Scleroderma, a chronic and currently incurable orphan disease where tissue injury causes potentially lethal skin and lung scarring, remains poorly understood.
However, the defining characteristic of systemic sclerosis, the most serious form of scleroderma, is irreversible and progressive scarring that affects the skin and internal organs.
Researchers have revealed the first atomic structures of the respiratory apparatus that plants use to generate energy, according to a study published today in eLife.
The 3D structures of these large protein assemblies - the first described for any plant species - are a step towards being able to develop improved herbicides that target plant respiration. They could also aid the development of more effective pesticides, which target the pest's metabolism while avoiding harm to crops.
A new study out of the University of Chicago and Stanford University on pairs of twins with and without food allergies has identified potential microbial players in this condition. The results were published on Jan. 19 in the Journal of Clinical Investigation.
BOZEMAN, Montana (January 19, 2021) - A four-year study recently published in Ecology and Evolution concludes that the fungal disease, white-nose syndrome, poses a severe threat to many western North American bats.
Since it was first detected in 2006, white-nose syndrome has killed millions of bats in eastern and central North America. The spread of the fungal pathogen that causes white-nose syndrome in hibernating bats has reached several western U.S. states, mostly likely through bat-to-bat spread, and is presently threatening western species.
Anyone who has tried and failed to meditate knows that our minds are rarely still. But where do they roam? New research led by UC Berkeley has come up with a way to track the flow of our internal thought processes and signal whether our minds are focused, fixated or wandering.
Using an electroencephalogram (EEG) to measure brain activity while people performed mundane attention tasks, researchers identified brain signals that reveal when the mind is not focused on the task at hand or aimlessly wandering, especially after concentrating on an assignment.
Editor's Note: In the fifth graf, the number of African savannah elephants left in the wild was updated to 415,000.
For the first time, scientists have successfully used satellite cameras coupled with deep learning to count animals in complex geographical landscapes, taking conservationists an important step forward in monitoring populations of endangered species.
People's fear of 5G technology is rational. Such technology does emit radiation, even if it's at low levels. But 5G isn't all that different from 4G, and it certainly doesn't cause COVID-19 despite such rumors having spread rapidly across the globe.
Researchers need to better understand how misinformation like this spreads in order to hone their intervention efforts and prevent misinformed perspectives from taking root. In society's virtual world, preventing technological misinformation, in particular, is important now more than ever.
BROOKLYN, New York, Tuesday, January 19, 2021 - The World Health Organization reports that as of January 19, 2021, there are approximately 94 million cases of COVID-19 globally, with over 2 million deaths. In the face of these numbers -- driven in part by an aggressive resurgence of the virus in the U.S.
Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun's flow of high-speed solar wind, detailed in new research published today in The Astrophysical Journal. This first look at relatively small features, dubbed "plumelets," could help scientists understand how and why disturbances form in the solar wind.
Following a series of studies on termite mound physiology and morphogenesis over the past decade, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have now developed a mathematical model to help explain how termites construct their intricate mounds.
The research is published in the Proceedings of the National Academy of Sciences.
The Tiger Rattlesnake possesses the simplest, yet most toxic venom of any rattlesnake species, and now new research from a team lead by a University of South Florida biologist can explain the genetics behind the predator's fearsome bite.
A new therapy developed by researchers at Rush University Medical Center is showing success as a way to prevent COVID-19 symptoms in mice.
Washington, DC - January 19, 2021 - Viral genome sequencing of wastewater can detect new SARS-CoV-2 variants before they are detected by local clinical sequencing, according to a new study reported in mBio, an open-access journal of the American Society for Microbiology. The ability to track SARS-CoV-2 mutations in wastewater could be particularly useful for tracking new variants, like the B.1.17 strain that is now widespread in the U.K. and has already been introduced in the U.S.
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.
