Mobile medicine: the tricorder emerges into reality

“Along with teleportation, speech-driven computers and hand-held wireless communicators that flip open, the medical tricorder was one of many imaginary future technologies featured in “Star Trek”. Ever since, researchers have dreamed of developing a hand-held medical scanner that can take readings from a patient and then diagnose various conditions. Now, nearly five decades after “Star Trek” made its debut in 1966, the dream is finally edging closer to reality.”
“…[AliveCor] has developed an iPhone case with two electrodes that can perform an electrocardiogram (ECG). Dr Topol recently used a prototype to assess a fellow passenger on an aircraft who was suffering from chest pain. He concluded the passenger was having a heart attack, and the plane was diverted. Other firms are also developing medical add-ons for smartphones. MobiSante, based in Redmond, Washington, has devised a smartphone-based ultrasound system that was grantedFDA clearance in early 2011. A hand-held ultrasonic probe plugs into a smartphone, which generates and displays an image. It costs $7,500, a fraction of the price of a conventional ultrasound.

Internet emits 830 million tonnes of carbon dioxide

Internet and other components of information communication and technology (ICT) industry annually produces more than 830 million tonnes of carbon dioxide (CO2), the main greenhouse gas, and is expected to double by 2020, a new study has found.  Researchers from the Centre for Energy-Efficient Telecommunications (CEET) and Bell Labs explain that the information communications and technology (ICT) industry, which delivers Internet, video, voice and other cloud services, produces about 2 per cent of globalCO2 emissions -- the same proportion as the aviation industry produces.  In the report published in journal Environmental Science & Technology, researchers said their projections suggest that ICT sector's share in greenhouse gas emission is expected to double by 2020.  They have also found new models of emissions and energy consumption that could help reduce their carbon footprint.  The study said that controlling ...

Bruisable gadgets heal themselves in the sun

Image
GADGETS of the future could bruise when dropped or scratched to highlight damaged areas. Don’t worry though, as a few minutes in the sun will be enough to fade the bruise and repair the damage. Marek Urban and colleagues at the University of Southern Mississippi in Hattiesburg were inspired to create their self-healing plastic by signs of healing in nature such as newly formed tree bark.  Earlier self-healing materialsMovie Camera do not change colour and require focused laser light for repairs. This new material turns red when damaged and repairs itself when exposed to visible light or changes in temperature or pH. It can also fix itself multiple times, unlike previous materials.  Like all plastics the new material contains long chains of polymers, except that the chains are linked by small molecular bridges that break and change the plastic’s shape when it is scratched. This shape-change produces the bruise, which disappears when energy from the light enables the b...

How To Bypass The Lockcode Screen On IOS 6.1 And Use Anyone’s IPhone

Image
Apple has had a few problems with its latest iPhone and  iPad software update . Released just last month, iOS 6.1 was meant to be a relatively significant update bringing enhanced Siri capabilities, LTE support to more countries, and more iTunes Match features. But it seems as if the update is doing more harm than good. The Verge reports that a new bug, "lets anyone bypass your iPhone password lock and access your  phone app , view or modify contacts, check your  voicemail, and look through your photos (by attempting to add a photo to a contact)." The instructions are pretty simple. First you have to pretend to turn the phone off, then make an aborted  emergency call , then a quick bit of off button and cancel pressing. That boots you into the full  phone app  where you can pretty much call or  message  anyone you like, or edit phone contacts. Besides allowing anyone access to your phone, Apple's latest software update also drains your batte...
