The Lancet this week features a paper calling for a financially sustainable network of influenza labs and experts across Europe. Marion Koopmans was one of the 32 expert signatures, and she describes how Europe needs to learn some lessons from the model developed previously in the US. The ongoing worries around avian H5N1 would be a great example of why funding for that sort of frontline strategic science needs not to be reliant on ad-hoc, potentially political, funding grants.

This weekend, a conference is taking place in Asilomar, CA, to mark 50 years since the 1975 conference there at which scientists developed some rules and guidelines around the future practice of genetic science. The historic Asilomar conference is celebrated by many as the moment scientists first demonstrated that they could spot risks, and self-regulate their activities, around novel and disruptive technologies. Author and scientist Matthew Cobb of the University of Manchester, and Shobita Parthasarathy of the University of Michigan discuss how perhaps other perspectives on the Asilomar legacy should be considered.

This week the recently spotted asteroid 2024 YR4 had its odds of missing us “spectacularly” slashed by 1 percentage point. Still nothing to worry about maintains Patrick Michel of the International Asteroid Warning Network, and he expects that with better tracking data in the next few months (even courtesy of the JWST) that tiny chance of collision will fall further. However, as he explains, it’s very comforting to know that we now have such a sophisticated tracking network, and even better, thanks to NASA’s DART mission, even a demonstrable method for doing something about it if the numbers go the other way…

But other extraterrestrial bombardments are harder to detect at all. This week scientists of the KM3NeT collaboration report in the journal Nature their detection of the most energetic neutrino ever noticed. Almost countless numbers travel through the earth – and us – every second, but this little beauty arrived from deep space, plummeting through hundreds of miles of rock and sea (via Malta) to collide with a single molecule of water in the Mediterranean sea. As Paschal Coyle of Aix Marseille University happens to run a cubic kilometre of neutrino observatory in that area explains their huge instrument was barely begun when the record breaker smashed through the area in February 2023.

Finally, years of breeding rice cultivars for higher yield may have subtly changed the plants relationship with the microbes in the paddies in which they grow, inadvertently boosting the amount of methane released into our atmosphere. New research, including 3 years of field trials in China have produced a new cultivar, breeding in some of the older stocks, with just as high yields yet up to 70 percent lower methane released. This could make a serious difference to global methane emissions, as Microbiologist Anna Schnürer of Uppsala BioCenter in Sweden describes.

The mystery swarm of small earthquakes near the island of Santorini beg for more data collection. Also, the National Oceanic and Atmospheric Administration (NOAA) in the US goes offline and whales learn song like kids learn language.

Nasa's OSIRIS-REx mission to collect a sample from an asteroid has been a great success. Asteroid Bennu's sample yields a watery pool of history, thanks to an international team of scientists including the London Natural History Museum's Sarah Russell.

Also, in a week of tumultuous changes to federal funding and programmes, we hear from some US scientists affected and concerned by Executive Orders from the White House. Betsy Southwood, formerly of the Environmental Protection Agency, is worried not just about the government employees’ careers, but the environment itself and the whole of environmental science in the US and the world. Chrystal Starbird runs a lab at the University of North Carolina and is worried about the fate of grants aimed at diversifying scientific expertise, but also that some grant schemes are getting erroneously included in the anti-DEI clampdown. And Lawrence Gostin is an eminent health lawyer, proud of the NIH and all it has achieved.

Thirty per cent of the Arctic is switching from carbon sink to carbon source. But could future fertilizer be made deep underground using less resources? Also, how and perhaps why globally 2024 had the highest number of fatal landslides in over 20 years, and an unexpected sound from space prompts a re-evaluation of how the earth’s magnetic field interacts with the environment around it.

New types of snake-bite anti-venoms are designed by AI. Also, how much meat did human ancestors eat? How the Baltic Nord Stream gas pipeline rupture of 2022 was the biggest single release of methane ever caused by humans, and that Pluto met Charon, not with a bang, but more of a kiss.

Using a high precision technique for spotting different isotopes of Nitrogen, Tina Lüdecke of the Max Planck Institute for Chemistry has concluded that a group of early hominin Australopithecus living in South Africa were predominantly vegetarian, putting the date that human ancestors started eating meat (and thence growing bigger brains) to more recently. The technique, she thinks, can enlighten prehistoric food webs and ecologies from millions of years ago.

Last year’s Nobel prizes showed the potential new techniques of AI to design synthetic proteins. Timothy P Jenkins and colleagues decided to try designing treatments for snakebite venoms, with remarkable apparent success. It could save many thousands of lives a year.

Since the September 2022 explosions at the Nord Stream gas pipeline in the Baltic sea, many different analyses of how much methane was released have provided a variety of estimates. This week, scientists at the UNEP International Methane emissions observatory – including Stephen Harris - published a study estimating it to be a little under half a million tonnes, making it by far the single biggest human caused release of this most dangerous greenhouse gas. Yet, they say, even that is a tiny fraction of what is released overall around the world every year.

And Finally, a new analysis of the original formation of the Pluto-Charon binary Dwarf Planetary system suggests they – and possibly many other Kuiper belt pairing – were born of a gentle astronomical dance and a peck on the cheek, rather than the catastrophic collision we associate with the earth-moon’s fiery first date. And it may have lasted just a matter of days, according to author Adeene Denton of the University of Arizona.

H5N1 bird flu is still spreading across farms in the USA and this week claimed its first human life in North America - an elderly patient in Louisiana infected by backyard poultry. But last week, Sonja Olsen, Associate Director for Preparedness and Response in the CDC’s flu division, and her colleague Shikha Garg, published new analysis in the New England Journal of Medicine summarizing the human cases and epidemiology so far.

A lab study underscoring a suspected link between the virus responsible for cold sores, and Alzheimers, the most common form of dementia, has been published in Science Signalling this week. The study, by Dana Cairns of Tufts University, looks at whether repetitive brain trauma – another risk factor - adds to the evidence that latent herpes simplex can be involved.

Song Lin, a chemist at Cornell University who has won prizes for pioneering the use of electrical currents to drive chemical reactions rather than heat, has teamed up with Cornell micro engineer Paul McEuen to power up a new kind of chemistry and invent another kind of SPECS – an acronym for Small Photoelectronics for Electrochemical Synthesis. They outlined their first generation device and the promises it brings in Nature this week.

Sars CoV-2 has been with us for five years. In the second of a 2-part special, Science in Action asks how well was science prepared for it? And are we any better prepared for the next one?

New insights into how our skin learns to tolerate and co-exist with bacteria on its surface show great potential for the development of simpler and less invasive vaccines. Stanford University’s Djenet Bousbaine has published two papers in Nature detailing the microbiological research and mouse vaccination experiments that could change the future of immunisation.
