Unveiling HIV's Hidden Entry Point for Targeted Antibodies

As the HIV virus approaches a human cell to dock and potentially deliver its lethal genetic code, there is a remarkably brief moment during which a tiny portion of its surface undergoes a rapid opening, initiating the infection process.

Bacteria Arrangement in Biofilm Influences Reaction to Antibiotics

Although bacteria are typically thought of as single-celled creatures suspended in liquids or dispersed sparsely across surfaces, their true mode of growth is in sticky clusters known as biofilms in many settings.

Honeybees Directly Provide Nutrients to Gut Bacteria

Bacteria have adapted to all terrestrial environments. Some have evolved to survive in the gut of animals, where they play an important role for their host; they provide energy by degrading indigestible food, they train and regulate the immune system, they protect against invasion by pathogenic bacteria, and they synthesize neuroactive molecules that regulate the behavior and cognition of their host.

Unlocking the Gut's Metabolic Secrets

The variety of enzymes that microbes employ to make energy in the low-oxygen environment of the gut is highlighted by a survey of bacterial genomes.

Zipping Up Chromosomes: The Synaptonemal Complex Revealed

We have two copies of each chromosome in every cell in our bodies except in our reproductive cells. Sperm and egg cells contain a single copy of each chromosome with a unique mix of genes from our parents, an evolutionary trick to give our offspring genetic variability.

ADSC-Exos and BMSC-Exos Protect Retinal Ganglion Cells From Hydrostatic Pressure Damage

Mesenchymal stem cells (MSCs) have protective effects on the cornea, lacrimal gland, retina, and photoreceptor cell damage, which may be mediated by exosomes (exos) released by MSCs.

Structural Insights Unmask Novel Adaptations and Functions of Human LINE-1 ORF2

Martin Taylor, MD, PhD, a physician investigator in the Department of Pathology at Massachusetts General Hospital and an instructor in Pathology at Harvard Medical School, is the lead corresponding author of a new study in Nature, Structural Analysis and Inhibition of Human LINE-1 ORF2 Protein Reveals Novel Adaptations and Functions.

Cryo-EM Analysis Uncovers Unexpected Enzymatic Switch in Bacterial Anti-Phage System

Scientists have revealed a never-before-seen phenomenon in a protein: Alone, the enzyme processes DNA and RNA but, when bound to another protein as part of a defense system, interacts with a completely different type of compound to help bacteria commit suicide.

Structural Insights Into Coronavirus Spike Proteins

Coronaviruses employ protein “spikes” to latch onto and infect cells. Contrary to their name, these spikes do not have a rigid and pointed structure. Instead, they resemble chicken drumsticks, with the meaty portion facing outward.

Where Does the Light Come From? Optical Properties Allow Plants to “See” Light

An innovative study led by Professor Christian Fankhauser at UNIL and colleagues at EPFL has combined expertise in biology and engineering to reveal that a light-sensitive plant tissue uses the optical properties of the air-water interface to create a light gradient that is ‘visible’ to the plant.
