ACUPUNCTURE MAY WORK LIKE DRUGS TO RELIEVE STRESS

By
The thought of having needles inserted into your body may sound stressful. But to those who regularly receive acupuncture treatments, it’s quite relaxing, though scientists haven’t really been sure why. Now researchers from Georgetown University have found that needles placed at just the right parts of the body interrupt the transmission of stress hormones—the most robust evidence yet to indicate that acupuncture’s positive effects go beyond just placebo.
“The benefits of acupuncture are well known by those who use it, but such proof is anecdotal. This research, the culmination of a number of studies, demonstrates how acupuncture might work in the human body to reduce stress and pain, and, potentially, depression,” said study author Ladan Eshkevari in a press release.
In the study, published recently in the journal Endocrinology, the researchers tested the effects of electroacupuncture, in which the needles carry a mild electric current, on stressed-out rats. They were targeting the stomach meridian point 36, which is located on the shin in humans, or behind the hind paw in rats. It’s considered in acupuncture to be one of the most powerful points on the body because it influences a pathway for chronic stress pathway called the hypothalamus pituitary adrenal axis.
When the researchers inserted needles at this point on rats that were stressed from cold, their stress hormone levels were much lower compared to those who did not receive the acupuncture treatment. Many drugs used to treat anxiety and depression tap into the same systems of hormones, bolstering the legitimacy of the findings.
If acupuncture works the same way in humans as it does in rats, it would be a promising alternative to medication; acupuncture may have fewer side effects and wouldn’t require so much tinkering with dosage. The researchers hope to test the mechanism in humans in future studies.

Wind Turbines

By
The Bahrain World Trade Center is the first skyscraper to have wind turbines integrated into the structure of the building.Three large wind turbines are suspended between two office towers. The towers are aerodynamically tapered to funnel wind and draw air into the turbines. This airfoil tapering allows the wind to enter the turbines at a perpendicular angle and increases air speed as much as 30 percent in each of the 95 ft wide turbine rotors. The turbines supply about 15 percent of the electricity used by the skyscraper - approximately the same amount of electricity used by 300 homes. Source: www.norwin.dk

Edible water balloons that could get rid of the need for plastic bottles

By
In case you didn’t know, bottled water is destroying the planet. We know that we need to be drinking plenty of water. It’s important. But the plastic bottles they’re sold in are terrible for the environment. One solution is using reusable bottles that you can fill from any nearby taps instead of buying a new bottle each time. Another solution is much more exciting. A group of engineers from Skipping Rocks Lab have developed a wonderful thing called The Ooho!. It’s a globe filled water that you can pop in your mouth whole. The outer shell is made of algae, so it’s edible and biodegradable. Meaning there’s no need for packaging or plastic – the globes of water are self-contained and ready to consume. Exciting, right? Plus they’re wobbly and they look cool, which is always a bonus. The team have now created a crowdfunding page to make their creation available to the public, with goals of selling The Ooho! at festival and marathons within the next 12 m...
