Chernobyl frogs exposed to radiation show no signs of accelerated aging or increased stress hormone levels
The radiation levels experienced by the frogs living in Chernobyl have not affected their age or their rate of aging. These two traits do not differ, in fact, between specimens captured in areas with high levels of radiation ...

Symmetry in biology: A look into how bees actively organize nests in mirroring patterns
Mirroring the mechanisms that make human faces and bodies—and those of many multicellular organisms—symmetrical, bee colonies build symmetrical nests when they are placed on either side of a double-sided comb. The finding, ...

RNA-targeting CRISPR reveals that hundreds of noncoding RNAs are essential—not 'junk'
Genes contain instructions for making proteins, and a central dogma of biology is that this information flows from DNA to RNA to proteins. But only two percent of the human genome actually encodes proteins; the function of ...

Plant engineering method promises to dramatically improve biofuel and bioproduct development
The ability to genetically engineer plants is largely thanks to a microscopic helper: a bacterium called Agrobacterium tumefaciens. Agrobacterium in the wild causes damaging tumors in flowering plants, including some economically ...

Spiders forage for prey rich in specific nutrients depending on species, life stage and sex
A new field study of arachnid hunting behavior has shown that spiders forage for prey rich in specific nutrients, and their preferences depend on the individual spider's species, life stage and sex. The results suggest that ...
