Continents peel from below, triggering oceanic volcanoes

2025-11-11
Earth scientists have discovered how continents are slowly peeled from beneath, fuelling volcanic activity in an unexpected place: the oceans. The research, led by the University of Southampton, shows how slivers of continents are slowly stripped from below and swept into the oceanic mantle – the hot, mostly solid layer beneath the ocean floor that slowly flows. Here, the continental material fuels volcanic activity for tens of millions of years. The discovery solves a long-standing geological mystery: why many ocean islands far from plate tectonic ...

Where does continental material on islands come from?

2025-11-11
Many oceanic islands far from active plate tectonic boundaries contain materials that clearly originate from continents, even though they are located in the middle of an oceanic plate. Where do the continental remnants come from? Are they sediments that are recycled when oceanic plates subduct into the mantle? Or do they originate from the depths of the Earth's mantle and are carried upward by hot currents, known as mantle plumes? Both explanations are being discussed, but they fall short. This is because some volcanic regions show little evidence of crustal recycling, while others are too cool to be driven by mantle plumes. Researchers at the University of Southampton and the GFZ Helmholtz ...

New drug target identified in fight against resistant infections

2025-11-11
The discovery of a new mechanism of resistance to common antibiotics could pave the way for improved treatments for harmful bacterial infections, a study suggests. Targeting this defence mechanism could aid efforts to combat antimicrobial resistance (AMR), one of the world’s most urgent health challenges, researchers say. Findings from the study reveal how a repair system inside some bacteria plays a pivotal role in helping them survive commonly-used antibiotics. Many of these drugs work by targeting the production of proteins essential for bacterial growth and survival. Now, researchers from the University of Edinburgh have identified ...

Male pregnancy: a deep dive with seahorses

2025-11-11
Reversed sex roles: In seahorses, it is the males who carry offspring to term. The females lay their eggs into a special brood pouch on the bellies of the males where they are fertilized by the male’s sperm. In the brood pouches, embryos are provided with nutrients and oxygen from the males' bodies until the males give live birth to small seahorses (viviparity). But how does this work? A German-Chinese research team led by evolutionary biologist Axel Meyer from the University of Konstanz and working in collaboration with Liu Yali and Lin Qiang from the South China Sea ...

Nanopores act like electrical gates

2025-11-11
Pore-forming proteins are found throughout nature. In humans, they play key roles in immune defense, while in bacteria they often act as toxins that punch holes in cell membranes. These biological pores allow ions and molecules to pass through membranes. Their unique ability to control molecular transport has also made them powerful nanopore tools in biotechnology, for example in DNA sequencing and molecular sensing. Despite their importance and impact on biotechnology, biological nanopores can also ...

AI adoption in the US adds ~900,000 tons of CO₂ annually, equal to 0.02% of national emissions

2025-11-11
A new study published in Environmental Research Letters finds that continued growth in artificial intelligence (AI) use across the United States could add approximately 900,000 tonnes of CO₂ annually. This is not a small amount but equates to a relatively minor increase when viewed in the context of nationwide emissions. While AI adoption is expected to boost productivity and economic output, researchers note that its environmental footprint can be seen as relatively modest compared to other industrial activities. The study examined potential AI integration across various sectors, estimating ...

Adenosine is the metabolic common pathway of rapid antidepressant action: The coffee paradox

2025-11-11
NEW YORK, New York, USA, 11 November 2025 -- Perhaps the most intriguing implication of recent breakthrough research lies in an unexpected connection: the most rigorous mechanistic dissection of rapid antidepressant action identifies adenosine as the critical mediator, yet adenosine receptors are the primary target of caffeine, the world's most widely consumed psychoactive substance. A commentary published today in Brain Medicine by Drs. Julio Licinio and Ma-Li Wong explores this striking convergence. Is this merely coincidence, or ...

Vegan diet can halve your carbon footprint, study shows

2025-11-11
Only around 1.1% of the world's population is vegan, but this percentage is growing. For example, in Germany the number of vegans approximately doubled between 2016 and 2020 to 2% of the population, while a 2.4-fold increase between 2023 and 2025 to 4.7% of the population has been reported in the UK. Many people cite health benefits as their reason to go vegan: moving from a typical Western diet to a vegan one can lower the risk of premature mortality from noncommunicable diseases by an estimated 18% to 21%. Another excellent reason is to reduce your ecological footprint. Now, a study in Frontiers in Nutrition has calculated precisely how ...

Anti-amyloid therapy does not change short-term waste clearance in Alzheimer’s

2025-11-11
A group from Osaka Metropolitan University in Japan, led by graduate student Tatsushi Oura and Dr. Hiroyuki Tatekawa, found that treatment using the drug lecanemab to remove amyloid plaques in the brain does not change the waste clearance function in the brains of Alzheimer’s disease (AD) patients in the short term. This suggests that even after treatment, the AD patients’ nerves are already damaged, and the waste clearance function does not recover in the short term. Their findings show the complexity of the disease and the need to address multiple disease-causing pathways simultaneously in the future. Their findings add to the complicated process of unraveling ...

Personalized interactions increase cooperation, trust and fairness

2025-11-11
A new setup for social games suggests that when people are given the freedom to tailor their actions to different people in their networks, they become significantly more cooperative, trusting and fair. The international study with Kobe University participation thus argues that many standard experimental setups of cooperation underestimate people’s prosocial potential. Games that are models of social interactions are used in sciences spanning from sociology and anthropology to psychology and economics, giving us very concrete data on how likely it is that people behave in a certain way in certain social contexts. For example, when modeling how people cooperate in social networks, ...

2025-11-11
Risk prediction tools might help identify patients at the highest risk of overdose and death after a “before medically advised” (BMA) hospital discharge according to new research in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.250492. Patients who leave hospital against the advice of a physician are about twice as likely to die and about 10 times more likely to experience an illicit drug overdose in the first 30 days after leaving hospital. Such BMA discharges are initiated ...

Dreaming of fewer running injuries? Start with better sleep

2025-11-11
If you are among the 620 million people who lace up their running shoes on a regular basis, chances are that you’re an early riser. Hopefully, you will have got at least eight hours of good sleep the night before, otherwise your risk of injury skyrockets. That’s the finding from a new study led by Professor Jan de Jonge, a work and sports psychologist at Eindhoven University of Technology in the Netherlands, and an Adjunct Professor at the University of South Australia. In a survey of 425 recreational runners, Prof de Jonge and his team found that those reporting shorter sleep duration, lower sleep ...

USC study links ultra-processed food intake to prediabetes in young adults

2025-11-11
More than half of calories consumed in the United States come from ultra-processed foods (UPFs), items like fast food and packaged snacks that are often high in sodium, sugar and unhealthy fats. In adults, research has clearly linked these foods to type 2 diabetes and other conditions, but few studies have explored their effects among youth. Now, researchers from the Keck School of Medicine of USC have completed one of the first studies to examine the link between UPF consumption and how the body processes glucose, which is ...

How life first got moving: nature’s motor from billions of years ago

2025-11-11
Research led by the University of Auckland has cast light on the evolutionary origins of one of nature’s first motors, which developed 3.5 billion to 4 billion years ago to propel bacteria. Scientists have created the most comprehensive picture yet of the evolution of bacterial stators, proteins with roles similar to pistons in a car engine, says Dr Caroline Puente-Lelievre, of the School of Biological Sciences. Stator proteins sit in the bacterial cell wall, transforming charged particles (ions) into torque, creating propulsion for bacteria to swim. Stators likely evolved from ion transporter ...

Feeling fit, but not fine: ECU study finds gap between athletes’ health perceptions and body satisfaction 

2025-11-11
New research from Edith Cowan University (ECU) has revealed a striking disconnect between how recreational athletes perceive their health and fitness, and how they feel about their bodies.   The research found that while 69 per cent of recreational athletes that participated in a survey considered themselves healthy and 62 per cent believed they were fit, only 26 per cent reported being satisfied with their body weight and shape.   The findings confirm a concerning trend that athletes, particularly those engaged in regular or structured physical activity, are statistically more likely to experience disordered eating and exercise behaviours ...

The flexible brain: How circuit excitability and plasticity shift across the day

2025-11-11
Our brains do not react in a fixed, mechanical way like electronic circuits. Even if we see the same scene every day on our commute to work, what we feel - and whether it leaves a lasting impression - depends on our internal state at that moment. For example, your commute may be a blur if you're too tired to pay attention to your surroundings. The 24-hour cycle that humans naturally follow is one of the factors that shapes the brain's internal environment. These internal physiological cycles arise from ...
