Jurassic Tadpole Fossil Unearthed in Argentina Sets New Record

A 160-million-year-old tadpole fossil, discovered in Argentina, has set a new record as the oldest known tadpole, belonging to the ancient frog species Notobatrachus degiustoi. This find pushes the evidence of tadpole metamorphosis back by 15 million years and provides insights into the early evolution of the anuran life cycle. The fossil's preservation reveals key features of modern tadpoles, such as the filter-feeding system, indicating that tadpole gigantism existed among stem-anurans. The research, led by Mariana Chuliver, was published in Nature.

Opal's Tadpole: The Ultimate High-End Webcam for Laptops

Opal has launched its second camera, the Tadpole, a tiny webcam designed specifically to be clipped to laptops. Weighing about as much as an AA battery, the Tadpole is small, compatible with Windows devices, and easy to use. It features a 48-megapixel Sony IMX582 sensor, an f/1.8 lens, and the ability to capture video up to 4K, providing a significant improvement over built-in laptop webcams. The Tadpole also includes a built-in mic called the "VisiMic," although its noise cancellation capabilities are not noticeably better than other systems. Overall, the Tadpole offers a hassle-free experience and is aimed at frequent travelers who want to upgrade their video meetings on the go.
