Study of twins detects bacteria in the small intestine that play a role in the development of MS To the point Twin study : Among many other factors, microorganisms in the gut are suspected of contributing to the onset of MS. To obtain meaningful results, researchers examined stool samples and microorganisms directly from the small intestine of identical twins, where only one twin had MS.

A new class of molecules capable of killing the cancer cells that are refractory to standard treatments and responsible for recurrence has just been developed by scientists at Institut Curie, the CNRS, and Inserm. This crucial advance in the fight against metastatic cancer is based on identifying the cellular site for ferroptosis initiation, a natural process, catalysed by iron, that sparks the oxidative degradation of cell membranes.

Study suggests that combining hockey scouts' judgements with objective testing could help identify the players with the best 'game sense' In a study that is the first of its kind, a research team led by a McGill professor has developed a more objective way to identify ice hockey players' game intelligence, or "hockey IQ.

ISTA scientists present new microscopy method to reconstruct mammalian brain tissue Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this complicated network requires a precise look into how these nerve cells are arranged and connected.

Agriculture's impact on insect diversity is more severe than previously thought, according to a new study from the Julius-Maximilians-Universität Würzburg. It has long been known that agriculture contributes to the decline in insect biodiversity. The loss of host plants, frequent mowing, and pesticide use all deprive many species of their habitats.

To the point Complex communication: Researchers studying the social networks of monk parakeets in Spain uncovered a link between an animal-s social ties and the calls that it makes. Levels of sociality: They spent two years recording the social lives, as well as all screeches, squawks and whistles, of over 300 parrots-linking what individuals say to very specific levels of sociality.

A study by EPFL and the Swiss Federal Food Safety and Veterinary Office (FSVO) has found that tire additives enter into and pass through the food chain. Further research is needed to establish the implications for human health. Traces of the additives typically used in tire manufacturing have been detected in all'of the most common types of fruits and vegetables eaten in Switzerland.

Breakthrough achieved by UC3M and Harvard scientists A team of scientists from Universidad Carlos III de Madrid (UC3M) and Harvard University have experimentally demonstrated that it is possible to reprogram the mechanical and structural behaviour of innovative artificial materials with magnetic properties, known as metamaterials, without the need to modify their composition.

New property of graphene revealed by ultra-clean airless measurement Environment Graphene is a "miracle material": mechanically extremely strong and electrically highly conductive, ideal for related applications. Using a worldwide unique method physicists at the University of Vienna led by Jani Kotakoski have for the first time made graphene drastically more stretchable by rippling it like an accordion.

Results from a long-term field experiment shed new light on how grasslands can be restored for nature, the environment, and for farmers. From richer biodiversity and benefits for pollinators, to carbon storage in soils, while balancing hay yields for grazing livestock, the study published in Nature Communications by researchers at The University of Manchester and Lancaster University, in collaboration with the Universities of Yale and Bergen, shows that using combinations of different restoration techniques can markedly enhance the restoration of grasslands.

An international team of scientists led by the Medical University of Vienna has identified similarities in the mechanisms of diabetes and cancer: as the researchers show, the protein PPAR', which is central to the regulation of metabolic processes, can also influence the growth of prostate cancer cells.

A new website offers video capsules and popular texts to inform the general public about the scientifically recognized benefits of playing and listening to music You don't have to be a violin virtuoso or a guitarist of the calibre of Jimi Hendrix to enjoy the benefits of music. Every amateur musician benefits from playing an instrument, even if it's just a few notes or a wooden spoon.

Bonn researchers develop method for describing and predicting critical transitions in networked systems The global climate is in an imbalance. Potential "tipping elements " include the Greenland ice sheet, coral reefs, and the Amazon rainforest. Together they form a network that can collapse if just one individual component tips.

Alessandro Ingrosso, researcher at the Donders Institute for Neuroscience, has developed a new mathematical method in collaboration with colleagues in two Italian research institutions, which enables the prediction of the effectiveness of transfer learning in neural networks. T he problem of limited data AI systems are typically trained with large amounts of data.

In just 15 minutes, training with a simulator enabled professional field hockey players to significantly improve their perceptive skills in front of the opposing net. This new approach, developed by researchers at the University of Fribourg's Perception and Control Laboratory, enables players to better and more quickly identify the area of the goal least covered by the goalkeeper.

The use of animal manure in agriculture appears to be the best choice in terms of metal contamination of our soils Metals and hormone-disrupting substances such as oestrogens present a genuine risk to the sustainability of agriculture and water management in Europe. This is the conclusion of doctoral research conducted by Chinese environmental scientist Yuwei Jia at the Vrije Universiteit Brussel (VUB).

Adolescents with mental health conditions use social media differently than their peers, study suggests One of the first studies in this area to use clinical-level diagnoses reveals a range of differences between young people with and without mental health conditions when it comes to social media - from changes in mood to time spent on sites.

Characteristic depressive episodes are the most common mental disorders worldwide. One in five people will suffer from depression in their lifetime, with suicidal risk responsible for several thousand deaths a year in France.

An alloy of aluminum, magnesium and scandium is strong and does not become brittle even when exposed to relatively large amounts of hydrogen Aluminum alloys are known for their light weight and corrosion resistance - properties that make them ideal materials for a CO2-free economy. Whether in the lightweight construction of vehicles or as storage tanks for green hydrogen, the demand for aluminum will continue to increase with the transition to sustainable technologies.

A technical trick has been used to simulate a speed of light of only 2 m/s in the laboratory. This made it possible to reproduce the relativistic Terrell-Penrose effect for the first time. When an object moves extremely fast - close to the speed of light - certain basic assumptions that we take for granted no longer apply.
