Climate Change: A Fleet Of Saildrones Patrol Oceans

A fleet of unmanned surface vehicles equipped with AI and a suite of scientific sensors are currently mapping the ocean floor, counting fish populations and monitoring ocean and weather conditions all over the planet in the fight against climate change. CNET’s Stephen Beacham spoke with Saildrone Inc. Vice President of Ocean Mapping Brian Connon to learn more about Saildrone’s mission.

Book Reviews: ‘The Self-Assembling Brain’ – The Future Benefits For AI

As Peter Robin Hiesinger argues, “the information problem” underlies both fields, motivating the questions driving forward the frontiers of research. How does genetic information unfold during the years-long process of human brain development―and is there a quicker path to creating human-level artificial intelligence? Is the biological brain just messy hardware, which scientists can improve upon by running learning algorithms on computers? Can AI bypass the evolutionary programming of “grown” networks? Through a series of fictional discussions between researchers across disciplines, complemented by in-depth seminars, Hiesinger explores these tightly linked questions, highlighting the challenges facing scientists, their different disciplinary perspectives and approaches, as well as the common ground shared by those interested in the development of biological brains and AI systems. In the end, Hiesinger contends that the information content of biological and artificial neural networks must unfold in an algorithmic process requiring time and energy. There is no genome and no blueprint that depicts the final product. The self-assembling brain knows no shortcuts.

Science Podcast: Snow-Covered ‘Zombie Fires’, Flashy Plant Research

Smouldering fires lay dormant before bursting back into flame in spring.

In this episode:



00:56 The mysterious overwintering forest fires

Researchers have shown that fires can smoulder under snow in frozen northern forests before flaring up the following spring. Understanding how these so-called ‘zombie’ fires start and spread is vital in the fight against climate change.

Science: Miocene Apes And Human Evolution (Video)

More than ten million years ago, the world was brimming with a wide variety of apes. Scientists studying the ones that are still alive today can learn a lot about human evolution—but they miss out on many clues that can only be found from the apes that went extinct. Watch to learn how fossil apes have strengthened ideas about how humans evolved, and what steps we can take to learn even more about our ancient ancestors. Read the review: https://scim.ag/3hw5PVx

11:35 A metal-free rechargeable battery

Lithium-ion batteries have revolutionised portable electronics, but there are significant issues surrounding their recyclability and the mining of the metals within them. To address these problems, a team of researchers have developed a metal-free rechargeable battery that breaks down to its component parts on demand.
