...board of directors of the Harvard Management Company, the University’s endowment management arm. Berman joins several other Harvard professors and administrators who serve on corporate boards. Lawrence University Professor Michael E. Porter, for example, holds numerous corporate board positions, such as Parametric Technology Corporation, Thermo Electron Corporation, and Inforte Corporation. Berman is scheduled to depart from her post in April after over a decade of service for the University in order to pursue an interest in foreign languages in Italy. She will then return to Cambridge in an as-of-yet unspecified advisory role for the University...
...Randall was dealing with another problem before she considered the hierarchy problem: examining supersymmetry, a theory that claims every fundamental particle has a partner (like an electron with a negative charge and a positron with an equivalent positive charge...
...Randall hopes that the Large Hadron Collider, a giant particle accelerator near Geneva, Switzerland will test her theories. Colliding proton beams at a combined energy of 14 trillion electron volts, it will start operation in 2007. The collider could produce particles such as the sought-after graviton believed to convey the gravitational force, or it could produce actual strings...
...heart. Calcium can then build up in the vessels and stiffen them, laying the foundation for heart disease. Getting one's calcium score is as simple as getting a quick injection of a contrast agent in the arm and a zap from an ultrafast X ray, either by electron beam computed tomography (EBCT) or by multidetector CT. Studies show that in every age group people with higher calcium levels have a greater risk of heart attack than do people of the same age with lower scores...
...most opinionated harrumphs, and this year the SED flat-panel technology developed by Toshiba and Canon was at the center of scrutiny. Billed as the technology that could bring down plasma, SED takes the idea of conventional cathode-ray-tube televisions and miniaturizes it: instead of one big electron gun exciting all the phosphors on a screen in sequence, millions of little electrical nodes do the same thing simultaneously. The result is picture contrast and response time that outstrip plasma and LCD with a much lower power drain. Toshiba says that production costs over time could make SED TVs relatively...
