Plastic pollution in the world’s oceans may have an impact of $ 2.5 billion, adversely affecting “almost all marine ecosystem services”, including areas such as fishing, recreation and heritage. But a breakthrough from researchers at Berkeley Lab may be the solution the planet needs for this eye-opening problem – recyclable plastic. The study, published in Nature Chemistry, describes how the researchers could find a new way to assemble plastic and reuse them “to new materials of any color, shape or shape.” “Most plastic materials were never made to be recycled,” says senior author Peter Christensen, a postdoctoral researcher at Berkeley Lab’s molecular foundry, in the statement. “But we have discovered a new way to assemble plastic that takes into account recycling from a molecular perspective.”

Known as poly (diketoenamine) or PDK, the new type of plastic material can help stop the tide of plastic as the PDK forms can be reversed via a simple acid bath, the researchers believe. “Poly (diketoenamine) s” clicks “together from a variety of triketones and aromatic or aliphatic amines, giving only water as a by-product,” abstraction of the abstract reads. “Recycled monomers can be transformed into the same polymer formulation without loss of performance, as well as other polymer formulations with differentiated properties. The simplicity with which poly (diketoenamine) s can be made, used, recycled and reused without losing value points to new directions in designing durable polymers with minimal environmental impact. ” Unlike conventional plastic, monomers of PDK plastic could simply be recovered and freed from any added additives simply by dumping the material in a very acidic solution.

Over the last decade, journalists have held up Germany’s renewables energy transition, the Energiewende, as an environmental model for the world.
Is anyone free to decide her own destiny? Or is the course of her life determined by prior events? Since so many of our decisions operate under constraints of various kinds — the imperative to do something or be somewhere at a fixed time — is free will an illusion? The question takes on added significance given the overwhelming economic imperative to survive in a vicious world. So much of what we desire nowadays is not so much “unthinkable” — we can always dream — as practically impossible. What hope is there of recovering possibility from a world in which the future has become as predictable as the next rent day?
Burnout — work-related stress resulting in emotional and physical exhaustion — remains an expected rite of passage for many professions. However, the medical community has begun to place more emphasis on reducing burnout — and science academia would do well to learn from it. Despite the differences between medical and scientific training, stress is a common denominator for students in both fields. For example,
Maybe podcasting would be more interesting if it were an instrument of fascism, or terrorism. ISIS knows better: they don’t make podcasts, they make YouTube videos. Talk radio can still control the listener’s emotional response, but no one feels threatened by the infinitely banal podcast. Instead of emotion or camaraderie, what podcasts produce is chumminess
He studied theology and philosophy, completing his doctoral studies on happiness in the ethics of Aristotle. He became a teaching professor at St Michael’s College in Toronto.
The governing elites of ancient and medieval Europe were not greatly hospitable to humor. From the earliest times, laughter seems to have been a class affair, with a firm distinction enforced between civilized amusement and vulgar cackling. Aristotle insists on the difference between the humor of well-bred and low-bred types in the

For decades now physicists have been struggling to reconcile two great ideas from a century ago: general relativity and quantum mechanics. We don’t yet know the final answer, but the journey has taken us to some amazing places. A leader in this quest has been Leonard Susskind, who has helped illuminate some of the most mind-blowing ideas in quantum gravity: the holographic principle, the string theory landscape, black-hole complementarity, and others. He has also become celebrated as a writer, speaker, and expositor of mind-blowing ideas. We talk about black holes, quantum mechanics, and the most exciting new directions in quantum gravity.
The opening frame of “What’s My Name” shows Ali explaining that should his story ever be told, he wants it done in full. So, there are no talking heads or narration, because who better to tell such a remarkable, revolutionary story than Muhammad Ali himself? His interviews and words guide us through his life, from early childhood until his final days, as he endures the bodily constraints of Parkinson’s disease. Ali’s famous, rhythmic one-liners, like “float like a butterfly, sting like a bee,” are accompanied by his critical analysis about race, white supremacy and his politics, which are global.
Trilling rather disliked the label “literary critic” and was pleased when Étienne Gilson suggested, in 1955, that he was not one. (Just what Gilson proposed him to be is not made clear.) All the same, twenty years after the Gilson exchange, Trilling would write to someone, who had sent him some offprints, to aver that he should “best refer to me as a critic of literature.” He did not much care for the New Criticism of Allen Tate, William Empson, and Cleanth Brooks, calling it snide and restrictive. Leon Edel, more a literary historian than a critic to be sure, he thought dull-witted (“a very stupid man”). One would not expect the life of a literary critic to be full of high adventure and derring-do, and the composite portrait of a critic’s life as painted in Trilling’s letters appears a largely unruffled if not a completely serene one. He married young and stay married to the same woman for his entire life. If there were any occasions of extramarital desire, much less action, they are not even intimated here. There is only a single rather explicit letter, to his wife, Diana, in which he talks about sex, and he never once swears and rarely uses slang. (When he writes in a letter to Norman Mailer that sex should be a subject for novelists for “ten, maybe twelve years; then everybody shut up,” it is a bit of a shock.)
There is a way in which all of Bette Howland’s characters seem like visitors from a parallel universe, where they are free rather than confined. This is the eponymous visitor in the opening story of this collection: “I was catching on at last. The bad roads, the crash, the minor injury. This petty bureaucrat. This place. Sir? I’m dead? Is that it? I’m dead? … That’s what they all want to know! he said. But that’s the whole show! I can’t give that away, can I?” An uncle’s young wife is “a big handsome Southern girl, rawboned, rock jawed, her pale head dropped over her knitting. Peculiarly pale; translucent, like rock candy, and almost as brittle.” It is as if they step into a room accompanied by their own lighting. “ ‘When are you going to get married?’ Uncle Rudy asked, towering over me.” Imagination is what she calls what she does with them, imaginative selection from the panoply of life. “He’s a scofflaw. He’ll go out of his way to park illegally. He’ll drive around the block looking for a No Parking sign or a nice little fire hydrant.” Reading the prose brings a Bette I’d forgotten—a glass of Scotch, how she threw back her head and uproariously laughed. Ah, yes; here’s the one with verve, the woman in the fedora photo.
WASHINGTON — Humans are transforming Earth’s natural landscapes so dramatically that as many as one million plant and animal species are now at risk of extinction, posing a dire threat to ecosystems that people all over the world depend on for their survival, a sweeping new United Nations assessment has concluded. The 1,500-page report, compiled by hundreds of international experts and based on thousands of scientific studies, is the most exhaustive look yet at the decline in biodiversity across the globe and the dangers that creates for human civilization.

When I was laid off in 2015, I told people about it the way any good millennial would: By tweeting it. My hope was that someone on the fringes of my social sphere would point me to potential opportunities. To my surprise, the gambit worked. Shortly after my public plea for employment, a friend of a friend sent me a Facebook message alerting me to an opening in her department. Three rounds of interviews later, this acquaintance was my boss. (She’s now one of my closest friends).
