Is the universe open-ended?

Is the universe open-ended?

Caleb Scharf writes: One of my favorite albeit heavily paraphrased quotes from Albert Einstein is his assertion that the most incomprehensible thing about the universe is that it is comprehensible. (What he actually said, in his 1936 work “Physics and Reality,” is more longwinded, and includes a digression into Immanuel Kant and the meaning of “comprehensibility,” but he does write “… the eternal mystery of the world is its comprehensibility.”) In truth, this statement holds back a little. The greater…

Why Facebook really, really doesn’t want to discourage extremism

Why Facebook really, really doesn’t want to discourage extremism

Steve Rathje, Jay Van Bavel and Sander van der Linden write: Our findings may reflect the fact that, more and more, political identities are driven by hating the opposition more than loving one’s own party. Out-party hate has been increasing steadily over the past few decades, researchers find, and is at the highest level seen in 40 years. Out-group hate is also more strongly related to whom we vote for than in-party love. In much the same way, who we…

What Arizona’s 2010 ban on ethnic studies could mean for the fight over critical race theory

What Arizona’s 2010 ban on ethnic studies could mean for the fight over critical race theory

Hank Stephenson writes: Despite a few pockets of wealth, Tucson Unified School District is a largely poor district that serves a majority-Latino population. White students make up only about 20 percent of the district, and the vast majority of students qualify for free and reduced-priced lunches. TUSD’s students fall behind their peers around the state in standardized testing, and students of color fall even further behind their white peers. [Augustine] Romero and other Mexican American studies founders hoped that by…

Tennessee abandons vaccine outreach to children

Tennessee abandons vaccine outreach to children

The Tennessean reports: The Tennessee Department of Health will halt all adolescent vaccine outreach – not just for coronavirus, but all diseases – amid pressure from Republican state lawmakers, according to an internal report and agency emails obtained by the Tennessean. If the health department must issue any information about vaccines, staff are instructed to strip the agency logo off the documents. The health department will also stop all COVID-19 vaccine events on school property, despite holding at least one…

America only punishes rebels who threaten the status quo

America only punishes rebels who threaten the status quo

Jamelle Bouie writes: The United States has never struggled to punish those radicals who stood against hierarchy and domination. Whether you were a labor radical, Black revolutionary or left-wing militant, to attempt to upset existing class and social relations — or, at times, to even associate with people who held those ideas — was to court state repression. The two Red Scares of the 20th century are evidence enough of this fact. When a perceived internal enemy is a threat…

China’s extreme weather warnings avoid talk of climate change

China’s extreme weather warnings avoid talk of climate change

Bloomberg reports: As unprecedented heatwaves sweep across large parts of the Northern Hemisphere, China is telling its people to brace for another summer of dangerous floods and droughts. China’s National Climate Center this month predicted “generally poor weather conditions” for the rest of the summer and warned that the country will face more extreme weather events than usual. In some areas, precipitation is estimated to be 20% to 50% higher than normal. Some major rivers, including the Yellow River that…

The left needs free speech

Katha Pollitt writes: When W.W. Norton decided to cease distributing Blake Bailey’s biography of Philip Roth after several women accused Bailey of rape and other outrages, I called up my local bookstore and reserved a copy. When Amazon stopped selling When Harry Became Sally, which argues from a conservative point of view that it is not possible to change your sex, I went to Alibris.com and bought a used one. I would have bought the Dr. Seuss books withdrawn from…

Will Covid-19 change science? Past pandemics offer clues

Will Covid-19 change science? Past pandemics offer clues

Science reports: Although the past may not presage the future, epidemic history illuminates how change unfolds. “Historians often say that what an epidemic will do is expose underlying fault lines,” says Erica Charters, a historian of medicine at the University of Oxford who is studying how epidemics end. But how we respond is up to us. “When we ask, ‘How does the epidemic change society?’ it suggests there’s something in the disease that will guide us. But the disease doesn’t…

Our climate change turning point is right here, right now

Our climate change turning point is right here, right now

Rebecca Solnit writes: Human beings crave clarity, immediacy, landmark events. We seek turning points, because our minds are good at recognizing the specific – this time, this place, this sudden event, this tangible change. This is why we were never very good, most of us, at comprehending climate change in the first place. The climate was an overarching, underlying condition of our lives and planet, and the change was incremental and intricate and hard to recognize if you weren’t keeping…

The ocean is full of tiny plastic particles – we found a way to track them with satellites

The ocean is full of tiny plastic particles – we found a way to track them with satellites

Plastic fragments washed onto Schiavonea beach in Calabria, Italy, in a 2019 storm. Alfonso Di Vincenzo/KONTROLAB /LightRocket via Getty Images By Christopher Ruf, University of Michigan Plastic is the most common type of debris floating in the world’s oceans. Waves and sunlight break much of it down into smaller particles called microplastics – fragments less than 5 millimeters across, roughly the size of a sesame seed. To understand how microplastic pollution is affecting the ocean, scientists need to know how…

EPA approved toxic chemicals for fracking a decade ago, new files show

EPA approved toxic chemicals for fracking a decade ago, new files show

The New York Times reports: For much of the past decade, oil companies engaged in drilling and fracking have been allowed to pump into the ground chemicals that, over time, can break down into toxic substances known as PFAS — a class of long-lasting compounds known to pose a threat to people and wildlife — according to internal documents from the Environmental Protection Agency. The E.P.A. in 2011 approved the use of these chemicals, used to ease the flow of…

‘Surprising amount of death’ will soon occur in U.S. regions with low vaccination rates, expert says

CNN reports: As the Delta variant rapidly spreads, US hot spots have seen climbing case numbers — and an expert warns a “surprising amount of death” from Covid-19 could soon follow. The US is averaging about 19,455 new cases over the last seven days, a 47% increase from the week prior, according to data from Johns Hopkins University. And a third of those, CNN Medical Analyst Dr. Jonathan Reiner said, come from five hot spots: Florida, Louisiana, Arkansas, Missouri and…

‘Everyone has a tipping point’: Hunger fuels Cuba’s protests

‘Everyone has a tipping point’: Hunger fuels Cuba’s protests

The New York Times reports: Hospitals and pharmacies have run out of medicines as basic as penicillin and aspirin. Blackouts have become maddeningly frequent and agonizingly long. Cubans lucky enough to have foreign currency wait in line for hours for staples like beans and rice. A searing economic decline, leading to hardships Cubans have rarely seen since the collapse of the Soviet Union devastated their country in the 1990s, has stirred the island’s largest protest movement in decades, eliciting a…

Lawyers retreat from pro-Trump election suit

Lawyers retreat from pro-Trump election suit

Politico reports: The legal reckoning for attorneys who pushed former President Donald Trump’s spurious claims of election fraud advanced on Monday, with a federal court in Detroit holding a hearing on whether to impose sanctions over a suit filed last year seeking to decertify Joe Biden’s victory in Michigan and declare Trump the winner. Two of the most prominent attorneys in the pro-Trump camp — Dallas-based Sidney Powell and Atlanta-based L. Lin Wood — are among the lawyers who brought…
