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 […]

Genes that give plant nucleus its shape discovered, also regulate copper tolerance. Researchers at the University of Tokyo have identified how the architecture of the cell nucleus can change gene activity in plants. This discovery reveals fundamental knowledge about genome regulation and points towards future methods for potentially manipulating the […]

A unique stress experiment aligned deoxygenation stress to the natural night-day cycle of common reef-building corals from The Great Barrier Reef. Credit: Morgan Bennett-Smith Ocean deoxygenation is now being recognized as major threat to future global coral reef survival. Oxygen is life, in or out of the water, raising concerns […]
