July 18, 2026 — A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the ...

July 17, 2026 — A major DNA study has rewritten the koala's evolutionary story, revealing that the species suffered a dramatic population collapse about 100,000 years ago, long before humans arrived in Australia. By calculating the koala's mutation rate for the ...

July 15, 2026 — An unusual leopard gecko that naturally develops aggressive tumors may become an important new model for cancer research. Scientists found its tumors share key genetic changes with human cancers, offering a rare opportunity to study the disease as ...

July 14, 2026 — A deadly fungus has wiped out amphibian populations around the globe, yet some mysteriously recover. Researchers discovered that survivors develop powerful immune defenses while they are still tadpoles, giving them a head start before the fungus can ...

July 14, 2026 — A major review found that people who consumed the most chili peppers had a substantially higher risk of esophageal cancer, though the evidence was less clear for stomach and colorectal cancers. Researchers emphasize that the findings show an ...

July 14, 2026 — The world's longest-running soil warming experiment has revealed an unexpected climate concern. After nearly four decades, researchers found that warming can cause microbes to break down stable soil carbon that scientists once believed was largely ...

July 12, 2026 — Scientists discovered that extreme deep-sea pressure squeezes valuable nutrients out of sinking organic particles, providing an unexpected food source for ocean microbes. The finding could rewrite our understanding of both deep-ocean ecosystems and ...

July 12, 2026 — Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species ...

July 11, 2026 — 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 ...

July 10, 2026 — 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 ...

July 9, 2026 — 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 ...

July 9, 2026 — Oak trees keep absorbing carbon dioxide long after their annual growth has ended, revealing that photosynthesis and wood production are not as closely linked as scientists once believed. The finding could reshape forecasts of how much carbon forests ...
