U.S. House OKs small business health plan
The U.S. House of Representatives on Tuesday approved legislation that would allow small businesses to pool together to purchase health insurance for their workers.
Backers said the measure would restrain health costs and help cover some of the millions of uninsured working people, but critics said this approach could provide bare-bones insurance to some workers and leave others facing even higher bills.
Gene engineered stem cells heal rat spines -study
Genetically engineered stem cells can help rats’ severed spinal cords grow back together, according to a study published on Tuesday.
Rats given the treatment, using stem cells taken from rat embryos, could move their legs again after their spines were severed in the lab, said the researchers’ report in the Journal of Neuroscience.
The scientists hope the approach, which generated a new fatty cover for the spinal cord cells called the myelin sheath, also could be shown to work in people.
