Consumers of purchased foods have no way of ascertaining the quality and safety of the food that existing distribution systems deliver to their plates. Unfortunately, inappropriate refrigeration can sometimes lead to food spoilage, which is often difficult to detect. Such is the case for mackerel fish, which readily develop harmful levels of a substance called histamine when left at room temperature for too long. Histamine is neurotoxic and can trigger severe allergic reactions, including rashes, vomiting, and diarrhea.
LEBANON, NH - A joint team of researchers from Radiation Oncology at Dartmouth's and Dartmouth-Hitchcock's Norris Cotton Cancer Center (NCCC), Dartmouth Engineering, and Dartmouth-Hitchcock's Department of Surgery have developed a method to convert a standard linear accelerator (LINAC), used for delivery of radiation therapy cancer treatment, to a FLASH ultra-high-dose rate radiation therapy beam.
Two international studies confirm that for the majority of patients with respiratory infections who lose the sense of smell, this is due to COVID-19. The disease also often results in both loss of taste and the other senses in the mouth. A researcher from Aarhus University has contributed to the new results.
If you have had COVID-19, then forget about enjoying the smell of freshly made coffee. At any rate, two major international studies document that there is frequently a loss of smell and that this often lasts for a long time in cases of COVID-19
In a large-scale study of Danish children and young people, researchers from Aarhus University have for the first time found genetic variants that increase the risk of nocturnal enuresis - commonly known as bedwetting or nighttime incontinence. The findings provide completely new insights into the processes in the body causing this widespread phenomenon.
Scientists have shown that two species of seasonal human coronavirus related to SARS-CoV-2 can evolve in certain proteins to escape recognition by the immune system, according to a study published today in eLife.
The findings suggest that, if SARS-CoV-2 evolves in the same way, current vaccines against the virus may become outdated, requiring new ones to be made to match future strains.
ATLANTA--Early in the U.S. COVID-19 pandemic, unemployment claims were largely driven by state shutdown orders and the nature of a state's economy and not by the virus, according a new article by Georgia State University economists.
David Sjoquist and Laura Wheeler found no evidence the Payroll Protection Program (PPP) affected the number of initial claims during the first six weeks of the pandemic.
The offspring of older animals often have a lower chance of survival because the parents are unable to take care of their young as well as they should. The Seychelles warbler is a cooperatively breeding bird species, meaning that parents often receive help from other birds when raising their offspring. A study led by biologists from the University of Groningen shows that the offspring of older females have better prospects when they are surrounded by helpers.
Philadelphia, January 19, 2021 - Aged, wild-caught African green monkeys exposed to the SARS-CoV-2 virus developed acute respiratory distress syndrome (ARDS) with clinical symptoms similar to those observed in the most serious human cases of COVID-19, report researchers in The American Journal of Pathology, published by Elsevier.
ATLANTA--Georgia State University biology researchers have found that infecting the nasal passages of mice with the virus that causes COVID-19 led to a rapid, escalating attack on the brain that triggered severe illness, even after the lungs were successfully clearing themselves of the virus.
Assistant professor Mukesh Kumar, the study's lead researcher, said the findings have implications for understanding the wide range in symptoms and severity of illness among humans who are infected by SARS-CoV-2, the virus that causes COVID-19.
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.
