Researchers identified a structural loop in the SARS-CoV-2 spike protein, the area of the coronavirus that facilitates entry into cells, and a sequence of four amino acids in the loop that are different from other known human coronaviruses in this viral lineage. SARS-CoV-2 has some shared properties with the 2003 virus responsible for the SARS outbreak. The loop appears to be important to both the transmission and stability of the virus. The study also found that in addition to humans and primates, cats, ferrets, and minks are also susceptible to COVID-19 infection.
Biological sequencing of the fusion peptides of SARS-CoV and SARS-CoV-2 found them to be a 93% match. Calcium ions interacting with the fusion peptide alters the peptide's structure, and how it interacts with membranes to promote infection. The findings provide a potential target for antiviral development to treat coronavirus.
Researchers report a boost in healthy antioxidants for green tea brewed with bottled, as opposed to tap, water.
Researchers believe some treatments for mental health conditions may be ineffective, or even dangerous for left handed people. A new study reports areas of the brain housing alertness and determination may be on the right side for left dominant people. The new theory suggests the location of a person's neural system for emotion depends on their handedness.
A new study provides further evidence that increasing choline consumption during pregnancy has cognitive benefits for children.
Researchers report caffeinated drinks reduce our ability to taste just how sweet something is. Ironically, this makes us crave sweet tastes more.
