Blood Protein Changes May Unravel Long COVID Mysteries
Long COVID was identified in blood proteins, an analysis of longitudinal data suggested. Blood samples from long COVID patients showed changes to blood serum proteins at 6 months that indicated activation of the immune system’s complement cascade, altered coagulation, and tissue injury, reported Onur Boyman, MD, of the University of Zurich in Switzerland, and co-authors […]
Early tastings shorten breastfeeding
The earlier infants begin to taste small samples of solid food, the earlier they eat more food and stop breastfeeding. This is shown in a new study from Uppsala University and Sophiahemmet University, in which the mothers of 1,251 infants from all over Sweden participated. Almost half of the infants received tastings at the age […]
How Long Has Polio Been Circulating in the U.S.?
The fact that poliovirus was detected in New York City wastewater samples as far back as April of this year shouldn’t be surprising, as the virus likely has been circulating for longer and more widely than previously believed, several experts told MedPage Today. “I think you’re gonna see over the next weeks more and more […]
Deadly Bacteria in U.S. Soil Not Tied to Lab Leak, Aromatherapy
The melioidosis-causing bacteria recently detected in U.S. soil samples is not likely related to a 2014 “lab leak” in Louisiana, nor to a recent outbreak sparked by an aromatherapy product, experts said. Genetic sequencing indicated the strain of Burkholderia pseudomallei detected in southern Mississippi is from the Western hemisphere, similar to isolates found in the […]
New insights about surface, structure of asteroid Bennu: OSIRIS-REx data indicates surface, near-subsurface rubble is loosely bound
When NASA’s OSIRIS-REx spacecraft collected samples from asteroid Bennu’s surface in 2020, forces measured during the interaction provided scientists with a direct test of the poorly understood near-subsurface physical properties of rubble-pile asteroids. Now, a Southwest Research Institute-led study has characterized the layer just below the asteroid’s surface as composed of weakly bound rock fragments […]
