A new study from North Carolina State University shows that the inflammation caused by Clostridioides difficile (C. diff) infection gives the pathogen a two-fold advantage: by both creating an inhospitable environment for competing bacteria and providing nutrients that enable C. diff to thrive.
C. diff is a bacterium that causes diarrhea, often with severe or even fatal consequences. As part of its growth cycle, C. diff produces two toxins which cause inflammation and damage the lining of the gut.
As the air continues to dry and temperatures drop, the yearly battle against dry hands and skin has officially begun. New research from Northwestern University has found new evidence deep within the skin about the mechanisms controlling skin repair and renewal.
We should err on the side of caution and stop the global roll out of 5G (fifth generation) telecoms networks until we are certain this technology is completely safe, urges an expert in an opinion piece published online in the Journal of Epidemiology & Community Health.
There are no health concerns about 5G and COVID-19, despite what conspiracy theorists have suggested.
The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Université de Montréal have found.
This intriguing discovery by Ph.D. student Caroline Piaulet of UdeM's Institute for Research on Exoplanets (iREx) suggests that gas-giant planets form a lot more easily than previously believed.
Successive governments' approach to obesity policies has destined them to fail, say researchers.
Government obesity policies in England over the past three decades have largely failed because of problems with implementation, lack of learning from past successes or failures, and a reliance on trying to persuade individuals to change their behaviour rather than tackling unhealthy environments. This is the conclusion of new research by a team at the University of Cambridge funded by the NIHR School for Public Health Research.
Range anxiety, the fear of running out of power before being able to recharge an electric vehicle, may be a thing of the past, according to a team of Penn State engineers who are looking at lithium iron phosphate batteries that have a range of 250 miles with the ability to charge in 10 minutes.
Researchers at the University of Adelaide have found new evidence about the positive role of androgens in breast cancer treatment with immediate implications for women with estrogen receptor-driven metastatic disease.
Published today in Nature Medicine, the international study conducted in collaboration with the Garvan Institute of Medical Research, looked at the role of androgens - commonly thought of as male sex hormones but also found at lower levels in women - as a potential treatment for estrogen receptor positive breast cancer.
Cell velocity, or how fast a cell moves, is known to depend on how sticky the surface is beneath it, but the precise mechanisms of this relationship have remained elusive for decades. Now, researchers from the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) and Ludwig Maximilians Universität München (LMU) have figured out the precise mechanics and developed a mathematical model capturing the forces involved in cell movement.
UNIVERSITY PARK, Pa. -- Images of a protein involved in creating a potent antibiotic reveal the unusual first steps of the antibiotic's synthesis. The improved understanding of the chemistry behind this process, detailed in a new study led by Penn State chemists, could allow researchers to adapt this and similar compounds for use in human medicine.
Imagine going to a surgeon to have a diseased or injured organ switched out for a fully functional, laboratory-grown replacement. This remains science fiction and not reality because researchers today struggle to organize cells into the complex 3D arrangements that our bodies can master on their own.

A student infected with COVID-19 returning home from university for Christmas would, on average, have infected just less than one other household member with the virus, according to a new model devised by mathematicians at Cardiff University and published in Health Systems.
Variation in consumption of market-acquired foods outside of the traditional diet -- but not in total calories burned daily -- is reliably related to indigenous Amazonian children's body fat, according to a Baylor University study that offers insight into the global obesity epidemic.
A research team from the Institut national de la recherche scientifique (INRS) has developed a process for the electrolytic treatment of wastewater that degrades microplastics at the source. The results of this research have been published in the Environmental Pollution journal.
The spread of COVID-19 in Brazil overwhelmed the health systems in all the country's regions, particularly in areas where they were already fragile, according to a collaborative effort involving the Barcelona Institute for Global Health (ISGlobal), an institution supported by the "la Caixa" Foundation, the University of Sao Paulo, the Catholic University of Rio de Janeiro, the D'Or Institute of Research and Education and the Oswaldo Cruz Foundation.
