Los resultados que apenas comienzan a surgir ofrecen cierta tranquilidad, dicen los expertos.Dos grupos, uno en China y otro en Suecia, han informado públicamente sus resultados y se esperan más este lunes desde Estados Unidos. Hasta ahora, los primeros resultados pintan a BA.2.86 más como un tigre de papel que como la bestia amenazante que parecía ser al principio, aunque esa impresión podría cambiar a medida que lleguen más resultados.BA.2.86, también conocida con el sobrenombre de Pirola, captó la atención del mundo porque parece radicalmente diferente a cualquier otra variante del coronavirus que hayamos visto hasta ahora.Parece que todo el mundo tiene covid-19.

Takeaways from AP’s reporting on efforts to restore endangered red wolves to the wild

Published Tue, 04 Mar 2025 05:14:57 GMT

ALLIGATOR RIVER NATIONAL WILDLIFE REFUGE, N.C. (AP) — The red wolf’s journey from extinction in the wild to conservation poster child and back to the brink has been swift and stunning.The only wolf species unique to the United States, Canis rufus once roamed from Texas to Long Island, New York. Today, the last wild populations, totaling about two dozen animals, are clinging to existence on two federal wildlife refuges in eastern North Carolina.The U.S. Fish and Wildlife Service is preparing an updated recovery plan to ensure the species’ survival in the wild. But the plan counts on private landowners to tolerate the wolves, and history is not on the side of “America’s wolf.”Here are the key takeaways from the AP’s reporting:WHY WERE RED WOLVES DECLARED EXTINCT IN THE WILD?After generations of killings, habitat loss and pressure from human development, the red wolf was declared “threatened with extinction” under the Endangered Species Preservation Act of 1966. With the signing of the...

Sudan’s top general heads to South Sudan for talks with its president on the war

Published Tue, 04 Mar 2025 05:14:57 GMT

CAIRO (AP) — Sudan’s top military general is headed to South Sudan to talk with its president on his second trip abroad since the war in his country started earlier this year.Gen. Abdel-Fattah Burhan, chairman of the ruling Sovereign Council, will discuss the conflict in Sudan with South Sudanese President Salva Kiir, according to a statement from the council.In April, simmering tensions between the military, led by Burhan, and the powerful paramilitary Rapid Support Forces, commanded by Mohammed Hamdan Dagalo, exploded into open fighting in the capital and elsewhere.The conflict has turned Khartoum into an urban battlefield, with the RSF controlling vast swaths of the city. The military command, where Burhan has purportedly been stationed since April, has been one of the epicenters of the conflict.In his trip to Juba, Burhan is accompanied by acting Foreign Minister Ali al-Sadiq and Gen. Ahmed Ibrahim Mufadel, head of the General Intelligence Authority, and other military officers,...

Iga Swiatek’s US Open title defense and stay at No. 1 end with a loss to Jelena Ostapenko

Published Tue, 04 Mar 2025 05:14:57 GMT

NEW YORK (AP) — Iga Swiatek arrived at the U.S. Open as its reigning champion, as the winner at three of the past six Grand Slam tournaments and as the owner of the No. 1 ranking for nearly 1 1/2 years. None of that mattered on Sunday night against Jelena Ostapenko, whose powerful style disrupts Swiatek’s rhythm — and beats her every time.Swiatek’s title defense at Flushing Meadows ended in the fourth round with a 3-6, 6-3, 6-1 loss to 2017 French Open champion Ostapenko in the fourth round at Arthur Ashe Stadium. The result also means Swiatek’s stay at atop the WTA will end next week, when current No. 2 Aryna Sabalenka will rise to the top spot for the first time.“There are some sad emotions” about falling from No. 1, Swiatek acknowledged, while also saying of her reign atop women’s tennis: “It was pretty exhausting.”Not long after being assured of losing her grip on that perch, the 22-year-old from Poland already was thinking ahead to returning ...

Endangered red wolves need space to stay wild. But there’s another predator in the way – humans

Published Tue, 04 Mar 2025 05:14:57 GMT

ALLIGATOR RIVER NATIONAL WILDLIFE REFUGE, N.C. (AP) — Jeff Akin had to bite his tongue.He was chatting with a neighbor about efforts to protect and grow the area’s red wolf population. The endangered wolves are equipped with bright orange radio collars to help locals distinguish the federally protected species from invasive, prolific coyotes.“If I see one of those wolves with a collar on, I’m going to shoot it in the gut, so it runs off and dies,” Akin says the neighbor told him. “Because if it dies near you, and they come out and find the collar, they can arrest you.”Akin is a hunter and the walls of his country house are lined with photos of the animals he’s killed. But what he heard made him sick.“I wouldn’t shoot a squirrel in the stomach if I was hungry,” he says. “It’s just not humane.”In a way, the anecdote sums up the plight of this uniquely American species.Once declared extinct in the wild, Canis rufus — the only wolf species found solely in the United States — was r...

Drone strikes on Russia

Published Tue, 04 Mar 2025 05:14:57 GMT

On 30 August, Russia was subjected to the largest drone attack since their invasion of Ukraine. As a result, 2 Il-76 aircraft were destroyed by drones in Pskov, while 2 other aircraft were seriously damaged. Such attacks have become commonplace: the Moscow business centre Moscow City alone was hit by 3 drone attacks during the summer - more and more Russians feel that war has come to their territory. This is the logical payback for the geopolitical adventure of the greatest war criminal of our time – Vladimir Putin.Ukraine's military-industrial complex has announced a plan to produce at least 200,000 drones per year - some of them are capable of travelling at least 800 km, remaining invisible to Russian air defences. Ukraine has a wide range of UAVs: strike, reconnaissance and surface-to-air. They are increasingly used against military facilities in the Russian Federation, as well as against factories whose products are used in the Russian military-industrial complex. An example is ...
