Devices that monitor the human body's processes are being researched and tested for biological sensing or for prosthetics but materials scientists at the University of Washington have taken that a step farther.  They have built a transistor that uses protons and could communicate directly with living things. But the current prototype has a silicon base and could not be used in a human body, so don't get prepared to cyberpunk yourself just yet.

Currently sensing technology typically uses electrons, negatively charged particles, rather than protons, which are positively charged hydrogen atoms, or ions, which are atoms with positive or negative charge. 

Think someone is bored if they yawn? Perhaps their brain is just overheating.

A study led by Andrew Gallup, a postdoc in Princeton University's Department of Ecology and Evolutionary Biology, says yawning frequency varies with the seasons and that people are less likely to yawn when the heat outdoors exceeds body temperature.  Conclusion: yawning could serve as a method for regulating brain temperature.

$65 billion is is the increase in net farm income, the farm level benefit after paying for the seed and its biotech traits, that the biotech industry has provided across the globe during the period 1996 to 2009, according to an analysis published in the International Journal of Biotechnology.

The study's authors estimate that almost half of that money was derived by farmers in the developing world.

The number of individuals who are obese and suffer with its associated health problems has continued to rise, even being called an epidemic.

Is it genetics?  The dream of cheap food finally being realized? Or are we slaves to marketing?

Researchers from Yale University School of Medicine and the University of Southern California say they have visualized differences in the way that the brains of obese and non-obese individuals respond to visual cues of high-calorie foods.  They see those foods differently.

Massachusetts implemented health care reform to increase employer-based insurance and to provide no-cost or low-cost insurance to those unable to afford it but it hasn't worked - the uninsured in Massachusetts remain predominantly the working poor, according to a new study by researchers at Harvard Medical School.
