Study shows the importance of fluid flow in shaping the composition, activity of hydrothermal microbes

Most visitors to Paliochori Beach on the Greek island Milos may not be aware of the bay's shallow-water hydrothermal community, a veritable Greek salad of microbes, that is within snorkeling distance from the shoreline.

Researchers may have identified a key intermediate in the transition from prokaryotes to eukaryotes

All modern organisms fall into two classes, eukaryotes and prokaryotes. Eukaryotes (from the Greek meaning "true kernel") have a cell nucleus that harbors most of the cell's genetic information and includes organisms such as humans, plants and fungi.

Study highlights the importance of membrane composition of targeted cells

Bacteria, fungi, and yeast are very good at excreting useful substances such as weak acids. One way in which they do this is through passive diffusion of molecules across the cell membrane. At the same time, cells need to prevent leakage of numerous small molecules.

Researchers find a new way to penetrate the cell using boron clusters’ superchaotropic properties

The recent research by scientists from the Centre for Research in Biological Chemistry and Molecular Materials (CiQUS, USC), together with Jacobs University (Bremen, Germany), presents a new membrane carriers’ class that leaves behind the amphiphilic paradigm.

Novel method to sneak large drug-carrying biological molecules into cells

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a novel method of delivering drugs into human cells using large biological molecules, by first encasing them in a protein-based microdroplet.

Confocal laser scanning microscopy captures high-resolution 3D images of cell division in microalgae

Cell division ensures growth or renewal and is thus vital for all organisms. However, the process differs somewhat in animals, bacteria, fungi, plants, and algae.

Researchers gain detailed insight into the mechanism of a light-driven chloride pump

Many bacteria and unicellular algae have light-driven pumps in their cell membranes: proteins that change shape when exposed to photons such that they can transport charged atoms in or out of the cell.

Study offers insight into how activated protein C may protect aging patients from reperfusion injury

A University of South Florida Health (USF Health) preclinical study offers molecular insight into how activated protein C (APC) may improve aging patients' tolerance to reperfusion injury – a potentially adverse effect of treatment for ischemic heart disease.

Omicron variant inefficient in causing diseases than other COVID-19 variants, study reveals

Scientists from the Department of Microbiology at the University of Hong Kong (HK) have found that the Omicron variant of SARS-CoV-2 replicates less efficiently and causes fewer diseases than other variants of COVID19.

Researchers develop a three-dimensional, fully dynamic kinetic model of a living minimal cell

Scientists report that they have built a living "minimal cell" with a genome stripped down to its barest essentials – and a computer model of the cell that mirrors its behavior.

Research explains how E4 peptide exerts antifibrotic effect and what makes it so effective

A research team at the Medical University of South Carolina led by Carol Feghali-Bostwick, Ph.D., reports in the Journal of Clinical Investigation Insight that the E4 peptide reverses fibrosis, or scarring, in human and mouse tissues by activating an antifibrotic pathway that is common to all organ systems.

Pyroptosis is not a one-way ticket, it can be halted and controlled

A study published by researchers at the University of Illinois Chicago describes a new method for analyzing pyroptosis -; the process of cell death that is usually caused by infections and results in excess inflammation in the body -; and shows that process, long thought to be irreversible once initiated, can in fact be halted and controlled.

Scientists use fruit fly embryos to study immune cell invasion

To fight infections and heal injuries, immune cells need to enter tissue. They also need to invade tumors to fight them from within.

COVID-19 virus spreads through cell-to-cell transmission

The virus that causes COVID-19 has adopted some stealth moves to stay alive and kicking, and one secret to its success is hiding from the immune system by spreading through cell-to-cell transmission, a new study has found.
