Color, meet Wheel. I think this is the beginning of a beautiful friendship.
The most interesting (to date) application of 3D printing I have seen. (Any more miniatures of the Eiffel Tower and my head will surely explode.)
In China, world’s first successful 3D-printed shoulder and collar bone implants have been performed
In Xi’an, China, the capital of Shaanxi province, 3D-printed titanium prostheses were successfully implanted into three patients suffering from cancerous bone tumors. The procedures took place on March 27 and April 3 this year and the patients are currently in good condition and recovering with their new, 3D-printed bone replacements: a collar bone, a shoulder bone, and the right ilium of the pelvis.
One of the three patients, a 20-year-old woman, was diagnosed a year ago with Ewing’s sarcoma in her right collar bone. Ewing’s sarcoma is a type of small, round, blue-celled tumor. The second patient also suffered from this disease in her right scapula or shoulder bone.
And the third patient was diagnosed with cancer in the right ilium of the pelvis. These patients all had malignant tumors which could be life threatening if not removed. Eventually, the hospital decided that operations were needed to remove the tumors and replace the affected bones. This is where 3D printing technology comes in.
A clavicle or collarbone replacement is a difficult procedure because of the complexity of the bone. With 3D-printing technology, it was possible to avoid some complications involved in the traditional procedure.
Computer imaging was used to design a collarbone in the exact size and shape of the patient’s original bone. The 3D bone design was printed using laser sintering technology which fused titanium powder into the exact shape of the bone. This process produces a strong, customized titanium implant which ensures the implant fits well in the patient’s body. Infections and loosening and can be prevented in this way and lead to better health and functionality for the patient.
tDCS validation makes me now reconsider all those folks with tin-foil hats…
In the last couple years, tDCS has been all over the news. Researchers claim that juicing the brain with just 2 milliamps (think 9-volt battery) can help with everything from learning languages, to quitting smoking, to overcoming depression.

Throughout human history, plotting populations by age group has yielded a pyramid. Across societies, the young (the base) exceeded the old (the tip).
But in recent decades, these pyramids have been morphing into rectangles and other previously unseen shapes. Just look at how the age breakdown of the U.S. population is expected to change between 1950 and 2060, in the GIF below. As early as 2030, the percentage of Americans 65 and older could surpass the percentage that is younger than 15."This is uncharted water," according to Paul Taylor, who researches demographic and generational changes at the Pew Research Center.

You can’t argue with these numbers! (via Why You Are Wrong)
Wonderful. I just wish I had the presence of mind and quickness to pull some of these out for use in my everyday life. …Of course, I’d probably be severely scarred by now.
Digging behind the headlines about factory robots and self-driving cars, wearable computers and digitized medicine, Carr explores the hidden costs of allowing software to take charge of our jobs and our lives. Drawing on history and philosophy, poetry and science, he makes a compelling case that the dominant Silicon Valley ethic is sapping our skills and narrowing our horizons.
A disturbing trend in the water sector is accelerating worldwide. The new “water barons” — the Wall Street banks and elitist multibillionaires — are buying up water all over the world at unprecedented pace.(via The New “Water Barons”: Wall Street Mega-Banks are Buying up the World’s Water | RiseEarth)
Familiar mega-banks and investing powerhouses such as Goldman Sachs, JP Morgan Chase, Citigroup, UBS, Deutsche Bank, Credit Suisse, Macquarie Bank, Barclays Bank, the Blackstone Group, Allianz, and HSBC Bank, among others, are consolidating their control over water. Wealthy tycoons such as T. Boone Pickens, former President George H.W. Bush and his family, Hong Kong’s Li Ka-shing, Philippines’ Manuel V. Pangilinan and other Filipino billionaires, and others are also buying thousands of acres of land with aquifers, lakes, water rights, water utilities, and shares in water engineering and technology companies all over the world.
The second disturbing trend is that while the new water barons are buying up water all over the world, governments are moving fast to limit citizens’ ability to become water self-sufficient (as evidenced by the well-publicized Gary Harrington’s case in Oregon, in which the state criminalized the collection of rainwater in three ponds located on his private land, by convicting him on nine counts and sentencing him for 30 days in jail).
Could New Wireless Power Transfer Unleash Electric Medicine?
Stanford University engineers say they have figured out a way to wirelessly send electric power deeper into the body than ever before.
Inventor and electrical engineering assistant professor Ada Poon created a near-field power transmitter like those used to recharge wireless toothbrushes in their cradle. The difference is that hers uses tissue between the transmitter and medical device implanted in the body to amplify the electromagnetic waves. Her team then created an electrode and receiver unit about the size of a grain of rice that can be placed wherever electrical stimulation is required.
