Hello Nature readers, |

| An abnormal form of a protein called tau begins to accumulate in the brains of people with Alzheimer’s disease well before symptoms such as memory loss appear. (Alfred Pasieka/Science Photo Library) | ||||||
Blood test could predict Alzheimer’s onsetA simple blood test that measures the levels of an abnormal form of the protein tau’ might one day serve as a molecular ‘clock’ that predicts not only whether someone will develop Alzheimer’s disease — but when. If validated in larger studies, the test could provide a way to intervene in the neurodegenerative disease at an earlier stage, when treatment is more likely to be effective. It could also provide a measurable biological marker, or ‘biomarker’, to make clinical trials of potential Alzheimer’s disease treatments easier and cheaper. Nature | 5 min read |

Nasal vaccine fends off multiple pathogensA nasal-spray vaccine can provide mice with protection from a variety of bacterial and viral pathogens — including SARS-CoV-2 — and respiratory allergens for at least three months. The vaccine works by revving up the innate immune system, which has a much broader reactivity than does the adaptive immune system — the one conventional vaccines utilize. If the spray proves safe and effective in humans, such a ‘universal vaccine’ could be offered to everyone at the start of each winter — and perhaps provide a first line of defence against future pandemics.

Biotech investor set to lead NSFUS President Donald Trump plans to nominate biotechnology investor Jim O’Neill to be the next leader of the National Science Foundation (NSF), a White House spokesperson confirmed to Nature. If confirmed by the Senate, O’Neill would become the first non-scientist or engineer to lead the NSF, which has been without a director since April 2025. “His background is very different from that of his predecessors,” says former NSF director Neal Lane. “That will be a major concern of the [science and technology] community.” |

QUESTION OF THE WEEKEarlier this week, we read about RentAHuman.ai, a platform on which artificial-intelligence agents can hire human workers to complete tasks that require a physical body on their behalf, such as attending meetings or taking photographs. So far, no publicly available tasks that have been posted by AI agents request specific jobs for people with science or research skills. But a handful of scientists have created profiles to offer their services, mentioning skills in mathematics, physics, computer science, immunology and biology. So, what about you — would you accept paid work from an AI agent if one required the use of your research skills?

How militarization could change scienceAround the world, many countries — notably China, the United States and other members of NATO — are increasing their defence and security budgets. But nations have considerable leeway to decide what to fund with these pots, which can include research and development funding. Backed by bigger military budgets, science is likely to become more constrained by ideas of national self-interest, say experts, with collaborations decreasing or realigning to within regional blocs. Shifting funding priorities will also disproportionately benefit certain fields, such as artificial intelligence, while others, such as climate science, might be left behind, they say. |

Podcast: big data; little glass tileA team of scientists at Microsoft have created a data-storage system that uses lasers to etch information into glass. These glass tiles, roughly the size of a DVD, could keep terabytes of data safe for around 10,000 years or more. With this method, “there’s no or very little ongoing cost as a result of keeping the data”, says computer scientist Richard Black, who led the project. “It means that once you decide to keep something, there’s almost no reason to ever delete it.” Nature Podcast | 21 min listen |

QUOTE OF THE DAY“You’re no longer ‘deciding’ to laugh. The system has taken over and you’re helpless.”Anatomist Michelle Spear explains what drives laughter, and why it’s so hard to suppress in formal settings where it could be deemed inappropriate. (The Conversation | 5 min read) |
