Study finds that caching by browsers creates a threat to surfers' privacy

Article Abstract:

Dr. Edward W. Felten and Michael Schneider have discovered a way for Web sites to gather data using a Web browser's cache. The cache saves bits of Web pages to a user's PC hard drive, for faster loading of the pages. In the researcher's test, a consumer opened the home page of an online store. This triggered their Java applet, which in turn, opened a microscopically-sized page of a competitors home page. If the page loads quickly, chances are good the consumer has spent time on the competing site. This program could be run to monitor other kinds of browsing activity and is not blocked by anonymous surfing services. Web browser software makers say what is at issue is a trade off between complete security and having a speedy and smooth Web experience.

Quantum computers: using light instead of moving atoms

Article Abstract:

Pierre M. Petroff, Atac Imamoglu and Evelyn L. Hu presented a paper on the research they have done on the possibility of the development of a tiny, photon-emitting semiconductor that would power a 'quantum computer.' Photons, or basic light particles, would operate the computers rather than the movement of atoms. The semiconductor, based on a structure created by Petroff, is formally known as 'a quantum dot single-photon turnstile device.'

Inside the virtual laboratory, ideas percolate faster than rivalries

Article Abstract:

More and more scientists are finding that Web-based services are ideal for sharing information and gaining insights into the research of others. There are great advantages in having serveral different researchers collaborating simultaneously which can yield dramatic breakthroughs. The greatest obstacles to this trend is long-held traditions within the scientific research community and concerns over protecting intellectual property.
