Although embryonic stem cells have certainly grabbed most of the attention - and headlines - in the stem cell field in recent years, embryos aren't the only source of these versatile mother-cells. Political leanings aside, researchers are beginning to appreciate that many tissues in the body have their own stem cells. Blood cells, for example, derive from a single hematopoietic stem cell in the bone marrow, and now two groups of scientists from Boston report that they have identified a similar mother stem cell from which most heart cells arise. Working with mice, one group at Massachusetts General Hospital isolated...
...findings are certainly exciting - these stem cells could form the basis of new heart therapies, and could become a source of healthy, replacement cells for heart tissue damaged after a heart attack or by heart disease. But they represent only the first step in what will be a long road. First, the studies were conducted in mice and rats, and while these animals can serve as a template for understanding how heart cells develop, any stem cell-based therapies that come out of them will have to go through more testing in larger mammals before doctors can even begin...
...about this point, a UCLA student in the libary switched on a video-recording cell phone. The first sounds that fill the clip, those of a frightened Tabatabainejad repeatedly screaming, “Don’t touch me,” make it clear that the next six minutes will broadcast distressing images. But it is actually Tabatabainejad’s tortured wailing during video’s “Tases” that is truly disturbing...
...fish five or more times a week had a 40% lower risk of developing colorectal cancer than men who ate it less than once a week. I've long believed that the omega-3 fatty acids in oily fish inhibit the COX-2 enzyme that increases both inflammation and cell proliferation...
CELLULAR CABIN As early as January, Dubai-based Emirates will become the first airline to let passengers use cell phones during flight, provided they're set to vibrate. And please, no loud yapping with on-ground friends during the in-flight film...
