Researchers at McGill University, in collaboration with Polytechnique Montréal, pioneered a new way to create hydrogels using ultrasound, eliminating the need for toxic chemical initiators. This breakthrough offers a faster, cleaner and more sustainable approach to hydrogel fabrication, and produces hydrogels that are stronger, more flexible and highly resistant to freezing and dehydration. The new method also promises to facilitate advances in tissue engineering, bioadhesives and 3D bioprinting.  Hydrogels are gels composed of polymers ...

Millions of kilometres of rivers around the world are carrying antibiotic pollution at levels high enough to promote drug resistance and harm aquatic life, a McGill University-led study warns. Published in PNAS Nexus, the study is the first to estimate the scale of global river contamination from human antibiotics use. Researchers calculated that about 8,500 tonnes of antibiotics – nearly one-third of what people consume annually – end up in river systems around the world each year even after in many cases ...

Most scientists look at DNA behavior in isolation, without considering how matter within a cell interacts with DNA Researchers observed DNA strand separation preceding replication and repair suppressed by molecules pushing strands together Findings challenge the standard in biochemical practice of heating DNA to separate strands EVANSTON, Ill. --- By creating a more true-to-life representation of DNA’s environment, researchers at Northwestern University have discovered that strand separation — the essential process a “resting” double helix undergoes before it can initiate replication or make repairs — may take more mechanical force ...

What happens when trailblazing engineers and industry professionals team up? The answer may transform the future of computing efficiency for modern data centers. Data centers house and use large computers to run massive amounts of data. Oftentimes, the processors can’t keep up with this workload because it’s taxing to predict and prepare instructions to carry out. This slows the flow of data. Thus, when you type a question into a search engine, the answer generates more slowly or doesn’t provide the information you need. To remedy this issue, researchers at Texas ...

New research led by Irish scientists has uncovered how lipid-rich fluid in the abdomen, known as ascites, plays a central role in weakening the body’s immune response in advanced ovarian cancer. The findings offer new insights into immune suppression in ovarian cancer and open promising avenues for future immunotherapy approaches. Over 70% of patients with ovarian cancer are diagnosed at an advanced stage, often presenting with large volumes of ascites. This ascites fluid not only supports the spread of cancer throughout the abdominal cavity but also ...

To the point Chimpanzees are capable of complex communication: The human capacity for language may not be as unique as previously thought. Chimpanzees have a complex communication system that allows them to combine calls to create new meanings, similar to human language. Combining calls creatively: Chimpanzees use four ways to change meaning when combining single calls into two-call combinations, including compositional and non-compositional combinations, and they use a large variety of call combinations in a wide range of contexts. Origins of language: The discovery of a complex communication system in chimpanzees has important ...

Mahadevan and Dr. Kimberly Bowal at Harvard. Their approach connects simple, active ...

UNIVERSITY PARK, Pa. — For the first time, scientists have discovered fossil evidence of an endangered, living tropical tree species. The unprecedented find was made in Brunei, a country on the large island of Borneo, and reveals a critical piece of the ancient history of Asia’s rainforests, highlighting the urgent need for conservation in the region, according to researchers at Penn State who led the discovery.   The research team published their findings in the American Journal of Botany.  The fossils, at least two million years old, represent the first direct ...

Fanconi anemia is an aggressive, life-threatening disorder. Most individuals living with this rare genetic condition, characterized by bone marrow failure and cancer predisposition, survive into adulthood only with bone marrow transplantation and regular cancer screening. But a new study demonstrates that mutations in one particular gene in the Fanconi anemia pathway result in an even more severe form of the disorder—and that many fetuses with this mutation do not survive to birth. The sobering findings, published in the Journal of Clinical Investigation, ...

“[…] we report that METTL3, an oncogene regulates the expression of SMAD4, a tumor-suppressor via miR-146a-5p, thus unveiling a novel regulatory axis of METTL3/miR-146a-5p/SMAD4 in OSCC, which can potentially have therapeutic implications.” BUFFALO, NY – May 9, 2025 – A new research paper was published in Oncotarget, Volume 16, on May 8, 2025, titled “METTL3 promotes oral squamous cell carcinoma by regulating miR-146a-5p/SMAD4 axis.” In this study, researchers Jayasree Peroth Jayaprakash, Pragati Karemore, and Piyush Khandelia from the Birla Institute of Technology and ...

 Toronto - The plumber has just left after fixing that leaky basement pipe. Ping – a phone alert asks you to rate their service. Hmm -- if it wasn’t an outright terrible job, do you give them three, four or five stars? New research from the University of Toronto’s Rotman School of Management shows that a multi-point system like that is prone to subtle, often unconscious, racial bias -- yet with significant financial consequences for non-white workers. Using data from a real-life online home maintenance matching service, researchers showed white workers ...

UNIVERSITY PARK, Pa. — Carbyne, a one-dimensional chain of carbon atoms, is incredibly strong for being so thin, making it an intriguing possibility for use in next-generation electronics, but its extreme instability causing it to bend and snap on itself made it nearly impossible to produce at all, let alone produce enough of it for advanced studies. Now, an international team of researchers, including from Penn State, may have a solution.   The research team has enclosed carbyne in single-walled carbon nanotubes — tiny, tube-shaped ...

A new study published in Social Psychological and Personality Science examines how expressions of moral outrage on social media are linked to online activism, specifically petition signing behavior. A research team led by Dr. Stefan Leach from Lancaster University analyzed over 1.2 million posts on X (formerly Twitter) containing links to nearly 25,000 petitions on Change.org. The findings reveal a surprising disconnect: while expressions of moral outrage significantly increase a post's virality (likes and reposts), they ...

The deconstruction of cellulose is essential for the conversion of biomass into fuels and chemicals. But cellulose, the most abundant renewable polymer on the planet, is extremely recalcitrant to biological depolymerization. Although composed entirely of glucose units, its crystalline microfibrillar structure and association with lignin and hemicelluloses in plant cell walls make it highly resistant to degradation. As a result, its degradation in nature is slow and requires complex enzymatic systems. The deconstruction ...

Background: Krebs von den Lungen-6 (KL-6), predominantly expressed by type II alveolar cells, is linked to the prognosis and severity of interstitial lung disease (ILD). This investigation sought to explore the relationship between KL-6 concentrations and the presence of ILD versus interstitial lung abnormalities (ILA). Methods: This single-center retrospective study included 147 patients who were suspected of ILD and underwent KL-6 testing between October 2022 and March 2023. Epidemiological and clinical details of the patients, including the outcomes of pulmonary function tests and computed tomography findings, were retrospectively extracted from electronic medical records. Results: The ...

New research from a team of cognitive scientists and evolutionary biologists finds that chimpanzees drum rhythmically, using regular spacing between drum hits. Their results, publishing in the Cell Press journal Current Biology on May 9, show that eastern and western chimpanzees—two distinct subspecies—drum with distinguishable rhythms. The researchers say these findings suggest that the building blocks of human musicality arose in a common ancestor of chimpanzees and humans. “Based on our previous work, we expected that western chimpanzees would use more hits and drum more ...

Wasp mothers have stunning brainpower when it comes to feeding their young, new research shows. Digger wasps make a short burrow for each egg, stocking it with food and returning a few days later to provide more. The study reveals that mother wasps can remember the locations of up to nine separate nests at once, rarely making mistakes despite the fact nests are dug in bare sand containing hundreds belonging to other females. Mothers feed their young in age order, adjusting the order if one dies, and they can even delay feeding offspring that had ...

More Americans use illicit opioids such as fentanyl than previously estimated, highlighting the need for better methods to understand the depths of the opioid crisis, according to a new study. A survey of American adults found that 11% reported illicit opioid use within the past 12 months and 7.5% reported use of illicitly produced fentanyl during the same period, rates that are more than 20 times higher than estimates from a large federal study that annually asks Americans about their use of illicit drugs. Researchers say the findings add to the evidence that government counts may significantly underestimate illicit drug use and suggest ...

About The Study: In this national survey of 1,515 adults conducted in June 2024, 166 respondents (11.0%) reported illicit opioid use and 114 (7.5%) reported illicitly manufactured fentanyl use within the past 12 months. These rates are much higher than previously reported estimates. The findings highlight the need for more timely and accurate data to inform policy and intervention strategies. Enhanced data collection efforts are essential for understanding and mitigating the opioid crisis.

About The Study: Vaccine effectiveness (VE) for the respiratory syncytial virus (RSV) protein subunit vaccine in this case-control study was similar to the VE in clinical trials. The VE for immunocompromised patients was mildly (overall) to moderately (for stem cell transplant recipients) diminished. Risk of immune thrombocytopenic purpura after vaccination was not elevated, but the risk of Guilain-Barré syndrome was statistically significantly elevated in patients who received the RSVPreF vaccine but not in those who received RSVPreF+AS01 vaccine, although the risk was small. These observations should inform clinicians’ choices ...

More than a decade ago, researchers launched the BabySeq Project, a pilot program to return newborn genomic sequencing results to parents and measure the effects on newborn care. Today, over 30 international initiatives are exploring the expansion of newborn screening using genomic sequencing (NBSeq), but a new study by researchers from Mass General Brigham highlights the substantial variability in gene selection among those programs. In a paper published in Genetics in Medicine, an official journal ...

When fruit flies are infected with the Wolbachia bacteria, their sex lives — and ability to reproduce — change dramatically. Arizona State University scientist Timothy Karr decided to find out why. What he discovered could help curb mosquito-borne diseases and manage crop pests. And that’s just the “tip of the iceberg,” he says. Promiscuous flies Wolbachia is a parasitic bacteria that lives inside insect cells. It infects at least two out of every five insect species. Since insects outnumber all other life on Earth, understanding how this bacteria affects them could have wide-ranging impacts. “Insects rule this planet. Malaria, ...

Tempted to skip the floss? Your heart might thank you if you don’t. A new study from Hiroshima University (HU) finds that the gum disease bacterium Porphyromonas gingivalis (P. gingivalis) can slip into the bloodstream and infiltrate the heart. There, it quietly drives scar tissue buildup—known as fibrosis—distorting the heart’s architecture, interfering with electrical signals, and raising the risk of atrial fibrillation (AFib). Clinicians have long noticed that people with periodontitis, a common form of gum disease, seem more prone to cardiovascular problems. One recent meta-analysis has linked it to a 30% higher risk of ...
