Giant bacteria found in Guadeloupe mangroves challenge traditional concepts

At first glance, the slightly murky waters in the tube look like a scoop of stormwater, complete with leaves, debris, and even lighter threads in the mix. But in the Petri dish, the thin vermicelli-like threads floating delicately ...

Scientists develop synergistic antibacterial carbon dots

The use of antibiotics helps fight bacterial infection, but the abuse of antibiotics has resulted in the emergence and widespread prevalence of "super bacteria," making the treatment of infectious diseases a worldwide problem ...

Researchers discover intracellular biosilicification in prokaryotes

Biosilicification—the formation of biological structures composed of silica—has wide distribution among eukaryotes. It plays a major role in global biogeochemical cycles and has driven the decline of dissolved silicon in ...

New 'decision aid' for CRISPR immune responses

Friend or foe? Immune systems constantly face this question. They must recognize and clear foreign invaders without eliciting autoimmunity. Prokaryotic CRISPR-Cas systems recognize invaders based on genetic sequence. But ...

A new method for the fast detection of a key antiviral

Interferons are proteins that constitute an important part of our natural defense systems. These proteins also exhibit a remarkable antiviral activity. The recombinant human interferon α2b (rhIFNα2b) was approved by the U.S. ...

Uncovering an evolutionary process that enabled diversity of plant life on Earth

About 1.2 billion years ago a blue-green bacterium was engulfed by a more complex cell, transforming our planet and allowing a tremendous diversity of plant life to emerge and continue to evolve.

Chromatin found to have originated in ancient microbes one to two billion years ago

In almost every human cell, 2 meters of DNA has to fit within a nucleus that is just 8 millionths of a meter wide. Like wool around a spool, the extreme space challenge requires DNA to wrap around structural proteins called ...

Ancient microorganisms found in halite may have implications for search for life

Primary fluid inclusions in bedded halite from the 830-million-year-old Browne Formation of central Australia contain organic solids and liquids, as documented with transmitted light and UV-vis petrography. These objects ...
