Scientists have redesigned a key piece of MRI hardware using metamaterials, allowing existing scanners to produce clearer images of difficult-to-see parts of the body in less time. The breakthrough could improve diagnoses, make scans more comfortable ...

A naturally occurring bacterium from amphibian intestines completely eliminated colorectal tumors in mice with a single treatment by both attacking cancer cells and activating the immune system. The findings point to a promising new type of cancer .. ...

Scientists found that a modified Mediterranean-style diet with low protein and just enough methionine helped mice live healthier lives while reducing body fat and frailty. Human data also linked lower animal protein intake to lower rates of obesity . ...

A new study debunks the long-standing claim that baby rattlesnakes are more dangerous than adults. Researchers found that young rattlesnakes can control their venom just like adults, while adult snakes usually inject much more venom and cause more .. ...

Researchers found that mRNA cancer vaccines can recruit an unexpected immune cell to launch powerful tumor-fighting responses, overturning a long-held assumption about how the vaccines work. The discovery could lead to more effective cancer vaccines ...

A surprising discovery is reshaping scientists' understanding of how humans develop sharp central vision before birth. Instead of blue cone cells migrating away from the retina's center, the study found they transform into red and green cones under . ...

Poison control calls involving semaglutide (Ozempic and Wegovy) soared after the drug was approved for weight management, with researchers linking the increase to accidental dosing mistakes rather than intentional misuse. Simple education about ...

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. The breakthrough could eventually support ...

Tiny silica nanoparticles engineered to seek out prostate cancer caused tumor cells to self-destruct and supercharged the immune system in preclinical mouse studies. Combined with immunotherapy, the treatment produced complete remissions in multiple ...

Researchers have cracked the code behind bacteria's ability to naturally manufacture multiple versions of powerful anti-cancer drugs. The discovery could make it much easier to engineer new cancer treatments inspired by nature, including improved ...
