Experts say high blood pressure guidelines are missing half the equation

15:06
Scientists are calling for a major rethink of how we manage high blood pressure, suggesting that eating more potassium could be just as important as cutting back on salt. A new report finds that combining increased potassium intake with reduced sodium consumption may offer greater benefits for blood pressure control than sodium reduction alone.

NASA reveals a haunting skull hidden in Antarctica’s ice

15:06
NASA satellites have captured an eerie, skull-shaped formation on a remote Antarctic island, but its haunting appearance conceals a troubling warning about melting glaciers. Unusually warm winter temperatures have exposed large areas of dark ice, potentially accelerating future melting and gradually transforming the skull's ghostly features.

NASA’s Perseverance Mars rover breaks historic record after traveling 28 miles

15:06
NASA’s Perseverance rover has set a historic record by traveling 28.10 miles across Mars, farther than any vehicle has ever driven on another world. Armed with groundbreaking autonomous navigation technology and increasingly advanced driving capabilities, the rover is pushing the boundaries of robotic exploration.

IceCube detects ghost particles with 10 billion times the energy of solar neutrinos

15:06
Mysterious particles called neutrinos constantly stream through our bodies, and scientists are now detecting incredibly powerful versions arriving from distant cosmic sources using a massive observatory buried in Antarctic ice. These elusive “ghost particles” could hold extraordinary clues about the Big Bang, extreme cosmic events, and some of the universe’s greatest mysteries.

NASA's Hubble and Webb discover ancient worlds that remember their past

15:06
NASA’s Hubble and James Webb Space Telescopes have uncovered surprising clues about the solar system’s origins by studying 27 tiny, distant objects beyond Neptune. Scientists discovered that these ancient building blocks of planets have remained remarkably unchanged for billions of years, while their unexpected sizes and numbers challenge existing theories of planet formation.

Even moderate drinking linked to cancer and early death, major study finds

15:06
A major new study challenges the idea that moderate drinking is safe, finding that even relatively small amounts of alcohol increase the risk of cancer, heart disease, and premature death. Researchers found no overall health benefits from drinking and warn that consuming more than one alcoholic beverage per day can significantly increase long-term health risks.

Scientists find surprisingly little evidence that medical cannabis helps you sleep

15:06
A major new review challenges the growing enthusiasm for medical cannabis as an insomnia treatment, finding little reliable evidence that it improves sleep quality, sleep duration, or daytime functioning. Researchers caution that this doesn't mean cannabis is ineffective, only that existing studies are too weak to establish whether it works.

30,000-year-old DNA reveals Ice Age Europeans were far more connected than we thought

15:06
Scientists have uncovered surprising DNA evidence that Europeans living more than 30,000 years ago were connected across vast distances, challenging the idea that ancient populations remained largely isolated. Genetic clues from human remains and cave sediments reveal prehistoric migration, long-lasting communities, and survival through the harshest conditions of the Ice Age.

New diabetes implant uses electricity to lower blood sugar and promote weight loss

15:06
Researchers have developed a remarkable new electronic implant that could transform type 2 diabetes treatment by lowering blood sugar without insulin or traditional drugs. The device uses a special electrically powered catalyst to convert excess glucose into a substance that the body eliminates through urine, potentially preventing unwanted energy from being stored as fat. In diabetic mice, the i…

Scientists discover that some “unhealthy” diets can boost cancer immunotherapy in mice

15:06
In a surprising discovery, scientists found that certain diets associated with obesity can make cancer immunotherapy more effective in mice, challenging traditional assumptions about diet and cancer treatment. The findings suggest that the secret may lie in how food interacts with gut bacteria to strengthen the immune system's response to cancer.

Drinking tea may help protect your heart, but there’s a surprising catch

1.listopadu
A massive study of nearly 486,000 adults found that regularly drinking tea was associated with an 11% lower risk of heart and blood vessel diseases. The lowest risk was linked to drinking roughly six to eight cups per day, with black tea showing more consistent benefits than green tea.

Common pesticide linked to 2.5 times the risk of Parkinson’s disease

1.listopadu
A UCLA study found that long-term exposure to a common pesticide was linked to more than 2.5 times the risk of Parkinson's disease. Scientists also uncovered how the chemical damages brain cells and identified a promising way to protect them.

Ancient ape fossil in Egypt could rewrite the story of human origins

1.listopadu
A 17- to 18-million-year-old ape fossil discovered in Egypt is challenging long-held beliefs about where the ancestors of humans and other modern apes first evolved. Scientists now suspect that North Africa and the Middle East, rather than East Africa, may have been the cradle of modern ape evolution.

Scientists use sound waves to deliver a new attack on deadly brain cancer

1.listopadu
Scientists at the University of Virginia have developed a promising new strategy to fight glioblastoma, one of the deadliest and most difficult-to-treat forms of brain cancer. Their experimental approach combines focused ultrasound, tiny nanoparticles, and genetic molecules called microRNAs to attack multiple cancer-driving genes simultaneously.

Scientists discover a surprising brain benefit of eating peanuts every day

1.listopadu
A surprising new study suggests that eating peanuts every day could help support brain health and memory in older adults. Researchers found that consuming about two servings of unsalted, skin-roasted peanuts daily for 16 weeks improved insulin responsiveness in brain regions important for memory, a function that often weakens with age and has been linked to Alzheimer's disease.
