Comment: Living in space means living in caves (Score 5, Interesting) 80

Very large caves...cavernous spaces. The radiation from Solar flares, Cosmic Rays, etc. means humans need a lot of shielding and that really only comes from a lot of mass between you and the vacuum. If we live on mars, moon or somewhere else, it will have to mean living underground. Earth has a magnetic field and an atmosphere that traps, deflects and degrades most high energy particles (==radiation) before they get to the ground. Other problems solved by caverns include: The moon and Mars change temperature 100C or more between day and night. Micrometeors that make a nice glow as trails at night on Earth act as a 30,000 kph BB gun on the moon. Living outside is very bad for your health.

I really want to see what a 100 meter wide, kilometer long cavern looks like from inside. The roof is 100 meters or more thick and has survived for billions of years. It should not be too hard to seal and pressurize it. The first images from a camera lowered into such a huge cavern, with the right lighting. will be stunning and will change the way we view living in space.

Corporations Hiring Hooky Hunters 610

No longer satisfied with your crinkled doctor's note, a growing number of corporations are hiring "Hooky Detectives." Private investigator Rick Raymond says he's staked out bowling alleys, pro football games, weddings and even funerals looking for people using sick days. From the article: "Such techniques have become permissible at a time when workers are more likely to play hooky. Kronos, a workforce productivity firm in Chelmsford, Mass., recently found that 57 percent of salaried employees take sick days when they're not sick — almost a 20 percent increase from statistics gathered between 2006 and 2008."

One Night Stands May Be Genetic 240

An anonymous reader writes "So, he or she has cheated on you for the umpteenth time and their only excuse is: 'I just can't help it.' According to researchers at Binghamton University, they may be right. The propensity for infidelity could very well be in their DNA. In a first of its kind study, a team of investigators led by Justin Garcia, a SUNY Doctoral Diversity Fellow in the laboratory of evolutionary anthropology and health at Binghamton University, State University of New York, has taken a broad look at sexual behavior, matching choices with genes and has come up with a new theory on what makes humans 'tick' when it comes to sexual activity. The biggest culprit seems to be the dopamine receptor D4 polymorphism, or DRD4 gene. Already linked to sensation-seeking behavior such as alcohol use and gambling, DRD4 is known to influence the brain's chemistry and subsequently, an individual's behavior."

mernilio writes "According to UPI: 'A Massachusetts school district superintendent said a memo banning sixth graders from carrying pencils was written without district approval. North Brookfield School District interim Superintendent Gordon Noseworthy said Wendy Scott, one of two sixth-grade teachers at North Brookfield Elementary School, did not get approval from administrators before sending the memo to all sixth-grade parents, the Worcester Telegram & Gazette reported Thursday. The memo said students would no longer be allowed to bring writing implements to school. It said pencils would be provided for students in class and any students caught with pencils or pens after Nov. 15 would face disciplinary action for having materials 'to build weapons.'"

Ontario School Bans Wi-Fi 287

St. Vincent Euphrasia elementary school in Meaford, Ont. is the latest Canadian school to decide to save its students from the harmful effects of Wi-Fi by banning it. Schools from universities on down have a history of banning Wi-Fi in Ontario. As usual, health officials and know-it-all scientists have called the move ridiculous. Health Canada has released a statement saying, "Wi-Fi is the second most prevalent form of wireless technology next to cell phones. It is widely used across Canada in schools, offices, coffee shops, personal dwellings, as well as countless other locations. Health Canada continues to reassure Canadians that the radiofrequency energy emitted from Wi-Fi equipment is extremely low and is not associated with any health problems."

One small step for man, one giant stumble for mankind.
