Do you know why outdoor activity protects children from myopia?

Prof. Know Why answers for your general knowledge and awareness on: Do you know why outdoor activity protects children from myopia?

We all know that the more children are allowed to play outdoor sports, the better it is for their health in the growing days. But a recent study found that time spent outdoors even protects children against myopia.

The study has suggested that time spent in the open appears to protect children from near-sightedness, adding a new factor for a common condition that has long been blamed on extensive reading or genes.

Researchers at the University of Sydney, Australia, believe the intensity of outdoor light may be an important, but till now unrecognized, factor that influences the development of myopia, which usually begins during school years.

“Increasing outdoor activity may be a way to counter factors that might be contributing to myopia,” said Kathryn Rose, an ophthalmologist who led the study that involved more than 4,000 schoolchildren in Australia. It was published last week in the journal Ophthalmology.

The researchers found that 12-year-olds with the highest outdoor activity had the lowest rates of myopia, independent of the amount of reading or other near work they did. Myopia was most common in children with low levels of outdoor activity and high near work.

Long hours of indoor playtime or sports had no effect on myopia levels. “It appears to be the effect of intense light,” Rose said.

Myopic eyes are mildly elongated, front to back. The scientists believe that in response to light, the retina releases a chemical called dopamine and prevents eye elongation. The pupils also constrict in intense light, increasing the distance at which objects can be seen.

Near-sightedness has long been attributed to genetics. Children with parents who have myopia are at risk. “But we still can’t say whether it’s the effect of genes or whether the parents create an environment that promotes myopia,” Rose said.

“What has held out over the years is that children with strong scholastic achievements tend to have myopia. Our new study shows that children who do a lot of schoolwork and spend time outdoors appear protected.”

Independent studies in the US and Singapore appear to support these findings, she said.

The researchers have recommended more studies to try and establish the connection more firmly, and explore the mechanism of how exposure to daylight by means of outdoor activity, can prevent myopia.

Do you know why women love men with self-deprecating humor?

Miss Finder –The Journo, tries to find answers for your general knowledge and awareness on: Do you know why women love men with self-deprecating humor?

Hey guys, you would simply love this, because I’m going to give you yet another clue to win your woman’s heart. Well, being a woman myself, I always like honest men with good sense of humor. And, I’m not alone – confirms the latest study! So, what's the most effective way of winning a woman's heart? Well, it is by running yourself down! Yes, you read it right – women, in general, just love men with self-deprecating humor!

I’m sure you guys would find it hard to digest, but guys, this is now a proven fact. Researchers have carried out the two-year study which revealed that taking the mickey out of one's self, works better than just clever jokes which might be seen as boastful and put women off.

Lead researcher Gil Greengross said, “Many studies show that a sense of humor is sexually attractive, especially to women. But we've found that self-deprecating humor is the most attractive of all. It is a risky form of humor because it can draw attention to one's real faults thereby diminishing the self-deprecator's status in the eyes of others. But based on the idea that verbal humor evolved to function as a fitness indicator, self-deprecating humor can be an especially reliable indicator, not only of general intelligence and verbal creativity, but also moral virtues such as humility.”

In fact, in the study into the role of humor in seduction, the researchers have found that the type of humor used by Hugh Grant in the film Notting Hill, in which he attempts to charm Julia Roberts with the poor contents of his fridge - works the best.

But beware guys, before taking the plunge because the London researchers have also warned that the technique should not be attempted by those who are already unpopular as it could make “low-status individuals” appear “more pathetic” than they did before.

The study is to be published in the upcoming edition of the Journal of Evolutionary Psychology.

So, it’s not the smartest of the men with the most intelligent sense of humor that attract this present age women, instead, men with self-deprecating humor, make their way into their hearts. Are you listening, guys?

Do you know why banking online is unsafe?

Techie, the whiz kid, guides you through technology on: Do you know why banking online is unsafe?

Banking online may prove out to be time-saving and hassle-free, but have you ever thought about how unsafe it is? Many of you may argue to differ! But, actually banking online is riskier than assumed! Even a recent study by University of Michigan researchers confirmed this. The researchers found design flaws in 76 percent of the 214 U.S. financial institution websites that include top banks.

In fact, many banks make their online customers take risks with their passwords and other sensitive account information, leaving them open to internet frauds. The result is that even the most security-conscious Web surfers could also find themselves as victims of identity theft because they have been made habituated to ignore potential clues about whether the banking site they are visiting is real or a fake site served up by hackers.

Also, there are many banks that redirect users to third-party sites, where pop-ups like ‘secure login’ boxes crop up on insecure Web pages.

Moreover, the banks improperly use Social Security numbers or e-mail addresses — which an outsider that is an efficient hacker can figure out as default ‘user names’.

All of these banking practices put online banking customers at serious risk.

But actually, there are no basic problems with the bank websites' coding that could allow hackers to break in. Instead, it’s the design flaws of the bank sites that guide online banking customers to bad surfing habits.

One of the biggest problems is that even if the login boxes on banks' pages are properly secured (meaning they send and receive encrypted data through a technology known as Secure Sockets Layer or in short, SSL), the full page itself, in some cases, is usually not protected with the same technology — so it becomes more difficult to tell whether the site is real or fake. [SSL-equipped sites show a padlock icon in the address bar which ensure the secured encryption technology and assure that the site's owner is legitimate.]

Again, when users are not notified that they are being taken to another site (when a bank uses a partner site for online bill payments) — then it becomes hard to determine if the new site is trustworthy, because the online registration certificate carries a different company's name.

So even the most tech savvy of the online banking customers could fall victim to ‘phishing’ scams because they are supposed to enter personal information into the site that is not their bank's — and has not been clearly certified by the bank.

Here, the hackers could easily take advantage by sending them fake pages, dressed up like the bank's website. That site would then redirect to another site under the hacker's control, and users might not question the redirection.

Thus it is nearly quite impossible for the online banking customers to play safe. However, whatever little they can do is not click on the links sent in e-mails. At least, this way they can reduce the risks to an extent, if not completely avoid the hacking possibilities when doing online banking transactions.
