back into the Dark Ages

Published on Dec 16, 2015
“It could plunge medicine back into the Dark Ages.” Overuse of antibiotics on Chinese pig farms has led to a strain of bacteria becoming resistant to the last effective antibiotic we had. And it’s spreading. Could this be the start to the post-antibiotic era? Find out more on this episode of China Uncensored.

What Makes Us Happy?

Is there a formula—some mix of love, work, and psychological adaptation—for a good life? For 72 years, researchers at Harvard have been examining this question, following 268 men who entered college in the late 1930s through war, career, marriage and divorce, parenthood and grandparenthood, and old age. Here, for the first time, a journalist gains access to the archive of one of the most comprehensive longitudinal studies in history. Its contents, as much literature as science, offer profound insight into the human condition—and into the brilliant, complex mind of the study’s longtime director, George Vaillant.

Breathing Exercises

Once you develop this breathing technique by practicing it every day, twice a day, it will be a very useful tool that you will always have with you. Use it whenever anything upsetting happens – before you react. Use it whenever you are aware of internal tension. Use it to help you fall asleep. Use it to deal with food cravings. Great for mild to moderate anxiety, this exercise cannot be recommended too highly. Everyone can benefit from it. Learn more about Breathing Exercises.

Toby Hemenway shares his perspective on native plants. He is a powerful advocate of native plants. And, at the same time, is concerned that the passions of some other native plant advocates might lead down a path that is not as good for native plants. Specifically, the planting of exclusively native plants vs. planting of an edible garden.

Toby also explores the idea of “native to when?” with a focus on douglas fir trees.

Gravity-Driven Membrane (GDM) technology

Inadequate access to microbiologically safe drinking water continuously threatens the health and well-being of more than a billion people, primarily in developing countries. In many areas worldwide the central water infrastructure is not available at all, or not reliable, leading to unsafe water at the tap. In such cases, decentralized water treatment can be used.

Ultrafiltration is an effective technology to treat water and in principle can be applied on a decentralized scale. Most ultrafiltration membranes have pores which are smaller than the size of bacteria and viruses. Thus, water filtered through these membranes is microbiologically safe.

During dead-end ultrafiltrtion all macro- and microorganisms, particles and colloids accumulate on the membrne surface and a fouling layer is formed. Backflushing or chemical cleaning are usually used during conventional ultrafiltration to remove fouling layer. This prevents the membrane from clogging, which is expected to occur during filtration on a long term. However, backflushing or cleaning results in complex and maintenance-intensive systems, which are difficult to operate on a long term in developing countries.
