recently almost cell phone's product have the facility of "HSDPA"? what's that? almost everyone think about that...so i'm here to explain that to you..
HSDPA (High-Speed Downlink Packet Access) is a packet-based mobile telephony protocol used in 3G UMTS radio networks to increase data capacity and speed up transfer rates. HSDPA, which evolved from the WCDMA standard, provides download speeds at least five times faster than earlier versions of UMTS, allowing users of HSDPA networks a broader selection of video and music downloads. HSPDA specifies data transfer speeds of up to 14.4 Mbps per cell for downloads and 2 Mbps per cell for uploads. In practice, users are more likely to experience throughput speeds of 400-700 Kbps, with bursts of up to 1 Mbps.
In the United States, Cingular has a 3G/HSDPA network called BroadbandConnect. Cingular competes with Verizon Wireless and Sprint, which use a different 3G technology for broadband called EV-DO. One of the primary differences between HSDPA and EV-DO networks is that HSDPA allows mobile handsets to transmit voice and data simultaneously

Today we're going to pick up virtually any consumer magazine or open any Internet news web site and read about a frightening new threat: That radiation from cell phones is dangerous, it can causing brain tumors or other cancers. Most people have no knowledge of science other than what they hear on the news, so we have a whole population growing up with this understanding. Is the fear justified? Do cell phones have the potential to cause physical harm, or are they completely safe? Or, like so many other questions, is the truth somewhere in the middle?
Live cells can absorb signals from cellular telephones, states a new study by Prof. Roni Zeger of the Department of Biological Regulation at the Weizmann Institute of Science. The study examined how live cells respond to radiation emitted by mobile telephones. Although the study sheds no light on the debate regarding the effects on health of cellular communications, the researchers hope that the present study’s results will enable future researchers to address health issues.
The study examined both the intracellular and intercellular communications system. The Human Genome Project discovered that each cell has 200 switchboards which transfer incoming signals to the cell nucleus. The intracellular route is based on a chain of five to eight receptor proteins that forward the signal. The signals are mainly external physical stimuli, such as heat, or the identification of various molecules. In the latter case, the receptors transmit a message to the addresses within the cell.
According to Zeger, the study found that there are a number of extensions for each communications channel, and that each extension handles designated signals, which are sent to the address in the cell for expression. He adds that understanding these channels can help researchers understand disruptions in intracellular communications and help develop more effective treatments with few side effects for various diseases, including cancer.
The researchers claim that cellular telephone radiation might be one factor that activates the intracellular communications system, which enables living cells to respond in various ways to different radiation strengths and frequencies. The results cannot determine whether the use of cellular telephones carries any health risk. The study was conducted on cells exposed to radiation in the cellular frequency range for 45 minutes.

Do you know that brain is one of the important think in our body? our brain is the center of the human nervous system and is a highly complex organ. It gives us the power to think, plan, speak, imagine... It is truly an amazing organ. How if we never use it?? it will become useless...
Here i give you the list of game that will train your brain.
Brainist
A collection of free games and brain-related materials testing pattern-matching skills, memory, language and math skills, strategy, and more.
What’s unique: Sheer scope. Any and all things brainy and game-y can be found here, from number mnemonics to the most commonly used words in three languages to a speculative list of the smartest people ever.
Downsides: The site is a bit disorganized. You can’t track the gains you make in individual games.
Bonus: A classic IQ test like the one you might have taken as a teenager. Remember what you got then?
Summed up: All kinds of stuff to keep you entertained, though a bit scatterbrained. Check out the “Strategy Games” puzzle featuring six frogs sitting on seven rocks that must be hopped, one stone at a time, over each other’s heads. It’s marvelously frustrating.
Fit Brains
Comprehensive brain fitness site featuring 10 games plus a word challenge for team play. Tests fall into five cognitive categories: memory, language, concentration, logic/reasoning, and visuospatial skills. Sports a blog and a list of scientific advisers. Boasts “Guilt Free Fun!”
What’s unique: Complex, richly illustrated and thought-out games with different levels and basic story lines. For example, in “Hidden Masterpiece” you are a painting-repair specialist who sells reconstructed works of art at auction, testing visuospatial ability and concentration.
Downsides: After a seven-day free trial expires, the site is $9.95 a month or $79.95 a year. Some games may actually be too complex and time-consuming. In “Busy Bistro” you scan ingredients and cooking instructions, then try to remember the items by filling out a virtual grocery list. That’s just for starters: One round takes almost five minutes, and there are five more courses to follow.
Bonus: Get real recipes from “Busy Bistro,” like Crab and Swiss Melts.
Summed up: Very dynamic. Feels as if you are playing a console-based game at times. You can subscribe to track your progress and meet other Fit Brainers. Suitable for the committed brain athlete.
Games for the Brain
Enjoyable time killers, including standbys like checkers, sudoku, and chess, as well as original exercises like guessing (and then recalling) a country’s flag. Probes memory, pattern-matching abilities, spatial skills, and more.
What’s unique: Less hype—just lets you play. Simple scoring mechanism means you spend less time worrying about the clock and more solving the problem.
Downsides: Some of the games feel more, well, game-y than brainy.
Bonus: After entering a ticket number earned during your workout, you can see a prize image.
Summed up: A quick one-stop site for a dose of mental gymnastics. Lots of free games to choose from without any commitments, financial or otherwise. But you may not stick around for very long.
The Brainwaves Center
Mostly a puzzle-book shop and source for brain-gain advice; the site also features games testing language, mathematics, and memory skills.
What’s unique: New types of crosswords involving letters or numbers, timed for speed. Example: An “alphabetic” has only 26 spaces, one for each letter of the alphabet, which comes up just once per game.
Downsides: Games can be played only once before it’s all reruns. Superbasic visuals are mostly black-and-white.
Bonus: Cool crosswords!
Summed up: Although the games are neat, getting to play them only once is a bummer.
Brain Arena
Billed as “massive multiplayer online brain-training,” the Web site hosts contests challenging players’ visuospatial skills, arithmetic ability, and reaction time.
What’s unique: Competition among thousands of mind-gamers trying to beat one another’s scores. Winners crowned every 24 hours.
Downsides: Repetitive games that reward your quickness to click a mouse as much as your acumen. Almost 80,000 people have joined the site, but it still feels junior varsity: Some tasks, such as a tiered addition problem, are either poorly explained or not explained at all.
Bonus: Cheeky names for players’ rankings: You start off as a puny Habilis, work your way up to Sapiens—and if you keep at it, achieve Cibernetis status.
Summed up: The site feels a bit like it’s under development, but the league-play aspect is intriguing—especially for those with a competitive streak.
Lumosity
A cleanly constructed site that is serious about representing the science of brain games, referencing studies and neuroscientists who support this approach to brain fitness. Tests memory, processing speed, attention, and cognitive control, which is basically impulse restraint.
What’s unique: Lets you set up a training program with regimented sessions and claims to offer a full workout in only 10 minutes.
Downsides: Just as expensive as Fit Brains but less visually appealing. Some games feel more clinical than creative.
Bonus: Waddling, animated penguinlike characters are cute.
Summed up: Solid, absorbing exercises that strike a good balance between basic playability and complexity, though a bit blah at times. After signing up, the Web site tracks your progress and tells you what to do. After all, if you’re doing neuro-workouts, you might as well get a personal trainer. (Full disclosure: DISCOVER links to Lumosity games from the sidebar on certain pages.)

Two years ago a team of engineers amazed the world (Harry Potter fans in particular) by developing the technology needed to make an invisibility cloak. Now researchers are creating laboratory-engineered wonder materials that can conceal objects from almost anything that travels as a wave. That includes light and sound and—at the subatomic level—matter itself. And lest you think that cloaking applies only to the intangible world, 2008 even brought a plan for using cloaking techniques to protect shorelines from giant incoming waves.
Engineer Xiang Zhang, whose University of California at Berkeley lab is behind much of this work, says, “We can design materials that have properties that never exist in nature.”
These engineered substances, known as metamaterials, get their unusual properties from their size and shape, not their chemistry. Because of the way they are composed, they can shuffle waves—be they of light, sound, or water—away from an object. To cloak something, concentric rings of the metamaterial are placed around the object to be concealed. Tiny structures—like loops or cylinders—within the rings divert the incoming waves around the object, preventing both reflection and absorption. The waves meet up again on the other side, appearing just as they would if nothing were there.
The first invisibility cloak [subscription required], designed by engineers at Duke University and Imperial College London, worked for only a narrow band of microwaves. Xiang and his colleagues created metamaterials that can bend visible light backward—a much greater challenge because visible light waves are so small, under 700 nanometers wide. That meant the engineers had to devise cloaking components only tens of nanometers apart.
Xiang’s group also cleared another design hurdle. A competing team had devised a metamaterial to cloak visible light, but it was just one atom thick, too flimsy to deflect anything more than a single sheet of incoming light. Xiang’s new metamaterials have heft.
Last March José Sánchez-Dehesa and Daniel Torrent, physicists at the Polytechnic University of Valencia in Spain, presented a design that would allow a cloaked submarine to hide from sonar. This technology could also allow an orchestra patron sitting behind a cloaked column to hear music as clearly as one in an unobstructed spot.
In September French and British physicists presented a plan for using metamaterials to shield shorelines from the impact of massive waves. Their proposed device[subscription required] would look like a scaled-up acoustic cloak: concentric circles of posts surrounding a hidden object. When a wave hits them, the posts would redirect it around the object without ever breaking the wave. The researchers say that such a device could be used to protect isolated spots in the ocean—like drilling platforms or low-lying islands—or coastal regions vulnerable to tsunamis.
But the weirdest extension of the cloaking concept is undoubtedly the “matter” cloak described this past year by Shuang Zhang, a postdoctoral associate in Xiang’s lab. Subatomic particles like electrons travel as waves, and Shuang showed how metamaterials could be used to divert an atomic wave the same way the invisibility cloak re¬directs a light wave. If such a device could be scaled up to the human-size world (far from certain, alas), it might be able to steer a bullet around a bulletproof cloak.
