Airsonett, a Swedish medical tech company, is attempting make life easier for those people. It has created a device called the Protexo, which it claims should be of great assistance to night-time asthma sufferers.Read More

Banana peels can be used to purify water

The skin of a banana has been used to great comic effects in numerous slapstick routines for many years. It's also good for the skin and is a traditional cure for warts. You can polish shoes and silver with it. You can make wine with it and it's even been known to find itself being dried, wrapped in paper and smoked. Now, research published in the journal of the American Chemical Society claims that mashed up peel can remove heavy metals from river water.Read More

Carbon cloth found to be highly effective at removing pollutants

Researchers have discovered that activated carbon cloth is very effective at filtering harmful compounds out of air and liquids. The material was first developed in the 1980s, to protect British soldiers from chemical attacks. It is still in use today, in chemical, biological and radiological warfare suits for the military. This recent study, however, indicates that it could have a number of other uses.Read More

Electrified nano filter could mean cheap drinking water

Yi Cui, an Assistant Professor of Material Science and Engineering at Stanford University, has invented quite the water filter. It’s inexpensive, is very resistant to clogging, and uses much less electricity than systems that require the water to be pumped through them. It also kills bacteria, as opposed to just trapping them, which is all that many existing systems do. Read More

Stellenbosch University's Hope Project patents 'tea bag' water filter

Stellenbosch University's Hope Project has produced a disposable water filter shaped like a tea bag. When placed in the neck of a water bottle, the bag removes all harmful chemicals and microbes. Each bag cleans one liter (1.06 quarts) of water, so a lot will be needed to make any significant impact on water-related health issues globally. However, when compared to competition such as the LifeStraw or LifeSaver, it would seem to be a cost effective solution. The product is currently being tested by the South Africa Bureau of Standards.Read More

The Emergency Bra that doubles as a facemask

Sexy red lingerie and heavy breathing have traditionally gone hand in hand. But a bra from inventor, Dr. Elena Bodnar, is designed to let people breathe easier. Her Emergency Bra is a protective device that transforms from a bra into two respiratory pace masks to filter out harmful airborne particles, such as those released by fire, explosion, terrorist, radiological, biological attack, and natural disasters.

New high-speed, low-cost water purifying nanofilter developed

As their name suggests, most existing water purifying filters clean the water by physically trapping or filtering out bacteria. Stanford researchers have now developed a new kind of water purifying filter that isn’t really a filter at all. Instead of trapping bacteria, the new filter actually lets them pass right through. But, by the time they emerge from the filter they have been killed by an electrical field running through it. Not only is the new filter more than 80,000 times faster than existing filters, it is also low-cost, has no moving parts and uses very little power, which should make it particularly attractive for use in the developing world where it is needed most.Read More

“Devuvuzelator” filters vuvuzela from World Cup coverage

Riddle me this. What sounds like an elephant when all alone, but sounds like a swarm of bees when numbers grow? The answer, as any World Cup aficionado will tell you, is the vuvuzela. A meter long plastic horn that has become synonymous with the 2011 World Cup in South Africa and has had many fans reaching for the mute button on their TV remote controls. The BBC has received so many complaints it is looking at ways to minimize the noise of the so-called instrument. Now researchers at the Centre for Digital Music (C4DM) at Queen Mary, University of London have come up with a "devuvuzelator" that filters out the droning sounds of vuvuzela for anyone watching the World Cup on a computer.Read More
