El caso de Ryan Wedding, el exatleta olímpico que según Estados Unidos se convirtió en un presunto líder criminal que trabajaba con el cartel de Sinaloa, ha generado un choque de versiones entre autoridades estadounidenses y mexicanas, al igual que con la defensa legal del exdeportista.

Wedding quedó bajo custodia de autoridades el jueves 22 de enero, pero hasta ahora no está claro en qué circunstancias ocurrió esto.

El director del Buró Federal de Investigaciones de Estados Unidos (FBI, por sus siglas en inglés), Kash Patel, dijo al día siguiente que Wedding fue arrestado en México en “una operación de alto riesgo”.

“Nuestros equipos del FBI ejecutaron con precisión, disciplina y total profesionalismo junto con nuestras contrapartes mexicanas para traer a Ryan James Wedding de vuelta para enfrentar a la justicia. Uno de los criminales más peligrosos del mundo ya no está más en las calles”, dijo Patel el viernes en X.

Esta declaración, sin embargo, contrasta con la que dio el secretario de Seguridad y Protección Ciudadana de México, Omar García Harfuch, quien esa semana —junto con otras autoridades mexicanas— se reunió con Patel en la Ciudad de México. El mismo viernes, García Harfuch dijo en X que Wedding “se entregó voluntariamente” el jueves en la Embajada de Estados Unidos.

Horas más tarde, el embajador de Estados Unidos en México, Ron Johnson, también se refirió al hecho como una “entrega voluntaria” y no un arresto, a diferencia de lo dicho por el director del FBI.

“La entrega voluntaria de Ryan Wedding fue resultado directo de la presión ejercida por las autoridades de procuración de justicia de México y de los Estados Unidos, que trabajaron en estrecha coordinación y cooperación”, dijo Johnson en un comunicado, en el que destacó las acciones del Gobierno de Donald Trump contra el narcotráfico.

La defensa de Wedding, por su parte, tiene otra versión sobre lo sucedido.

El abogado de Wedding, Anthony Colombo, dijo esta semana que su cliente no se entregó sino que fue detenido.

“Fue arrestado, no se rindió”, dijo en Estados Unidos, y aseguró que agentes estadounidenses sí habrían participado en la operación en la que fue arrestado en México.

El lunes, en su primera audiencia judicial en Estados Unidos, Wedding se declaró no culpable de cargos de narcotráfico ante una Corte de California.

El cruce de versiones ha levantado cuestionamientos hacia el Gobierno de México, donde la presidenta Claudia Sheinbaum insiste en que su país no permite operaciones extranjeras en su territorio porque estas vulnerarían la soberanía nacional.

La mandataria recibió preguntas sobre el tema durante su conferencia de prensa de este jueves, que se realizó horas después de que sostuvo una llamada con Trump. Durante su encuentro con periodistas, Sheinbaum dijo que no entrará en controversia con el director del FBI e insistió en que Wedding se entregó.

“No voy a entrar en mayor discusión con el director de FBI, pero que quede claro que nosotros no vamos a aceptar operaciones, se lo decimos siempre al presidente Donald Trump y ellos han visto que hemos ido avanzando”, dijo.

“Nosotros nunca vamos a aceptar operaciones conjuntas o de fuerzas federales o de Estados Unidos estatales en nuestro territorio. Si colaboramos nos dan información y también nosotros le damos información, pero también las operaciones de nuestro territorio son de fuerzas mexicanas eso tiene que quedar muy claro”, insistió.

Las declaraciones se suman a otras que Sheinbaum ha realizado desde que Trump inició su segundo mandato el 20 de enero de 2025. Frente a las declaraciones del presidente de Estados Unidos, quien ha dicho que ha ofrecido su ayuda a México para enfrenta

(CNN) — President Donald Trump did another social media posting spree on Wednesday night and Thursday morning. As with Trump’s previous posting blitzes, this one was filled with wildly inaccurate and often conspiratorial claims about elections and other subjects.

Here’s a debunking of two of them.

No, Walmart isn’t shutting down 250 California stores

Trump twice shared a video titled “California Governor PANICS as Walmart Shuts Down 250+ Stores Across State.” The video, echoed by the text in one of the posts Trump shared, claimed that Walmart is preparing to shut down these stores because the retailer can’t afford California’s “$22” per hour minimum wage.

But California’s statewide minimum wage is $16.90 per hour, not $22 – and Walmart told CNN on Thursday morning that it isn’t conducting a massive store closure in California for any reason.

“This isn’t accurate information,” a Walmart spokesperson said. “In fact, we actually just recently opened a new store in California.”

California Gov. Gavin Newsom’s office posted on social media on Wednesday night expressing disbelief that Trump had promoted both the false claim about Walmart – “Walmart’s 303 stores in California are open,” Newsom’s office wrote – and an even wilder but equally fake anti-Newsom conspiracy theory the president also shared during the social media blitz.

Newsom’s office wrote: “We cannot believe we have to say any of this out loud. We cannot believe this is real life. And we truly cannot believe this man has the nuclear codes.”

The phony claim about Walmart shutting hundreds of California stores was previously posted on a YouTube account that appears to have been devoted to sensational but inaccurate videos attacking Newsom.

On Thursday, Newsom’s office provided CNN with a screenshot from the YouTube account, which an aide said was taken Wednesday night, that showed the account had posted numerous highly similar recent videos making sensational false claims about life in California under Newsom.

By Thursday morning, almost all of the anti-Newsom videos had been deleted from the account.

No, Wisconsin doesn’t have millions more registered voters than actual adults

Multiple posts from Trump on Wednesday night and Thursday morning made false claims about elections, including conspiracy theories about the 2020 election the president wrongly insists was stolen from him. One particularly preposterous post Trump shared outlined a (nonexistent) vote-flipping conspiracy involving former President Barack Obama, the FBI, the CIA, China and Italian officials.

Other posts made claims that were more straightforward, but no less false. For example, Trump twice shared posts claiming that Wisconsin has more than seven million registered voters, millions higher than its total number of adults; one of the posts said, “This is not a glitch; it is election fraud waiting to happen!”

But Wisconsin does not have anywhere close to seven million

(CNN) — If you’re someone who thrives after dark, you might want to pay extra attention to your heart health.

Night owls — those who naturally stay up late — may be more likely to develop heart disease, a new study has found. But experts say there are steps you can take to protect your health.

Middle-aged and older adults, especially women, who are more active in the evenings may have worse heart health than those without a strong morning or evening preference, according to a study published Wednesday in the Journal of the American Heart Association.

This study analyzed data from more than 322,000 adults who participated in the UK Biobank, a longitudinal study that included participants from England, Scotland and Wales.

Participants self-identified their chronotype — their natural preference for sleep-wake timing — and were categorized as morning, intermediate or evening types. (The study did not assign specific wake or bedtimes to these categories; classification was based solely on self-reported preference.)

Chronotypes reflect “a person’s natural preference for sleep timing and daily rhythms,” whether they are early birds, night owls or in between, said Dr. Sina Kianersi, the study’s lead author and a postdoctoral research fellow at Brigham and Women’s Hospital and Harvard Medical School in Boston.

Adults with an evening chronotype and potentially even those who wake up early could be at high risk due to their internal body clocks not matching up with work schedules and other external factors.

Many earlier studies focused on a single risk factor such as smoking or blood pressure, but the new research used the American Heart Association’s Life’s Essential 8, which outlines ways to improve and maintain heart health. Those eight factors are eating healthy, being active, not smoking, getting high sleep quality, and managing weight, cholesterol, blood sugar and blood pressure. Each component is scored from 0 to 100, with higher scores indicating better cardiovascular health. These are averaged to create a composite score for each person.

Kianersi said the strong association between being a night owl and having poor overall cardiovascular health was most surprising. Night owls were much more likely to have unhealthy habits or risk factors such as poor diet, less exercise or smoking. The connection was even stronger for women.

Compared with the intermediate category, “evening types/night owls were about 79% more likely to have an overall poor cardiovascular health, and they also had a higher risk of heart attack or stroke during follow-up,” he said.

Daily routine matters, too.

“Being an evening chronotype is often associated with other factors that can increase cardiovascular disease risk, such as more irregularity in the timing of sleep, meals, and light exposure,” said Sabra Abbott, an associate professor of neurology at Northwestern University’s Feinberg School of Medicine. She was not involved in the study.

Night owls had a 16% higher risk of developing cardiovascular disease, such as heart attack or stroke, compared with intermediate chronotypes, over a period of almost 14 years of follow-up.

People who identified as early birds were 5% less likely to have poor heart health and habits compared with those in the intermediate group.

Because his research focused on middle-aged and older adults, Kianersi said that more studies are needed to determine if the same patterns apply to younger people. He also noted that, as an observational study, the findings cannot prove that chronotype directly causes poorer cardiovascular health or increased cardiovascular risk.<

(CNN) — Scientists have long believed that longevity is shaped by lifestyle choices; however, a new study reveals that genes may play a larger role in determining how long people live.

Genetics accounts for over half of differences in lifespan — two times higher than earlier estimates. Still, the finding may resonate with what people see on their family trees or what they hear during their annual physical.

“It’s not surprising at all,” said Dr. Deborah Kado, a co-director of the Stanford Longevity Center, who was not involved in the study. While scientists agree that most traits have a nature and nurture component, lifespan was thought to be driven largely by environment.

The finding, published Thursday in the journal Science, suggests that longevity is akin to other complex traits — such as cholesterol levels and osteoporosis risk — that are thought to be shaped by many genes but also heavily influenced by how and where people live.

Previous studies underestimated the influence of genetics because they relied on data from people born before the 19th century. These individuals typically died of infectious diseases and accidents before vaccines, medications, modern-day hygiene practices and safety regulations became widely available.

When these factors were included in older studies, they overshadowed genetic factors influencing age. Uri Alon, the lead author of the study, explains that by cleaning up the data to exclude these factors, “genes shine out to their full effect.”

“People were thinking, ‘Oh, genes are probably irrelevant,’” said Alon, who studies lifespan at the Weizmann Institute of Science in Israel. “But we have a genetic lifespan kind of predetermined in our genes.” Genes, though, don’t tell the whole story.

People still have some control over their lifespan

Although 55% of a lifespan is set, the remaining 45% is up in the air. “Some of it is luck, and some of it is our decision,” Alon explained.

According to Alon, those lifestyle choices — like exercise, diet and social connection — can shift a person’s genetically influenced age by about five years. “Genetics is not a done deal.”

Someone genetically predetermined to live 80 years could reach 85 with healthy habits, while unhealthy lifestyle choices can shorten that expectancy to 75.

“But healthy habits won’t get you from 80 to 100 if your genetics are 80,” he said.

Life expectancy in the United States reached a record high of 79 years in 2024, according to data released this week by the US Centers for Disease Control and Prevention. It trended up for decades before dropping by nearly a year and a half around the Covid-19 pandemic.

That’s why Kado says products marketed to improve longevity are not the answer to a longer life. Instead, it comes down to exercise, diet and social connection.

The genes that determine genetic potential

Though some genes have been identified as protective or harmful when it comes to aging, Kado says traits like longevity are far more complicated than a few genetic factors.

“There isn’t any one gene,” Kado said. “Biology is complicated” – so complex that she says many of the elements that come together
