Scientists rediscover lost Megalodon fossils—and reveal a 79-foot giant

Several enormous Megalodon vertebrae thought to have been destroyed in 1989 were found sitting unnoticed on a museum shelf. Their analysis strengthens evidence that the giant shark could exceed 24 meters (79 feet) in length and live for nearly a century. Researchers also estimate that its newborns may have measured an astonishing 3.6 meters (12 feet).

Claude Fable 5 AI finds a tiny formula that topples an 87-year-old math conjecture

A mathematician working at Anthropic says he used the AI model Claude Fable 5 to uncover a remarkably simple counterexample to the Jacobian conjecture, a famous problem that has resisted mathematicians for more than a century. The result shows that the conjecture is false in three dimensions and above, although the original two-dimensional version remains unsolved.

This school-bus-sized “terror croc” ate dinosaurs. Now it’s back

A massive crocodilian capable of attacking dinosaurs has been brought back to life as the first scientifically accurate mounted skeleton of Deinosuchus schwimmeri. The 31-foot replica at Georgia’s Tellus Science Museum was built from detailed fossil scans and more than 40 years of research by paleontologist Dr. David Schwimmer, for whom the species was named.

These bizarre new beetles look so stretchy scientists named them Luffy

Scientists have named a newly discovered beetle genus Luffy, inspired by the stretchy hero of the manga and anime One Piece. The insects have unusually long, slender mandibles, antennae, and mouthparts that resemble Luffy’s rubber-like ability to extend his body.

Tiny aerosol particles could supercharge tropical storm clouds

Scientists discovered unusually high water-vapor supersaturation inside deep tropical clouds, creating conditions in which tiny aerosol particles could intensify storm updrafts. The finding suggests earlier studies may have missed the effect because they were looking in the wrong types of clouds.

Daily multivitamin may help older adults stay independent

Taking a daily multivitamin may help older adults preserve the strength and stamina needed for everyday activities. After three years, users reported better functional health than those taking a placebo, although the preliminary findings still require peer review.

Scientists trace the shocking origin of human eyes to an ancient “cyclops”

Researchers say a tiny one-eyed ancestor that lived nearly 600 million years ago may have shaped the evolution of every vertebrate eye, including our own. They also found that its ancient median eye lives on today as the pineal gland, which helps synchronize our sleep with daylight.

A healthier global diet could cut farm emissions by 85%

A global shift toward healthier diets could sharply reduce livestock farming, free up agricultural land, and cut emissions from land-use change by 85% by 2050. At the same time, fruit, vegetable, nut, and legume production could soar, creating a sweeping transformation of what the world grows and eats.

New programmable photonic chip can control how fast light moves

Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could provide the delays, synchronization, and buffering functions needed to make light-based computing more practical. A single chip could eventually perform several tasks that currently require separate devices, potentially reducing energy use, cost, and complexity in AI servers and data centers.

Coffee may protect your heart but energy drinks could harm it

For most adults, a daily caffeine habit may be safer for the heart than many people assume. A new American Heart Association review found that up to 400 milligrams of caffeine a day, roughly three to five cups of regular black coffee, is generally safe and may even be linked to lower risks of heart disease, stroke, heart failure, and Type 2 diabetes. But the source matters: highly concentrated energy drinks and shots can sharply raise blood pressure and trigger irregular heart rhythms.

Scientists just discovered a lost branch of Australia’s marsupials

Fossils from Queensland suggest a newly recognized marsupial order may have survived in Australia for around 35 million years, rewriting part of the story of how the continent's unique mammals evolved. The discovery challenges the idea that Australia's marsupials all came from a single straightforward ancestral lineage.

Scientists identify the rare meteorite that killed the dinosaurs 66 million years ago

The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have delivered the deadliest blow.

Common antidepressant may ease long COVID’s crushing fatigue

A low-cost antidepressant may offer new hope for people struggling with long COVID fatigue. In a randomized clinical trial involving 399 adults, fluvoxamine significantly reduced fatigue and improved quality of life compared with a placebo, making it one of the first medications to show meaningful benefits for this disabling condition.

New Alzheimer's drug repairs DNA damage and reduces brain inflammation

A drug originally developed for spinal cord injury may offer a fresh approach to treating Alzheimer’s disease. In mouse studies, KCL-286 repaired dangerous DNA damage, reduced inflammation, and targeted multiple disease-related pathways instead of focusing on just amyloid or tau. Since it has already cleared an initial human safety trial, researchers believe it could move more quickly into Alzheimer’s clinical testing.

NASA's James Webb Space Telescope reveals a strange atmosphere on a hellish lava planet

NASA's James Webb Space Telescope has revealed new details about the blistering lava planet 55 Cancri e, where temperatures are high enough to melt rock. The data indicate the planet likely has a hydrogen-rich atmosphere shaped by gases escaping from its molten interior, with signs that volcanic outgassing may even create temporary clouds.

Why have humans collected crystals for 780,000 years? Chimpanzees may hold the answer

Chimpanzees showed a remarkable attraction to crystals, choosing them over ordinary stones and studying them with intense curiosity. The results suggest that the same unusual features may have fascinated early humans long before crystals had any practical use.

New dark matter theory could solve multiple cosmic mysteries at once

Dark matter may be far more complicated than scientists once believed. A new study suggests it could consist of at least two different kinds of particles that slowly separate over time, with heavier particles sinking toward the centers of galaxies and lighter ones drifting outward. This simple idea could explain several puzzling cosmic observations that have frustrated astronomers for years, from unusually diffuse dwarf galaxies to surprisingly dense dark matter clumps that bend light through gravitational lensing.

Future moon landings could wipe out clues to how life began on Earth

A new study suggests spacecraft exhaust could quickly contaminate the moon's most scientifically valuable regions, potentially masking ancient clues about how life began on Earth. Researchers say future lunar missions should consider new ways to reduce and monitor this pollution before it becomes widespread.

Common blood pressure drug could make cancer therapy far more powerful

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.

Scientists just debunked a dangerous baby rattlesnake myth

A new study debunks the long-standing claim that baby rattlesnakes are more dangerous than adults. Researchers found that young rattlesnakes can control their venom just like adults, while adult snakes usually inject much more venom and cause more serious bites. The team also uncovered how the myth spread through decades of inaccurate news reports and misleading quotes from trusted sources.
