Project combines global online design challenge with lab experiments An enthusiastic group of non-experts, working through an online interface and receiving feedback from lab experiments, has produced designs for RNA molecules that are consistently more successful than those generated by the best computerized design algorithms, researchers at Carnegie Mellon University and Stanford University report. Moreover, the researchers gathered some of the best design rules and practices...

New Method Allows Researchers To Sort Out DNA Contamination
2014-01-28 06:53:19

April Flowers for redOrbit.com - Your Universe Online Special precautions are usually a part of retrieving ancient DNA to prevent DNA from researchers or the environment from mixing with that of the fossil. Many ancient fossils, however, have been lying forgotten in museum collections for decades that have become contaminated with present-day human DNA before even entering the laboratory. A solution for this problem, published in Proceedings of the National Academy of Sciences (PNAS),...

A simple adjustment to a powerful gene-editing tool may be able to improve its specificity. In a report receiving advance online publication in Nature Biotechnology, Massachusetts General Hospital (MGH) investigators describe how adjusting the length of the the guide RNA (gRNA) component of the synthetic enzymes called CRISPR-Cas RNA-guided nucleases (RGNs) can substantially reduce the occurrence of DNA mutations at sites other than the intended target, a limitation the team had previously...

(NYSE MKT: INO) today unveiled that the company has developed a new DNA-based cytokine immune activator, interleukin -33 (IL-33), that in combination with optimized DNA vaccines delivered by electroporation increased the potency and efficacy of the therapeutic response to the...

Our View On How Nature Is Structured Changed By DNA Barcodes
2014-01-21 14:11:58

University of Helsinki How you seek is what you find To understand how feeding interactions are structured, researchers from Finland and Canada chose to focus on one of the simplest food webs on Earth: the moths and butterflies of Northeast Greenland, as attacked by their specialist enemies, parasitic wasps and flies developing on their prey (called host), killing it in the process. "What we found in this system was mind-boggling", explains Helena Wirta, the lead author of the study....

New Imaging Technique Captures Vibrations Of Proteins, Tiny Motions Critical To Human Life
2014-01-16 15:44:38

University at Buffalo Like the strings on a violin or the pipes of an organ, the proteins in the human body vibrate in different patterns, scientists have long suspected. Now, a new study provides what researchers say is the first conclusive evidence that this is true. Using a technique they developed based on terahertz near-field microscopy, scientists from the University at Buffalo and Hauptman-Woodward Medical Research Institute (HWI) have for the first time observed in detail the...

Researchers Count Thousands Of Fish Using A Glass Of Water
2014-01-16 15:08:16

University of Washington A mere glass full of water from Monterey Bay Aquarium's 1.2 million-gallon Open Sea tank, among the 10 largest aquariums in the world, is all scientists really needed to identify the Pacific Bluefin tuna, dolphinfish and most of the other 13,000 fish swimming there. Researchers also for the first time used DNA from water samples to discern which of the species were most plentiful in the tank. Being able to determine the relative abundance of fish species in a...

Physical Reason For Shape Of Metaphase Chromosome Discovered
2014-01-15 07:37:00

Universitat Autonoma de Barcelona This work gives a solution to a fundamental question in structural biology: Why do metaphase chromosomes have their characteristic elongated cylindrical shape? The proposed solution is consistent with the structure of metaphase chromatin and with the nanomechanical properties of chromatin and chromosomes. It is a research at the interface between biology (higher order chromatin structure) and physical sciences (supramolecular structures and nanomaterials)....

Brief Introduction To DNA Probes
2014-01-12 00:00:00

DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic strength.” The Foundation for Genomics and Population Health website has a helpful video about...

Bacillus subtilis, also known as hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium commonly found in soil. It is rod-shaped and a member of the genus Bacillus. It also has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though recent research has proven this to not be strictly correct. It is not a human pathogen although...
