OTTAWA (Reuters) - Red-faced officials at Canada’s nuclear safety watchdog on Thursday said they were probing how a hacker had managed to litter its official Web site with dozens of colour photographs of a nuclear explosion.
The Ottawa Citizen newspaper said every media release on the Canadian Nuclear Safety Commission’s Web site had been labelled as a security breach on Wednesday. When opened, each document had a headline reading “For immediate release” and underneath was a large photo of an exploding atomic bomb.
“We are in discussions with the (Internet service) provider. When we were informed the Web site had been tampered with, we immediately disabled the media module,” said commission spokesman Aurel Gervais, dismissing the suggestion that the hacker had been able to access secret information.
“The external Web site was the only Web site that was tampered with. There was no internal information that was compromised,” he said.
The media site at http://www.nuclearsafety.gc.ca/eng/media/ was working normally on Thursday.
The Citizen — which published a colour photograph of one of the tampered pages — said the hacker had left a message saying “Please dont (sic) put me in jail … oops, I divided by zero”.
TOKYO (AFP) - For people who want to ensure their words last for their progeny, Japanese scientists have found a way to literally put a message into genes.
A research team said this week it had developed a technology for storing digital data in the DNA of bacteria, which unlike most living organisms can survive for millennia in the right conditions.
Each hay bacillus bacterium can store two megabits — the equivalent of 1.6 million Roman letters. The scientists can take out the microscopic implants in a laboratory and read them so they appear as ordinary text.
The team at Keio University’s Institute for Advanced Biosciences said the technology needs to be perfected but that it was optimistic about its future uses.
“If I wanted to store my personal diary in these live bacteria and take it with me to my grave, then my story can live for thousands and thousands of years,” head researcher Yoshiaki Ohashi said with a laugh.
In practical terms, the technology could eventually benefit companies such as pharmaceutical makers which want to “stamp” their brand.
“In doing so, the company can detect piracy and protect its patent. They can also store information at one specific area of the gene and retrieve it from there,” Ohashi said.
The researchers insert the data at four different places so even if one is disrupted, there would be backup.
But the team said they still needed to work before the technology could go on the market. In particular, the scientists need to ensure that the DNA will not be altered as live bacteria naturally evolve.
Hay bacillus bacteria are generally found in soil or decaying matter and are especially resistant to extreme weather.
