TED Talk Thursday – A new weapon in the fight against superbugs by David Brenner

According to TED.com : “Since the widespread use of antibiotics began in the 1940s, we’ve tried to develop new drugs faster than bacteria can evolve — but this strategy isn’t working. Drug-resistant bacteria known as superbugs killed nearly 700,000 people last year, and by 2050 that number could be 10 million — more than cancer kills each year. Can physics help? In a talk from the frontiers of science, radiation scientist David Brenner shares his work studying a potentially life-saving weapon: a wavelength of ultraviolet light known as far-UVC, which can kill superbugs safely, without penetrating our skin. Followed by a Q&A with TED Curator Chris Anderson.”

“David Brenner directs the Center for Radiological Research at Columbia University Medical Center in New York City and has numerous distinctions within his field such as the Oxford University Weldon Prize and the Radiation Research Society Failla Gold Medal Award. Founded by a student of Marie Curie more than a century ago, the Center for Radiological Research is committed to exploiting all forms of radiation to improve medical care.”

“As Brenner sees it, radiation is very much a two-edged sword — used in the right way it has revolutionized modern medicine, such as through CT scans and as a cure for many cancers. But radiation used in the wrong way can be harmful. To maximize the benefits of the many different types of radiation, we need to understand exactly how they affect us, from our DNA to the whole person.”

“Over the past six years, Brenner and his team have applied this idea in working towards a safe way to kill drug-resistant bacteria such as MRSA, as well as airborne microbes such as influenza and TB, using a unique type of ultra-violet light, known as far-UVC.”

“In short, it is pure physics — far-UVC light is safe for us because it cannot even penetrate through the dead-cell layer on the surface of our skin or the tear layer on the surface of our eyes. But because bacteria and viruses are physically very small, far-UVC light does have enough penetration to efficiently kill them.”

For those of you not familiar with TED Talks here is a brief summery from www.ted.com: “TED is a small nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, Design. Since then its scope has become ever broader. Along with two annual conferences — the TED Conference in Long Beach and Palm Springs each spring, and the TEDGlobal conference in Oxford UK each summer — TED includes the award-winning TEDTalks video site, the Open Translation Project and Open TV Project, the inspiring TED Fellows and TEDx programs, and the annual TED Prize”

Mandala Monday – How to paint rock mandalas #5- Rainbows by Kristin Uhrig

How to paint rock mandalas #5- Rainbows by Kristin Uhrig is the tutorial for today. You may remember a previous post featuring her tutorials at How to paint rock mandalas #4- Christmas design by Kristin Uhrig that we posted last December.

Here is what Kristin has to say about this tutorial: “In this video, I will show you where to purchase perfect rocks for painting when you don’t have access to rocky beaches or river banks. Then, I will demonstrate five different dot mandala painting patterns on stones using rainbow colors. Dotting tools are from Traveling Kindness Rocks and can be purchased online. They work great!”

Enjoy and happy painting!

Here is what Kristin says about her mandala making:

“I have been on a journey to learn a new painting technique to relieve the stress brought on through a medical crisis with my husband’s cancer. A camping trip resulted in a fine collection of smooth flat, round stones. They were the inspiration for learning to create dot mandala designs on rocks, and then late on canvas panels. I began making tutorials to share this adventure with others, so they could learn from my mistakes as well as my successes. My hopes that others will be encouraged to try something new, and creat beautiful lasting pieces of art that will bring them joy.

TED Talk Thursday – How artists can (finally) get paid in the digital age by Jack Conte

According to TED.com : “It’s been a weird 100 years for artists and creators, says musician and entrepreneur Jack Conte. The traditional ways we’ve turned art into money (like record sales) have been broken by the internet, leaving musicians, writers and artists wondering how to make a living. With Patreon, Conte has created a way for artists on the internet to get paid by their fans. Could payment platforms like this change what it means to be an artist in the digital age?”

“As a solo artist and member of folk-rock duo Pomplamoose, Jack Conte garnered millions of views for his offbeat “video songs,” including his breakout hit “Yeah Yeah Yeah” and “Pedals,” a robotic tour-de-force with a set that duplicates the cockpit of the Millennium Falcon.”

“Despite his success, Conte noted the disconnect between page views and revenue, and he realized that if you’re a widely viewed artist and you aren’t making money, “that’s not your fault — it’s technology’s fault.” His solution is Patreon: a membership platform built on recurring payments from patrons to support creatives with ongoing projects.”
