C’est une découverte astronomique, au premier sens du terme : des chercheurs viennent en effet d’identifier ce qui pourrait bien être le plus vaste océan jamais observé, soit un monumental réservoir d’eau situé autour du quasar APM 08279+5255, à plus de 12 milliards d’années-lumière de la Terre. L’étendue …

In a major breakthrough, scientists can now extract DNA from sediment instead of relying on bones

Cristina Dorador is on an urgent mission in the world’s highest desert, the Atacama in Chile. As the rise of drug-resistant superbugs kills millions per year, Cristina has made it her mission to uncover new, life-saving antibiotics in the stunning salt flats she has studied since she was 14. Against the magnificent backdrop of endless plains, microscopic discoveries lead her team of scientists to question how critically lithium mining is damaging the delicate ecosystem and impacting Indigenous communities

Durant le Miocène moyen et supérieur (12,4 à 5,3 millions d’années), des animaux géants peuplaient – et rampaient sur – la Terre grâce à des températures plus chaudes, des zones humides étendues et une nourriture abondante. Nombreux de leurs descendants actuels sont significativement plus petits, mais les anacondas (Eunectes) se révèlent obstinément réfractaires à cette ... Lire plus

Researchers urge public not to handle stranded sea snakes as they are highly venomous

Conch-shell trumpets discovered in Neolithic settlements and mines in Catalonia make tone similar to french horn, says lead researcher

As a child, Miquel López García was fascinated by the conch shell, kept in the bathroom, that his father’s family in the southern Spanish region of Almería had blown to warn their fellow villagers of rising rivers and approaching flood waters.

The hours he spent getting that “characteristically potent sound out of it” paid off last year when the archaeologist, musicologist and professional trumpet player pressed his lips to eight conch-shell trumpets. Their tones, he says, could carry insights into the lives of the people who lived in north-east Spain 6,000 years ago.

Artificial intelligence can execute tasks in seconds that once took humans hours, if not days to complete. While this may be great for productivity, some researchers are concerned that our increasing use of AI could be impacting our ability to tackle difficult problems and think critically. To find out where the science stands, and how worried we should be about the potential of AI to change how we think, Ian Sample hears from Madeleine Finlay and Sam Gilbert, professor of neuroscience at University College London

WHO urges countries to make drugs such as Mounjaro more accessible to people and asks drugs companies to lower prices

Weight loss drugs such as Mounjaro offer huge potential to tackle soaring obesity globally but are currently only available to one in 10 of those who need them, the World Health Organization has said.

Their proven effectiveness in helping people lose weight means the medications represent “a new chapter” in how health services can treat obesity and the killer diseases it causes, the WHO added.

Bien plus qu’un simple compagnon du petit-déjeuner, le jus d’orange pourrait influencer des mécanismes biologiques essentiels. Une nouvelle étude révèle que cette boisson courante agit directement sur l’expression de milliers de gènes liés à l’immunité, à l’inflammation et à la régulation cardiovasculaire, suggérant un impact largement sous-estimé sur la santé métabolique et le cœur.
