Researchers have developed an implantable, bioabsorbable, wireless device that speeds recovery in rats by stimulating injured nerves with electricity. It accelerates the regrowth of nerves and enhances the recovery of muscle strength and control. The device, the size of a dime and thick as a paper, degrades in a few weeks. This new approach to treating peripheral nerve injury could mean a world to people with tingling, numbness, and weakness in their arms, hands, and legs.
The European Commission is about to recommend that EU member states abandon the practice of changing the clocks in spring and autumn.
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.
A group of major American hospitals established a nonprofit generic drug company, Civica Rx, to battle long-lasting shortages of critical medicines and their high prices. Their goals are providing stable supplies for 14 generic drugs used in hospitals and price transparency. This will allow hospitals to save time and money while providing patients with better health care.
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.
