Concern about the Popocatepetl volcano changes with the wind. While east of the mountain residents swept streets and didn’t remove their masks on Tuesday, here to the west, they casually watched the gas and ash plume emerging from its crater.

The 17,797-foot (5,425-meter) mountain just 45 miles (about 70 kilometers) southeast of Mexico City and known affectionately as “El Popo,” has been belching for days, dusting towns and crops in Puebla in a super-fine ash.

“When nothing is happening we worry,” said a cheerful Viridiana Alba, who has been selling flowers in Amecameca’s central plaza for 25 years. “El Popo,” as the volcano is affectionately known, rises directly across from her stand.

“We know that right now it’s releasing smoke, that’s freeing the energy that it holds,” she said. Ash still rests on the awning that shades her plants from when the wind blew her way last weekend. The town was shaken by the volcano’s tremors, but as long as the ash remains light she believes it will help her plants.

Winds have blown a large plume of ash east over Puebla and Veracruz states and eventually the Bay of Campeche and beyond.

Mexico’s National Center for Prevention of Disasters said in its report Tuesday that small domes of lava continued forming inside the crater that were then being destroyed by small and moderate explosions. It advised that people living in communities near the volcano would likely continue those explosions over the coming days and weeks.

Three days ago “my house shook almost all night, it was amazing,” said Arturo Benítez, a former local official. “The sound of the volcano was strong, it resembled a lit boiler and a lot of ash fell, but then suddenly on this side it settled down.”

That was Sunday, when authorities raised the alert level, while maintaining there is not current risk to the population.

No evacuations have been ordered, but authorities have been driving evacuation routes, preparing some shelters and doing simulation drills.

On Cortes Pass, a small highway that crosses a saddle between Popocatepetl and the inactive Iztaccihuatl volcano, a couple dozen civil defense vehicles and soldiers blocked the way Tuesday.

The road was closed to traffic and most of the cabins that draw tourists were empty.

Cástula Sánchez, 75, who sells food to tourists on the weekends, was confident Popocatepetl would settle down again and the tourists would return. She lives in nearby San Pedro Nexapa where three decades ago lava arrived close to her home before they could evacuate, but they were spared.

Now she runs a local information service from the back of her shop. Residents bring her short messages scribbled on a piece of paper that she then reads over a loudspeaker the whole community can hear. So far authorities have asked nothing of her, just to keep an eye out.

In Amecameca, police handed out pamphlets with tips on being prepared in case the volcano’s activity increased. The pamphlet recommended having important documents at hand, a full gas tank, masks and towels to dampen if residents had to leave in a hurry.

Most residents already know, especially those who remember an eruption in 1997 that “darkened the sky, thundered ... and a muddy rain fell,” Benítez said.

“The pyroclastic cloud came to Amecameca and it was chaos, everyone wanted to leave then and it was tremendous,” he said.

The only time Popocatepetl triggered a red alert on the government’s stoplight-style system since emerging from decades of dormancy in 1994 was in 2000. The volcano’s last major eruption was more than 1,000 years ago.

The activity this time has so far not been significant for locals, but the localized impacts could be real for residents on one side of the volcano while everything is normal on the other.

Benítez who worked years ago as a photographer with federal authorities monitoring the volcano said he thought coverage in recent days had been a bit exaggerated. “It’s not that bad, except if they know something we don’t know, because the activity has lessened.”

President Andrés Manuel López Obrador too downplayed the situation Tuesday.

“We are going to be watching and if there's anything we're going to inform,” he said. “But we feel like there isn't going to be a problem.”



Scientists Unravel the History of Cotton Domestication

Cotton, the world's most profitable nonfood crop, is used more than any other natural fiber. Known for its comfort and durability, it has been utilized since antiquity in fabrics and other goods. Four species are grown commercially, but one is dominant, accounting for about 90% of global production.

Scientists have now unraveled the domestication history of this important species - called Gossypium hirsutum, or upland cotton - with some genomic sleuthing.

They determined that it was first domesticated in Mexico in the northwestern part of the Yucatan peninsula. The region at the time was populated by Stone Age farmers, long before the Maya civilization flourished there.

Iowa State University botanist and evolutionary biologist Jonathan Wendel said this domestication occurred at least 4,000 years ago, and perhaps up to 7,000 years ago.

The researchers pinpointed where domestication occurred by comparing the genomes of the domesticated species to wild cotton species found in the Yucatan, Florida and the Caribbean islands of Puerto Rico and Guadeloupe.

The domesticated species most closely matched wild Yucatan cotton, Reuters reported.

"Wild cotton plants are woody, multibranched shrubs or small trees, long-lived, with relatively sparse flowering ⁠and smaller flowers, fruits ⁠and seeds than under cultivation," said Wendel, co-senior author of the study published on Monday in the journal Proceedings of the National Academy of Sciences.

"Members of some human groups must have taken an interest in the wild forms," Wendel said, setting in motion the process of domestication from which the modern crop form arose over thousands of years of slow and gradual improvement.

"Early farmers saw potential in this sprawling plant with hairy seeds as a source for soft materials. Early weavers could spin fiber by hand and use it for weaving cloth, fish nets, ropes and other goods," Iowa State University geneticist and evolutionary biologist and study co-senior author Corrinne Grover said.

Upland cotton ⁠was introduced to the rest of the world following the Spanish conquests in the Americas in the 16th century. China, India, the United States and Brazil are now the world's leading cotton producers.

"Research is showing that the process of domestication, of transforming these short, coarse and brownish fibers into the fine, white and superior textile we know today likely involves many genes operating in a complex symphony," Grover said.

"The fibers themselves are just single-celled seed hairs, but are among the most exaggerated and remarkable cells in plants," Wendel said.

The study found that the domesticated cotton plant possesses far less genetic diversity - the variety of genetic characteristics within a species - than its wild counterparts. Less genetic diversity can lower the ability of a species to adapt to environmental changes such as exposure to diseases.

"We know that domestication often leads to a loss of genetic diversity as early farmers were selecting for valuable traits, and then to further reductions as crop improvement intensified the selection pressure," Grover said.

"Here, we can see what this means globally ⁠for the cotton genome, and how ⁠it compares to what still remains in the wild. This wild diversity is important because traits that were inadvertently lost - certain pest resistance, for example - may be valuable in incorporating into our modern cultivars," Grover said.

Another cotton species - Gossypium barbadense, or extra-long staple cotton - was domesticated in the Americas, in Peru or Ecuador, at roughly the same time as upland cotton, and now constitutes approximately 5% of world cotton production. Two other domesticated species - Gossypium arboreum from the Indian subcontinent and Gossypium herbaceum from sub-Saharan Africa and the Arabian Peninsula - make up the rest.

Cotton far exceeds other fiber crops such as flax, jute and hemp in production.

"The demand for cotton, while varying year to year, remains high and appears to be on a general upward trend," Grover said.

The invention of the cotton gin, a machine that automated the separation of seeds from cotton fibers, in the United States at the end of the 18th century dramatically increased processing speeds and made cotton farming highly profitable. This drove an expansion of slavery in the US South amid increased demand for labor to plant, pick and harvest the valuable crop.

"Cotton has a complicated history, most notably its association with slavery, exploitation of Indigenous peoples and imperial expansion. But it is also an enduring crop, one that is woven into the lives of people worldwide," Grover said.

African Ants at the Center of International Smuggling … Queen Sold for Over $1,000

Kenyan ant expert Dino Martins gushes over the red and black insects that have become the center of an international smuggling trade.

Martins has been visiting the network of nests of these Giant African Harvester Ants outside Nairobi for 40 years.

“They're big and bold... They're the tigers of the ant world,” the entomologist told AFP.

“Each nest here has just one queen and she is the mother who founded this nest 40, 50 or even 60 years ago,” he said.

Martins was shocked when he learned that thousands of queens from this Messor cephalotes species were being harvested and shipped abroad in syringes and test tubes to be sold for hundreds of dollars each.

The trade came to light in Kenya last year when two Belgian teenagers were arrested in possession of nearly 5,000 queen ants, and accused of “biopiracy.”

Kenyan authorities fear a new form of poaching, focused less on ivory and furs, and more on insects, reptiles and rare plants.

The judge even compared it to the slave trade.

“Imagine being violently removed from your home and packed into a container with many others like you... It almost sounds as if the reference above is to the slave trade,” he said in his ruling.

The Belgians were handed a fine of around $8,000, but as more cases have emerged, sentences have hardened: last month a Chinese national was sentenced to one year in prison for attempting to traffic 2,000 ants.

On several European websites, the queens go for around 200 euros ($230).

Colonies can take 20-30 years to produce new queens. They provide all manner of services to the ecosystem: dispersing grass seeds, aerating the soil, and providing food for animals like pangolins.

Martins also considers the smuggling trade unethical simply because “ants have feelings.”

The trade “exploded” with the arrival of the internet, said Jerome Gippet, a researcher at the Swiss University of Fribourg.

Formerly the interest of a few passionate individuals, it eventually gave way to sophisticated networks of collectors, intermediaries and smugglers.

A study Gippet published in 2017 found more than 500 ant species -- a third of the total -- were sold online. More than 10% were potentially invasive with uncertain impacts on foreign ecosystems.

“I'm not advocating for a ban on the ant trade. It's very useful in educational terms, in terms of reconnecting with nature, or simply providing enjoyment... But it has to be done responsibly,” he said.

A Jackson Pollock painting sold for a record $181.2 million on Monday at Christie's in New York, leading a blockbuster day at the auction house.

With its black drips of paint accented by touches of red on a huge canvas spanning over three meters (nine feet), Pollock's "Number 7A, 1948" sold for $181.2 million, including fees.

According to ARTnews, the sale makes it the fourth most expensive work ever sold at auction.

The previous auction record for the abstract expressionist painter was $61.2 million, set in 2021. Other works by him have been sold privately for up to $200 million.

"It is with this work that Pollock finally frees himself from the shackles of conventional easel painting and produces one of the first truly abstract paintings in the history of art," Christie's said in a statement.

"Danaide," a bronze head sculpted around 1913 by Romanian-born artist Constantin Brancusi, sold for $107.6 million, topping its previous record of $71.2 million set in 2018.

"No. 15 (Two Greens and Red Stripe)" by American painter Mark Rothko sold for $98.4 million, while Catalan artist Joan Miro's "Portrait of Madame K." was bought for $53.5 million.

The sales smashed previous records for Rothko ($86.9 million) and Miro ($37 million) set in 2012.

Monday's eye-watering auction follows a string of records set at Sotheby's in November last year.

Austrian master Gustav Klimt's "Portrait of Elisabeth Lederer", which he painted between 1914 and 1916, sold for $236.4 million, becoming the second most expensive work ever sold at auction.

"The Dream (The Bed)" (1940), a self-portrait by Mexican artist Frida Kahlo, sold for $54.7 million, setting a record for the price of a painting by a woman.

The most expensive painting ever sold at auction remains the "Salvator Mundi," (Savior of the World), a Renaissance work attributed to Leonardo da Vinci, which was bought for $450 million in 2017.
