MTorrice writes "A new study suggests there's more to nanoparticle toxicology than cell life and death. Although immune cells treated with iron oxide particles appeared healthy in standard toxicology tests, they struggled to perform one of their key jobs: engulfing pathogenic bacteria. The researchers wonder if exposure to significant levels of the nanoparticles could lead to dysfunction in people's immune systems."

New submitter coyote_oww writes "ComputerWorld analysis article suggests that Microsoft should stop worrying about one product cutting into another product's sales, and concentrate on putting their best foot foward regardless of the impact on product lines. The big impact would be the price of Windows: '... Microsoft must, at least in the main, sell devices based on lower prices. And the only significant component of a Windows-powered device that can be cut further — hardware margins are at or very near the bone, and have been for years — is the Windows license.' It's still possible they could sell Windows versions at different rates for different devices, but that could get hard to justify to consumers over the long haul."

New submitter SkiTee94 writes "Many people, perhaps millions, in and around NYC were loudly awoken shortly before 4am morning by an activation of the Wireless Emergency Alert system. As the New York Times is reporting, the alert was related to an ongoing search for a missing child. Given that the alert asked people to look out for a 'Tan Lexus ES300' with NY Plate 'GEX1377,' many New Yorkers are questioning the logic of waking up the whole city to ask them to look for a car. Normally such alerts are reserved for road-side signs. While emergency authorities have yet to give a precise reason for why the decision was made to wake up the city, many have taken the step of deactivating these alerts to avoid future jolting mid-slumber alarms (likely not the indented result of last night's exercise)."

sciencehabit writes "When surgeons can't determine the edges of a tumor, it's a problem. Cut too much, and they risk hurting the patient. Cut too little, and they may leave stray cancer cells behind. Now, researchers have developed a surgical knife that can sniff the smoke made as it cuts tissue, almost instantly detecting whether cells are cancerous or healthy. The 'intelligent knife,' or iKnife could distinguish normal and tumor tissues from different organs, such as breast, liver, and brain, and could even identify the origin of a tumor that was a metastasis, a secondary growth seeded by a primary tumor elsewhere in the body."
