Cannabis use may quadruple diabetes risk

A massive study of over 4 million adults has revealed that cannabis use may nearly quadruple the risk of developing diabetes. Despite some earlier suggestions that cannabis might have metabolic benefits, this large analysis found significantly higher diabetes rates among users, even after adjusting for other health factors.

Surprising giant DNA discovery may be linked to gum disease and cancer

Scientists in Tokyo have uncovered “Inocles,” massive strands of extrachromosomal DNA hidden inside bacteria in human mouths. These giants, overlooked by traditional sequencing, could explain how oral microbes adapt, survive, and impact health. Found in nearly three-quarters of people, Inocles carry genes for stress resistance and may even hint at links to diseases like cancer, opening a whole new frontier in microbiome research.

These dinosaur eggs survived 85 million years. What they reveal is wild

Dating dinosaur eggs has always been tricky because traditional methods rely on surrounding rocks or minerals that may have shifted over time. Now, for the first time, scientists have directly dated dinosaur eggs by firing lasers at tiny eggshell fragments. The technique revealed that fossils in central China are about 85 million years old, placing them in the late Cretaceous period. This breakthrough not only sharpens our timeline of dinosaur history but also offers fresh clues about ancient populations and the climate they lived in.

Life on Mars? NASA discovers potential biosignatures in Martian mudstones

NASA’s Perseverance rover has discovered mudstones in Mars’ Jezero Crater that contain organic carbon and unusual textures hinting at possible biosignatures. These findings suggest that ancient Martian environments may have supported chemical processes similar to those on Earth, where microbial life thrives. While the team stresses they have not discovered evidence of life, the rocks show chemical reactions and mineral formations that could point to biological activity.

The ocean’s most abundant microbe is near its breaking point

Tiny ocean microbes called Prochlorococcus, once thought to be climate survivors, may struggle as seas warm. These cyanobacteria drive 5% of Earth’s photosynthesis and underpin much of the marine food web. A decade of research shows they thrive only within a narrow temperature range, and warming oceans could slash their populations by up to 50% in tropical waters.

Antarctica’s frozen heart is warming fast, and models missed it

New research has revealed that East Antarctica’s vast and icy interior is heating up faster than its coasts, fueled by warm air carried from the Southern Indian Ocean. Using 30 years of weather station data, scientists uncovered a hidden climate driver that current models fail to capture, suggesting the world’s largest ice reservoir may be more vulnerable than previously thought.

Seven blood molecules that could explain why you’re always sleepy

Scientists discovered seven molecules in the blood linked to excessive daytime sleepiness, a condition that affects one in three Americans and raises the risk of heart disease, obesity, and diabetes. The study highlights the role of both diet and hormones, finding that omega-3 and omega-6 fatty acids may protect against drowsiness, while compounds like tyramine may worsen it.

Scientists just made the first time crystal you can see

Physicists at the University of Colorado Boulder have created the first time crystal that humans can actually see, using liquid crystals that swirl into never-ending patterns when illuminated by light. This breakthrough builds on Nobel laureate Frank Wilczek’s 2012 theory of time crystals—structures that move forever in repeating cycles, like a perpetual motion machine or looping GIF. Under the microscope, these crystals form colorful, striped patterns that dance endlessly, opening possibilities for everything from anti-counterfeiting features in money to futuristic methods of storing digital information.

Scientists just cracked a 60-million-year-old volcanic mystery

Cambridge scientists discovered that thin, weak zones in Earth’s plates helped spread Iceland’s mantle plume across the North Atlantic, explaining why volcanic activity once spanned thousands of kilometers. These ancient scars not only shaped the landscape but still influence earthquakes and could point to untapped geothermal energy.

Scientists just made CRISPR three times more effective

Northwestern scientists have developed a new nanostructure that supercharges CRISPR’s ability to safely and efficiently enter cells, potentially unlocking its full power to treat genetic diseases. By wrapping CRISPR’s tools in spherical DNA-coated nanoparticles, researchers tripled gene-editing success rates, improved precision, and dramatically reduced toxicity compared to current methods.
