an initial human safety trial, researchers believe it could move more quickly into Alzheimer’s clinical testing.

This pet gecko could help scientists unlock the secrets of cancer

An unusual leopard gecko that naturally develops aggressive tumors may become an important new model for cancer research. Scientists found its tumors share key genetic changes with human cancers, offering a rare opportunity to study the disease as it develops naturally.

Chewing bubble gum after beetroot may help lower blood pressure

A new study found that chewing sugary gum after eating nitrate-rich vegetables or drinking beetroot juice helped the body produce more beneficial nitrite, leading to a temporary drop in blood pressure. Researchers hope the discovery will lead to healthier ways to enhance the cardiovascular and performance benefits of dietary nitrate without relying on sugar.

Popular weight-loss drugs Ozempic and Wegovy may slow biological aging

Researchers found that semaglutide, the active ingredient in Ozempic and Wegovy, slowed biological aging markers in adults with HIV, marking the first clinical evidence that the drug may influence human aging. Although the findings are encouraging, scientists say larger studies are needed before concluding that the medication can help people age more slowly.

Scientists discover why peach fuzz can suddenly make you itch

A newly discovered network of fine hairs and specialized nerve cells appears to form a dedicated system for sensing mechanical itch, offering fresh insight into why chronic itching occurs. Because humans show signs of having the same pathway, the research could pave the way for more effective treatments for conditions such as eczema.

Scientists discovered the brain doesn't make decisions the way we thought

A new study suggests the brain begins making decisions much earlier than scientists previously thought. Researchers found that even primary sensory regions are influenced by higher brain areas through rapid feedback loops, rather than simply passing information forward. This more dynamic view of brain function could help engineers design future AI systems that think more like biological brains while using far less power.

Scientists discover a hidden heart valve risk linked to gum disease

Researchers found that bacteria linked to gum disease may help drive the development of calcific aortic valve stenosis by triggering inflammation and calcium buildup in the heart valve. The early findings suggest that keeping gums healthy could play a role in reducing the risk of this serious heart condition.

This ultrasound treatment may help stop arthritis before it starts

A simple, non-invasive ultrasound treatment could one day help injured joints heal instead of remaining trapped in a cycle of damaging inflammation. Researchers at The University of Alabama in Huntsville found that continuous low-intensity ultrasound encouraged key immune cells called macrophages to shift from an inflammatory state toward one that supports tissue repair.

Scientists discover the one nutrient beneficial parasites can't live without

A new study found that dietary fiber can determine whether beneficial intestinal worms help reduce inflammation or become essentially inactive. With plenty of fiber, the worms remained healthy and supported an anti-inflammatory response, while a low-fiber diet pushed them into a hibernation-like state that eliminated those benefits. Researchers also found that fiber-rich diets promoted healthier gut bacteria, whereas Western-style diets reduced microbial diversity and encouraged less desirable microbes.

New MRI breakthrough reveals the brain and eye like never before

Scientists have redesigned a key piece of MRI hardware using metamaterials, allowing existing scanners to produce clearer images of difficult-to-see parts of the body in less time. The breakthrough could improve diagnoses, make scans more comfortable, and open the door to new medical imaging and treatment applications.
