(CNN) — Some things in life feel unavoidable: death, taxes and … brushing your teeth.

Yet for all the “practice” you get caring for your pearly whites — ideally, you’re brushing twice a day and flossing daily, year in and year out — you’d think you’d be a pro at it by now.

But the health data tell a different story. Tooth decay, which includes cavities or caries, is the most common noncommunicable disease around the globe, a statistic that holds true even in the United States. That, despite the fact that cavities are largely considered to be avoidable.

“If something that’s almost entirely preventable is the most prevalent disease on the planet among adults and kids, maybe we should reconsider what we’ve been telling people,” dentist and orthodontic specialist Dr. Kami Hoss told CNN Chief Medical Correspondent Dr. Sanjay Gupta recently on his podcast, Chasing Life.

Millions of people who stay on top of daily oral care and twice-yearly dental checkups can still manage to get cavities, noted Hoss, an educator, entrepreneur and author of “If Your Mouth Could Talk: An In-Depth Guide to Oral Health and Its Impact on Your Entire Life.”

Hoss calls the mouth “one of the most important organs” of the body, with a whole world of oral microbes, saliva, soft tissues and bones.

“A lot of people think your mouth is just teeth,” he said, noting it’s intimately connected to the lower jaw and the maxilla, which includes the upper jaw, nasal cavity floor and eye socket orbit. Not to mention, “your tongue posture impacts the way you breathe, your speech and your taste,” he said.

Add to all that, your mouth and teeth also affect the way you look. Oral health “impacts all of these areas,” he said, including “systemic health, mental health, personal successes, professional successes, our dating life, how much money we make.”

Hoss is also passionate about oral health because it affects so many other bodily systems.

“It goes way deeper. For some reason — probably the disconnection between medicine and dentistry — people forget that the mouth is not a separate entity. It is the opening to your body,” Hoss said.

He explained the microbes in a person’s mouth can — especially if there are conditions like bleeding gums, active tooth decay or an imbalanced oral microbiome — release things like toxins, inflammatory cells and free radicals into the bloodstream.

“They can not only damage the blood vessels,” he said. “They can travel to the heart and cause infections or inflammation, they can go to the brain, they can go to joints, they can go to an unborn baby and cause complications.”

But, back to the mouth and the seemingly intractable issue of tooth decay.

“The problem is, if I ask the next 100 people I’m going to see today, ‘How do you get cavities?’ they’re all going to tell me, ‘If you don’t brush your teeth enou

Las acciones en Estados Unidos bajaron este jueves, prolongando un reciente periodo de volatilidad, mientras Wall Street lidia con la persistente inquietud en torno a la inteligencia artificial y datos económicos mostraron que el mercado laboral se debilitó en los últimos dos meses.

El Dow cayó 637 puntos, o 1,29 %. El S&P 500 retrocedió 1,37 % y el Nasdaq Composite, de fuerte peso tecnológico, bajó 1,74 %.

El indicador del miedo de Wall Street, el VIX, se disparó 22 % y superó los 20 puntos, un umbral que señala una volatilidad elevada en los mercados.

El Nasdaq se encaminaba a su peor racha de tres días desde abril, mientras los inversionistas lidian con el potencial de la IA para trastocar la industria del software. Un fondo cotizado en bolsa que sigue al sector del software caía 3 % el jueves y acumula ocho sesiones consecutivas a la baja.

“El detonante de corto plazo fue el lanzamiento del complemento de Anthropic, pero los inversionistas vienen lidiando con el sector del software desde hace varios meses, a medida que la IA reduce la necesidad de programadores y afecta las fuentes de ingresos de varias compañías”, escribió en una nota Mohit Kumar, estratega de Jefferies.

“Actualmente el mercado está en una etapa de disparar primero y preguntar después”, señaló Kumar. “También están surgiendo preocupaciones en torno a las firmas de capital privado y de crédito privado, dada su exposición al sector”.

Mientras el impacto de la IA en el software está en el centro de atención, Wall Street atraviesa la temporada de resultados corporativos y persisten las dudas sobre cuán rentables serán las apuestas de las grandes tecnológicas por el auge de la IA.

Las acciones de Microsoft (MSFT) caían 3,2 % y han retrocedido en cinco de las últimas seis sesiones, luego de que el gigante tecnológico reportara resultados hace una semana.

Las acciones de Alphabet (GOOG) se desplomaron 4,5 % y se encaminaban a su peor jornada desde mayo, después de que la compañía presentara resultados y delineara planes para aumentar el gasto en centros de datos y proyectos vinculados a la IA. El Nasdaq acumula una caída de más de 6% desde su último récord, marcado en octubre.

Las criptomonedas también se vieron afectadas por el ánimo de aversión al riesgo. El bitcoin cayó por debajo de los US$ 67.000 y tocó su nivel más bajo en 15 meses.

El oro, que suele considerarse un refugio en momentos de incertidumbre, cayó 2,3 %. La plata se desplomó 13 %, prolongando un reciente episodio de volatilidad extraordinaria.

Las acciones ampliaron sus pérdidas la mañana del jueves después de que dos informes económicos separados dibujaran un panorama de fragilidad en el mercado laboral. Los bonos del Tesoro de EE.UU. subieron, lo que hizo bajar los rendimientos.

La encuesta mensual de Ofertas de Empleo y Rotación Laboral (JOLTS, por sus siglas en inglés) mostró que las vacantes laborales en diciembre cayeron a su nivel más bajo desde 2020, según la Oficina de Estadísticas Laborales.

Esos datos económicos más débiles de lo esperado se conocieron tras cifras de Challenger, Gray & Christmas que mostraron que el mes pasado fue el peor enero para anuncios de recortes de empleo desde 2009.

El índice Fear and Greed de CNN se mantenía en zona de “miedo”.

(CNN) — If you’ve spent any time online, you’ve probably heard the phrase “you don’t know ball” used to point out a lack of knowledge.

It seems that some of those complaining most loudly about Bad Bunny being picked to headline the Super Bowl LX halftime show don’t know ball.

At least, they don’t seem to know that the National Football League (NFL) is not new to global superstars, nor controversy. The Puerto Rican “DeBi TiRAR MaS FOToS” singer’s selection has come with both – but will also bring more eyes from around the world onto the sport in a way the league has been craving.

The NFL’s quest to bolster its international fan base has been the driving force behind having more games played abroad, according to Sam Sanders, host of KCRW’s “The Sam Sanders Show.”

The league has been “seeing what’s happening with FIFA and with the World Cup and the way that soccer is truly an international sport and saying, ‘We want that too,’” he told CNN.

For the 2026 football season, the NFL has announced regular season games to be played in London, Madrid, Melbourne, Mexico City, Munich, Paris and Rio de Janeiro.

The six international games aired in 2025 on the NFL Network — which included games in Dublin, London, Berlin and Madrid — averaged 6.2 million viewers across television and digital, according to Nielsen figures shared by the league. That’s the highest season viewership average for international games on record, they added.

But they want more, and the easiest way to do that? “Have the biggest pop star in the world, who happens to sing in Spanish and is big globally, play your halftime show,” Sanders said.

To Jorell A. Meléndez-Badillo, a historian and author of “Puerto Rico: A National History” whose historical writings about the territory were incorporated into Bad Bunny’s YouTube content, it makes sense.

“I think it was a marketing decision on behalf of the NFL – to have a Spanish-speaking artist that just so happens to be the biggest star in the world,” he told CNN.

In search of a cultural touchdown

Some conservatives have taken issue with Bad Bunny, born Benito Antonio Martínez Ocasio, for years, whether it was his flirtation with gender fluid fashion or his outspoken criticism of Donald Trump’s administration and its immigration policies.

Online, conservatives have threatened to boycott the Super Bowl and the NFL more broadly, with influential voices like Newsmax host Greg Kelly and Tomi Lahren openly criticizing the league for choosing Bad Bunny as the performer.

President Trump recently said he would not be attending the game and criticized the involvement of both Bad Bunny and rock band Green Day, who are longtime critics of his and are scheduled to perform as part of a special tribute before the game.

“I’m anti-them,” Trump said. “I think it’s a terrible choice. All it does is sow hatred. Terrible.”

It appears someone forgot to tell NFL commissioner Roger Goodell to be worried.

During the commissioner’s annual state of the league address on Monday, Goodell defended Bad Bunny’s selection, saying he is “one of the great artists in the world” and “that’s one of the reasons we chose him.”

“But the other reason is he understood the platform he was on, and that this platform is used to unite people, and to be able to bring people together with their creativity, with their talents, and to be able to use t

(CNN) — Anthropic’s Cowork AI assistant sent shockwaves through Wall Street this week. Now Anthropic is taking another leap forward, improving its model.

Anthropic’s new Claude Opus 4.6 model, announced Thursday, is designed to make Cowork AI better for office and coding work, potentially raising even more concerns that the AI tool could replace specialized software packages that companies use for those tasks.

Legal and financial analysis software stocks have plunged in recent days, bringing the broader stock market down with them. The Nasdaq just had its worst two-day tumble since April, and it’s down another 0.7% Thursday.

Many experts wonder whether AI will ultimately cost some workers their jobs. Tech giants like Anthropic, OpenAI and Google are locked in a race to build AI models that they hope will underpin the future workplace.

Anthropic rival OpenAI just introduced a new platform for creating AI agents meant to function like colleagues Thursday morning. And Anthropic launched its Cowork tool in January.

It remains uncertain whether AI investments will pay off for businesses adopting the technology. Anthropic is betting that its new model will help it replicate the massive success of its Claude Code software but for other types of office work.

“We think that Opus 4.6 is going to be an inflection point for knowledge work in many ways,” Dianne Penn, head of product management for research, said in an interview with CNN ahead of the announcement.

What’s new

One of those ways involves how Opus 4.6 processes data. Anthropic says it’s expanded Opus’ context window, which is the amount of information a model can remember at once, from 200,000 tokens to one million. Tokens are a unit of measurement referring to how AI models understand text. The longer and more complex a query is, the more tokens it requires.

Giving Claude the ability to process more information at once should enable it to handle more complicated tasks, like making sweeping changes to entire code bases, said Penn.

With Opus 4.6, Claude will also be better at knowing when it should take more time to think through a request – a technique known as reasoning – and when it should answer quickly.

Anthropic also says the new model outperforms OpenAI’s GPT-5.2 model on a benchmark evaluating how AI handles knowledge work in fields like finance and legal.

The new PowerPoint integration, available in research preview, will let users build slides using Claude, with the AI able to read layouts and fonts to create slides that align with the desired corporate template. This was particularly challenging because unlike Excel, which is primarily data-driven, PowerPoint slides involve making judgements about design elements like colors and text placement, said Penn.

Anthropic says files that Claude Opus 4.6 works on, like documents, spreadsheets and slides, will be closer to “production-ready” on the first try, meaning they should require less human intervention.

While Anthropic’s Opus 4.6 makes Claude better at non-technical work, the update also includes some improvements for software engineers. Coding duties can be split across teams of agents instead of having one agent work through individual tasks, mimicking the way a human engineering team would operate, Anthropic says.

AI shakes the software industry

The release comes after software stocks cratered this week following the release of plugins for Anthropic’s Cowork tool last Friday. These plugins, which let users tailor Anthropic’s Cowork tool for specific industries like legal, finance

Al dar la bienvenida a los líderes extranjeros en el Desayuno Nacional de Oración, el presidente Donald Trump destacó al presidente de El Salvador, Nayib Bukele, como un “gran aliado”, y lo llamó “una de mis personas favoritas”.

Trump agregó: “Ha sido increíble. Ha sido un gran aliado de este país”.

Durante su discurso, Trump se refirió a las cárceles de El Salvador, y afirmó que Bukele “administra cárceles bastante grandes… y hacen un trabajo muy humano, pero son cárceles muy duras”.

El Gobierno de Trump ha enviado a cientos de migrantes deportados a El Salvador, incluyendo decenas a la tristemente célebre megaprisión del país, el Centro de Confinamiento para el Terrorismo, conocido como Cecot.

Exdetenidos del Cecot declararon a CNN que durante meses en la megaprisión fueron golpeados por guardias penitenciarios, recibieron disparos con perdigones, se les privó de atención médica adecuada y que se les negó el debido proceso.

El Cecot fue presentado por el Gobierno de El Salvador en 2023 como una megacárcel cuya principal función sería la de alojar a miles de miembros de pandillas, luego de una ola de homicidios que puso al país en un prolongado estado de excepción en seguridad.

Bukele propuso llevar a esta prisión a “lo peor de lo peor”, pandilleros a los que considera “terroristas”.

El Cecot está ubicado en una zona rural aislada y cuenta con un edificio destinado al confinamiento, una instalación para los perros guardianes, otra para los guardias y un estricto control de acceso con escáneres.

El edificio donde se aloja a los detenidos tiene capacidad para unos 40.000 presos, distribuidos en ocho instalaciones, con celdas de concreto, cerradas con gruesos barrotes de acero reforzado, que solo tienen camas metálicas escalonadas, pero no cuentan con sábanas ni colchones. Las celdas, que son comunitarias, tienen un retrete abierto, un lavabo de cemento y un cubo de plástico para lavarse. Hasta el agua que beben los presos es controlada por los guardias.

Los presos permanecen 23 horas y media al día en esas celdas, en donde no se permiten ni libros ni ningún otro elemento de entretenimiento. La comida se pasa a través de los barrotes y jamás incluye carne. Los 30 minutos que tienen fuera de la celda es para salir al pasillo central para hacer ejercicio o leer la Biblia.
