Bacteria use their own pumps to collect magnesium

Researchers at UiO and NCMM have discovered that the system used by bacteria to transport magnesium is so sensitive that it can detect a pinch of magnesium salt in a swimming pool.

Pacemakers with Internet connection, a not-so-distant goal

The healthcare sector is not escaping from the revolution in information and communications technologies. Thanks to the latest advances in microelectronics and communications technologies, it is not difficult to imagine a ...

Lipoic acid helps restore, synchronize the 'biological clock'

Researchers have discovered a possible explanation for the surprisingly large range of biological effects that are linked to a micronutrient called lipoic acid: It appears to reset and synchronize circadian rhythms, or the ...

Computer simulations reveal the energy landscape of ion channels

Every cell of our body is separated from its environment by a lipid bilayer. In order to maintain their biological function and to transduce signals, special proteins, so called ion channels, are embedded in the membrane. ...

Hold the phone for vital signs

An iPhone app that measures the user's heart rate is not only a popular feature with consumers, but it sparked an idea for a Worcester Polytechnic Institute (WPI) researcher who is now turning smart phones, and eventually ...

Taking mathematics to heart

Did you know that heart attacks can give you mathematics? That statement appears on the web site of James Keener, who works in the mathematics of cardiology. This area has many problems that are ripe for unified attack by ...

Can chaos theory help predict heart attacks?

Chaos models may someday help model cardiac arrhythmias -- abnormal electrical rhythms of the heart, say researchers in the journal CHAOS, which is published by the American Institute of Physics.
