All the genome sequences of organisms known throughout the world are stored in a database belonging to the National Center for Biotechnology Information in the United States. As of today, the database has an additional entry: Caulobacter ethensis-2.0. It is the world’s first fully computer-generated genome of a living organism, developed by scientists at ETH

Many insect pollinator species are disappearing from areas of Great Britain, a new study has found. The research, led by the Centre for Ecology & Hydrology, measured the presence of 353 wild bee and hoverfly species across the country, from 1980 to 2013. It showed one third of species experienced declines in terms of areas in which

A team of engineers at the University of California, Berkeley and the Keck Graduate Institute (KGI) of The Claremont Colleges combined CRISPR with electronic transistors made from graphene to create a new hand-held device that can detect specific genetic mutations in a matter of minutes. The device, dubbed CRISPR-Chip, could be used to rapidly diagnose

A fungicide commonly used by the agricultural industry to protect grains, fruit and vegetables from mold damage seems to kill fungi by a previously uncharacterized mechanism that delivers a metabolic shock to cells, new research finds. The fungicide, fludioxonil, was originally devised to protect seeds during storage but was so effective at limiting mold damage

Bacteria may travel thousands of miles through the air worldwide instead of hitching rides with people and animals, according to Rutgers and other scientists. Their “air bridge” hypothesis could shed light on how harmful bacteria share antibiotic resistance genes. “Our research suggests that there must be a planet-wide mechanism that ensures the exchange of bacteria

Researchers from the University of Toronto’s Institute for Biomaterials and Biomedical Engineering (IBBME) and the Donnelly Centre have discovered a population of cells – dubbed to be “elite” – that play a key role in the process of transforming differentiated cells into stem cells. The finding has important implications for regenerative medicine. Stem cells have

In research that casts cells as curators of their own history, Dana-Farber Cancer Institute scientists have discovered that adult tissues retain a memory, inscribed on their DNA, of the embryonic cells from which they arose. The discovery led to one even more intriguing—that the memory is fully retrievable: under certain conditions, cells can play the

Food safety regulations increasingly pressure growers to remove hedgerows, ponds and other natural habitats from farms to keep out pathogen-carrying wildlife and livestock. Yet, this could come at the cost of biodiversity. New research published today in the Journal of Applied Ecology encourages the presence of dung beetles and soil bacteria at farms as they naturally suppress E.

Herpes viruses reactivate in more than half of crew aboard Space Shuttle and International Space Station missions, according to NASA research published in Frontiers in Microbiology. While only a small proportion develop symptoms, virus reactivation rates increase with spaceflight duration and could present a significant health risk on missions to Mars and beyond. NASA’s rapid viral

By targeting a protein found in the saliva of mosquitoes that transmit Zika virus, Yale investigators reduced Zika infection in mice. The finding demonstrates how researchers might develop a vaccine against Zika and similar mosquito-borne viruses, the study authors said. The research was published in Nature Microbiology. There is no current vaccine or therapy for Zika
