UNIVERSITY PARK, Pa. —  At a time when Pennsylvania is actively working to achieve water-quality improvements to meet the state’s obligations for cleaning up the Chesapeake Bay, a multidisciplinary Penn State research team is studying whether agricultural pollution-prevention devices called riparian buffers are working properly.  Riparian buffers — areas adjacent to streams or wetlands that contain a combination of trees, shrubs and grasses — are managed differently from the surrounding landscape to provide conservation benefits. In agricultural areas, buffers intercept sediment, nutrients, pesticides and chemicals ...

Most women with ovarian cancer are diagnosed with the most advanced form of the disease. Less than a third of those diagnosed with the disease survive five years later. As the third most common type of gynecological cancer, it led to more than 200,000 reported deaths globally in 2020 alone, according to a recent study. In a study published this month in the Journal of Experimental & Clinical Cancer Research, University of Notre Dame researchers in collaboration with NeoGenomics Laboratories ...

Frontiers journals have adopted the Contributor Roles Taxonomy (CRediT) to improve the way authors' contributions to research are communicated and acknowledged. The new system replaces the conventional free-text authorship descriptions with a standardized and transparent system that ensures consistency and accuracy in recognizing individual contributions.  CRediT categorizes individual author contributions into well-defined roles and provides a clear, concise framework to describe the diverse contributions made by researchers ...

A research team supervised by a health policy researcher at the University of Chicago has found that increasingly common private equity investments in healthcare are generally associated with higher costs to patients and payers. That’s according to a new study published July 19 in The BMJ. The study is thought to be the first systematic review of global private equity ownership trends in medical settings. “Over the last few decades, private equity activity in healthcare has exploded, with financial institutions buying up hospitals, nursing homes and fertility ...

The transition to chaos is ubiquitous in nonlinear systems. Continuous-wave-driven photonic-chip-based Kerr microresonators exhibit spatiotemporal chaos, also known as chaotic modulation instability. For more than fifteen years such modulation instability states have been considered impractical for applications compared to their coherent-light-state counterparts, such as soliton states. The latter have been the centerpiece for numerous high-profile application demonstrations, from long-range optical communication to photonic computing. Now, researchers from the group of Tobias Kippenberg at EPFL have found a new way to harness the unique features of chaotic frequency combs to implement ...

For years, unrecycled plastic bottles have been dumped in landfills. Now, thanks to new research from UBC Okanagan, those bottles may have a second life in that landfill—stabilizing its earth walls. Used plastic bottles and textiles pose an increasing problem for landfills worldwide. Researchers say nearly a hundred million metric tons of polyethylene terephthalate (PET), also known as microplastics, are produced globally each year—with a fraction of that number being recycled—making it one of the largest sources of plastic waste. “One ...

Bat activity falls as farms make the transition to organic agriculture, new research shows. Organic farming is better for biodiversity than conventional farming, which relies heavily on substances such as pesticides, herbicides and fertilisers. However, little is known about how wildlife is affected by the transition period when a farm goes organic. The new study, led by the universities of Bristol, Göttingen and Exeter, assessed the effects of organic farming by monitoring insect-eating bats at citrus ...

Post-menopause female killer whales protect their sons – but not their daughters – from fights with other whales, new research shows. Scientists studied “tooth rake marks” – the scarring left when one whale scrapes their teeth across the skin of another – and found males had fewer marks if their mother was present and had stopped breeding. Only six species – humans and five species of toothed whales – are known to experience menopause, and scientists have long been puzzled about why this occurs. The new study – by the universities ...

Seagrasses evolved from freshwater plants and use sunlight and carbon dioxide (CO2) for photosynthesis and are able to thrive in depths down to 50 metres. In contrast to algae, they possess roots and rhizomes that grow in sandy to muddy sediments. The grass-like, leaf-shoots produce flowers and complete their life cycle entirely underwater. Seeds are negatively buoyant but seed-bearing shoots can raft, thus greatly enhancing dispersal distances at oceanic scale. As a foundational species, eelgrass provides critical shallow-water habitats for diverse biotas and also provides numerous ecosystem services including carbon uptake. Seagrasses have recently been recognised as one of the important ...

WASHINGTON, DC – The Patient-Centered Outcomes Research Institute (PCORI) today announced the approval of $9 million for the first seven studies through its groundbreaking Science of Engagement initiative.

Like us, cells communicate. Well, in their own special way. Using waves as their common language, cells tell one another where and when to move. They talk, they share information, and they work together – much like the interdisciplinary team of researchers from the Institute of Science and Technology Austria (ISTA) and the National University of Singapore (NUS). They conducted research on how cells communicate – and how that matters to future projects, e.g. application to wound healing. What comes to your mind when you think of biology? Animals, plants, theoretical computer models? The last one, you might not associate with it right away, although ...

Key Takeaways: Volunteering later in life may protect the brain against cognitive decline and dementia. New study of older adults found better memory and executive function among those who volunteered. Watch the video. (Sacramento) Volunteering in late life is associated with better cognitive function — specifically, better executive function and episodic memory. Those are the findings of a new study from UC Davis Health presented today (July 20) at the Alzheimer’s Association International Conference 2023 in Amsterdam. “We ...

From life-saving drugs and synthetic polymers to diverse advanced materials, the products containing organic compounds seem endless, thanks in part to regioselectivity, a feature in chemical reactions where a substituent is selectively added to a specific position of an organic compound. This favors the formation of desired products with specific functionalities. One notable regioselective reaction used for the precise design of organic compounds is the Friedel−Crafts reaction, which enables the addition of substituents to specific positions on aromatic compounds ...

Omega-3 fatty acids appear promising for maintaining lung health    NIH-funded study supports new role for nutrient found in fish, dietary supplements   Omega-3 fatty acids, which are abundant in fish and fish oil supplements, appear promising for maintaining lung health, according to new evidence from a large, multi-faceted study in healthy adults supported by the National Institutes of Health. The study provides the strongest evidence to date of this association and underscores the importance of including omega-3 fatty acids in the diet, especially given that many Americans do not meet current guidelines. Funded largely by the National Heart, ...

The goal of both the CREX and PREX-II experiments was to run an experiment and its mirror opposite simultaneously to determine ...

ATLANTA, July 20, 2023 – A new study from researchers at the American Cancer Society (ACS) found that Black cancer survivors in the United States experience a higher risk of dying from cardiovascular disease (CVD) compared with White cancer survivors. The research showed Black cancer survivors carry from 30% up to a three-fold higher mortality risk from CVD, depending on the type of cancer that was diagnosed. Differences in neighborhood socioeconomic status and health insurance between Black and White cancer survivors explained the disparities in cardiovascular death rates between populations, according to the study authors. ...

Researchers from The University of Tokyo unravel the connection between high body temperature and increased viral resistance. Clinical evidence suggests that elderly individuals are at a higher risk of contracting viral infections. Quite notably, the older people also have lower mean body temperatures. However, the effects of increased body temperature on fighting viral infections remain largely unexplored. A team of Japanese researchers has now been able to bridge the gap by linking higher body temperature with an increased infection-fighting capability of the gut microorganisms or "microbiota." Their study was published in Volume 14 ...

People with more positive perceptions of their nation’s institutions are more likely to show favoritism toward fellow citizens, according to new research in Social Psychological and Personality Science. This research suggests that support for national institutions could pose a challenge for establishing trust across borders. Researchers also found that people who identify strongly with their own nation are likely to favor their fellow citizens, which aligns with previous studies. The possible role of trust in national institutions, however, was an unexpected development for researchers. “We observed greater favoritism in trust toward fellow citizens ...

The proper response to various abiotic stresses is essential for plants’ survival to overcome their sessile nature, especially for perennial trees with very long-life cycles. However, in conifers, the molecular mechanisms that coordinate multiple abiotic stress responses remain elusive. This article has been published on Horticulture Research with title: An ethylene-induced NAC transcription factor acts as a multiple abiotic stress responsor in conifer. Here, the transcriptome response to various abiotic stresses like salt, cold, drought, heat shock and osmotic were systematically detected in Pinus tabuliformis (P. ...

The fastest way to heat food and drink might also rank as the fastest route to ingesting massive quantities of minuscule plastic particles, says new research from the University of Nebraska–Lincoln. Experiments have shown that microwaving plastic baby food containers available on the shelves of U.S. stores can release huge numbers of plastic particles — in some cases, more than 2 billion nanoplastics and 4 million microplastics for every square centimeter of container. Though the health effects of consuming micro- and nanoplastics remain unclear, the Nebraska team further found that three-quarters of cultured embryonic ...

Cancer is one of the most devastating diseases in the world. In 2023, more than 1.9 million new cancer cases and 609,820 deaths are projected to occur in the United States alone. As efforts are underway to improve diagnostic tools, microRNAs are at the forefront biomedical research. MicroRNAs, or miRNAs, are a class of small non-coding ribonucleic acids (RNAs), which are essential for all biological functions. The main role of miRNA in the human body is gene regulation. As such, they regulate a variety of biological and pathological processes, including the formation and development of cancer. In fact, many cancers are closely associated with ...
