Hold the phone - away from you? A new study confirms cell phones increase activity in the brain cells nearest to the phone. But no one knows for sure if all that brain activity is healthy - or lethal.
We're picking at your brain with coverage from Fox News, NBC, Discovery News, and The Washington Post.
Check out how the study worked. 47 people, each with a cell phone strapped to each side of their head for 50 minutes. One was off - the other was muted. The results? A seven percent increase in activity in the brain cells closest to the muted phone. (Video Source: NBC)
A doctor tells Fox News even though no link was found between cell phone use and disease, increased brain activity from cell phones isn't healthy.
"Like anything else, any kind of motor, if you think about how diseases get, you know, get produced, is by the cells, you know, overutilizing energy, multiplying rapidly."
But some scientists are skeptical of long-term damage. A doctor and a scientist share their thoughts on NBC's Nightly News.
MICHAEL WEINER: "There's nothing in this paper that suggests that cell phones have any adverse effect or harmful effect on the brain."
ROBERT BAZELL: "Most physicists who study radiation have always said that cell phones could not cause brain tumors or other health problems."
ROBERT CAHN: "The cell phone doesn't emit enough power to be damaging the human body."
A bioengineer tells Discovery News there are too many variables to accurately measure the brain's activity.
"[C]ell phones emit more radiation when a person is talking ... Radiation levels also change depending on the phone type, the distance to the nearest cell phone tower and the number of people using phones in the same area."
Finally, an opinion writer for the Washington Post takes a satirical jab at the study, saying texting is the way to go.
"Since getting a cell phone, at least 7 percent of my brain has continually been active wondering whether anyone has sent me a text message...Without my cell phone, I am lost. With it, I am also lost, but I can text somebody."
The authors of the study say more research is still needed.

拿着手机 - 远离你？最近的一项新的研究证实到手机手机在脑细胞的活性增加。但是，没有人知道所有的大脑活动是健康的肯定 - 或致死。
我们为您挑选与福克斯新闻，美国全国广播公司，发现新闻，华盛顿邮报报道大脑。
看看如何研究工作。 47人，与他们绑在每头50分钟每方一个手机。一个是关闭 - 另一个是静音。结果呢？阿的活动增加百分之七，脑细胞最接近静音手机。 （视频来源：美国全国广播公司）
一位医生告诉福克斯新闻，即使没有连接之间使用手机和疾病增加，从手机的大脑活动，发现不正常。
“其他任何事情一样，任何一种运动，如果你想想疾病如何得到的，你知道，取得生产，由细胞，你知道，overutilizing能源，乘迅速。”
但是，一些科学家是长期的损害表示怀疑。一个医生和科学家共享NBC的晚间新闻上的想法。
迈克尔韦纳：“没有什么，本文这表明，手机有任何不利影响或对大脑有害的影响。”
罗伯特BAZELL：“大多数物理学家谁研究辐射一直说，手机不能导致脑肿瘤或其他健康问题。”
罗伯特卡恩：“手机不会产生足够的力量对人体造成损害。”
一名生物工程学家告诉探索新闻有太多的变量，精确测量大脑的活动。
“[中]埃尔电话放出更多的辐射当一个人说话...辐射水平也改变手机类型的不同，到最近的手机塔和在同一地区使用手机的人数距离。”
最后，华盛顿邮报认为作家需要在研究讽刺申诉，说短信是一段路要走。
“自从获得一部手机，至少有7我的大脑中有百分之不断积极想知道是否有人给我发了短信我的手机...不，我失去了。有了它，我也输了，但我可以文字的人。“
这项研究的作者说，还需要更多的研究。
