The "power plants" of living cells, the mitochondria, probably evolved through endosymbiosis: A bacterium migrated into a primordial cell and eventually developed into an organelle that provides the cell with energy, among other things. Mitochon
阅读全文A trio of environmental specialists at the National Institute for Environmental Studies, in Japan, has found that Japanese honeybees sometimes resort to slapping ants with their wings to prevent their entry into their nest.
阅读全文Peek inside the human genome and, among the 20,000 or so genes that serve as building blocks of life, you'll also find flecks of DNA left behind by viruses that infected primate ancestors tens of millions of years ago.
阅读全文When trying to understand the present, it's helpful to look to history. New research from the University of Nebraska–Lincoln examined the fossil record going back 66 million years and tracked changes to mammalian ecosystems and species diversity on the N
阅读全文Researchers have uncovered an under-the-sea phenomenon where coral-destroying crown-of-thorns starfish larvae have been feasting on blue-green algae bacteria known as "sea sawdust."
阅读全文The most threatened reef fish are also the most overlooked by scientists and the general public. That is the startling finding of a team of scientists led by a CNRS researcher.
阅读全文Lice have been found feeding on the skin and blood of free-range chickens, which are infected at much higher rates than caged flocks. This finding could have implications for states like California, where all egg production is cage-free.
阅读全文A flock of migrating geese glides through the summer sky in an unmistakable "V" formation… a thundering herd of bison rumbles across the plains as a formidable group... and a massive school of sardines swims mesmerizingly in unison.
阅读全文Cut marks on fossils could be evidence of humans exploiting large mammals in Argentina more than 20,000 years ago, according to a study published July 17, 2024 in the open-access journal PLOS ONE by Mariano Del Papa of National University of La Plata, Arg
阅读全文A UC Riverside environmental engineering team has discovered specific bacterial species that can destroy certain kinds of "forever chemicals," a step further toward low-cost treatments of contaminated drinking water sources.
阅读全文In the depths of remote Antarctic lakes, communities of microorganisms are thriving where few life forms can survive. Scientists are studying structures formed by these communities to understand more about microscopic life in these extreme environments, w
阅读全文A team led by UT Southwestern Medical Center researchers has discovered a new way that cells regulate senescence, an irreversible end to cell division. The findings, published in Cell, could one day lead to new interventions for a variety of conditions as
