[MONTEVIDEO] Banana peels can be used to purify drinking water contaminated with toxic heavy metals such as copper and lead, according to a study.

Researchers from the Bioscience Institute at Botucatu, Brazil, said that the skins can outperform even conventional purifiers such as aluminium oxide, cellulose and silica. These have potentially toxic side effects and are expensive.

The team’s method follows previous work that showed that plant parts, such as apple and sugar cane wastes, coconut fibres and peanut shells, can remove toxins from water.

PTV has decided to reproduce this article featured in the Huffington Post as it fits into the PTV belief system:-

When there are natural or manmade disasters — even if they are half a world away — most of us are glued to the television or our favorite news source on the Web, checking frequently for the latest update. We can become completely obsessed with what’s happening.

This obsession is actually there for most of us all the time. That’s why news sources are as popular as they are. When the event becomes big enough, however, this obsession can become painfully obvious. It’s not that there’s anything wrong with keeping informed about current events and responding appropriately. It’s just that, at times like this, many of us have a hard time disconnecting from what is unfolding.

Cole Rasenberger’s quest to save forests in the US South started as a school assignment to ‘be an activist’ about something important to him.

He started by targeting McDonalds directly. With the help of 25 friends, and his elementary school administration, he got every student in his school to sign postcards to McDonalds. In all, Cole sent 2,250 postcards to McDonalds.

Five nations in Africa have come together to create the world’s largest conservation area for wildlife.

Elephants have no respect for lines on a map, especially the artificial national boundaries established by Europeans after carving up Africa into colonial empires. But national boundaries have kept elephants and many other animals cooped up in southern Africa.

Thousands of gallons of free water fall on roofs, parking lots, and sidewalks every day only to flow directly down the drain. Rainwater collection systems are often bulky and (in some regions) illegal. But with the Save Water Brick, your home and other buildings could collect this precious resource automatically.

Land-scarce Singapore has its first vertical farm on a plot of land in Lim Chu Kang the size of about five football fields.

Vegetables – Chinese cabbage, nai bai and xiao bai cai – grow on 120 towers and the harvest is sol

A new study is investigating how to help deaf people who have received a cochlear implant to get more enjoyment from music.

Cochlear implants allow people with severe-to-profound hearing loss, who do not substantially benefit from conventional hearing aids, to perceive and understand speech. However, the current technology often cannot cope with the complexities of music.
