Wool: Old Wine in New Bottles

By Timothy C. Mack

Wool is one of man’s oldest materials. It’s been in use for at least 3,400 years, but it was not effectively utilized until selective breeding reduced the hard outer layer (known as kemp) that protects the usable fleece. While the industrial uses for this material have grown over the years, the potential now is rapidly expanding. Wool is both water retentive and water repellant, fire resistant up to 1,382 degrees Fahrenheit (and does not melt, unlike synthetics). It’s being explored for use in silt and erosion control, military blast protection, and high-impact management in sports, and it even has been effective for soundproofing.

In an ecological context, wool is a natural, renewable, and sustainable material, as well as being nonallergenic, nonirritating, and mold-resistant. It only requires a fraction of the production and energy costs of manmade materials put to similar uses.

Wool can extinguish fire because of its high nitrogen content and an oxygen combustion level higher than ambient air. It is now being added to brick clay to increase strength by 37 percent. In the environmental remediation arena it has been used to clean up oil spills, and woolen coverings have been used to protect birds from petroleum poisoning.

Finally, the natural oil in wool (lanolin) is being used in pharmaceuticals, cosmetics, inks, tapes, motor oils, and auto lubricants. And to wrap up the theme of “miracle material,” some research suggests that a strand of wool appears to be stronger than a steel strand of same diameter.

Note: The take-away lesson here is that past or historical assumptions may be limiting potential rethinking of material utility and context. Recognizing such assumptions is especially appropriate where present markets are dwindling.

The Challenges of a Rising China


China is rising as a global economic power, but “it’s also a developing country with a postcolonial chip on its shoulder,” Thomas J. Christensen, director of the China and the World Program at Princeton University, said at a June 25 Brookings Institution forum for his new book, The China Challenge: Shaping the Choices of a Rising Power.

Noting that China’s military has grown faster than its economy, Christensen said security has become a major challenge that the U.S. diplomatic corps is not particularly well prepared to deal with. China’s military power is not yet a match for the United States, but it is potentially capable of creating disruptions for many U.S. allies and strategic partners in China’s neighborhood.

Global problems cannot be solved without China’s participation, said Christensen, who was deputy assistant secretary of state for East Asian and Pacific affairs from 2006 to 2008. As a developing country (with approximately the same per capita GDP as Ecuador), China has no social safety net of its own and is neither prepared nor motivated to assist places like Greece.

Since the global financial crisis of 2008, “China is stronger overseas and weaker, less secure, at home,” Christensen said. “That changes how they behave.” Influencing China’s choices and actions on global issues, such as climate change or North Korea’s nuclear proliferation, will require a better understanding of its mind-set.

“Accept the Chinese’ strong nationalism, and praise China’s efforts in order to encourage its cooperation,” Christensen said. He recommended that the United States invite China to solve problems like North Korea; if they don’t step up, then turn to others. “That gets their attention and shows them it’s in their interest.”

Children’s Fitness Levels Are Falling Fast


The least-fit kid 15 years ago could be among the fittest kids today, according to University of Essex researcher Gavin Sandercock. While obesity rates are down, as measured by body mass index (BMI), children ages 10–11 today are slower, weaker, and have less stamina than their counterparts in 1998.

Less than 5 percent of the 300 schoolchildren participating in the study were rated as obese, which suggested that today’s slimmer cohorts could perform better on fitness tests. This was not the case, Sandercock reports.

“Simply put, if you weigh less it is easier to run and turn so you should do better on our test,” Sandercock stated in a press release. “But despite finding a lower average BMI in the children measured in 2014 than in 2008 we found the children still couldn’t run as fast, showing they had even lower cardiorespiratory fitness.”

Like obesity, this lack of physical fitness is a symptom of inactivity, according to Sandercock. He recommends new measures that go beyond BMI indicators to assess children’s “physical literacy,” including such fundamental movement skills such as running, hopping, throwing, catching, and jumping.

Earthquake Prediction in Developing Countries


Geological evidence from the past could provide an affordable method of predicting earthquakes in developing countries without access to extensive seismic monitoring.

Researchers at Australia’s James Cook University found evidence of land deformation and fluidization (quicksand-like displacement) in the ground at the site of a large Tanzanian earthquake 25,000 years ago. The amount of upward displacement was unprecedented in a continental setting, according to lead researcher Hannah Hilbert-Wolf.

“This could be a major concern for the growing urban population of East Africa, which has similar tectonic settings and surface conditions,” she said in a press statement.

Insights from the rock record on the timing and frequency of past geological events could enable researchers to predict how the ground will behave in future seismic events.

“We can now use this to evaluate how the ground would deform in a modern earthquake,” according to supervising researcher Eric Roberts. “This is important because the approach is inexpensive and can be used to model how structures might be affected by future events, providing a valuable tool in hazard assessment.”

As human populations grow, such powerful shakeups as the 1910 African earthquake will affect far more lives. Tanzania’s population in 1910 was 7.5 million, but by 2050 it is predicted to reach 130 million people living primarily in urban settings more susceptible to damage.

Sesame: The Seed of the Future?


From tahini and falafel in the Middle East to hamburger buns and bagels in New York, sesame seeds are popular around the world. The seeds are rich in protein, minerals, and healthy oils, but the crop is difficult to harvest. Yields are low, with a high percentage of seeds unsuitable for consumption.

To boost their agricultural viability, researcher Zvi Peleg of the Hebrew University of Jerusalem screened more than 100,000 sesame seed variants. He developed a new cultivar that promises higher yields and better suitability for sustainable agriculture when used in rotation with other cereal crops.

Global sesame production is 4.4 million tons a year, but the new seed could contribute to a projected 5 to 10 percent growth value annually, Peleg suggests.

“The increase in global demand for sesame products as a health food has turned this highly domestic consumption item into an important export commodity for Israel,” Peleg said in a press statement.

Harvesting Energy on Mars


A major technological hurdle to colonizing Mars is providing a sustainable source of energy for travelers and inhabitants. Researchers at Northumbria University are developing an engine that can harvest energy from carbon dioxide, which is apparently abundant on Mars in the form of dry ice. The breakthrough also means that a ticket to Mars need not be one way, according to scientists.

The technique, described in the journal Nature Communications, exploits a phenomenon known as the Leidenfrost effect, which produces energy when a liquid comes in contact with a surface much hotter than the liquid’s boiling point. With solid carbon dioxide (dry ice), the Leidenfrost effect creates a vapor, which the Northumbria team believes can be captured to power an engine with significantly less friction.

“One thing is certain, our future on other planets depends on our ability to adapt our knowledge to the constraints imposed by strange worlds, and to devise creative ways to exploit natural resources that do not naturally occur here on Earth,” said co-author Rodrigo Ledesma-Aguilar in a press statement.

Deforestation and Species Loss in the Amazon


A third of the Amazon is approaching a tipping point in deforestation that will accelerate species loss. By 2030, these endangered areas could lose 31 percent to 44 percent of species, predicts a team of Cambridge University researchers.


Historically, just one or two species is lost for every 10 percent loss of forest coverage; however, when an area dips below a threshold of 43 percent of forest coverage, species loss accelerates to two to eight species per 10 percent forest loss.

Pressure on land use comes largely from agriculture, as farmers work to meet the demands of growing (and increasingly affluent) human populations. In Brazil, individual landowners are required to retain 80% forest cover, but this is rarely achieved, according to the researchers. A more successful approach might be to consider entire landscapes rather than individual farms, and to promote practices that stop deforestation above the threshold.

The research supports a new approach to environmental legislation in Brazil and the tropics, said study leader Jose Manuel Ochoa-Quintero in a press statement. “We need to move from thinking in terms of compliance at a farm scale to compliance at a landscape scale if we are to save as many species as we can from extinction,” he concluded.

Can Customers Be Too Engaged?


Increasing audience engagement has long been a mantra in brand promotion, but a new study in the Journal of Consumer Research suggests that some audience members may be too engaged for a brand’s good.

Using the popular American reality TV series America’s Next Top Model as a case study, researchers Marie-Agnès Parmentier (HEC Montréal) and Eileen Fischer (York University) examined how social media enabled and encouraged fans to interact with the show and with other fans. Though the show encouraged this engagement, its consequences were often out of the producers’ control.

Thanks to their engagement, many fans felt encouraged to persistently and passionately offer their advice regarding things they didn’t like about the show (change of format, new judges, etc.). The unintended consequence was to contribute to a negative image of the show among other fans. The researchers conclude that the most enthusiastic fans may have thus inadvertently contributed to the show’s declining popularity.

The lesson for brands: Beware of what you wish for. “Ironically, fans may contribute to the destabilization of a brand even as they are trying to help prevent this,” write Parmentier and Fischer. “While fans can be conducive to brand value creation or co-creation, they can equally contribute to value co-destruction.”

Jumping Technology Categories: Report from Timothy C. Mack


In Silicon Valley, the blessing (or curse) of vast disposable resources appears to be leading a number of companies out of the arena of computer software and hardware development into such terra incognita as Google’s self-driving, electric-powered car.


Google already has five years of R&D invested in this self-driving car project. However, how well would Google find its way in an entirely new marketplace with technology of a distinctly new level? As Mashable writer Lance Ulanoff notes, there are as many as 6,000 parts in an automobile, and there is a much higher standard for drivability and driver safety than is required for software and hardware.

The price points involved in such a quantum shift are quite intimidating, considering both the overhead investment per unit and the volume of units that would need to be sold to make the numbers work.

As I have observed elsewhere, the liability issues for self-driving cars are likely to take years and maybe even decades to sort out. Unintended consequences arise from even small shifts in direction. The outcomes of such an adventure are difficult to estimate, but they are likely to be substantial and messy. Read more
