Why eating red meat may be hazardous for your health

Thursday, October 30th, 2008

An international research team has given two reasons why eating red meat could be bad for you: it increases risk of food poisoning in humans and a regular diet of the animal product can make people more susceptible to E. coli.

The study has been published in Nature.

According to University of California, San Diego School of Medicine professor Ajit Varki, M.D., the team has uncovered the first example of a bacterium that causes food poisoning in humans when it targets a non-human molecule absorbed into the body through red meats such as lamb, pork and beef.

In findings, the boffins discovered that a potent bacterial toxin called subtilase cytotoxin specifically targets human cells that have a non-human, cellular molecule on their surface.

The molecule -N-glycolylneuraminic acid (Neu5Gc) - is a type of glycan, or sugar molecule, that humans don’t naturally produce.

Subtilase cytotoxin is produced by certain kinds of E. coli bacteria, causing bloody diarrhea and a potentially fatal disease called haemolytic uraemic syndrome (HUS) in humans. Humans usually become infected after eating contaminated red meat, which is why this is also known as “hamburger” disease.

Varki, UC San Diego School of Medicine distinguished professor of medicine and cellular and molecular medicine, and co-director of the UCSD Glycobiology Research and Training Center, previously discovered that humans don’t produce Neu5Gc because they lack the gene responsible for its production. Therefore, it was thought that humans should be resistant to the toxin.

“Ironically, humans may set themselves up for an increased risk of illness from this kind of E. coli bacteria present in contaminated red meat or dairy, because these very same products have high-levels of Neu5Gc,” Nature quoted Varki, as saying.

“The Neu5Gc molecule is absorbed into the body, making it a target for the toxin produced by E. coli,” the expert added.

In the study, the researchers discovered that sites where the Neu5Gc has been incorporated into the human body coincide with toxin binding.

“When the toxin binds to the non-human Neu5Gc receptors, it can result in serious food-poisoning and other symptoms in humans,” said Varki.

The research emphasizes the need for people to eat only well-cook meat or pasteurized dairy products, processes that destroy contaminating bacteria.

Icelandic designer creates world’s first bulletproof handkerchief

Thursday, October 30th, 2008

Keeping in mind well-dressed gentlemen with dangerous lifestyles, an Icelandic designer has created the world’s first bulletproof handkerchief.

The life-saving accessory is made from Kevlar, which is five times stronger than steel.

It sits in the breast pocket in order to “protect the heart of men”, reports the Telegraph.

The material, which is used to make protective vests and Formula 1 cars, can withstand a bullet as well as temperatures of up to around 400 degrees centigrade.

Only ten of the stylish handkerchiefs are currently available, all in a tasteful yellow and bordered with either raw golden silk or citric French cotton.

The handkerchiefs cost around 94 pounds, but the designer, Sluli Recht, emphasises that he takes “no responsibility for schmucks and wooden-heads who feel compelled to test the endurance or resistance of the textile in any way”.

British team plan a 1,000 mph car

Saturday, October 25th, 2008

A British team is designing a car to break the 1,000 miles per hour speed barrier.

The current world record is 763 mph, set by Andy Green, a Royal Air Force fighter pilot and mathematician, in 1997.

Green and his team-mate Richard Noble, who directed the 1997 attempt, are now testing the new car in an aircraft hangar in Bristol. The 12 million pound car is called Bloodhound SSC, named after the British supersonic air defence missiles of the cold war era.

It will have a jet engine and a rocket booster. When run, a special accelerator will help the jet engine race up to 350 mph. Then the rocket booster will be fired.

At this point, a V-12 racing car engine will pump more than 1,000 kg of hydrogen peroxide into the booster, forcing the car to 1,000 mph in 20 seconds.

Green calculates the car can reach 1,050 mph, at which it can out-run a bullet fired from a Magnum .357 revolver.

To slow down, the car will use airbrakes and two parachutes to bring it to a rest.

The car is expected to be built in a year and the world record attempt may be expected in three years. Test sites are being checked out in South Africa, the US and Australia.

“It’s an opportunity to do something extraordinary in engineering terms and to be part of the very best land speed record attempt in the world,” a British newspaper quoted Green as saying.

The team plans to make public all information related to the making of the car to inspire a new generation of scientists in the country.

There are other teams which are planning to break Green’s land speed record. North American Eagle, a US project, is being designed to reach 800 mph. The Australian Invader 5R is about two years away from a 1,000 mph attempt. Spirit of America, a project of flying enthusiast Steve Fossett before he went missing last year, aims to breach the speed of 800 mph.

If you are fairly literate with computers and just want to learn more about the office suite, then you can just take an online computer training course to learn everything that you could want to know through a simple training program.

They are also a good thing to use if you are teaching someone more about Microsoft office. These programs make really good training aids.

Revolutionary test to detect genetic diseases in unborn children developed

Friday, October 24th, 2008

British scientists have developed a revolutionary “universal test” that can enable prospective parents to screen embryos to detect almost any genetic disease in unborn children.

The 1,500-pound “genetic MoT” may be available as early as next year.

The test will allow couples at risk of passing on gene defects to conceive healthy children using IVF treatment.

Its developers at the Bridge Centre in London claim that their test just takes some weeks from start to finish, and is suitable for couples at risk of almost any condition.

They say that their test can identify multiple genetic variations, so that scientists could screen for combinations that together confer higher risks of diabetes, heart disease or cancer.

Besides examining for mutations that cause serious disorders such as cystic fibrosis, muscular dystrophy and Huntington’s disease, the new test could also reveal an embryo’s future susceptibility to a host of other medical conditions.

The researchers say that parents could thus be told about their embryo’s future risk of developing Alzheimer’s disease, heart disease, or breast cancer.

The new test could also improve the chances of pregnancy for those who are infertile by selecting embryos that stand the best chance of developing normally.

“We are still validating it, but it is going to be a revolution if it works out. It makes genetic screening very much more straightforward,” Times Online quoted Professor Alan Handyside, who has pioneered the technique, as saying.

The new test involves creating embryos by IVF and removing a single cell from each when they are two days old. The cells are tested using a technique known as karyomapping before a healthy embryo is implanted.

While presently only two per cent of the 15,000 known genetic conditions can be identified in this way, the researchers believe that their test can increase the range of such detections in future.

However, Alan Thornhill, the scientific director of the Bridge Centre, said: “When you start looking for more than two or three traits, you’ve just got no chance of getting a match. You’d need thousands of embryos, and we don’t have a practical way of making thousands of embryos.”

Sober up

Friday, October 24th, 2008

If you are young, have a hectic social life where you drink and party every night, and have applied for a job, chances are you will lose out to someone who is a teetotaler. Yes, you heard right.

A random survey of 375 CEOs in the medium and large-scale private sector industries by ASSOCHAM threw up some startling facts. Almost 55 per cent of the CEOs interviewed said they would choose teetotalers over people who drink.

Why teetotalers? Whether hiring at entry level or mid level, the choice of recruiters has undergone a seachange. In fact, of the 375 CEOs, 206 said that they would recruit only those young boys and girls who observe total abstinence from alcohol.

The common perception among the CEOs questioned is that teetotalers are more productive, efficient and competent. They stick to deadlines and are good at time management.

Harsh Saxena*, operations head of an event management company in Okhla, which implemented the total abstinence rule six months ago, says, “The results are fabulous. Both efficiency and time management have improved”.

Says Sunil Arora*, director of an advertising agency in south Delhi, “Given a choice, I’d any day have a battalion of young people, but they shouldn’t be the regular drunkard types.” All for the better Debunking the myth that “creative types need to be two pegs down to think up marvelous concepts”, Devan Khattar*, art director in a Noida-based ad agency says, “My team members are workaholics and not drinkaholics.

” Sajjan Jindal, chairperson for JSW Steel, says, “I’ve been following the new policy for some time - teetotalers are ambitious, highly productive and specific about their target.” While some of the companies surveyed have already made a change in recruitment policies, other HR departments are keen to make ‘no drinking’ a cast-iron rule.

And if an employee is found to be downing a peg too many? The decision to fire such employees will in all probability come much later, says Koteshwar Prasad Dobhal, director PR, ASSOCHAM. ASSOCHAM secretary general Dr DS Rawat says, “As far as entry-level recruitment is concerned, lifestyle habits are influencing decision-making.” And the teetotalers are winning.

Nokia Joins Open-Source Trend for Mobile Platforms

Friday, October 24th, 2008

Google’s recent decision to open its Android mobile-device platform is just the tip of the iceberg when it comes to open-source plans for revolutionizing wireless environments worldwide.

Nokia’s transition of Symbian to a new, free licensing model is also well under way, according to executives attending this week’s Symbian Smartphone Show in London. Plans to establish a new Symbian Foundation with strong open-source underpinnings are expected to reach fruition during the first half of 2009, said AT&T Vice President Kris Rinne.

“Making the platform available in open source by June 2010 will only enhance its appeal to developers, solutions providers, and network operators around the world,” Rinne said.

Challenging Microsoft

Despite Nokia’s embrace of a free licensing model for Symbian and the opening of Android, Microsoft executives recently indicated that the software giant has no plans to abandon the proprietary nature of its Windows Mobile platform model or switch to a free licensing model. Rivals see Microsoft’s decision to stay the course as an opening for the introduction of new products that will go head-to-head with some of the more visible components of Microsoft’s proprietary mobile environment.

Code-named Fennec, Mozilla’s mobile iteration of Firefox has already arrived via an initial alpha release for the Nokia N800 and N810 Internet tablets. Though the Fennec development team says it is making great progress on a Windows Mobile version, it is not ready for general use. However, the group released new versions of Fennec for use on Windows, Mac OS X, and Linux desktops.

The development of a mobile OpenOffice platform for wireless devices is also in the works. Earlier this year, java.net opened a new project that aims to build a new set of tools for creating and updating OpenDocument format (ODF) documents in mobile devices. Though still in the early development stage, the new Java SE and Java ME platform tools eventually should enable mobile devices to interact with the ODF-compatible OpenOffice.org productivity suite.

Open MobileWe

Other industry observers see the current economic downturn as reason enough for many consumers to abandon proprietary mobile models for open-source alternatives. For example, push e-mail provider Funambol thinks RIM’s proprietary BlackBerry e-mail platform is vulnerable to cheaper open-source alternatives.

“A trend is that when people can get a mobile service for less, they will switch, when they can,” Funambol said. “For many people, this means no longer paying $30+ a month for BlackBerry service when they can get push e-mail and mobile sync for $5 or $10.”

Funambol CEO Fabrizio Capobianco notes that the mobile industry currently faces a new imperative to differentiate its offerings by enabling users to sync a wide range of mobile content — including push e-mail, photos, personal-information management data and document files. Capobianco thinks the answer is an open-source flavor of mobile e-mail he calls Open MobileWe, which in some respects follows Apple’s MobileMe platform for the iPhone, but adds a push capability to the mix.

“MobileMe has shone a bright spotlight on the large pent-up demand for the ability to easily sync and share mobile content,” Capobianco said. “Since MobileMe’s debut, we have had many inquiries from mobile operators, service providers, portals and device manufacturers who are sensing the urgency to provide a comparable service to MobileMe.”

Review: New MacBook puts style over affordability

Thursday, October 23rd, 2008

Plastic used to be the sexy material of the future. Now, it’s the cheap, ugly material of the past.

Just look at the effort Apple Inc. put into getting rid of plastic when designing its new $1,300 MacBook laptops, which went on sale last week. Apple now is machining the upper part of the chassis from a single block of aluminum, shaving it down to perhaps one-tenth of its original mass.

The result is a laptop with the stark elegance of a Modernist skyscraper, all glass and metal. The only things that are still plastic are the keys, the Apple logo on the lid, the bumpers on the bottom and some cladding on the hinge between the bottom and the display.

All that metal looks great, and it feels cool, in both senses of the word, to touch. But is this really what we want out of Apple?

The company is doing better than ever, with 9.5 percent of the U.S. PC market, according to Gartner Inc. Ten years ago, that figure was more like 3 percent. Not to knock Apple hardware, but I think the reason for this rally is mostly the company’s software, which is easy to use and well integrated with the hardware and Apple’s online services.

One of the best ways to get access to Apple’s OS X software has been its cheapest laptop, the MacBook. Chief Executive Steve Jobs has said it’s Apple’s best-selling computer. But at $1,100, it’s been nearly twice as expensive as a Windows laptop with comparable hardware. That’s a hefty premium to pay for good software.

Unfortunately, with the laptops it released last week, Apple chose to make the hardware slicker and more stylish, rather than push the price down. It brought some of the features of its even more expensive MacBook Pro line to the consumer line, rather than bringing the consumer line substantially closer to Windows PCs in price (though the older MacBook, now dubbed the “MacBook White,” got a $100 price cut. At $1,300, the cheapest of the new metal MacBooks is now $200 more expensive than the old plastic one.

For the price you do get some nifty new features, but some omissions in the MacBook package remain.

The new MacBook has the same 13.3-inch screen as the White, but it’s now backed by light-emitting diodes rather than fluorescent tubes. This means the screen reaches full brightness faster, and extends battery life a little bit.

The track pad is now huge and covered by glass, which gives it a pleasant, luxurious feel. The button has been eliminated to provide a larger tracking surface, but the bottom corners are spring-loaded, acting as buttons.

The graphics chip has been considerably upgraded, which helps with games and movie playback. I was able to play the fairly taxing 3-D spaceship game “Eve Online,” which has been difficult or impossible on a non-Pro MacBook before.

My favorite upgrade is the external battery indicator, which should be passed into law. Pressing a small button on the side of the laptop will light a row of eight diodes to tell you how much charge is left in the battery, even if the computer is off. Previous MacBooks had these indicators on the battery, so you had to turn the unit upside down to get a readout. A few Windows laptops have indicators on their batteries, but I don’t know of any that are as convenient to read as the new MacBook’s. Most laptops have no external indicators at all, so you have to turn them on to find out whether they need charging.

The new model weighs 4.5 pounds, half a pound less than the White, yet it has longer battery life. Apple says it’s good for five hours of “wireless productivity,” which presumably includes periods of inactivity. I got one hour and 50 minutes of life from the battery when I played movies and games nonstop at full screen brightness.

Like all Apple laptops, the MacBook lacks a slot for data cards from cameras, phones and music players. This isn’t a problem if you’re carrying the right cable to connect your camera via the USB port, but isn’t Apple supposed to be about easy, elegant computing?

Also, the MacBook has only two USB ports, and they’re both on the left side of the body. If you use a mouse with your right hand, the cable has to snake around.

Casting a glance at the competition from the Windows side: Hewlett-Packard Co.’s new dv3510nr has a screen that’s the same size, also backlit by LEDs and powered by a good graphics chip. It weighs the same as the MacBook, yet it has a larger hard drive, a backlit keyboard, a card reader and three USB ports, one of which one doubles as the kind of port needed for the newest, fastest external hard drives. Another port lets you connect the computer to a high-definition TV set with a standard cable. All for $100 less than the MacBook.

Of course, the HP computer is plastic, but from a utilitarian point of view, that isn’t a bad material for consumer electronics. It’s tough. It’s light. It’s easy to manufacture. High-end cameras used to have shells of brass and aluminum, but they were prone to denting, so the metal was phased out in favor of plastics that were tougher and gave a better grip. (In fairness to aluminum, it is much easier to recycle than plastic. Apple made several other environmentally conscious choices in designing the MacBook.)

The new MacBook is an excellent computer, but doesn’t really the change the advice I would give people who are looking for a new laptop. If you’re price-conscious but really want Apple software, get the $1,000 MacBook White. If you’re price-conscious but not set on Apple software, get a Windows laptop. If you aren’t price-conscious … hey, can you spare me a hundred bucks?
