The banyan tree Ficus macrocarpa produces aerial roots that give it its distinctive look. A new study reveals the genomic changes that allow the tree to produce roots that spring from its branches. Credit: Photo by Gang Wang The banyan fig tree Ficus microcarpa is famous for its aerial roots, which sprout […]

Newly described chemical reaction could have assembled DNA building blocks before life forms and their enzymes existed.   ANIMATION Discovery boosts theory that life on our planet arose from RNA-DNA mix. Chemists at Scripps Research have made a discovery that supports a surprising new view of how life originated on our […]

An image obtained from the system showing barcoded bees inside the observation hive. Outlines reflect whether a barcode could be decoded successfully (green), could not be decoded (red), or was not detected (no outline). The hive entrance is in the lower-right corner, and the inset reveals two bees that were […]

ANIMATION Proof-of-concept study represents first successful attempt to reverse the aging clock in animals through epigenetic reprogramming. Scientists turned on embryonic genes to reprogram cells of mouse retinas. Approach reversed glaucoma-induced eye damage in animals. Approach also restored age-related vision loss in elderly mice. Work spells promise for using same […]

There are notable impacts on the biology of living things in the harsh environment of space. A team of scientists has now identified a possible […]

Adult female and juvenile Popa langur (Trachypithecus popa) in the crater of Mount Popa, Myanmar. Credit: Thaung Win A new primate species dubbed the Popa langur has been discovered in Myanmar after years of extensive study, including analysis of a 100-year old specimen kept in the London Natural History Museum.

ANIMATION For the first time, researchers describe how Rho protein really stops gene expression. New research has identified and described a cellular process that, despite what textbooks say, has remained elusive to scientists until now — precisely how the copying of genetic material that, once started, is properly turned off. […]

This multicolored image of chromatin was created using multiplexed fluorescence in situ hybridization and super-resolution microscopy. Credit: Xiaowei Zhuang lab High-resolution, 3D images of human chromosomes in single cells reveal how DNA structure might influence its function. In high school textbooks, human chromosomes are pictured as wonky Xs like two hotdogs jammed […]
