Scientist Infected With Computer Virus A British scientist has become the first human to be infected with a computer virus

Saturday, March 22, 2014

A British scientist has become the first human to be infected with a computer virus.
Dr Mark Gasson, a cybernetics expert at the University of Reading, has had a computer chip implanted in his hand.
The chip is programmed to open security doors to his lab - and ensure only he is able to switch on and use his mobile phone.
But Dr Gasson deliberately infected the chip with a computer virus, which was then automatically transmitted to the lab security system.
"Once the system is infected, anybody accessing the building with their passcard would be infected too," he told Sky News.
The virus on his chip is benign. But malicious computer code could give criminals access to a building.
Dr Gasson says his experiment also exposes the vulnerability of chips now routinely implanted in patients.

Heart pacemakers contain mini-computers that control the heartbeat, and communicate with doctors via a special reader held against the skin.
But if a virus was transmitted to the device which stopped it working properly, the consequences for the patient could be fatal.
"The devices will have to start to use security encryption," said Dr Gasson.
"Medical devices should have some kind of password protection as well. Theyre basic security precautions. Its surprising these devices dont have them already."

9 Signs weight has dropped

Thursday, March 6, 2014

9 Signs weight has dropped - Months of dieting and regular exercise makes you wonder whether you have achieved the desired weight or not. 9 Fortunately this sign tells you whether you ve lost weight or not.

1. Your clothes feels right

When you wear clothes, you feel fit and comfortable. You also do not need to cover the fat with a jacket or cardigan.

2. You can reuse your old clothes

Finally you can re- wear your old clothes that are still good but you had to keep it in the closet because it does not fit anymore.

3. Skin feels slack

Had experienced skin stretches when your weight increases. However, if you later find that the skin feels loose, it is possible that your weight has gone down.

4. You have more energy

Increased energy gained from your weight loss program through a good diet and regular exercise.

5. You feel excited

The ideal body weight will indirectly affect your mood changes. You become happier, confident, and excited.

6. Increase your libido

Another sign that indicates that you have experienced your weight loss is your libido or sexual desire increases. This happens because of mood changes that occur.

7. Structure and proportions of your body improves

That accumulate in the body fat lost will impact the physical appearance. Structure and proportions of your body is also recovering.

8. You can sleep soundly

Healthy lifestyle that you have been doing while undergoing a weight loss program will affect the quality of your sleep. Sleep quality to be good and you can sleep soundly.

9. Praised the people around you

Physical changes that occur when the weight has dropped to reap the praise of those around you. The praise will make you become happier because you have had successful weight loss program.

Well ladies, if you feel that you have 9 marks above the weight you have reached the ideal weight. But you also should not be complacent. Be sure to keep living a healthy lifestyle just like when you go about your weight loss program so that your weight remains stable and the body becomes more fit.

Resveratrol can still be used in the body after it has been metabolized

Tuesday, February 25, 2014



A chemical found in red wine remains effective at fighting cancer even after the bodys metabolism has converted it into other compounds.

This is an important finding in a new paper published in the journal Science Translational Medicine by Cancer Research UK-funded researchers at the University of Leicesters Department of Cancer Studies and Molecular Medicine.

The paper reveals that resveratrol – a compound extracted from the skins of red grapes – is not rendered ineffective once it is metabolised by the body.

This is an important development, as resveratrol is metabolised very quickly – and it had previously been thought that levels of the extracted chemical drop too quickly to make it usable in clinical trials.

The new research shows that the chemical can still be taken into cells after it has been metabolised into resveratrol sulfates.

Enzymes within cells are then able to break it down into resveratrol again – meaning that levels of resveratrol in the cells are higher than was previously thought.

In fact, the results appear to show resveratrol may be more effective once it has been generated from resveratrol sulfate than it is if it has never been metabolised because the concentrations achieved are higher.

The team, led by University of Leicester translational cancer research expert Professor Karen Brown, administered resveratrol sulfate to mice models.

They were subsequently able to detect free resveratrol in plasma and a variety of tissues in the mice.

This is the first direct sign that resveratrol can be formed from resveratrol sulfate in live animals, and the researchers think it may help to show how resveratrol is able to have beneficial effects in animals.

The study also showed that resveratrol generated from resveratrol sulfate is able to slow the growth of cancer cells by causing them to digest their own internal constituents and stopping them from dividing.

Professor Karen Brown said: "There is a lot of strong evidence from laboratory models that resveratrol can do a whole host of beneficial things – from protecting against a variety of cancers and heart disease to extending lifespan.

"It has been known for many years that resveratrol is rapidly converted to sulfate and glucuronide metabolites in humans and animals – meaning the plasma concentrations of resveratrol itself quickly become very low after administration.

"It has always been difficult to understand how resveratrol is able to have activity in animal models when the concentrations present are so low, and it has made some people skeptical about whether it might have any effects in humans.

"Researchers have hypothesized for a long time that resveratrol might be regenerated from its major metabolites in whole animals but it has never been proven.

"Our study was the first to show that resveratrol can be regenerated from sulfate metabolites in cells and that this resveratrol can then have biological activity that could be useful in a wide variety of diseases in humans.

"Importantly, we did all our work with clinically achievable concentrations so we are hopeful that our findings will translate to humans.

"Overall, I think our findings are very encouraging for all types of medical research on resveratrol. They help to justify future clinical trials where, previously, it may have been difficult to argue that resveratrol can be useful in humans because of the low detectable concentrations.

"There is considerable commercial interest in developing new forms of resveratrol that can resist or overcome the issue of rapid metabolism. Our results suggest such products may not actually be necessary to deliver biologically active doses of resveratrol to people."
