Frosty Piss writes: Lazar Greenfield, M.D. is no ordinary surgeon. Until last week, he was the president-elect of the American College of Surgeons, and was also the lead editor of the Surgery News. In the February issue, he penned some thoughts on Valentine's Day under the heading of "Gut Feelings." Greenfield proceeded to then discuss the mating habits of fruit flies, the mating habits of the rotifer. In each case, Dr. Greenfield made sure to reference to the scientific literature. Then he turned his attention to humans. Dr. Greenfield noted the therapeutic effects of semen, citing research from the Archives of Sexual Behavior which found that female college students practicing unprotected sex were less likely to suffer from depression than those whose partners used condoms (as well as those who remained abstinent). His comments apparently didn't sit well in certain quarters. Dr. Greenfield was forced to resigne as editor of the Surgery News and gave up his stewardship of ACS after learning that his article had spurred threats of protests from outside women's groups.
BSDer writes: An Israeli security researcher published a paper few hours ago, detailing attacks against Mac, OpenBSD and other BSD-style operating systems. The attacks, says Amit Klein from Trusteer enable DNS cache poisoning, IP level traffic analysis, host detection, O/S fingerprinting and in some cases even TCP blind data injection.
The irony is that OpenBSD boasted their protection mechanism against those exact attacks when a similar attack against the BIND DNS server was disclosed by the same researcher mid 2007. It seems now that OpenBSD may need to revisit their code and their statements.
According to the researcher, another affected party, Apple, refused to commit to any fix timelines. It would be interesting to see their reaction now that this paper is public.
CaffeineFree writes: Ars Technica did an interview with Evan Malone of Fab@Home, the open-source project that provides drivers, applications software, and detailed design plans for assembling a three-dimensional desktop fabricator. In it, he discusses the project and what it means for home fabrication enthusiasts. From the article:
Malone's machine puts fabbing within hobbyist budgets for the first time. Since the first Model 1 Fabber began life in the summer of 2006, Malone has launched a wiki and built a community of enthusiastic tinkerers, all in his spare time.
The project has already attracted worldwide attention; Malone has taken his device to South Africa at the request of the government there, and one of the first Model 1 machines has already been requested for an exhibit at the Science Museum in London. Early machines are still primitive, but they work reliably. A Model 2 revision is already in the works.
Fab@Home is about more than making small plastic objects in your living room, however. Malone and his mentor, Dr. Hod Lipson, believe that such devices can change the world.
QuantumCrypto writes: "Researchers at Rensselaer Polytechnic Institute have created "the world's first material that reflects virtually no light." This anti-reflection technology is based on nanomaterial and could lead to the development of more efficient solar cells, brighter LEDs, and "smarter" light sources... In theory, if a room were to be coated with this material, switching on the lights would only illuminate the items in the room and not the walls, giving a sense of free-float in infinite space. How cool is that!"
