Should Network Cables Be Replaced? 524

Jyms writes "As technology changes, so hubs routers and switches are upgraded, but does the cabling need replacing, and if so, how often? Coax gave way to CAT 5 and CAT 5e replaced that. If you are running a 100Mbit/s network on old CAT 5, can that affect performance? Do CAT 5(e) cables get old?"

The Taste Of Space Screenshot-sm 81

It turns out that space tastes like raspberries and not Tang or freeze-dried ice cream as one might suspect. Scientists at the Max Planck Institute for Radio Astronomy were searching for evidence of amino acids in space when they found ethyl formate, the chemical used in to make raspberry flavoring. The astronomers used the IRAM telescope in Spain to analyze electromagnetic radiation emitted by a hot and dense region of Sagittarius B2 that surrounds a newborn star. Astronomer Arnaud Belloche said, "It [ethyl formate] does happen to give raspberries their flavour, but there are many other molecules that are needed to make space raspberries."

Researchers One Step Closer To Creating Life 292

An anonymous reader writes "Researchers at the Scripps Research Institute are potentially one step closer to creating life. In an experiment they recently created enzymes that can replicate and evolve. 'It kind of blew me away,' said team member Tracey Lincoln of the Scripps Research Institute, who is working on her Ph.D. 'What we have is non-living, but we've been able to show that it has some life-like properties, and that was extremely interesting.'"

Tech Companies That Won't Survive 2009 385

buzzardsbay writes "Fresh off their annual market survey, eWEEK channel folks have compiled the list of tech vendors their readers think will fail, falter, or be sold off in 2009. It's important to note that these aren't the opinions of the magazine or its editors. The list comes from folks who work in IT, mostly technology resellers, who are out in the field selling, installing and maintaining this stuff. If there were ever canaries in the tech coal mine, they'd be these service and solution providers who live and die by the slightest shift in the markets. Some of the companies on this list, like Sun and AMD, are shocking because of their size. Others, like CA and Symantec, not so surprising." What other companies are headed for implosion, or should be if all were right with the universe?

Implant Raises Cellular Army To Attack Cancer 193

holy_calamity writes "New Scientist reports on a sneaky new approach to getting the immune system to fight cancer. An implant releases a 'molecular perfume' irresistible to messenger immune cells, which enter the implant where they are given a sample of the cancer's 'scent' and a disperse signal that sends them scurrying to the nearest lymph node. There they convince other immune cells to start attacking anything that matches the sample they picked up."

Class Teaches Nerds Social Skills Screenshot-sm 639

PeterAitch writes "According to Reuters, Potsdam University in Germany is now teaching social skills as part of their IT courses. This is intended to 'ease entry into the world of work'. The 440 students enrolled in the master's degree course will learn how to write flirtatious text messages and emails, impress people at parties and cope with rejection(s)." The class is taught by a superficial model, who will fall in love with the nerdiest student at the end of the semester after realizing that he is beautiful on the inside.
