It’s inevitable that any discussion about hydrogen-power cars takes a turn towards the ”... and just where are we going to get all that hydrogen from?” angle in about 30 seconds.. Researchers in Israel may have taken us one step closer to answering that question. They’ve developed a process where zinc ore is heated in the presence of charcoal via solar energy and smelted into elemental zinc powder. That powder can then be reacted with water to form hydrogen and zinc oxide, which is returned back to the start of the process. The powder can also be stored for future use, or used to create electricity just like a zinc-air hearing-aid battery.
And from Medpundit:
From the Land of the Ever Young:: Is the placenta going to turn out to be the salvation of mankind? (An argument could be made that it already is, since none of us would be here without it):
Scientists looking for easier and less-controversial alternatives to stem cells from human embryos said on Friday they found a potential source in placentas saved during childbirth.
They described primitive cells found in a part of the placenta called the amnion, which they coaxed into forming a variety of cell types and which look very similar to sought-after embryonic stem cells.
In addition to being researchers at the University of Pittsburgh, the researchers are also shareholders in a company called Stemnion, a biotechnology company that runs the business side of their research. Nothing wrong with that, except that it puts added pressure on them to succeed - or at least give the appearance of succeeding.
