Researchers report that reef-dwelling hogfish have light-sensitive cells embedded in their skin, allowing the animals to sense brightness and adjust their colour without relying solely on eyes. The study, published in Nature, shows this skin-based photoreception can continue to influence colour change even after death. Hogfish live in Atlantic reefs and can shift hues in milliseconds. Those rapid changes aid camouflage, social signalling and may help with temperature regulation and attracting mates.

Researchers led by Itzhak Khait at Tel Aviv University have found that some plants produce audible, high-frequency sounds when they are stressed or damaged. The team tested tomato and tobacco plants and recorded ultrasonic clicks that arise during drought stress or after cutting. Sensitive microphones and acoustic analysis allowed detection of these sounds from as far as five meters, suggesting plants may broadcast information about their physical condition.

Scientists presented results from the OPERA study showing artificial intelligence can analyze heart ultrasound scans in about one minute, compared with roughly 30 minutes for trained human experts. The project, led by the University of Glasgow in partnership with AstraZeneca and NHS trusts including Greater Glasgow & Clyde and the Golden Jubilee, demonstrated the AI’s ability to interpret echocardiograms quickly and consistently during a presentation at the European Society of Cardiology conference in Amsterdam.

Comedy writers and performers say telling a good joke is harder than it looks: timing and delivery can make or break a punchline. Jokes work by surprising the listener with an unexpected twist, clever wordplay, or absurd imagery that creates a vivid mental picture. Short, sharp jokes often land best because they set up an idea quickly and then flip it — for example, an Edinburgh Fringe-winning pun: "I started dating a zookeeper, but it turned out he was a cheetah."
