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.

Treatment with gabapentinoids, a class of epilepsy and anxiety drug, is not directly associated with an increased risk of self-harm, finds a study led by UCL researchers. However, rates of self-harm were higher before and shortly after treatment, highlighting the need for close monitoring of patients throughout their treatment journey, say the authors of the new study.

Scientists from The University of Manchester have changed our understanding of how cells in living organisms divide, which could revise what students are taught at school. In a Wellcome funded study published today (01/05/25) in Science - one of the world's leading scientific journals - the researchers challenge conventional wisdom taught in schools for over 100 years.

The intensification of existing farmland can sometimes be more harmful to local biodiversity than expanding the area covered by agricultural land, finds a new study led by UCL researchers. They showed that neither expansion nor intensification is consistently better for biodiversity, as it varies by factors including region, crop type and local vegetation.

By adding a sound-mediated way to control light to the toolkit of light-based chips, University of Twente researchers have pushed the boundaries of the technology. This opens up the possibility of making atomic clocks small enough to fit in satellites and drones, helping them navigate without GPS. Imagine having to find your way with only a compass and the stars and being handed a GPS.

McGill researchers develop practical new tool for detecting nanoplastics and microplastics in the environment A team of McGill researchers has developed a cost-effective, high-throughput technology for detecting nanoplastics and microplastics in the environment. These particles are pervasive, posing health and environmental risks, yet detecting them at the nanoscale has been difficult.

The marine worm Ramisyllis multicaudata , which lives within the internal canals of a sponge, is one of only two such species possessing a branching body, with one head and multiple posterior ends. An international research team led by the Universities of Göttingen and Madrid is the first to describe the internal anatomy of this intriguing animal.

The 'cell of origin' of the second most common lung cancer and the way that it becomes dominant in the lung have been discovered, in a new study in mice and humans from researchers at UCL, the Wellcome Sanger Institute and the University of Cambridge. The study, published in Science , found that a population of basal cells found in the trachea (windpipe) outcompetes other cell types and becomes dominant, eventually invading and occupying large areas of the lung.

Childhood trauma raises the risk of harmful alcohol use, smoking, and drug use by age 18, according to a new study from the Department of Psychology. A new study published in the Journal of Child Psychology and Psychiatry reveals that childhood trauma significantly increases the likelihood of engaging in risky behaviours, including harmful alcohol consumption, smoking and illicit drug use, by the age of 18.

Researchers use moss in new method capable of restoring peatlands damaged by oil and gas exploration   In what could represent a milestone in ecological restoration, researchers have implemented a method capable of restoring peatlands at tens of thousands of oil and gas exploration sites in western Canada.

An international research team made up of scientists from Freie Universität Berlin and the French National Center for Scientific Research (CNRS) in conjunction with Université de Lorraine in Metz, France, has achieved a significant breakthrough in the chemistry of fluorinated compounds. With the aid of quantum chemical simulations they were able to prove for the first time that heavy fluorine atoms can also "tunnel," or in other words, transform between two states.

New isotopic evidence deciphers breastfeeding and weaning trends in ancient Iberia What did babies eat 1500 years ago? International researchers led by the University of Bonn and the Nova University of Lisbon reconstructed the diet of children in Roman and medieval Portugal using state-of-the-art isotope methods to answer this question.

A research team at TU Graz has developed a system for structural monitoring that can be integrated directly into structural management and used sustainably for preventive maintenance planning. The safety and durability of transport and building infrastructure are in the interests of both operators and users.

Human fibroblasts observed by fluorescence microscopy. Mitochondria are marked in red, fibroblast core DNA is marked in blue © Nivea Dias Amoedo/Inserm A deterioration in skin quality, its ability to heal, and its normal aging, is often observed in people with chronic hyperglycemia. A team of researchers from Inserm, the University of Bordeaux and LVMH Recherche has investigated how hyperglycemia alters the human dermis, and in particular the cells involved in its healing, the fibroblasts.

An international study co-authored by McGill psychologist Caroline Palmer suggests our brains and bodies don't just understand music, they physically resonate with it. These discoveries, based on findings in neuroscience, music, and psychology, support Neural Resonance Theory (NRT). NRT maintains that rather than relying on learned expectations or prediction, musical experiences arise from the brain's natural oscillations that sync with rhythm, melody and harmony.

Why do some ancient animals become fossils, while others vanish without a trace - A new study from the University of Lausanne reveals that the size and chemical composition of an animal are among the determining factors in its chances of surviving millions of years as a fossil, or vanishing without a trace.that an animal's size and chemical composition are among the determining factors in its chances of surviving millions of years as a fossil, or vanishing without a trace.

Scientists have been divided for centuries by the question of what consciousness is. The two major theories have now been put to the test by a group of researchers, including neuroscientists Floris de Lange and Yamil Vidal from the Donders Institute at Radboud University, and have been found to be partly incorrect.
