Key points: A system which replicates the womb lining (endometrium) with high biological fidelity has been developed by researchers at the Babraham Institute and used to listen in to the communication that happens between the embryo and endometrium at the crucial stage of development when the embryo implants. Using donated endometrial tissue to seed the model, the approach provides the most advanced culture system for understanding how early-stage human embryos implant into the endometrium to establish ...

For many of us, the holiday season can mean delightful overeating, followed by recriminatory New Year’s resolutions. But eating enough and no more should be on the menu for all of us, according to a recent UBC study. It found that 44 per cent of us would need to change our diets for the world to warm no more than 2 C. Dr. Juan Diego Martinez, who led the research as a doctoral student at UBC’s Institute for Resources, Environment and Sustainability, discusses the study’s findings and the simple dietary changes we can all make. What did you find? Half of us globally and at least 90 per cent of Canadians need to ...

A study conducted during the 2024 French elections finds that information about immigrants’ efforts to overcome poverty and learn French reduces negative beliefs about immigration and modestly decreases opposition to immigration among voters. Amine Sijilmassi and colleagues conducted three studies in France examining whether emphasizing “deservingness” cues—such as immigrants’ motivation to work, efforts to learn French, job-seeking behavior, and children’s upward mobility—could reduce anti-immigration attitudes. In one study, 480 participants rated fictional immigrant profiles more favorably when the profiles exhibited deservingness traits. ...

The distribution of Japanese eels (Anguilla japonica) at the northern edge of the species’ range appears to be shaped by river water temperature, which is influenced by watershed geology and land use. Osamu Kishida and colleagues conducted electrofishing surveys in 105 rivers across southern Hokkaido, Japan, capturing 222 Japanese eels from 52 rivers. The authors used structural equation modeling that incorporated catch per unit effort, environmental variables, and estimates of glass eel recruitment—the number of juvenile eels that enter rivers from the sea, where ...

Electropulsing treatment (EPT) is a state-of-the-art technology for rapidly heating metallic materials. The highly energy-efficient and eco-sufficient process utilizes a pulsed current or ‘electropulse,’ achieving unique effects such as electroplasticity and electropulsing anisotropy. It facilitates fast microstructural evolution in alloys—compared to the conventional furnace heat treatment (FHT) technique—possibly via athermal contributions that go beyond the effects of Joule heating. Recent efforts by scientists to determine these athermal contributions have focused on ...

SEATTLE, WASH. — DECEMBER 23, 2025 — Scientists have engineered a protein able to record the incoming chemical signals of brain cells (as opposed to just their outgoing signals). These whisper-quiet incoming messages are the release of the neurotransmitter glutamate, which plays a critical role in how brain cells communicate with one another but until now has been extremely difficult to capture. Why it matters Understanding the brain’s code: Scientists can now study how neurons compute—how they take thousands of input signals and—based off those—produce an output signal that ...

Memories and learning processes are based on changes in the brain’s neuronal connections and, as a result, in signal transmission between neurons. For the first time, DZNE researchers have observed an associated phenomenon in living brains – specifically in mice. This mechanism concerns the cellular pulse generator for neuronal signals (the “axon initial segment”) and had previously only been documented in cell cultures and in brain samples. A team led by neuroscientist Jan Gründemann reports on this in the ...

NEW YORK, NY -- Dec. 23, 2025 -- Using marijuana just once or twice a month was associated with worse school performance and emotional distress for teens, according to a large national study of adolescents led by Ryan Sultán, an assistant professor of clinical psychiatry at Columbia University Vagelos College of Physicians and Surgeons. The more frequently teens used cannabis, the more likely they were to report emotional distress and other social and academic problems.  “While previous studies have focused on the effects of frequent ...

A major review of prior research has found no evidence that menopause hormone therapy either increases or decreases dementia risk in post-menopausal women, in a new study led by University College London (UCL) researchers. The findings, commissioned by the World Health Organisation (WHO) and published in The Lancet Healthy Longevity, add much-needed clarity to a hotly-debated topic, and reinforce current clinical guidance that menopause hormone therapy, also called hormone replacement therapy or HRT, should be guided by perceived benefits and risks and not for dementia prevention. The new systematic review and meta-analysis is the most comprehensive and rigorous ...

After traumatic brain injury (TBI), some patients may recover completely, while others retain severe disabilities. Accurately evaluating prognosis is challenging in patients on life-sustaining thery. Though resting-state functional MRI (rs-fMRI) can assess neurological activity shortly after brain injury, it is unknown whether communication across brain regions at this early juncture predicts long-term recovery. Investigators from Mass General Brigham and collaborators in the U.S. and Europe analyzed data from three prospective cohorts comprising 97 patients who underwent rs-fMRI after injury, finding that early communication between three pairs ...

The researchers have succeeded in tracing two classic hallmarks of cancer – the evasion of apoptosis (a form of programmed cell death) and the dysregulation of energy metabolism – back to a common molecular mechanism. The study focuses on the protein MCL1, which is strongly overexpressed in many tumor types and has previously been considered primarily an anti-apoptotic factor of the Bcl-2 protein family. The Dresden researchers now show that MCL1 directly influences the central metabolic regulator mTOR and thus controls the bioenergetics of cancer ...

About 300 years ago, Swedish naturalist Carl Linnaeus set out on a bold quest: to identify and name every living organism on Earth. Now celebrated as the father of modern taxonomy, he developed the binomial naming system and described more than 10,000 species of plants and animals. Since his time, scientists have continued to describe new species in the quest to uncover Earth's biodiversity. According to a new University of Arizona-led study published in Science Advances, scientists are discovering species quicker than ever before, with more than 16,000 new species discovered each year. ...
