Security management vendor NetIQ last week unveiled Change Administrator, which provides change control for network servers. The software lets users delegate permissions for individual administrators based on the tasks they need to perform instead of granting them full access to a server. The software can report on who is accessing specific servers and at what time, information that can be key for compliance auditing. Pricing starts at $2,000 per server.

Researchers at the Massachusetts Institute of Technology have found a way to extend the power life of mobile computers. Instead of from batteries, they draw power from an electronic device called an ultracapacitor, which works through nanotechnology. Ultracapacitors are still several years away from being used as the main electricity source for commercial laptops and handhelds, but are already used for back-up power in many small consumer products.
