Beyond killer robots: China’s real AI threat to America is already here, experts warn
While Americans brace for a futuristic AI war of killer robots and bioweapons, experts warn ahead of President Xi Jinping’s U.S. visit this week that Beijing is already actively undermining America’s global supremacy through AI without ever firing a shot.
Experts who spoke with Digital outlined a stealthy, three-part playbook, which includes extracting the logic of American models, undercutting U.S. developers with free open-source software, and ultimately weaponizing those systems for things like cognitive warfare. They laid out how China bypasses billions of dollars in U.S. research through labs that interrogate cutting-edge American AI and copy its capabilities, while simultaneously flooding the global market with free alternatives.
«I think a ‘race’ is the wrong metaphor for this,» Leah Siskind, an AI research fellow at the Foundation for Defense of Democracies, told Digital. «I think it’s kind of like a multi-front war. And in some places, we’re winning and some places we’re losing.»
XI PREPARES CHINA ‘FOR BATTLE’ AS EXPERT WARNS OF GRAVE DANGER FACING US AHEAD OF DC SUMMIT
While top American tech firms have poured billions into building ultra-expensive, proprietary systems, China has focused heavily on distributing free, open-source models across the globe. Siskind warned that because American tech is costly and the U.S. sector has largely neglected open-source investment, many Fortune 500 companies are making the financial choice to run their operations on Chinese models—unwittingly opening the door to potential CCP censorship, hidden backdoors and, ultimately, global dominance.
«How can you compete with something that’s free when American tech is very, very expensive?» Siskind said. «How can we ensure that a Chinese open-source model would be truly clean, that it’d be truly free of CCP censorship? We can’t be—we just wouldn’t know. And that’s by design. We wouldn’t know what sort of trick backdoors might be implanted and how that could rear its head later on.»
Meanwhile, China expert Gordon Chang warned that Beijing is intentionally using these free models to repeat an economic tactic it previously deployed to corner a different industry.
«This is a tactic that China used with solar panels,» Chang told Digital. «Beijing sees that one day it will drive out the American models on cost and availability, and they will then dominate global AI.»
CHAD WOLF: CONGRESS HAS A CHANCE TO STOP CHINA FROM TURNING YOUR CAR INTO A CHINESE SPY
But to flood the market with free software, Beijing first needs the underlying technology—and a way to bypass America’s massive lead in computing power.
Chang noted that the U.S. possesses a commanding lead in physical infrastructure, boasting over 5,400 data centers compared to China’s roughly 450, along with far superior microchips. To work around the staggering hardware and energy costs required to train artificial intelligence from scratch, Siskind warned that Chinese labs are closing the gap through a process known as «knowledge distillation»—a method where a smaller model essentially interrogates a larger, smarter American model to copy its logic.
«They are able to leapfrog the process by kind of stealing this information,» Siskind said, pointing to the Chinese model DeepSeek as a prime example. «This is how they were able to release models like DeepSeek in 2025, which was seismic news because they were able to show that they were really competing with cutting-edge American models and had invested a fraction of the resources.»
US ADVERSARY TURNS UP THE HEAT ON AMERICA’S AI LEAD WITH AN UNDERESTIMATED EDGE
The threat is not theoretical. Just last week, the Department of Homeland Security issued a joint cybersecurity advisory warning that Chinese companies are conducting «industrial-scale knowledge distillation campaigns» to extract proprietary capabilities from U.S. frontier models.
Beyond economic undercutting and software theft, the experts also warned Beijing is simultaneously deploying artificial intelligence into physical supply chains and public influence campaigns.
Rather than sci-fi «killer robots,» Siskind emphasized that China’s immediate physical priority is «embodied AI»—embedding artificial intelligence into real-world infrastructure like factory automation, commercial drones, and autonomous supply chains. Meanwhile, Chang warned that AI-enhanced propaganda poses a direct threat to American decision-making and democratic sovereignty.
«They’re very good at cognitive warfare, and they can enhance their capabilities with artificial intelligence,» Chang said. «We do not want our elections determined in China. We do not want our critical national security decisions being made in Beijing. And that’s not impossible.»
CHINA EXPERT WARNS BEIJING WANTS AMERICANS — NOT THE CCP — TO SPREAD ITS MESSAGE
As President Xi Jinping arrives in the U.S. this week, the experts who spoke to Digital said the White House must treat these non-cinematic threats with the same urgency as traditional military posturing.
To protect America’s remaining edge, Siskind said Washington must tighten chip export loopholes, blacklist foreign labs engaging in deceptive distillation, and incentivize U.S. open-source development—emphasizing that «it is very important that the most advanced systems are developed under democracy and represent democratic values, as opposed to authoritarian values.»
CHINA-LINKED HACKERS INFILTRATED US GOVERNMENT NETWORKS BEFORE FBI TAKEDOWN
For Chang, the stakes of that technological defense extend far beyond standard economic competition.
«Xi Jinping throughout this century has been pushing the Chinese imperial-era notion of Tianxia, or ‘all under heaven’—that China’s rulers have a right to rule the world,» Chang warned. «That sounds ludicrous to us, but a Chinese regime powered by AI might actually be able to accomplish that. We certainly do not want our decisions being made in the Chinese capital.»
Addressing the United Nations General Assembly on Tuesday, President Donald Trump reiterated Washington’s goal of outpacing China, declaring that U.S. government documents will now refer to AI as «superintelligence.»
«The United States totally rejects any attempt to construct a globalist scheme to control the artificial intelligence being spoken of,» Trump told world leaders. «Whoever wins superintelligence wins. And we’re leading now over China by a lot and everyone else. And we’re going to keep it that way.»

Investigadores argentinos lograron reducir tumores de mama triple negativo en un estudio preclínico
Una proteína que ayuda a las células de un tumor de mama agresivo a crecer y a esquivar las defensas del organismo quedó bajo estudio como posible blanco para futuros tratamientos. Investigadores del Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) bloquearon esa proteína, llamada receptor H4 de histamina o H4R, en células tumorales y ratones.
Como resultado, los tumores crecieron menos y el sistema inmunitario respondió con mayor fuerza contra las células cancerosas.
El trabajo se publicó en la revista Frontiers in Immunology. Se trata de una investigación preclínica, es decir, realizada con células de ratón y modelos animales. Por lo tanto, todavía no se puede afirmar que este método funcione en personas con cáncer de mama ni que el compuesto utilizado sea seguro para pacientes.
La investigación fue liderada por Mónica Vermeulen, investigadora del CONICET y directora del Laboratorio de Células Presentadoras de Antígeno y Respuesta Inflamatoria del Instituto de Medicina Experimental (IMEX). El primer autor fue Ramiro Vázquez, integrante del mismo equipo.
Por qué el cáncer de mama triple negativo es difícil de tratar
El cáncer de mama triple negativo representa entre el 10 y el 15% de todos los casos de cáncer de mama. Se lo denomina “triple negativo” porque las células del tumor no tienen tres proteínas que suelen servir como objetivo de tratamientos: los receptores de estrógeno, los receptores de progesterona y la proteína HER2.
En otros tipos de cáncer de mama, los médicos pueden usar medicamentos que bloquean esas proteínas o hormonas para frenar el tumor. En el triple negativo, esas opciones no sirven porque las células cancerosas no tienen esos blancos. Por eso, los especialistas buscan otras proteínas que puedan atacar sin dañar en exceso a las células sanas.
El equipo del CONICET estudió el receptor H4R en células 4T1, un tipo de célula de ratón que se usa para investigar tumores con características parecidas a las del cáncer de mama triple negativo.
H4R es uno de los receptores de la histamina, una sustancia que el cuerpo produce de manera natural. La histamina participa, por ejemplo, en las reacciones alérgicas y en la inflamación. También cumple funciones en el estómago y el sistema nervioso. Para actuar, se une a receptores ubicados en las células. Uno de ellos es H4R, que aparece en distintos tumores mamarios.
El compuesto bloqueó una señal que favorecía al tumor
Los investigadores usaron un compuesto llamado JNJ-7777120, abreviado como JNJ. Su función es bloquear H4R. Dicho de forma simple, impide que la histamina active ese receptor y envíe señales a la célula tumoral.
Cuando trataron las células cancerosas con JNJ, observaron que se multiplicaban menos y perdían parte de su capacidad para moverse. Este segundo punto es relevante porque las células tumorales deben desplazarse para invadir otros tejidos y, en algunos casos, formar metástasis. La metástasis ocurre cuando el cáncer se extiende desde el tumor original hacia otros órganos.
El compuesto no eliminó las células tumorales. Lo que hizo fue detenerlas en una etapa previa a la división. En otras palabras, no las mató, pero redujo su capacidad para generar nuevas células cancerosas.
Además, el tratamiento redujo la producción de especies reactivas de oxígeno. Son moléculas que las células producen y que, en cantidades elevadas, pueden contribuir al crecimiento y a la supervivencia de algunos tumores. El bloqueo de H4R también modificó procesos metabólicos, es decir, la forma en que las células obtienen y utilizan energía.
“Nuestros hallazgos respaldan un papel protumoral de la histamina que actúa a través de H4R durante las primeras etapas de la tumorigénesis en células 4T1”, escribieron los autores. Esto significa que, en el modelo analizado, la histamina parece favorecer el desarrollo del tumor cuando se une a ese receptor.
Los tumores crecieron menos después de una sola exposición al compuesto
Luego, los científicos evaluaron qué ocurría en animales. Para eso, trataron las células tumorales con JNJ antes de inocularlas en ratones con un sistema inmunitario normal.
Una semana después, los ratones que recibieron células tratadas desarrollaron tumores más pequeños que los animales del grupo de control, que recibieron células sin exposición al compuesto. El efecto se mantuvo durante al menos dos semanas.
“Curiosamente, una sola dosis fue suficiente para inhibir el crecimiento tumoral durante al menos dos semanas”, indicaron los investigadores.
Este resultado sugirió que el JNJ no actuaba solamente sobre la célula tumoral. También parecía modificar la respuesta de las defensas del organismo frente al cáncer.
El efecto dependió del sistema inmunitario
Para comprobarlo, el grupo repitió la prueba en ratones RAG1. Estos animales no tienen linfocitos T y B funcionales, dos tipos de células esenciales para la inmunidad adaptativa. Se trata de la parte del sistema inmunitario que reconoce amenazas específicas, como una célula infectada o cancerosa, y dirige una respuesta contra ellas.
En esos ratones, el tumor creció de manera similar al del grupo que no recibió el compuesto. “El crecimiento tumoral en estos animales fue comparable al de los controles, lo que indica que la respuesta inmunitaria adaptativa desempeña un papel central”, señalaron los autores.
En los ratones con defensas normales, en cambio, el bloqueo de H4R aumentó la presencia de linfocitos CD8+ dentro del tumor durante la primera semana. Estos linfocitos son células que pueden reconocer y destruir células cancerosas.
A los 14 días, su cantidad ya era similar a la registrada en el grupo de control. Sin embargo, los linfocitos obtenidos de tumores tratados con JNJ mostraron mayor capacidad para eliminar células cancerosas.
Los investigadores también detectaron un aumento de interferón gamma, una proteína que participa en la activación de las defensas y en la respuesta contra infecciones y tumores.
Falta comprobar si el mecanismo se repite en pacientes
Vermeulen remarcó que los resultados todavía están lejos de una aplicación médica. “Son resultados alentadores que requieren estudios adicionales para determinar si pueden reproducirse en muestras humanas de pacientes con cáncer de mama triple negativo”, sostuvo.
El próximo paso será analizar tumores humanos para determinar si H4R tiene el mismo papel que mostró en el modelo de ratón. También será necesario establecer qué tipo de medicamento podría bloquearlo, en qué dosis y bajo qué condiciones podría resultar seguro.
Los investigadores indicaron que esta línea también puede ser de interés para otros tipos de tumores donde la histamina y sus receptores tienen participación, entre ellos los cánceres de colon, páncreas, ovario e hígado, además del melanoma.

There are two big differences between the previous Trump-era midterms and this year’s contest.
The first is the president’s approval rating, which is lower now than it was during President Donald Trump’s first term in 2018 or President Joe Biden’s term in 2022.
The second is Democrats’ generic ballot lead, which is wider and more enduring than it was in the 2018 «blue wave» election and much larger than the edge the GOP had in 2022.
Combined with Democrats’ candidate quality improvements and a Republican-led redistricting effort that could fall short of expectations, the House is likely out of reach for the GOP this year.
REPUBLICANS FACE BRUTAL MIDTERM HEADWINDS. SIX FORCES COULD HELP THEM DEFY HISTORY.
Then there’s a similarity: in all three elections, the Senate has been in play right up until the finish line.
In Trump’s first term, the Republicans ended up gaining two Senate seats despite a gloomy national environment. Four years ago, with inflation surging, the Democrats managed to add a Senate seat to their tally.
12 RACES SCRAMBLE SENATE BATTLEFIELD AS DEMOCRATS EYE COMEBACK
The Democrats have plentiful paths to 51 seats on election night. Republicans keep plowing money into six toss-up states, plus Kansas, and those efforts haven’t much moved the needle.
Yet the GOP’s paths to 50 are getting wider. That, plus a major update to the House forecast, in this week’s edition of the Power Rankings.
The Democratic Party has enjoyed a lead in the House all year. Now, as another 20 races shift leftward, this forecast sees the Democrats taking control.
THE BLUE WAVE LOOKS REAL UNTIL YOU LOOK A LITTLE CLOSER
Democrats have an advantage in at least 219 seats, while Republicans should hold on to at least 198 seats. There are 18 toss-ups on the board.
On a good night for the Democrats, the party will hold around 237 seats, or a gain of 22 from their current position. That’s because toss-up seats have mostly fallen in one party’s direction in previous elections.
POWER RANKINGS: FOR THE DEMOCRATS, WHERE COULD IT POSSIBLY GO WRONG?
(A «great night» for the Democrats, which would see the party take some Lean R seats as well, would mean a Democratic majority of up to 249.)
If the toss-up seats go the other way, the GOP could make life hard for the left. A good night for Republicans would see the party end up with around 216 seats. That’s two short of a majority but also leaves the Democrats with a mere two-vote cushion in the House.
In that scenario, a coalition of far-left Democrats, like the «Squad» of years past, could band together to put policy pressure on the next House speaker. That group is about to get bigger, thanks to the sure-thing victories of Democratic Socialists like Darializa Avila Chevalier and Claire Valdez.
Some of this week’s shifts are a product of polling. The Democrats’ generic ballot lead has pushed districts like Kentucky’s 6th District (Lexington and its suburbs) and Texas’ 15th District (Rio Grande Valley and Coastal Bend) away from the GOP.
The party’s strength in statewide races also plays a role, especially in Iowa (the 1st and 3rd districts, which contain the state’s biggest cities), and in Pennsylvania (three districts have shifted to the left, thanks in part to Governor Josh Shapiro’s coattails).
Other shifts are the result of Republican groups moving resources elsewhere, like from New York’s 19th District. Democratic Rep. Josh Riley lost this race by fewer than 5,000 votes four years ago, but as the GOP sends its money to more winnable races, it’s moving to Solid D.
A more surprising theme is also emerging: the GOP is in trouble with rural voters.
Sitting above Albany, New York’s 21st District contains some of the state’s most rural areas. Its voters delivered President Trump a 21-point victory over Vice President Harris two years ago. A survey last week had the Democratic candidate four points ahead of the Republican, 46%-42%.
DEMOCRATS SEE NEW CHANCES TO FLIP RED STATES — BUT A $400M GOP SPENDING ADVANTAGE COULD DERAIL THEIR PLANS
Maine’s 2nd District, which famously voted for President Trump three times in a row – and last time by nine points – is an open race this year after Rep. Jared Golden’s retirement. It was thought to be one of the best flip opportunities for the GOP. A new poll has the Democrat at 51% and the Republican at 45%.
Even Virginia’s 5th District, stretching across the Southside region and home to a two-thirds rural population, is a six-point race in a recent survey (45%-51% with the Republican ahead). The Democrat, Tom Perriello, was recently endorsed by Rep. Alexandria Ocasio-Cortez.
Gas, diesel and grocery prices are to blame. In dollar terms, the cost of living is higher in cities and suburbs, but voters across the country keep saying they are feeling the pressure of those increases and blame Republicans for them.
Iowa, for example, has experienced the fourth-highest gas price hike in the nation. Kentucky, Ohio and Texas are all in the top five states for diesel increases. That has proven tough for GOP candidates to counter.
New York’s 21st District moves from Solid R to Likely R. (Virginia’s 5th and Maine’s 2nd districts remain at Lean R and Toss-up, respectively.)
The Senate is still a toss-up with Democrats and Republicans taking 47 seats apiece. Six toss-ups are the most likely to determine control.
If Democrats win all six of those states, the party will take the majority with two seats to spare, for a total of 53. On the other hand, this forecast still sees a pathway for the GOP not to lose any seats. They’d accomplish that just by holding on to the same six states.
The toss-ups have largely been locked in through summer. There’s been a lot more movement in the «lean» categories (Kansas in, Georgia and North Carolina out). Collectively, you can think of these as the election night battlegrounds.
This week, a ninth state joins the list: Minnesota.
The North Star State has been on the political radar since Republicans recruited Michele Tafoya, the former NFL sideline reporter. She has deftly navigated her foray into politics by focusing on fraud, crime, and the cultural issues that animate GOP voters.
She also has a favorable matchup against Peggy Flanagan, Minnesota’s sitting lieutenant governor. It’s not clear whether Flanagan’s progressive politics or her proximity to the fraud issue is giving voters pause. Whatever the cause, there are signs that they are.
A new gold-standard survey shows 47% of likely voters support Flanagan, while 43% back Tafoya. Another 9% are undecided.
Republicans are fully united behind Tafoya, while 9-in-10 Democrats say they’ll support Flanagan’s bid. Independents are much less settled: 38% back Tafoya, 32% support Flanagan, and 29% haven’t decided.
Minnesota’s voter profile and election history suggest that there are some left-of-center voters in the «independent» column. They may be wavering on Flanagan now, then show up to vote for her on election day.
The Senate hopeful’s spot on the ballot next to Amy Klobuchar, the Democrats’ gubernatorial candidate and electoral over-performer, may also help push her over the line.
Either way, that poll can’t be ignored. Minnesota moves from Likely D to Lean D.

Pope Leo XIV arrived at Agostino Gemelli University Hospital in Rome for a procedure to remove a small node on his lung on Tuesday.
The 71-year-old pontiff said Monday that doctors discovered the nodule at a «very early stage» and recommended its removal. The surgery is not expected to last long, and the pope is expected to remain hospitalized for approximately one week, according to Vatican spokesman Matteo Bruni.
«Doctors found a small lump in the lung,» Leo said after an Angelus address at St. Peter’s Square on Monday. «It was identified at a very early stage and well situated.»

«The doctors consider it appropriate to intervene and so, following their advice, I decided to have surgery to remove it,» he continued. «The surgery is already scheduled for the next few days. I thank you for your spiritual closeness and I rely on your prayer.»
The surgery is likely to take place within a few days at the Gemelli Hospital in Rome, which is known as the «Pope’s» hospital, Vatican sources told Fox News.

In addition to addressing his health, Leo used his Sunday remarks to renew his appeal for peace in war-torn Ukraine, warning that the conflict continues to inflict suffering far beyond the country’s borders.
«The war in the martyred Ukraine continues to create suffering, even beyond its borders, especially in the poorest countries, where many people depend on the exports of cereals and grains,» the pope said.
