Step 1: Insert bacteria ("Wolbachia") into mosquitoes.

Step 2: Release mosquitoes.

Step 3: Watch Dengue rates plummet.

Phenomenal results from Singapore.

Does AI already have human-level intelligence? The evidence is clear The vision of human-level machine intelligence laid out by Alan Turing in the 1950s is now a reality. Eyes unclouded by dread or hype will help us to prepare for what comes next.

Goddness, there's lots to say about this. Good to see the case pro laid out in detail. I wonder if Nature will be publishing the counter-argument too?

🔬 London 2026 🇬🇧 Complexity72h is open for applications!

Young researchers in #ComplexSystems, come to London, June 22–26, 2026 @nunetsi.bsky.social

What is Complexity72h? Participants form teams and work 72 hours on original research projects, guided by expert tutors.



More details below:

Globally, seasonal influenza kills an average of 700,000 people each year from respiratory disease or cardiovascular disease.

During large flu pandemics, when influenza strains evolved substantially, the death toll was even higher.

Neat work, showing that the entire evolution of a variant of concern can happen in one persistently infected individual over about a year.

Antibodies elicited by the 2025-2026 influenza vaccine in humans A new H3N2 variant (named subclade K) possesses several key hemagglutinin substitutions and is circulating widely during the 2025-2026 influenza season. In this report, we completed experiments to det...

We find that subclade K viruses are antigenically advanced; however, this year's flu vaccine surprisingly elicited antibodies in many individuals that efficiently recognized these viruses. The implications are clear: go get this year’s vaccine if you haven’t already!

Discovering the laws behind complex networked systems - Nature Computational Science A recent study shows that neural symbolic regression offers a route to automated discovery of governing equations for network dynamics across high-dimensional complex systems.

In a brief 𝘕𝘢𝘵𝘶𝘳𝘦 𝘊𝘰𝘮𝘱𝘶𝘵𝘢𝘵𝘪𝘰𝘯𝘢𝘭 𝘚𝘤𝘪𝘦𝘯𝘤𝘦 piece, E. Valdano and I discuss recent progress in automated scientific discovery of governing laws for complex networked systems, where neural symbolic regression can extract interpretable laws from high-dimensional dynamics.
