No tienes que dejar la dosis matutina de cafeína para proteger tu cerebro contra la demencia en el futuro. Nuevas investigaciones muestran que el consumo diario de café o té —y sí, del tipo con cafeína— está asociado con una mejor salud cognitiva a largo plazo.

Aquellos que disfrutaron de dos a tres tazas de café o una a dos tazas de té al día vieron el mayor impacto, según el estudio publicado este lunes por la Revista de la Asociación Médica Estadounidense JAMA, por sus siglas en inglés.

Los bebedores de café en la mediana edad tenían aproximadamente un 18 % menos de probabilidades de desarrollar demencia más adelante, mientras que los bebedores de té tenían un 14 % menos de riesgo, dijo el autor principal del estudio, el Dr. Daniel Wang, profesor asistente en el departamento de nutrición de la Escuela de Salud Pública Harvard T.H. Chan de la Escuela de Medicina de Boston.

Wang y su equipo no observaron el mismo beneficio en las opciones descafeinadas en los datos de más de 130.000 personas inscritas en el Nurses’ Health Study y el Health Professionals Follow-up Study.

Otras investigaciones han apoyado la idea de que el café con cafeína puede estar vinculado a un envejecimiento más saludable y que el café y el té con cafeína pueden reducir el riesgo de condiciones como enfermedades cardíacas.

Lo más importante que hay que destacar es que la evidencia no demuestra que debas abandonar tu dosis matutina para mantenerte saludable, dijo el Dr. David Kao, titular de la cátedra Jacqueline Marie Schauble Leaffer en Enfermedad Cardíaca en Mujeres y profesor asociado de medicina en la Escuela de Medicina Anschutz de la Universidad de Colorado. No participó en el último estudio.

La investigación se fortalece en parte gracias a su dependencia en el Nurses’ Health Study y el Health Professionals Follow-up Study, que son dos bases de datos a largo plazo que evaluaron repetidamente la dieta. Sin embargo, fue un estudio observacional, lo que significa que los investigadores pueden ver la asociación pero no pueden asegurar que la ingesta de cafeína haya causado el envejecimiento más saludable.

El vínculo entre ambas podría deberse a otros factores, dijeron los expertos. Por ejemplo, podría haber un elemento además de la cafeína que sea saludable, pero descafeinar el café o el té también elimina ese nutriente. O los bebedores de café podrían tener mejores dietas, mayor estatus socioeconómico o hábitos saludables comunes, como hacer un crucigrama matutino al tomar su café, dijo Kao.

Aunque pueda parecer lógico asumir que es buena idea añadir o aumentar tu consumo de cafeína según estudios recientes como este, Kao dijo que la evidencia no es lo suficientemente fuerte como para sugerir que las personas deban cambiar sus comportamientos.

“Más no es necesariamente mejor”, dijo la Dra. Sara Mahdavi, profesora adjunta en el departamento de ciencias de la nutrición de la Universidad de Toronto, en un correo electrónico. Ella no participó en la investigación. “Nadie debería empezar a beber café únicamente para proteger el cerebro”.

Las personas con ansiedad, insomnio, condiciones de ritmo cardíaco o que hayan tenido malas reacciones a la cafeína deben ser especialmente cautelosas, agregó.

La cafeína podría no ser el único beneficio al beber café y té.

El café, por ejemplo, “contiene cafeína junto con cientos de compuestos bioactivos que influyen en la inflamación, el metabolismo de la glucosa, la función vascular y el estrés oxidativo”, dijo Mahdavi.

El café puede reducir la inflamación, la presión arterial y el estrés oxidativo (

(CNN) — An immigration judge terminated removal proceedings against Tufts University doctoral student Rümeysa Öztürk, who was detained for over a month last year as part of the Trump administration’s effort to target and deport international students and activists involved in pro-Palestinian advocacy, her lawyers said Monday.

The Department of Homeland Security hadn’t met its burden to prove Öztürk’s removability, prompting the immigration court to end removal proceedings against her, according to a letter from her attorneys submitted in court and a federal appeals court docket.

The move comes after recently unsealed court documents showed the federal government didn’t have any evidence that Öztürk had been supporting terrorist activity when she was arrested, and that her visa revocation and arrest were because of an opinion article she wrote containing criticisms of Israel.

“Today, I breathe a sigh of relief knowing that despite the justice system’s flaws, my case may give hope to those who have also been wronged by the U.S. government,” Öztürk wrote in a statement Monday. “Though the pain that I and thousands of other women wrongfully imprisoned by ICE have faced cannot be undone, it is heartening to know that some justice can prevail after all.”

Her immigration attorney said the judge’s decision was “a powerful affirmation of fairness and the rule of law.”

“We are grateful that the Judge carefully considered the facts and the law, and we hope this decision serves as a reminder that immigration enforcement must always be guided by justice,” Mahsa Khanbabai said in a statement to CNN.

Öztürk was detained outside her home in March 2025 as the administration sought to deport her after revoking her student visa.

Chilling video of the PhD student’s arrest showed a swarm of officers encircling her near her home in Somerville, Massachusetts, as she shrieked in fear, sparking national outrage.

That same month, Secretary of State Marco Rubio posted on X that the Trump administration “will be revoking the visas and/or green cards of Hamas supporters in America so they can be deported.”

Homeland Security spokeswoman Tricia McLaughlin told CNN at the time that DHS and Immigrations and Customs Enforcement investigations had found that Öztürk had “engaged in activities in support of Hamas, a foreign terrorist organization that relishes the killing of Americans.”

A DHS spokesperson called the immigration judge’s ruling “judicial activism” to “keep a terrorist sympathizer in this country.”

“We are under no obligation to admit them or let them stay here. Sec. Noem has made it clear that anyone who thinks they can come to America and hide behind the First Amendment to advocate for anti-American and anti-Semitic violence and terrorism – think again,” the spokesperson said.

Öztürk’s arrest came a year after she co-authored a campus newspaper op-ed that was critical of Tufts University’s response to the war in Gaza, and her attorneys have said that she was targeted by the administration in an attempt to chill pro-Palestinian speech in violation of her constitutional rights.

The PhD student, originally from Turkey and on a valid F-1 student visa, was shuttled through multiple states following her arrest and suffered a series of asthma attacks without adequate medical care, according to her attorneys.

A State Department memo said Öztürk’s visa was revoked following an assessment that her actions “‘may undermine U.S. foreign policy by creating a hostile environment for Jewish students and indicating support for

Toluwa estaba esperando su vuelo en una sala del aeropuerto en Washington cuando, según dijo, fue abordada por un desconocido.

Ambos empezaron a conversar y, después de un rato, ella accedió a intercambiar números con él. No fue hasta que llegó a casa y buscó sus redes sociales que descubrió que él había publicado varios videos de sí mismo intentando ligar con mujeres en aeropuertos.

Estos videos fueron grabados usando una cámara incorporada en sus gafas inteligentes, que parecen gafas normales y corrientes y que, aunque todavía son relativamente poco comunes, están ganando popularidad.

“Me puse a investigar, encontré su TikTok. Descubrí que hace estos videos de ‘rizz’,” dijo Toluwa, usando un término de jerga popular derivado de “carisma” para referirse a videos en redes sociales que muestran a hombres acercándose a mujeres en público e intentando conquistarlas. Toluwa pidió ser identificada solo por su primer nombre por razones de privacidad.

Mientras seguían en contacto por mensajes, Toluwa contó que el hombre le envió el video que había grabado de ella sin su conocimiento, diciendo que quería “consultarla” antes de compartirlo en línea.

Ella dijo que él intentó convencerla de que le diera su consentimiento para hacerlo; sin embargo, a pesar de que ella no estuvo de acuerdo explícitamente, él lo subió a las redes sociales. “Se viralizó y llegó al punto en que la gente empezó a mandarme este video, alguien se me acercó en Union Market, que es un espacio grande en Washington, y me lo puso en la cara y me preguntó, ¿eres tú?”.

Las redes sociales están llenas de videos de hombres grabándose a sí mismos acercándose a mujeres en espacios públicos e intentando coquetear con ellas o pidiéndoles su número. En muchos casos, los videos se graban y suben a plataformas como TikTok e Instagram sin el permiso o conocimiento de la persona grabada.

Estos videos, a menudo grabados desde el punto de vista del hombre que se acerca a una persona, acumulan miles y, en algunos casos, millones de visualizaciones. Una vez publicados, pueden atraer comentarios misóginos.

Aunque el concepto del “pick-up artist” no es nuevo, los expertos están dando la voz de alarma sobre el auge de los llamados “manfluencers” que graban a mujeres de manera encubierta para crear contenido misógino en Internet.

El término “manfluencer” describe a un amplio grupo de figuras en redes sociales que crean contenido dirigido a hombres. Mientras que algunos publican contenido inofensivo como rutinas de gimnasio y consejos de autoayuda, otras cuentas son más siniestras.

En este ámbito digital, las mujeres suelen ser presentadas “como una conquista, un premio o una recompensa”, dijo a CNN Stephanie Wescott, académica feminista, escritora y conferencista, y profesora de Educación, Cultura y Sociedad en la Universidad Monash de Australia.

Las gafas inteligentes pueden ser una herramienta ideal para estos creadores de contenido porque envían un mensaje claro sobre el poder, advirtió. Es decir, que los hombres pueden “estar observando, grabando y, por lo tanto, controlando la imagen de las mujeres en espacios públicos sin que ellas lo sepan y, en consecuencia, mostrando que los espacios públicos pertenecen a los hombres”.

Para Wescott, este fenómeno representa otro ejemplo del abuso de la tecnología con perspectiva de género, y un peligro para las mujeres que es difícil de anticipar. “El peligro es la pérdida de autonomía corporal sin siquiera ser consciente de lo que está ocurriendo”

(CNN) — As the Justice Department faced mounting pressure to release the Epstein files last year, FBI employees were compiling what one described as “salacious” allegations against men in Jeffrey Epstein’s orbit and putting together a presentation that included a list of “prominent names” in the investigative files.

The 21-slide presentation — released with more than 3 million documents in the Epstein files — outlines the various federal investigations into the late convicted sex offender, his death and his longtime associate Ghislaine Maxwell, who was convicted of child sex trafficking.

One slide lists a dozen names and notes that “numerous” tips were made anonymously to the FBI’s tip line. Some of the tips included claims of sexual misconduct, while others were not allegations of criminal conduct but rather indicated an association with Epstein.

The men listed, including President Donald Trump, former President Bill Clinton and Andrew Mountbatten-Windsor, have been known to have associations with Epstein and have denied wrongdoing regarding previous allegations against them.

Efforts by FBI employees to compile some of the most explosive claims contained in the Epstein files took place as public backlash mounted last year over the Trump administration’s decision to shut the door on releasing more documents. Separately, the FBI compiled a list of sexual assault allegations related to Trump this past August — many of which appear to have come from unverified tips.

Eventually, Congress passed a law in November demanding transparency and the release of all documents, forcing the Trump administration to act.

It’s not clear from the presentation what steps had been taken to verify any of the allegations. Deputy Attorney General Todd Blanche told CNN earlier this month that the Department of Justice has no plans to bring additional charges related to Epstein, saying there was nothing in the files to warrant new prosecutions.

CNN has reached out to the DOJ. The FBI declined to comment.

Top Trump administration officials early last year hyped the release of the Epstein files and a purported “client list,” which has been long sought since Epstein’s death in 2019, including by Trump’s base.

Attorney General Pam Bondi initially said last February that a client list was sitting on her desk — though the administration said she was referring to other documents. Later that month, she gave a group of rightwing influencers binders labeled “The Epstein Files: Phase 1,” which turned out to contain already publicized documents related to the sex offender.

Under pressure because of the lack of new details, Bondi promised more documents would be released.

But the administration began backtracking, CNN previously reported, sometime around May 2025 — the same month that Bondi told Trump in a meeting that his name was included in the files.

This sparked backlash that intensified after the DOJ said on July 7 in an unsigned memo that it had concluded there was no client list and that Epstein had died in 2019 by suicide — undercutting conspiracy theories to the contrary. The department did not plan to release any new documents on the matter, an official told CNN at the time.
