Lost signal: How solar activity silenced earth's radiation
2025-11-19
Researchers from HSE University and the Space Research Institute of the Russian Academy of Sciences analysed seven years of data from the ERG (Arase) satellite and, for the first time, provided a detailed description of a new type of radio emission from near-Earth space—the hectometric continuum, first discovered in 2017. The researchers found that this radiation appears a few hours after sunset and disappears one to three hours after sunrise. It was most frequently observed during the summer months and less often in spring and autumn. However, by mid-2022, when the Sun entered a phase of increased activity, the radiation had completely ...
Genetically engineered fungi are protein packed, sustainable, and taste similar to meat
2025-11-19
In a new study publishing November 19 in the Cell Press journal Trends in Biotechnology, researchers used a gene-editing technology called CRISPR to increase a fungus’s production efficiency and cut its production-related environmental impact by as much as 61%—all without adding any foreign DNA. The genetically tweaked fungus tastes like meat and is easier to digest than its naturally occurring counterpart.
“There is a popular demand for better and more sustainable protein for food,” says corresponding author Xiao Liu of Jiangnan University in Wuxi, China. “We successfully made a fungus not only more nutritious but also more environmentally ...

Trends in prevalence of adverse childhood experiences among children
2025-11-19
About The Study: This cross-sectional study reveals an encouraging positive shift in the prevalence of adverse childhood experiences (ACEs) among U.S. children during the study period of 2016 to 2023. The upward trends in the proportion of individuals reporting 0 ACEs suggest a growing societal recognition of the importance of healthy and nurturing environments for children. Conversely, the decrease in the prevalence of 4 or more ACEs highlights a reduction in severe ACEs, particularly among other racial and ethnic groups and those from low-income families.

Surface-only superconductor is the strangest of its kind
2025-11-19
Something strange goes on inside the material platinum-bismuth-two (PtBi₂). A new study by researchers at IFW Dresden and the Cluster of Excellence ct.qmat demonstrates that while PtBi₂ may look like a typical shiny grey crystal, electrons moving through it do some things never seen before.
In 2024, the research team demonstrated that the top and bottom surfaces of the material superconduct, meaning electrons pair up and move without resistance. Now, they reveal that this pairing works differently from any superconductor ...
Stereotactic radiosurgery for craniopharyngioma management
2025-11-19
Craniopharyngiomas account for 2–5% of all primary brain tumors and 5–10% of pediatric brain tumors. Despite their benign histology, their location near the hypothalamus, pituitary gland, and optic pathways complicates management. Gross total resection, while effective, carries high risks of visual, endocrine, and hypothalamic dysfunction. Adjuvant radiotherapy after subtotal resection offers comparable control with fewer complications, but conventional fractionated radiotherapy is associated with long-term risks such as cognitive decline, secondary malignancies, and ...
Study questions water safety beliefs
2025-11-19
PULLMAN, Wash. – A Washington State University-led study in Guatemala found the sources of drinking water people believe to be safe and clean often contain potentially dangerous bacteria.
Focusing on the Western Highlands region of Guatemala, researchers examined how community perceptions of water safety compared with actual water quality. While residents overwhelmingly believed bottled water sold in large refillable jugs to be the safest option for drinking, researchers found that of 11 water sources tested it was the most frequently contaminated with coliform bacteria – an indicator of fecal contamination. ...
Bacteria ‘pills’ could detect gut diseases — without the endoscope
2025-11-19
Move over, colonoscopies — researchers report in ACS Sensors that they’ve developed a sensor made of tiny microspheres packed with blood-sensing bacteria that detect markers of gastrointestinal disease. Taken orally, the miniature “pills” also contain magnetic particles that make them easy to collect from stool. Once excreted from mouse models with colitis, the bacterial sensor detected gastrointestinal bleeding within minutes. The researchers say the bacteria in the sensor could be adapted to detect other gut diseases.
“This ...

2025-11-19
Jennifer Munson, a cancer researcher at Virginia Tech's Fralin Biomedical Research Institute at VTC, has been awarded two new National Institutes of Health grants to advance greater understanding and improved treatment of a deadly brain cancer.
While the grants from the National Cancer Institute fund different projects, both involve identifying how the movement of fluid surrounding tumor cells contributes to the spread of glioblastoma, a deadly brain tumor, into neighboring brain areas, allowing the cancer to return after surgery or radiation.
Munson and her team are identifying how liquid called interstitial fluid moves between ...
New global satellite dataset for humanitarian routing and tracking infrastructure change
2025-11-19
While many global road maps exist, few include detailed surface information or keep pace with rapid infrastructure change. The new HeiGIT dataset closes this gap by combining 3–4 meter resolution PlanetScope imagery (2020–2024) with deep-learning models to analyze 9.2 million kilometers of major transport routes connecting cities and rural regions. The result is a high-accuracy global classification (89.2%), outperforming widely used open datasets by over 20 percentage points.
A central component of the dataset is the Humanitarian Passability Score — an index that combines surface type and ...

Why top firms paradoxically fire good workers
2025-11-19
Why do the world’s most prestigious firms—such as McKinsey, Goldman Sachs and other elite consulting giants, investment banks, and law practices—hire the brightest talents, train them intensively, and then, after a few years, send many of them packing? A recent study in the American Economic Review concludes that so-called adverse selection is not a flaw but rather a sign that the system is working precisely as intended.
Two financial economists, from the University of Rochester and the University of Wisconsin–Madison respectively, created a model that explains how reputation, information, ...

Phase 2 clinical trial results show potential to shorten TB treatment time
2025-11-19
COPENHAGEN (November 19, 2025)—New clinical trial results presented by TB Alliance at the Union World Conference on Lung Health show that the novel antibiotic candidate sorfequiline (TBAJ-876), a next-generation diarylquinoline, has the potential to improve tuberculosis (TB) treatment when combined with pretomanid and linezolid in a treatment regimen known as “SPaL.”
The NC-009 trial (a pan-Phase 2 clinical trial) showed that, overall, sorfequiline had greater activity than bedaquiline. The 100 mg SPaL regimen had greater activity against TB than the standard of care HRZE (isoniazid, rifampin, pyrazinamide, and ethambutol), indicating the potential ...
UC San Diego researchers expand virus-based treatment options for antibiotic-resistant infections
2025-11-19
Antibiotic resistance is one of the most pressing challenges to global public health as harmful microbes evolve to evade these medications. Now, researchers at University of California San Diego and their colleagues have developed a new method to combat antibiotic-resistant bacteria using bacteriophages, or phages, for short — viruses that infect and kill bacteria — as an alternative to traditional antibiotics.
The researchers targeted Klebsiella pneumoniae, a species of bacteria notorious for its ability to resist multiple antibiotics. The dangerous pathogen can cause severe infections in hospital settings, including pneumonia and ...
New magnetic component discovered in the faraday effect after nearly two centuries
2025-11-19
Researchers at the Hebrew University of Jerusalem discovered that the magnetic component of light plays a direct role in the Faraday Effect, overturning a 180-year-old assumption that only its electric field mattered. Their findings show that light can magnetically influence matter, not just illuminate it. The discovery opens new possibilities in optics, spintronics, and quantum technologies.
Researchers from the Hebrew University of Jerusalem have discovered that the magnetic component of light, not ...
AI tool spots blood cell abnormalities missed by doctors
2025-11-19
An AI tool that can analyse abnormalities in the shape and form of blood cells, and with greater accuracy and reliability than human experts, could change the way conditions such as leukaemia are diagnosed.
Researchers have created a system called CytoDiffusion that uses generative AI – the same type of technology behind image generators such as DALL-E – to study the shape and structure of blood cells.
Unlike many AI models, which are trained to simply recognise patterns, the researchers – ...
People in isolated cities in Africa suffer more violence against civilians
2025-11-19
[Vienna, 19.11.2025]—Cities are often seen as hotspots of violence, with the assumption that larger cities are inherently more violent than smaller ones. This “universal law” of urban scaling has long shaped scientific thinking. But new research led by Complexity Science Hub (CSH) researcher Rafael Prieto-Curiel challenges this assumption. Published in Nature Communications, the study shows that it is not simply city size, but a city’s level of isolation, that plays a crucial role in determining violence in Africa.
“Our analysis shows that the 10% most populous cities in Africa (216 cities in total) contain 66% of the urban population but only ...
New antibodies developed that can inhibit inflammation in autoimmune diseases
2025-11-19
An international research group directed by UMC Utrecht have developed and characterized two first-in-class antibodies that specifically block the high-affinity IgG receptor FcγRI. Their findings open new perspectives for therapeutic modulation of FcγRI-driven inflammation in autoimmune diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and immune thrombocytopenia (ITP).
FcγRI, also known as CD64, is a high-affinity receptor on myeloid cells that binds to the Fc region of immunoglobulin G (IgG) antibodies. It plays a key role in the immune defense by triggering cellular functions such as phagocytosis ...

How do winter-active spiders survive the cold?
2025-11-19
Spiders of the Clubiona genus, which are among the most important natural enemies of pests found in orchards, are active during the winter. New research in The FEBS Journal reveals the characteristics of antifreeze proteins that these spiders produce that bind to ice crystals and prevent their growth at sub-zero temperatures, which helps the animals avoid freezing.
Using mass spectrometry to investigate these proteins at a molecular level, investigators found that although the Clubiona antifreeze proteins resemble those found in beetles and moths, ...
