Well, by the looks of it, he is trying to kill off whatever residual brain cells he has. That's a sure-fire trip to the emergency room!

BY BRANDON TWICHELL You're watching multisource health news analysis from Newsy 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.

BY STEVEN SPARKMAN ANCHOR: CHRISTINA HARTMAN You're watching multisource science news analysis from Newsy. If you’re running low on sleep, your brain might be napping without you. New research suggests individual brain cells can go to sleep, even while you seem wide awake. Australia’s ABC Online has more. “Professor Tononi's team kept rats awake for four hours beyond their normal bedtime and recorded the activity of some individual neurones as they became more and more sleep deprived. Outwardly the rats appeared to be completely awake, but the brain cell recordings told a different story.” The recordings showed small sections of the brain slipping into sleep mode. The longer the rats were kept awake, the more cells went offline. Discover Magazine explains this is only one trick animals use to rest their brains, and it has some drawbacks. “Whales, dolphins and several birds can send each half of their brain to sleep in shifts, so that they can stay continuously awake. ... A dolphin can stay this way for five straight days without any loss of mental agility. Rats, and indeed humans, cannot. We suffer from lapses in attention, irritability and poor judgment, often without realising it.” In this study, the researchers measured those lapses in attention by making the rats perform tricky grabs at hard-to-reach sugar pellets. The sleep deprived ones had more trouble with the task. A neuroscientist told NPR that although this is an animal study, similar between rat and human brainwaves mean there’s currently no reason to think humans respond any differently. “We're getting an increasing number of the cells moving into the sleep state and that could potentially -- it doesn't prove it -- but it could potentially explain the decrease in performance that is so common in humans and other animals when we're not getting enough sleep.” (Image source: Wikimedia Commons) This half sleep is different from dozing. The rats were kept alert by being given new toys to keep their attention. The researchers suggested the animals might have been impaired before they even felt sleepy. A blogger for Bottom Line gives us the takeaway message. “While we all like to do as much as we can and feel something akin to mental toughness as we go that extra mile late into the night, it might not be worth it, for the work we produce will not necessarily be up to snuff.” While different people need different amounts of sleep, the researchers say the old standard of eight hours is still about average.

This episode of Somebody Lied To You is all about alcohol. Does alcohol kill your brain cells? Does alcohol shrink your brain cells? What are the longterm effects of drinking? We answer those questions and many, many more. I can't think of anyone that hasn't had someone say to them, "alcohol kills brain cells." It is a common thing for people to say. But does that argument really hold water? The biology can a little complex, especially when you start getting into neurons, bacteria, synapses, and the cell anatomical structure... but hey, you don't need to be scientist to understand the information we present here. You SHOULDN'T NEED to be a scientist. This is good stuff to know. Somebody Lied To You is brought to you by Ranker.

Here's a moment of pure stupidity. Common sense can go straight out the window in this case. A total lack of brain cells.

It may sound like the plot of a medical drama, but this approach to fighting cancer is real. Scientists say they may someday be able to battle brain cancer, while using a virus to do it. Early results from the lab are promising.
