Bright green stalks of weeds are sprouting from the ground where planes were supposed to take off at a new Mexico City airport as officials let nature take over in their bid to transform the marshy swath of an ancient lake into a giant park. The ghostly skeletons of a partly built control tower and flight terminal are recognizably in the style of Norman Foster, the British architect commissioned by Mexico’s last president to build a futuristic international airport at a cost of $13 billion on 4,800 hectares just east of the capital. Upon taking office in December 2018, President Andres Manuel Lopez Obrador axed the project, citing the results of an informal referendum, after arguing it would be costly to prevent sinking on the waterlogged soil. Instead of the slick design from Foster, whose award-winning glass and steel weblike buildings dot the globe, Lopez Obrador opted to expand an existing military airport. Workers prepare native plants at the garden center near the canceled airport zone as part of a project to conserve 12,200 hectares of land in Texcoco on the outskirts of Mexico City, Mexico, Sept. 3, 2020.The abandoned construction zone is now part of a project to conserve 12,200 hectares of marsh on what was once massive Lake Texcoco before Spanish colonizers in the 1600s began draining the water to prevent flooding in their burgeoning settlement. About half that area is slated for public use, including sports and events space more than twice the size of New York’s Central Park. Architect Iñaki Echeverria, who is overseeing the project, aims to open a portion of the park by March next year and offer full access by 2024. “The restoration began the moment the construction stopped. This shows nature’s incredible resiliency,” he said. Officials point to recent flooding as proof that maintenance would have been difficult and say less than 20% of construction was completed. They paid about $603 million to cancel more than 600 contracts left in limbo. During a recent visit, a moat of green water had risen around a flying-saucer-like building where a control tower juts 20 meters high, less than a third of its intended height. Unfinished parts of the flight terminal at an abandoned construction site of a Mexico City airport are now flooded by summer rains, in Texcoco on the outskirts of Mexico City, Mexico, Sept. 4, 2020.Birds glided in a pond beneath columns of crisscrossing steel bars that were meant to become a terminal greeting 70 million passengers a year. The steel will be sold as scrap. Conservation efforts in the area date to the 1970s, when the government grappled with how to contain dust storms that swept from the dry lake basin over Mexico City. The current project has been hailed by Lopez Obrador as a “new Tenochtitlan,” referring to the centuries-old Aztec capital built in the middle of a sprawling lake, where Mexico City is today. Part of Echeverria’s work is convincing city dwellers that the wetlands are worth visiting. “People who think there’s nothing there, don’t know it well,” he said.

Bulked-up, mutant “mighty mice” held onto their muscle during a monthlong stay at the International Space Station, returning to Earth with ripped bodybuilder physiques, scientists reported Monday.  The findings hold promise for preventing muscle and bone loss in astronauts on prolonged space trips like Mars missions, as well as people on Earth who are confined to bed or need wheelchairs. A research team led by Dr. Se-Jin Lee of the Jackson Laboratory in Connecticut sent 40 young female black mice to the space station in December, launching aboard a SpaceX rocket.  In a paper published in the Proceedings of the National Academy of Sciences, Lee said the 24 regular untreated mice lost considerable muscle and bone mass in weightlessness as expected — up to 18%. But the eight genetically engineered “mighty mice” launched with double the muscle maintained their bulk. Their muscles appeared to be comparable to similar “mighty mice” that stayed behind at NASA’s Kennedy Space Center.  FILE – In this photo released by NASA on Oct. 17, 2019, U.S. astronauts Jessica Meir, left, and Christina Koch pose for a photo in the International Space Station. The two, along with Andrew Morgan, looked after the space mice.In addition, eight normal mice that received “mighty mouse” treatment in space returned to Earth with dramatically bigger muscles. The treatment involves blocking a pair of proteins that typically limit muscle mass. A SpaceX capsule brought all 40 mice back in good condition, parachuting into the Pacific off the California coast in January. Some of the ordinary mice were injected with the “mighty mice” drug after returning and quickly built up more muscle than their untreated companions, Lee said. The scientists completed the experiment just as the coronavirus was hitting the U.S. “The only silver lining of COVID is that we had time to write it up very intensively” and submit the results for publication, said Dr. Emily Germain-Lee of Connecticut Children’s Medical Center, Lee’s wife who also took part in the study. Both are affiliated with the University of Connecticut.  While encouraged by their findings, the couple said much more work needs to be done before testing the drug on people to build up muscle and bone, without serious side effects. “We’re years away. But that’s how everything is when you go from mouse to human studies,” Germain-Lee said. Lee said the experiment pointed out other molecules and signaling pathways worth investigating — “an embarrassment of riches … so many things we’d like to pursue.” His next step: possibly sending more “mighty mice” to the space station for an even longer stay. Three NASA astronauts looked after the space mice, performing body scans and injections: Christina Koch and Jessica Meir, who performed the first all-female spacewalk last fall, and Andrew Morgan. They are listed as co-authors.

Suellen de Souza could no longer endure the confinement. After six months of precautions, the Brazilian nursing technician decided that Sunday would be her first day at the beach since the pandemic began.
“This week it was very hot … the truth is I really wanted to come” to the beach, said the 21-year-old at Rio de Janeiro’s Ipanema beach, which is technically still closed to sun-bathers though few respect the prohibition and authorities seldom enforce it.
Under a burning midday sun, she had difficulty finding an empty space in the sand as thousands crowded the famed beach, which was dotted with hundreds of umbrellas and families sunning themselves. Beach-goers were packed close together with few wearing face masks.
With tentative signs the coronavirus pandemic is easing, Brazilians exhausted with quarantine measures and social distancing are increasingly relaxing precautions and flooding beaches as if the pandemic were over. They are being urged to do so – and violate the recommendations of health experts – by President Jair Bolsonaro, who has resisted many lockdown measures and pressed for a return to normal life from the beginning, famously calling the novel coronavirus a “little flu.”
“It is like a rain that is going to reach you,” Bolsonaro said of the virus on July 7, the day he confirmed his own infection from which he has since recovered.
In Rio, recommendations by health experts to remain isolated are being challenged even by people like Souza, a nursing technician who worked in a field hospital for coronavirus patients.
“The coronavirus is being controlled a little more, that gave me security to go out,” she said.
The same scenario is playing out in Sao Paulo, Brazil’s worst-hit state with more than 855,000 confirmed infections and 31,000 deaths. Thousands of residents took advantage of the long weekend to travel to the coast.
“If you stay indoors for a long time, you will go crazy. I was like that. The moment I found out the beach was open, I decided to come,” said Josy Santos, a 26-year-old teacher who spent the day in Guarujá, a seaside resort an hour from Sao Paulo.
With more than 4,100,000 confirmed infections and 126,000 deaths from the virus, Brazil has the second highest totals in both figures behind only the United States. In recent weeks, Latin America’s largest country has left a new case number plateau that had dragged on from almost three months and started seeing a reduction in the number of new confirmed cases. But with an average of 820 deaths per day, its numbers are still considered high by health experts.
Patricia Canto, a pulmonologist at Brazil’s premier biomedical research and development lab, the Oswaldo Cruz Foundation, or Fiocruz, warned that if Brazilians are negligent the country could see a repeat of what happened in Europe, especially Spain, where second waves of new cases were seen.
“Spain controlled the pandemic, but there were new outbreaks when many young people were negligent during the summer,” Canto said. If Brazil’s “population is not conscientious and continues to frequent beaches and bars without precautions, it might mirror this.”
Geraldo Tadeu, political scientist and coordinator of the Center for Studies and Research on Democracy, said the lack of coordination among levels of government in the COVID-19 fight demoralized many Brazilians.
“After six months, no one can stand to stay indoors seeing how there are no clear guidelines for fighting the virus,” said Tadeu. “As there is no serious policy, the population is exhausted. People head out to the streets when they see that others are not complying and the effort of staying home is no longer worth it.”
More than 6 months after the start of the pandemic, Brazilians seem increasingly relaxed about taking precautions to fight the virus’ spread. Some attribute this to Bolsonario’s denial rhetoric.
Souza said many do not believe in taking precautions because “Bolsonaro did not believe in the disease … He did not set an example.”
But Sao Paulo Gov. Joao Doria, who clashed with Bolsonaro over quarantine measures, does not think this is necessarily the case. The congestion and vehicle flow on Sao Paulo’s highways this weekend exceeded that seen during Carnival in February.
“We see the same problem (of full beaches) in Spain, the United States and England, which do not see these speeches against social distancing,” Doria told The Associated Press.
