Tumors appear to recruit macrophages—immune cells normally involved in healing and fighting infection—and use them to release a protein called BDNF that draws nerves into the tumor. Those nerves may then help the cancer grow, resist treatment, and potentially spread. Mon, 17 Aug 2026 08:06:50 EDT https://www.sciencedaily.com/releases/2026/08/260814011038.htm https://www.sciencedaily.com/releases/2026/08/260814011033.htm Scientists have discovered that the aging human brain may be far less isolated from the rest of the body than once believed. Stanford researchers found that large numbers of immune cells from the blood begin entering the brain as early as middle age, where they can transform into microglia, the brain’s specialized immune cells. The finding overturns a long-standing assumption that these cells remain largely separate from the body’s immune system throughout life. Fri, 14 Aug 2026 09:28:02 EDT https://www.sciencedaily.com/releases/2026/08/260814011033.htm https://www.sciencedaily.com/releases/2026/08/260812015158.htm The adult brain may be far better at repairing itself than scientists once believed. In mice, researchers discovered a special group of support cells called astrocytes that respond to damaged brain tissue by rebuilding lost cellular networks. Rather than simply moving into the injured area, these cells perform a remarkable maneuver: they create new nuclei and send them traveling through long cellular extensions to repopulate damaged regions. Wed, 12 Aug 2026 08:43:16 EDT https://www.sciencedaily.com/releases/2026/08/260812015158.htm https://www.sciencedaily.com/releases/2026/08/260811011138.htm Ozempic-like drugs appear to weaken more than hunger—they may also reduce cravings for alcohol and other addictive substances. Scientists are increasingly tracing this effect to the lateral septum, a brain region that helps connect memories and surroundings with rewarding experiences. Packed with GLP-1 receptors, it may act as a crucial control point between thinking about a reward and feeling compelled to pursue it. The discovery could open new approaches to treating addiction as well as obesity.

Instead of creating an entirely new drug, researchers paired vancomycin with a small molecule called pghi-4, which blocks a bacterial enzyme linked to resistance. The combination restored the antibiotic’s ability to kill drug-resistant E. faecium, raising hopes that similar chemical helpers could rescue other failing medicines. Wed, 22 Jul 2026 03:21:08 EDT https://www.sciencedaily.com/releases/2026/07/260722032108.htm https://www.sciencedaily.com/releases/2026/07/260719040002.htm The mysterious sound known as The Hum has been reported worldwide for decades, yet its source often remains impossible to find. Researchers tested whether people who hear it have exceptional low-frequency hearing or measurable sounds produced inside their ears, but neither explanation fit most participants. The strongest possibility is that many cases involve low-frequency tinnitus, even though the sound seems completely external. Sun, 19 Jul 2026 08:07:13 EDT https://www.sciencedaily.com/releases/2026/07/260719040002.htm https://www.sciencedaily.com/releases/2026/07/260719035931.htm Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep. Temporarily removing most of these cells restored more than two hours of sleep per day, even though the plaques remained unchanged. Mon, 20 Jul 2026 06:05:34 EDT https://www.sciencedaily.com/releases/2026/07/260719035931.htm https://www.sciencedaily.com/releases/2026/07/260716023605.htm The Mediterranean diet may influence aging through tiny proteins produced inside the cell’s mitochondria. Older adults who followed the diet most closely had higher levels of humanin and SHMOOSE, which have been linked to heart and brain protection. Olive oil, fish, legumes, and fewer refined carbohydrates appeared especially important. The findings could eventually help scientists develop more personalized nutrition plans for healthy aging. Fri, 17 Jul 2026 22:24:14 EDT https://www.sciencedaily.com/releases/2026/07/260716023605.htm https://www.sciencedaily.com/releases/2026/07/260708022202.htm Scientists have created a silicon chip that can write dozens of DNA sequences simultaneously using electricity and water-based enzymes, offering a cleaner alternative to conventional DNA manufacturing.

Researchers found that disabling it in human cells boosts fat burning, increases energy use, and makes it harder for new fat cells to develop. The findings help explain why mice lacking Mitch were leaner, more athletic, and resistant to obesity. Thu, 02 Jul 2026 20:22:49 EDT https://www.sciencedaily.com/releases/2026/06/260624115324.htm https://www.sciencedaily.com/releases/2026/06/260623083119.htm Scientists at the University of Illinois Chicago have turned an unlikely source into a potential new weapon against cancer: bacteria that naturally live inside tumors. They developed a peptide called aurB, inspired by a bacterial protein, that infiltrates cancer cells and effectively cuts off their energy supply by targeting the mitochondria—the cells’ power plants. Tue, 07 Jul 2026 16:23:00 EDT https://www.sciencedaily.com/releases/2026/06/260623083119.htm https://www.sciencedaily.com/releases/2026/06/260623083116.htm Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy. The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago. Today, researchers are finding that B12 may also help keep cellular powerhouses called mitochondria functioning properly. This could explain why some people experience fatigue and brain fog even before traditional signs of deficiency show up. Thu, 25 Jun 2026 10:57:39 EDT https://www.sciencedaily.com/releases/2026/06/260623083116.htm https://www.sciencedaily.com/releases/2026/06/260621060307.htm Scientists have uncovered a surprising clue that may help explain why multiple sclerosis (MS) progresses rapidly in some people but not others. In brain tissue from patients with severe MS, researchers found large numbers of “foamy” immune cells packed with fat droplets after absorbing damaged myelin. These overloaded cells appear to switch from helping repair the brain to fueling ongoing damage and inflammation.

The culprit is a toxic pairing of two proteins that, when combined, triggers the destruction of brain cells and fuels memory loss. By using a new compound to break apart this deadly duo, researchers were able to slow disease progression, protect brain cells, and even reduce hallmark amyloid buildup.

This area, which kicks in during forceful exhalations like coughing, laughing, or exercise, also appears to activate nerves that tighten blood vessels—raising blood pressure. When researchers switched off this region in experiments, blood pressure dropped back to normal, suggesting it plays a direct role in hypertension.

Researchers discovered that lecanemab works by activating the brain’s immune cells—but only through a specific part of the antibody called the Fc fragment. This piece acts like a trigger, prompting microglia to clear harmful amyloid plaques. The finding could reshape how future Alzheimer’s therapies are designed.

Researchers found that TDP43 controls a key DNA repair process, but when the protein becomes imbalanced, the repair system can spiral out of control, harming neurons and destabilizing DNA. The team also discovered that high levels of the protein are linked to increased mutation rates in cancer. The discovery places TDP43 at the center of both neurodegeneration and cancer biology.

Scientists discovered that most of it resides inside mitochondria, yet how it reached these cellular powerhouses was unclear. Yale researchers have now identified the transport system that moves CoA into mitochondria, solving a long-standing biological puzzle. The discovery could help researchers better understand diseases linked to metabolic dysfunction and mitochondrial problems.

In mouse studies, researchers found that even a very small dose of EVG7 was highly effective at clearing the infection and preventing it from coming back. Unlike many current antibiotics, which wipe out large portions of the gut microbiome, EVG7 appears to spare beneficial bacteria that naturally help keep C. difficile in check.

Patients taking higher doses experienced up to 47% fewer pauses in breathing and improved oxygen levels during sleep. The drug helps stabilize breathing signals in the brain, reducing airway collapse. Scientists say the findings could pave the way for a pill-based alternative to CPAP machines.

Researchers found that people who eat more fruits and vegetables known to carry higher pesticide residues—such as strawberries, spinach, and bell peppers—also have significantly higher levels of those chemicals in their urine. While produce remains a cornerstone of a healthy diet, the findings highlight how everyday food choices can drive real-world exposure to substances linked to cancer, hormone disruption, and developmental harm.
