A computer with a wireless Internet connection hurts sperm, but not because the machine can heat up your lap, a new study suggests.

“Wi-fi radiation kills, harmed sperm — Care your Health from Technology”

After four hours of exposure, one-quarter of the sperm were no longer swimming — Reuters reported. In comparison, 14 percent of sperm cells that had been kept at the same temperature but not exposed to wi-fi were no longer swimming. What's more, DNA damage was more common in the wi-fi sperm than in the "control" sperm.

In a control test — with the sperm kept away from WiFi emissions, but at the same under-laptop temperature — 14% of the sperm died within four hours, and 3% showed DNA damage. When placed underneath a laptop for four hours, 25% of the sperm died and 9% showed DNA damage. The important finding here is that WiFi electromagnetic (EM) radiation damaged the sperm — almost every other study has focused on increased temperature (which also damages sperm, incidentally).

Do not dispose empty Beer / soda Can they contribute WiFi signals.

A piece of Aluminum foil (Foil, a quite thin sheet of metal, usually manufactured with a rolling mill machine) is probably the easiest and cheapest way to boost your home Wi-Fi signal.

A device enabled with Wi-Fi, such as a personal computer, video game console, smartphone, or digital audio player, can connect to the Internet via a wireless network access point. An access point (or hotspot) has a range of about 20 meters (65 ft) indoors and a greater range outdoors.

Here the tricks, just position the foil behind the antenna of your wireless router and the curved foil will then direct the Wi-Fi signals in your preferred direction thus boosting the overall signal strength.

Increase Wi-Fi network with a Beer /Soda Can

Toshiba is announced the world's first WiFi-enabled SD memory card, the company announced today at the IFA consumer technology show in Berlin.

The new FlashAir card looks outwardly like a standard SDHC memory card and weighs in at a measly 2g. It will initially be available in a capacity of 8GB

Being able to send images and video straight from camera to social media sites or computer seems to us the next logical step in camera memory. Eye-Fi already make use of some very similar technology which sees its cards being able to upload pictures to websites like Flickr.

The cards will be compatible with the 802.11n wireless standard, and backwards-compatible with the b and g variants. Security is provided by WEP, TKIP and AES encryption (WPA and WPA2).

Toshiba is currently seeking Wi-Fi certification for FlashAir in Japan, North America and Europe, and says the first FlashAir cards will go on sale in February 2012. via thinq
