These findings highlight the urgent need for targeted public health interventions and enhanced surveillance, especially given ...

Paleontologists have identified a new species of dinosaur, Khankhuuluu, which is being described as the closest-known ancestor to the giant Tyrannosaurs. The finding by an international team of researchers – led by Jared Voris and Dr. Darla Zelenitsky in the Faculty of Science at the University of Calgary – is published in the journal Nature. Voris, first author and a PhD candidate in the Department of Earth, Energy, and Environment, says the new species of Tyrannosaur would have lived 86 million years ago and was a medium-sized, fleet-footed predator that evolved after the extinction of other large predatory dinosaurs. Khankhuuluu was ...

(Sacramento, Calif.) — Researchers at the University of California, Davis, have developed an investigational brain-computer interface that holds promise for restoring the voices of people who have lost the ability to speak due to neurological conditions. In a new study published in the scientific journal Nature, the researchers demonstrate how this new technology can instantaneously translate brain activity into voice as a person tries to speak — effectively creating a digital vocal tract. The system allowed the study participant, who has amyotrophic lateral sclerosis (ALS), to “speak” through a computer ...

PHILADELPHIA— Tailored feedback to surgeons dramatically cuts excessive opioid prescriptions for common surgeries, aligning them with evidence-based guidelines without affecting patient pain control. This approach offers a promising strategy to combat the opioid crisis by aligning prescribing practices with evidence-based guidelines, addressing the critical issue of overprescribing, where excessive opioid prescriptions can lead to harmful side effects and can lead to dependence in some patients or diversion of unused pills. The findings, by researchers in the Perelman School of Medicine at the University of Pennsylvania, were published ...

Key takeaways Accreditation doesn’t just recognize quality, it helps create it: In this large-scale analysis of American College of Surgeons quality accreditation programs, the authors found that the accreditation process often helps hospitals improve the care they provide. Just over half of hospitals obtain accreditation on their first attempt: 61% of hospitals that sought accreditation passed after the first site visit, and 80% of those that failed the initial attempt went on to pass on their second attempt. CHICAGO (June 11, 2025) — ...

A new pilot project led by McGill University researchers is showing early success in helping cancer survivors return to work, addressing an aspect of recovery they say is often overlooked. iCanWork is an online support program being developed by Christine Maheu, Associate Professor at McGill’s Ingram School of Nursing, in collaboration with BC Cancer. “Work isn’t considered a key health indicator in cancer care, even though it’s a major concern from the moment someone is diagnosed and is associated with better quality of life in survivors” said Maheu. Lingering side effects of cancer treatment like fatigue, “chemo brain” ...

PLYMOUTH MEETING, PA [June 11, 2025] — New research in the June 2025 issue of JNCCN—Journal of the National Comprehensive Cancer Network found that older people with cancer had better daily functioning, improved mood, stronger illness understanding, and a higher quality of life if they participated in a telehealth-based care program called Geriatric Assessment-Guided Intervention-Supportive Care (GAIN-S). GAIN-S’ supportive care services included personalized fitness training, nutritional support, psychiatric care, and psychosocial assistance, all delivered remotely. The randomized ...

Ischemic stroke exacts a heavy toll in death and disability worldwide. After ischemic stroke, the accumulation of pathobiomolecules in the brain extracellular space (ECS) will exacerbate neurological damage and cognitive impairment. “PBM has been demonstrated to improve cognitive function in Alzheimer’s disease mouse models by accelerating molecular transportation in the brain ECS. This suggests that PBM may have a potential role in the accumulation of pathobiomolecules in the brain ECS following ischemic stroke.” said ...

In the past 20 years, substantial progress has been made in the detection and stimulation technology of deep brain neural information; especially, the deep brain electrode array device has emerged in neuroscience research and clinical application. Primates possess a more developed central nervous system and a higher level of intelligence than rodents. Detecting and modulating deep brain activity in primates enhances our understanding of neural mechanisms, facilitates the study of major brain diseases, enables brain–computer interactions, and supports advancements in artificial intelligence. Traditional imaging methods such as magnetic resonance imaging, positron ...

Seagrasses are critical to coastal ecosystems – offering habitat, stabilizing the seafloor and buffering wave energy – but globally they’re increasingly under threat. Beginning in 2011, a series of intense algal blooms – fueled by pollution and nutrient overload – wiped out vast stretches of vital seagrass beds in Florida’s Indian River Lagoon (IRL). In the wake of this collapse, the fast-growing green seaweed Caulerpa prolifera has spread across areas once dominated by native seagrass species like Halodule wrightii, filling in the ...

Recent advances in robotic ultrasound systems have shown promise for improving diagnostic imaging consistency. However, maintaining stable contact force across dynamic physiological changes (e.g., breathing, tremors) without continuous sensor recalibration remains a critical hurdle. "By integrating a hybrid active-passive force control mechanism, our method decouples force regulation from real-time feedback dependencies while ensuring adaptability across patients," stated corresponding author Qingsong Xu, a professor at the University of Macau. The tripartite system combines (a) a passive constant-force mechanism (positive/negative stiffness ...

Drinking a smoothie is a popular way to consume fruits and vegetables, many of which are rich in micronutrients called polyphenols. If this beverage is purchased at a store, it’s likely been pasteurized with heat or pressure to prevent harmful bacteria growth and extend shelf-life. Now, a preliminary study in ACS’ Journal of Agricultural and Food Chemistry reports that processing smoothies with high heat could also make polyphenols easier for the gut microbiome to absorb. Fruits and vegetables are key to a healthful human diet, ...

Breathalyzers are a frequently used tool to measure the amount of ethanol in someone’s breath, which relates to their blood alcohol content. However, alcoholic beverages contaminated by methanol (sometimes called wood alcohol) are hard to identify and toxic if ingested. Researchers reporting in ACS Sensors have developed a prototype sensor that quickly and easily detects small amounts of methanol in breath — a step toward developing a “methanol breathalyzer” to efficiently diagnose poisonings. Methanol and ethanol, despite being structurally similar, have vastly different effects on the body when ingested. Ethanol gives ...

To treat bacterial infections, medical professionals prescribe antibiotics. But not all active medicine gets used up by the body. Some of it ends up in wastewater, where antimicrobial-resistant bacteria can develop. Now, to make a more efficient antibiotic treatment, researchers reporting in ACS Central Science modified penicillin, so that it’s activated only by green light. In early tests, the approach precisely controlled bacterial growth and improved survival outcomes for infected insects. “Controlling drug activity with light will allow precise and safe treatment of localized infections,” says Wiktor Szymanski, a corresponding author of the study. “Moreover, ...

The ghostly woman’s voice pipes through the speakers, covered in radio static but her message intact from beyond — “The birch canoe slid on the smooth planks.” A secret message from the other side? A spectral insight? No, something much spookier: Voice recordings captured, secretly, from the radio frequencies emitted by ubiquitous, cheap microphones in laptops and smart speakers. These unintentional signals pass, ghost-like, through walls, only to be captured by simple radio components and translated back to static-filled — but easily intelligible ...

The molecules that form the foundation of life on Earth are as diverse as they are complex. Among these, carbohydrates play a vital role as energy sources and in structural functions, such as forming cell walls. One class of carbohydrates, β-1,2-glucans, consists of glucose chains and is found in bacteria. These molecules are involved in various important biological processes, such as bacterial infection and environmental adaptation. Despite their biological significance, β-1,2-glucans are rare, compared to cellulose and laminarin, and structurally complex, making them particularly difficult to ...

Exercise has been recognized as an extremely effective tool to improve human health— it can have a preventative and even therapeutic effect on non-communicable diseases such as diabetes and cardiovascular diseases. By promoting physical activity not only among athletes, but also among the general population, several non-communicable diseases can be prevented, eventually reducing the financial burden upon the healthcare system. However, the exact changes that occur at a molecular level due to different types of exercise have not been explored thoroughly. One reason ...

No more hunger after cooking? A newly identified network of nerve cells is responsible, a research group at the Max Planck Institute for Metabolism Research has discovered in mice. They discovered a direct connection from the nose to a group of nerve cells in the brain that are activated by the smell of food and, when activated, trigger a feeling of fullness. This was not the case in obese mice. This discovery suggests that treating obesity might require different advice about smelling food before a meal based on a person's weight.  The researchers used brain scans to investigate which regions of the mice's brains respond to ...

Today, 2.2 billion people in the world lack access to safe drinking water. In the United States, more than 46 million people experience water insecurity, living with either no running water or water that is unsafe to drink. The increasing need for drinking water is stretching traditional resources such as rivers, lakes, and reservoirs.  To improve access to safe and affordable drinking water, MIT engineers are tapping into an unconventional source: the air. The Earth’s atmosphere contains millions of billions of gallons of water in the form of vapor. If this vapor can be efficiently captured and condensed, it could supply clean drinking water in ...

CAMBRIDGE, MA -- The human brain is very good at solving complicated problems. One reason for that is that humans can break problems apart into manageable subtasks that are easy to solve one at a time. This allows us to complete a daily task like going out for coffee by breaking it into steps: getting out of our office building, navigating to the coffee shop, and once there, obtaining the coffee. This strategy helps us to handle obstacles easily. For example, if the elevator is broken, we can revise how we get ...

The forerunners of dinosaurs and crocodiles in the Triassic period were able to migrate across areas of the ancient world deemed completely inhospitable to life, new research suggests.   In a paper published in Nature Ecology and Evolution today (11th June), researchers from the University of Birmingham and University of Bristol have used a new method of geographical analysis to infer how these ancestral reptiles, known as archosauromorphs, dispersed following one of the most impactful climate events the Earth has ever seen, the end-Permian mass extinction.   The first archosauromorphs, some resembling modern reptiles and many ...

Imagine you’re walking to work when the unspeakable occurs: Your favorite coffee shop — where you stop every day — is closed. You groggily navigate to a newly opened coffee shop a couple blocks away, which, you’re pleased to discover, actually makes quite a good morning brew. Soon, you find yourself looking forward to stopping at the new location instead of the old one. That switch probably alters more than just your morning routine. Each time you visit that new coffee shop, the ...

A team of Korean scientists has developed an innovative green technology that transforms plastic waste into clean hydrogen fuel using only sunlight and water. Researchers at the Institute for Basic Science (IBS) Center for Nanoparticle Research, led by Professor KIM Dae-Hyeong and Professor HYEON Taeghwan of Seoul National University, announced the successful development of a photocatalytic system that produces hydrogen from PET bottles. The key innovation lies in wrapping the photocatalyst in a hydrogel polymer, which helps it float on water and stay active even under harsh environmental ...

Brain cell discovery may explain excessive hunger Researchers identify “meal memory” neurons in laboratory rats that could explain why forgetting lunch leads to overeating. Scientists have discovered a specific group of brain cells that create memories of meals, encoding not just what food was eaten but when it was eaten. The findings, published today in Nature Communications, could explain why people with memory problems often overeat and why forgetting about a recent meal can trigger excessive hunger and lead to disordered eating. During eating, neurons in the ventral hippocampus region of the brain become active and form what the team of researchers call ...

A new study from Karolinska Institutet involving over a million women links difficult childhood experiences to the risk of being diagnosed with endometriosis later in life. The study shows a link between childhood exposure to violence and a twofold increase in the risk of developing this gynaecological disease. Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside the uterus. These cells attach to the abdominal lining, uterus, ovaries or other organs and form endometriosis lesions. The lesions react to ...
