Jupiter holds secrets at its heart that continue to puzzle scientists. The largest planet in our Solar System has what researchers call a “dilute core” – a central region that doesn’t have sharp boundaries like once expected. Instead of a distinct rocky centre surrounded by layers of gas, Jupiter’s core gradually blends into the hydrogen-rich layers above it, creating a …

Wild rabbits in Colorado have been discovered with concerning horn-like growths protruding from their heads, startling people on social media. Thankfully the condition poses no threat to humans and other animals, with recent sightings also having been reported in Minnesota and Nebraska. The bunnies’ ‘horns’ are a symptom of the Shope papilloma virus, which spreads through the bites of mosquitoes, …

Exercise is a cornerstone of good health and evidence shows it can even help prevent cancers returning following treatment. But new findings are raising an unexpected question: could very high-volume endurance training carry its own risks? At the 2025 American Society of Clinical Oncology meeting, researchers from Inova Schar Cancer Institute reported that a surprising number of dedicated marathon and …

A genetically modified pig lung transplanted into a brain-dead human patient functioned for nine days in a new achievement that reveals both the promise and significant challenges of xenotransplantation. Over the course of the experiment, the patient showed increasing signs of organ rejection before scientists at the First Affiliated Hospital of Guangzhou Medical University in China terminated the experiment, allowing …

Most people know they should drink more water, but our new research reveals an unexpected consequence of falling short: it could be making everyday stress significantly harder to handle. Our study, published in the Journal of Applied Physiology, found that people who drank less than 1.5 litres daily showed dramatically higher levels of cortisol – the body’s primary stress hormone …

Following a comprehensive review of the latest research on hypertension, blood pressure guidelines in the US have been updated to cut risks of heart disease and dementia later in life further than ever.

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth’s history. Our history. Research shows there are little-known chapters in that history, deep within Earth’s past. In fact, Earth’s inner core appears to have another even more inner core within it. “Traditionally we’ve been taught …

Under the cover of darkness, thousands of tiny bumblebee catfish were caught orange finned by police, wriggling their way up a waterfall in Brazil. The boulders of the Aquidauana River waterfall are up to 4 meters high, yet somehow these catfish (Rhyacoglanis paranensis), which are less than 4 centimeters (1.6 inches) long, manage to scale them like mini Olympic rock …

The ways our eyes explore the world change subtly over time, affected by age and illness. A new study now suggests some of those changes could be used to identify problems with memory and cognition. Researchers from Canada and the West Indies built on previous work by searching for variations in eye viewing patterns in people with and without a …

When NASA’s Dawn mission arrived at Ceres in 2015, scientists and the general public got their first detailed look at this strange and beautiful planetoid. As the largest object in the Main Asteroid Belt, accounting for more than 39 percent of its total mass, Ceres is the only object in the belt that has undergone hydrostatic equilibrium (aka. became round …
