Scientists from Denmark and the United States have discovered that norepinephrine plays a key role in brain cleansing: during sleep, the brainstem releases the molecule every 50 seconds, causing blood vessels to constrict and…
German physicists have detected a signal from the elastic coherent scattering of reactor antineutrinos by atomic nuclei using the germanium detector CONUS+. The statistical significance of the detection was 3.7 standard deviations. The results are available at…
I think everyone has heard of this drug, but not everyone understands how it actually works: Ozempic (the active ingredient is semaglutide) is a glucagon-like peptide-1 (GLP-1) mimetic. A mimetic is a substance…
Russian scientists have discovered a previously unknown bacteriophage, Sxt1, in a therapeutic phage cocktail for treating bacterial infections. It is capable of infecting a number of wild strains of E. coli resistant to phages from the same family. Comparing…
Gabriella Captur of University College London and colleagues analyzed available population-based cardiac MRI data and concluded that chronic exposure to aircraft noise at night is associated with…
Danish researchers conducted the world's first pilot clinical trials, which showed that fecal transplantation can significantly improve the condition of patients with gastroenteropathy associated with type 1 diabetes. A report on the study…
Bone damage occurs for many reasons, from trauma to congenital problems. Furthermore, the number of elderly people worldwide is rapidly growing, prone to bone loss and increased risk of fractures.
American and French researchers conducted a detailed clinical and histopathological analysis of the disease in a second patient who received a genetically modified pig heart and lived with it for nearly six weeks. He was found to have damage…
Lu Qi of Tulane University and colleagues conducted an observational study and found that drinking coffee in the morning was associated with lower all-cause and mortality rates.
Julia Marcus of Harvard Medical School and colleagues from Australia and the United States conducted a retrospective cohort study and found that post-exposure prophylaxis with doxycycline dramatically reduced the incidence of infections transmitted by…
Erina Hosoya and colleagues at Juntendo University conducted a retrospective analysis of data from 41 patients treated for B-cell lymphoma with the CAR-T drug tisagenlecleucel over three years. It showed that…
