AI method predicts retention times of small molecules more reliably

Whether in drug discovery, environmental analysis or metabolomics: anyone analyzing complex biological samples often needs to identify the small molecules they contain. Researchers at Friedrich Schiller University Jena, in ...

Eye-eating amoeba resists treatment—understanding its biochemistry could help

In water, soil and air all around us lives a free-living, single-celled organism called Acanthamoeba. Most of the time, Acanthamoeba keeps to itself. On rare occasions, though, the amoeba infects humans and can cause severe ...

Asgard archaea suggest crawling motility may be far older than previously thought

Asgard archaea, our closest known microbial relatives, play a key role in current models of the origin of more complex organisms, known as eukaryotes (all animals, plants, protists and fungi). However, their biology has so ...

Wild crabapples have genetic potential to improve domestic varieties

A bad apple doesn't always ruin the bunch. In fact, it might make the bunch a little stronger. A new study published in Horticulture Research by Ben Mansfeld, an assistant professor of biology in Arts & Sciences at Washington ...

Whole genome duplication shaped the evolution of the salmon family

Evolution is driven by changes in DNA that sometimes promote adaptation, altering traits like disease resistance or reproduction. Often, these changes are minuscule, modifying a single letter in the DNA code—somewhat like ...

When microbial DNA is scarce, new profiling method helps separate genuine signals from contamination

In acute, life-threatening infections, rapidly characterizing the microorganisms in a patient sample can help guide diagnosis and treatment. Computational methods known as taxonomic profilers can analyze metagenome sequencing ...

Exposed ends and bends attract DNA-cutting enzymes, live imaging reveals

Researchers at the Nano Life Science Institute (WPI-NanoLSI) at Kanazawa University have directly visualized how enzymes find and break DNA molecules in real time. Using high-speed atomic force microscopy, the team followed ...

Shared DNA switch turns on genes in both bacteria and yeast

Microbial cell factories that produce pharmaceutical ingredients and other useful compounds include both the bacterium Escherichia coli and yeast, the organism used to leaven bread and ferment alcohol. The two organisms turn ...

Worm experiments reveal how epigenetic effects persist across generations

Every cell in an organism contains the same DNA, which carries all the instructions needed for it to function. Yet cells do not all use the same genes: A nerve cell, for example, does not activate the same genes as a muscle ...

One of Canada's worst invasive species may have arrived naturally

Most invasive species are introduced into the areas where they become damaging. That's part of why they tend to be so successful in taking over new environments and causing billions of dollars in damage.
