Bird flu could become the next human pandemic – and politicians aren't paying attention | Devi Sridhar
We have the tools to prepare, but post-Covid fatigue and a lack of political will mean they aren’t being used
Last month a pet dog in Canada died of H5N1, also known as bird flu, after eating a wild goose. Worryingly this follows a pattern, with an increasing number of bird flu cases appearing in mammals who come into contact with an infected bird, dead or alive.
When you see a wild bird such as a duck or seagull, think bird flu. Because it’s actually more likely than not they’re infected with the virus. And many species of wild birds are asymptomatic, meaning that they don’t show any symptoms. The risk of transmission to pets is low, but they can get sick from chewing or eating an infected bird, whether it’s dead or alive.

Researcher uses artificial intelligence to discover new materials for advanced computing
Researchers have identified novel van der Waals (vdW) magnets using cutting-edge tools in artificial intelligence (AI). In particular, the team identified transition metal halide vdW materials with large magnetic moments that are predicted to be chemically stable using semi-supervised learning. These two-dimensional (2D) vdW magnets have potential applications in data storage, spintronics, and even quantum computing.

A journey to the origins of multicellular life: Long-term experimental evolution in the lab
Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how snowflake yeast evolved to be physically stronger and more than 20,000 times larger than their ancestor. Their study is the first major report on the ongoing Multicellularity Long-Term Evolution Experiment (MuLTEE), which the team hopes to run for decades.

Extending the life of a lithium metal anode using a protective layer made of an extremely tough gel electrolyte
A research team has succeeded in substantially improving the cycling performance of a lithium metal battery by developing a mechanically very strong polymeric gel electrolyte and integrating it into the battery as a layer to protect the lithium metal anode. This achievement may greatly facilitate efforts to put lithium metal anodes -- a potentially very high performance anode material -- into practical use.

FDA-approved Alzheimer's drug lecanemab could prevent free-floating amyloid beta fibrils from damaging the brain
Researchers described the structure of a special type of amyloid beta plaque protein associated with Alzheimer's disease (AD) progression. Scientists showed the small aggregates of the amyloid beta protein could float through the brain tissue fluid, reaching many brain regions and disrupting local neuron functioning. The research also provided evidence that a newly approved AD treatment could neutralize these small, diffusible aggregates.

Preserving pine forests by understanding beetle flight
Researchers study the flight performance of the mountain pine beetle from a fluid mechanics and an entomological perspective. Understanding these aspects of the insect's flight could improve estimates of its spread through the environment and preserve pine forests. To examine insect flight, the team employed a type of model previously used for idealized airfoils. They showed that it can be successfully applied to multiple individual animals across biological sex, insect age, and body size. In doing so, the model can predict how these factors impact flight characteristics.

Paediatrician and geneticist determined to save the lives of children in countries where malaria is endemic
Malaria kills more than half a million people every year, mostly children under the age of five in Africa. Saving the lives of those children was the lifelong mission of Dominic Kwiatkowski, who has died suddenly aged 69.
Allied to that ambition was his vision that genetic sequencing – a technology that was beginning to be affordable on a large scale in the 2000s – could answer questions about why some children died and others survived.
