The best strength training plan might be simpler than you think

13:32
New strength training guidelines emphasize that doing any resistance training is what truly matters. Based on decades of research, experts say even simple routines can increase muscle, strength, and physical function. The key is not perfection but consistency. In fact, the best workout plan is the one you can maintain long term.

Physicists discover a heavy cousin of the proton at CERN’s Large Hadron Collider

13:32
A new subatomic particle known as the Ξcc⁺ has been discovered at CERN’s Large Hadron Collider. This heavy proton-like particle contains two charm quarks and was detected using the upgraded LHCb experiment. Scientists observed it through its decay into lighter particles in high-energy collisions. The finding confirms predictions and settles a decades-long question about its existence.

Scientists discover tiny rocket engines inside malaria parasites

13:32
Malaria parasites contain tiny spinning crystals that have puzzled scientists for years. New research reveals they’re powered by a rocket-like reaction that breaks down hydrogen peroxide, releasing energy. This motion may help the parasite detoxify harmful chemicals and manage iron more efficiently. The discovery could lead to new drugs and spark innovations in microscopic robotics.

Cutting sweet foods doesn’t reduce cravings or improve health

13:32
A new study suggests that eating less sweet food doesn’t make people crave it any less—or improve their health markers. Participants who increased or decreased sweetness in their diets showed no changes in preferences, weight, or disease risk. Many even returned to their old eating habits over time. Researchers say it may be time to rethink guidelines that focus on cutting sweetness instead of re…

Wildfires in carbon-rich tropical peatlands hit 2000-year high

7:39
Tropical peatlands, some of the planet’s largest underground carbon stores, are now burning at levels never seen in at least 2,000 years. By analyzing charcoal preserved in peat across multiple continents, scientists discovered that fires had actually been declining for more than a thousand years, largely shaped by natural climate patterns like drought. That long trend suddenly reversed in the 20…

Scientists recreated a dinosaur nest to solve a 70-million-year-old mystery

7:39
Scientists recreated a life-size oviraptor nest to understand how these dinosaurs hatched their eggs. Their experiments showed the parent likely couldn’t heat all the eggs directly, meaning sunlight played a key role. This uneven heating could cause eggs in the same nest to hatch at different times. The results suggest oviraptors used a hybrid incubation method unlike modern birds.

The surprising cancer link between cats and humans

7:39
Scientists have mapped the genetics of cancer in cats for the first time at scale, uncovering major overlaps with human cancers. Key mutations—like those linked to breast cancer—appear in both species, and some human cancer drugs may also work in cats. Because pets share our environments, these similarities could reveal shared causes of cancer. The research could lead to new treatments that benef…

New drug protects liver after intestinal surgery and boosts nutrient absorption

7:39
A risky but often lifesaving surgery that removes damaged parts of the small intestine can leave patients facing a new threat: serious liver damage with no available treatment. Now, scientists have developed a promising compound that works directly in the gut to shield the liver and improve how the body absorbs nutrients. In mouse studies, the drug boosted weight gain, reduced harmful liver scarr…

You don’t need to lose weight to reverse prediabetes, study finds

7:39
For years, people with prediabetes have been told the same thing: lose weight or risk developing diabetes. But new research flips that idea on its head, showing that blood sugar can return to normal even without shedding pounds. The key isn’t just how much fat you carry—it’s where it’s stored. Harmful fat deep in the abdomen fuels inflammation and disrupts insulin, while fat under the skin can ac…

This simple habit could help seniors live longer and stay independent

7:39
Cycling might be one of the simplest ways for older adults to stay healthier, longer. A 10-year study in Japan found that seniors who rode bicycles had lower risks of needing long-term care and dying—especially those who didn’t drive. Continuing or even starting cycling later in life still delivered noticeable benefits. The results highlight biking as a surprisingly powerful tool for maintaining …

Your daily coffee may be protecting your brain, 43-year study finds

18.března
Your morning coffee or tea could be quietly supporting your brain health. A long-term study found that moderate consumption of caffeinated coffee or tea was linked to an 18% lower risk of dementia and better cognitive performance over time. The benefits appeared strongest at 2–3 cups of coffee or 1–2 cups of tea daily—and even held true for people genetically predisposed to dementia.

These strange pink rocks just revealed a hidden giant beneath Antarctica

18.března
Pink granite boulders sitting mysteriously atop Antarctica’s Hudson Mountains have led scientists to a stunning discovery: a hidden granite mass buried beneath Pine Island Glacier, stretching nearly 100 km wide and 7 km thick. By dating the rocks to the Jurassic period and matching them with gravity signals detected from aircraft, researchers solved a decades-old puzzle about their origin.

These dinosaurs had wings but couldn’t fly

18.března
Some feathered dinosaurs may have briefly taken to the skies—only to give it up later. By studying rare fossils with preserved feathers, researchers uncovered a surprising clue hidden in molting patterns, revealing that Anchiornis likely couldn’t fly at all. Instead of the neat, symmetrical feather replacement seen in flying birds, these dinosaurs showed a messy, irregular molt—something only fli…

AI uses as much energy as Iceland but scientists aren’t worried

18.března
AI’s growing energy use sounds alarming, but its global climate impact may be far smaller than expected. Researchers found that while AI consumes huge amounts of electricity, it barely moves the needle on overall emissions. The real impact is more localized, especially around data centers. Meanwhile, AI could become a powerful tool for building greener technologies.

AI-powered robot learns how to harvest tomatoes more efficiently

18.března
A new tomato-picking robot is learning to think before it acts. Instead of simply identifying ripe fruit, it predicts how easy each tomato will be to harvest and adjusts its approach accordingly. This smarter strategy boosted success rates to 81%, with the robot even switching angles when needed. The breakthrough could pave the way for farms where robots and humans work side by side.
