Despite your best efforts, it is possible that your smartphone will get wet in the rain. So what do you do? Here are some handy tips

the first step is simple: Don’t panic! Relax, take a deep breath, it’s not the end of the world.

So, switch off your phone and take the battery out of it, along with the SIM card and the memory card. Remove the back cover too. Any other removable items, like a loop or a screen cover? Take that off too.

Shake it, baby! As silly as it sounds, give your phone a vigorous shake to get rid of as much water as you can.
Use a soft 2-ply or 3-ply tissue to wipe the phone dry. Make sure you don’t use a rugged or coarse tissue. Also, be very gentle when wiping parts around open circuitry.

Go to the nearest air conditioner and hold the phone at its vent to dry it out. Do not use a hair dryer or leave your phone under a fan. Hot air as well as dust can be disastrous for your phone, especially when wet.
Grab a large bowl or a pot and fill it up with uncooked rice. Make sure the rice is clean, though, because you don’t want dirt particles going into your phone. Carefully bury your phone in this rice—front side up—and seal the bowl. Rice helps absorb moisture, so this will dry out your phone better than any other method. Leave your phone in the rice bowl for at least 24 hours, but the longer you can keep it, the better. An alternative to rice is packets of silica gel, but it is a tad expensive and not as easy to get your hands on either.

Once you retrieve the phone the next day, grab a cotton ear bud and dip it in some alcohol. Gently dab the circuitry to dry out the remnants of water. Use a cotton bud only a few times and then switch to a new one.
At this point, your phone is ready to be switched on. But use your judgment here. If you still think it seems to retain a little water, then repeat the rice bowl solution until you are satisfied that there’s no moisture left.
When you are ready, put just the battery into the phone and switch it on. If everything is working fine, then install the SIM card and memory card into your handset and get back to business.

The contact lens that can receive your text messages

New technology that will allow information, such as text messages from a mobile phone, to be projected onto a contact lens worn in the human eye has been developed by Belgian researchers.

Scientists have developed a new technology that allows electronic messages sent from mobile phones to be directly projected on to contact lens placed in the recipient’s eyes.
The spherical curved LCD display, created by Belgium researchers at Ghent University, handle projected images using wireless technology.
The lens’ capability were demonstrated by scientists who showed a dollar sign being projected on to the lens


Must Must Share…..!! You can reduce the radiation risks posed by cellphone



You can reduce the radiation risks posed by cellphones if you religiously avoid talking on your mobile for more than six minutes. But since it can be an unrealistic target for many, using a speakerphone or headset and keeping the mobile at least a foot away from the body is the safest option, experts say.

Most importantly, reduce the number of calls from cellphones and use the SMS option instead, or landlines whenever possible. Above all, don’t forget to check the specific absorption rate (SAR) while buying a phone, it should be strictly 1.6 watt/kg and not beyond it, suggest telecommunication officials.

If at all you are exposed to radiation from cell towers, or if your residence or office is within 1km from a TV tower or within 500 meters of an FM tower, then growing plants or trees with more water content, or putting water curtains on windows or galleries are other ways to divert radiation.

But the best option is to complain against such a tower. An inter-ministerial committee of experts formed by the ministry of communications and information technology to study the hazards posed by cellphones and towers has already highlighted that radiation from cellphones and towers poses serious health risks, including loss of memory, lack of concentration, disturbance in digestive system and sleep disorders.

In June last year, the WHO and International Agency for Research on Cancer (IARC) classified radiofrequency electromagnetic fields as Group 2B agents that could “possibly be carcinogenic to humans,” or in simpler words cause brain cancer. Globally, researches are still trying to gauge health hazards caused by prolonged use of cellphones.

Senior consultant radiation oncologist Dr Anusheel Munshi said while more data is awaited, preliminary findings could be strong enough for people to think prevention. “So far, prolonged usage for at least a decade has been linked with brain tumours. It is believed that constant exposure of certain regions of the brain to electromagnetic radiation is to blame for tumours,” he said. Munshi also suggested that plug-in ear devices should be used more often and even texting could be used more frequently than talking.

A paediatrician from civic-run Sion Hospital said cell phone usage should be kept to minimum for children. “The damages could be more in case of children as their skull bones are thinner than adults and therefore electromagnetic radiation could penetrate deeper,” the doctor said.

R K Bhatnagar, advisor (technology ) to the department of telecommunications, said even corrective action such as reducing the frequency of the antennas, changing their position and direction can also help reduce the effects of radiation on humans. “Re-engineering is possible in most cases, which can give lot of relief but in extreme cases removing them can be the final option,” he said.
