CORVALLIS, Ore. – Oregon State University researchers estimate that gray whales feeding off the Oregon Coast consume up to 21 million microparticles per day, a finding informed in part by poop from the whales. Microparticle pollution includes microplastics and other human-sourced materials, including fibers from clothing. The finding, just published in the journal Frontiers in Marine Science, is important because these particles are increasing exponentially and predicted to continue doing so in the coming decades, according to researchers Leigh Torres and Susanne Brander. Microparticle pollution is a threat to the health of ...

Surgical and intensive care patients face a higher risk of death and longer hospital stays because they are susceptible to both hypotension and hemodynamic instability – or unstable blood flow. These potential complications require round-the-clock monitoring of several cardiac functions by nurses and physicians, but there’s currently no singular, convenient device on the market that can measure the most vital aspects of a patient’s cardiovascular health.  Ramakrishna Mukkamala, professor of bioengineering at the University of Pittsburgh Swanson School of Engineering, and Aman Mahajan, ...

A team of international scientists has used NASA’s James Webb Space Telescope to detect a new carbon compound in space for the first time. Known as methyl cation (pronounced cat-eye-on) (CH3+), the molecule is important because it aids the formation of more complex carbon-based molecules. Methyl cation was detected in a young star system, with a protoplanetary disk, known as d203-506, which is located about 1,350 light-years away in the Orion Nebula. Carbon compounds form the foundations of all known life, ...

Philadelphia, June 26, 2023 – Along with all global sectors, the dairy industry is working to reduce its environmental impact as we look toward a shared 2050 net zero future. Research is currently focused on greenhouse gas mitigation strategies that do not compromise animal health and production, but many discussions maintain that a radical transformation—involving reducing animal-based foods and increasing plant-based foods—is needed in our agriculture production systems in order ...

A new study from the Department of Ethology, Eötvös Loránd University, showed that dogs may not equally benefit from observing the ‘helpful action’ of a human demonstrator in the classic detour around a V-shaped fence task. Those who are experienced with the world of ethological conferences, know all too well that if you present your work about dog behavior, the first (or second) question from the audience will be: “And did you check whether the breed of the dog had an effect on your results?” Actually, this is not surprising as most people are familiar with the mindboggling variability of hundreds of ...

FINDINGS Scientists at the UCLA Jonsson Comprehensive Cancer Center have identified potential new biomarkers that could indicate how someone diagnosed with metastatic melanoma will respond to immunotherapy treatment. The researchers found when T cells are activated, they release a protein called CXCL13, which helps attract more B cells and T cells to the tumor site. The B cells then show the T cells specific parts of the tumor, which leads to increased activation of the T cells and their ability to fight the cancer. This cooperation between T cells and B cells was associated with improved survival in patients diagnosed with metastatic melanoma ...

CHICAGO, June 26, 2023 – A new American Dental Association (ADA) clinical practice guideline suggests conservative methods to treat tooth decay in primary and permanent teeth could lead to better outcomes when used with common restorative materials like fillings or caps. An expert panel of dentists developed the first-ever guideline on this topic after extensive review of approximately 300 published studies. The guideline, published in the July issue of The Journal of the American Dental Association, contains 16 recommendations regarding treatment ...

Research shows that school suspensions do not deter but instead amplify future punishment, what has been termed labeling theory: the idea that the symbolic label that comes with a suspension shapes how others perceive students. But few studies have examined racial and ethnic differences in this process, even though critical race theory (CRT) suggests that the consequences of suspension likely differ across racial and ethnic groups due to stereotypes. In a new study, researchers examined how the relation between suspension and subsequent arrest differs for White, Black, and Hispanic students. They found that suspension ...

UNIVERSITY PARK, Pa. — In an attempt to rescue a rare darter in the lower Susquehanna River, a Penn State research team, working with the Pennsylvania Fish and Boat Commission, has determined that the fish is a distinct subspecies found nowhere else. And that makes the effort to restore its population even more important, the researchers say. A yellow- to olive-colored member of the darter family with dark bars often arrayed in zebra fashion, the Chesapeake logperch is typically just a few inches long, with a small mouth and a short, conical snout. It is believed to only ever have inhabited the lower drainages of the Susquehanna and Potomac rivers, and it has not been seen ...

A new study co-authored by Patrick Hill, associate professor of psychological and brain sciences, offers an important message for our times: A sense of purpose in life — whether it’s a high-minded quest to make a difference or a simple hobby with personal meaning — can offer potent protection against loneliness.  “Loneliness is known to be one of the biggest psychological predictors for health problems, cognitive decline, and early mortality,” Hill said. “Studies show that it can ...

Demand for modern biofuels is expected to grow substantially in order to mitigate climate emissions. However, they are far from being a climate neutral alternative to gasoline and diesel. A new study in Nature Climate Change shows that under current land-use regulations, CO2 emission factors for biofuels might even exceed those for fossil diesel combustion due to large-scale land clearing related to growing biomass. Before bioenergy can effectively contribute to achieving carbon neutrality, international agreements need to ensure the effective protection of forests and other natural lands by introducing carbon ...

The biological roots of autism continue to perplex researchers, despite a growing body of studies looking at an increasing array of genetic, cellular and microbial data. Recently, scientists have homed in on a new and promising area of focus: the microbiome. This collection of microbes that inhabit the human gut has been shown to play a role in autism, but the mechanics of this link have remained awash in ambiguity. Taking a fresh computational approach to the problem, a study published today in Nature Neuroscience sheds new light on the relationship between the microbiome and autism. This research — which originated ...

(COLUMBUS, Ohio) – Firearms are the leading cause of death among children and teens 1-19 years old in the United States.
