  1. Why a broken heart really does hurt

    "The findings back the common theory that rejection 'hurts' by showing that a gene regulating the body's most potent painkillers – mu-opioids – is involved in socially painful experiences too.

    Their study indicates that a variation in the mu-opioid receptor gene (OPRM1), often associated with physical pain, is related to how much social pain a person feels in response to social rejection.

    People with a rare form of the gene are more sensitive to rejection and experience more brain evidence of distress in response to rejection than those with the more common form."

  2. Wi-Fi via White Spaces

    "TV stations have traditionally broadcast over lower frequencies that carry information longer distances. However, with the ongoing transition from analog to digital broadcasts, more unused frequencies are opening up than ever.

    By tapping into these lower frequencies, it should be easier to provide broadband Internet access in rural areas and fill in gaps in city Wi-Fi networks. For example, the spectrum between 512 megahertz and 698 megahertz, which was originally allotted to analog TV channels from 21 to 51, offers a longer range than conventional Wi-Fi, which operates at 2.4 gigahertz. "Imagine the potential if you could connect to your home [Internet] router from up to a mile," says Ranveer Chandra, a member of the Networking Research Group at Microsoft Research behind the project." Yeah, like they're just gonna open up all that taxable/licensable bandwidth for free. Dream on.
