Experiments In Outer Space To Determine single Cell Survival

...could result in cell death. Thus, the yeast can be modified to glow fluoresecent green when they contact a harmful chemical or biotoxin. Because such nanostructures are cheap, extremely light and small, and easy to make, they could conceivably be attached to insects and their emanations read remotely by bea...

Gene Responsible For Mammary Gland Function, When Mutated Results in Leukemias

...dy the role of MKL1, the team produced genetically modified mouse embryos that lacked the MKL1 gene (MKL1 -/- mice) and observed what happened in the mice when the gene was absent. The investigators reported that about 40 percent of mouse embryos that lacked MKL1 did not survive to birth, although the mice th...

DNA-bound p53 Tumor Suppressor Protein Structure Determined

...nding to DNA. We used a chemical trick in which we modified a DNA base to allow it to attach directly to a part of the protein's core domain. That allowed us to trap the form of the p53 dimer that’s compatible with DNA binding. And we solved the structure. We saw what it looked like." (Source: Newswis)...

Mice with the hyperactive NFATc in their osteoblasts had an immense increase in bone mass compared to normal mice, suggesting that the balance between bon...

HFEA Issues Warning On Risks Of Multiple Births With IVF
