Accurate gas detection is a cornerstone of energy security, environmental monitoring, and medical diagnosis. However, developing a miniaturized device that achieves both high selectivity (distinguishing specific gases) and high sensitivity (detecting trace amounts) has long presented a significant challenge. Traditional spectroscopic methods often struggle to identify complex gas mixtures without relying on bulky equipment or broad spectral bandwidths. Research group at the University of Electronic Science and Technology of China (UESTC) has achieved a major breakthrough in this field. Published in the journal PhotoniX, their study introduces ...

Bar Harbor, Maine — As people age, muscles naturally lose mass and strength, a condition known as sarcopenia. The decline can make everyday activities harder and increases the risk of falls, disability and early death. At the moment, the best defense is regular exercise throughout our lives, as effective treatments to slow or prevent muscle atrophy are limited. Progress has been slowed in part because in most vertebrates, aging unfolds over many years, making it difficult for biomedical researchers to study quickly in the laboratory. Now, MDI Biological Laboratory Associate Professor Romain Madelaine, ...

A key molecular mechanism drives the growth of liver cell cancer while simultaneously suppressing the body's immune response to the tumor. This has now been published in the journal Nature by a team led by researchers from the German Cancer Research Center (DKFZ), the University Hospital of Tübingen, and the Sanford Burnham Prebys Medical Discovery Institute in La Jolla, California. However, the results also show that this very mechanism could help identify patients who respond particularly well to immunotherapy in the future, thus opening up new therapeutic approaches. Liver cell cancer is particularly difficult to treat ...

MADISON — Parts of the ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought. New research led by scientists at the University of Wisconsin–Madison has uncovered chemical signatures in zircons, the planet’s oldest minerals, that are consistent with subduction and extensive continental crust during the Hadean Eon, more than 4 billion years ago. The findings challenge models that have long considered Earth's earliest times as dominated by a rigid, unmoving ...

Researchers from the Centre for Addiction and Mental Health (CAMH) and the Institute of Neurophysiology at Uniklinik RWTH Aachen in Germany have deciphered the molecular signature of so-called sleeping nociceptors—a type of pain-sensing nerve cell that normally remains quiet and does not respond to touch or pressure, but can become overactive and drive chronic pain. The findings will be published on Wednedsay, February 4 in the renowned scientific journal Cell. Approximately ten percent of the population lives with neuropathic (nerve-related) pain, which is frequently associated with abnormal activity of sleeping nociceptors. ...

Cambridge, Mass. -- You can tell a lot about a material based on the type of light you shine at it: Optical light illuminates a material’s surface, while X-rays reveal its internal structures and infrared captures a material’s radiating heat.  Now, MIT physicists have used terahertz light to reveal inherent, quantum vibrations in a superconducting material, which have not been observable until now.  Terahertz light is a form of energy that lies between microwaves and infrared radiation on the electromagnetic spectrum. It oscillates over a trillion times ...

Parkinson’s disease, a progressive neurological disorder affecting more than 1 million people in the U.S. and more than 10 million globally, is characterized by debilitating symptoms such as tremors, movement difficulties, sleep disturbances and cognitive impairments. While current treatments, including long-term medication and invasive deep brain stimulation (DBS), can alleviate symptoms, they cannot halt progression or cure the disease. A new international study led by China’s Changping Laboratory, in collaboration with Washington University School of Medicine in St. Louis ...

Keeping up with the latest research is vital for scientists, but given that millions of scientific papers are published every year, that can prove difficult. Artificial intelligence systems show promise for quickly synthesizing seas of information, but they still tend to make things up, or “hallucinate.”  For instance, when a team led by researchers at the University of Washington and The Allen Institute for AI, or Ai2, studied a recent OpenAI model, GPT-4o, they found it fabricated 78-90% of its research citations. And general-purpose AI models like ChatGPT often can’t access papers that were ...

University of Toronto researchers have expanded our understanding of bacterial immunity with the discovery of a new protein that can both sense and counteract viral infections. In the new study, published today in Nature, researchers from U of T’s Temerty Faculty of Medicine describe how a single protein named Rip1 recognizes bacteriophages, the viruses that infect bacteria, and cause infected bacteria to die prematurely, thereby ending the chain of transmission. “There are a lot of parallels between our immune system and bacterial ...

Gene regulation is far more predictable than previously believed, scientists conclude after developing deep learning model PARM. This might bring an end to a scientific mystery: how genes know when to switch on or off. Today, scientists publish in Nature about their relentless back-and-forth between lab experiments and computation that enabled them to build this lightweight model. Scientists around the world can now start using this tool for reading these genetic instructions, creating leads for new cancer diagnostics, patient stratification, and future therapies. “The ...

UVA Comprehensive Cancer Center scientists have identified a molecule that blocks the gene responsible for glioblastoma, raising hopes that the molecule could become a much-needed new treatment for the deadliest brain cancer.  Researcher Hui Li, PhD, previously discovered the “oncogene” responsible for glioblastoma, a cancer for which there are no treatments that extend life for more than a few months. In his follow-up work, published in Science Translational Medicine, Li reports the identification of a small molecule that blocked the gene’s activity in both cell samples and lab mice. In mice, ...

Did you skip your last high school reunion? If so, you may want to reconsider when the next anniversary rolls around. The experience could lead to increased feelings of gratitude, according to a new study led by Jeffrey Green, Ph.D., a professor of psychology in Virginia Commonwealth University’s College of Humanities and Sciences. That’s because engaging in nostalgic experiences – or even just listening to nostalgic music, or drifting into a nostalgic reverie – can strengthen feelings of social connection, ...

Researchers studying the malaria parasite Plasmodium falciparum have discovered a previously unknown stage in its life cycle that appears to be crucial for reproduction. This is important because malaria depends on the parasite’s rapid ability to multiply inside the human body, so stopping its reproduction could help prevent severe disease and save lives. Using a new live-imaging method, the team found that before the parasite can divide, a key structure inside the cell must reshape into a “Crown” form and connect to the cell’s nucleus. This ...

Chemicals brought in to help protect our ozone layer have had the unintended consequences of spreading vast quantities of a potentially toxic ‘forever chemical’ around the globe, a new study shows. Atmospheric scientists, led by researchers at Lancaster University, have for the first time calculated that CFC replacement chemicals and anaesthetics are behind around a third of a million tonnes (335,500 tonnes) of a persistent forever chemical called trifluoroacetic acid (TFA) being deposited from the atmosphere across the Earth’s surface between the years 2000 and 2022. And the rate ...

PULLMAN, Wash. — The secret to youthful appearance and repairing scars may lie in a microscopic skin structure humans share with pigs and grizzly bears — but, surprisingly, not monkeys. While it had been thought these ridge and valley-like skin microstructures — called rete ridges — form during fetal growth, researchers at Washington State University’s College of Veterinary Medicine found they actually develop shortly after birth and identified a key molecular signal that drives their development. The findings, published in the journal Nature, could lead to new therapies designed to reverse or slow skin aging and improve wound and scar ...

Low back pain (LBP) is one of the most common health problems worldwide, affecting people of all ages and placing a heavy burden on healthcare systems. Many patients experience persistent discomfort that interferes with work, sleep, and daily activities. Yet in most cases, doctors cannot identify a clear structural cause, making long-term treatment difficult. A new study published in Volume 14 of the journal Bone Research on January 22, 2026, suggests that a hormone treatment may help relieve chronic back pain by limiting abnormal nerve growth inside damaged spinal ...

Plants are a rich and renewable source of compounds used in medicines, food ingredients, and cosmetics. Since growing an entire plant just to extract a few specific compounds is rather inefficient, scientists are turning to plant cell cultures as a more sustainable alternative. Cultured plant cells can act as ideal ‘biofactories’ that multiply quickly indoors and are unaffected by weather or seasons. Unfortunately, this strategy faces a long-standing problem: although plant cells contain thousands of genes capable of making diverse chemicals, only a small fraction of them are active under standard culture conditions. One possible ...
