Monitor your lung health by an app!


For patients with conditions like asthma, chronic bronchitis, or cystic fibrosis doctors sound out their pipes using a spirometer, a device that measures volumes of air breathed in and out. The exhaled volume indicates if the patient’s air passages are clogged and leading to difficulty breathing.

 

The Spirosmart app estimates the volume of air exhaled by the sound waves recorded as you breathe out.

SpiroCall, as the team is calling the setup, involves dialing a number and leaving a long breath of air as a voice message on a server. In very early tests, the team found that phone lines preserved enough audio quality for the recorded exhalation to be used as a spirometric substitute. This indicates that any phone, even basic cellphones that are common in developing countries, could be used to remotely measure lung health or detect signs of lung disease.

Better, brighter LEDs- inspired by fireflies.


By mimicking the jagged structure of a lightning bug’s “lantern” in a layer on top of existing LEDs, the amount of light from the semiconductor device can be increased up to 55 percent.

Buggy...!

 

Much of the light produced by LEDs gets reflected back into the device due to large differences between how light travels through the LED materials compared to air. This reduces “drastically the efficiency of LEDs,”

Here is the interesting part, similarly jagged material that they added to a standard gallium-nitride LED increased the amount of light that shone from the device by up to 55 percent!

An electronic flowerpot monitors your gardening!


For some, this may seem like a superfluous product since many varieties of houseplants don’t require an excessive amount of care. But for those with a history of killing their flowery friends, or those whose travel schedules don’t permit regular watering, Click & Grow could be a helpful solution.

Each flower-pot is wired with sensors, a processor and software that checks on the plant and provides it with fertilizer and water as needed. Each pot uses a combination of hydroponics and aeroponics, and still requires an occasional refilling of the water reservoir, about once a month.

A light on the flowerpot illuminates when the reservoir requires refilling, and the pot uses a pump to nourish the roots over time. While the pot takes care of water and fertilization, it’s up to the owner to find suitable lighting. The company recommends indirect sunlight.

The future of tumor detection?!


This is the technology in which we inject minute amounts of different cancer drugs into a tumor while it is still in the body. Once the tumor is removed, doctors can examine it to see which drugs killed its cancerous cells. The new device uses several needles to inject small quantities of drugs into a tumor through the skin into a living tumor with the needles thread narrow columns of drug through the tumor  once the tumor is removed, it is sliced into thin sections which can be stained for markers of drug activity.

technology lets researchers test live tumors to see whether a small injection of a particular cancer drug (green) will work. The red marks show tumor cells succumbing to a drug. The drug is working in the top image, but not in the bottom one.

The researchers are working on a handheld disposable version of the device and recently launched a clinical study of the technology.

A microalgae lamp that absorbs CO2!


Wow! So the future is safe? But here is the bad news that it ‘may’ encourage deforestation! these microalgae-powered lamps, invented by French biochemist Pierre Calleja, could absorb a ton of carbon from the air every year. That’s as much as 150 to 200 trees.

Magic finger-The next sixth sense?


The Magic Finger turns any surface into a touch interface. Magic Finger is a research project from Autodesk research in collaboration with theUniversity of Toronto and University of Alberta.

By combining a camera that detects surfaces with one that perceives motion, Canadian university researchers and Autodesk have made a sensor that reads finger gestures based on which part of your body you swipe. The first camera can detect pre-programmed materials like clothing, which would allow finger movements made across your pants or shirt to activate commands that call specific people or compose an email, for instance.

After taking a look at this video, you will really understand why I compared it with sixthsense. It’s truly awesome!

Power generation by urine?!


This eco-friendly energy source cranks out six hours of electricity for every liter of human bodily fluid by separating the excretion’s hydrogen with an electrolytic cell.

Though it looks promising, it  will need more than its limited safety measures before you’re able to pick one up at your local hardware store. However, if this can help us save a few bucks on our energy bill! 😛

Teleportation now possible?!


Physicists have teleported quantum information from one ensemble of atoms to another 150 metres away, a demonstration that paves the way towards quantum routers and a quantum Internet. One of the enabling technologies behind a quantum internet will be quantum routers capable of transmitting quantum information from one location to another without destroying it.

That’s no easy task. Quantum bits or qubits are famously fragile—a single measurement destroys them. So it’s not all obvious how macroscopic objects such as routers in a fibre optics network can handle qubits without demolishing them.

It relies on the strange phenomenon of entanglement in which two quantum objects share the same existence. That link ensures that no matter how far apart they are, a measurement on one particle instantly influences the other.It is this ‘influence’ that allows physicists to transmit quantum information from one point in space to another without it passing through the space in between.

There are many videos available online on youtube. This is one which I liked the most.
