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 ...

Highlights Associate Professor Yuji Ogihara of Aoyama Gakuin University reviews empirical studies that examined temporal changes in the frequency of (un)common names. Accumulated evidence has demonstrated that uncommon names increased over time in many nations: Germany, the U.S., the U.K., France, Japan, China, and Indonesia. All the nations that were examined have shown an increase in uncommon names. Thus, the phenomenon is observed more generally, not locally in some limited nations. This increase in uncommon names reflects broader ...

Researchers have quantified the role of obesity in common long-term conditions, showing for the first time the effect of losing weight in preventing multiple diseases.   Conditions that often occur together may share an underlying cause, which can be key to prevention or treatment. The picture of which conditions co-occur is complex, so researchers paired them together, to allow them to identify shared causes more simply. The study found that obesity is the ...

Australian researchers have developed a powerful new way to target deadly, drug-resistant bacteria by designing antibodies that recognise a sugar found only on bacterial cells – an advance that could underpin a new generation of immunotherapies for multidrug resistant hospital-acquired infections. Published in Nature Chemical Biology, the research shows that a laboratory-made antibody can clear an otherwise lethal bacterial infection in mice by homing in on a distinctive bacterial sugar and flagging the pathogen ...

A major new World Health Organization publication sets out, for the first time, a practical, evidence-based package of care to address the mental health impacts of neglected tropical diseases (NTDs) and the stigma that can prevent people from seeking care and participating fully in society. The Essential care package to address mental health and stigma for persons with neglected tropical diseases responds to growing evidence that people living with NTDs experience higher rates of depression, anxiety, distress and suicidal behaviours than the general population, driven not only by the direct effects of illness but by stigma, discrimination ...
