NaturalNews: There's more to H2O than meets the eye. Life-threatening amounts of heavy metals like arsenic can go undetected in drinking water, ultimately destroying the health of entire communities. The most acute exposures are witnessed in countries like India and Bangladesh, where people show signs of arsenic poisoning, or arsenicosis. Arsenic poisoning can cause painful lesions, diabetes, cancer, blood vessel diseases and gangrene, forcing some to undergo amputation or be ostracized from their village.
Technology that removes arsenic from drinking water is often donated to villages in South Asia that drink from highly contaminated tube wells. Many of these reverse osmosis systems last less than six months and, on a grand scale, do not solve the problem, as thousands still suffer.
Facebook eyes up the use of drones to deliver Internet...
Company founder Mark Zuckerberg announced Facebook’s ambitious plan to bring Internet access to the parts of the world without it through drones. Its Connectivity Lab could become a major competitor with Google’s Project Loon
Facebook is friending drones.
The social network’s founder Mark Zuckerberg revealed Thursday that the company’s ambitious plan to bring Internet access to the parts of the world without it will use drones to do. A year after announcing the Internet.org project, Zuckerberg said Facebook’s Connectivity Lab is making progress as it works to “build drones, satellites and lasers to deliver the internet to everyone.” The project will do nothing less, he said, than “beam internet to people from the sky.”
“Over the past year, our work in the Philippines and Paraguay alone has doubled the number of people using mobile data with the operators we’ve partnered with, helping 3 million new people access the internet,” Zuckerberg wrote on his Facebook page. “We’re going to continue building these partnerships, but connecting the whole world will require inventing new technology too.”
NaturalNews: Stress is such a common occurrence in our daily lives that we have come to the point where we barely question its presence. And yet, when we ignore these heightened states of pressure, our physical, mental and emotional health suffers. But it doesn't have to be this way. Taking a cue from those who are cool under fire, we can transform our daily experience into one that is productive, relaxed and actually enjoyable
One cup of joe and your brain is ready to go”? – Caffeine as memory enhancer
The first systematic study investigating the effects of caffeine on human performance – sponsored by Coca-Cola – has been published about 100 years ago. Since then, thousands of other studies have been looking at if and in which ways caffeine improves cognitive performance. This question is still debated in science, but there is general consensus that caffeine can be seen as an enhancer for specific functions like mood, attention, concentration and reaction time. These enhancement effects have been shown in studies with the general set-up that participants first took caffeine and then did a performance task. This matches our everyday representation of “wise” caffeine use: if I wanted to enhance my performance with caffeine, I’d take it immediately before the “critical situation”, for example an exam
