Covering current events in science, the environment, technology and health requires a context and reliable sources that respond quickly.
When science hits the headlines, we publish reactions, explanations, and in-depth analysis from reliable sources, capturing both the evidence and the debates. Our library of science journalism resources and the briefings may be of use to you. Consult our directory of research centres.
We are on the lookout for any controversial information about science (embargoed or not), in order to react with the agility the media needs. Sign up to receive our embargoed contents, all under the Creative Commons licence. Find out more about how we work here.
Abandoned farmlands in Europe could find new life through rewilding, a movement aimed at restoring devastated landscapes to their wild state before human intervention. A quarter of the European continent, 117 million hectares, is ready for rewilding, according to a study published today in the journal Current Biology.
Sweden's public health agency issued a statement on Thursday indicating that a person has been diagnosed with mpox - formerly called monkeypox - caused by variant clade I. According to the Swedish agency, this is the first case of this variant to be diagnosed outside the African continent. The person would have been infected during a stay in a part of Africa where there is an outbreak of this variant of mpox, according to the statement. The announcement comes a day after the World Health Organisation declared the mpox outbreak a public health emergency of international concern.
An international team of researchers has studied 241 brain-damaged people apparently unable to respond to external stimuli. Using techniques such as functional magnetic resonance imaging and electroencephalogram, they have detected signs of brain activity in 25 % of them that, according to the authors, ‘suggest that they may be interacting with the outside world’. The results are published in the journal NEJM.
A ketogenic diet improves the results of a pancreatic cancer therapy in mice, according to a study published in Nature. The US research team fed the animals a high-fat, low-carbohydrate diet before administering them a new drug, currently in clinical trials; in the absence of glucose, the body converts fat into ketone bodies. The drug blocks the metabolism of fat - the cancer's only source of energy while the mice are on this diet - and slows the growth of pancreatic tumours.
The impact of animal abandonment goes beyond the pets who suffer it, it is a public health, safety and funding issue as well. Although there have been some improvements in recent years, the experts consulted agree that the system continues to fail. In this guide, we analyze what has changed, who does this issue affect, and what must be improved.
Heat-related mortality in Europe would have been 80% higher last year without recent adaptation measures to rising temperatures, such as changes in infrastructure and public behaviour, according to a study led by ISGlobal. The study, published in Nature Medicine, estimates that more than 47,000 deaths were related to the heat in 35 European countries in 2023 - the second highest number in the 2015-2023 period, behind 2022. Heat-related mortality was highest in southern European countries including Spain (175 deaths per million people), Italy (209) and Greece (393).
Summer is a season of beaches, pools, excursions, trips, and mountain hikes. But it is also the best time of the year for bedbugs, wasps, jellyfish, and mosquitoes. With this guide, we will know what to do (and not to do) if we have an undesirable encounter with one of these animals: the first step, stay calm.
A brain study of 23 people with treatment-resistant depression while they listen to classical music has identified the antidepressant mechanisms of this music. Using intracranial recordings and electroencephalogrammes, the researchers concluded that listening to classical music synchronises neuronal oscillations between the auditory cortex - responsible for processing sensory information - and the reward circuit - responsible for processing emotional information. "The improvement of depressive symptoms was not linked to the emotion of the music itself but was correlated with the patient’s level of music enjoyment," says the study published in Cell Reports.
Scientists in Hong Kong have studied the usefulness of six indices that estimate the severity and health hazard of a heatwave. Analysing several episodes in recent years in Spain, India and the United States, they conclude that five of the six were not able to capture their severity and spatial distribution effectively enough, especially in low humidity conditions. The most useful was the so-called "lethal heat stress index", but the researchers - publishing their results in the Cell group's journal Nexus - say that it too can be improved and that a more global framework is needed to mitigate dangerous heatwaves.
A team of researchers has analysed data from more than 650,000 residents in Sweden and concluded that the genetic predisposition of peers - especially in high school - influences one's risk of developing anxiety, depression or drug abuse in the future. According to the authors, who publish the results in the American Journal of Psychiatry, this relationship appears "even after controlling statistically for whether peers were affected or not".
