Ancient coin shows Cleopatra was no beauty

‘Antony and Cleopatra — one of history’s most romantic couples — were not the great beauties that Hollywood would have us believe, according to British academics.

A study of a 2,000-year-old silver coin found the Egyptian queen, famously portrayed by a sultry Elizabeth Taylor, had a shallow forehead, pointed chin, thin lips and sharp nose.

On the other side, her Roman lover, played in the 1963 movie by Richard Burton, Taylor’s husband at the time, had bulging eyes, a hook nose and a thick neck.

History has depicted Cleopatra as a great beauty, befitting a woman who as Queen of Egypt seduced Julius Caesar, and then his rival Mark Antony.

But the coin, which goes on show on Wednesday at Newcastle University for Valentine’s Day, after years lying in a bank, is much less flattering about both famous faces.’

Scientists probe ‘hole in Earth’

‘Scientists are to sail to the mid-Atlantic to examine a massive “open wound” on the Earth’s surface.

Dr Chris MacLeod, from Cardiff University, said the Earth’s crust appeared to be completely missing in an area thousands of kilometres across.

The hole in the crust is midway between the Cape Verde Islands and the Caribbean, on the Mid-Atlantic Ridge. [..]

Dr MacLeod said the hole in the Earth’s crust was not unique, but was recognised as one of the most significant.

He said it was an “open wound on the surface of the Earth”, where the oceanic crust, usually 6-7km thick (3.7-4.3 miles), was simply not there.’

Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says

‘Simultaneous warming on Earth and Mars suggests that our planet’s recent climate changes have a natural—and not a human-induced—cause, according to one scientist’s controversial theory.

Earth is currently experiencing rapid warming, which the vast majority of climate scientists says is due to humans pumping huge amounts of greenhouse gases into the atmosphere.

Mars, too, appears to be enjoying more mild and balmy temperatures.

In 2005 data from NASA’s Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide “ice caps” near Mars’s south pole had been diminishing for three summers in a row.’

Vitamins ‘could shorten lifespan’

‘Taking certain vitamin supplements may adversely affect people’s lifespan, researchers have suggested.

Millions worldwide use antioxidant supplements such as vitamins A and E, and beta-carotene.

Looking at dozens of previous studies, Copenhagen University researchers suggested these appeared to raise, not lower, the risk of early death.

A supplements industry expert said the Journal of the American Medical Association study was fatally flawed.

But nutritionists said it reinforced the need to eat a balanced diet, rather than relying on supplements.’


Prescription abuse to pass illicit drugs

‘Abuse of prescription drugs is about to exceed the use of illicit street narcotics worldwide, and the shift has spawned a lethal new trade in counterfeit painkillers, sedatives and other medicines potent enough to kill, a global watchdog warned Wednesday.

Prescription drug abuse already has outstripped traditional illegal drugs such as heroin, cocaine and Ecstasy in parts of Europe, Africa and South Asia, the U.N.-affiliated International Narcotics Control Board said in its annual report for 2006.

In the United States alone, the abuse of painkillers, stimulants, tranquilizers and other prescription medications has gone beyond “practically all illicit drugs with the exception of cannabis,” with users increasingly turning to them first, the Vienna-based group said.’


The Asteroid Threat is Out There

‘Friday the 13th of April 2029 could be a very unlucky day for planet Earth. At 4:36 a.m. Greenwich Mean Time, a 25-million-ton, 820-foot-wide asteroid called 99942 Apophis will slice across the orbit of the moon and barrel toward Earth at more than 28,000 mph. The huge pockmarked rock, two-thirds the size of Devils Tower in Wyoming, will pack the energy of 65,000 Hiroshima bombs — enough to wipe out a small country or kick up an 800-foot tsunami.

On this day, however, Apophis is not expected to live up to its namesake, the ancient Egyptian god of darkness and destruction. Scientists are 99.7 percent certain it will pass at a distance of 18,800 to 20,800 miles. [..] We will have dodged a cosmic bullet.

Maybe.’

A Shock to the System

‘Team Hubris is installing a deep brain stimulator, essentially a neurological pacemaker, in my head. This involves threading two sets of stiff wires in through my scalp, through my cerebrum — most of my brain — and into my subthalamic nucleus, a target the size of a lima bean, located near the brain stem. Each wire is a little thinner than a small, unfolded paper clip, with four electrodes at one end. The electrodes will eventually deliver small shocks to my STN. How did I get into this mess? Well, I have Parkinson’s disease. If the surgery works, these wires will continually stimulate my brain in an attempt to relieve my symptoms.’

Bird-brained Chinese scientists learn to fly pigeons

‘Scientists in eastern China say they have succeeded in controlling the flight of pigeons with micro electrodes planted in their brains, state media reported on Tuesday.

Scientists at the Robot Engineering Technology Research Centre at Shandong University of Science and Technology said ther electrodes could command them to fly right or left or up or down, Xinhua news agency said.

“The implants stimulate different areas of the pigeon’s brain according to signals sent by the scientists via computer, and force the bird to comply with their commands,” Xinhua said. [..]

The report did not specify what practical uses the scientists saw for the remote-controlled pigeons.’


Japanese whale hunt ended early

‘Japan’s whaling fleet has cut short its hunt in the Antarctic after a fire two weeks ago crippled the main boat.

The controversial annual hunt, which Japan says was carried out for research purposes, was meant to continue until the end of March.

But Japan’s Institute of Cetacean Research said the Nisshin Maru boat could not be fully repaired at sea.’

Antarctic ice melt reveals exotic creatures

‘Spindly orange sea stars, fan-finned ice fish and herds of roving sea cucumbers are among the exotic creatures spied off the Antarctic coast in an area formerly covered by ice, scientists reported Sunday.

This is the first time explorers have been able to catalog wildlife where two mammoth ice shelves used to extend for some 3,900 square miles over the Weddell Sea.

At least 5,000 years old, the ice shelves collapsed in two stages over the last dozen years. One crumbled 12 years ago and the other followed in 2002.’


How to make wicked hash

‘Making hash is easier than you think!

Making hash is an ancient art. The first proto-human who rubbed her fingers together after handling a mature cannabis bud was making hash in much the same way it is made today. Although the process of removing the resins from cannabis have become more refined, the essence has remained unchanged for millennia.

Making hash is the process of extracting and preserving the psychoactive resins from the cannabis plant. These resins are found primarily on tiny glands called trichomes, which under a magnifying glass look like mushrooms – a head on top of a stalk. These trichomes are part of what gives cannabis buds their “frosty” appearance.’


Watchdog blasts ‘X-treme Eating’

‘Chain restaurants in the United States are promoting dangerous “X-treme Eating”, a US watchdog has said.

They are serving up “ever-more harmful new creations,” says the Center for Science in the Public Interest.

It says that some individual dishes can exceed 2,000 calories, more than the recommended daily intake for women. [..]

“Rather than compete to make their products healthier, restaurant chains are competing with each other to make their appetizers, main courses, and desserts bigger, badder, and cheesier than ever before,” a CPSI statement said.’


How UK attempted bizarre X-Files tests on soldiers

‘The Ministry of Defence funded a secret study to ascertain whether people with psychic powers could help protect the nation, it emerged last night.

The MoD arranged the tests to discover whether volunteers were able to use psychic powers to “remotely view” hidden objects. The studyinvolved blindfolding test subjects and asking them to “see” the contents of sealed brown envelopes containing pictures of random objects and public figures.

Defence experts tried to recruit 12 “known” psychics who advertised their abilities on the internet, but when they all refused they were forced to use “novice” volunteers.

The MoD last night defended the cost of the experiment, carried out in 2002, in which commercial researchers were contracted at a cost of £18,000 to test them to see if psychic ability existed in case it could be used in defence [..]’

Australia rocked by ‘lesbian’ koala revelation

‘Female koalas indulge in lesbian “sex sessions”, rejecting male suitors and attempting to mate with each other, sometimes up to five at a time, according to researchers.

The furry, eucalyptus-eating creatures appear to develop this tendency for same-sex liaisons when they are in captivity. In the wild, they remain heterosexual.

Scientists monitoring the marsupials with digital cameras counted three homosexual interactions for every heterosexual one.’


1 In 3 Boys Heavy Porn Users, Study Shows

‘Is your child watching to porn? You may be surprised.

According to a new study by the University of Alberta, boys aged 13 and 14 living in rural areas, are the most likely of their age group to access pornography.

The study found that parents need to be more aware of how to monitor their children’s viewing habits.

Students were surveyed anonymously about how and how often they accessed sexually explicit media content on digital or satellite television, video and DVD and the Internet. Ninety percent of males and 70 percent of females reported accessing sexually explicit media content at least once. More than one-third of the boys reported viewing pornographic DVDs or videos “too many times to count”, compared to eight percent of the girls surveyed.’


Iran Launches First Space Rocket

‘State television reports that Iran has successfully launched its first space rocket. Fars news agency quotes the deputy head of Iran’s aerospace research centre, Ali Akbar Golrou, as saying the rocket reached an altitude of 150 kilometres, but did not stay in orbit. [..]

Bahrami, told state television that the rocket was carrying “material intended for research created by the ministries of science and defense.” Bahrami added, “All the tests [prior to the launch] have been carried out in the country’s industrial facilities in line with international regulations.” [..]

The announcement of the rocket launch comes at a time of growing tension between Iran and the West over Tehran’s nuclear program. [..]’

Only human – the biggest risk factor in long-term space missions

‘ What’s the biggest hurdle to setting up a colony on the Moon or getting mankind to Mars and beyond? Aliens? Asteroids? Money? Try: humans themselves. Experts poring over plans to return to the Moon by 2018 and later stride to Mars believe the greatest-ever gamble in the history of space may ultimately depend on keeping the mind and body sound.

Anxiety, loneliness and tensions with crewmates, a daily battle to maintain fitness and avoid accidents, DNA-shredding radiation from solar flares or cosmic rays — all these make mental and physical health the key to whether a long-term mission will succeed or fail catastrophically.

Benny Elmann-Larsen, coordinator of physiology in human space flight at the European Space Agency (ESA), says psychological stress could be the biggest problem of all.’


Drug Test 911

‘The following system is provided as a free service for anyone researching different ways to pass a drug test. This system explains how to successfully pass a standard urine drug test using simple items you either have at home or can purchase at a grocery or drug store. It also explains how to successfully pass a hair drug test. The system is mainly designed for low to moderate-level users who will be taking a drug test at least 8 DAYS in the future.’


Chimps Observed Making Their Own Weapons

‘Chimpanzees living in the West African savannah have been observed fashioning deadly spears from sticks and using the hand-crafted tools to hunt small mammals — the first routine production of deadly weapons ever observed in animals other than humans.

The multi-step spear-making practice, documented by researchers in Senegal who spent years gaining the chimpanzees’ trust, adds credence to the idea that human forebears fashioned similar tools millions of years ago.

The landmark observation also supports the long-debated proposition that females — the main makers and users of spears among the Senegalese chimps — tend to be the innovators and creative problem solvers in primate culture.’

Pot not hot: weed losing its cool

‘Smoking a joint is no longer cool among the young, according to a new poll, which found one in three regard it as unacceptable.

A study by the National Drug and Alcohol Research Centre found marijuana had become socially unfashionable in the same way as cigarettes.

“Clearly, it’s not as acceptable as it once was to be stoned,” said Paul Dillon, a spokesman for the centre at the University of NSW.’

I don’t know what’s wrong with kids today. :)


Science finds new ways to regrow fingers

‘Researchers are trying to find ways to regrow fingers – and someday, even limbs – with tricks that sound like magic spells from a Harry Potter novel.

There’s the guy who sliced off a fingertip but grew it back, after he treated the wound with an extract of pig bladder. And the scientists who grow extra arms on salamanders. And the laboratory mice with the eerie ability to heal themselves.

This summer, scientists are planning to see whether the powdered pig extract can help injured soldiers regrow parts of their fingers. And a large federally funded project is trying to unlock the secrets of how some animals regrow body parts so well, with hopes of applying the the lessons to humans.’


Suppressed report shows cancer link to GM potatoes

‘Campaigners against genetically modified crops in Britain last are calling for trials of GM potatoes this spring to be halted after releasing more evidence of links with cancers in laboratory rats.

UK Greenpeace activists said the findings, obtained from Russian trials after an eight-year court battle with the biotech industry, vindicated research by Dr Arpad Pusztai, whose work was criticised by the Royal Society and the Netherlands State Institute for Quality Control.

The disclosure last night of the Russian study on the GM Watch website led to calls for David Miliband, the Secretary of State for Environment, Food and Rural Affairs, to withdraw permission for new trials on GM potatoes to go ahead at secret sites in the UK this spring. [..]’


$82 Buys E-Voting Secrets

‘For a mere $82 a computer scientist and electronic voting critic managed to purchase five $5,000 Sequoia electronic voting machines over the internet last month from a government auction site. And now he’s taking them apart.

Princeton computer science professor Andrew Appel and his students have begun reverse-engineering the software embedded in the machines’ ROM chips to determine if it has any security holes. But Appel says the ease with which he and his students opened the machines and removed the chips already demonstrates that the voting machines are vulnerable to unauthorized modification.

Their analysis appears to mark the first time that someone who hasn’t signed a non-disclosure agreement with Sequoia Voting Systems has examined one of its machine’s internals.’


Google to rule the Earth

‘In a speech Friday night to the Annual American Association for the Advancement of Science conference, Google co-founder Larry Page let slip with a truth we all suspected:

“We have some people at Google [who] are really trying to build artificial intelligence (AI) and to do it on a large scale…It’s not as far off as people think.”

Yep, you read that right, Google is trying to build real AI. The worlds most dominant online company, with the largest conglomeration of computing power the world has ever seen, is trying to build artificial intelligence, and according to Page it isn’t that far away either. The term Googlebot is about to take on a whole new meaning, and in the not to distant future as well.’

Drug rape myth exposed as study reveals binge drinking is to blame

‘Women who claim to be victims of ‘date-rape’ drugs such as Rohypnol have in fact been rendered helpless by binge-drinking, says a study by doctors.

They found no evidence that any woman seeking help from emergency doctors because their drinks were allegedly spiked had actually been given these drugs. [..]

Around one in five tested positive for recreational drugs while two-thirds had been drinking heavily.

The findings further erode the theory that there is widespread use of Rohypnol and GHB, another drug said to be favoured by predatory rapists.’
