A unique catalyst paves the way for plastic upcycling

Posted: 26 May 2022 09:57 AM PDT

A recently developed catalyst for breaking down plastics continues to advance plastic upcycling processes. In 2020, scientists developed the first processive inorganic catalyst to deconstruct polyolefin plastics into molecules that can be used to create more valuable products. Now, the team has developed and validated a strategy to speed up the transformation without sacrificing desirable products.

Professional 'guilds' of bacteria gave rise to the modern microbiome

Posted: 26 May 2022 08:28 AM PDT

Even the smallest marine invertebrates -- some barely larger than single-celled protists -- are home to distinct and diverse microbial communities, or microbiomes, according to biologists. The study underscores that a vast diversity of animals have microbiomes, just as humans do. But more surprisingly, there's little correlation between how closely related most animals are and how similar their microbiomes are -- something widely assumed to be true based on the study of humans, larger mammals, and insects.

Study tracking T-cell activation over time boosts search for immune disease treatments

Posted: 26 May 2022 08:28 AM PDT

Researchers have identified links between 127 genes and immune diseases, providing newfound insights into the sequence and timing of gene activity during the activation of T cells, a key process in regulating the body's immune response.

Researchers hunt for one-pole magnets by combining cosmic rays and particle accelerators

Posted: 26 May 2022 08:28 AM PDT

Particle accelerators have helped researcher to draw new leading limits on the existence of magnetic monopoles from the collisions of energetic cosmic rays bombarding the Earth's atmosphere.

Fishing for new source of proteoglycans, an important health food ingredient

Posted: 26 May 2022 08:28 AM PDT

Chondroitin sulfate proteoglycans (CSPGs), commonly obtained from salmon nasal cartilage, are a key ingredient of various health foods. As the popularity of health foods increases, scientists are searching for alternative sources of CSPGs. Now, researchers have analyzed the PGs and their CS structures in the head cartilage of 10 edible bony fishes, including sturgeons. Their findings point to several new fishes that can serve as alternatives to salmon as a source of CSPGs.

Drug resistance molecule can spread though bacterial 'communities'

Posted: 26 May 2022 08:28 AM PDT

DNA molecules called plasmids -- some of which protect bacteria from antibiotics -- can spread rapidly through bacterial 'communities' that are treated with antibiotics, new research shows.

Breathing to win: Scientists show importance of screening breathing patterns in athletic populations

Posted: 26 May 2022 08:28 AM PDT

Dysfunctional breathing patterns are associated with a high risk of musculoskeletal conditions, resulting in poor physical performance. Now, a study has found that among athletes across age groups, there is a high prevalence of dysfunctional breathing patterns. Effective intervention strategies are required to restore normal breathing patterns and prevent injuries among athletes to ensure their superior performance and health.

3D in a snap: Next generation system for imaging organoids

Posted: 26 May 2022 08:28 AM PDT

A team of researchers has built a better system to quickly produce high-resolution 3D images in real time, providing a quantitative analysis of organoids.

Flash Joule heating process recycles plastic from end-of-life F-150 trucks into high-value graphene for new vehicles

Posted: 26 May 2022 08:28 AM PDT

Chemists have processed waste plastic from end-of-life trucks into graphene for composite materials in new vehicles.

Inappropriate antibiotics for nonhospitalized kids cost US at least $74 million

Posted: 26 May 2022 08:27 AM PDT

Children who were prescribed antibiotics inappropriately were more likely to develop complications such as diarrhea and skin rashes than children who were treated according to medical guidelines, according to a new study. This misuse of antibiotics resulted in at least $74 million in excess health-care costs in the U.S. in 2017.

Harnessing the immune system to treat traumatic brain injury in mice

Posted: 26 May 2022 08:27 AM PDT

Researchers have designed a targeted therapeutic treatment that restricts brain inflammation. The effectiveness of this approach in improving outcomes was demonstrated following brain injury, stroke or multiple sclerosis in mice. The system increases the number of regulatory T cells, mediators of the immune system's anti-inflammatory response, in the brain. By boosting the number of T regulatory cells in the brain, the researchers were able to prevent the death of brain tissue in mice following injury and the mice performed better in cognitive tests. The treatment has a high potential for use in patients with traumatic brain injury, with few alternatives currently available to prevent harmful neuroinflammation.

Gut bacteria can make blood pressure medication less effective

Posted: 26 May 2022 06:56 AM PDT

Hypertension, or high blood pressure, is a major risk factor for heart disease and stroke, two of the leading causes of death in America. It's also one of the most common chronic conditions in the United States, with nearly half of U.S. adults considered hypertensive under current guidelines. Among those with high blood pressure, an estimated 20% have what's known as resistant hypertension, meaning their blood pressure remains high despite aggressive treatment. New research has shown gut bacteria can reduce the effectiveness of certain blood pressure drugs, potentially providing a pathway to developing new ways of overcoming treatment-resistant hypertension.

Tsunami threats underestimated in current models

Posted: 26 May 2022 06:56 AM PDT

USC researchers have found a correlation between tsunami severity and the width of the outer wedge -- the area between the continental shelf and deep trenches where large tsunamis emerge -- that helps explain how underwater seismic events generate large tsunamis.

A nanoparticle and inhibitor trigger the immune system, outsmarting brain cancer

Posted: 26 May 2022 06:55 AM PDT

Scientists have fabricated a nanoparticle to deliver an inhibitor to brain tumor in mouse models, where the drug successfully turned on the immune system to eliminate the cancer. The process also triggered immune memory so that a reintroduced tumor was eliminated--a sign that this potential new approach could not only treat brain tumors but prevent or delay recurrences.
