More than 8.3 billion metric tonnes of plastic has been produced in the last six decades.

However, recycling plastic can be difficult as the most common process involves melting and reworking the material.

A new process developed by the University of California can turn polyethylene into useful smaller molecules.

If you thought those flimsy disposable plastic grocery bags represented most of our plastic waste problem, think again. The volume of plastic the world throws away every year could rebuild the Ming Dynasty’s Great Wall of China – about 3,700 miles long.

IQ rates are dropping in many developed countries and that doesn’t bode well for humanity

B48C81E6-D274-41A8-9923-DBD0E8F5D5C2

 IQ rates are dropping and we’re too stupid to figure out why.

 An intelligence crisis could undermine our problem-solving capacities and dim the prospects of the global economy.

IQ rates are falling across Western Europe, and experts are scratching their heads as to why.May 22, 2019, 2:31 AM MDT

People are getting dumber. That’s not a judgment; it’s a global fact. In a host of leading nations, IQ scores have started to decline.

Though there are legitimate questions about the relationship between IQ and intelligence, and broad recognition that success depends as much on other virtues like grit, IQ tests in use throughout the world today really do seem to capture something meaningful and durable. Decades of research have shown that individual IQ scores predict things such as educational achievement and longevity. More broadly, the average IQ score of a country is linked to economic growth and scientific innovation.

An AI analysis of 500,000 studies shows how we can end world hunger

C1C8AB54-1014-44FD-A68A-59D8302252BC

An Indian farmer dries harvested rice from a paddy field in Assam.

Ending hunger is one of the top priorities of the United Nations this decade. Yet the world appears to be backsliding, with an uptick of 60 million people experiencing hunger in the last five years to an estimated 690 million worldwide.

To help turn this trend around, a team of 70 researchers published a landmark series of eight studies in Nature Food, Nature Plants, and Nature Sustainability on Monday. The scientists turned to machine learning to comb 500,000 studies and white papers chronicling the world’s food system. The results show that there are routes to address world hunger this decade, but also that there are also huge gaps in knowledge we need to fill to ensure those routes are equitable and don’t destroy the biosphere.

Will we ever trust crowds again?

4ED078A3-E1EF-4B24-8CC9-17601841D438

If socializing makes you cringe, you’re not alone. Scientists say the pandemic is re-shaping our senses of fear and disgust, and it’s unclear how long the change will last.

WATCHING A RERUN of the 1990s sitcom Seinfeld gave me the first inkling that COVID-19 might be rearranging my mind for the long term. On the screen, the characters sat across the table from each other at Monk’s Café. Kramer flopped into the frame, draping his arm around another occupied chair. As his arm touched another person, I physically recoiled.

By then, my hometown of New Orleans was a few weeks into the pandemic, and I was already stepping off the curb whenever a stranger approached. If someone slipped by my paranoia and caught me unaware on the sidewalk, I held my breath and rolled my eyes as they barged past. Those behaviors felt natural, even though by mid-March, scientists were already pointing out the low risk of coronavirus transmission in the outdoors. All of my friends reported feeling something similar, and one told me that she had to turn off the TV if a subway scene came on. We’re not alone. Even as some states begin to reopen, most Americans—regardless of political affiliation—say that they’re uncomfortable going into crowded situations, indoors and out, according to a recent Morning Consult poll.

Neuroscientists and psychologists propose that people aren’t cringing around strangers and crowds because of pre-existing senses of fear or disgust. Instead, many in society are simultaneously learning a new emotional experience.

New super-enzyme eats plastic bottles six times faster

117F340C-2505-41E5-AB56-E5A2B9401797

Breakthrough that builds on plastic-eating bugs first discovered by Japan in 2016 promises to enable full recycling

A super-enzyme that degrades plastic bottles six times faster than before has been created by scientists and could be used for recycling within a year or two.

The super-enzyme, derived from bacteria that naturally evolved the ability to eat plastic, enables the full recycling of the bottles. Scientists believe combining it with enzymes that break down cotton could also allow mixed-fabric clothing to be recycled. Today, millions of tonnes of such clothing is either dumped in landfill or incinerated.

Plastic pollution has contaminated the whole planet, from the Arctic to the deepest oceans, and people are now known to consume and breathe microplastic particles. It is currently very difficult to break down plastic bottles into their chemical constituents in order to make new ones from old, meaning more new plastic is being created from oil each year.

A new startup is recruiting gig workers to help landlords evict people from their homes, calling it the fastest-growing moneymaking gig because of COVID-19

E1C811C5-7313-4476-BF8B-A82F2F3EF0DF

A new startup is recruiting gig workers to help landlords evict people who can’t afford to pay rent during the COVID-19 pandemic.

Civvl, which Motherboard described as “Uber, but for evicting people,” has posted job listings across the US that encourage gig workers to join the app and work as eviction crew members.

Civvl notes that landlords are looking to hire workers to evict tenants who can’t afford to pay rent, advertising the gig as the “FASTEST GROWING MONEY MAKING GIG DUE TO COVID-19.”

The CDC is imposing a moratorium on all evictions across the US, but Civvl’s terms appear to pass on responsibility to landlords to ensure that evictions carried out through the startup are legal.

‘We were shocked’: RAND study uncovers massive income shift to the top 1%

619FCEAA-CB5B-4A52-8D56-1C8D33922D68

The median worker should be making as much as $102,000 annually—if some $2.5 trillion wasn’t being “reverse distributed” every year away from the working class.

Just how far has the working class been left behind by the winner-take-all economy? A new analysis by the RAND Corporation examines what rising inequality has cost Americans in lost income—and the results are stunning.

A full-time worker whose taxable income is at the median—with half the population making more and half making less—now pulls in about $50,000 a year. Yet had the fruits of the nation’s economic output been shared over the past 45 years as broadly as they were from the end of World War II until the early 1970s, that worker would instead be making $92,000 to $102,000. (The exact figures vary slightly depending on how inflation is calculated.)

The findings, which land amid a global pandemic, help to illuminate the paradoxes of an economy in which so-called essential workers are struggling to make ends meet while the rich keep getting richer.

World wildlife plummets more than two-thirds in 50 years: index

 68CF5193-CC92-4A77-B5F2-ABD67D7141A4

Graphic outlining the environmental degredation of the oceans caused by human activity.

Global animal, bird and fish populations have plummeted more than two-thirds in less than 50 years due to rampant over-consumption, experts said Thursday in a stark warning to save nature in order to save ourselves.

Human activity has severely degraded three quarters of all land and 40 percent of Earth’s oceans, and our quickening destruction of nature is likely to have untold consequences on our health and livelihoods.

The Living Planet Index, which tracks more than 4,000 species of vertebrates, warned that increasing deforestation and agricultural expansion were the key drivers behind a 68 percent average decline in populations between 1970 and 2016.

It warned that continued natural habitat loss increased the risk of future pandemics as humans expand their presence into ever closer contact with wild animals.

This image depicts the exterior of the CDC’s “Tom Harkin Global Communications Center” located on the organization’s Roybal Campus in Atlanta, Georgia.

 ATLANTA, Ga. (WEYI) – The Centers for Disease Control released information showing how many people who died from COVID-19 had comorbidities or underlying conditions as they are sometimes referred to by doctors.

According to the CDC, comorbidity is defined as: ” more than one disease or condition is present in the same person at the same time. Conditions described as comorbidities are often chronic or long-term conditions. Other names to describe comorbid conditions are coexisting or co-occurring conditions and sometimes also “multimorbidity” or “multiple chronic conditions.”

Comorbidity and underlying conditions can both be used to describe conditions that exist in one person at the same time. These can also contribute to a persons death who has been diagnosed with COVID-19.

The Economic Model of Higher Education Was Already Broken. Here’s Why the Pandemic May Destroy It for Good

Virus Outbreak-Ohio Schools

Logan Armstrong, a Cincinnati junior, works while sitting inside a painted circle on the lawn of the Oval during the first day of fall classes on at Ohio State University on Aug. 25, 2020.

Karabell is an author, investor, and commentator. He is the president of River Twice Research. His forthcoming book is Inside Money: Brown Brothers Harriman and the American Way of Power.

With the fall semester upon us, colleges and universities unveiled their plans for students—and many are just as quickly upending those plans. The University of North Carolina and Notre Dame recently announced they were changing their on campus plans as COVID-19 cases spiked. Many other universities are sure to follow. Already, universities ranging from Syracuse to Ohio State are suspending hundreds of students for violating social distancing rules, while COVID-19 outbreaks are on the rise on campuses such as the University of Alabama. While there is considerable variety in the actual plans, ranging from mostly in-person to all virtual, they all share one imperative: to maintain an economic model that is as imperiled by the pandemic as the hardest hit service industries.

The world’s growing concrete coasts

66CB0AD4-3758-4D20-9331-AC30551AEE20

The world’s coastlines are turning to concrete, at a huge cost to wildlife and the climate. But new technologies may offer a way to shore up coasts while benefiting biodiversity.

It’s one of the most impressive feats in modern engineering, and crossing the world’s longest sea bridge – the 55km (34 miles) Hong Kong-Zhuhai-Macau bridge, which opened in October 2018 at a cost of $20bn (£15.9bn) – certainly has its benefits. But impressive as it appears, this mammoth construction project, like so many others, has come at a cost.

No less than one million tonnes of concrete were used in the eight years it took to build the bridge. It was this concrete that invaded the habitat of the critically endangered pink dolphin, and is thought to be the reason that dead dolphins washed up on nearby shores while the population near the bridge plummeted by 60%. Of course, dolphins weren’t the only victims – habitats are destroyed and countless other marine species are affected when large amounts of concrete are poured into the ocean.

Destruction of this kind is often the cost of using concrete – the most widely used manmade material on Earth. With three tonnes per year used for every person in the world, there are few parts of the planet that concrete hasn’t reached. The production of concrete is also a huge emitter of CO2. At least 8% of humanity’s carbon footprint comes from the concrete industry, mostly from the production of cement – one of concrete’s principal components. The cement industry generates around 2.8 billion tonnes of CO2 per year – more than any country other than China or the US.

Reimagining industrial supply chains

 12C5438E-0841-465F-8AC3-4C9666CD91D5

For organizations that understand the vulnerabilities in industrial supply chains, there is an opportunity to prepare for future shocks and build resilience without hurting efficiency.

In recent months, structural supply-chain fragility has been catapulted to the top of the news cycle as the ongoing repercussions of the COVID-19 pandemic echo around the world. Government-imposed orders to stay at home, international and domestic travel restrictions, and the need for physical distancing have stretched supply chains and laid bare the key bottlenecks in products’ value chains. Shortages have occurred in areas ranging from basic grocery items to electronic components.

The current pandemic is the type of event that is only likely to occur once in a lifetime. In recent years, however, supply-chain risk management has become more of a pressing issue for CEOs across industries. Vulnerabilities have been exposed by trade tensions, natural disasters, and other geo-economic disruptions.

The complexity of global industrial supply chains exponentially increases their risk. On average, an auto manufacturer has around 250 tier-one suppliers, but the number proliferates to 18,000 across the full value chain. Aerospace manufacturers have an average of 200 tier-one suppliers and 12,000 across all tiers. Finally, technology companies have an average of 125 suppliers in their tier-one group and more than 7,000 across all tiers.

Companies that cannot successfully manage those complex and, at times, opaque supply chains are at high risk, especially if they cannot mitigate the risk of increasing disruptions. Even a short disruption of 30 days or fewer can put 3 to 5 percent of EBITDA margin at stake. Recent research from the McKinsey Global Institute (MGI) has found that as much as 45 percent of one year’s EBITDA1 can be lost each decade because of disruptions.
