Cancer Disrupts the Brain’s Internal Clock

Breast cancer can rapidly derail the brain’s day-night regulation of stress hormones, even before tumors are detectable. In mice, the disease flattens normal corticosterone rhythms by altering hypothalamic neuron activity, which may worsen outcomes and mimic symptoms often seen in cancer patients, such as insomnia and anxiety.

Tiny Gut Imposters Could Be Driving Multiple Sclerosis

New research reveals that when gut bacteria closely resemble the myelin sheath that protects nerve fibers, the immune system can become confused and attack both — accelerating multiple sclerosis. In mouse experiments, bacteria engineered to mimic myelin triggered faster disease progression by activating aggressive immune cells that infiltrated the nervous system.

Blood Transfusions May Accelerate Alzheimer’s Progression

New research shows that blood from older animals can speed up Alzheimer’s-related changes in the brain, while young blood may slow them down. In a long-term experiment, mice engineered to develop Alzheimer’s symptoms received weekly blood infusions from either young or old donors.

AI Turns Simple EEG Scans Into Accurate Dementia Detectors

New research shows that deep learning can use EEG signals to distinguish Alzheimer’s disease from frontotemporal dementia with high accuracy. By analyzing both the timing and frequency of brain activity, the model uncovered distinct patterns: broader disruption across multiple regions in Alzheimer’s and more localized frontal and temporal changes in frontotemporal dementia.

Nicotine Withdrawal Makes Smokers More Sensitive to Pain

A new study shows that abstinent smokers experience heightened pain sensitivity linked to altered activity in specific brain regions. Compared to nonsmokers, abstinent smokers required more postoperative pain relief—especially opioids—and their pain sensitivity increased the longer they remained nicotine-free.

Blocking a Key Protein Greatly Reduces Alzheimer’s Damage

New findings show that removing Centaurin-α1, a protein elevated in Alzheimer’s disease, significantly reduces inflammation, plaque buildup, and cognitive deficits in a well-established mouse model. Eliminating this protein normalized several brain pathways, protected neural connections in the hippocampus, and improved spatial learning.

Microplastics Accelerate Alzheimer’s and Parkinson’s Damage

A new review highlights five major ways microplastics can harm the brain, raising concerns that they may worsen neurodegenerative diseases like Alzheimer’s and Parkinson’s. These tiny particles can trigger inflammation, disrupt the blood–brain barrier, generate oxidative stress, impair mitochondria, and damage neurons.

Mutation in Key Enzyme Triggers Ferroptosis and Childhood Dementia

Researchers have identified how a single mutation in the GPX4 enzyme causes neurons to undergo ferroptosis, leading to severe early-onset dementia. The study provides the first molecular evidence that ferroptosis can directly drive neurodegeneration in the human brain.

Fungal Molecule Shows Promise Against Brain Cancer

For the first time, chemists have fully synthesized verticillin A, a notoriously complex fungal molecule with striking anticancer potential. The molecule’s fragile structure required a complete rethinking of its synthetic sequence, enabling researchers to not only recreate it but design more stable and potent derivatives.

Obesity Speeds Alzheimer’s Biomarker by Up to 95 Percent

New longitudinal research shows that Alzheimer’s disease blood biomarkers rise up to 95 percent faster in people with obesity than in those without. While baseline tests initially appeared lower due to blood dilution, long-term tracking revealed a significantly accelerated buildup of neurodegeneration and amyloid pathology.

Shingles Vaccine Linked to 20% Lower Dementia Risk

A large population analysis found that older adults who received the shingles vaccine were significantly less likely to develop dementia over the following seven years. The study exploited a rare age-based rollout policy that closely mimicked a randomized trial, allowing researchers to isolate the vaccine’s true effect.

Scientists Achieve Sustained HIV Control Without Lifelong Drugs

Scientists tested a multi-step immune-based therapy designed to retrain the body to control HIV without continuous antiviral treatment. After stopping standard HIV drugs, seven out of ten participants maintained low viral levels for extended periods, and one showed no viral rebound at all.
