How many Facebook friends is too many?

The internet has created the illusion of mass intimacy, but 151 friends is an unmanageable number, says an academic

Friends in costume drinking punch through straws

It’s the internet world now, so you can speak to anyone anywhere in the world — right? Blog away, and every Tom, Dick and Harriet from Anchorage to Cape Town can admire your wit, marvel at your wisdom and might even offer a comment in return. Sign them up to your Facebook site, where you can now boast 300, 500, 1,000 friends.

But how well do you really know all these people? Would you really respond with a cheque for £50 to an e-mail plea from one of them? OK, OK, I know a surprising number of people get hoodwinked by 15-year-old Nigerian spammers on a cranky old village internet connection, but I’ll warrant that most of you aren’t so gullible — and it’s precisely because you don’t treat everyone on your Facebook list as equally worthy of interest.

ITV fined over jungle rat killing

Amplifyd from uk.news.yahoo.com

ITV has been fined for animal cruelty after contestants on I’m A Celebrity… Get Me Out Of Here! killed and ate a rat. Skip related content

Celebrity chef Gino D’Acampo and Hollyoaks actor Stuart Manning killed the animal with a knife when they were left without meat during the reality series.

Chief Inspector David Oshannessy, from the RSPCA, said ITV was fined 3,000 Australian dollars (£1,903) and will pay 2,576 dollars (£1,634) in costs.

He said: “It’s a reasonable result. It reflects the fact that all animals are protected by the Prevention Of Cruelty To Animals Act.

“The animal was killed for a TV show - that’s not appropriate. The raw footage indicates that, from the first attempt, it took about 90 seconds before it actually died.

“The legislation says that an animal can be killed for human consumption provided it does not cause unnecessary suffering. Had it been killed and it was over and done with, we might not be having this conversation.”

Haiti charity single goes on sale

Amplifyd from uk.news.yahoo.com

A star-studded charity cover of REM’s Everybody Hurts has been released to raise money for Haiti earthquake victims. Skip related content

Under the guidance of X Factor supremo Simon Cowell, some 21 acts united to record the single, including Leona Lewis, Susan Boyle and Kylie Minogue.

The moving ballad goes on sale in the shops on Monday with those behind it hoping it will top the charts and provide much needed funds in the process.

Originally a hit in 1993, the song has been reworked with vocalists including X Factor winner Joe McElderry, Rod Stewart and JLS. The recording also reunites Robbie Williams with his former Take That bandmates Gary Barlow and Mark Owen.

REM are waiving royalty rights to the charity track, while the Government has said that there will be no VAT cut. Proceeds will be split between the Disasters Emergency Committee (DEC) and The Sun’s Helping Haiti campaign.

Fizzy drinks ‘increase cancer risk’

Fizzy drinks ‘increase cancer risk’

Sugary soft drinks can dramatically increase the risk of pancreatic cancer, research suggests. Skip related content

Fizzy drinks 'increase cancer risk'

As little as two soft drinks consumed a week can almost double the chances of developing the disease, one of the most deadly forms of cancer, a study found.

Scientists believe the high sugar content of many soft drinks may explain the trend.

Since pancreatic cancer is relatively rare - affecting around 7,600 people each year in the UK - the absolute risk from soft drinks is small.

However those diagnosed with the disease have a poor prognosis. Only 2% to 3% of patients in the UK survive as long as five years.

Researchers based their findings on more than 60,500 participants recruited for a large-scale health study in Singapore.

Beer could help prevent weak bones

Beer is a rich source of a nutrient that can help prevent weak bones - but it depends what type you drink, researchers said. Skip related content

Beer could help prevent weak bones

As one of the nation’s favourite drinks, beer is a rich source of dietary silicon, which can help cut the chance of developing diseases like osteoporosis, they said.

However, not all beers are the same, with those containing malted barley and hops having higher silicon content than beers made from wheat.

Some light lagers made from grains like corn have the lowest levels of silicon while beers made from hops seem to come out on top, according to the study from researchers at University of California, Davis.

Their research, published in the Journal of the Science of Food and Agriculture, involved examining 100 commercial beers and their production methods.

The experts said beer was a major source of dietary silicon - roughly half of the silicon in beer can be readily absorbed by the body.

Looking younger is in the genes

Scientists have found the gene which could be the key to looking younger or older than we really are, they said. Skip related content

Looking younger is in the genes

Researchers from the University of Leicester and King’s College London made the breakthrough as part of research into the relationships between certain diseases with biological rather than chronological age.

British Heart Foundation Professor of Cardiology at the University of Leicester, Professor Nilesh Samani, who co-led the project, said chronological ageing is how old someone is in years, whereas biological age reflects whether the cells of some people are older or younger than suggested by their actual age.

He said: “There is accumulating evidence that the risk of age-associated diseases including heart disease and some types of cancers are more closely related to biological rather than chronological age.

“What we studied are structures called telomeres which are parts of one’s chromosomes.

The phantom promise

Amplifyd from www.timesonline.co.uk

Research on amputees has shown that the brain can be tricked into feeling pain. The process could be reversible

ouch something sharp like a pin and it will hurt. Maybe quite a lot, depending on how hard you press on it. Another person doing the same will have to endure the kind of shooting pain that you did.

The idea that people’s perception of the world is built from their senses — how we see, smell, hear and touch things — has long been held as the essence of experience. The sensory data is transmitted along nerves to the brain, where it is decoded and converted into a speeding car, a shrill alarm or a sharp pin prick.

But studies of pain and the brain have, over the past few decades, shown the striking limitations of this conventional view.

Arrested development

The field of neurocriminology is reviving some controversial ideas. Can criminal urges really be blamed on the brain?

16 Mar 2007, Marlin, Texas, USA --- Inmates wait to enter their dormitory at The Marlin Orientation and Assessment Unit, a Texas Youth Commission facility.

We are used to hearing talk of “the criminal mind”. In future we can expect to hear more about “the criminal brain”. Recent scientific research suggests that criminality may be a trait tha t some people are born with or acquire very early in life. It’s an unsettling thought: examine the prefrontal cortex in the brain of a gurgling infant and you may see the signs of a potential future murderer.

Scholarly interest in the criminal cranium is by no means new. In 1871 the Italian physician and intellectual Cesare Lombroso was performing a post-mortem on the body of a notorious bandit named Giuseppe Villela when he became intrigued by the shape of the skull, which reminded him of those of “apes, rodents and birds”. Lombroso had a flash of insight.

Science shows that women need more sleep

Amplifyd from www.timesonline.co.uk

New research reveals that women need twenty minutes more sleep than men per night but many aren’t getting it

s sleep a feminist issue? Our observations at the Sleep Research Centre at Loughborough University suggest that this might well be the case. Women tend to work their brains harder than men, and need more sleep as a result — typically around 20 minutes a night more than men. They particularly work the part of the brain called the cerebral cortex — responsible for intelligence, language, memory and consciousness — because, unlike men, they switch from one task to another. Selecting which information to attend to — deciding on actions and priorities — works the cerebral cortex hard. This is far more taxing than, say, completing tasks sequentially during the day.

The type of sleep that helps the cerebral cortex recover most is deep sleep — the third and fourth stage of non-rapid eye movement sleep.
