Community speaks up for science in the UK culture wars
Last month I coordinated an open letter to the UK prime minister and the UK secretary of state for science, innovation and technology (go.nature.com/47exuxk), which directly challenges their vow to banish “the slow creep of wokeism” and “political correctness” from science (go.nature.com/3twjxdx). Competing Interests The author declares no competing interests.

Investigation of N-polar InGaN growth on misoriented ScAlMgO4 substrates
Abstract We report the growth of N-polar InGaN layers on misoriented ScAlMgO4 (SAM) substrates with offset of 0.3 to 5.8° toward the m-plane. The surface of N-polar InGaN with small-offset substrates exhibited hexagonal hillocks similar to those commonly observed in N-polar GaN layers. Larger misorientation angles resulted in smoother surfaces of the InGaN layers. In…

Lower serum testosterone is associated with increased likelihood of arthritis
Abstract Studies have suggested that serum testosterone levels may be strongly correlated with the pathogenesis of arthritis. Therefore, the aim of this study was to assess the relationship between serum testosterone levels and arthritis in US adults using the National Health and Nutrition Examination Survey (NHANES). We used the database from NHANES, 2013–2016 to perform…

Israel: when reality meets academia
On 7 October, thousands of Hamas terrorists invaded southern Israel, killing at least 1,400 people and kidnapping more than 240 civilians. These include fellow faculty members, postdocs and students who are dead, wounded or still missing. Along with many other academics, we have been vocal advocates of greater liberalism in Israel (see E. Albin et…

Nobel win: spotlight on the attrition of women in science
Katalin Karikó’s joint win of this year’s Nobel Prize in Physiology or Medicine helps to redress the history of gender bias in Nobel awards (see Nature 622, 228–229; 2023). Yet her achievement is not so much a win for female researchers as a warning of how much is being lost through the continued attrition of…

Dentinomimetics and cementomimetics of Moringa oleifera leaves extract
Abstract To evaluate the biomimetic remineralization capabilities of Moringa oleifera leaves (MOL) extract on coronal dentin and acellular cementum, two different concentrations (50 and 200 mg/ml) of MOL extract loaded in plain varnish (M1 and M2 groups respectively) were compared to fluoride varnish (FL group) and native surface (C group). Eighty sound premolar teeth were collected.…

How AI could lead to a better understanding of the brain
Can a computer be programmed to simulate a brain? It’s a question mathematicians, theoreticians and experimentalists have long been asking — whether spurred by a desire to create artificial intelligence (AI) or by the idea that a complex system such as the brain can be understood only when mathematics or a computer can reproduce its…

Nature retracts controversial superconductivity paper by embattled physicist
Physicist Ranga Dias is under investigation by his institution, the University of Rochester in New York.Credit: Lauren Petracca/New York Times/Redux/eyevine Nature has retracted a controversial paper1 claiming the discovery of a superconductor — a material that carries electrical currents with zero resistance — capable of operating at room temperature and relatively low pressure. Why a…

Croaking Frogs, Buzzing Hornets, Squealing Dolphins: A Guide to Smithsonian Folkways’ Best Science and Nature Recordings
We’re always finding ways to capture and learn from the sounds around us: Recordings of melting ice assist in tracking the rate of climate change; hydrophones eavesdropping on underwater insects help measure the health of the ecosystem; and astronomers even figured out the pitch of a massive black hole—B flat, it turned out—in order to…
