Cambridge scientists created a gel that could end arthritis pain

Cambridge scientists have created a breakthrough material that can sense tiny chemical changes in the body, such as the increased acidity during an arthritis flare-up, and release drugs exactly when and where they’re needed. By mimicking cartilage while delivering medication, this smart gel could ease pain, reduce side effects, and provide continuous treatment for millions of arthritis sufferers.

Hidden bacterial molecules in the brain reveal new secrets of sleep

New studies show that a bacterial molecule, peptidoglycan, is present in the brain and fluctuates with sleep patterns. This challenges the idea that sleep is solely brain-driven, instead suggesting it’s a collaborative process between our bodies and microbiomes. The theory links microbes not only to sleep but also to cognition, appetite, and behavior, pointing to a profound evolutionary relationship.

Brain fat, not just plaques, may be the hidden driver of Alzheimer’s

For decades, scientists believed Alzheimer’s was driven mainly by sticky protein plaques and tangles in the brain. Now Purdue researchers have revealed a hidden culprit: fat. They found that brain immune cells can become clogged with fat, leaving them too weak to fight off disease. By clearing out this fat and restoring the cells’ defenses, researchers may have uncovered an entirely new way to combat Alzheimer’s — shifting the focus from plaques alone to how the brain handles fat.

AI-powered smart bandage heals wounds 25% faster

A new wearable device, a-Heal, combines AI, imaging, and bioelectronics to speed up wound recovery. It continuously monitors wounds, diagnoses healing stages, and applies personalized treatments like medicine or electric fields. Preclinical tests showed healing about 25% faster than standard care, highlighting potential for chronic wound therapy.

A tiny mineral may hold the secret to feeding billions sustainably

Rice, a staple for billions, is one of the most resource-hungry crops on the planet—but scientists may have found a way to change that. By applying nanoscale selenium directly to rice plants, researchers dramatically improved nitrogen efficiency, boosted yields, and made grains more nutritious while reducing fertilizer use and cutting greenhouse gas emissions.

Tylenol in pregnancy linked to higher autism risk, Harvard scientists report

Researchers reviewing 46 studies found evidence linking prenatal acetaminophen (Tylenol) exposure with higher risks of autism and ADHD. The FDA has since urged caution, echoing scientists’ advice that the drug be used only at the lowest effective dose and shortest duration. While important for managing fever and pain in pregnancy, prolonged use may pose risks to fetal development. Experts stress careful medical oversight and further investigation.

Dementia-like clumps found in cells before cancer strikes

Researchers found that pancreatic pre-cancer cells mimic dementia by forming clumps of proteins due to faulty recycling processes. These insights could shed light on why pancreatic cancer develops so aggressively and why it is difficult to treat. By studying overlaps with neurological diseases, scientists hope to identify new strategies for prevention and treatment.

Hidden brain signal reveals Alzheimer’s years before symptoms

A new study has revealed that TSPO, a protein linked to brain inflammation, rises long before Alzheimer’s symptoms appear. Researchers tracked the protein in genetically engineered mice and confirmed the results in human brain tissue from Colombian families with a known Alzheimer’s mutation. They found unusually high levels of TSPO in microglia clustered around plaques, particularly in women. This discovery not only deepens our understanding of the disease but also sparks the possibility of using TSPO to detect and treat Alzheimer’s far earlier than ever before.

A hormone that silences the immune system may unlock new cancer treatments

Scientists have discovered that cancer uses a hidden hormone to switch off the body’s natural defenses, allowing tumors to grow unchecked. By uncovering this secret signal, they found a way to block it and restore the immune system’s ability to fight back. The breakthrough not only hints at powerful new cancer treatments but also suggests the same pathway could someday be used to calm autoimmune diseases.
