Why it's high time we stopped anthropomorphising ants We have long drawn parallels between ants and humans. Now we are comparing the insects to computers. Pollution is making many cities unlivable for their human inhabitants, but it is also tearing ant families and communities apart. Ants recognise each other by sniffing a thin layer of hydrocarbons on the outside of their exoskeletons; each colony has a specific "smell". But a new study reveals that ozone emissions can change the structure of these hydrocarbons.

Hannah Fry: 'AI can do some superhuman things - but so can forklifts' Mathematician Hannah Fry travels to the front lines of AI in her new BBC documentary AI Confidential with Hannah Fry. The chances are that you think about artificial intelligence far more today than you did five years ago. Since ChatGPT was launched in November 2022, we have become accustomed to interacting with AIs in most spheres of life, from chatbots and smart home tech to banking and healthcare. But such rapid change brings unexpected problems - as mathematician and broadcaster Hannah Fry shows in AI Confidential With Hannah Fry, a new three-part BBC documentary in which she talks to people whose lives have been transformed by the technology. She spoke to New Scientist about how we should view AI, its role in modern mathematics - and why it will upend the global economy.

Chile's Torres Del Paine is famous for its stunning landscapes, but it's also home to a fierce predator: the puma. These majestic creatures feed primarily on guanacos, although the hunting success rate is not very high, especially for female pumas. The photographer followed this female and her two cubs for several days, before witnessing her hunting. Breakthroughs, discoveries, and DIY tips sent six days a week. In Chile's famous Torres Del Paine National Park, a mother puma with her two cubs in tow attacks a guanaco.

The ability of a brain or a neural network to efficiently learn depends crucially on both the task structure and the learning rule.

Training a policy in a source domain for deployment in the target domain under a dynamics shift can be challenging, often resulting in performance degradation.
