    BANISHING TOOTH PLAQUE TO BOOST ORAL HYGIENE

    a1-a2页
    查看更多>>摘要：Periodontal disease is common around the world, with the World Health Organization classifying it as a major public health problem due to its high prevalence and links to systemic chronic conditions, such as cardiovascular diseases, diabetes and respiratory illnesses. In China, the burden is particularly acute. A combination of poor oral hygiene, high tobacco use, issues with nutrition and limited access to preventive dental care, means that gum disease strikes early and frequently. Among adults aged 25 to 44 years old, around 87% have bleeding gums, and 97% had calculus buildup - both early signs of gum disease.

    Without science, there can be no development

    607-607页
    查看更多>>摘要：Two weeks ago, world leaders met in sweltering heat in Seville, Spain, for the fourth International Conference on Financing for Development, sponsored by the United Nations. What might sound dry and technocratic is anything but, with implications for lives, health and well-being. The lack of funding for vaccines for the poorest countries, the need to provide more funding to build and improve primary schools and to protect people from climate-induced extreme weather all affect hundreds of millions of people.

    How to de-Americanize global science

    Joao Conde
    609-609页
    查看更多>>摘要：The United States has for decades been a great benefactor of global science. Last year, the US National Institutes of Health (NIH) awarded hundreds of grants to researchers outside the country. In 2022-23, the country supplied about 42% of the overall donor-government assistance for global health and about 16% of the World Health Organization's (WHO) funding. During the COVID-19 pandemic, it bankrolled a fair share of the global public vaccine effort.

    Bring science into business schools

    Matthew Agarwala
    610-610页
    查看更多>>摘要：Thisyear has seen a stunning collapseof ambition when it comes to assuring a sustainable future. Populism, short sightedness and scientific ignorance deserve blame. But so do the cost-of-living crisisand deepening inequality; environmental goals are often the first casualty of economic stagnation. Governments and businesses should know better. Nature loss, volatile energy prices and air pollution all undermine productivity. Fail to address such issues and the resulting spiral will be vicious. So why is the business case for protecting nature not stronger? Or at least more familiar, made more forcefully, more regularly and by more captains of industry?

    Research highlights

    611-611页
    查看更多>>摘要：Exercise helps the immune system to fight tumours by stimulating microbes in the gut to make a compound known as formate, studies in mice have shown. Exercise is known to boost the effectiveness of cancer drugs called immune checkpoint inhibitors, which unleash the immune system against tumours. To find out how it does this, Catherine Phelps at the University of Pittsburgh School of Medicine in Pennsylvania and her colleagues studied how running on a treadmill affected mice with skin cancer.

    CHINA POURS MONEY INTO BRAIN MIPS THAT GIVE PARALYSED PEOPLE IMPROVED CONTROL

    Smriti Mallapaty
    613-614页
    查看更多>>摘要：A deep-brain device that allowed a man with no limbs to play computer games is one of an increasing number of brain-computer interfaces (BCIs) being trialled in people in China. The BCI system, developed by medical-technology company StairMed in Shanghai, China, is similar to the implants being trialled in people by Neuralink, owned by Elon Musk, based in Fremont, California. StairMed'sdevice has fewer probes than Neuralink's device has, but it is smaller and less invasive.

    SLEUTHS SAY THEIR WORK IS BEING TWISTED' TO UNDERMINE SCIENCE

    Miryam Naddaf
    615-616页
    查看更多>>摘要：For years, scientific sleuths have been uncovering flaws and fraud in research publishing, from duplicated images and fabricated data to fake peer reviews. Their work has helped to bring about the retraction of problematic papers and changes to editorial policies. But now, say several prominent sleuths, their findings are increasingly being used out of context, to argue that science itself is broken.

    BOOSTED KILLER' CELLS SHOW PROMISE FOR AUTOIMMUNE DISEASE

    Heidi Ledford
    616-617页
    查看更多>>摘要：Supercharged 'natural killer' cells could become a potent way to reset a disordered immune system - and thus quench some autoimmune disorders. Results from two small clinical trials suggest that researchers can engineer natural killer cells-immune cells that destroy infected or diseased cells - to assassinate the renegade cells that produce antibodies against the body's own tissues. These 'autoantibodies' can damage tissues, fuelling autoimmune diseases such as lupus and systemic sclerosis.

    OPENAI MODEL TOPS NEW Al LEAGUE TABLE FOR SCIENCE QUERIES

    Rachel Fieldhouse
    617-618页
    查看更多>>摘要：An artificial intelligence (Al) model called o3, developed by the creators of ChatGPT, has been ranked the best Al tool for answering scientific questions in multiple fields, according to a benchmarking platform launched on 30June. SciArena, developed by the Allen Institute for Artificial Intelligence (Ai2) in Seattle, Washington, ranked 23 large language models (LLMs) according to their answers to scientific questions. The quality of the answers was voted on by 102 researchers. o3, created by OpenAI in San Francisco, California, was ranked the best at answering questions on natural sciences, health care, engineering and humanities and social science, after more than 13,000 votes.
