A French architect campaigning for a new exploration of the 4,500-year-old Great Pyramid of Giza said on Thursday that the edifice may contain two chambers housing funereal furniture. A 3-D simulation of the structure suggests an ancient secret lies beneath the desert sand.

The rooms would have housed furniture for use in the afterlife by the pharaoh Khufu, also known as Cheops in Greek, he told a press conference. “I am convinced there are antechambers in this pyramid. What I want is to find them,” he said.

Sitting at home on a lonely Saturday night often means an evening of catching up on Facebook stalking, but, according to Stanford researchers, all that lurking can deepen depressed feelings.

Facebook offers only a glimpse into a person’s life, and that abbreviated version usually includes an unbalanced amount of newsfeed-worthy highlights and skips over the mundane or unhappy. Showcasing only bits and pieces can make others feel like their life is boring and lonely compared to that of their constantly status and photo-updating friends.

Researchers found that people underestimate their friends’ loneliness or sadness and overestimate pals’ partying and fun.

Internet, mobile phones cut as Egypt braces for protests

Media_httpuploadwikim_ewxiv

Egypt cut mobile phone and Internet services on Friday and sent columns of riot police trucks into Cairo in a bid to thwart thousands of activists due to join anti-regime protests after noon prayers.

Egyptian police have struggled to deal with protesters, who for the past three days have clashed heavily with police in Cairo and other cities as they demand the ouster of veteran President Hosni Mubarak. Cell phone text messaging was cut late Thursday while Internet services, which had been patchy during the night, were completely severed early Friday, cutting off access to networking sites Facebook and Twitter — key communications’ tools used by organizers of the protests.

Media_httpuploadwikim_pcxff

E-cigarettes may offer a relatively safe way to help smokers quit, but the health effects are still unknown. The devices, which are tobacco-free, may be a safer alternative to cigarettes, say advocates.

  • Tree dwellers experience more stress on the pinky side of their hands while terrestrial species tend to load more stress on the thumb side.
  • The timing of the switch coincides with climate and habitat changes and a shift in diet.
