62% of Marine Protected Areas (MPAs) designated to protect rare migratory fish species are outside of their core habitats, according to a new modelling study. The findings are published in the British Ecological Society’s Journal of Applied Ecology. A team of researchers in France from the “Pole MIAME” that gathers diadromous fish experts from multiple research institutions (OFB, INRAE, Institut Agro and UPPA) have developed a new modelling approach that accurately predicts core and unsuitable habitats of rare and data-poor ...

The advancement of urbanization and globalization has impacted every corner of the Earth， human activities have transformed over one-third of the planet’s ecosystems, including agricultural lands and urban areas. Thus, there is an urgent need to define and achieve the equilibrium of novel ecosystems. This study employed pragmatic designed experiments as its core method, integrating methodologies from empiricism, positivism, and romanticism to propose a semi-empirical ecological design framework that emphasizes learning by doing and research through practice. ...

A new study by Chinese scientists, released on May 29 in Shanghai, has called for the use of consumption-based accounting (“CBA”) emissions in calculating global carbon emissions in order to help make allocating responsibility for reducing emissions just and fair. The study, “Research Report on Consumption-based Carbon Emissions (2024)” (“the Report”), was jointly completed by scientists from several institutes under the Chinese Academy of Sciences (CAS) as well as from Tsinghua University. The ...

The depletion of energy resources poses a significant threat to the development of human society. Specifically, a considerable amount of low-grade heat (LGH), typically below 100 °C, is currently being wasted. However, if harnessed effectively, it has the potential to significantly improve overall energy utilization efficiency and subsequently reduce carbon dioxide emissions. A research group of Junyong Hu from Taiyuan University of Technology has concentrated on developing a new type of reverse electrodialysis ...

The Colorado River is a lifeline for many cities and farms in the Southwest United States. It flows for about 1,448 miles before reaching the Gulf of California in Mexico and supplies water to numerous cities and farms along the way.   However, over the past 60 years, the amount of water in the Colorado River has been shrinking. In fact, in some years, the river’s water has been used up completely before it reaches the gulf. Landon Marston, assistant professor in civil and environmental engineering, teamed up with researchers from multiple universities and ...

According to a recent study published in Chemical Engineering Journal, a collaborative research team led by Professor WANG Hui from High Magnetic Field Laboratory, Hefei Institutes of Science of Chinese Academy of Sciences developed magnetite nanozyme (MNZs) with dual enzymatic activities through structural engineering, and proved its structure-dependent behavior in the process of tumor treatment. MNZs, as a substitute for natural enzymes, has been widely studied in the field of tumor catalytic therapy. However, the catalytic efficiency of traditional MNZs in tumor microenvironment (TME) is often limited, which is mainly due to the low production rate of hydroxyl radical ...

People have various relationships in society including those with family, friends, and coworkers. While these relationships play a significant role in our lives, it's crucial to maintain a healthy distance as being too close can lead to intense emotions or conflicts. Interestingly, a recent study in the field of chemistry demonstrates that maintaining such distance can enhance battery performance in electric vehicles.   In this research, Professor Soojin Park, Dr. Sungjin Cho and Youngjin Song, a PhD student, from the Department of Chemistry at Pohang University of Science and Technology (POSTECH) in collaboration with the team of Professor Sung Gap Im ...

Corals play an essential role in ocean ecosystems, and like many organisms, they are under threat from climate change and other human activities. To better protect coral, it’s first necessary to understand them, in particular their reproductive life cycle, which only happens once a year. For the first time, researchers have produced a model for coral spawning, based on various environmental factors. They achieved this by tapping an often overlooked source of aquatic knowledge, an aquarium. Given their branching shapes or waving tendrils, you would be ...

Research led by the University of Plymouth has shown that a new deep learning AI model can identify what happens and when during embryonic development, from video. Published today (Wednesday 29 May) in the Journal of Experimental Biology, the study highlights how the model, known as Dev-ResNet, can identify the occurrence of key functional developmental events in pond snails, including heart function, crawling, hatching and even death. A key innovation in this study is the use of a 3D model that uses changes occurring between frames of the video, and enables the AI to learn from these features, as opposed to the more traditional use of still images. The ...

Primates, including humans, have larger brains than most other mammals, but why? Scientists searching for the answer have long followed a trail pointing to diet—specifically fruit—as the reason for why primates evolved larger brains. A team from the Max Planck Institute of Animal Behavior and the Smithsonian Institute of Tropical Research tested this idea for the first time—finding that the fruit-diet theory might be out of juice. The researchers used drone imaging, GPS tracking, and fine-scale behavioral analyses to test how four species of fruit-eating mammals solved the same natural foraging puzzle in a Panamanian rainforest. They ...

A new paper published in The Quarterly Review of Biology examines the question of what Darwinism is and how its nonscientific uses relate to the scientific theory of evolution. Charles Darwin published On the Origin of Species in 1859 as a work in biology. However, in the past century and a half, Darwin’s ideas have impacted a broad range of domains and stimulated scientists and scholars to advance "evolutionary approaches" in domains as diverse as economics, engineering, psychology, and history. The ideas have been used (and abused) to undermine religiously inspired ideas about the origin of humans and their status concerning other species, ...

AUSTIN, Texas — Wifi-enabled washing machines. Voice-controlled microwaves. App-enabled TVs, vacuum cleaners, and even window blinds you can control from the comfort of your couch. Many of the technological features now included in everyday products are useful and accessible. But research has shown that having too many can overwhelm potential buyers, making them less likely to make a purchase. In new research, Wayne Hoyer, marketing professor and James L. Bayless/William S. Farrish Fund Chair for Free Enterprise at Texas McCombs, digs into the phenomenon of “feature creep” and its impact on consumer sentiment. ...

A new study by researchers from Arizona State University and their colleagues highlights a dietary strategy for significant health improvement and weight management. Participants following an intermittent fasting and protein-pacing regimen, which involves evenly spaced protein intake throughout the day, saw better gut health, weight loss and metabolic responses. These benefits were notably greater than those seen with simple calorie restriction. The findings, reported today in the journal Nature ...

AMES, Iowa – A widely found gene in plants has been newly identified as a key transporter of a hormone that influences the size of corn. The discovery offers plant breeders a new tool to develop desirable dwarf varieties that could enhance the crop’s resilience and profitability.  A team of scientists led by Iowa State University spent years working to pinpoint the functions of the gene ZmPILS6. Now, they have been able to characterize it as an important driver of plant size and architecture, a carrier for an auxin hormone that helps govern growth in roots below ground and shoots, or stalks, above ground. Their findings were published in the Proceedings ...

Many primary care clinicians directly receive messages from patients via electronic health records’ portal inboxes. The COVID-19 pandemic saw a rapid uptick in this trend. Data suggests that this additional work is linked to clinician burnout. Penn Family Care, a primary care group at Penn Medicine, instead routed incoming messages to certified medical assistants who had been taught how to distribute each message to the most appropriate physician. There was a 40% decrease in the number of messages going directly to primary care physicians, and both practice and clinician efficiency showed improvement after adopting this team-based care model. Utilizing Medical Assistants ...

Background and Goal: Relational continuity, the ongoing relationship between a patient and a family physician, is linked to better patient care, fewer unnecessary procedures, hospitalizations, emergency department visits, and lower costs, along with higher patient satisfaction. With the rise of part-time practices, patients often see multiple family physicians within the same clinic. This study aimed to explore how continuity in a primary care clinic—separate from individual physician continuity—affects patient ...

Background: Currently, people of Latiné/e/x/o/a, Hispanic, and/or Spanish (LHS) origin make up 19.1% of the population of the U.S. There is great variation in the personal experiences and family backgrounds of LHS individuals, including differences in country of origin, time in the U.S., colonization histories and immigration experiences. Key Argument: This essay considers the importance of recognizing the heterogeneity of lived experiences among LHS populations in the U.S. in a health care context. Why ...

Background and Goal: Family physicians perform a wide range of procedures outside the hospital and tend to be office based. Examples may include surgical procedures such as excisions, suturing, and joint injections. Since the training can vary substantially, the Council of Academic Family Medicine (CAFM)  issued a statement on which procedures they recommend physicians be able to perform competently upon completion of a family medicine residency. The aim of this study was to determine the extent to which family physicians perform CAFM-recommended procedures for Medicare Part B, the outpatient portion ...

Background and Goal: Breast cancer is the second most common cancer among women in the U.S. Early detection of the disease through screening can greatly improve the chances of successful treatment and is an essential preventive service in primary care. The COVID-19 pandemic interrupted breast cancer screening as many screening programs were temporarily suspended due to personal concerns about exposure to the virus and the burden on the health care system. The goal of this study was to use real-world electronic health records (EHR) across the U.S. to examine the changes in breast cancer screening utilization since the COVID-19 pandemic and how the follow-up screening rates were impacted ...

Background & Goal: Prior to the COVID-19 pandemic, 20% of adult primary care patients identified as lonely, representing a higher prevalence than many diseases commonly seen in primary care such as diabetes. Social isolation and loneliness are increasing over time, which is not only associated with increased health care utilization in primary care patients, but also with increased risk of chronic health conditions. Social isolation is reported to be equivalent to smoking 15 cigarettes per day in terms of premature death. The U.S. Surgeon General recently released an advisory entitled, “Our Epidemic of Loneliness and Isolation,” presenting a framework for action ...

Background: Prediabetes, a diagnosis intended to identify high-risk persons and prevent progression to diabetes, has been a topic of ongoing debate, and experts continue to disagree about its screening criteria, interpretation, and implications. Author Stance: An epidemiologist and health services researcher argues that prediabetes is overdiagnosed. A prediabetes diagnosis for patients like herself who are at low risk of developing type 2 diabetes can cause more harm than good. They may experience undue distress, undergo unnecessary consultations and tests, and pay additional health care costs. It may be implied—incorrectly—that ...

A research team designed a standardized process for helping low-income families navigate applications for federal nutrition support programs. Within a brief tablet-based nutrition screener completed at pediatric primary care visits, families were asked if they would like help applying for Women, Infants, and Children (WIC) and Supplemental Nutrition Assistance Program (SNAP) benefits. If they did, clinic staff followed up by telephone with application assistance. One limitation of this innovation is that some families were not able to be reached by telephone. Connecting ...

Background: A long-term relationship between a patient and their doctor, known as continuity of care, has seen a decline in recent decades in both the UK and the U.S. This decline has negatively impacted patient and physician health outcomes and  well-being. Editorial Stance: Building on Terrence McDonald and colleagues' research, which distinguishes between the continuity contributions of a practice and an individual clinician, increased physician continuity has been linked to reduced emergency department ...

Background and Goal: Nearly 500,000 children in the U.S. live with serious or life-threatening illnesses. Family caregivers, especially parents, face the challenges of managing complex medical needs, navigating the health system, and advocating for their children. This often leads to psychological distress, depression, and anxiety for caregivers. Understanding the experiences of parents of children with serious illnesses, especially those who are racially and ethnically diverse, remains limited. This study examined the experiences of Somali, Hmong, and Latin American parents in pediatric serious illness care, aiming to identify improvements and reduce disparities in pediatric ...
