Allometric model shows human travel is closely related to spread of COVID-19 A new study, released on the medRxiv* preprint server, indicates that the spread of the coronavirus disease 2019 (COVID-19) is governed by power-law dynamics, suggesting that alternative modeling approaches need to be used to understand and predict its propagation. Earlier models based on exponential growth Most conventional modeling approaches to the transmission of COVID-19’s causative pathogen – severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – assume that its spread follows an exponential patt...

San Francisco's newest cocktail bar features plants, plants and more plants FacebookTwitterEmail Fresh plants will be used in the decor — and drinks — when Propagation opens on San Francisco’s Post Street this week.Propagation Millennials who’ve grown obsessed with plants over the past few years can now gawk at greenery over drinks at Propagation, a new garden-themed bar in San Francisco. Lush plants have become common decor inside restaurants for a while now, on trend with skyrocketing houseplant sales overall. During the pandemic, as people sought life wherever they could find it in...

A team of scientists from the USA recently developed a recombinant “Angiotensin converting enzyme 2 (ACE2) Triple Decoy” that can trap SARS-CoV-2 and prevent its propagation inside the host cell.

Apoptosis is an important mediator of pathogenesis in animal coronavirus infection Apoptosis is a form of programmed cell death, which occurs in cells that are irreparably damaged or in cells infected by some viruses. This mechanism is extremely important in limiting a virus’s replication and its spread to other neighboring cells. A new paper in the journal Lifepresents an early review of the viral factors involved in initiating and effecting apoptosis within infected cells. Colorized scanning electron micrograph of an apoptotic cell (blue) infected with SARS-COV-2 virus particles (red), i...

SARS-CoV-2 modulates host cell central carbon metabolism for reproduction A team of scientists from Sweden and India has recently characterized the host cell metabolic alterations associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Their findings reveal that SARS-CoV-2 modulates the host cell's central carbon metabolism to facilitate replication and infection propagation. Moreover, they observe that the severity of coronavirus disease 2019 (COVID-19) primarily depends on the blood levels of glucose, mannose, and glutamate. The study is currently available o...
