Dense breast tissue can make tumours hard to spot on mammogram scans, but adding another step to this screening programme could help identify such cases
A multi-sensor detection of an intense gamma-ray flash, which occurs when two lightning leaders collided, has been observed. Observations across a wide radiation spectrum enabled precise measurement of the electric current produced during this extreme event, and demonstrated that the gamma-ray flash preceded the collision of the lightning leaders between the thundercloud and the ground.

A serendipitous observation has led to a surprising discovery: a new class of nanostructured materials that can pull water from the air, collect it in pores and release it onto surfaces without the need for any external energy. The research describes a material that could open the door to new ways to collect water from the air in arid regions and devices that cool electronics or buildings using the power of evaporation.
An artificial intelligence technique for detecting DNA fragments shed by tumors and circulating in a patient's blood could help clinicians more quickly identify and determine if pancreatic cancer therapies are working.
In 2022 a team discovered that high levels of OH radicals can be generated indoors, simply due to the presence of people and ozone. This means: People generate their own oxidation field and change the indoor air chemistry around them within their own personal space. Now, in a follow-up study again in cooperation with an international research team, they found that commonly applied personal care products substantially suppress a human's production of OH radicals. These findings have implications for the indoor chemistry, the air quality of occupied spaces, and human health, since many of the chemicals in our immediate vicinity are transformed by this field.
Researchers have discovered a new class of materials -- called intercrystals -- with unique electronic properties that could power future technologies. Intercrystals exhibit newly discovered forms of electronic properties that could pave the way for advancements in more efficient electronic components, quantum computing and environmentally friendly materials, the scientists said.

Some 13,000 years ago, the Sun emitted a huge belch of radiation that bombarded Earth and left its imprint in ancient tree rings. That solar storm was the most powerful one ever recorded. The next strongest was the 1839 Carrington Event. It was spurred by a huge solar flare that triggered a powerful geomagnetic storm at Earth. The resulting "space weather" disrupted telegraph communications around the world. Today, as we move through this year's "solar maximum", a period of solar activity that occurs every 11 years, scientists want to prepare governments for the effects of severe solar storms.
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.
