Bones at the nanoscale

...real time. The high brilliance of the X-ray source enabled the tracking of bone deformation in real time. Researchers could look at two length scales: on one side they observed the 100 nanometers sized fibres, and on the other, the crystallites embedded inside the fibre, which are not bigger than 2 to 4 ...

Novel experiment documents evolution of genome in near-real time

...eir entire genomes as a way to find mutations that enabled faster growth. After six days of growth, mutations appeared in the gene for an enzyme that initiates the process of enzymatically breaking down glycerol. Cells with mutations in the so-called glycerol kinase gene grew 20 to 60 percent faster than t...

Light wine intake is associated with longer life expectancy in men

...usually change during life," Streppel said. "This enabled us to study the effects of long-term alcohol intake on mortality." Researchers found that the number of alcohol users nearly doubled from 45 percent in 1960 to 85 percent in the 2000 survey. Average alcohol consumption rose and then fell at various ...

2,000 influenza virus genomes now completed and publicly accessible

...edicine. Recently, growing sequencing capacity has enabled the production rate to increase to more than 200 viral genomes per month. Eclipsing today’s milestone of 2,000 genomes, the microbial sequencing center will continue to rapidly sequence more influenza strains and isolates and will make all the sequen...

Prehistoric mystery organism verified as giant fungus

...organisms grew so large, "I’ve wondered whether it enabled Prototaxites to distribute its spores widely, allowing it to occupy suitable marshy habitats that may have been patchily distributed on the landscape," Hotton said. The relatively simple Devonian ecosystems certainly seemed to contain nothing to p...

Gene study shows three distinct groups of chimpanzees

.... The extent of accumulated genetic difference enabled the researchers to speculate about when the different populations separated. They estimate that bonobos, which live south of the Congo River, split off from the ancestors of modern chimpanzees about 800,000 years ago. Western chimps appear to have se...

Applied scientists create wrinkled 'skin' on polymers

...areas exposed to the beam are affected, the method enabled the scientists to create a variety of patterns--from simple one-dimensional wrinkles to peculiar and complex hierarchical nested wrinkles--along desired paths. Specific examples to date include "S" shapes, circular patterns, and long horizontal chann...

New research shows that flu is a trigger of heart attacks

...re receiving flu vaccines or statin drugs, so this enabled us to see what happened naturally in the absence o... on autopsy reports rather than death certificates enabled us to be much more accurate about the cause of death, because doctors often neglect to list flu on a...

Tracing broken wiring in stroke patients

... the brains of the stroke patients. The study also enabled new insights into how this disruption contributes to spatial neglect. Particularly important was that the FC MRI studies showed that the lower the functional connectivity of these regions, the more impaired the patients were in perceiving the negl...

Scripps research study reveals structural dynamics of single prion molecules

...uorescence bursts from individual tagged proteins, enabled the scientists to determine that the proteins being studied were, in fact, single monomers and not aggregates. Deniz said that future work with yeast prion mutants might resolve some of the questions that remain unanswered. "Our laboratory has sp...

Beyond the DNA: Chemical signatures reveal genetic switches in the genome

...d to known promoters and enhancers. These findings enabled us to generate computational algorithms that identified hundreds of novel genomic regions with regulatory potential." Moreover, says Heintzman, this 'histone code' was able to accurately distinguish between promoters, from which gene transcription is...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

...etter tolerated," McMahon said. The finding was enabled by recent genetics technology that allows researchers to scan, in a single experiment, thousands of genes for variations. Everyone has the same genes, but variations in them influence whether or not a person gets a specific disease. In this study, ...

Protein enables discovery of quantum effect in photosynthesis

...cterium that lives in extremely high temperatures, enabled the researches to discover that quantum mechanical effects appear to play a role in photosynthesis. The taco shell protein is arguably the most studied and understood protein in a complex photosynthesis researchers refer to as the antenna system,...

454 sequencing identifies HIV drug resistance at early stage

...uencing were found to be extremely important as it enabled the prediction of early antiretroviral treatment failure with strong statistical significance. “Current genotypic resistance technology available to clinicians is limited to detecting resistance mutations that are present at levels of approximately ...

Plastic that grows on trees

...cellulose. The solvent, called an ionic liquid, enabled the metal chlorides to convert the sugars to HMF. Ionic liquids provide an additional benefit: It is reusable, thus produces none of the wastewater in other methods that convert fructose to HMF. Metal chlorides belong to a class of ionic-liquid-so...

Nurtured chimps rake it in

...d chimpanzees correctly chose the rigid rake which enabled them to obtain the reward, indicating that both of these groups understood the physical properties of the two different rakes. The researchers then presented the same two groups with two identical ‘hybrid’ rakes. Each rake head had a rigid side m...

Research team identifies new Alzheimer's gene

...d without Alzheimer’s disease than ever before has enabled researchers to identify a common gene that appears to increase a person’s risk for developing Alzheimer’s disease. The finding, announced today by researchers at the Translational Genomics Research Institute (TGen), Banner Alzheimer’s Institute, Kron...
