An ash and gas plume rises from Hunga volcano, Tonga, on 14 January 2022. Global geophysical observations reveal that the climactic eruption that followed on 15 January produced a broad range of atmospheric waves, with pressure wave amplitudes comparable with those from the 1883 Krakatau eruption. While propagating over the world’s oceans, the remarkable atmospheric waves generated complex fast-traveling tsunamis. See pages 30, 91, and 95.
My forearms are sticking to the desk as I type this month’s letter.It’s an irksome feeling that’s offset by last night’s joy of dancing wildly at a wedding and an afternoon dip in a kind friend’s swimming pool. Summer in Florence is an intoxicating mix of sweat, fun and gelato. While many of us escape to our countries of origin for as long as we can, there’s something undeniably alluring about these sun-streaked months in Tuscany. Just think back to movies such as Stealing Beauty and Under the Tuscan Sun before fast forwarding to recent Netflix films Toscana and Love & Gelato. Stereotypes aside—and there are far too many to mention in these productions (Netflix, we’re here if you fancy delving deeper into our city and region!)—summer in Florence never stops working its inexplicable magic. Yes, the wall of heat and buzz of mosquitoes may be draining during the day, but the night brings boundless pleasures, from movie nights by the Uffizi to exhibitions at just-reopened Forte di Belvedere, refreshing beers beside the Arno and brilliantly oddball cultural moments such as a wheat threshing festival in the hills (find out more about that gem on page 16).
Tanners at the Chouara Tannery have been transforming animal hides into leather since the 11th century. The tanning process has gone unchanged since then, but it relies on heavy chemicals that threaten the health of workers. Some say they are not willing to take that risk. We traveled to the world’s oldest leather tannery in Fez, Morocco, to find out how this ancient craft is still standing.
Ukraine won the short war. Now comes the long war, and so far, Russia is winning. But it does not have to be fought on Vladimir Putin’s terms
Ukraine won the short war. Mobile and resourceful, its troops inflicted terrible losses and confounded Russian plans to take Kyiv. Now comes the long war. It will drain weapons, lives and money until one side loses the will to fight on. So far, this is a war that Russia is winning.
In recent days its forces have taken the eastern city of Severodonetsk. They are advancing on Lysychansk and may soon control all of Luhansk province. They also threaten Slovyansk, in the north of next-door Donetsk. Ukrainian leaders say they are outgunned and lack ammunition. Their government reckons as many as 200 of its troops are dying each day.
The cover shows an artistic representation of various cancer cells. The large-scale gains, losses and rearrangements of DNA seen in chromosomal instability are a typical feature of cancer — but there is no comprehensive framework to decode the causes of this genomic variability and their possible links to disease. In this week’s issue, Florian Markowetz, Geoff Macintyre and their colleagues present such a framework with a compendium of 17 signatures of chromosomal instability that can be used to predict how tumours might respond to drugs and that help to identify future therapeutic targets. The team created the compendium by examining 7,880 tumours representing 33 types of cancer. In a separate paper, Nischalan Pillay and colleagues examined 9,873 cancers to generate
Glide through the waterways of Botswana’s Okavango Delta and come face to face with its wildlife in this immersive 360 experience. Through Okavango Eternal, work is underway to help protect the source waters of this one-of-a-kind region, and support tourism that benefits local communities.
The Okavango Delta is a vast inland river delta in northern Botswana. It’s known for its sprawling grassy plains, which flood seasonally, becoming a lush animal habitat. The Moremi Game Reserve occupies the east and central areas of the region. Here, dugout canoes are used to navigate past hippos, elephants and crocodiles. On dry land, wildlife includes lions, leopards, giraffes and rhinos.
Venice, the capital of northern Italy’s Veneto region, is built on more than 100 small islands in a lagoon in the Adriatic Sea. It has no roads, just canals – including the Grand Canal thoroughfare – lined with Renaissance and Gothic palaces. The central square, Piazza San Marco, contains St. Mark’s Basilica, which is tiled with Byzantine mosaics, and the Campanile bell tower offering views of the city’s red roofs.
The visit to commemorate 25 years since Britain returned the city to Beijing, marked a milestone in the Chinese leader’s pledge to deliver a strong and unified nation as he moves to extend his rule.16 min ago8 min read
