Scientists from the University of California have developed a small smartphone add-on for monitoring air pollution. The system uses an app called CitiSense to collect data from the sensors and allows a picture of air quality to be built. This can then be viewed not just by those with the sensors, but by other users as well. Asthmatics, for example, can figure out if they should avoid a certain area that day. It also allows scientists to monitor pollution in greater detail. In San Diego, where the first trials were carried out, there are only 10 traditional stations monitoring pollution. Researchers say that if only 100 of the area’s 3.1 million residents used the device, there would be a wealth of data that is otherwise impossible to gather.
A portable microscope that can image a single virus has been created by scientists at UCLA. It fits on the back of a smartphone and is designed to be used in places that traditional lab equipment isn’t available. One possible use is for measuring viral loads in patient samples so that doctors in remote areas can monitor the effectiveness of treatments.A slightly less powerful microscopic imaging device has been developed by engineers from Berkely. As well as potential field research applications, they believe that the devices can be good for the wider community and with that in mind gave a bunch to schoolchildren. The kids took images of items from their everyday environment and made annotations straight onto the smartphone. The people behind the device hope it could become a valuable part of the science classroom.
Today’s smartphones contain a device known as a MEMS accelerometer. It’s what figures out which way is up and flips the screen around accordingly. Seismologists from Italy’s National Institute of Geophysics and Volcanology have used the MEMS chip from an iPhone 4 and 5 to measure earthquake-scale forces. The idea is that turning smartphones into a network of seismometers will allow emergency response teams to quickly pinpoint an earthquake’s epicenter and get resources to the right places more quickly. Previous work has shown that the accelerometers can tell the difference between earthquake vibrations and everyday movements such as running.Other scientists hope to use the technology to create an early warning network. Collecting data from a large number of phones would allow scientists to predict where an earthquake is going to strike next and send a warning to anyone that has the app installed. Earthquake early warning systems have been shown to save lives, so utilizing smartphones is a cheap way of introducing the technology to areas without the need for new hardware.Via 24/7 Bebenta Sa'yo
Memorizing phone numbers
It was a hassle remembering numbers. Now we simply add them to our contacts list. That usually works well unless our device is lost, stolen, or damaged. No one can be expected to remember all their contact numbers. What we can do is memorize 5 of our most important contact numbers. This should include a mixture of family, friends and business. If you’re really ambitious you can memorize 5 contacts for each category.
Map reading skills
The convenience and effectiveness of GPS guidance systems and digital maps generated by search engines is undeniable. They’ve definitely made our lives easier. What we don’t get from using these devices and applications are the increased ability to understand spatial orientation, representative symbolism, and navigation. To renew or acquire those skills, try using physical maps to plan your next trek. Whether it’s a long or short trip, take time to stop and safely chart your progress. After a few excursions, you’ll be pleasantly surprised with how efficient a tactile map can be.
Even amateur photography required a rudimentary learning curve about lighting, depth, and composition. This was true for analog and digital photography. Most smart phone camera’s automatically make these adjustments. We no longer have to learn the art of photography. On most devices, this is easily rectified by turning off the automatic settings. Experiment with manually setting the scene modes, lighting, and zoom. You just may learn that you’re a “true Photog.”Via 24/7 Bebenta Sa'yo
Let’s face it, the ten TV channels that your college supplies is just not enough. This is where the Roku 3 comes in. Perfect for the dorms, the media device can stream all kinds of services including both Pandora and Netflix.

Solar Gear Solar Backpack
There’s no point running around campus looking for an open outlet. The Solar Gear Solar Backpack let’s the sun do all the work for you. With multiple ports, you can lounge on the green all day as the pack’s solar panels delivers power to batteries and more.
USB Roll Up Drum Kit
Dorm rooms are too small for a pair of symbols, never mind a whole drum kit. This is why a USB roll up drum kit is a lot easier to handle. Play drums directly through your computer speakers, create all types of sounds and enhance your skills before joining that new college band.
iPhone Pocket Projector
Crowding around a 13 inch dorm television is not ideal for a group of friends. Instead, turn the whole wall into a TV with the iPhone pocket projector. Play videos, look at images and stream videos from different apps.
