radiation threaten to Japanese rice crops

At least 18 of the prefectural governments most acutely affected by radioactive fallout from the Fukushima Daiichi nuclear disaster last spring are running tests to gauge the safety of local food supplies. The areas produce nearly half of the nation鈥檚 rice crops, Reuters reports.

鈥淐ontinuous consumption of rice containing cesium above the government-imposed limit of 500 becquerels per kg over a year will result in internal radiation exposure above 5 millisieverts, one of the more conservative standards for radiation exposure set by the International Commission on Radiological Protection,鈥 the Japanese health ministry said in a statement.

Crops will be checked both before and after harvesting. Radiation fears were swelling in June as citizen journalists and scientists created a map alleging widespread contamination throughout eastern and northern Japan – as far as 100 miles away from ground zero.

Japanese authorities suspended beef shipments from the Fukushima region last month. Rice straw cows absorbed unsafe levels of cesium through their feed stocks. Crops such as rice and grains quickly absorb radiation, potentially making dairy products and produce for human consumption.

photovoltaic power without sunlight

With heat, tungsten, and a silicon cell, MIT researchers have been developing a different way to get power from photovoltaics without sunlight.

Photovoltaic cells work best with light hitting them at certain wavelengths. Ultra-violet and infrared waves, for instance, can be tough for semiconductors to absorb in order to generate electricity. But engineers at MIT have designed a system that converts heat into specific light wavelengths, custom fit for a solar cell. And possibly, custom fit for miniature electronics as well.

Such thermo-photovoltaic systems have been around for a while, but they haven鈥檛 performed as efficiently as the silicon chip 鈥渕icro-reactors鈥 described recently in the journal Physical Review A. Etching a pattern of nanoscopic pits and ridges into a bit of tungsten, the researchers created a thermal material that can partner up with a photovoltaic cell to absorb more light radiation. The tungsten heats up and glows, with the design on its surface controlling the way light behaves. According to the study, the sculpted pits act resonators, emitting light with wavelengths best suited for uptake by the PV cell.

Need a recharge? Just add heat. This could come from the sun but doesn鈥檛 have to. For the study, the engineering team used the hydrocarbon butane. So in the future, butane might power more things in your pocket than your cigarette lighter. They also developed a device that could draw heat from a decaying radioisotope. With such a heat source, years could pass between recharges. The researchers have long, dark space missions in mind.

solar services to electric vehicle chargers

SolarCity, a solar integration and financing company that is steadily pushing its services across the United States and has some pretty impressive buddies including Google, is adding solar-powered electric vehicle chargers to its bag of tricks.

The initiative has two parts. First, the company has teamed with electric charger maker ClipperCreek to install its technology at the 24 operations centers that SolarCity manages. Those operations centers support the company鈥檚 installation activities in Arizona, California, Colorado, Hawaii, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Texas and Washington, D.C.

ClipperCreek鈥檚 technology is a 240-volt Level II electric vehicle charger, priced at $1,500. It is compatible with the Chevrolet Volt, Ford Transit Connect, Nissan Leaf, Tesla Roadster and SAE-compatible hybrid vehicles (including some that are in the new car pipeline). Level II chargers work faster than a 120-volt wall outlet, roughly five times faster.

SolarCity also works with Toyota as the distributor of the electric vehicles chargers for Toyota Tsusho.

Aside from being a solar installer, SolarCity provides energy-efficiency services for its residential and commercial customers, so this is a logical extension of its services.

If you can鈥檛 stomach the aesthetic or financial impact of investing in solar energy at your home or business, this might be one way to test things out in a smaller way.

smartphone without the phone and tablet without the screen

Sitting somewhere between a tablet and a smartphone – minus the phone – is the ICE Smart Media Player from Latte Communications. With a 5-inch display and running Android 2.3 (Gingerbread), the device joins the netherworld between smartphones and larger screen tablets currently occupied by the Dell Streak. But unlike the Streak, the ICE Smart doesn’t include have the ability to make calls, making it more like an oversized Android version of the iPod touch.

Latte are touting their device as the “first Android based 5-inch full HD media player in the market.” Since the 5-inch display market isn’t exactly overcrowded we’d be inclined to believe them. Powered by an 800 MHz ARM 11 processor with a built-in 3D accelerator the device boasts Full HD 1080p video playback. Video can be viewed on the 800 x 480 pixel resistive touchscreen display, which supports dual touch, or mirrored on a HDTV via the mini HDMI out port.

There’s 8GB of onboard storage, with a micro SD card slot providing up to an extra 32GB of storage space if desired. The device sports 802.11 b/g as well as a g-sensor, built-in speaker and mic.

why we can鈥檛 get smarter

Here鈥檚 an interesting fact: Smart people have faster impulses in the brain than less intelligent people. That鈥檚 all according to one Cambridge professor by the name of Ed Bullmore. But as far as getting any smarter, tough luck. British scientists made a convincing case for why our brains have reached full capacity: Human brains would consume too much energy.

There鈥檚 a chance the human brain could start to conserve energy and bring us back towards the size of the noggins of our Neanderthal ancestors, according to The DailyMail. The researchers took into account the structure of the brain and figured out how much energy brain cells consume.

Mathematically speaking, the brain is an energy hog. It鈥檚 physically smaller than the rest of the human body, yet it consumes 20 percent of our energy. Energy is needed to fire electrical impulses so neurons can communicate with each other and also maintain the health of the cells to keep the tissues in the brain alive.

To get any smarter, the brain would need extra energy and oxygen, something all the coffee and Red Bull in the world probably can鈥檛 provide. Also, in the DailyMail story, the researchers say there鈥檚 a link between how connected different brain areas are and IQ. However, there isn鈥檛 enough energy to keep up with any increase in brain power.

Skype for iPad now available

This new Skype for iPad software has been something I have been wanting for a long time and thankfully brings video calling support via 3G and WiFi, as well as IM and voice calls. You can even make calls from your iPad to landlines and mobile phones using your Skype Credit. You can use either the front or back camera on the iPad 2 while Skype also works on the first generation iPad device. I loaned my iPad to a coworker today so he could use it with Keynote to give a presentation to a client (right on the iPad without a projector) during a dinner meeting so I won鈥檛 be able to try out the new Skype client until tomorrow.

Skype now has full video, call, and IM clients for the iPad, iPhone, and Android devices so it is now becoming easier to make video calls and with a standard service like Skype I think this is what we need to see this capability grow in popularity.

UPDATE: Skype had the iPad version pulled off the App Store and tweeted that it was posted prematurely. Hopefully it goes live again soon, for real this time.

UPDATE 2: It鈥檚 now back in the App Store so go get it now and give it a whirl on your iPad.

Social media is useful to businesses

Social media is useful to businesses because it offers what Shel Israel and Robert Scoble call 鈥渘aked conversations鈥 you can listen-in to customers when previously you couldn鈥檛 except through expensive market research focus groups.

But if corporations try to turn social media into a corporate sales or marketing channel then they risk losing the naked conversations, and the insight into customer behaviors 鈥 it鈥檚 no longer social media but some form of mutant corporate media.

I like the approach of the Altimeter Group, a business consulting firm founded by Charlene Li, which emphasizes listening. [Please see: Altimeter Group and the syndrome of the deaf corporation...]

Listening is a rare commodity in today鈥檚 world where interruptions come every few seconds and distractions are just a click away.

Listening is important to conversations, yet most people wait to speak rather than listen to what鈥檚 being said. (There are lessons here for businesses.)

Listening to social media also preserves the authenticity of what鈥檚 being said. If people have to look over their shoulder to watch what they say or share, then it will be harder to be authentic. And if their social networks become swamped with corporate media then that will change the original nature of their communities 鈥 their involvement will be lessened.

But there is a very strong push by the legions of self-styled social media experts to persuade corporations to turn social media into a corporate sales channel 鈥 with the warning that if they don鈥檛 do it their competitors will. And their competitors certainly will.

Which means social media as we know it will be changed as corporations rush to co-opt it to their agenda.

Yes, some corporations are using a light touch but the pressure is on to do more, far more involvement, more engagement, and to intercept conversations. This will damage the fundamental integrity of social media as we know it.

Corporations will try to engage too strongly, or in inappropriate ways; they will corrupt the very influencers that they covet through poorly thought-out marketing schemes; and social media will blend into a mutant form of corporate media.

Social media will survive but not in the same forms or in the same places that we find it today. People will react by moving their conversations into less visible corners of the Internet, into private groups/networks that offer a far higher quality of social interaction, more intimate, and more importantly 鈥 sheltered from the ever vigilant and prying corporate eye.

Apple become top smartphone vendor in the world

Even though it only releases one smartphone per year and relatively only has one model to speak of, Apple has found itself at the top of the list of the world鈥檚 leading smartphone vendors.

According to the latest survey from Strategy Analytics, a global independent research firm based in Boston, Apple is the became the 鈥渓argest smartphone vendor in terms of revenue and profits鈥 during the second quarter of 2011.

Apple recently topped another list as well as it was named the number one maker for smartphones in June within the United States, according to Nielsen. Steve Jobs & Co. bested the Android set (mostly Motorola, Samsung and HTC) by securing 28 percent of the domestic market share. It also doesn鈥檛 hurt that approximately 35 percent of consumers plan to buy the iPhone 5 when it is released – even though Apple hasn鈥檛 said a single word about the device ever.

But as Apple rose, who fell? At least one of the answers, unfortunately for that company, is rather obvious: Nokia.

Samsung also rose in the shadow of Apple to the number two spot with very impressive growth figures, as did the 鈥淥thers.鈥

Overall smartphone shipments grew by 76 percent worldwide to 110 million units mailed out during Q2 2011, which Strategy Analytics described as a positive 鈥渞ecord.鈥

What to buy your kid for college

1: Netbook: Samsung NF210-A02
The Samsung NF210 (A02) could well be considered the ultimate non-MacBook student netbook. Unlike the MacBook Air, which features later in this deck, it has a matte screen so you get little glare or reflection, it sports a decent dual-core Atom processor and a smooth feeling keyboard which is a pleasure to type on.

Not only this, but it’s relatively cheap compared to a fully-fledged laptop — and definitely for the more frugal student who cannot afford a MacBook. It’s light, runs for hours on the battery, and has a brilliant screen for viewing videos and text. Not only that, with wireless-n you can stream videos and download wirelessly at extremely fast speeds.
2: Online content: Netflix gift subscription
Netflix is, without doubt, one of the most comprehensive collection of online content, from films to television episodes, available legally on the web. Since colleges and universities are cracking down heavily on internet piracy, it is better to stay on the right side of the law.

While Hulu, it’s nearest competitor, is all about television, it’s better for finding the more quirky in television and films, rather than the popular content of the day. Netflix works off a subscription, so you can pay less than $10 a month, or pay around $100 for the full year. Either way, it’s a great compliment to the student study bedroom… for when you are not studying, of course.
3: Laptop: MacBook Air
If you have money to spend, then the MacBook Air (11″ or 13″) is without doubt the ideal student netbook. Slightly larger than a conventional netbook, it runs Mac OS X Lion — the most advanced Mac operating system to date, and will last for hours on battery. The thinnest netbook on the market, it is incredibly light — beyond belief, in fact — and will be the envy of others around your college kid.

In terms of specs, it’s incredibly fast with a dual-core Intel i5 processor, has 4GB RAM by standard, 128GB/256GB solid state drive, Thunderbolt technology, and an LED backlit keyboard so you can even work in the dark. It’s a fantastic machine, but at its price — it’s definitely an investment rather than a disposable piece of tech to last the year!
4: Desk organisation: CableDrop
With the tech in this deck alone, the wires will be pouring out of your college kids’ ears. From televisions to games consoles, PCs and portable tech, there has to be a better way of dealing with all those cables.

My personal favourite comes in form of the CableDrop — adhesive backed cable tidies which keep cables in line, and where they should be. You may need more than one pack, however, as they will be used up very quickly. Available in a number of different colours, you may wish to buy them once you’ve moved into your dorm so you can match the colour with your desk.

Check out the rest of the stuff from BlueLounge too — some of their products are so simple, but will amaze you.
5: Games console: Xbox 360/PlayStation 3
Games consoles are tricky ones. Get the right one, and you can be making friends within minutes. Get the wrong one, and you could be the social outcast because you cannot connect to the same network as your new dorm friends.

While the two contending (and by far the best) games consoles are the Xbox 360 Elite and the PlayStation 3, it’s best to wait until you get there. Sure, you could always buy the one you think is best, but it’s one of those cautious purchases that you may regret once you realise you cannot play with anyone you know. Gaming is a social thing, especially at college. Bide your time and wait it out — but a games console is a must in student halls.
6: Headphones: Grado SR80/i
Without doubt the best headphones I have ever used. My friend Beth has a pair which her sister bought, and I tried them for a few hours on my iPod and was truly reluctant to give them back. I immediately bought a pair, and have never gone back.

Sleek and sharp, the audio quality is beyond excellent. Compatible with MP3 players with a 3.5mm connector, these headphones block out ambient noise perfectly and the bass is just to die for. Light and stylish, these headphones will end up going everywhere with you.
7: Keyboard/mouse: Microsoft Wireless Laser Desktop 6000 (V3)
Ergonomics are everything. Compatible with both Windows and Mac, this keyboard and mouse combination is ergonomically perfect and fits your writing style with precision. Incredibly comfortable to use, it also boasts a range of function keys to control your media and browsing habits.

For the price, you will not find a better keyboard and mouse combination. The keys are soft to press and gentle on the joints in your fingers — making typing out those long essays or lecture notes easier on the hands. The mouse is accurate to the pixel, making graphic design ideal for this set.
8: Camera: Canon Rebel XS
An entry level DSLR, this is the ideal complement to the creative student-to-be. It looks like a professional’s camera, without any of the added bluster of difficulty to use. Compact and light in weight, it’s easy to grip and extremely easy to use.

Shooting at 3 frames a second, you can make near-video like streams of photographs to capture the very essence of the moment. The LCD screen is sharp and bright, and really visualises photographs well, displaying full colour content to ensure you get the best view of your snaps possible.
9: Printer: Canon Pixma MG6120
For the cost, this is one of the cheapest printers for colour. An ideal inkjet printer for the new student, it prints colour images well but black text really prints out as “true black” — and none of this vague, grey-ish contrasts that so many printers provide. Though it doesn’t print out in photographic quality, it has an excellent balance of features for the cost.

It also offers Wi-Fi capabilities, allowing you to print from anywhere potentially, provided you have a WEP-encrypted network. It’s small and compact — so it’s ideal for the student dorm which offers often little space to manoeuvre..
10: Phone: iPhone 3GS
A controversial one, for sure. I put the 3GS over the iPhone 4 for one simple reason: though it is older, and lacks a high-resolution retina display — and doesn’t have video calling or a 5-megapixel camera, it’s cheaper on contract. Plus, it feels more like a phone than the iPhone 4 does. Smooth around the edges, it is far easier to hold and feels more natural in the hand.

It will also be compatible with iOS 5, which will be around in Autumn 2011, which will include iCloud functionality and a whole wealth of new features.
