That is going to wrap it up for biz this hour. Lets get you a check now of the markets. The chair of the u. S. Senate Intelligence Committee has accused the cia of secretly searching the committees computers, and removing documents. The director john brennan denies his staff acted improperly. Without prior notification or approval, cia personnel had conducted a search, that was John Brennans word, of the committee computers at the offsite facility. The committee has been investigating charges the cia used Excessive Force in questioning terror suspects after the 9 11 attacks. Chair Dianne Feinstein said the committee have been examining the allegations since 2009. Internal documents related to the interrogations were made available by the cia on computers at a leased facility. Feinstein says the agency later searched not only those computers, but the committees internal network, as well. She condemned the move, saying they may have violated the separation of powers principle, embodies in the u. S. Constitution. The agency chief has denied the accusations. As far as the allegations of, you know, cia hacking into, you know, senate computers, nothing could be further from the truth. We wouldnt do that.

Some newly obtained data is providing a clearer picture of the Nuclear Accident at Fukushima Daiichi. It shows how radiation levels near the plant rose before a hydrogen explosion. 14 monitoring posts recorded radiation levels every 20 seconds after the earthquake and tsunami that damaged the plant three years ago.

At 2 40 the readings briefly hit 4. 6 millisieverts per hour. Thats the highest mark that day. An hour later, there was a hydrogen explosion, at reactor number 1. Translator information may lead researchers to new discoveries. We would like to get as much data as possible. At the time, crews were trying to reduce pressure within the reactors containment vessel, performing an operation called ventwork. He says that may have caused radiation levels to rise. A u. S. Nuclear expert says operators need to be prepared for accidents at nuclear plants. But Gregory Jaczko says theres no way to completely prevent them. People have to focus more on the consequences of the accident. Look at ways not just to reduce the chance of an accident happening, but to really look at the fundamental design of the reactors to see what can be done to actually prevent or reduce the consequences that we saw from the Fukushima Daiichi accident. Jaczko said restarting plants in japan wont be justified unless the public supports the move. All 48 commercial reactors are offline. Utilities have applied for government safety screening to resume operations at more than a third of them. Shogi is a traditional japanese board game similar to chess.

He managed to beat the computer with ease. But he worked hard to make it better. Now his program can evaluate moves much faster than the human brain. Translator humans can only think of ten moves per second. But my program can calculate more than 4 million moves. Reporter his efforts paid off last year. After five years, he finally claimed an historic victory over professional player. His program went on to beat 17 others in a computer shogi tournament last november.
