Higher Power Could be Easier to Manage for Nuclear Fusion Tokomaks and Stellarators

A discovery made in the RFX-mod Reversed Field Pinch (RFP) fusion device demonstrated that if one keeps on increasing the current, above 1.5 million amperes, the helix becomes very smooth, the trapping of the plasma in the magnetic fields improves and the plasma gets hotter. Moreover, the helical state appears to be the preferred one …

Rice pioneers method for processing carbon nanotubes in bulk fluids

Rice University scientists today unveiled a method for the industrial-scale processing of pure carbon-nanotube fibers that could lead to revolutionary advances in materials science, power distribution and nanoelectronics. The result of a nine-year program, the method builds upon tried-and-true processes that chemical firms have used for decades to produce plastics. The research is available online …

Simpler Generation of Attosecond Pulses

Attosecond physics is a burgeoning field in which researchers use ultrashort optical pulses to excite atoms and molecules and follow the electron dynamics. Driving atoms with longer-duration pulse sequences can generate trains of attosecond pulses, but what workers in this field really need are isolated attosecond pulses. However, the technologies for slicing out single pulses …

Improved Understanding of Why Stem Cells Stop Dividing

These blue cells are human mesenchymal stem cells that have become senescent –- or lost the ability to divide — after X-ray irradiation. This image, obtained using senescence-associated β-gal staining, helped Berkeley Lab scientists better understand the process that triggers senescence in mesenchymal stem cells. Scientists from the U.S. Department of Energy’s Lawrence Berkeley National …
