Lifestraw a Life Saver

he looks highGlobally, about 6,000 people a day die from water-borne disease. These are preventable deaths but, in many places it is too expensive to provide clean water for everyone and as a result people contract water-borne diseases. A fancy new drinking straw can stop 99.99% of parasites and bacteria from drinking water.

It’s called the Lifestraw and is currently being tested in the field. It is not as small as your average straw, but it’s small enough to wear around your neck. The manufacturing costs are low too – only $3 per unit. 70,000 units were handed out to earthquake victims in Kashmir last year. More testing is needed, but this is off to a very promising start!

Thanks, Kathryn!

Gas: A Real Knockout

Some researchers have found that stinky sewer gas can really knock you out. They found that they could put mice into a state of near suspended-animation by exposing them to the smell.

“Hydrogen sulphide, a toxic gas that smells of rotten eggs, occurs naturally in swamps, springs and volcanoes.

But in mice, it was found to slow down heart rate and breathing and decrease body temperature, while keeping a normal blood pressure.”

Put Your Leftovers in Your Car

wow!It seems like that neat engine, which is powered by trash, in that car from Back to the Future is almost real! Researchers at UC Davis have found a way to turn leftovers from meals into biogas that can be used to generate electricity or make fuel. That in itself is not revolutionary, what is though, is that they found an effective (cheap) way to do this on a large scale.

The machine will use leftovers from restaurants to make energy, thus making it also a waster-diversion program to boot.

“The Biogas Energy Project is the first large-scale demonstration in the United States of a new technology developed in the past eight years by Ruihong Zhang, a UC Davis professor of biological and agricultural engineering. The technology, called an “anaerobic phased solids digester,” has been licensed from the university and adapted for commercial use by Onsite Power Systems Inc.”

Researches Battle Tropical Diseases

A group of scientists have agreed to work together to fight tropical disease by making drugs that the larger pharmaceuticals aren’t researching. The researchers met in Nairobi to solidify their relationship to improve health in Africa.

“By working together in regional, needs-driven research platforms we are not only on the way to addressing the lack of capacity but also helping in the trials for new drugs,” said Davy Koech, director of the Kenya Medical Research Institute.”

Study At Yale – For Free!

Studying at Yale is beyond the means of most, with high admissions standards and a hefty price tag of about $46 000 a year for tuition and board.  Now, thanks to a new initiative to make the Ivy League school more accessible and a $755 000 grant, courses will be available for free on the internet.

This facility is already offered by other institutions including the likes of MIT and Princeton, Yale will be the first to offer videos to accompany course notes and transcripts of lectures. The initiative will include 7 first year courses.

The courses will not be counted as credits towards a Yale University Degree, nor will they substitute normal lectures.
