Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, resulted in the detection of an exceptional gamma-ray flare from this object.
Quantum thermal machines are devices that leverage quantum mechanical effects to convert energy into useful work or cooling, similarly to traditional heat engines or refrigerators. Thermodynamics theory suggests that increasing the reliability with which all thermal machines
The study reveals that widely used heart-attack risk calculators fail to flag nearly half of those who will soon experience a cardiac event. Even the newer PREVENT model misclassifies many patients as low-risk. Since most people develop symptoms only within 48 hours of their
The material used to build the Temple of Venus in Naples has remarkably endured even as Earth's surface around it sank from volcanic activity, and researchers were curious to know how.
Spermine, a small but powerful molecule in the body, helps neutralize harmful protein accumulations linked to Alzheimer’s and Parkinson’s. It encourages these misfolded proteins to gather into manageable clumps that cells can more efficiently dispose of through autophagy.
Texas A&M researchers found a way to make stem cells produce double the normal number of mitochondria using nanoflower particles. These energized stem cells then transfer their surplus “power packs” to weakened cells, reviving their energy production and resilience. The method

A 20-year project in Bangladesh reveals that lowering arsenic levels in drinking water can slash death rates from major chronic diseases. Participants who switched to safer wells had the same risk levels as people who were never heavily exposed. The researchers tracked
RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study published in Nature Communications by Marcia group, has captured, for the first
Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists know that Pol II must advance down the gene in perfect sync with other
Climate change conditions turn plastics into more mobile, persistent, and hazardous pollutants. This is done by speeding up plastic breakdown into microplastics—microscopic fragments of plastic—spreading them considerable distances, and increasing exposure and impact within the
They say an elephant never forgets—and it turns out they can learn to adapt to drones. Once seen as a source of alarm, drones are now proving to be surprisingly elephant-friendly and a valuable research tool. Previously, the use of drones in elephant conservation has mostly

A bull shark killed a woman swimming off a remote beach in Australia's eastern state of New South Wales Thursday while a man was seriously injured and may have been saved by the "heroic" efforts of a passerby.
The world's top wildlife trade body rejected new protections for eels on Thursday in a secret ballot at talks in Uzbekistan.
European Union countries are progressing toward the United Nations Sustainable Development Goals (SDGs), but not at the same pace.
Scientists studying young adults with obesity discovered early indicators of brain stress that resemble patterns seen in cognitive impairment. The group showed higher inflammation, signs of liver strain and elevated neurofilament light chain, a marker of neuron injury. Low
A massive veteran study found a strong connection between untreated sleep apnea and a higher chance of Parkinson’s. CPAP users had much lower odds of developing the condition. Researchers believe that repeated dips in oxygen during sleep may strain neurons over time. The
The cherry harvest wrapped up months ago. But in northern Michigan, some growers are already anticipating the spring resurgence of a tiny raptor that could benefit next season's crop.
As climate change and the resulting extreme weather intensify, interest in weather modification is growing around the world. In Japan, under Goal 8 of the Moonshot Research and Development Program led by the Cabinet Office / JST (Japan Science and Technology Agency), a research
Around 80% of proteins involved in diseases like cancer and neurodegenerative illnesses do not have a stable structure. These proteins, known as intrinsically disordered proteins (IDPs) can quickly adapt to the conditions in our cells. A better understanding could aid in
Shallow seas serve as critical transition zones connecting land and the deep ocean, supplying essential resources for navigation, fisheries, energy exploration, and island reef development. Accurate bathymetric data form the foundation for marine engineering, channel safety,

Using its Near-InfraRed Camera (NIRCam), NASA's James Webb Space Telescope captured never-before-seen details of the Red Spider Nebula, a planetary nebula, in this image released on Oct. 26, 2025. NIRCam is Webb's primary near-infrared imager, providing high-resolution imaging
Daily steroid pills are often necessary for severe cases of asthma, but they raise the risk of several serious conditions. Now, scientists have shown that a monthly antibody injection can eliminate the need for the pills
