New technique expands tissues so hundreds of biomolecules can be seen inside cells

For biologists, seeing is believing. But sometimes biologists have a hard time seeing. One particularly vexing challenge is seeing all the molecules in an intact tissue sample, down to the level of single cells, simultaneously. ...

Genomic study maps nearly 60 million years of apple genus evolution and diversity

A new comparison and analysis of the genomes of species in the genus Malus, which includes the domesticated apple and its wild relatives, revealed the evolutionary relationships among the species and how their genomes have ...

Gene syntax shown to control variability in synthetic plasmids

Engineers and biologists at Dartmouth College have found that, just like word order affects meaning in a sentence, the placement of genes within a plasmid—known as gene syntax—can influence how strongly each gene is expressed, ...

Oil cleanup agents do not impede natural biodegradation, research reveals

Using spill-treating agents to clean up oil spills does not significantly hinder naturally occurring oil biodegradation, according to a new study. The research, published in Applied and Environmental Microbiology, provides ...

Microplastics discovered in caddisfly casings from the 1970s suggest long-term contamination

A team of biologists working at the Naturalis Biodiversity Center, a research museum in the Netherlands, has found evidence of caddisfly larvae using microplastics to build their casings as far back as the 1970s.

Novel bacterial strain expands options for more sustainable soybean production

Brazil is the world's largest producer of soybeans and one of the reasons is the incorporation of bio-inputs, microorganisms that promote biological nitrogen fixation. Without this practice, this essential nutrient would ...

A genetic basis of adaptive evolution: Complex chromosomal rearrangements drive color changes in stick insects

Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether adaptive evolution relies on many mutations with ...
