Researchers at Linköping University, Sweden, have developed a proton trap that makes organic electronic ion pumps more precise when delivering drugs. The new technique may reduce drug side effects, and in the long term, ion pumps may help patients with symptoms of neurological diseases for which effective treatments are not available. The results have been published in Science Advances.
(Singapore--January 29, 2021 9:35 a.m. SPT/January 28, 2021 8:35 p.m. EST)--Two radiation oncology trials presented at the IALSC World Conference on Lung Cancer Singapore highlight how some researchers are exploring use of higher radiation boost doses to only PET-positive regions in locally-advanced non-small cell lung cancer (NSCLC). A previous large RTOG phase III trial revealed that the unform delivery of a high dose to the entire tumor led to poorer survival.
CAMBRIDGE, MA -- In many ways, our brain and our digestive tract are deeply connected. Feeling nervous may lead to physical pain in the stomach, while hunger signals from the gut make us feel irritable. Recent studies have even suggested that the bacteria living in our gut can influence some neurological diseases.
What The Study Did: This study investigated how unemployment insurance and a $600 per week federal supplement to unemployment insurance were associated with food insecurity among people in low- and middle-income households who lost jobs during the COVID-19 pandemic.
Authors: Julia Raifman, Sc.D., of the Boston University School of Public Health, is the corresponding author.

In 2017, the Nobel Prize in Physiology or Medicine went to three scientists who uncovered the molecular mechanisms that control the circadian rhythm, otherwise known as the "wake-sleep" cycle. To carry out their work, the scientists used the common fruit fly Drosophila melanogaster, making this the sixth Nobel to be awarded to research involving it.

CHICAGO (January 29, 2021): Trauma patients and patients who need emergency surgery have little to no opportunity to get acquainted with the surgeon and team that will perform their operation. However, a large study has found that effective and meaningful physician communication is a more important contributor to the overall satisfaction of trauma patients and those having emergency surgery than it is for patients admitted to the hospital for medical reasons or for elective procedures.
An international team of scientists, coordinated by the Seville Institute of Biomedicine (IBiS) and the University of Seville has solved one of the hitherto unresolved enigmas of basic biology: how exactly do lipids distribute proteins within a cell? To do this, they used a new, completely innovative microscopy technology, which they applied to "mutant" cells they designed in their laboratory.
Knowledge about health is a cornerstone in a child's development of physical and psychosocial health.
Since 2016, around 25,000 pupils in years 4-6 in 86 of Denmark's municipalities have taken part in the project "11 for Health in Denmark", an 11-week exercise and health education programme offered to all schools in a collaboration between the University of Southern Denmark and the Danish Football Association.
Research on manufacturing battery cells is gaining momentum - and there is a strong need, considering the future demand for energy storage: For the year 2030, global production of rechargeable batteries will double from today's 750 gigawatt hours (GWh) per year to 1,500 GWh. A recently published review article in the magazine "Nature Energy" on cell production of various battery types suggests that the currently established lithium-ion batteries (LIB) dominate the market of rechargeable high-energy batteries in the coming years.
The biological process of photosynthesis is found at the beginning of nearly all food chains. It produces oxygen to breathe and provides the energetic foundation for using biotechnological processes to synthesize biofuels and chemical feedstock. Therefore, researchers are particularly interested in rapidly growing cyanobacteria. These organisms use light as an energy source and can carry out photosynthesis, similar to plants. However, the required photosynthetic protein complexes bind many nutrients. Vanessa Krauspe and Prof. Dr.
New research by Mimi E. Lam (University of Bergen) just published in Humanities and Social Sciences Communications identifies and explores the impacts of salient viral or COVID-19 behavioural identities that are emerging.
Evidence is emerging that vitamin D - and possibly vitamins K and A - might help combat COVID-19. A new study from the University of Bristol published in the journal of the German Chemical Society Angewandte Chemie has shown how they - and other antiviral drugs - might work. The research indicates that these dietary supplements and compounds could bind to the viral spike protein and so might reduce SARS-CoV-2 infectivity. In contrast, cholesterol may increase infectivity, which could explain why having high cholesterol is considered a risk factor for serious disease.
This is the conclusion of a recent study by an international team of researchers, including Anne-Marie Elbe, Professor of Sports Psychology at Leipzig University. The finding is of social importance because experiences in adolescence in particular have a formative influence on attitudes and behaviour in later life.
(Boston)--There is a growing awareness of systematic inequality and structural racism in American society. Science and medicine are no exception, as evidenced by historical instances of discrimination and overt racism.
In a perspective piece in the Journal of the American Society of Nephrology, researchers from Boston University School of Medicine (BUSM), take an honest look at how the current practice of nephrology (kidney medicine) may have elements rooted in racist ideologies.
