The billion-pixel Mars is a click away at the NASA homepage, the zoom feature makes it safe to load and view
Regenerative medicine is coming and when it does it could transform medical care more dramatically than the development of antibiotics to treat infections and blood transfusions to save trauma patients combined. Here’s how it might work:
IN PRINCIPLE, THE PROCESS of treating diseases with stem cells made with a patient’s DNA will work something like this: 1) take easily available cells (like skin cells) from a patient with, say, Parkinson’s Disease, 2) transform the skin cells into stem cells, and then 3) coax those stem cells to become dopamine-secreting cells, which you can transplant back into the patient. If you’re really ambitious, you can edit the DNA of those cells to repair the Parkinson’s-causing mutation before transplanting them back into the patient. A second approach is to 1) take isolated DNA from a patient, 2) transplant that DNA into a donated human egg cell, 3) induce that egg cell to become an embryo and extract the stem cells, then 4) use those stem cells to create specialized cells that get transplanted back into the patient.
We would probably need to tweak existing laws for something like that to become a reality. Fear of the sci-fi clones could hamper some research. But most importantly, to get adult stem cells to do what embryonic stem cells do, we first have to understand at the very least precisely how embryonic stem cells work. Which involves … studying embryonic stem cells in great detail. Duh.
Happy Summer, godless pagan lefties! If you happen to be out dancing wildly—at Netroots Nation or casting spells in the woods—under the night sky this weekend, be sure and look up and enjoy the supermoon.
I need to pick the brain of a research scientists or two on the grant process. See me in comments below. Or you can comment and/or find my email on this site, where you can also see Hubble’s close encounter of the galactic kind.
“Ever since we caught sight of the Earth among the rings of Saturn in September 2006 in a mosaic that has become one of Cassini’s most beloved images, I have wanted to do it all over again, only better,” said Carolyn Porco … “This time, I wanted to turn the entire event into an opportunity for everyone around the globe …”
