Nokia to announce a new QWERTY phone this Wednesday

Nokia has kept the QWERTY phone format alive in its Asha range and even though recent models have gone with the full touchscreen trend, the company will be announcing a new QWERTY-packing phone this Wednesday.

A teaser post on Nokia Conversations went up, promising "something new" from an announcement taking place at 7am GMT this Wednesday.After that there will be a Q&A session with Neil Broadley from Nokia’s Mobile Phone team (the team behind feature phones) and a "special guest".

Other than a yellow color options and a seemingly thin bezel, there’s nothing we know about the upcoming device. There should be more teasers until Wednesday, maybe even a leak so stay tuned!

Acer teases arm-packing notebook in non sequitur Star Trek spot

In a dual-marketing campaign that's admittedly cooler thanHuawei's duet with the Jonas Brothers, Acer is advertising its Windows 8 notebooks alongside the forthcoming Star Trek: Into Darkness feature film.

The "Explore Beyond Limits" spots awkwardly splice scenes from the film with glamor shots of Acer products, but today's video teases a never before seen notebook that definitely piques our interest.

The gadget appears to be able to transform from a laptop into desktop-ish form thanks to an arm that slides out from the back of the screen, extending it beyond typical notebook display height.

The unnamed device looks quite thick when it's in regular laptop form, but we won't know what the actual dimensions are until it's announced May 3.

It doesn't make sense...

There are no perceivable tie-ins between the film and the notebook, but that never stopped two brands from co-promoting before, has it?

Into Darkness hits theaters May 17, so look for more shared promos between the Trekkies and Acer.

Is this the first 8-inch Windows 8 tablet?

Acer may soon offer up the first 8-inch Windows 8 tablet, a device dubbed the Iconia W3.

This is according to Minimachines.net (Google translated) which posted an army of images purportedly of the unannounced device.

The Iconia W3 measure 8-inches from corner to corner and is said to come with a dual-core Atom Z2760 processor with hyper-threading. Clocked at 1.8GHz, Minimachine and we agree that it's not a "monster" when it comes to performance, but hey, size is sort of the selling point here.

There's also apparently 2GB of RAM, a dual camera and speaker set-up and spaces for perhaps microUSB and microSDHC.

What 8-inches gets you

Microsoft last week made clear that smaller touch-enabled devices are indeed on the way from its OEMs, and Acer may be well on its way to making good on that promise.

While there's a greater than good chance Microsoft is developing its own smaller version of the Surfacetablet, Acer's leak has anything from Microsoft beat out of the gate.

Minimachines states the slate will be out by the time the school year starts again (mid-August-ish), which while it makes a lot of sense doesn't have official backing, so we can't take it (or any of the leak's information) as gospel.

As you can see from the photos, the Iconia W3 will have the option to sit inside a keyboard, which one can type on but not use for syncing or charging.

Are wireless signals really dangerous?

While we are surrounded by radio waves emitted by the Cosmos, we have only known about them since the 1890s, when wireless transmission was first demonstrated.

However, It wasn't until the late 1980s, with the advent of the first mobile phones, that radio transmitters first started entering the home, and even then, it took until the early-to-mid 1990s before mobile phones became commonplace. The mid-1990s also saw the first consumer use of wireless networks, and just as with phones, only took a few years to become mass-market products.

Look around a modern home and you will see that we are now surrounded by devices which emit radio waves, from our mobile phones to laptops and tablets, wireless routers, baby monitors, cordless phones, wireless games console controllers, some TV and Hi-Fi remotes (although most use Infra Red), wireless burglar alarm systems, Bluetooth headsets, keyboards and mice, wireless weather stations and more.

So does all this electromagnetic radiation pose any sort of health risk to us? This is a question that many scientists have been struggling to answer and it seems that trying to get a definitive answer is not easy.

There's no doubt that Radio Frequency (RF) energy can be powerful and dangerous. Microwaves ovens use radio waves to heat food, which is why they need proper shielding to be safe. High-powered radio transmitters, such as those used on military vehicles, have warnings to keep away from the antenna, because coming into contact with it while the radio is transmitting can give you a nasty burn (known as RF burn).

Microwave ovens use a frequency around 2,450MHz (2.45GHz), Bluetooth 2,400MHz to 2,408MHz, and Wireless LAN uses 2,412MHz to 2,484MHz. Other devices, such as baby monitors and burglar alarms tend to use FM frequencies (e.g. 433MHz).

Mobile phones vary from country to country and cover a wide spectrum of frequencies although the most popular are 850MHz, 900MHz, 1,800MHz and 1,900Mhz. While any radio wave with a frequency between 300Mhz and 300GHz is classed as a microwave, it doesn't mean that they all have the same characteristics.

How bad are microwaves?

Microwave ovens are able to heat food for three reasons; the waves are highly focused, the metal box of the oven prevents the waves from dispersing, therefore they are fully absorbed by whatever is in the oven and thirdly, the emission power is very high (up to 1,000w). In contrast, a Bluetooth headset, wireless land or mobile phone's RF emissions are unfocused and unconstrained, while the emission power is much lower.

Bluetooth devices range from 1mW to 100mW, Wireless LANs between 32mW and 200mW, while 3G mobile phones have a maximum power output of 2 Watts, but will typically be operating at around 500mW, although the first analogue phones had a peak output of 3.6W.

From this it's fairly obvious that the amount of RF energy emitted by most devices, is incredibly low. However, any device which operates near the same frequencies as a microwave oven, i.e. around the 2GHz mark, could potentially generate some of the same effects, including localised heating of tissue. It is this heating effect which has led some to believe that microwave frequency radio waves are detrimental to health.

What about phones?

In 2011 the International Agency for Research on Cancer (IARC) classified mobile phones as possibly carcinogenic, although the World Health Organisation has said that "to date, no adverse health effects have been established as being caused by mobile phone use". A number of studies have been carried out, but as mobile phone use has only been widespread for around 15 years or so, so far, there has no direct evidence of a link between mobile phone use and cancer.

One of the largest studies was carried out in Denmark and involved around 420,000 people, who had been using mobile phones for 21 years (1982 to 1995). Despite the fact that the users would have been using the higher powered analogue phones, as well as lower-powered digital phones, the researchers concluded that there was no evidence for an association between tumour risk and mobile phone use, even in long-term users.

So what about other health risks? There have been many stories which claim that RF exposure can interfere with sleep patterns. Research here is contradictory, with one Finnish study showing no ill effects, others have found that pulsed RF can have an effect on the brain. Some people even believe that being soaked in radio waves has other effects upon the body, such as fatigue, lack of concentration, headaches or memory issues, and this is known as Electromagnetic Hypersensitivity.

However, in 2010, a review of 46 studies into electromagnetic sensitivity found that there was no robust evidence for the existence of electromagnetic hypersensitivity. In double-blind tests, those who claim to suffer from hypersensitivity were unable to conclusively determine whether a RF emitting device is on or off.

Reducing exposure

While RF emission power levels are regulated by national legislation, some manufacturers, it seems, take extra steps to reduce your exposure. It has been discovered that in Apple's latest iPad, there is apparently a proximity sensor, which will reduce the power of the device's 3G radio, when it detects a solid object (such as any part of your body) within 10mm top of the screen. However, according to Pong Research, it's not just human tissue which triggers the sensor, most iPad cases do as well.

Pong does have a vested interest in these claims, however, as it markets a range of cases which it claims not only stop the proximity sensor of the iPad activating, when fitted with a case, but which also direct the RF energy of your mobile device away from your head., using a passive, coupled antenna. Unfortunately these are claims we can't verify, as we simply don't have access to the necessary testing equipment, however, Wired has an extensive writeup on Pong's claims and comes to the conclusion that yes, these cases do in fact live up to their claims, when tested in a compliance testing lab.

One of the points Pong makes is that most SAR (Specific Absorption Rate – a measure of how much RF energy is absorbed by the human body) tests are done on models of adults heads. The argument is that a child's head, especially one under the age of 10, has a much thinner skull than an adult and the brain is more vulnerable to the effects of RF radiation.

This is a fair point and while some more recent tests have been conducted using head models based on MRI scans of a child's head, most studies have been based on adults. Studies that have used models of a child's head have shown increased absorption of microwave frequency radio waves.

So, the question is, should you be worried about the emissions your wireless devices are giving off? This is the billion-dollar question and to our minds, still hasn't been answered. So far the evidence would suggest that adult users are at very low risk, but more research needs to be done. For children, the risks would certainly appear to be higher. Trying to police your child's phone use is probably impossible, so reducing exposure seems like the next best option.

Using a Bluetooth headset is certainly one way to reduce the amount of RF radiation your head is exposed to from your phone, although they are not the easiest things to use and far too easy to misplace. Using a case that directs radiation away from the head would seem to be the next best option and Pong's cases would certainly seem to fit the bill.
