- newNew MRI breakthrough reveals the brain and eye like never before
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, and open the door to new medical imaging and treatment applications.

- newThis frog bacterium wiped out cancer tumors in mice with a single dose
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 therapy that could one day work against many solid tumors.

- newScientists found a longevity diet that helped mice eat more and lose fat
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 and Type 2 diabetes, suggesting the approach could benefit people as well.

- newScientists just debunked a dangerous baby rattlesnake myth
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 serious bites. The team also uncovered how the myth spread through decades of inaccurate news reports and misleading quotes from trusted sources.

- A hidden immune backup system could supercharge mRNA cancer vaccines
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 and help scientists tailor treatments for better patient outcomes.

- A vitamin A discovery is changing what scientists know about vision
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 the influence of vitamin A-related signals and thyroid hormones. The findings could improve lab-grown retinal tissue and lay the groundwork for future cell therapies to restore vision lost to age-related eye diseases.

- The Ozempic and Wegovy mistake sending thousands to poison control
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 proper weekly dosing and gradual dose increases could help prevent many of these avoidable incidents.

- Harvard scientists turn a silicon chip into a DNA writing machine
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 portable DNA-writing devices and even massive DNA data storage, although new chemistry will be needed to scale the technology further.

- Tiny silica particles wiped out aggressive prostate cancer in mice
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 mice, raising hopes for a powerful new approach to prostate cancer.

- Scientists finally crack nature's secret for building better cancer drugs
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 versions of existing medicines.

- Creatine doesn't just build muscle. It may also help fight cancer
Scientists have discovered that creatine may strengthen one of the immune system's most important cancer-fighting pathways by energizing dendritic cells that activate killer T cells. The promising results could eventually help make immunotherapy more effective, but they have not yet been tested in human patients.

- Can't stick to a diet? Intermittent fasting may be easier than counting calories for weight loss
Intermittent fasting helped people lose as much weight as calorie restriction, but without the same feeling of constantly controlling their food intake. Researchers say that difference could make fasting a more sustainable option for people who struggle with traditional diets.

- Scientists found a surprising cancer fighter hiding inside tumors
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.

- Takeaway meals contain more salt than advertised, study finds
Almost half of the takeaway meals tested contained more salt than advertised, with some dishes delivering nearly twice the recommended daily limit in a single serving. Surprisingly, classic fish and chips ranked among the lowest-salt options, while pasta, pizza, and curries were often the saltiest.

- New weight loss pill beats oral Ozempic in major trial
A new once-daily weight-loss pill called orforglipron delivered better weight loss and blood sugar improvements for people with type 2 diabetes than the leading oral semaglutide in a major clinical trial. The tablet could offer a more convenient alternative to injectable drugs like Ozempic and Wegovy because it doesn't require refrigeration or special timing with meals. It's also cheaper to manufacture, which could expand access globally.
