A nearly 50-year-old mystery involving disappearing frogs in Brazil may finally be solved, with scientists uncovering evidence that a deadly fungus swept through the region and devastated vulnerable species. Remarkably, many frog populations have since rebounded, suggesting they developed greater tolerance to the disease that once threatened their survival.
Scientists have uncovered an unexpected connection between inflammation during pregnancy, placental damage, and autism-like traits in male mice, while females appeared naturally protected. The discovery could help explain why autism is diagnosed more frequently in boys and reveal new opportunities for early intervention.
Astronomers using the James Webb Space Telescope (JWST) have confirmed a massive, dust-rich galaxy called Leviathan in the early universe. Seen when the universe was roughly 1.5 billion years old, the galaxy has its stars spread out rather than in a concentrated fashion. A paper, describing its strange stellar distribution, was posted to the arXiv preprint server on Oct. 19.
Eating an avocado and a cup of mango every day may provide surprising benefits for heart health, according to a new study involving adults with prediabetes. After just eight weeks, participants experienced significant improvements in blood vessel function and diastolic blood pressure, particularly among men. These benefits occurred without weight gain or changes in calorie intake, suggesting that the nutrient-rich combination could support cardiovascular health through a simple dietary adjustment.
A massive new study reveals that intelligence plays a surprisingly limited role in children's reading success, while visual processing showed no meaningful connection at all. Instead, the strongest predictors are sound recognition, vocabulary, and background knowledge, offering new clues about how to help struggling readers.
The second Trump administration has dismantled, disrupted or weakened many of the country’s scientific bodies
A start-up valued at more than $1 billion wants to fly cargo planes with no one in the cockpit. First it needs to prove to regulators that they’re safe without a human aboard
Dogs are constantly passing gas. So why don’t cats seem to?
Scientists have discovered all five essential nucleobases used in DNA and RNA in pristine samples from asteroid Ryugu, revealing that key ingredients for life existed in space billions of years ago. The remarkable finding adds to growing evidence from other asteroids and meteorites that these molecules were widespread throughout the early Solar System.
Europe’s Hera spacecraft has captured its first clear view of two asteroids involved in NASA’s historic 2022 experiment to redirect a potentially dangerous space rock. Now approaching the pair, Hera will investigate the mysterious aftermath of the collision and uncover why the asteroid shifted far more than scientists predicted.
NASA’s Voyager 1 is approaching an extraordinary milestone nearly 50 years after its launch, even as engineers battle dwindling power and mysterious technical problems. A clever energy-saving maneuver has extended the spacecraft’s scientific mission, while an unexplained 48-hour communications blackout recently gave NASA a scare. On November 18, Voyager 1 will reach a distance of one light-day from Earth, making even the simplest round-trip communication take 48 hours.
Scientists have discovered that a drug originally developed for spinal cord injuries can tackle several key features of Alzheimer’s disease, including DNA damage and inflammation. Already tested for initial safety in humans, the experimental treatment could offer a faster path toward therapies that target the disease at its roots.
The demand for donkey hides has grown exponentially over the past 15 years, driven mainly by demand from China. Lauren Johnston is a specialist on China trade with Africa. She has spent several years looking into the donkey trade, and has just published a book, "China, Africa and the Market for Donkeys." She answers questions about what she found.
In the 2025 federal election, Canadians voted at the highest rate since 1993. Explanations for high or low turnout usually focus on the national election campaign, including how close the race was and what seemed to be at stake.
Simon Fraser University researchers are zeroing in on how global forestation efforts impact our climate system beyond CO₂ removal in a new study.
Scientists at CERN's Large Hadron Collider have uncovered compelling new evidence that even relatively small atomic collisions can recreate the extraordinary state of matter that filled the universe moments after the Big Bang. Known as quark-gluon plasma, this exotic substance forms at temperatures more than 100,000 times hotter than the center of the Sun, causing ordinary particles to break apart into their fundamental building blocks.
The dwarf planet Ceres is arguably one of the most overlooked and underappreciated planetary objects in the solar system. This could be because while Ceres has the same dwarf planet designation as Pluto, Ceres is largely considered an "asteroid" since it resides in the main asteroid belt. However, along with being the largest object in the main asteroid belt, Ceres accounts for between 25% and 30% of the belt's total mass.
A new study finds that tropical areas often thought to be safe from the effects of climate change are actually experiencing significant changes in rainfall and extreme temperature events. The paper, "Shifting climate in Caribbean tropical forests: Long-term trends at La Selva (Costa Rica) and El Verde (Puerto Rico)," is published in PLOS Climate.
A new historical analysis challenges the received wisdom as to why Chinese characters developed their distinctive square shapes. The work, published in the International Journal of Arts and Technology, argues that their shape resulted from interacting linguistic, technological and cultural factors rather than a single cause.
Scientists have discovered a possible loophole in the laws that normally prevent black holes from splitting apart, suggesting that extremely fast-spinning black holes might divide into two. The surprising finding raises the possibility of an entirely new black hole phenomenon that future telescopes could potentially detect.
