Reaction: International Athletics Federation bans transgender athletes from competing in women's competitions

The International Athletics Federation has decided to ban transgender athletes who have transitioned after puberty from participating in international women's competitions. Although there are currently no trans athletes competing on the international circuit, the Federation "decided to prioritise the fairness and integrity of women's competition before inclusion", according to the statement issued. At a press conference, its president, Sebastian Coe, said: "We will be guided by the science that will inevitably develop in the coming years around physical performance and male advantage. As more evidence becomes available, we will review our position.

Reaction: meta-analysis finds lack of scientific evidence on efficacy and safety of painkillers for low back pain

A meta-analysis analysing 98 published clinical trials highlights the lack of scientific evidence on the efficacy and safety of commonly used analgesic drugs for acute low back pain (such as anti-inflammatory drugs, paracetamol and opioids, among others). The study, published in The BMJ, includes data from more than 15,000 people. It concludes that there is "considerable uncertainty" about the efficacy of these drugs in reducing the severity of non-specific acute low back pain and calls on doctors and patients to use them with caution.

Reaction: new technique allows sperm to be selected for sex selection

Researchers in the United States have tested a new technique to select sperm and thereby increase the chances that the embryo will be of either sex. The proven efficacy is around 80 %. Although some countries such as the United States allow this type of procedure, in Spain it is prohibited except in cases of prevention of diseases linked to sex chromosomes. The authors of the article state that sperm selection is more ethically acceptable than embryo selection. The results are published in the journal PLOS ONE.

Reactions: Luis A. Caffarelli wins the Abel Prize, the Nobel Prize in Mathematics, for his contributions to the regularity of partial differential equations

The Norwegian Academy of Science and Letters has awarded the Abel Prize to Luis A. Caffarelli, a native of Argentina with US-Argentine nationality, for his "fundamental contributions to the theory of the regularity of nonlinear partial differential equations". Considered the Nobel Prize of mathematics, the award recognises work over an entire career - unlike the Fields Medal, which is awarded for a result under the age of 40. Caffarelli has become the first Latin American to receive this award.

Reactions to the discovery of an RNA component on the asteroid Ryugu

A Japanese research team has announced in Nature Communications that it found uracil, a component necessary to form RNA, in a small sample collected from the asteroid Ryugu. According to the authors, these results indicate that these molecules of prebiotic interest were commonly formed on asteroids like Ryugu, and reached the early Earth with the impact of these bodies. The sample was collected by the Japan Aerospace Exploration Agency's Hayabusa2 robotic spacecraft, which returned to Earth in December 2020.

Reaction: minimum alcohol pricing reduces alcohol-related deaths

In 2018, a regulation was introduced in Scotland that establishes a minimum sale price for alcoholic beverages, proportional to the amount of alcohol they contain. A study has analysed the health impact of this measure. According to the authors, alcohol-related mortality has decreased by 13% since then, especially among the most disadvantaged socio-economic classes. The results are published in the journal The Lancet.

Reactions: two articles denounce the impact of space debris and near-Earth satellites on the night sky

Space debris and satellites orbiting close to Earth have proliferated in recent years. Two articles in Nature Astronomy warn of their impact on light pollution. In the first, a team calculates the increase in the brightness of the night sky and warns of the effect on ecosystems and astronomical observations from Earth. In the second, which is a commentary, the authors call for limiting the production of artificial light and the number of satellites in orbit, calling on the scientific community to take on the big space and big light companies. Both articles are co-signed by Salvador Bará, from the Agrupación Astronómica Coruñesa, and the second by Fabio Falchi, from the University of Santiago de Compostela.

Reactions to the IPCC synthesis report urging more ambitious action to combat climate change

Almost a decade after the previous edition, the Intergovernmental Panel on Climate Change (IPCC) has presented the synthesis report of its sixth assessment cycle (AR6) on Monday in Switzerland. "This synthesis report underlines the urgency of taking more ambitious action and demonstrates that, if we act now, we can still secure a sustainable and liveable future for all," said IPCC chair Hoesung Lee. 

The document includes the main findings of the three Working Group reports of 2021 and 2022 (Physical basis, Impacts, adaptation and vulnerability and Mitigation of climate change) and the three special reports of 2018 and 2019 (Global warming of 1.5°C, Climate change and land, Ocean and cryosphere in a changing climate). With this document, which is primarily addressed to policy makers, the IPCC closes its sixth assessment cycle.

Reaction: new data show that animals susceptible to SARS-CoV-2 infection were present at the Wuhan market

A French researcher has found genetic data showing that raccoon dogs, civets and other mammals susceptible to the infection with SARS-CoV-2 in the early 2020s in the Wuhan market in China. The findings have been presented to the Scientific Advisory Group on the Origin of Emerging Pathogens (SAGO), an expert group convened last year by the World Health Organisation. The data, collected by a team of Chinese scientists, were held in a database called GISAID, but had not been publicly reported and have been withdrawn. SAGO explained the origin of this data and the history of this research in a statement on 18 March.

Reactions: study suggests elite footballers more likely to develop dementia

Swedish research involving more than 6,000 male footballers in the country's top division (between 1924 and 2019) indicates that they were 1.5 times more likely to develop a neurodegenerative disease compared to the population analysed who were not involved in professional football. Unlike outfield players, goalkeepers did not have this increased risk, which, according to the authors, supports the hypothesis that impacts to the head when striking the ball could explain the increased risk. The study is published in The Lancet Public Health.
