This adorable sea lion has to eat five to eight percent of its body weight every day to stay healthy and hydrated. Breakthroughs, discoveries, and DIY tips sent six days a week. Over the long and complicated course of evolutionary history, mammals independently turned towards water to make a home multiple times. While many of the warm-blooded animals that abandoned dry land for a watery habitat no longer exist, we still have plenty of stunning examples: Think dolphins, whales, manatees, porpoises. There's even a whole suborder of carnivores called the pinnipeds, which includes seals, sea lions, and walruses who move between land and water.

The visual system of mammals is comprised of parallel, hierarchical specialized pathways. Different pathways are specialized in so far as they use representations that are more suitable for supporting specific downstream behaviours. In particular, the clearest example is the specialization of the ventral (what) and dorsal (where) pathways of the visual cortex. These two pathways support behaviours related to visual recognition and movement, respectively. To-date, deep neural networks have mostly been used as models of the ventral, recognition pathway.

Unlike its land cousin the box turtle, painted turtles do not have a hinged bottom shell that closes when the head is pulled in. Breakthroughs, discoveries, and DIY tips sent every weekday. Winter has officially arrived in the Northern Hemisphere. With today's winter solstice, the days will start to get a little bit longer, but the cold will stick around. We humans typically handle the dipping temperatures by staying inside, sleeping more, and dressing in layers . Here are some unique ways that animals survive winter's deep freeze.

We consider the problem of learning a multi-class classifier from labels as well as simple explanations that we call discriminative features .

The archipelago's total bat tally now stands at 85 different flying mammals. Breakthroughs, discoveries, and DIY tips sent every weekday. A few weeks ago, conservationists announced the milestone discovery of the 1500th known bat species, . October's Bat Appreciation Month celebrations apparently aren't done yet. With only a few days remaining before Halloween, a research team has described another new species residing in the Philippines for the journal .

Environment Animals Wildlife Bats Why do bats spread so many diseases? Survival of the fittest doesn't always mean smartest, fastest, or strongest. Breakthroughs, discoveries, and DIY tips sent every weekday. There are way more bats than you might think. Second only to rodents, bats make up around a fifth of all mammals, with over 1,500 species of winged nightflyers .

In many tasks that require deductive reasoning, such as theorem proving or medical diagnosis, the complexity of proofs can grow without bound via the use of multiple deduction rules and the composition of subproofs.

We present a longitudinal study which evaluates the reasoning capability of frontier Large Language Models over an eighteen month period. We measured the accuracy of three leading models from December 2023, September 2024 and June 2025 on true or false questions from the PrOntoQA dataset and their faithfulness to reasoning strategies provided through in-context learning. The improvement in performance from 2023 to 2024 can be attributed to hidden Chain of Thought prompting. The introduction of thinking models allowed for significant improvement in model performance between 2024 and 2025. We then present a neuro-symbolic architecture which uses LLMs of less than 15 billion parameters to translate the problems into a standardised form. We then parse the standardised forms of the problems into a program to be solved by Z3, an SMT solver, to determine the satisfiability of the query. We report the number of prompt and completion tokens as well as the computational cost in FLOPs for open source models. The neuro-symbolic approach significantly reduces the computational cost while maintaining near perfect performance. The common approximation that the number of inference FLOPs is double the product of the active parameters and total tokens was accurate within 10\% for all experiments.
