But new research in rats found the opposite: inflammation in a key decision-making brain region actually made behavior more deliberate, not more automatic. The change was linked to astrocytes, brain support cells that multiplied and disrupted nearby circuits. The discovery hints that some compulsive behaviors may arise from excessive, misdirected control rather than a loss of it. Mon, 16 Feb 2026 07:32:28 EST https://www.sciencedaily.com/releases/2026/02/260215225606.htm https://www.sciencedaily.com/releases/2026/02/260212234218.htm Scientists at Cedars-Sinai have uncovered a surprising repair system in the spinal cord that could open new doors for treating paralysis, stroke, and diseases like multiple sclerosis. They found that special support cells called astrocytes—located far from the actual injury—spring into action after damage. These “lesion-remote astrocytes” send out a protein signal, CCN1, that reprograms immune cells to efficiently clean up fatty nerve debris.

When OTULIN was disabled, tau vanished from neurons and brain cells remained healthy. The findings challenge long-held assumptions about tau’s necessity and highlight a promising new path for fighting Alzheimer’s and brain aging. Scientists now believe OTULIN may act as a master switch for inflammation and age-related brain decline.

It strengthens T-cells’ energy production, helping them fight cancer more effectively. By restoring fumarate levels or transplanting healthy mitochondria, researchers may be able to rejuvenate aging immune cells. These findings could inspire a new generation of treatments that target both cancer and age-related decline.

In a recent study, the drug lowered blood pressure and also seemed to protect the kidneys by reducing signs of damage. Doctors say this could help millions of people with chronic kidney disease, a condition that often makes blood pressure harder to control.

This newly discovered mechanism, visualized in real time with advanced microscopy, shows mitochondria acting like emergency first responders rather than static power plants. The structures, called NAMs, were also identified in patient tumor biopsies, suggesting real-world relevance to cancer’s spread.

In Parkinson’s disease models, reducing this regulator improved symptoms and mitochondrial health. The findings could inspire new drugs for Parkinson’s, mitochondrial disorders, and even cancer.

Astonishingly, the drugs only kill bacteria when they’re active, leaving dormant cells untouched. This discovery could explain recurring infections and inspire strategies to wake bacteria up before treatment.

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.

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.

Membrane changes in neurons send an “eat-me” signal to microglia, which mistakenly destroy them. Evidence from mice, human tissue, and PET scans confirms this process. These insights could pave the way for earlier diagnosis and more effective treatment.

Their decade-long research shows that lithium depletion—caused by amyloid plaques binding to it—triggers early brain changes that lead to memory loss. By testing new lithium compounds that evade plaque capture, they reversed Alzheimer’s-like damage and restored memory in mice at doses far lower than those used in psychiatric treatments.

Researchers discovered that these drugs not only fuel bacterial resistance on their own but make it far worse when combined with antibiotics. The findings are especially troubling for aged care settings, where residents commonly take multiple medications, creating perfect conditions for resistant bacteria to thrive.

While ketamine is frequently prescribed off-label for conditions like fibromyalgia and nerve pain, researchers found little convincing evidence of real benefit and flagged serious side effects such as delusions and nausea. The lack of data on whether it reduces depression or opioid use adds to the uncertainty.

By creating a novel tool to boost mitochondrial activity in mouse models, researchers restored memory performance, suggesting mitochondria could be a powerful new target for treatments. The findings not only shed light on the early drivers of brain cell degeneration but also open possibilities for slowing or even preventing diseases like Alzheimer’s.
