The photograph on the left shows the marine parchment tube worm (Chaetopterus sp.) under natural light. The worm is curled up, tucking its tail under…
Revealing yet another super-power in the skillful squid, scientists have discovered that squid massively edit their own genetic instructions not only within the nucleus of…
This transmission electron microscope image shows SARS-CoV-2 – the virus that causes COVID-19 – isolated from a patient in the U.S. The protrusions visible on…
Pictured is CIDER-Seq, a newly developed tool for sequencing circular and extrachromosomal circular DNA, in action. Credit: Devang Mehta New method will provide insight into…
In recent years, giant viruses have been unearthed in several of the world’s most mysterious locations, from the thawing permafrost of Siberia to locations unknown…
The exotic animal’s genome could point to possible treatment options for COVID-19 in humans. Similar to how a smoke detector sounds off an alarm, certain…
(A) Schematic representation of SARS-CoV-2, the viral spike protein and the cleavage sites for furin (green, S1/S2 position; the cleavage sequence is shown below the…
Discovery draws surprising parallels between low-level organisms and sophisticated neurons; lays the groundwork for memory-capable biological systems. Biologists studying collectives of bacteria, or “biofilms,” have…
Until now, scientists had assumed that there are about 80 so-called open reading frames (ORFs) in the genome of herpes simplex virus 1 (HSV-1). These…
Phylogenetic tree diagrams form the basis of understanding microbial evolution. Long branches between the two domains in some trees may reflect a period of very…
Researchers at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have identified a new mechanism that helps animals to develop with precise and…
Artists impression of “killing” the COVID-19 coronavirus. While shown to be effective in the lab environment, Ivermectin cannot be used in humans for COVID-19 until…
Using musical scores to code the structure and folding of proteins composed of amino acids, each of which vibrates with a unique sound. Credit: Markus…
This image shows a fold (shape) that may have been one of the earliest proteins in the evolution of metabolism. Credit: Vikas Nanda/Rutgers University Rutgers…
Immediately after a sperm fertilizes an egg, the SPRK1 enzyme leads the first step in untangling a sperm’s genome, kicking out special packing proteins called…
Hawaiian bobtail squid. Two genetic factors that control the expression of a key gene required by the luminescent bacteria that inhabit the squid’s light organs…

Approach focuses on 3D structures to simplify protein creation. Researchers have developed a process that could sharply reduce the work involved in computational protein design,…
Unlike what we commonly refer to as ‘genes’, phantom genes or ‘Long noncoding RNA’ (LncRNAs) do not lead to the production of proteins that our…
