Underwater Turbines

There is no more damn need for dams when it comes to harnessing water for hydroelectricity. A company has created and tested underwater turbines that have little effect on the environment. VOA News has an excellent article on why dams are problematic and why these new underwater turbines are a far better way to produce hydroelectricity.

“Taylor says one of the advantages is that it doesn’t damage marine life. “There is lots of room to swim around, they can go through, not a problem. It would be like us walking through a revolving door.””

Anti-Uranium Bacteria

Nuclear power inherently wants to kill us with its radiation, well now we can use the power of nature to fight the evils of harnessing radioactive power! Researchers have found a bacteria that eats away at uranium, which means that places like old uranium mines and weapons enrichment facilities will have less long-term damage on the environment.

“”Toxic uranium is often found in groundwater at places where uranium was either mined or enriched to make weapons,” said Craig Criddle, a professor of civil and environmental engineering at Stanford. “This uranium-contaminated water can migrate into surface waters, where it becomes a threat to organisms and water supplies. Excavation of contaminated soil or pumping and treating the water are prohibitively expensive and lead to additional disposal issues. An alternative is to stimulate naturally occurring subsurface microorganisms that can convert the dissolved uranium into a solid form that is not susceptible to transport by water.”

The ethanol stimulated growth of subterranean microbial populations that converted the uranium into an immobile form. After treatment, high levels of uranium remained on the soil, but the groundwater contained almost no uranium. Analysis of the soil-bound uranium confirmed that it was largely converted into the immobile form.”

Now, if we can only convince people to stop using nukes.

Arab League to Improve Science Literacy

SciDevNet has an article on how ALECSO will go about increasing science literacy. The strategy will encompass television shows, websites, and outreach to schools – and all to ensure people get a better understanding of science.

“The Arab League Educational, Cultural and Scientific Organization (ALECSO) has approved its first strategy for promoting science literacy as a tool for development in the 22 Arab states.

The strategy, which took four years to prepare, was approved during the annual meeting of ALECSO’s executive council, which took place in Tunis, Tunisia on 6 – 10 May.”

Caffeine Helps Infants Inhale

It seems that caffeine is proven to harm something, then another study proclaims that caffeine is actually good. Well chalk another mark for caffeine the good: caffeine helps babies breath.

“Caffeine therapy helps protect the lungs of premature infants from damage.

That’s an early finding from an international, multi-center trial designed to assess the safety of caffeine therapy for the treatment of apnea of prematurity.

Apnea of prematurity is very common in preterm infants, because their lungs are underdeveloped and the central nervous system, which automatically directs the body to breathe, is immature and often not functioning properly. It’s not known exactly how caffeine therapy helps these tiny babies breathe better, but its major benefits are believed to come from its stimulant effect on the respiratory system”

Mobile Phones Used to Help Poor

Farmers in Africa are using mobile phones to better their lives and business careers. The phones allow them to gain direct access to their respective markets and keep informed about global trends about their industry.

“One of Mashva’s neighbors said he had quadrupled his monthly income since using the phone, as he was now able to cut out a middle man who paid him far less than the market price for his cotton crop.

“Last year was really a disaster, I made around 800 rand ($120) a month and was having trouble feeding my family,” Jeremiah Chauke told reporters. “But last month I made around 4,000 rand — that’s a lot of bucks.”

Chauke has invested some of that extra cash into growing vegetables on a small plot of land near his house, which he also sells using his phone”
