Cover the Earth

Since 1905 Sherwin-Williams has used the slogan "Cover the Earth" to promote the beauty and performance of their paints.  A French artist is now making a real attempt to cover the earth with giant paintings on the hillsides of Switzerland.

A self-taught artist, Saype got his start by creating innovative and eye-catching graffiti on the transit trains of Paris and Brussels.  He has also painted on canvas, again featuring scenes from trains.

Another innovation Saype has adopted is the use of multiple plexiglass panels to form a scene - thinking 'outside-the-canvas.'  By painting part of the scene on each panel and stacking them he makes the works more 'dynamic.'  He sometimes lights the interstices between the panels with LEDs to further enhance the underground feeling.

In 2015 Saype initiated the latest phase of his career that he calls 'Land Art.' Once he has identified a suitable site he first cuts the grass low.  He next outlines the figures on the grass. Then, using a special bio-degradable paint that he prepares himself, he uses a spray gun to fill in his picture in a gigantic paint-by-numbers type process.  He has used drones to review his progress and for photographing the works. 

About 150 gallons of paint were needed to create Saype's most recent work entitled 'A Story of the Future,' featuring a small child reading a book on a hillside in Les Rochers-de-Naye in Veytaux, Switzerland. Each petal of the flowers in the picture is about the height of a man.  The entire picture covers more than the area of a football field.

The works are ephemeral.  Soon the grass begins to grow back and the weather begins to change the picture.  Eventually the picture disappears altogether, so check them out while you can.

So the next time you see a particularly nice piece of graffiti on the metro train, rather than scorn it as defacement, consider whether it might be an early work of a budding artistic genius.  Drink in whatever creativity or innovation that you find there, and think of how you could create a gigantic impression in your work by thinking outside the canvas or outside the computer.

Check Your Bioprivilege

We’ve all heard that some people are considered to be privileged by means of their age, sex, race, economic status, or whatever.  But what about molecules?  Are there some that are more privileged than others?

Researchers at the National Science Foundation Engineering Research Center for Biorenewable Chemicals (CBiRC) at Iowa State University have coined the term ‘bioprivileged’ for molecular intermediates that are made by plants and animals that are not conveniently made by industrial processes.  These privileged molecules offer “unique properties that could lead to new products.”

The range of chemical intermediates that can be derived from petroleum has been developed for more than a century, and there are few new avenues for discovery.  However, the universe of molecules that can be obtained from living systems is much greater – there are many more different types of molecules in a typical plant than are produced in all of the chemical industry – and can “greatly expand the bioproduct horizon beyond the scope of petrochemicals.”    

Modern genetic engineering is expanding this universe and is able to selectively design plants to produce specific valuable products.  Among the targets that can be produced are the next-generation pharmaceuticals, nutraceuticals, antimicrobials, insecticides, herbicides, consumer goods, and specialty chemicals.  At CBiRC they have already made plant-derived nylon.

So, in addition to checking your privilege, check out the wonders that are happening at CBiRC or at a laboratory near you.

Fixing a Hole

'Fixing a hole where the rain gets in' was a reflection on the difficulties presented by persistent fans for the Beatles. But the hole that appears in the sun right now may present a different set of difficulties for us earthlings.

The hole in the sun is a gap in the sun’s magnetic field where charged particles are being expelled at speeds up to 500 miles per second (1.8 million miles per hour!). It’s not small like a sunspot, it’s something like 50 earths wide. The strong solar wind being ejected is producing fantastic auroras as it hits the earth’s atmosphere. These ionized particles can also influence radio transmissions, which could impact all types of communications on earth. And the solar wind has been implicated in the production of clouds, clouds that have a direct influence on earth’s weather.

The hole has been followed by a ‘prominence eruption’ in which a gas cloud loosely held by the sun’s magnetic field suddenly falls apart with much of the mass being shot out into space. If these eruptions are directed our way they can cause magnetic storms here on earth.

One such solar storm, known as the Carrington event, hit earth in 1859. In that storm a solar prominence eruption hit Earth's magnetosphere and induced perhaps the largest geomagnetic storm on record. English astronomer Richard C. Carrington observed a so-called ‘white light flare’ on the sun at the time. A similar sized solar storm occurring today would likely disrupt all sorts of electrical systems that are critical to modern civilization. In 2012 a huge solar storm occurred, but it was directed away from earth, saving us from any problems.

Last month our neighborhood star featured a rather unusual collection of three coronal holes appearing together. The coronal holes are the dark areas in the photographs – these are false color images taken in ultraviolet wavelengths that are invisible to the human eye.

There is a great deal that we do not understand about the sun, including how features like coronal holes and prominence eruptions form. What we do know is that the sun supplies the energy for life on earth, so we continue to study it.

Young Blood

Juan Ponce de Leon famously searched for the Fountain of Youth in Florida. According to recent research, perhaps he would have had more success if he had been imitating Nosferatu and consuming blood from the young.

According to experiments on mice by teams of researchers at Harvard, Stanford, UC Berkeley, UC San Francisco, and elsewhere, young blood rejuvenates tissues and organs including muscles, liver, heart, and brain, when injected into old mice.

In one study the researchers surgically connected the circulation systems of each old mouse with a young mouse, thus allowing the young blood to flow into the old mouse. Their results showed a substantial reversal of nervous system aging in the older mice. They concluded:

“Our data indicate that exposure of aged mice to young blood late in life is capable of rejuvenating synaptic plasticity and improving cognitive function.”

Results with the mice look so promising as a potential treatment for Alzheimer’s, that a biomedical startup called Alkahest has started running a small clinical trial that involves injecting human blood plasma from young people into dementia patient volunteers. Half of the recipients will receive 4 weekly injections of young blood while the other half will act as a control group and receive injections of a placebo (saline solution). They will be monitored for a year and results are expected to be available in October 2015.

In related work, researchers are trying to identify the factor(s) in young blood that are responsible for its effect on aging. A paper from Lee Rubin et al of Harvard has identified and tested a protein called growth differentiating factor 11 (GDF-11) that has shown unexpected ability to reverse the effects of aging on the brains of mice.

Another Harvard researcher, Amy Wagers, leads a team that has been utilizing GDF-11 for several years to improve muscle function in mice. In one study Wagers has found that increased GDF11 levels in aged mice improved muscle structure and function, providing increased strength and endurance.

Perhaps the next time I  babysit my grandchildren I should ask to be paid in blood.

Robots Will Rule

Robotics is a rapidly advancing field that will do more to change our lives in the next few decades than any other technology. From humble beginnings with the commercial automated vacuum, Roomba, these mechanical assistants can do everything from perform surgery to manufacture autos to conduct military operations. One cannot open a newspaper without reading about drones that deliver packages, monitor traffic, or carry out bombing missions. Drones are just one example of the possibilities with flying robots.  

In addition to the large scale applications, scientists and engineers are developing micro-robots that may help with searches of confined spaces or be implanted into one’s body to conduct medical procedures as in "Fantastic Voyage” by Isaac Asimov. Of course, like any technology, these microrobots could be turned to evil as in Michael Crichton’s posthumous novel “Prey,” where swarms of nanorobots invade and devour their prey.

Real life micro-robots are being developed by Sarah Bergbreiter at the University of Maryland. In a recent TED talk she demonstrates how she can make simple robots the size of a grain of rice walk and jump. Bergbreiter and her students are working on micro structures and systems for locomotion, sensing, actuation, power, and systems integration.

One of these micro-robots, no larger than a breath mint, and powered by light, is able to jump over 100 times its own height. Another micro-robot is able to 'run' ten times its body length per second. A human performing these feats would be jumping a building 50 stories high and running a 5 second 100-meter dash! Bergbreiter uses fabrication techniques pioneered in the electronics industry to prepare micro-actuators that propel these little guys.

It will not be long before these micro-robots leave the lab and become part of our lives.

Absence Makes the Communications Flow Better

You've heard the knock on virtual teams. "Our team will communicate better when we are all together." Obvious, right?

Not so fast. It turns out that a small team communicates best when one - and only one - member is situated at a distance. At least that's the conclusion of a paper entitled: "Subgroups, Imbalance and Isolates in Geographically Dispersed Teams," in a 2008 article in Organization Science. 

Michael Boyer O’Leary, of Boston College’s Carroll School of Management and Mark Mortensen, at MIT’s Sloan School of Management studied 62 six-member teams split between locations in the US and Canada. Configurations of the teams included all 6 at one location, 5 at one location and 1 at the other, 4 at one location and 2 at the other, and 3 at each location.

Contrary to conventional wisdom the configuration with one isolated member and five members at the other location performed better even than the completely co-located team. Apparently the isolated member provides a focus for the other members of the team to schedule and coordinate communications. The authors speculate that a 'novelty effect' could be in play or that "one person wouldn’t be a threat to the rest of the team."

The worst configuration was that with two members separated from the other four. The two bonded with each other but not with the rest of the team.

MIT Sloan Management Review.

PS. As an independent consultant who frequently operates as an isolated individual in a distant team I found this study particularly encouraging.

Light My Fire

 Every kid has that moment of excitement when he focuses the sun’s rays through a magnifying glass on a bit of leaf and it starts to smolder. Imagine the exhilaration of the scientists at Lawrence Livermore's National Ignition Facility (NIF) each time all of its 192 ultra-powerful laser beams are focused on a tiny deuterium-tritium filled capsule causing it to implode. In one such experiment recently, the yield of neutrons reached nearly a thousand million million neutrons (1 x 10¹⁵) setting a new record for neutron energy yield at the NIF.

For the first time "the yield was significantly greater than the energy deposited in the hot spot by the implosion," said Ed Moses, principal associate director for NIF and Photon Science.

Establishing a self-sustaining fusion reaction – ignition - is now one step closer. These experiments underpin the primary mission of NIF to provide experimental insight and data for the stewardship of the nation’s nuclear weapons stockpile. Demonstrating ignition is the first step required to permit fusion energy to be used for civilian energy production and for weapons validation that avoids underground testing.

Developing fusion energy could be a revolutionary moment in human history. Today’s nuclear power plants run on fission, not fusion. Fission reactions produce large volumes of radioactive by-products and wastes that remain hazardous for thousands of years, creating a storage problem. Fusion is preferred over fission since it produces almost no radioactivity, releases more energy per gram of fuel, and is a self-terminating reaction, so fusion reactors can’t melt down like fission reactors have. Also, since the energy release per gram of fuel is so great, only about 200 kg of fuel is needed to supply the energy equivalent of all the oil consumed in the US each day. Commercial applications are still ‘decades away’ according to most observers, however.
