Social media is awash with videos claiming that taping your mouth closed will improve your sleep – but the evidence doesn't stack up

The JWST has done it again. The powerful space telescope has already revealed the presence of bright galaxies only several hundred million years after the Big Bang. Now, it's sensed light from a galaxy only 280 million years after the Big Bang, the most distant galaxy ever detected.

Should you mow the lawn first or cut the hedge? Mathematics will help you decide what to tackle first, says Peter Rowlett

The premise of Grace Chan’s debut novel – that you can choose to upload yourself to a virtual reality – might sound dated, but this is a stunning big‑picture look at what might lie ahead for us, says Emily H. Wilson

From battling drought to caring for wildlife, shots from the Earth Photo 2025 competition shortlist show how we are coping with a changing world

A huge increase in parking costs in my home of York has provoked outrage. This may sound like a local problem, but reducing car use is an issue for all of us, says Graham Lawton

Feedback is delighted to discover that a team of scientists has tackled the popular school experiment in which children design a device to protect a dropped egg from cracking. But what was the answer?

We have been lucky to dodge nuclear Armageddon so far, but we can't keep trusting to fortune. If we don't want to wipe ourselves out, here's what we need do next, says Mark Lynas

Most parenting manuals end up gathering dust on my bedside table, but Melinda Wenner Moyer's Hello, Cruel World! isn’t one of them

With the US in retreat from climate negotiations, China's Xi Jinping could become the next green global leader

SeaSplat is an image-analysis tool that cuts through the ocean's optical effects to generate images of underwater environments reveal an ocean scene's true colors. Researchers paired the color-correcting tool with a computational model that converts images of a scene into a three-dimensional underwater 'world' that can be explored virtually.

A new camera setup can record three-dimensional movies with a single pixel. Moreover, the technique can obtain images outside the visible spectrum and even through tissues. The development thus opens the door to holographic video microscopy.

A research team has developed the world's first Pixel-Based Local Sound OLED technology. This breakthrough enables each pixel of an OLED display to simultaneously emit different sounds, essentially allowing the display to function as a multichannel speaker array. The team successfully demonstrated the technology on a 13-inch OLED panel, equivalent to those used in laptops and tablets.

By carefully placing nanostructures on a flat surface, researchers have significantly improved the performance of so-called optical metasurfaces in conductive plastics. This is a major step for controllable flat optics, with future applications such as video holograms, invisibility materials, and sensors, as well as in biomedical imaging.

If you've ever sat waiting at the doctor's office to give a blood sample, you might have wished there was a way to find the same information without needles. But for all the medical breakthroughs of the 20th century, the best way to detect molecules has remained through liquids, such as blood. New research, however, could someday put a pause on pinpricks. A group of scientists announced they have created a small, portable device that can collect and detect airborne molecules -- a breakthrough that holds promise for many areas of medicine and public health.
