The theory that pigeons’ famous skill at navigation is down to iron-rich nerve cells in their beaks has been disproved by a new study published in Nature.
The study shows that iron-rich cells in the pigeon beak are in fact specialised white blood cells, called macrophages. This finding, which shatters the established dogma, puts the field back on course as the search for magnetic cells continues. (more…)
*Berkeley Lab scientists part of team that analyzed 19 state-of-the-art climate models.*
While the worst drought since the Dust Bowl of the 1930s grips Oklahoma and Texas, scientists are warning that what we consider severe drought conditions in North America today may be normal for the continent by the mid-21st century, due to a warming planet.
A team of scientists from the Lawrence Berkeley National Laboratory (Berkeley Lab), Lawrence Livermore National Laboratory (LLNL), and the National Oceanic and Atmospheric Administration (NOAA) came to this conclusion after analyzing 19 different state-of-the-art climate models. Looking at the balance between precipitation and evapotranspiration—the movement of water from soil to air—they found that no matter how rainfall patterns change over the next 100 years, a warming planet leads to drought. Their results were published in the December 2011 issue of the American Meteorological Society’s Journal of Hydrometerology. (more…)
Armonk, NY, USA – 07 Jun 2011: IBM today announced that it will provide the microprocessors that will serve as the heart of the new Wii U™ system from Nintendo. Unveiled today at the E3 trade show, Nintendo plans for its new console to hit store shelves in 2012.
The all-new, Power-based microprocessor will pack some of IBM’s most advanced technology into an energy-saving silicon package that will power Nintendo’s brand new entertainment experience for consumers worldwide.

What exactly is going on in the Gulf of Mexico? When there are reports of media blackouts, then the natural reaction is to start investigating, and in the current environmental catastrophe, the more stones one turns, the more horrific the potential scenario becomes. While scare mongering is as pointless as it is dangerous, the truth remains that the media have the duty to inform.
