Nanopore technique rapidly decodes long DNA strands
(Phys.org) —A low-cost technology may make it possible to read long sequences of DNA far more quickly than current techniques.
Biomedical research reveals secrets of cell behavior
(Phys.org) —Knowing virtually everything about how the body's cells make transitions from one state to another – for instance, precisely how particular cells develop into multi-cellular organisms – would be a major ...
Powerful gene-editing tool appears to cause off-target mutations in human cells
In the past year a group of synthetic proteins called CRISPR-Cas RNA-guided nucleases (RGNs) have generated great excitement in the scientific community as gene-editing tools. Exploiting a method that some bacteria use to ...
Glass-blowers at nano scale: Researchers use STM to change size of glass capillary tubes
Have you ever thrown into the fire - even if you shouldn't have - an empty packet of crisps? The outcome is striking: the plastic shrivels and bends into itself, until it turns into a small crumpled and blackened ...
Oh, my stars and hexagons! DNA code shapes gold nanoparticles
(Phys.org) -- DNA holds the genetic code for all sorts of biological molecules and traits. But University of Illinois researchers have found that DNA's code can similarly shape metallic structures.
New technology speeds up DNA 'rewriting' and measures the effects of the changes in living cells
Our ability to "read" DNA has made tremendous progress in the past few decades, but the ability to understand and alter the genetic code, that is, to "rewrite" the DNA-encoded instructions, has lagged behind. A new Weizmann ...
Researchers take steps toward fast, low-cost DNA sequencing device
Researchers at Oak Ridge National Laboratory and Yale University have developed a new concept for use in a high-speed genomic sequencing device that may have the potential to substantially drive down costs.
Animals that seem identical may be completely different species
Animals that seem identical may belong to completely different species. This is the conclusion of researchers at the University of Gothenburg, Sweden, who have used DNA analyses to discover that one of our ...
Researchers identifies gene associated with eczema in dogs
A novel gene associated with canine atopic dermatitis has been identified by a team of researchers led by professors Kerstin Lindblad-Toh, Uppsala university and Åke Hedhammar, SLU, Sweden. The gene encodes a protein called ...
Immature switchgrass could help cellulosic ethanol industry
(Phys.org)—A gene that keeps switchgrass forever young could have far-reaching implications for the development of the plant as a biofuel crop, according to U.S. Department of Agriculture (USDA) scientists.
New latent tuberculosis test promises to be cheap and fast
Biomedical engineers at UC Davis have developed a microfluidic chip to test for latent tuberculosis. They hope the test will be cheaper, faster and more reliable than current testing for the disease.
New hope for diagnosis and treatment of intractable pediatric brain tumors
Scientists have discovered oncogenes capable of driving growth of normal human brain stem cells in a highly malignant pediatric brain tumor. The research, published by Cell Press in the December issue of the journal Cancer Ce ...
Regulating hematopoietic differentiation
Blood cells originate from a small pool of hematopoietic stem cells (HSCs) through a complex process of differentiation steps that are tightly regulated at the transcriptional level. Dissecting the mechanisms ...
MSU researchers develop temperature-tolerant enzymes for advancing genetic manipulation tools
Researchers at Montana State University have found a method for creating more robust, temperature-tolerant enzymes that can be used as tools in the process of genetic manipulation.
