When the Khoisan hunter-gatherers of sub-Saharan Africa gazed upon the meandering trail of stars and dust that split the night sky, they saw the embers of a campfire. Polynesian sailors perceived a cloud-eating shark. The ancient Greeks saw a stream of milk, gala, which would eventually give rise to the modern term “galaxy.”
In the 20th century, astronomers discovered that our silver river is just one piece of a vast island of stars, and they penned their own galactic origin story. In the simplest telling, it held that our Milky Way galaxy came together nearly 14 billion years ago when enormous clouds of gas and dust coalesced under the force of gravity. Over time, two structures emerged: first, a vast spherical “halo,” and later, a dense, bright disk. Billions of years after that, our own solar system spun into being inside this disk, so that when we look out at night, we see spilt milk — an edge-on view of the disk splashed across the sky.
Yet over the past two years, researchers have rewritten nearly every major chapter of the galaxy’s history. What happened? They got better data.

Archaeologists in Pompeii, the city buried in a volcanic eruption in 79 AD, have made the extraordinary find of a frescoed hot food and drinks shop that served up the ancient equivalent of street food to Roman passersby.

This annus horribilis is not over yet, and it has now taken away from us the greatest doyen and scholar of Urdu literature the world knew over the recent decades, Shamsur Rahman Faruqi. He died peacefully at his home, surrounded by his family and his favourite dogs, having recovered earlier this month from Covid-19. I had the honour and pleasure to visit him in his study in January this year, which isn’t anything less than a library. It is hard to imagine all those books siting there without their avid reader. Ghalib’s often quoted verse “aisā kahan se laun ki tujh saa kahen jise” – “where do I find another who may be like you?” – doesn’t seem to hold truer than in this moment of the greatest loss for Urdu culture.

When Philippa Perry finished, after several years of writing and a lifetime of research, the first draft of her book about improving relationships between parents and children, she sent it to her editor – and their relationship promptly collapsed.
The question has confounded many: How does Pakistan stay alive?
The human cost of coronavirus has continued to mount, with more than 77m cases confirmed globally and more than 1.69m people known to have died.
Although the modern standard is officially exact, it isn’t actually exact. Two atomic clocks of the same design keep slightly different times. By statistically comparing atomic clocks, we know they are accurate to about one second in thirty million years. That’s probably accurate enough for everyday use, but it isn’t accurate enough for some scientific purposes. If we had more precise clocks, we could use them to study everything from geology to dark energy. So there is an ongoing quest to develop a new, more accurate standard.
Some plants are so entwined with tradition that it’s impossible to think of one without the other. Mistletoe is such a plant. But set aside the kissing custom and you’ll find a hundred and one reasons to appreciate the berry-bearing parasite for its very own sake. David Watson certainly does. So enamored is the mistletoe researcher that his home in Australia brims with mistletoe-themed items including wood carvings, ceramics and antique French tiles that decorate the bathroom and his pizza oven. And plant evolution expert Daniel Nickrent does, too: He has spent much of his life studying parasitic plants and, at his Illinois residence, has inoculated several maples in his yard — and his neighbor’s — with mistletoes. But the plants that entrance these and other mistletoe aficionados go far beyond the few species that are pressed into service around the holidays: usually the European Viscum album and a couple of Phoradendron species in North America, with their familiar oval green leaves and small white berries. Worldwide, there are more than a thousand mistletoe species. They grow on every continent except Antarctica — in deserts and tropical rain forests, on coastal heathlands and oceanic islands. And researchers are still learning about how they evolved and the tricks they use to set up shop in plants from ferns and grasses to pine and eucalyptus.
As a young child, I did not put much thought into who had led the Chinese against Japan. Once, at home, I had heard my father make a casual comment that the War of Resistance, as World War II is known in China, was mostly fought by the Nationalists. When I repeated the statement over dinner, my mother stared at her husband as if he were one of her disobedient students. After a long, awkward silence, she turned to look at me and said, “the Nationalists and the Communists cooperated,” before telling everyone at the table to never speak of this again.
It’s more than good news.
