Atom Smasher Could Be Used As Time Machine, Physicists Propose

In a 'long shot' theory, physicists propose that the world's largest atom smasher could be used as a time machine to send a special kind of matter backward in time.

Radiation Can Be Good For You

Let’s stop panicking about radiation. This message is aimed at my friend A. F. who told me to shut the windows despite the warmth of the morning. “I calculate that the radioactive death cloud from the Fukushima nuclear plant will arrive here by noon,” he explained.

Radiation Can Be Good For You






Let’s stop panicking about radiation. This message is aimed at my friend A. F. who told me to shut the windows despite the warmth of the morning. “I calculate that the radioactive death cloud from the Fukushima nuclear plant will arrive here by noon,” he explained.


I doubted that shutting the windows would provide enough protection, but I’m no expert, so I did as he told me. Around 11:50 p.m., he leapt to his feet and pointed through the glass. “There it is, right on schedule,” he said. I followed the line of his finger, and said: “That’s not a radioactive emission from Japan. That’s just a cloud.”



None of this surprised me. The main thing that happens after a disaster is that panic arises among people who enjoy that sort of thing. An hour later, A. F. claimed he could smell radiation. I pointed out that 1.) Radiation doesn’t have a smell, and, 2.) He lives above a hairdresser’s, a category of shop which always smell disgusting, because they use so many chemicals that the fumes combine into a lethal cloud way worse than Fukushima and closer to Bhopal.



Discussing this later at the bar, I was curious to learn from a self-described scientist that some boffins now think radiation is good for you. I retorted: “The residents of Hiroshima might disagree.” But then I remembered that I myself owned a historical document showing radiation having a positive effect: an April 1963 edition of The Amazing Spiderman. 



The scientist clarified himself: Low level radiation is good for you. With his iPhone, he Googled several surveys which showed that radiologists, nuclear plant staff and airport security staff get fewer cancers than people in jobs with no exposure to radiation.



Most surprising was a recent study in Florida in which mice suffering from Alzheimer’s disease were given two hours of “talk time” on mobile phones (which emit low levels of radiation) every day for seven months. “Memory problems of the older Alzheimer’s mice disappeared,” researchers at the University of South Florida said.



Irritatingly, the report failed to answer the obvious questions. 1) How did they locate mice with Alzheimer’s disease in the first place? Did they hang out at mice apartments to see which ones remembered their door entry codes? 2) What did the mice talk about for two hours a day? 3) How did they know which mice had memory problems? Did they eavesdrop on their conversations? Mouse one: “My brain works perfectly again.” Mouse two: “Is that right?” Mouse one: “Is what right?”



The next day was so hot that A. F. reluctantly opened the windows, even though the Fukushima radioactive death cloud was running late. I told him not to worry. “There are lots of documents which indicate that low-level radiation has positive effects,” I said, handing him a reading list: Godzilla, Spider-Man, the Fantastic Four, the Silver Surfer, the Incredible Hulk, the Daleks, etc. You can’t deny evidence like that.



I could have added that radioactivity has been scientifically proven to benefit mouse-sized brains, but I stopped myself. For several of my dear friends, that would have been a little too close to the truth.

Major Tsunami Damage In N. Japan after 8,9 Quake




Japan was struck by a magnitude 8.9 earthquake off its northeastern coast Friday, unleashing a 13-foot (4-meter) tsunami that washed away cars and tore away buildings along the coast near the epicenter. There were reports of injuries in Tokyo.


In various locations along Japan's coast, TV footage showed massive damage from the tsunami, with dozens of cars, boats and even buildings being carried along by waters. A large ship swept away by the tsunami rammed directly into a breakwater in Kesennuma city in Miyagi prefecture, according to footage on public broadcaster NHK.



Officials were trying to assess damage, injuries and deaths from the quake but had no immediate details.



The quake that struck at 2:46 p.m. was followed by a series of powerful aftershocks, including a 7.4-magnitude one about 30 minutes later. The U.S. Geological Survey upgraded the strength of the first quake to a magnitude 8.9, while Japan's meteorological agency measured it at 7.9.



The meteorological agency issued a tsunami warning for the entire Pacific coast of Japan. NHK was warning those near the coast to get to safer ground.



The Pacific Tsunami Warning Center in Hawaii said a tsunami warning was in effect for Japan, Russia, Marcus Island and the Northern Marianas. A tsunami watch has been issued for Guam, Taiwan, the Philippines, Indonesia and the U.S. state of Hawaii.



The quake struck at a depth of six miles (10 kilometers), about 80 miles (125 kilometers) off the eastern coast, the agency said. The area is 240 miles (380 kilometers) northeast of Tokyo.



In downtown Tokyo, large buildings shook violently and workers poured into the street for safety. TV footage showed a large building on fire and bellowing smoke in the Odaiba district of Tokyo.



In central Tokyo, trains were stopped and passengers walked along the tracks to platforms.



The ceiling in Kudan Kaikan, a large hall in Tokyo, collapsed, injuring an unknown number of people, NHK said.



Footage on NHK from their Sendai office showed employees stumbling around and books and papers crashing from desks. It also showed a glass shelter at a bus stop in Tokyo completely smashed by the quake and a weeping woman nearby being comforted by another woman.



Several quakes had hit the same region in recent days, including a 7.3 magnitude one on Wednesday.



Thirty minutes after the quake, tall buildings were still swaying in Tokyo and mobile phone networks were not working. Japan's Coast Guard has set up task force and officials are standing by for emergency contingencies, Coast Guard official Yosuke Oi said.



"I'm afraid we'll soon find out about damages, since the quake was so strong," he said
