A typical endurance horse (Arabian breed) presented for a gait test before the start of the race to check locomotor soundness. During an endurance competition (100-160 km), horses must undergo veterinary inspection at the end of each 20 to 40 km loop to check their recovery and capacity to continue […]

The map shows the mean production for the year 2008 across the Laurentian Great Lakes region. Lake production values are scaled from low (blue) to high (red).

Engineers have developed a new way to generate tough, functional materials using a mix of bacteria and yeast similar to the “kombucha mother” used to ferment tea. Credit: Chenfu Hsing A symbiotic culture of specialized yeast and bacteria can generate tough materials able to perform a variety of functions. Engineers […]

Coral reefs, such as Los Jardines de la Reina, pictured, have microbes that may help protect the coral against certain nutrient imbalances. Credit: Robert Walker The bacteria scrub out nitrogen, potentially defending against certain nutrient overloads. Corals have evolved over millennia to live, and even thrive, in waters with few […]

Hydrothermally-active submarine volcanoes account for much of Earth’s volcanism and are mineral-rich biological hotspots, yet very little is known about the dynamics of microbial diversity […]

ANIMATION For the first time, researchers describe how Rho protein really stops gene expression. New research has identified and described a cellular process that, despite what textbooks say, has remained elusive to scientists until now — precisely how the copying of genetic material that, once started, is properly turned off. […]

Timeline of early eukaryotic evolution unveiled the mitochondrial acquisition occurred in a scenario of increasing complexity. Credit: Utrecht University, IRB Barcelona By analyzing duplicates of thousands of genes, researchers have reconstructed the evolutionary events leading to the creation of eukaryotic cells, the precursors to virtually all life you can see […]

The bacterial exposure experiment took place from 2015 to 2018 using the Exposed Facility located on the exterior of Kibo, the Japanese Experimental Module of the International Space Station.

The Pappy Lane wreck in Pamlico Sound, North Carolina. Credit: John McCord, Coastal Studies Institute Shipwrecks act as artificial reefs and provide a substrate and nutrients for a great diversity of microorganisms, which can contribute to either the deterioration or preservation of the ship. Precisely how diverse such communities are, […]
