This new 3D chip could break AI’s biggest bottleneck
Researchers have created a new kind of 3D computer chip that stacks memory and computing elements vertically, dramatically speeding up how data moves inside the chip. Unlike traditional flat designs, this approach avoids the traffic jams that limit today’s AI hardware. The
This tiny peptide could help stop brain damage after injury
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 improving recovery. The
These nanoparticles kill cancer cells while sparing healthy ones
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 lab tests, they killed cancer
Your roommate’s genes may be shaping your gut bacteria
