New analysis of bone growth rings shows the'tyrant lizard king' grew very slowly. Breakthroughs, discoveries, and DIY tips sent six days a week. Based on the annual growth rings (like those on trees) within fossilized leg bones, scientists estimate that usually reach adulthood at around 25 years old. However, new research argues that their growth phase lasted significantly longer. They may have become fully grown--approximately eight tons--after 40 years.

A study by three US researchers revealed that T. rex didn't reach their full adult size until around age 40, maturing gradually and steadily over decades rather than stopping abruptly earlier in life . This means the oldest T. rex likely lived well beyond their 40s, enjoying a prolonged'adolescence' where they kept getting bigger and stronger into middle age.

Environment Animals Wildlife A professor kept a pet worm for 20 years. It just set a record. Baseodiscus the Eldest lives a chill life in Virginia. Breakthroughs, discoveries, and DIY tips sent every weekday. Jonathan Allen, a biology professor at The College of William & Mary in Virginia, has a very strange pet: a very long ribbon worm () named Baseodiscus the Eldest, or just B for short.

Scientists at EPFL, the Royal Netherlands Institute for Sea Research and Wageningen University & Research have developed a new deep-learning model for counting the number of seals in aerial photos that is considerably faster than doing it by hand. With this new method, valuable time and resources could be saved which can be used to further study and protect endangered species. Ecologists have been monitoring seal populations for decades, building up vast libraries of aerial photos in the process. Counting the number of seals in these photos require hours of meticulous work to manually identify the animals in each image. A cross-disciplinary team of researchers including Jeroen Hoekendijk, a PhD student at Wageningen University & Research (WUR) and employed by the Royal Netherlands Institute for Sea Research (NIOZ), and Devis Tuia, an associate professor and head of the Environmental Computational Science and Earth Observation Laboratory at EPFL Valais, have come up with a more efficient approach to count objects in ecological surveys.

The way seals appear in aerial photos can vary significantly from one batch to the next, depending on the altitude and angle at which the photo was taken. The research team therefore evaluated robustness to such variation. In addition, to demonstrate the potential of their deep-learning model, the scientists tested their approach on a fundamentally different dataset, of a much smaller scale: images of microscopic growth rings in fishbones called otoliths. These otoliths, or hearing stones, are hard, calcium carbonate structures located directly behind a fish's brain. The scientists trained their model to count the daily growth rings visible in the images, which are used to estimate the age of the fish.
