Two Warnings on Diet Pills

    The Food and Drug Administration is warning people to stay away from dozens of diet drugs sold over the Internet that may contain undisclosed and possibly dangerous ingredients, including a carcinogen, The Chicago Tribune reports.

    Nostalgia Gets a Closer Look

    Think nostalgia is for wimps?

    Inner Conflict at the Mall

    Shopping is war -- war between the brain's pleasure center and its aversion center, which seeks to avoid the pain of paying, The Boston Globe says. M.R.I. scans show that when people are shopping, the nucleus accumbens, a seat of pleasure in the brain, lights up, as does the insula, a pain center.

    An Aria for the Ill

    Live music is played in some hospitals to create a comforting environment for chronically or terminally ill patients, The Washington Post reports. Unlike music therapy, which uses music to help people reach certain goals in treatment, this therapeutic approach seeks only to provide solace.

    你認為沒用的人才會懷念往事？據(jù)洛杉磯時報報導，一些心理學家說留戀的回憶是有好處的，它能幫助人們在孤獨的時候振作起來和度過難關。研究人員甚至在開展驗證留戀舊事能否用來幫助失去愛人的人的實驗。

    購物中心內部的戰(zhàn)爭

    據(jù)波士頓國際報報導，購物是一場戰(zhàn)斗—一場大腦的愉悅中心和希望逃避付款的痛苦的反感中心的戰(zhàn)斗。核磁共振成像的掃描結果表明，人們在購物時，大腦中控制愉悅的所在地伏隔核和痛苦中心腦島都會興奮起來。

    病人的詠嘆調
