You may have heard recently that pacemaker users going to sleep while using an Apple iPad and allowing it to fall to the chest can be harmed. It turns out that an iPad generates enough magnetism when laid on the chest to cause the pacemaker to enter "service" mode. In such a state, a pacemaker will pace at a "default" rate which may be different than your cardiologist has programmed. A defibrillator in that state will not deliver shock therapy.
The manufacturer of my defibrillator recommends keeping all household magnets at least 6 inches away from the device. For me, since it is at my left side, I should wear the club's magnetic name tag on my right side. Some people's device is in the abdomen, and would be more than 6 inches from a normal name tag location.
Once the magnet is removed, the device will exit service mode and resume normal operation.
But in any case, if you have a pacemaker or defibrillator, you should check with your cardiologist.

Scientists at University of Buffalo have discovered a protein in human breast milk that enhances the effectiveness of antibiotics. The effect is so strong that some antibiotic's dosage can be reduced by a factor of 8, and one fully-resistant bacterium can now be killed by antibiotics. Other organisms, such as the MRSA we've been hearing about lately, are easily killed. A summary can be seen at Science Daily.

Scientists at Massachusetts General Hospital have demonstrated an artificial kidney implanted in a rat, which was made from the rat's own cells, and which produced urine right away after implantation. The implications are that a person's kidney could soon be replaced by a bio-identical copy made especially for that person from his own cells in about two weeks. (Using the donor's own cells eliminates the problem of rejection.) Replacing other organs this way is also progressing. Read more here.

A Harvard University professor and a commercial pharmaceutical house have now definitively explained the anti-aging properties of red wine. It was already known to be due to the compound resveratrol, and it is now known how resveratrol works. This, in turn, has allowed even more effective compounds to be developed, and clinical trials are now underway. Resveratrol and these new compounds actually reverse aging in animals. A summary article can be found here.

This is Micki Carion-Shea and her dog Pluto. Pluto is her service dog. Here he sits patiently on Micki's lap as she plays duplicate bridge at NCBC. Pluto makes no comment or criticism about her play of the hand. We should all have partners like Pluto.

In a not-so-astonishing result, Duke University scientists have linked the brains of two rats hundreds of miles apart. Each rat both sent and recieved directly to and from its brain simple information transmitted over the internet between the U.S. and Brazil.
