Getting microbes to eat plastic is a frequently touted solution to our growing waste problem, but making the approach practical is tricky. A new technique that impregnates plastic with the spores of plastic-eating bacteria could make the idea a reality. The impact of plastic waste on the environment and our health has gained increasing attention in recent years. The latest round of UN talks aiming for a global treaty to end plastic pollution just concluded in Ottawa, Canada earlier this week, though considerable disagreements remain.
Recycling will inevitably be a crucial ingredient in any plan to deal with the problem. But a 2022 report from the Organization for Economic Cooperation and Development found only 9 percent of plastic waste ever gets recycled. That’s partly due to the fact that existing recycling approaches are energy intensive and time consuming. This has spurred a search for new approaches, and one of the most promising is the use of bacteria to break down plastics, either by rendering them harmless or using them to produce building blocks that can be repurposed into other valuable materials and chemicals. The main problem with the approach is making sure plastic waste ends up in the same place as these plastic-loving bacteria.
Now, researchers have come up with an ingenious solution: embed microbes in plastic during the manufacturing process. Not only did the approach result in 93 percent of the plastic biodegrading within five months, but it even increased the strength and stretchability of the material. “What’s remarkable is that our material breaks down even without the presence of additional microbes,” project co-leader Jon Pokorski from the University of California San Diego said in a press release. “Chances are, most of these plastics will likely not end up in microbially rich composting facilities. So this ability to self-degrade in a microbe-free environment makes our technology more versatile.”

Whether mobilizing for war or (re)constructing advanced manufacturing capabilities in peacetime, success turns on the functioning of complex supply chains. But this truth was long forgotten – or at least under-appreciated. Not until recent supply-chain shocks did academics, policymakers, and others start paying more attention to the complicated, barely studied “meso” (middle) domain between microeconomics and macroeconomics.
For thousands of years, humankind has fancied itself the apex of creation and the dominant force in the world. Yet humans are now gripped by the fear that yet another species of our own creation—artificially intelligent machines—will presently displace us from our position of unchallenged domination, perhaps even enslaving us.

Language as self, language learning as magic, the mortifications of the flesh: these themes run through The Centre, a debut novel by British-Pakistani writer and translator Ayesha Manazir Siddiqi. Its narrator, Anisa, is a Pakistani translator of Urdu living in London, grappling with tensions of her immigrant identity and cosmopolitan desires. Yes, she had achieved her dream of moving to England but dislikes the cold and the myriad forms of casual racism she encounters. She complains that living outside of Pakistan has tainted her Urdu (her mother tongue) with Hindi words, and she resents the fact that she uses Urdu merely to translate Bollywood film subtitles — as opposed to the great literature she admires. To top it off, her other language, French, is mediocre. « Not like French-person French, » she complains to a friend.
It is one of the recurring plotlines in the psychodrama of U.S. politics: A talented and charismatic young reformer goes to Washington, is hailed for taking on a corrupt and self-satisfied establishment, but in the end is nearly undone by inexperience, naiveté and unbending idealism. The latest “Mr. Smith” to hit the capital is Lina Khan, the crusading chair of the Federal Trade Commission who, at the age of 35, has become the wonky cult hero and legal wunderkind of a new progressive movement determined to break the economic and political power of Big Business and Big Tech.
It’s been 14 years since Goldman Sachs was vilified as a “vampire squid” by Matt Taibbi in Rolling Stone. “Organized greed always defeats disorganized democracy,” he concluded then. Goldman has since experienced some hard times, tarred by scandal (the
As I’ve been researching and writing Boundless 2.0, I’ve found myself reevaluating many of the health and fitness strategies that I previously endorsed.
Imagine you had a friend who gave different answers to the same question, depending on how you asked it. “What’s the capital of Peru?” would get one answer, and “Is Lima the capital of Peru?” would get another. You’d probably be a little worried about your friend’s mental faculties, and you’d almost certainly find it hard to trust any answer they gave.
