by Jenni Ho, University of Kentucky Fig 1. Ovarian cancer cell lines exhibit varied responses to paclitaxel treatment. Paclitaxel-resistant (PacR) and parental control ovarian cancer cell lines, TOV-21G and OVCAR3, were treated with serially diluted doses of paclitaxel for 96 hours in vitro. Cell viability is displayed at each concentration tested relative to untreated cells for...

The report by the Centers for Disease Control and Prevention (CDC) came...

By Michael Irving September 27, 2021 A microscope image of peptide droplets that can self-replicate, which may represent protocells that arose along the path to life Muneyuki Matsuo, Hiroshima University Exactly how life first emerged from non-living matter is one of the most enduring mysteries of science. In a new study, Japanese scientists have created self-replicating protocells...
By Sally Robertson, B.Sc. Sep 27 2021 Researchers in the UK and Germany have provided evidence for a novel mechanism by which severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – binds to human host cells. The team – from the Wellcome Sanger Institute in Cambridge, the...
Almost every living thing on Earth—from bacteria to plants to people—have a circadian rhythm, the biological clock that controls both physiology and behavior of organisms over a 24-hour period. This internal timekeeping has been the subject of intense study for decades (the discovery of the genes that drive it led to the Nobel Prize in...
