Surprise! Stinkbugs have a symbiotic organ
It’s not unusual for insects to have ears on their legs, but when researchers took a closer look at what was thought to be an eardrumlike structure on female Japanese dinidorid stinkbugs (Megymenum gracilicorne), they got a surprise: a previously unknown type of symbiotic organ. Inside, the stinkbugs nourish symbiotic fungi, which they carefully rub over their freshly laid eggs. The fungi grow over the clutch like a blanket, shielding the eggs against the advances of wasps (Trissolcus brevinotaulus) looking to lay their own offspring inside.

These papers exist, but the authors don’t
In 2015 and 2016, mathematician Beatriz Ychussie published four papers and reviewed multiple manuscripts for reputable journals — an impressive performance for someone who doesn’t exist. Ychussie was fabricated by a paper mill — a company that sells fake research papers — and is just one of dozens of examples of mills duping publishers with fake academics. To combat this fraud, publishers are debating more stringent measures to confirm the identity of authors and reviewers. But some of these checks risk excluding scholars who aren’t based at well-known institutions and those in low- and middle-income countries, say experts.
The future of animal-testing alternatives
NAMs — short for ‘novel alternative methods’ or ‘new approach methodologies’ — are biomedical research techniques that don’t involve the use of animals.
• One group of researchers argue that NAMs are the future. They urge journals, regulators and funders to adjust their priorities to ensure that the use of novel alternatives to animal testing are applauded, not penalized.
• But simply ending animal testing isn’t the answer, argues biomedical researcher Kent Lloyd. The polarized debate over NAMs risks distracting scientists from a dispassionate assessment of the best model for the job, he says.

A lesson for PhD supervisors
Supportive supervision leads to happier PhD students, reveals Nature’s 2025 global survey of more than 3,700 doctoral students. “Group leaders might feel that modern academic life leaves little space for long conversations. But even short, regular check-ins can make a difference,” suggests a Nature editorial. “Time spent with the next generation of scientists is an investment.”

A rewilding project in the United Kingdom has been captured on canvas to give an artistic perspective on biodiversity and climate change solutions. Thirty artists took part in a year-long project to observe land that had been ploughed up for crops during the World War II ‘Dig for Victory’ campaign. The Society of Wildlife Artists Massingham Heath Project show ends on Saturday in London and continues online. (Eastern Daily Press | 4 min read) (Massingham Heath field margin by Brin Edwards)
