HOUSTON – (Sept. 24, 2025) – Rice University researchers used a focused electron beam to pattern device functions with submicron precision directly into an ultrathin crystal. The approach produced traces narrower than the width of a DNA helix that glow with bright blue light and conduct electricity, showing it could be used to manufacture compact on-chip wiring and built-in light sources. “The electron beam essentially works as a nanoscale pencil,” said Hae Yeon Lee, an ...

In the delivery room, circumstances can turn dire on a dime if the patient starts losing excessive amounts of blood. One minute she seems fine, and the next, vital signs plummet, the patient crashes, and the care team may need to scramble for a blood transfusion or perform surgery. All too often, that alert may arrive too late. Postpartum hemorrhage is the leading cause of maternal death worldwide. Patients themselves may not notice, and there are few ways to easily measure the blood pouring out (or pooling in the uterus) during delivery. Even the most eagle-eyed doctor or nurse cannot ...

RIVERSIDE, Calif. -- Crimean-Congo hemorrhagic fever virus, or CCHFV, is a biosafety level 4 pathogen and a Category A bioterrorism agent, causing severe viral hemorrhagic fever with mortality rates reaching up to 40%. Already endemic in Africa, the Balkans, the Middle East, and much of Asia, the virus has recently expanded to Western Europe, carried by ticks on migratory birds. There is currently no approved vaccine or specific antiviral therapy for CCHFV. Scott Pegan, a professor of biomedical sciences at the University of California, Riverside School of Medicine, has now been awarded a grant from the National Institutes of Health ...

CAR T cells are patient-derived, genetically engineered immune cells. They are “living drugs” and constitute a milestone in modern medicine. Equipping T cells, a key cell type of the immune system, with a “chimeric antigen receptor” (CAR) enables them to specifically recognize and attack cancer cells. CAR T cell therapy has demonstrated its potential by curing patients with otherwise untreatable blood cancers. But it still fails for most patients, often due to T cell intrinsic dysfunction. ...

Quantum computers will need large numbers of qubits to tackle challenging problems in physics, chemistry, and beyond. Unlike classical bits, qubits can exist in two states at once—a phenomenon called superposition. This quirk of quantum physics gives quantum computers the potential to perform certain complex calculations better than their classical counterparts, but it also means the qubits are fragile. To compensate, researchers are building quantum computers with extra, redundant qubits to correct any errors. That is why robust quantum computers will require hundreds of thousands of qubits.   Now, ...

Hoboken, N.J., September 24, 2025 — A new study published in the Journal of Management Studies uncovers how top executives rise to celebrity status on social media — and why it matters for business and beyond.  Drawing on more than a decade of data from 320 CEOs of S&P 1500 companies with personal accounts on X (formerly Twitter), researchers analyzed over 250,000 CEO posts and 1.6 million user mentions of those CEOs. They found that CEOs who post more often, use a positive tone, and discuss a variety of topics are significantly more likely to receive high levels of both ...

The rapid growth of AI is driving great interest in building large, power-hungry data centers across the state. The University of Texas at Austin has launched a new research consortium to help inform industry partners on options for more sustainable growth of this new industry. The consortium – called Collaborative Optimization & Management of Power Allocation, Surface & Subsurface strategies (COMPASS) – was announced last week at a data center workshop for industry leaders and policy makers led by the UT Bureau of Economic Geology, which is part of the Jackson School of Geosciences. “Our goal is to bring all the players to the table,” said ...

A recent study links exposure to radiation from medical imaging to a small-but-significant risk of blood cancers among children and adolescents.  But do not panic. The study concludes the benefits of medical imaging outweigh the minimal risks.  Funded by the National Cancer Institute, the study will help medical personnel make informed decisions about using imaging on children. The study concluded that while ionizing radiation is a carcinogen, the benefit-to-risk ratio favors CT imaging of children when imaging is justified and the technique minimizes adverse ...

He will present “Seafaring in Space: A Personal Voyage to Enceladus,” discussing the Saturn moon with a deep ocean beneath its frozen surface, offering some of the most compelling evidence of habitability in our solar system. AGU, the world’s largest Earth and space science association, ...

ROCHESTER, Minn. — More than 4 million people worldwide have end-stage kidney disease that requires hemodialysis, a treatment in which a machine filters waste from the blood. Hemodialysis is a precursor to kidney transplant. To prepare for it, patients typically undergo surgery to connect an artery and a vein in the arm, creating an arteriovenous fistula (AVF) that allows blood to flow through the vein for treatment. However, AVF fails about 60 percent of the time due to vein narrowing. This is a major barrier to effective treatment. Mayo Clinic researchers found that transplanting patients' own stem cells from fat cells into the ...

As a graduate student living in New Haven, Connecticut, Elizabeth Roberto said she couldn’t stop wondering why certain neighborhoods seemed connected while others were quietly walled off. “There were these places where the roads just stopped,” Roberto recalled. “Like they were meant to go somewhere — but didn’t.” It was the kind of everyday thing the average person might drive past without a second thought. But for Roberto, it sparked a question that would stay with her for years: What happens when barriers separate people — not ...

About The Study: In this binational study of older adults with diabetes, nearly 6 in 10 U.S. adults and 3 in 10 Japanese adults discontinued glucagon-like peptide-1 receptor agonists (GLP-1RAs) within 12 months of initiating injectable semaglutide. Patients with established cardiovascular disease and chronic kidney disease had higher discontinuation rates in both countries, which is troublesome given the substantial clinical benefit these high-risk individuals would be expected to derive from GLP-1RA therapy.

About The Study: In this repeated cross-sectional study of 149,000 children in a large central Ohio primary care network during the 20 months after outbreak onset, all measures of measles-mumps-rubella (MMR) coverage remained well below the 93% herd immunity threshold. These persistent, population-wide immunity gaps suggest the need for sustained, equity-focused public health strategies to maintain measles elimination. Corresponding Author: To contact the corresponding author, Rosemary A. Martoma, ...

About The Study: This cross-sectional study found that considerable variation in price markup exists across hospitals and that high-markup hospitals demonstrated both lower quality and value of care. These findings underscore that high-markup hospitals represent a key initial target for national policy efforts targeting pricing regulation, transparency, and quality improvement.  Corresponding Author: To contact the corresponding author, Peyman Benharash, MD, email pbenharash@mednet.ucla.edu.

Researchers at the University of Exeter have created a detailed temporal map of chemical changes to DNA through development and aging of the human brain, offering new insights into how conditions such as autism and schizophrenia may arise. The team studied epigenetic changes - chemical tags on our DNA that control how genes are switched on or off. These changes are crucial in regulating the expression of genes, guiding brain cells to develop and specialise correctly. One important mechanism, called DNA methylation, ...

Researchers from Mass General Brigham and the Broad Institute of MIT and Harvard have identified genetic modifications that can improve the efficacy of chimeric antigen receptor (CAR)-T cell treatment — an immunotherapy that uses modified patient T cells to target cancer. The study used CRISPR screening to pinpoint genes that influenced T cell function and survival in culture and in a preclinical model of multiple myeloma. Their results and technique, published in Nature, could lead to T cell-based immunotherapies for cancer. “We ...

Recent studies suggest that the steady rise in life expectancy observed over the past 200 years has now stagnated. Data indicate that a limit has been reached, and that medical and healthcare advances no longer affect longevity in developed countries as they did in previous decades. Today, ageing itself, rather than disease, is the real frontier of human longevity. But what exactly is ageing? And can it be addressed in the same way as a disease? A team led by Dr Manel Esteller, Head of the Cancer Epigenetics group at the Josep Carreras Leukaemia Research Institute, has just ...

Embargoed for release: Wednesday, September 24, 2025, 11:00 AM ET Key points: By their 18th birthday, 61% of U.S. children have relied on Medicaid or the Children’s Health Insurance Program (CHIP), and 42% have experienced gaps in coverage, according to estimates from a microsimulation model. Disruptions to insurance coverage were more common among children covered by Medicaid or CHIP at birth in states that did not expand their Medicaid adult programs. States that set the most restrictive income eligibility thresholds for children under Medicaid and CHIP saw the highest share of coverage disruptions. The ...

Hospitals with the widest difference between the cost of their services and what they charge patients and their insurance carriers are mostly for-profit, investor owned and located in large metropolitan areas. They also have significantly worse patient outcomes compared with lower-cost hospitals, new UCLA research finds. These “high-markup hospitals” (HMH), which comprised about 10% of the total the researchers examined, charged up to 17 times the true cost of care. By contrast, markups at other hospitals were an average of three times the cost of care. The findings will be published September ...

The research team conducted an in-depth study of the evolution and domestication of barley (Hordeum vulgare). They focused on so-called haplotypes - sections of DNA that are inherited together and act like genetic “building blocks.” To trace barley’s history, the scientists analysed the genetic material of 682 barley accessions from the IPK genebank and 23 archaeological barley finds, including ancient charred grains up to 6,000 years old. The team specifically studied 380 wild barley samples from regions across western and central Asia, and compared them with 302 samples ...

During the course of evolution, the mammalian cranio-mandibular secondary joint—formed by the dentary condyle and the squamosal glenoid fossa, which replaced the reptilian articular–quadrate joint—represents an innovative structure in vertebrate evolution. By CT-scanning two classic fossils, Chinese researchers found previously unknown jaw joints and proposed a clear, four-step sequence showing how chewing and hearing functions were gradually split between jaw and ear. The research was led by Prof. MAO Fangyuan from the Institute of Vertebrate Paleontology and Paleoanthropology of ...

UNSW Sydney nano-tech startup Diraq has shown its quantum chips aren’t just lab-perfect prototypes – they also hold up in real-world production, maintaining the 99% accuracy needed to make quantum computers viable. Diraq, a pioneer of silicon-based quantum computing, achieved this feat by teaming up with European nanoelectronics institute Interuniversity Microelectronics Centre (imec). Together they demonstrated the chips worked just as reliably coming off a semiconductor chip fabrication line as they do in the experimental conditions of a research ...

Traditionally, chemical reactions have been described as one-line “equations” in which substrates, say A and B, convert purposefully but rigidly into a desired product, say C. Naturally, it has been recognized that byproducts may also form, but these have been generally considered undesirable and unproductive. The current research demonstrates that this view is very fragmentary and insufficient: in reality, chemical reactions – even those studied since the 19th century – are complex reactivity networks that, depending on the concentrations of ...
