Aussie meat ants may be invasive cane toad's Achilles' heel

... them eating small toads, so we suspected that there might be some kind of mismatch between the invader and its newly invaded range, for example something ... be used to snare invasive species elsewhere. "The end result of this mismatch between traits of metamorph cane toads, which evolved in the Americas, and ...

'Strained' quantum dots show new optical properties

... advanced color displays, and more efficient solar panels, Nie adds. A mismatch between the lattices of the semiconductors making up the inner core and ... blood." "Core-shell nanocrystals are all expected to have some lattice mismatch between the core and the shell, so the strain effect is a general ...

Global warming linked to caribou-calf mortality

... mammals. "Our work is the first documentation of a developing trophic mismatch in a terrestrial mammal as a result of climatic warming," said Post. "And the rapidity with which this mismatch has developed is eye-opening, to say the least." While Post and ...

Extraterrestrial platinum was 'stirred' into the Earth

... the variations in isotopic ratios of osmium with time. Osmium isotopes are widely used as tracers of mantle processes, but there has been a mismatch between signals from osmium and from other important isotopic tracer systems which has eluded explanation until now. Co-authors Dr Marco Fiorentini ...

Springer launches Food Security

... and (2) to address the means by which these constraints may be overcome. Food Security will cover the following topics: global food needs, the mismatch between population and the ability to provide adequate nutrition, global food potential, natural constraints to satisfying global food needs, ...

Key to function of dinosaur crests found in brain structure

... and nasal passages are," said Evans. "From there, the anatomy of these missing soft parts is easily interpreted." The CT scan results revealed a mismatch between the external shape of the crest and the internal shape of the nasal passages in closely related species, suggesting a special function for ...

Brain structure provides key to unraveling function of bizarre dinosaur crests

... and nasal passages are," said Evans. "From there, the anatomy of these missing soft parts is easily interpreted." The CT scan results revealed a mismatch between the external shape of the crest (which no doubt functioned as a visual display) and the internal shape of the nasal passages in closely ...

Duke team explains a longtime visual puzzler in new way

... was published in PNAS Early Edition online on October 13. Other explanations of the flash-lag effect have included theories that the effect is a mismatch between systems dedicated to the perception of speed and the perception of position, and also theories of how stimuli are integrated over time. ...

ORNL researchers analyze material with 'colossal ionic conductivity'

... for example, an electron. "The new layered material solves this problem by combining two materials with very different crystal structures. The mismatch triggers a distortion of the atomic arrangement at their interface and creates a pathway through which ions can easily travel," Varela said. Other ...

New electrostatic-based DNA microarray technique could revolutionize medical diagnostics

... in surface charge density as a result of specific DNA hybridization can be detected and quantified with 50-picometer sensitivity, single base-pair mismatch selectivity, and in the presence of complex backgrounds. Furthermore, our electrostatic detection technique should render DNA and RNA microarrays ...

Study: Fountain of youth for your heart?

... that is responsible for transporting fat into the contractile cells of the heart actually increases. Based on this finding, Dyck proposed that the mismatch between fat uptake and fat use in the heart could lead to an accumulation of fat in the heart resulting in an age-related decrease in heart function. ...

Dead clams tell many tales

... preliminary means of assessing human impact on ecosystems. The University of Chicago's Susan Kidwell explains how measuring the degree of live-dead mismatch could be used as an ecological tool in the Oct. 26 early online edition of the Proceedings of the National Academy of Sciences. "We affect ...

A study proposes a new universal rule to explain the equilibrium of plant populations

... The balance between longevity and birth rates in photosynthetic organisms is what keeps their populations stable. In the event of a serious mismatch between plant mortality and birth rates, these populations would either be driven to extinction (if death rates far exceeded births) or would outgrow ...

Research shows cord blood comparable to matched bone marrow

... Remarkably, mismatched cord blood performed as well as matched bone marrow as measured by leukemia-free survival rates, providing the degree of mismatch was limited and the number of cord blood cells available was sufficient. Furthermore, study participants who received matched cord blood had a 20 ...

Study shows lizard moms dress their children for success

... prey makes them hard to catch). But the genes that control behavior and back pattern are not linked, so a lizard could end up with a mismatch that would leave it highly vulnerable to predators--wearing stripes and trying to hide in the grass, for example. Lancaster identified two pathways ...

Mice with a migraine show signs of brain damage

... of oxygen, the brain’s demands for oxygen are suddenly so great that the blood vessels in the brain can’t keep up,?said Nedergaard. “It’s a mismatch between supply and demand.? Brain tissue closest to the oxygen-rich blood vessels soaks up the oxygen as fast as they can, leaving tissues ...

Applied scientists create wrinkled 'skin' on polymers

... the chemical composition of the polymer close to its surface and forms a thin stiff skin which wants to expand," explains Vaziri. "The consequent mismatch between the mechanical strain of the generated stiff skin and the underlying polymeric substrate, almost like a tug-of-war, buckles the skin and ...

Gene transfer using mutant form of good cholesterol cuts vascular plaque and inflammation

... to the female mice during a bone marrow transplant from male mice. Because male DNA carries a y chromosome and female DNA does not, the gender mismatch enabled the researchers to precisely track the donor bone marrow. To deliver the gene to the arterial wall, the researchers used a "signal ...

Enzyme crystal structure reveals 'unexpected' genome repair functions

... Fan of Scripps Research, the first author of the study, adds, "We were surprised when we found that XPB contains a domain structurally similar to the mismatch recognition domain of a bacterial DNA repair protein MutS. MutS helps recognize and repair mismatched DNA in E. coli. These two proteins have little ...

ASU researchers 'wire' DNA to identify mutations

... electronic states of DNA. By measuring the conductance, the team was able to understand the sequence information in the DNA and whether there was a mismatch in comparison to a normal DNA sequence. What they found was that just a single base pair mutation in a DNA molecule, such as substituting an A ...

Embryonic Stem Cells Treated With Growth Factor Reverse Hemophilia In Mice: UNC Researchers

... months after injection, mice still produced factor IX without immune suppression. This occurred even in mice that were a complete immunologic tissue mismatch to the PEPs. In addition, the incidence of teratomas was low." The researchers believe this study demonstrates the power of multidisciplinary ...
