    Why retractions data could be a powerful tool for cleaning up science

    581-581页
    查看更多>>摘要：Many universities and research institutions around the world prize high productivity. They encourage researchers to publish more articles and accrue more citations; higher counts can signal that an institution's research is impactful and push its international ranking up. Overall, most published articles and citations represent reliable contributions to the scientific record. But in some cases, the push for more, faster research comes at a cost: it can encourage sloppy science, plagiarism and research falsification and fabrication.

    Celebrate women's achievements in science and technology

    582-582页
    查看更多>>摘要：Last week, three outstanding researchers were recognized with prizes to advance their work by the inaugural Sony Women in Technology Award with Nature. Each won US$250,000 to support and accelerate their technology-focused research. Kiana Aran, a bioengineer at the University of California, San Diego, was given a mid-career award for her work, which is at the intersection of biology, artificial intelligence (AI), electronics and materials science, investigating the use of fingertip sensors to detect genetic and viral diseases. She has also established a non-profit organization that mentors women in engineering.

    Research highlights

    585-585页
    查看更多>>摘要：A painstaking analysis of land-plant evolution has revealed how to engineer crops that produce a popular antioxidant supplement. Coenzyme Q is crucial for the proper function of cells' energy-producing structures, called mitochondria, and some people take the molecule as a supplement to improve heart health.Jing-JingXu at the Chinese Academy of Sciences in Shanghai and her colleagues studied coenzyme Q biosynthesis in 134 species from 67 land-plant families. They found that many crop species, including wheat and rice, produce a form of coenzyme Q called CoQ_9. Humans and some other plants make a different version: CoQ_(10).

    THESE GAZA SCIENTISTS ARE KEEPING RESEARCH ALIVE AMID WAR, DESTRUCTION AND UNCERTAINTY

    Michele Catanzaro
    587-588页
    查看更多>>摘要：The 42-day ceasefire between Hamas and Israel, which took effect on 19 January, is providing a vital opportunity to begin to address the devastation from the 15-month war, scientists there have told Nature. The ceasefire might yet prove temporary, and whether or not it holds, the long-term future for the territory and its citizens remains highly uncertain.

    DEEPMIND AI CRUSHES MATHS PROBLEMS ON A PAR WITH TOP STUDENTS

    Davide Castelvecchi
    589-589页
    查看更多>>摘要：A year ago, AlphaGeometry, an Al problem solver created by Google DeepMind, surprised the world by performing at the level of silver medallists in the International Mathematical Olympiad (IMO), a prestigious competition that sets tough maths problems for gifted high-school students. The DeepMind team now says the performance of its upgraded system, AlphaGeom-etry 2, has surpassed the level of the average gold medallist. The results are described in a preprint posted on the arXiv server.

    Smriti Mallapaty
    589-590页
    查看更多>>摘要：On 30 January, bioinformatician Niema Moshiri received a late-night message from a long-time collaborator urging him to back up the website of the US Centers for Disease Control and Prevention (CDC). At the time, rumours had been circulating that the public-health agency, which tracks disease outbreaks and makes its data publicly available, would start removing pages from its website, in response to executive orders issued by President Donald Trump directing government departments to take down public information on gender and diversity.

    CENTURIES OF ISOLATION SHAPED GREEN LANDERS' UNIQUE GENETICS

    Freda Kreier
    590-591页
    查看更多>>摘要：An analysis of the genomes of nearly 6,000 Greenlandic people suggests that their Inuit ancestors rarely moved around after settling the island around 1,000 years ago. This historical isolation means that people from some parts of Greenland are more likely to develop certain genetic diseases than are people in other parts of the world.

    EARTH'S MYSTERIOUS INNER CORE REALLY IS CHANGING SHAPE

    Alexandra Witze
    593-594页
    查看更多>>摘要：Earth's inner core is changing shape, scientists have found. The discovery resolves a long-running controversy about what's happening at the heart of the planet - which was long thought to be solid and unyielding. But it also raises new questions about how changes in the core could affect the length of our 24-hour day, Earth's magnetic field and more. "After decades of research and, debates, we are coming to an ever-clearer picture of the changing inner core," says Xiaodong Song, a seismologist at Peking University in Beijing, who was not involved in the work.
