Predicting success

... research groups, shows that this relationship can differ from one animal to the next, from one human to the next, and even from one tissue to the next in the same animal. Prof. Degani says that, ideally, the fluid pressure inside tumor tissues would be checked using the MRI method she and her team develo...

Evidence for omega 3 fats less conclusive than we thought, say experts

...s cannot say exactly why the results of this trial differ from the other large studies in this field. They therefore conclude that it is not clear whether long chain or short chain omega 3 fats (together or separately) reduce or increase total mortality, cardiovascular events, cancer, or strokes. UK guide...

Junk DNA may not be so junky after all

...cers around the RET gene because the DNA sequences differ too much. That drove the Hopkins researchers to seek and develop this new system, by which virtually any DNA sequence can be tested for its ability to turn on a marker gene in zebrafish embryos. The system is a significant advance over current metho...

Infused spleen cells found not to impact islet recovery and reversal of type 1 diabetes in mice

CU, USDA team to curb two invasive, poisonous vines

...that help provide more nutrients to plant roots -- differ in species and abundance in areas surrounding swallow-worts. "It could be that swallow-worts release chemicals that make an optimal environment for certain mycorrhizal fungi," said DiTommaso. Through the altered soil, or possibly because of chemica...

New DNA 'fingerprinting' technique separates hemp from marijuana

..., both belong to the species Cannabis sativa. They differ in levels of the psychoactive drug tetrahydrocannabinol (THC) but are otherwise difficult to tell apart. The technique holds promise for distinguishing different cultivars (domesticated plant lines) in U.S. criminal cases. It may also prove useful in...

University of Utah to help build bionic arm

...ate in clinical trials. Existing prosthetic arms differ from the arm the university will help develop. Current models have limited movements, such as bending the elbow and wrist and opening and closing the hand, while the new arm will be capable of about 20 different movements, including moving fingers in...

Both alcoholism and chronic smoking can damage the brain's prefrontal cortex

Current models have limited movements, such as bending the elbow and wrist and opening and closing the hand, while the new arm will be capable of about 20 different movements, including moving fingers in...

Laos ?a lost world for frogs

...new frogs, other than where they live and how they differ morphologically from other similar species. "Now that these species have been documented we can go back and start to learn something about their biology," said Bryan Stuart of the Field Museum, a co-author of the study. The American Museum of Natur...

Attractive birds more immune against bird flu

... attempted to explain why individuals of a species differ in appearance and why the choice of a mate is influenced by behaviour and appearance features that cannot reasonably be thought to have any usefulness. Therefore, they have begun to look more and more at the genetics behind what are called secondary ...

Less is more, gene study shows

...ans and chimps share most of their genes, yet they differ dramatically in many ways---their walk, the sizes of their brains and their capacities for speech and language, for example. Scientists would like to know how and when such differences arose, and new research from the University of Michigan shows h...

NHGRI announces new sequencing targets

...fact, the genomes of any two humans are thought to differ by several hundred insertions, deletions and inversions. The second plan will add DNA sequence to existing draft sequences of a number of primate species and add additional sequence information in regions of high biological interest within those ge...

Alzheimer's found to be mostly genetic

... Even identical twins, who share all their genes, differ in their vulnerability. The study found only a 45 percent concordance rate for identical male pairs. This means that of all pairs where one twin has Alzheimer's, 55 percent of the healthy twins either will never get the disease or will develop it lat...

ASU researchers find link between social behavior, maternal traits in bees

...emarkable that other physiological traits known to differ between the two strains also correlated with ovary size in the experiment. The success of Amdam's research could prove more far-reaching than just the evolution of bee social behavior--scientists can use the findings as a stepping stone when looking...

Food-crop yields in future greenhouse-gas conditions lower than expected

...ng CO2 levels, most plants grown in enclosures can differ greatly from those grown in farm fields, Long said. FACE has been the only technology that has tested effects in real-world situations, and, to date, for each crop tested yields have been "well below (about half) the value predicted from chambers," t...

Higher levels of obesity associated with greater health risks

...ortality, CHD mortality, and CHD incidence did not differ by race/ethnicity." "There was a positive trend in all-cause mortality risk and CHD incidence with increasing weight category. This trend had borderline significance for CHD mortality among black women, likely reflecting sample size limitations. Muc...

Evolution reveals an independent route for diversity in animal form

...erns of expression of the cnidarian Hox-like genes differ radically across the phylum and are inconsistent with the expression patterns exhibited by typical Hox-system genes. The authors conclude that the Hox system is an invention of higher animals (the Bilateria) and, therefore, is not a defining characte...

Learning the language of DNA

...broad range of start sites, individual species can differ subtly in the way they control these genes, meaning the genes can evolve faster, and organisms with these genes can become more complex. The consortium also found that many pseudogenes ?traditionally thought to be "fossils" of ancient genes ?are ac...

Results with newer bladeless LASIK equivalent to standard microkeratome LASIK

With record resolution and sensitivity, tool images how life organizes in a cell membrane

...ause they have the same number of protons but that differ in mass because they have a different number of neutrons. Isotopes do not change the chemical structure of the molecules that they label. In contrast, the dyes commonly used in biological studies for labeling change the structure of the molecules to ...
