Magnetic brain stimulation
Boston MA (SPX) Mar 13, 2015 -
Researchers at MIT have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles - a technique allowing direct stimulation of neurons, which could be an effective treatment for a variety of neurological diseases, without the need for implants or external connections.
The research, conducted by Polina Anikeeva, an assistant professor of ...

Small eddies produce global effects on climate change
Sydney, Australia (SPX) Mar 18, 2015 -
The increasing strength of winds over the Southern Ocean has extended its ability to absorb carbon dioxide, effectively delaying the impacts of global warming.
New research published in the Journal of Physical Research found the intensifying wind over that ocean increased the speed and energy of eddies and jets, which are responsible in large part for the movement of nutrients, heat and sa ...

Chimpanzees will travel for preferred foods, innovate solutions
Chicago IL (SPX) Mar 18, 2015 -
Just as humans will travel to their favorite restaurant, chimpanzees will travel a farther distance for preferred food sources in non-wild habitats, according to a new study from scientists at Chicago's Lincoln Park Zoo that publishes on March 17 in the journal PeerJ.
Chimpanzees at Lincoln Park Zoo prefer grapes over carrots. Previous research at the zoo provided that insight into food pr ...

Gulf of Mexico marine food web changes over the decades
Washington DC (SPX) Mar 18, 2015 -
Scientists in the Gulf of Mexico now have a better understanding of how naturally-occurring climate cycles - as well as human activities - can trigger widespread ecosystem changes that ripple through the Gulf food web and the communities dependent on it, thanks to a new study published Saturday in the journal Global Change Biology.
A team of NOAA scientists spent three years reviewing over ...

Predicting the extent of flash flooding
Washington DC (SPX) Mar 18, 2015 -
Devastating floodwaters such as those experienced during Iowa's Flood of 2008 - which swamped many Iowa communities, along with ten square miles of Cedar Rapids - are notoriously difficult to predict.
So a team of University of Iowa mathematicians and hydrologists collaborating with the Iowa Flood Center set out to gain a better understanding of flood genesis and the factors impacting it. ...

New genetic evidence resolves origins of modern Japanese
Oxford UK (SPX) Mar 12, 2015 -
Was there a single migration event or gradual mixing of cultures that gave rise to modern Japanese?
According to current theory, about 2,000-3,000 years ago, two populations, the hunter-gatherer Jomon from the Japanese archipelago, and the agricultural Yayoi from continental East Asia, intermingled to give rise to the modern Japanese population.
However, some researchers have suggest ...

Design and build of synthetic DNA goes back to 'BASIC'
London UK (SPX) Mar 18, 2015 -
A new technique for creating artificial DNA that is faster, more accurate and more flexible than existing methods has been developed by scientists at Imperial College London. The new system - called BASIC - is a major advance for the field of synthetic biology, which designs and builds organisms able to make useful products such as medicines, energy, food, materials and chemicals.
To engin ...
