Mice run faster on high-grade oil

Between the 1932 and 2008 Olympic Games, world record times of the men's 100m sprint improved by 0.6 seconds due to improved training techniques and technological advances. Imagine if this improvement could be achieved by a simple change in diet. Scientists at the Research Institute of Wildlife E...

The faster they come

Being the neighbourhood bully has its obvious advantages, but it becomes useless if your authority is continuously being challenged. In many animal species, however, stable hierarchies are routinely formed in which some individuals seem to slip naturally into their dominant role whereas others res...

New wheat disease could spread faster than expected

CORVALLIS, Ore. Both plant and human diseases that can travel with the wind have the potential to spread far more rapidly than has been understood, according to a new study, in findings that pose serious concerns not only for some human diseases but also a new fungus that threatens global wheat p...

Shellfish and inkjet printers may hold key to faster healing from surgeries

Using the natural glue that marine mussels use to stick to rocks, and a variation on the inkjet printer, a team of researchers led by North Carolina State University has devised a new way of making medical adhesives that could replace traditional sutures and result in less scarring, faster recover...

New open-source software permits faster desktop computer simulations of molecular motion

Whether vibrating in place or taking part in protein folding to ensure cells function properly, molecules are never still. Simulating molecular motions provides researchers with information critical to designing vaccines and helps them decipher the bases of certain diseases, such as Alzheimer's an...

Ocean growing more acidic faster than once thought

University of Chicago scientists have documented that the ocean is growing more acidic faster than previously thought. In addition, they have found that the increasing acidity correlates with increasing levels of atmospheric carbon dioxide, according to a paper published online by the Proceedings...

New type of vaccines deliver stronger and faster immune response

A new vaccine principle is being developed by scientists at the University of Copenhagen which if it works to its full expected potential could help to save millions of lives and revolutionise current vaccine technology. The 'InVacc' platform, as it is known, represents an advance on the origina...

Emissions rising faster this decade than last

The latest figures on the global carbon budget to be released in Washington and Paris indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000. "This is a concerning trend in light of global efforts to curb emissions," says Global Carbon Project (GCP) Ex...

Wasps and bumble bees heat up, fly faster with protein-rich food

Good pollen makes bees hot, biologists at UC San Diego have found. Wasps warm up too when they find protein-rich meat, a separate experiment has shown. In both cases warmer flight muscles likely speed the insects' trips home, allowing them to quickly exploit a valuable resource before competito...

New membrane strips carbon dioxide from natural gas faster and better

A modified plastic material greatly improves the ability to separate global warming-linked carbon dioxide from natural gas as the gas is prepared for use, according to engineers at The University of Texas at Austin who have analyzed the new plastics performance. Like a sponge that only soaks up...

Big-brained animals evolve faster

Ever since Darwin, evolutionary biologists have wondered why some lineages have diversified more than others. A classical explanation is that a higher rate of diversification reflects increased ecological opportunities that led to a rapid adaptive radiation of a clade. A textbook example is Darwin...

New 3-D test method for biomaterials 'flat out' faster

A novel, three-dimensional (3-D) screening method for analyzing interactions between cells and new biomaterials could cut initial search times by more than half, researchers from the National Institute of Standards and Technology (NIST) and Rutgers University report in the new issue of Advanced Ma...

Cheaper, better disease treatments expected from faster approach to developing antibodies

A method of mass-producing disease-fighting antibodies entirely within bacteria has been developed by a research group at The University of Texas at Austin. The group led by Dr. George Georgiou developed the new antibody-production approach to improve upon processes used previously to identify n...

Does evolution select for faster evolvers?

It's a mystery why the speed and complexity of evolution appear to increase with time. For example, the fossil record indicates that single-celled life first appeared about 3.5 billion years ago, and it then took about 2.5 billion more years for multi-cellular life to evolve. That leaves just a bil...

Osteoarthritis may be sign of faster 'biological ageing'

Osteoarthritis, the degenerative inflammatory bone disease, may be a sign of faster "biological ageing," suggests research published ahead of print in the Annals of the Rheumatic Diseases. The authors base their findings on a study of almost 1100 people, aged between 30 and 79. Most of them were...

Birds going extinct faster due to human activities

Embryonic stem cells, prized for their astonishing ability to apparently transform into any kind of cell in the body, acquire their identities in part by interacting with their surroundings - even when they are outside of the body in a laboratory dish, University of Florida scientists report. Us...

Why nerve cells work faster than the theory allows

With accuracy unknown until now, researchers from the Max Planck Institute for Dynamics and Self-Organization and the Bernstein Center for Computational Neuroscience in Göttingen together with the neurophysiologist Maxim Volgushev from the Ruhr-Universität Bochum have analyzed, by which rules, the ...

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...

Picking particles faster than one at a time

Computer scientists and biologists at the Department of Energy's Lawrence Berkeley National Laboratory have developed software that can select tens of thousands of high-quality images of biological molecules from electron microgaphs, rapidly and automatically, with accuracy approaching that of expe...

Jefferson biologist coaxing human embryonic stem cells to make dopamine with simpler, faster method

For clinicians, the ability to look routinely inside the body and see -- at the level of the cell -- how it confronts disease is a distant dream. But in a series of experiments with genetically engineered mice, a team of researchers from the Howard Hughes Medical Institute (HHMI) at the University ...

Mosquito study shows new, faster way West Nile can spread

Researchers at the University of Texas Medical Branch at Galveston (UTMB) have discovered a quick new way that mosquitoes can pass West Nile virus to each other. The new study challenges fundamental assumptions about the virus' transmission cycle and may help explain why it spread so rapidly across...

Neanderthal teeth grew no faster than comparable modern humans'

Recent research suggested that ancient Neanderthals might have had an accelerated childhood compared to that of modern humans but that seems flawed, based on a new assessment by researchers from Ohio State University and the University of Newcastle . They found that the rate of tooth growth pres...

'Green' energy from algae

...Apart from CO 2 -neutral closed loop management, algae have an-other advantage: Industrial CO 2 emissions may be used as a "re-source", as algae grow faster at high carbon dioxide concentrations and, hence, produce more biomass for energy production. However, this is not their only advantage: "Compared ...

On the other hand, generating EβC emitting maize varieties by means of gene technology may have advantages: it is faster and prevents the loss of other important traits.
