A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation and starving brain tissue. When the missing ...

Alzheimer's has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain's energy supply help drive the disease--and restoring that balance can reverse damage, even in ...

The familiar fight between "mind as software" and "mind as biology" may be a false choice. This work proposes biological computationalism: the idea that brains compute, but not in the abstract, symbol-shuffling way we usually imagine. Instead, ...

A four-amino acid peptide called CAQK has shown powerful brain-protective effects in animal models of traumatic brain injury. Delivered through a standard IV, it zeroes in on injured brain tissue, calming inflammation and reducing cell death while .. ...

Researchers have created tiny metal-based particles that push cancer cells over the edge while leaving healthy cells mostly unharmed. The particles work by increasing internal stress in cancer cells until they trigger their own shutdown process. In . ...

Scientists studying thousands of rats discovered that gut bacteria are shaped by both personal genetics and the genetics of social partners. Some genes promote certain microbes that can spread between individuals living together. When researchers ...

Scientists at MIT and Stanford have unveiled a promising new way to help the immune system recognize and attack cancer cells more effectively. Their strategy targets a hidden "off switch" that tumors use to stay invisible to immune defenses--special ...

A deadly hospital fungus that resists nearly every antifungal drug may have an unexpected weakness. Researchers discovered that Candida auris activates specific genes during infection to hunt for nutrients it needs to survive. This insight came from ...

A new imaging technology can distinguish cancerous tissue from healthy cells by detecting ultra-weak light signals. It relies on nanoparticles that bind to tumor markers, making cancerous areas easier to identify. The system is far more sensitive ...

When we watch someone move, get injured, or express emotion, our brain doesn't just see it--it partially feels it. Researchers found eight body-like maps in the visual cortex that organize what we see in the same way the brain organizes touch. These ...
