The obesity rate has more than doubled in the last 30 years, affecting more than one billion people worldwide. This prevalent condition is also linked to other metabolic disorders, including type 2 diabetes, cardiovascular diseases, chronic kidney disease, and cancers. Current treatment options include lifestyle interventions, bariatric surgery, and GLP-1 drugs like Ozempic or Wegovy,…
Astronomers have discovered potentially the most massive black hole ever detected. The cosmic behemoth is close to the theoretical upper limit of what is possible in the universe and is 10,000 times heavier than the black hole at the center of our own Milky Way galaxy. It exists in one of the most massive galaxies…
It sounds like science fiction: a spacecraft, no heavier than a paperclip, propelled by a laser beam and hurtling through space at the speed of light toward a black hole, on a mission to probe the very fabric of space and time and test the laws of physics. But to astrophysicist and black hole expert…
Watch: Large fireball seen shooting across sky over Southeastern US A meteorite that crashed into a home in the US is older than planet Earth, scientists have said. The object flew through the skies in broad daylight before exploding across the state of Georgia on 26 June, Nasa confirmed. Researchers at the University of Georgia…
Artistic concept of what the gas giant orbiting Alpha Centauri A could look like ESA/Webb Copyright: NASA, ESA, CSA, STScI, R. Hurt (Caltech/IPAC) A giant planet the size of Saturn orbiting a sun-like star has potentially been identified in our nearest neighbouring stellar system, Alpha Centauri. At just four light years from Earth, Alpha Centauri…

Cage fungus Alison Pouliot “I’ve been hanging around fungi for more than 30 years now, working more at the scientific end. But this time I wanted to really explore the aesthetics of fungi,” says photographer, writer and ecologist Alison Pouliot. “Many of them are aesthetically beautiful. But they are also bizarre, unusual and crazy. I…
Honeybees routinely battle infectious fungi, bacteria, mites and viruses Anthony Brown/Alamy Two seemingly innocuous viral infections in adult honeybees may be secretly insidious, meddling with the insects’ airborne athletics. One virus makes them fly faster, while the other pumps the brakes. Honeybees routinely battle infectious fungi, bacteria, mites and viruses – some of which can…
A Hubble Space Telescope image of the interstellar comet 3I/ATLAS. Background stars appear as streaks because the telescope was tracking the comet NASA, ESA, David Jewitt (UCLA)/Joseph DePasquale (STScI) Telescopes trained on the interstellar comet 3I/ATLAS have revealed that it looks much like comets found in the outer reaches of our own solar system. However,…
Researchers show astrocytes can be tuned to reverse some obesity-driven brain and metabolic changes, revealing untapped therapeutic potential. Credit: Shutterstock Fatty diets and obesity affect the structure and function of astrocytes1, the star-shaped brain cells located in the striatum, a brain region involved in the perception of pleasure generated by food consumption. What is even…
