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 and conservationists are debating de-extinction, the idea of bringing extinct species back using modern genetic tools. Advances such as PCR, genome sequencing and gene editing have made it technically plausible to reconstruct genomes from preserved DNA. Companies like Colossal Biosciences aim to use these methods to create proxy woolly mammoths by editing Asiatic elephant DNA. Proponents argue such projects could help restore lost ecological functions and biodiversity.

Scientists and doctors point out that many health problems run in families, and the diseases now affecting older baby boomers can offer a warning about what people might face later in life. Advances in DNA sequencing make it possible to find gene variants that raise the chances of heart disease, diabetes and some cancers. Identifying those risks early gives doctors and patients options for monitoring, preventive treatment and tailored medical care.

Spain's annual Tomatina festival draws thousands each year to the town of Buñol, where participants playfully pelt one another with overripe tomatoes. This year about 15,000 people, many tourists, threw roughly 120 tonnes of fruit, turning streets and buildings into red pulp. The event lasts about an hour, and people commonly wear goggles and old clothes; there is a small participation fee of about €12 to help manage the crowd.
