by taking a single human breast tissue sample, splitting it in two and growing the cells in the two culture mediums, which select for different cells. Next, he transformed the two populations with the same tumor-initiating genes, injected them in mic...

between them. The protein that drops off has two arms: One arm attaches to the protein fibers forming the skeleton, and the other anchors itself to the cell membrane. This action is what stabilizes the cells structure. The protein that increases, on ...

between a harmless king snake and a venomous coral snake! Richard Louv notes in his book that children growing up over the last 20 years have increasingly limited experience of the outdoors, which is contributing to decreased understanding and appr...
Where broken DNA is repaired

between the 17-OHPC and placebo groups. Birth or miscarriage before 35 weeks gestation occurred in 41.5 percent of the 17-OHPC group and in 37.3 percent of the placebo group. The researchers concluded that treatment with 17-OHPC did not reduce the ...
