School closures and culture wars turned classrooms into battlegrounds — and made the head of one of the country’s largest teachers’ unions a lightning rod for criticism.
The U.S. Congress began imposing debt limits in 1776. When the Continental Congress authorized its very first loan from France, it instructed U.S. commissioners to borrow a “sum not exceeding two million sterling.” Congress continued to permit the Treasury to borrow only up to bond-by-bond specific limits until 1917. Prior to then, U.S. Treasury secretaries actually operated under multiple debt limits, authorized bond by authorized bond. The single, aggregate debt limit we’re more familiar with today was first adopted by the U.S. in 1939.

Science Magazine – April 28, 2023 issue: Mammals come in a wide variety of shapes and sizes, here represented by some of the least well known and most unusual—clockwise from top left: a fossa, a Hoffmann’s two-toed sloth, a lesser hedgehog tenrec, two tree (or white-bellied) pangolins, and an aye-aye.
Mammals are one of the most diverse classes of animals, ranging both in size, across many orders of magnitude, and in shape—nearly to the limit of one’s imagination. Understanding when, how, and under what selective pressures this variation has developed has been of interest since the dawn of science.
The 240 mammals sequenced through the Zoonomia project include the famous sled dog Balto, who was reported to have led a team of sled dogs in the final leg of the race to carry a life-saving serum to Nome, Alaska, in 1925. His genome, in conjunction with others, was used to reveal his ancestry and adaptations, as well as predict aspects of his morphology, including his coat color.

The destructive behavior of great earthquakes in subduction zones, such as in Japan in 2011, depends on details of the earthquake slip. A slip at shallow depth is the dominant driver of tsunami. Using recently developed seafloor geodetic instrumentation, Brooks et al. found that the deeper slip of the July 2021 magnitude 8.2 Chignik, Alaska earthquake was followed 2.5 months later by a second stage of (aseismic) slip. This approximately 2 to 3 meters of “silent” slip allowed the shallow fault to catch up with its deeper portion, reducing its future earthquake potential.
The country needs a new political settlement that diminishes the power of extremists
As israel marks its 75th anniversary, take a moment to admire how it has triumphed against the odds. Before it declared independence in 1948 its own generals warned that it had only a fifty-fifty chance of survival. Today Israel is hugely rich, safer than it has been for most of its history, and democratic—if, that is, you are prepared to exclude the territories it occupies. It has overcome wars, droughts and poverty with few natural endowments other than human grit. It is an outlier in the Middle East, a hub of innovation and a winner from globalisation.
Or Russian fighter jets may win control of Ukrainian skies
As Ukraine prepares its forces for a crucial counter-offensive, the argument among its Western allies about what equipment to provide chunters on. Having finally received the tanks it had been pleading for since last year, Ukraine has increased the intensity of its demands for fighter jets. Yet its pleas are falling on largely deaf ears.

It’s an evening in 1531, in the city of Venice. In a printer’s workshop, an apprentice labors over the layout of a page that’s destined for an astronomy textbook—a dense line of type and a woodblock illustration of a cherubic head observing shapes moving through the cosmos, representing a lunar eclipse.
Monocle Magazine (May 2023 issue) – As the canny, optimistic winners of this year’s Monocle Design Awards all demonstrate, staying on top of your game in any field requires the instincts of a true detective – and a curiosity to find out what makes the world tick, writes our editor in chief, Andrew Tuck.

“I was a motorcycle hater,” says Stefan Ytterborn. That is, before the Swedish entrepreneur tried a few electric ones and got so hooked that he decided to design his own. Cake’s first model, Kalk, put competitors to shame with a design weighing 40 per cent less than the average motorbike. In 2021 Cake started shipping out Kalk &, an upgrade engineered for both commutes and off-road escapades. “During the week you ride the bike from home to work, and during the weekend you bring it out to the countryside,”…
Facility will produce up to five billion bacteria-infected mosquitoes per year

The non-profit World Mosquito Program (WMP) has announced that it will release modified mosquitoes in many of Brazil’s urban areas over the next 10 years, with the aim of protecting up to 70 million people from diseases such as dengue. Researchers have tested the release of this type of mosquito — which carries a Wolbachia bacterium that stops the insect from transmitting viruses — in select cities in countries such as Australia, Brazil, Colombia, Indonesia and Vietnam. But this will be the first time that the technology is dispersed nationwide.
Americas Quarterly (Spring 2023) – Love him or not, the return of Luiz Inácio Lula da Silva is a watershed moment not just for Brazil, but Latin America as a whole. The 77-year-old is “the region’s only diplomatic heavy hitter and the most globally visible Latin American leader of his generation,” writes Oliver Stuenkel in this issue’s cover story.

A diplomatic heavy hitter is back at the helm of Latin America’s largest country—but the path to an influential international role is full of obstacles.
AQ tracks priorities in external relations, including positions on Venezuela and China, in eight countries.
Amid growing tensions between the world’s largest superpowers, much of Latin America has taken an independent approach to foreign relations. Countries are increasingly following a path that Chilean scholars Carlos Fortin, Jorge Heine and Carlos Ominami titled the “active non-alignment option.” Regional integration is a top concern for some leaders, while others are seeking engagement far beyond the Western Hemisphere. Meanwhile, policy choices have to contend with domestic infrastructure challenges and a global concern with the impacts of climate change.
London Review of Books (LRB) – May 4, 2023 issue: French President Emmanuel Macron and the Pension Crisis, India Prime Minister Narendra Modi’s ‘Big Con’ and more.
Pensions – and ‘the fiscal impact of ageing’ – have long troubled the EU. A European Commission paper published in 2016 noted with relief that ‘most EU member states’ were reforming their pension systems. France is one of them. During his first term in office Emmanuel Macron envisaged an ambitious reform plan, but Covid-19 put paid to it. Re-elected in 2022, he put a different plan on the table; at its core is an increase in the retirement age from 62 to 64. It has been predictably unpopular. Pensions rank high on the list of French state expenditures. They are one of the cornerstones in France’s edifice of public provision, which is why the sound of drilling and hammering sets most citizens’ teeth on edge.
