Hundreds of feet below Earth's surface, rocks and water teem with fungi and support complex ecosystems of tiny organisms, according to a University of Michigan study that finds fungi are far more abundant deep underground than researchers previously thought.

Remembering the past can help living organisms make better decisions, but memory comes at a cost. Whether it is an animal searching for food or a single cell responding to its surroundings, storing and using information requires energy and resources. So, when is memory worth the

Social amoebae are unicellular organisms that act in concert, requiring extensive communication. Pierre Stallforth and colleagues studied modes of communication among cells of the social amoeba Dictyostelium discoideum, using fluorescent labeling and various imaging techniques.

Gene editing is a highly precise and powerful technology that allows scientists to insert, delete, modify or replace DNA bases in living organisms. It has a variety of uses, including correcting disease-causing mutations and improving crops. Tools like CRISPR act as molecular sci

Modern research on secondary metabolites from microbes, plants and marine organisms has revealed a remarkable diversity of chemical structures and bioactivities with broad applications in biotechnology, agriculture and medicine. Most natural products are composed of primary bioge

Pesquisa da USP identifica microrganismos resistentes ao sal e à radiação e cria novo modelo para classificar formas de vida extremófilas O post Minas Gerais abriga “Marte” brasileiro que pode mudar estudos sobre vida extrema apareceu primeiro em Olhar Digital.

All cellular life—from humans to bacteria—possesses two layers of immunity: innate and adaptive. Scientists have long understood how these two types of immunity work together in higher organisms but not in the microbial world.

Researchers at the University of Vienna have discovered a key mechanism that enables sea anemones to regenerate into fully developed organisms from disorganized clusters of cells. The study, published in Nature Communications, shows that the so-called Notch signaling pathway cont

How do microorganisms orient themselves to find the optimal habitat? Scientists have thoroughly investigated so-called magnetotactic bacteria, which use the Earth's magnetic field as a biological compass. Some eukaryotic single-celled organisms—that is, more complex organisms lik

Scientists at Murdoch University have read the full genetic code of bacteria from the salt lakes of Wadjemup (Rottnest Island), giving them their clearest picture yet of how these tiny organisms could be used to make biodegradable plastic. Their research is published in the journ

The Great Salt Lake is separated by a 20-mile (32-kilometer) causeway into a super-salty north arm and a less-salty south arm, with each hosting distinct communities of extremophiles. These organisms mingle at a gap in the causeway, designed to regulate salinity, that has provide

NASA's PACE satellite captured the Black Sea glowing turquoise during its annual phytoplankton bloom. The vivid color comes from massive numbers of coccolithophores, microscopic organisms whose reflective shells brighten the water enough to be seen from space. An astronaut aboard
