SeaDour writes "The famous Deep Impact mission, which in 2005 launched a projectile in the path of comet Tempel 1, may be extended by NASA. The proposal is to slingshot the probe around the Earth as it passes by at the end of this year, putting it on a trajectory to reach comet Boethin in December 2008. Scientists want to see if the strange composition and behavior of Tempel 1 is more common than they had previously assumed. (The probe only had one projectile though, so we will not see another brilliant man-made explosion on this comet.) Additionally, while the probe is en route to the comet, researchers will point its on-board telescope at known exosolar planets to determine the compositions of their atmospheres."

Alreadybutnotyet writes "A French architect claimed Friday to have uncovered the mystery about how Egypt's Great Pyramid of Khufu was built — with use of a spiral ramp to hoist huge stone blocks into place. The construction of the Great Pyramid 4,500 years ago by Khufu, a ruler also known as Cheops, has long befuddled scientists as to how its 3 million stone blocks weighing 2.5 tons each were lifted into place. 'The most widespread theory had been that an outer ramp had been used by the Egyptians, who left few traces to help archeologists and other scientists decode the secret to the construction. Houdin said he had taken into account the copper and stone tools available at the time, the granite and limestone blocks, the location of the pyramid and the strength and knowledge of the workers.'"

An anonymous reader writes "If you own a mom & pop store and can't get rid of some of your inventory, you can always clear out some shelf space by holding a sale. If the Supreme Court sides with business interests in a case they heard today, however, such sales may no longer be possible. Since 1911 it has been illegal for manufacturers to force retailers into setting a price floor for products — individual retailers get to decide how much they sell products for. But today the Supreme Court heard oral arguments in a case seeking to overturn this longstanding rule. Should the Court do so, it would drive up consumer prices across the board. This case is particularly salient in the era of Internet shopping: consumers are now easily able to shop around to multiple retailers to find the best price. The Court could wipe out this advantage." From the article: "Should the Court abandon the... rule against minimum resale price maintenance... it would send a signal that the Roberts Court will continue to narrow the application of the antitrust laws and that the Court may disregard settled precedent and Congressional will in other areas of the law as well."

db32 writes "SFGate has the story of the cutoff date for those rabbit ear antennas that some of us grew up with (Feb. 19, 2009). Now while the story of analog vs. digital TV has been beaten to death, still I think there is something more here. 'The Department of Commerce's National Telecommunications and Information Administration... said it is setting aside $990 million to pay for the boxes. Each home can request up to two $40 coupons for a digital-to-analog converter box, which consumer electronics makers such as RCA and LG plan to produce.' Beyond my disdain for most TV to begin with, I am blown away that with all of our current problems — homelessness and crime on the home front, war fighting and terrorism abroad — our government is seriously going to spend this much money on upgrading peoples' televisions."

odie_q writes "It has long been known that the Toxoplasma gondii parasite alters its host's behavior, but now it seems the way it alters it depends on the sex of the host. From the article: 'A common parasite can increase a women's attractiveness to the opposite sex but also make men more stupid, an Australian researcher says ... Infected men have lower IQs, achieve a lower level of education and have shorter attention spans. They are also more likely to break rules and take risks, be more independent, more anti-social, suspicious, jealous and morose, and are deemed less attractive to women. On the other hand, infected women tend to be more outgoing, friendly, more promiscuous, and are considered more attractive to men compared with non-infected controls.'"

duguk writes in with another reason to keep happy over Christmas. A new scientific study suggests that people who frequently experience positive emotions are less likely to catch colds. Psychologist Sheldon Cohen and his colleagues at Carnegie Mellon University interviewed 193 healthy adults daily for two weeks and recorded the positive and negative emotions they had experienced each day. The researchers then exposed the volunteers to a cold or a flu virus. Those with "generally positive outlooks" reported fewer cold symptoms. From the article: "'We need to take more seriously the possibility that a positive emotional style is a major player in disease risk,' Cohen says... Although a positive emotional style bore no relation to whether participants became infected, it protected against the emergence of cold symptoms. For instance, among people infected by the influenza virus... 28 percent who often reported positive emotions developed coughs, congestion, and other cold symptoms, as compared with... 41 percent who rarely reported positive emotions."

Kotaku reports the news that problems with breaking Wiimote straps has resulted in a class action lawsuit against Nintendo. From the press release about the suit: "Green Welling LLP filed a nationwide class action lawsuit on behalf of the owners of the Nintendo Wii against Nintendo of America, Inc., in the U.S. District Court for the Western District of Washington. The class action lawsuit arose as result of the defective nature of the Nintendo Wii. In particular, the Nintendo Wii game console includes a remote and a wrist strap for the remote. Owners of the Nintendo Wii reported that when they used the Nintendo remote and wrist strap, as instructed by the material that accompanied the Wii console, the wrist strap broke and caused the remote to leave the user's hand. Nintendo's failure to include a remote that is free from defects is in breach of Nintendo's own product warranty."

IAmTheDave writes "A California anti-pretexting bill that got unanimous support in the state senate with a vote of 30-0 was struck down after heavy last-minute lobbying by the MPAA. The bill aimed to make deceptive 'pretexting' (lying) to gain personal information on another person illegal. The MPAA told legislators 'We need to pose as someone other than who we are to stop illegal downloading,' and thus killed the bill when it came up for a final vote. California passed a much narrower bill that 'bans the use of deceit to obtain telephone calling records, and nothing else.' In a final 'think of the children' bid, the Califonia Association of Licensed Investigators also opposed the bill, saying it needed to be able to use pretexting to help find missing children, among other things."
