Bee screened
embryos with nuclei from human cells inserted into the eggs of either cows, pigs, sheep or other animals. When the issue was debated in Parliament, many leading scientists strongly supported such research. “Animal–human hybrid embryo research needs legal permission, good scientists and more funding,” says Evan Harris, the science spokesman for the Liberal Democrat Party. Many of those involved ...
متن کاملScreened Casimir forces
We demonstrate that a very recently obtained formula for the force on a slab in a material planar cavity based on the calculation of the vacuum Lorentz force [C. Raabe and D.-G. Welsch, Phys. Rev. A, 71, 013814 (2005)] describes a (medium) screened Casimir force and, in addition to it, a medium-assisted force. The latter force also describes the force on the cavity medium. For dilute media, it ...
متن کاملScreened Perturbation Theory
A new perturbative scheme is proposed for the evaluation of the free energy density of field theories at finite temperature. The screened loop expansion takes into account exactly the phenomenon of screening in thermal propagators. The approach is tested in the N -component scalar field theory at 2-loop level and also at 3-loop in the large N limit. The perturbative series generated by the scre...
متن کاملSelf-Screened Parton Cascades
The high density of scattered partons predicted in nuclear collisions at very high energy makes color screening effects significant. We explain how these screening mechanisms may suppress nonperturbative, soft QCD processes, permitting a consistent calculation of quark-gluon plasma formation within the framework of perturbative QCD. We present results of a model calculation of these effects inc...
متن کاملScreened DNA packs faster.
Despite being negatively charged, DNA can be compacted to almost crystalline densities inside virus capsids. However, how this is achieved has been debated for years. Most theoretical models predict that attractive DNA–DNA interactions — such as those resulting from the screening effect of nearby positively charged molecules — would facilitate DNA packaging by countering the effects of DNA self...
