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)....

80 Year Murder Mystery Solved DNA

Brett Smith for redOrbit.com - Your Universe Online While DNA analysis is often used to catch perpetrators of crimes, recent work from scientists at the University of Leicester has shown that the technology can be used to identify victims as well. Two researchers from the university, John Bond and Lisa Smith, were able to use genetic techniques to identify the victim of a homicide from 1930 that took place in the British town of Hardingstone. The body of the male victim was incinerated...

GenoVive Offers Weight Loss Strategies Tailored to Individuals' Genetic Profiles NEW ORLEANS, Jan. 3, 2014 /PRNewswire/ -- Losing weight is the most popular New Year's resolution for 2014, but research shows that only eight percent of people are successful in achieving their resolutions. People fall back into old habits and give up when they do not see immediate results. A new company, GenoVive, is seeking to change the way we look at eating using the latest gene-based technology....

A review of the computer simulations of nuclear DNA DNA carries out its activities "diluted" in the cell nucleus. In this state it synthesizes proteins and, even though it looks like a messy tangle of thread, in actual fact its structure is governed by precise rules that are important for it to carry out its functions. Biologists have studied DNA by observing it experimentally with a variety of techniques, which have only recently been supplemented by research in silico, that is to say,...

Developing DNA Barcode Libraries From Museum Collections
2013-12-30 13:26:26

Pensoft Publishers The ability to sequence the DNA of plants and animals has revolutionized many areas of biology, but the unstable character of DNA poses difficulties for sequencing specimens in museum collection over time. In an attempt to answer these issues, a recent study of 31 target spider species from the Naturalis Biodiversity Center in Leiden, discovers that both time and body size are significant factors in determining which specimens can produce DNA barcode sequences. The study...

DNA Barcodes Help Identify Palms
2013-12-30 13:01:17

Pensoft Publishers Reliable and cost-effective species recognition is the dream of many scientists, and has important applications. While the use of morphological features is often uncertain, and can lead to misidentification, species identification based on the composition of short DNA sequences -the so-called "DNA barcodes"- has proven to be the safest way to reach this goal, both in animals and in many groups of plants. Palms belonging to the genus Phoenix, including the...

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...
