McGill University researchers found that treating peanuts with cold plasma — an ionized gas that alters protein structure — for just 25 minutes reduces allergic immune response by nearly 70%. The method preserves taste and nutrition and could be extended to eggs, hazelnuts, and other common allergens, opening the door to a wider range of safer foods.

UC San Diego researchers found that anti-vaping advertising and news coverage of the 2019 EVALI lung injury outbreak were the turning point in reversing teen vaping in the US. Among California adolescents, quit attempts nearly doubled between 2017–18 and 2019–20. Nationally, youth vaping fell from a peak of 20% in 2019 to 5.9% by 2024 — proof that public health messaging works.

L’art, la musique et la danse peuvent reconfigurer le cerveau TDAH sans médicaments

New research shows that the "defocused attention" typical of ADHD is also a powerful driver of creative thinking. Activities like art, music, dance, writing, and gaming can provide structured ways to channel this trait — and may strengthen the neural networks involved in attention control, reducing impulsivity and hyperactivity. ADHD affects nearly 8% of children worldwide.

La kératine de laine répare les os mieux que l’actuelle référence médicale

Researchers have successfully extracted keratin from wool and used it to regenerate bone in a living animal. The wool-based scaffolds produced bone that was more organized and structurally sound than collagen, the long-standing benchmark. Wool is often a by-product of farming, making the material both renewable and scalable.

Voter allonge la vie des personnes âgées, selon une étude

A University of Pennsylvania study tracked older adults who voted in the 2008 U.S. presidential election and found they had a significantly reduced risk of dying over the following 5, 10, and 15 years, with those in poorer health benefiting most. The effect held whether people voted in person or by mail, regardless of who they voted for.

Des graines de moringa filtrent les microplastiques de l’eau

Brazilian researchers have shown that a saline extract from moringa seeds — a plant native to India and common across the tropics — removes microplastics from water as effectively as aluminum sulfate, the chemical widely used in treatment plants. In alkaline water, moringa performed even better, and the extract can be prepared at home, making it a viable solution for rural communities worldwide.
