MIT researchers identified three cognitive skills we use to infer what someone really means

2025-12-10
CAMBRIDGE, MA - In everyday conversation, it’s critical to understand not just the words that are spoken, but the context in which they are said. If it’s pouring rain and someone remarks on the “lovely weather,” you won’t understand their meaning unless you realize that they’re being sarcastic. Making inferences about what someone really means when it doesn’t match the literal meaning of their words is a skill known as pragmatic language ability. This includes not only interpreting sarcasm but also understanding metaphors and white lies, among many other conversational subtleties. “Pragmatics is trying to reason ...

The Iberian Peninsula is rotating clockwise according to new geodynamic data

2025-12-10
Plate tectonics can be visualized like large moving parts on the earth’s crust. The constant movement of the plates causes major stresses, and, as a result, deformations or earthquakes occur on the plate boundaries. “Every year the Eurasian and African plates are moving 4-6 mm closer to each other. The boundary between the plates around the Atlantic Ocean and Algeria is very clear, whereas in the south of the Iberian Peninsula the boundary is much more blurred and complex,” explained Asier ...

Stanford Medicine-led study identifies immune switch critical to autoimmunity, cancer

2025-12-10
A single signaling pathway controls whether immune cells attack or befriend cells they encounter while patrolling our bodies, researchers at Stanford Medicine have found. Manipulating this pathway could allow researchers to toggle the immune response to treat many types of diseases, including cancers, autoimmune disorders and those that require organ transplants. The research, which was conducted in mice, illuminates the mechanism of an important immune function that prevents inappropriate attacks on healthy tissue. Called peripheral immune tolerance, ...

Research Alert: How the Immune System Stalls Weight Loss

2025-12-10
Researchers at the University of California San Diego School of Medicine have uncovered a surprising new function for immune cells: preventing excess weight loss. In a recent study, the team demonstrates that when the body is exposed to physiological stressors, such as low temperature, neutrophils — a type of white blood cell — infiltrate fat tissue and release signals that slow fat breakdown. The researchers hypothesize that this mechanism helped our early human ancestors preserve vital energy stores when food ...

An old jeweler’s trick could unlock next-generation nuclear clocks

2025-12-10
Last year, a UCLA-led team accomplished something scientists have been trying to do for 50 years. They made radioactive thorium nuclei absorb and emit photons like electrons in an atom do. This achievement was the realization of a dream they first proposed in 2008 and is expected to usher in a new era of high-precision timekeeping, with a dramatic impact on navigation. It could also lead to new scientific discoveries that rewrite some of the fundamental constants of nature.    But there’s a catch. The isotope of thorium they need, thorium-229, can only ...

Older age, chronic kidney disease and cerebrovascular disease linked with increased risk for paralysis and death after West Nile virus infection

2025-12-10
Older people with a history of chronic kidney disease or conditions affecting blood flow to the brain such as stroke face about double the risk for developing neuroinvasive disease that can lead to paralysis and death following infection with West Nile virus, new UCLA research finds. The study, to be published December 10 in the peer-reviewed journal JAMA Network Open, also suggests that other factors such as male sex, hematologic malignancy, immune suppressants, hypertension, alcohol-related disorders and multiple sclerosis, contribute to the higher risk for developing neuroinvasive disease, which occurs when the ...

New immune role discovered for specialized gut cells linked to celiac disease

2025-12-10
New immune role discovered for specialized gut cells linked to celiac disease The human small intestine absorbs nutrients while protecting us from potentially harmful microbes. One of the cell types that plays a key role in this protection is the microfold cell, or M cell. These cells detect bacteria and other foreign particles and pass them on to immune cells. Until now, most knowledge about M cells came from studies in mice. In a new study published in Nature, researchers from the Clevers Group show that human M cells have additional immune functions. They do not only transport antigens, ...

A new ‘hypertropical’ climate is emerging in the Amazon

2025-12-10
The Amazon rainforest is slowly transitioning to a new, hotter climate with more frequent and intense droughts — conditions that haven’t been seen on Earth for tens of millions of years. The conclusions come from a new study led by the University of California, Berkeley, involving a large team of national and international scientists. The researchers predict that, if society continues to emit high levels of greenhouse gases, “hot drought” conditions could become more prevalent across the Amazon ...

Integrated piezoelectric vibration and in situ force sensing for low-trauma tissue penetration

2025-12-10
Minimally invasive tissue penetration techniques are increasingly demanded in biomedical applications such as neural probe implantation, ophthalmic surgery, and single-cell puncture. These procedures require highly precise penetration of biological membranes with minimal tissue damage, often relying on real-time force feedback to control insertion forces. Traditional methods typically use sharp micro-tools or robotic systems, which can lead to rapid insertion speeds, increasing tissue damage and inflammation risks. Additionally, the heterogeneous nature of biological tissues complicates the ability to adjust to varying mechanical properties. ...

Three-hit model describes the causes of autism

2025-12-10
A new University of California San Diego School of Medicine study offers a unified biological model to explain how genetic predispositions and environmental exposures converge to cause autism spectrum disorder (ASD). The study, published in Mitochondrion on Dec. 9, 2025, describes a “three-hit” metabolic signaling model that reframes autism as a treatable disorder of cellular communication and energy metabolism. The model also suggests that as many as half of all autism cases might be prevented or reduced with ...

Beech trees use seasonal soil moisture to optimize water uptake

2025-12-10
European beech trees, a key species in central Europe’s forests, are showing remarkable adaptability underground. A new study published in Forest Ecosystems reveals that these trees adjust the structure and growth of their fine roots according to seasonal soil moisture fluctuations, rather than the long-term wetness or dryness of their sites. The research team, led by scientists from Dresden University of Technology (TUD), Germany, monitored beech trees across three near-natural forest sites in Saxony, Germany, representing wet, intermediate, and dry soil conditions. Over a 30-month period, the team collected high-resolution data on fine root biomass, growth, ...

How thinning benefits growth for all trees

2025-12-10
A new study on intensively managed loblolly pine plantations in the southern United States reveals how trees compete for light and nutrients, and how thinning reshapes that competition. The findings, published in Forest Ecosystems, provide new insight into how forest management affects both tree growth patterns and overall productivity. Researchers from Zhejiang University and Stephen F. Austin State University tracked 48 plots of loblolly pine across Texas and Louisiana for seven years after mid-rotation thinning. They used two indicators to assess forest structure: the Gini index (GI), which measures differences in tree size, and growth ...

Researchers upgrades 3-PG forest model for improved accuracy

2025-12-10
The study, published in Forest Ecosystems, presents a refined update to the 3-PG (Physiological Processes Predicting Growth) model. Its major innovation is adding a carbon storage pool specifically for stem growth, making it possible for the model to account for the “carry-over effect” in which trees use carbohydrates stored from previous years to form new wood, particularly early in the growing season when photosynthesis is low. Including such physiological processes improved simulations in ...
