Food scientists from Cornell University have developed a test for rapid detection of E. coli in drinking water using genetically-engineered bacteriophages. It can be administered locally in hard-to-reach areas around the world and provides results within hours. Obtaining quick and accurate results is a current bottleneck in preventing infection and could save many.
Researchers from Stanford have identified human skeletal stem cells that become bone, cartilage, or stroma. Cells were recovered from fetal and adult bone marrow and were also derived from induced pluripotent stem cells. This discovery will open up new therapeutic possibilities.
Australian researchers have shown for the first time that laser therapy can be used to alter the population of gut bacteria in mice. The findings, if confirmed in humans, could help in the treatment of diseases such as diabetes.
Almost 20 years ago the human genome, 3 billion DNA base pairs long, was first sequenced. Despite all the progress researchers still know little about how the genome is organized within cells. Now researchers from the University of Illinois at Urbana-Champaign have developed a new technique that can create a 3D image of the genome’s organization.
Researchers from the University of Copenhagen used a new advanced technique to identify a protein that is responsible for cellular memory transfer in cell division. The finding is decisive for a fresh view and understanding of development from one cell to a whole body.
Researchers from The University of Toledo have found the chemical reason behind why blue light damages our eyes over time, contributes to macular degeneration, and can even cause blindness. Since we’re spending more time in front of screens than ever before, this finding might be a big step forward toward preventing eyesight deterioration.
Two separate research groups used CRISPR gene editing to fuse entire sets of brewer’s yeast chromosomes together, resulting in two strains with just one and two chromosomes. Surprisingly, the changes had little effect on most functions of the yeast. Their findings could be monumental to the study of chromosomes and why their numbers vary from species to species.
Researchers from the University of Tennessee Institute of Agriculture presented a concept of houseplants as aesthetically pleasing and functional alarm systems of home health. They have effectively connected two seemingly unrelated disciplines – plant sciences and architectural design. Genetically engineered houseplants could detect viruses, such as influenza virus, odors, and other volatile organic compounds that plants can “inhale” through their leaves.
Researchers from the University of California tested gene-drive technology in mice. This controversial application of CRISPR, capable of altering the genomes of entire species, has been applied to mammals for the first time. Although the developed technology has a long way to go before being used for pest control in the wild, it could be useful in basic research.
Zebrafish have become the animal model of choice for research in many areas. Now, researchers from Rice University trace roots of cancer development using genetically modified zebrafish. These fish produce fluorescent tags in migratory embryonic nerve precursor cells, enabling them to trace neuroblastoma and other forms of cancer.
