US software behemoth Microsoft has doubled a cash reward for information on the whereabouts of a Canadian boy who ran away from home after his father took away his Xbox game console, it said Tuesday.
Whether we choose to admit it or not, we all experience memory errors from time to time. Research has suggested that false memory may be a result of having too many other things to remember or perhaps if too much time has passed. However, previous studies have indicated that a specific type of false memory known as "boundary extension" occurs for different reasons. Boundary extension is a mistake that we often make when recalling a view of a scene - we will insist that the boundaries of an image stretched out farther than what we actually saw. Although this error is very common and occurs in people of all ages (from young children to the elderly), few studies have been done examining how quickly boundary extension occurs. That is, it was unknown how long a scene needs to be interrupted before the viewer experiences boundary extension and is convinced they saw more than they actually did.
Just when it seemed that contaminated vegetables posed a bigger risk of food poisoning than eating meat, along comes a pathogen that will only attack those of us who are carnivores.
The bacterium - a strain of Escherichia coli - makes a toxin that does its worst by latching onto a sugar molecule that humans don't have naturally. We can, only acquire it by eating red meat or dairy products.
"This toxin originally evolved to attack cattle or some other animals," says Ajit Varki, an expert in molecular medicine at the University of California, San Diego, who was involved in the study. By eating the toxin's intended target we made ourselves vulnerable too, he says.
When unlucky meat-eaters ingest this particular E. coli strain, its toxin kills the cells that line the gut, eventually causing bloody diarrhoea, Varki says. It also heads for blood vessels and the kidneys.

Fungus expert Joan Bennett did not believe in so-called toxic mould - the cause of "sick building syndrome" and many lawsuits - until her New Orleans home was flooded during Hurricane Katrina in 2005.
When she got a whiff of the foul air that the black goo had created in her home, she decided to change her research focus and try to find out how and if the fungi that took over most of the flooded homes on the Gulf Coast might make people ill.

The death toll in Guinea-Bissau's rapidly spreading cholera epidemic is rising and the outbreak may continue for months, United Nations agencies said on Tuesday.
The death toll is now 213, with 12,785 people known to be infected, the U.N. Office for the Coordination of Humanitarian Affairs told a news briefing in Geneva.

Eleven cases connected to single Niagara restaurant, but officials concerned about source of four other incidents
Ontario's second E. coli outbreak this month continues to grow, and although a restaurant has been pinpointed as a possible source, officials fear "something broader" could be behind it.

Bulawayo-At least 8 people have died of cholera and 30 have been hospitalised in Esigodini, 40 kilometres outside of Bulawayo on the Johannesburg-Bulawayo highway.
A fifth case has been confirmed in the recent outbreak of febrile illnesses caused by a mysterious virus in South Africa, and preliminary tests have supported earlier suspicions that it is new member of the arenavirus family, South African health officials announced recently.
A worker who fell ill and died after cleaning a hospital room where the first case-patient in the outbreak had stayed was confirmed to have the virus, South Africa's National Institute for Communicable Diseases (NICD) said in an Oct 24 update.

New research has found that people who view pictures of someone they hate display activity in distinct areas of the brain that, together, may be thought of as a 'hate circuit.'
New research has found that people who view pictures of someone they hate display activity in distinct areas of the brain that, together, may be thought of as a 'hate circuit.'
The study, by Professor Semir Zeki and John Romaya of the Wellcome Laboratory of Neurobiology at UCL, examined the brain areas that correlate with the sentiment of hate and shows that the 'hate circuit' is distinct from those related to emotions such as fear, threat and danger - although it shares a part of the brain associated with aggression. The circuit is also quite distinct from that associated with romantic love, though it shares at least two common structures with it.
Club foot, one of the most common birth defects, may be caused by a genetic mutation, a finding that opens the door to genetic counselling, prevention and treatment, researchers said Thursday.
Club foot - in which the foot turns inward and downward, making walking difficult - is one of the most common severe musculoskeletal birth defects, with a worldwide incidence of one in 1,000 live births, according to the researchers.
About half of club foot cases affect both feet, including the bones, muscles, tendons and blood vessels.
If untreated, those affected walk on the outside of their feet, which can lead to long-term pain and disability. Treatments include the use of casts and splints, or surgery.
