Led by Director CHANG Sukbok, scientists from the Center for Catalytic Hydrocarbon Functionalizations within the Institute for Basic Science (IBS) have made a breakthrough in understanding the structure and reactivity of a key intermediate in catalytic reactions. This intermediate, known as a transition metal-nitrenoid, plays a crucial role in converting hydrocarbons into amides, which are important in pharmaceuticals and materials science. In chemical reactions, intermediates are substances that are formed and consumed during the transformation of reactants into products. Hence, understanding these intermediates ...

Microbial communities are widely used biotechnology suppliers for processes like manufacturing biofuels and new foods, or helping crops grow better. To engineer successful communities, scientists need to predict whether microorganisms can live and work together. One popular predictive rule states that if a pair of microbes will coexist, they will also coexist in a bigger community of microbes. A study published in Science now found that this simple rule will not always work. Just like plants and animals, microorganisms live in complex ecological communities consisting of multiple species that ...

LOGAN, UTAH, USA -- New analysis of samples collected from underneath Greenland’s ice sheet reveal the Arctic island was much greener as recently as 416,000 years ago. The findings overturn previous views that Greenland’s continental glacier, which covers about 80 percent of the 836,3000-square-mile land mass, has persisted for the last two and a half million years. “We’re discovering the ice sheet is much more sensitive to climate change than we previously thought,” says Utah State University geoscientist ...

HOUSTON – (July 20, 2023) – Visible light is a mere fraction of the electromagnetic spectrum, and the manipulation of light waves at frequencies beyond human vision has enabled such technologies as cell phones and CT scans. Rice University researchers have a plan for leveraging a previously unused portion of the spectrum. “There is a notable gap in mid- and far-infrared light, roughly the frequencies of 5-15 terahertz and wavelengths ranging from 20-60 micrometers, for which ...

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 ...

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 ...
