Improving sustainable practices
In its effort to reduce risks of disruptions while still managing to be sustainable and efficient in operations, some supply chain leaders are at a crossroads. This predicament is understandable since, as Ian Lefshitz, a contributor to Supply Chain Executive, worded it, “While there are obvious long-term benefits to more sustainable practices, a major challenge for corporations and procurement professionals in particular is ensuring that the entire supply chain meets established standards.”

Three years ago, Dustin Fedako attended the US Composting Council’s annual conference. As founder of Compost Pedallers, a bike-powered compost recycling program in Austin, Texas, Fedako didn’t know what to expect from the conference, which is geared toward the industrial composting model. He just wanted to “sponge up as much as he could.” He learned a lot and he also spent a lot of time explaining what community composting is.

A wearable device promises to help steady hand tremors by using an old technology—gyroscopes.

 

When he was a 24-year-old medical student living in London, Faii Ong was assigned to care for a 103-year-old patient who suffered from Parkinson’s, the progressive neurological condition that affects a person’s ease of movement. After watching her struggle to eat a bowl of soup, Ong asked another nurse what more could be done to help the woman. “There’s nothing,” he was grimly told.

Ong, now 26, didn’t accept the answer. He began to search for a solution that might offset the tremulous symptoms of Parkinson’s, a disease that affects one in 500 people, not through drugs but physics. After evaluating the use of elastic bands, weights, springs, hydraulics, and even soft robotics, Ong settled on a simpler solution, one that he recognized from childhood toys. “Mechanical gyroscopes are like spinning tops: they always try to stay upright by conserving angular momentum,” he explains. “My idea was to use gyroscopes to instantaneously and proportionally resist a person’s hand movement, thereby dampening any tremors in the wearer’s hand.”

Together with a number of other students from Imperial College London, Ong worked in the university’s prototyping laboratory to run numerous tests. An early prototype of a device, called GyroGlove, proved his instinct correct. Patients report that wearing the GyroGlove, which Ong believes to be the first wearable treatment solution for hand tremors, is like plunging your hand into thick syrup, where movement is free but simultaneously slowed. In benchtop tests, the team found the glove reduces tremors by up to 90 percent.

GyroGlove’s design is simple. It uses a miniature, dynamically adjustable gyroscope, which sits on the back of the hand, within a plastic casing attached to the glove’s material. When the device is switched on, the battery-powered gyroscope whirs to life. Its orientation is adjusted by a precession hinge and turntable, both controlled by a small circuit board, thereby pushing back against the wearer’s movements as the gyroscope tries to right itself.

While the initial prototypes of the device still require refinements to size and noise, Alison McGregor, professor of musculoskeletal biodynamics at Imperial College, who has been a mentor to the team, says the device “holds great promise and could have a significant impact on users’ quality of life.” Helen Matthews of the Cure Parkinson’s Trust agrees: “GyroGlove will make everyday tasks such as using a computer, writing, cooking, and driving possible for sufferers,” she says.

There is a lot of plastic in the world’s oceans.

It coagulates into great floating “garbage patches” that cover large swaths of the Pacific. It washes up on urban beaches and remote islands, tossed about in the waves and transported across incredible distances before arriving, unwanted, back on land. It has wound up in the stomachs of more than half the world’s sea turtles and nearly all of its marine birds, studies say. And if it was bagged up and arranged across all of the world’s shorelines, we could build a veritable plastic barricade between ourselves and the sea.

But that quantity pales in comparison with the amount that the World Economic Forum expects will be floating into the oceans by the middle of the century.

If we keep producing (and failing to properly dispose of) plastics at predicted rates, plastics in the ocean will outweigh fish pound for pound in 2050, the nonprofit foundation said in a report Tuesday.

A common criticism of a total transition to wind, water and solar power is that the US electrical grid can’t affordably store enough standby electricity to keep the system stable. Now a researcher proposes an underground solution to that problem.

A new study shows that wind, water and solar generators can theoretically result in a reliable, affordable national grid when the generators are combined with inexpensive storage.

A new paradigm for the development of photo-bioelectrochemical cells has been reported in the journal Nature Energy by researchers from The Hebrew University of Jerusalem, in Israel, and the University of Bochum, in Germany.

The design of photo-bioelectrochemical cells based on native photosynthetic reaction is attracting substantial recent interest as a means for the conversion of solar light energy into electrical power.

there is a clearly visible trend of public companies (82%) to publish sustainability reports in order to disclose information and be transparent about their sustainability performance. What is also interesting is that there is a growing trend for Small-Medium Enterprises to publish sustainability reports in order to increase their transparency, attract customers and grow their business.

Since 2011, French photographer Laurent Kronental has been working on an ongoing series documenting life on the edge of Paris in the “grands ensembles.” These monumental housing projects were built between the 1950s and the 1980s on the outskirts of major French cities as answers to a dearth of housing and an influx of foreign migrants. Aging monolithic concrete structures with an almost alien presence in the French landscape, they are a far cry from the Haussmannian apartment blocks that dominate central Paris and the world’s collective imagination about how the French live.

 

Kronental said in an artist’s statement that he is “fascinated by these projects’ ambitious and dated modernistic features” that “are today often stigmatized by the media and marginalized by public opinion.” He hopes that his images provide “sharp contrast with these cliché views” and celebrate the often overlooked “urban veterans who have aged there.”
