When peaking at your brain may help with mental illness

Texas A&M University researchers have recently shown superior performance of a new oxide dispersion strengthened (ODS) alloy they developed for use in both fission and fusion reactors. Dr. Lin Shao, professor in the Department of Nuclear Engineering, worked alongside research scientists at the Los Alamos National Laboratory and Hokkaido University to create the next generation of high-performance ODS alloys, and so far they are some of the strongest and best-developed metals in the field. ODS alloys consist of a combination of metals interspersed with small, nanometer-sized oxide particles and are known for their high creep resistance. This means that as temperatures rise, the materials keep ...

Researchers at Baylor College of Medicine show that analysis of the proteomics, or all the protein data, from aggressive human cancers is a useful approach to identify potential novel therapeutic targets. They report in the journal Oncogene, the identification of "proteomic signatures" that are associated with clinical measures of aggressive disease for each of the seven cancer types studied. Some signatures were shared between different types of cancer and included cellular pathways of altered metabolism. Importantly, experimental results provided proof-of-concept that their proteomics analysis approach is a valuable strategy to identify potential therapeutic targets. "There are two notable aspects of this study. One is that ...

If you dunk a tea bag repeatedly into your mug or open a cream-filled cookie to lick the filling, you might find coping with pandemic isolation a bit easier than others. A UC Riverside-led study has found people who adopt unique rituals to make everyday tasks more meaningful might feel less lonely. "We found that something as simple as preparing tea in a certain way, as long as it's interpreted as a ritual, can make the experience more meaningful," said Thomas Kramer, a professor of marketing at UC Riverside's School of Business. "This makes people feel less lonely." The paper, published ...

Parkinson's disease has always been considered a brain disorder. However, new research reveals a close link between the disease and certain immune cells in the blood. Researchers from Aarhus University have taken the first step on a path which can lead to new ways of understanding and, in the long term, possibly treating this widespread disease that affects not only motor functions but also cognition and emotions. "We know that Parkinson's disease is characterized by an inflammation in the brain, and that this is crucial for the progression of the disease. But in the study, our interest has been focused on the immune cells found outside the brain," explains Marina Romero-Ramos, who is associate professor at the Department of Biomedicine at Aarhus University. The researchers ...

COVID-19 pandemic has increased loneliness and other social issues, especially for women, Mayo research finds ROCHESTER, Minnesota -- Social distancing guidelines have reduced the spread of COVID-19, but lockdowns and isolation also have created or aggravated other well-being concerns, reports new research. Mayo Clinic investigators found a significant increase in loneliness and a decrease in feelings of friendship during the pandemic. The study, published Feb. 20 in the journal Social Science & Medicine, also showed disproportionate negative effects among women and those with poorer health. The researchers say that while physical distance is important during the pandemic, distance within and among relationships can cause undue harm to a person's mental health and well-being. ...

Astronomers using the recently installed instrument MAROON-X on Gemini North have determined the mass of a transiting exoplanet orbiting the nearby star Gliese 486. As well as putting the innovative new instrument through its paces, this result, when combined with data from the TESS satellite, precisely measures key properties of a rocky planet that is ideal for follow-up observations with the next generation of ground- and space-based telescopes. The exoplanet-hunting instrument MAROON-X has obtained its first scientific result from its new home ...

What The Study Did: This randomized clinical trials reports that among adults with mild COVID-19, a five-day course of ivermectin, compared with placebo, didn't significantly improve the time to resolution of symptoms. The findings don't support the use of ivermectin for treatment of mild COVID-19, although larger trials may be needed to understand the effects of ivermectin on other clinically relevant outcomes. Authors: Eduardo López-Medina, M.D., M.Sc., of the Centro de Estudios en Infectología Pediátrica in  Cali, Colombia, is the corresponding author. To access the embargoed ...

In less than a second, a small sensor used in brain chemistry research can detect the key molecules that provide the genetic instructions for life, RNA and DNA, a new study from American University shows. The AU researchers believe the sensor is a useful tool for scientists engaged in clinical research to measure DNA metabolism, and that the sensor could be a quick way for lab clinicians to distinguish 'healthy' from 'sick' samples and determine if a pathogen is fungal, bacterial, or viral, before conducting further analysis. To explore whether the sensors could detect RNA and DNA, ...

The Pazyryk carpet is the world's oldest example of a knotted-pile carpet and is kept at the State Hermitage Museum in St. Petersburg, Russia. The carpet, which was made out of new wool at around 400 BC, is one of the most exciting examples of central Asian craftsmanship from the Iron Age. Ever since the carpet was discovered in 1947 by Russian archaeologists in a kurgan tomb in the Altai mountains, experts in traditional dyeing techniques have been puzzled by the vivid red, yellow and blue colours of the carpet, which lay buried in extreme conditions for almost two thousand five hundred years. Red fibres ...
