Iraq's marshes show progress toward recovery

...to those in one marsh that remained undrained. The fast recovery of plant production, overall good water quality, and rapid restoration of most wetland functions seem to indicate that the recovery of ecosystem function is well under way. Richardson and Hussain are not complacent about the marshes' future...

Scientists elucidate the kinome of key model organism

...tion and compile data about genes and kinases in a fast and efficient way, which can be very useful for drug discovery and development. According to Dr. Smith, Dictyostelium provides a simple model in which to study conserved cellular processes, and illuminates a period in the evolutionary history of t...

Taking evolution's temperature: Researchers pinpoint the energy it takes to make a species

... In the end, it is individual metabolic rate - how fast an organism burns food relative to its body weight - that primarily determines evolutionary rate. And higher environmental temperatures help increase metabolism. "Diversity is the hallmark of the living. Understanding the principles underlying the g...

Engineered heart tissue offers insights into irregular heartbeats, defibrillator failure

...ycardia -- a condition characterized by abnormally fast beating of the heart's pumping chambers. In particular, they sought to understand how such arrhythmia may lead to ventricular fibrillation, in which the heart's electrical activity becomes disordered, causing the ventricles to flutter rather than syn...

FDA approves first medical device using rutgers biomaterial

A new way of looking at molecular motors

...t involves a large number of motors that work very fast in neatly arranged teams, quickly letting go of the track once they have completed their "power stroke." Most molecular motors have a head, a neck (which powers movement), and a tail. Myosins usually look like two-headed snakes, kinesins like hairp...

Gene-specific Ebola therapies protect non-human primates from lethal disease

...arfield. "With Ebola infection, the virus grows so fast that it overtakes the host immune system. What we did, essentially, was to hold off the viral replication long enough for the host to mount an immune response and clear the virus." Working with a class of compounds known as antisense phosphorodiami...

Scientists seek to unwrap the sweet mystery of the sugar coat on bacteria

...oat the bacteria. The microarray technique worked fast enough that the researchers were able to see the sugar coating change over time in the neonatal meningitis strain of E. coli. "Over time, the lectins lost their ability to see these bacteria," says Mahal. "This demonstrates that our system is able t...

Why nerve cells work faster than the theory allows

Faster immune system testing set to improve poultry quality

...92 Molecular Tests project has developed a simple, fast and easy-to-apply test to assess the robustness of the immune system in poultry. The test can be performed in two days on blood samples from poultry houses, using equipment already available in poultry diagnostic laboratories. Current immune system t...

'Executive' monkeys influenced by other executives, not subordinates

...said Shepherd. "Low-ranking macaques are extremely fast to follow gaze, while the high-ranking monkeys were pretty blasé about it, being slower to respond." Said Platt, "So, now we have an excellent model of how temperament or status can modulate the strength of these two seemingly independent attention ...

Invasive species harms native hardwoods by killing soil fungus

Seedlings grown in sterilized, AMF-free soil taken from invaded and pest-free locations showed similar reductions, suggesting that diminished microbial activity had suppressed tree growth. Other experiments showed that adding ga...

Cortex matures faster in youth with highest IQ

Youth with superior IQ are distinguished by how fast the thinking part of their brains thickens and thins as they grow up, researchers at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) have discovered. Magnetic resonance imaging (MRI) scans showed that their brai...

Portable cocaine sensor developed at UC Santa Barbara

Elaine plans to continue her studies in the sciences, either in biochemistry or biology. McCall Wood said, "I'm really excited about this work. It let me know what res...

UCSD study finds anthrax toxins also harmful to fruit flies

...ns are active in fruit flies, suggesting that this fast breeding laboratory animal could also be used to determine the function of a variety of bacterial and viral pathogenic factors." Anthrax bacterium secretes three toxins, including LF and EF, and is only known to infect mammals. Because fruit flies ...
