University
of Iowa neuroscientist John Wemmie is interested in the effect of acid
in the brain. His studies using new magnetic resonance imaging
techniques suggest that increased acidity or low pH, in the brain is
linked to panic disorders, anxiety, and depression. But his work also
suggests that changes in acidity are important for normal brain activity
too.

The
U.S. government has been pushing doctors to e-prescribe, in part
because it can be safer for patients. Now, more than a third of the
nation's prescriptions now are electronic, and starting this year,
holdouts will start to see cuts in their Medicare payments.

Not
long after a partially paralyzed man in Switzerland used his mind to
remotely control a small robot, a Massachusetts woman paralyzed for 15
years used only her thoughts to direct a robotic arm to pick up a bottle
of coffee and bring it to her lips But will the experimental
brain-controlled technology ever help paralyzed people in everyday life?

As
valuable as X-ray mammography is, it has certain drawbacks, such as
exposure to ionizing radiation and the potential for false results. In
the first phase of clinical testing is a new imaging device built around
the principle of photoacoustics, or light-induced sound, that can
detect and visualize breast tumors with a high degree of targetting
accuracy.

An interdisciplinary team of engineers at the University of Arkansas
has developed a wireless health-monitoring system that gathers critical
patient
information, regardless of the patient's location, and communicates that
information in real time to a physician, hospital, or the patient
herself.

Online crowd-sourcing—in which a task is
presented to the public, who respond, for free, with various solutions
and
suggestions—has been used to evaluate potential consumer products,
develop
software algorithms, and solve vexing research and development
challenges. But
diagnosing infectious diseases?

On
Tuesday, a team at Switzerland's Federal Institute of Technology in
Lausanne used a simple head cap to record the brain signals of
Mark-Andre Duc, a partial quadriplegic at a hospital about 100 km away.
Duc's thoughts, or electrical signals, were decoded almost instantly by a
laptop at the hospital, which then relayed them to a foot-tall robot
that scooted around the laboratory.

A
new Northwestern University brain-machine technology delivers messages
from the brain directly to the muscles—bypassing the spinal cord—to
enable voluntary and complex movement of a paralyzed hand. The device
could eventually be tested on, and perhaps aid, paralyzed patients.

By
developing software that uses 3D models of proteins involved in cystic
fibrosis, a team of scientists at Duke University has identified
several new molecules that may ease the symptoms of the disease.
