Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes. The highest intake was linked to cognitive aging roughly 1.6 years faster than the lowest intake. Researchers stressed that more studies are needed before concluding that sweeteners are the cause.

Researchers found that the common blood pressure drug telmisartan can significantly improve the performance of the cancer drug olaparib, potentially expanding its benefits beyond patients with BRCA-related tumors. The combination is already being tested in human clinical trials after showing strong immune-boosting and anticancer effects in preclinical studies. Read more ›

Two striking Asian praying mantis species that have rapidly spread across Europe have now been officially classified as invasive, raising new concerns about their impact on native wildlife. Boosted by climate change and urban environments, these fast-breeding predators are expanding northward, where they prey on native insects, pollinators, and even small vertebrates while also reducing native mantis populations through deadly mating interactions.

Researchers discovered that electricity can dramatically reshape how heat flows through certain ceramic materials, increasing heat conduction by almost threefold in a preferred direction. The unexpected result could lead to much more efficient cooling technologies and energy-saving devices. Read more ›

Researchers have achieved a major milestone by creating a long-sought two-dimensional quantum material and confirming its unusual conducting edge states. The ability to control these states through strain could make the material a promising platform for future room-temperature quantum electronics. Read more ›

Many of the body's biggest flaws are the result of evolution building on old designs instead of starting over. Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that worked well enough for survival but still leave us prone to pain, injury, and disease. Structures like the appendix and ear muscles also remain because they were never harmful enough for evolution to eliminate. Together, these features tell... Read more ›

Scientists have discovered a previously unknown fossil goose that challenges a decades-old theory about the evolution of New Zealand's birds. The find suggests the country's giant flightless geese evolved from much more recent arrivals, revealing a far more dynamic evolutionary history than once believed. Read more ›

A detailed independent study found that SpaceX's Starship is every bit as revolutionary as expected, while revealing both its impressive capabilities and its biggest remaining hurdles. It also introduces an ambitious European rocket concept that could offer a very different route to affordable super heavy launches. Read more ›

A new study found that dietary fiber can determine whether beneficial intestinal worms help reduce inflammation or become essentially inactive. With plenty of fiber, the worms remained healthy and supported an anti-inflammatory response, while a low-fiber diet pushed them into a hibernation-like state that eliminated those benefits. Researchers also found that fiber-rich diets promoted healthier gut bacteria, whereas Western-style diets reduced microbial diversity and encouraged less desirable microbes. Read more ›

A newly discovered underwater volcanic eruption north of Papua New Guinea is unfolding in one of the world's most poorly mapped ocean basins. Satellites have spotted steam plumes, ash, thermal hotspots, and huge floating pumice rafts, suggesting magma is rising surprisingly close to the surface. Scientists are now watching closely to see if the eruption creates a new island, offering a rare opportunity to observe the birth of new land... Read more ›

Heavy marijuana smoking may raise the risk of lung cancer and several head and neck cancers, according to growing research, but many important questions remain unanswered. Scientists are still trying to determine how much marijuana use is enough to significantly increase cancer risk. Edibles have not been linked to lung cancer so far, while the long-term effects of vaping marijuana and secondhand marijuana smoke are still being investigated. Read more ›

Researchers solved the mystery of how soft lithium dendrites crack the hard ceramic inside solid-state batteries, triggering short circuits. The breakthrough could help engineers build safer, longer-lasting batteries for smartphones, electric vehicles, and other electronics. Read more ›

A next-generation pesticide designed to kill crop pests may also be interfering with the reproductive health of bumblebees. Researchers discovered that low-dose exposure to sulfoxaflor changed gene activity, especially in tissues involved in reproduction, raising concerns about long-term impacts on bee populations. Because pollinators are essential for about one-third of the world's food production, finding ways to protect them while controlling pests has become increasingly important. Read more ›

Mount Etna has long puzzled geologists because it doesn't fit any of the three classic ways volcanoes are thought to form. A new study suggests it may instead be fueled by ancient pockets of magma that are pushed upward through cracks created by shifting tectonic plates. If confirmed, Etna could belong to a rare fourth category of volcano, revealing that much larger volcanoes can form through processes previously associated only... Read more ›

Scientists have identified new clues that could help astronomers spot one of the most famous hypothetical alien megastructures: a Dyson sphere. The study finds that red dwarfs and white dwarfs are the most promising stars to examine, since advanced civilizations could potentially build energy-harvesting swarms around them more easily. These objects would stand out by glowing in infrared light instead of visible light, lacking the dusty signatures of ordinary stars,... Read more ›

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. Read more ›

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. Read more ›

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. Read more ›
