Imaging Technique Unlocks the Secrets of 17th Century Artists
By John Toon – The secrets of 17th century artists can now be revealed, thanks to 21st century signal processing. Using modern high-speed scanners and the advanced signal processing techniques, researchers at the Georgia Institute of Technology are peering through layers of pigment to see how painters prepared their canvasses, applied undercoats, and built up layer upon layer of paint to produce their masterpieces.
The images they produce using the terahertz scanners and the processing technique – which was mainly developed for petroleum exploration – provide an unprecedented look at how artists did their work three centuries ago. The level of detail produced by this terahertz reflectometry technique could help art conservators spot previous restorations of paintings, highlight potential damage – and assist in authenticating the old works.
Beyond old art, the nondestructive technique also has potential applications for detecting skin cancer, ensuring proper adhesion of turbine blade coatings and measuring the thickness of automotive paints.
Without the signal processing, researchers might only be able to identify layers 100 to 150 microns thick. But using the advanced processing, they can distinguish layers just 20 microns thick. Paintings done before the 18th century have been challenging to study because their paint layers tend to be thin, Citrin said. Individual pigments cannot be resolved by the technique, though the researchers hope to be able to obtain that information in the future. more>

Matrix Reimagined: Brand New GE Startup Is Developing Novel Ways To Draw Blood
Ny Tomas Kellner – Drawbridge, a new business founded by GE Ventures, is building an easy-to-use blood collection device that could be used anywhere — at a clinic in San Francisco, in a remote village in Borneo or potentially even at home. Users will be able to apply the device to the upper arm and activate it. It will then store and stabilize the sample in a special cartridge.
Drawbridge, a new business founded by GE Ventures, is building an easy-to-use blood collection device that could be used anywhere — at a clinic in San Francisco, in a remote village in Borneo or potentially even at home. Users will be able to apply the device to the upper arm and activate it. It will then store and stabilize the sample in a special cartridge.
The playing field is huge. The global blood collection market stands at $7 billion, and health professionals in the U.S. alone draw more than 1 billion blood samples every year. Handling blood is also an important factor in treating patients — blood test results reportedly influence 70 percent of clinical decisions.
The blood stabilization technology inside the device, a high-tech paper-like material known as “the matrix,” was originally developed by scientists at GE Global Research, leveraging knowledge and expertise from the GE Healthcare team.
The collection device will draw a small amount of blood and channel it onto the matrix, which stores the sample for later extraction and testing. The matrix also stabilizes the collected blood sample and eliminates the need to refrigerate it, which will simplify transporting it to the lab.
When GE Ventures learned about the technology, Stack and her colleagues thought they could build a business around it, as they did with other companies they’ve launched. more>
Love At First Touch: Brazilian Doctor Uses 3D Printing To Help Blind Parents Feel Baby’s Ultrasound
By Erica Firmo – When Ana Paula Silveira got pregnant, she and her husband, Alvaro Zermiani, dreamed about seeing the face of their child during her first ultrasound exam. But weeks later, they got to feel it instead.
Both Ana Paula and Alvaro, who live in São Paulo, Brazil, are legally blind. Their son, Davi Lucas, was strong and healthy, but there was no way their eyes could see the first grainy glimpses of their baby on the ultrasound monitor.
They decided to take a different path. The couple made a trip to the office of Dr. Heron Werner, a gynecologist and obstetrician working at the DASA clinic in Rio de Janeiro. He agreed to follow Ana Paula through her pregnancy.
Dr. Werner uses a 3D printer to make lifelike models from images obtained by a GE ultrasound machine. “From the moment we got to the high-quality ultrasound exam, through the possibility of 3D printing it, I realized that it could also serve to enhance the prenatal experience of visually impaired pregnant women,” Dr. Werner says. more>
Daydreaming is Good. It Means You’re Smart
By Jason Maderer – A new study from the Georgia Institute of Technology suggests that daydreaming during meetings isn’t necessarily a bad thing. It might be a sign that you’re really smart and creative.
“People with efficient brains may have too much brain capacity to stop their minds from wandering,” said Eric Schumacher, the Georgia Tech associate psychology professor who co-authored the study.
Schumacher says higher efficiency means more capacity to think, and the brain may mind wander when performing easy tasks.
How can you tell if your brain is efficient? One clue is that you can zone in and out of conversations or tasks when appropriate, then naturally tune back in without missing important points or steps.
“Our findings remind me of the absent-minded professor — someone who’s brilliant, but off in his or her own world, sometimes oblivious to their own surroundings,” said Schumacher. “Or school children who are too intellectually advanced for their classes. While it may take five minutes for their friends to learn something new, they figure it out in a minute, then check out and start daydreaming.” more>

By Robert Schlesinger – What’s going on? If everyone agrees on these successful programs, why are they stuck in legislative purgatory?
The proximate cause is that the Republican majority got too distracted with its endless, fruitless attempts to roll back the Affordable Care Act. That consumed their attention through the year and very specifically in the crunch time during which the final deals should have been cut on basically noncontroversial legislation like renewing funding for CHIP and community health centers. But that went by the boards when the GOP dropped everything to push the late, unlamented, half-baked Graham-Cassidy bill.
Uncertainty abounds. And again, we’re talking about noncontroversial stuff here, which speaks to a larger problem with the political system. The failure of this Congress to understand “the need to act responsibly, to reauthorize needed programs without catastrophic disruption … is simply striking,” says the American Enterprise Institute’s Norm Ornstein, who has written extensively on GOP dysfunction (most recently “One Nation After Trump,” with Thomas Mann and E.J. Dionne). more> https://goo.gl/1xQG84

By Amy Kover – Standing on a 10-foot-wide platform 365 feet above the rolling green hills of Tumbler Ridge, British Columbia, Kristen Hough looks tiny. The winds at this height are strong enough to spin a 500,000-pound wind turbine at 14 revolutions per minute. One strong gust could push a person over.
But Hough, 28, also looks unafraid. A wind technician, Hough is part of a team that is responsible for the electrical and mechanical upkeep of 61 turbines here that can produce 185 megawatts of energy — enough to power an entire city. She makes the climb to the top of a wind turbine at least once a day. At that height, Hough is in her element. “Even climbing the turbines [the first few times], it was so exciting that I knew it was what I was supposed to do,” she says.
Hough’s shift typically begins each morning at 7 a.m. when lead technician Mitch Burns assigns Hough and her five teammates to either handle routine maintenance — like tightening bolts and greasing gears — or troubleshoot problems. For instance, if the temperature in the gearbox appears a bit high, Hough needs to figure out why and fix it. Sometimes she can resolve the issue with a few taps on her laptop, but it -often requires hands-on attention instead. That’s when Hough gets out her safety gear and starts the long ascent to the top of the turbine. more> https://goo.gl/vWg2At

New Center Helps Scientists Reprogram The Immune System to Kill Cancer
By Tomas Kellner – Cell therapy is a complex process that involves more than manufacturing a pill. It requires a setup that resembles a biotech factory. “Cell therapy has the potential to cure everything from cancer to diabetes,” says Phil Vanek, general manager for cell therapy growth strategy at GE Healthcare. “But we need to make it affordable and scalable.”
Vanek’s business and others are racing to make that happen and deliver on cell therapy’s promise. He says that says that hundreds of patients have already benefited from CAR-T in clinical trials that have reported 80 percent success rates. Some 300,000 people could be receiving the treatment by 2024. A report by Roots Analysis estimates the T-cell therapy market, which includes CAR-T therapy, could read $30 billion by 2030.
Crucial to that race is a new cell therapy research and process-development facility called the Center for Advanced Therapeutic Cell Technologies (CATCT), which officially opened in Toronto on Thursday. It’s designed to help pharma companies, university researchers and technology companies like GE to scale faster. more> https://goo.gl/CRxNv4

Driving Cassini: Doctoral Student Controls Spacecraft in Mission’s Final Days
By Jason Maderer – When the Cassini spacecraft plunges into Saturn on September 15 to end a nearly two-decade mission, Georgia Tech student Michael Staab will have a front row seat. It’s almost literally the driver’s seat.
Staab is working at NASA’s Jet Propulsion Laboratory (JPL) in California while pursuing his aerospace engineering doctoral degree in the distance learning program. He’s a Cassini Spacecraft Flight Controller, which means he’s one of only three people authorized to tell the machine what to do and where to go as it orbits Saturn.
The job is almost finished. Just before 8 a.m. (Atlanta time) on Friday, Staab will hear Cassini’s signal for the final time before it dives into the planet’s atmosphere, becoming a part of Saturn.
Prior to attending Georgia Tech, I was a flight test engineering intern at NASA’s Armstrong Flight Research Center at Edwards Air Force Base in California and, later, a test requirements and analysis engineer for Boeing in St. Louis. I had a lot of control room and operations experience, which is exactly what JPL was looking for.
The duty of a flight controller at JPL is fairly straight-forward; we possess absolute command and control authority of the spacecraft when tracking it through the Deep-Space Network. more> https://goo.gl/aAU76G
