Archaea are ubiquitous microorganisms whose evolution shaped the biosphere of Earth. Their evolutionary paths are truly fascinating. A great example is an ectosymbiotic lifestyle which is found among DPANN archaea. Archaea are ubiquitous microorganisms whose evolution shaped the biosphere of Earth.

Thousands of years ago, early hunter-gatherers returned regularly to Tagua Tagua Lake in Chile to hunt ancient elephants and take advantage of other local resources, according to a study published May 22 in the open-access journal PLOS ONE by Rafael Labarca of the Pontifical Catholic University of Chile and colleagues. Thousands of years ago, early hunter-gatherers…

Populations of canola plants genetically engineered to be resistant to herbicides can survive outside of farms, but may be gradually losing their engineered genes, reports a new study led by Cynthia Sagers of Arizona State University, US, published May 22 in the open-access journal PLOS ONE. Populations of canola plants genetically engineered to be resistant to…

In summer 2021, Badlands National Park was home to a healthy and growing population of Rocky Mountain bighorn sheep, with approximately 300 total among the three herds. Then in August, Paul Roghair, lead biological science technician for the park, came across a dead sheep. In September, he found a dead ram. Roghair had a sinking…

A famous Mycenaean suit of armor was not just ceremonial, but suitable for extended combat, according to a study published May 22 in the open-access journal PLOS ONE by Andreas Flouris of the University of Thessaly, Greece and colleagues. A famous Mycenaean suit of armor was not just ceremonial, but suitable for extended combat, according to…

The trees in the forest are not just a random group. Fascinating facts reveal pine tree family relationships. The pollen that floats in the air can spread for hundreds of kilometers, but the offspring are usually found in the neighborhood. The trees in the forest are not just a random group. Fascinating facts reveal pine tree…

The risk to public health from human feces in our rivers and seas will increase without action to create a wastewater system fit for the future, according to a Leeds academic. The risk to public health from human feces in our rivers and seas will increase without action to create a wastewater system fit for the…

The damage was unusual, experts say, because turbines are built to withstand extreme weather. Iowa is a wind powerhouse, with thousands of turbines. The damage was unusual, experts say, because turbines are built to withstand extreme weather.

Efficient communication between cells is vital for many biological processes, such as recruiting immune cells to combat disease. The rapid release of at least 80 signaling molecules, including tumor necrosis factor and epidermal growth factor, is controlled by a membrane-bound protease called ADAM17. Efficient communication between cells is vital for many biological processes, such as recruiting…
