Dire warning on contamination of water and COVID-19 spread

A recent report by scientists in the United Kingdom and Poland and published on the preprint server medRxiv in June 2020 describes the presence of stable severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in water for up to 25 days, with the risk of infection by the contaminated water varying by the country’s environment.

Prior infection provides protection against SARS-CoV-2 virus in hamsters

In an animal model for COVID-19 that shares important features of human disease, scientists at the University of Wisconsin–Madison, the University of Tokyo and the Icahn School of Medicine at Mount Sinai show that prior infection with the SARS-CoV-2 virus provides protection against reinfection, and treatment with convalescent serum limits virus replication in their lungs.

Special time-locked encoding mechanism may have evolved for human speech

Humans can effortlessly recognize and react to natural sounds and are especially tuned to speech. There have been several studies aimed to localize and understand the speech-specific parts of the brain, but as the same brain areas are mostly active for all sounds, it has remained unclear whether or not the brain has unique processes for speech processing, and how it performs these processes.

Dust mite allergens activate well-known inflammatory factor to trigger allergies

A research team at MedUni Vienna, working in cooperation with the Johns Hopkins University in Baltimore, has discovered how certain dust mite allergens activate a well-known inflammatory factor - serum amyloid A protein -and can thus "trim" the lung tissue "in the direction of allergy".
