Con la renegociación del Tratado entre México, Estados Unidos y Canadá en puerta, el Gobierno de la presidenta mexicana, Claudia Sheinbaum, ya tenía un desafío este año en su relación con la administración de su homólogo estadounidense, Donald Trump. Sin embargo, el panorama se le ha complicado más en solo unas cuantas semanas, debido a la entrada al juego de otro factor que con frecuencia genera tensiones entre ambos países: la seguridad y el combate al crimen.

El primer hecho que abrió otro frente para el Gobierno de Sheinbaum fue la revelación sobre la presencia de agentes de la Agencia Central de Inteligencia de Estados Unidos (CIA, por sus siglas en inglés) durante un operativo en el estado de Chihuahua, en el norte de México, para desmantelar laboratorios clandestinos de drogas.

La Fiscalía de Chihuahua informó el 19 de abril que dos estadounidenses, a quienes identificó como instructores de la Embajada de ese país, murieron junto con dos funcionarios mexicanos en un accidente automovilístico cuando regresaban de esa operación antidrogas en el municipio de Morelos.

CNN y otros medios confirmaron días después que los fallecidos eran dos agentes de la CIA que trabajaban con autoridades mexicanas en operaciones contra el narcotráfico.

Desde que se dio a conocer la muerte de estas personas, Sheinbaum lamentó lo sucedido pero, al mismo tiempo, dijo que su Gobierno no estaba enterado de su presencia en territorio mexicano y reclamó al Gobierno de Chihuahua por la situación. Incluso, señaló que debe investigarse si hubo una posible violación a la Ley de Seguridad Nacional, que establece límites a la cooperación entre funcionarios mexicanos e instancias internacionales.

Pero no solo eso. Sheinbaum también aseguró que pediría explicaciones al embajador de Estados Unidos, Ronald Johnson, e insistió en que su Gobierno no tolerará vulneraciones a la soberanía de México.

José Luis Valdés Ugalde, académico del Centro de Investigaciones sobre América del Norte de la Universidad Nacional Autónoma de México, dijo a CNN que este episodio apunta cuando menos a dos escenarios. El primero, que el Gobierno de Chihuahua probablemente tenía trato directo con los agentes de la CIA, aunque la gobernadora María Eugenia Campos lo niegue. El segundo, que algunas autoridades de Estados Unidos desconfían del Gobierno de México.

“Eso de que lo hayan hecho por la esquina, por el lado chihuahuense, estatalmente hablando, sin necesidad de recurrir al Gobierno federal, habla de la muy mala relación que México tiene con Estados Unidos en términos de los grupos de inteligencia que participan en los operativos o no participan en los operativos mexicanos en contra de los cárteles”, expuso.

A la fecha, tanto la Fiscalía General de la República (FGR) como la Fiscalía de Chihuahua tienen investigaciones abiertas para determinar bajo qué parámetros se produjo la presencia de los agentes de la CIA en el país.

A las tensiones causadas por la presencia de agentes de la CIA se sumó otro elemento esta semana.

El Departamento de Justicia de Estados Unidos publicó este miércoles una acusación formal en contra del gobernador del estado de Sinaloa, Rubén Rocha, así como de otros nueve funcionarios y exfuncionarios, a quienes atribuye delitos de narcotráf

New York (CNN) — The Department of Defense announced Friday an agreement with seven major technology companies to use their artificial intelligence tools in its classified networks.

Not included: Anthropic, which the Trump administration has blacklisted over Anthropic’s insistence that the Pentagon include certain safety guardrails for the government’s use of AI in warfare. But the White House reopened discussions with Anthropic in recent weeks after the company made significant announcements about several technology breakthroughs.

The companies involved in the deal: Elon Musk’s SpaceX, ChatGPT-maker OpenAI, Google, Microsoft, Nvidia, Amazon Web Services and Reflection. The Pentagon has existing AI contracts with several companies, including Palantir and OpenAI.

Signing so many of Anthropic’s competitors could give the Trump administration some leverage. Anthropic is missing out on substantial revenue that its competitors have access to. Last year’s One Big Beautiful Bill Act included a large sum of money for the Pentagon to spend on AI and offensive cyber operations. Tech companies have been jostling for that money.

The companies’ AI tools will be used for “lawful operational use,” the Pentagon said, and the new agreements will transform the military as an “AI-first fighting force and will strengthen our warfighters’ ability to maintain decision superiority across all domains of warfare.”

The Pentagon also pointed to the success of its GenAI.mil platform, saying 1.3 million DoD personnel have used the service.

Until recently, Anthropic’s Claude was the only AI model available in the Pentagon’s classified network. But President Donald Trump announced the administration would sever ties with the company after Anthropic refused to back down on terms that would allow the military to use Claude for “all lawful purposes,” including autonomous weapons and mass surveillance.

The Pentagon declared Anthropic a “supply chain risk,” a label only used in the past for companies associated with foreign adversaries. It could effectively blacklisted Anthropic from the government. Anthropic sued the Trump administration in response, and a federal judge in California last month blocked the government’s effort.

But Anthropic CEO Dario Amodei visited the White House last month for a meeting with Chief of Staff Susie Wiles after Anthropic unveiled its Mythos tool that can identify cybersecurity threats – but also present a roadmap for hackers to attack companies or the government.

(CNN) — Tens of thousands of young children are injured every year by common household items that many parents don’t think to lock away.

More than 240,000 children ages 5 and under were treated in US emergency departments for injuries related to household cleaning products over a 16-year period, according to estimates published in a large, new study in Pediatrics.

Young children are especially at risk since they can’t read or understand warning language, but the steps parents and caregivers should take to keep children safe are easy and straightforward.

I spoke with CNN wellness expert Dr. Leana Wen, an emergency physician and adjunct associate professor at George Washington University, to get her guidance. She previously served as Baltimore’s health commissioner and is the mother of two young children.

CNN: What did this study find about injuries linked to household cleaning products?

Dr. Leana Wen: This study analyzed national emergency department data over a 16-year period, from 2007 through 2022, focusing on unintentional injuries among children 5 and under. The researchers used a federal surveillance system that tracks consumer product–related injuries across the United States.

They estimated that 240,862 young children were treated in emergency departments for injuries related to household cleaning products during that time. The majority of these cases, almost 60%, involved ingestion, meaning the child swallowed the product. Nearly 40% were through contact, and a small percentage, 1.2%, involved inhalation.

CNN: What types of cleaning products are most commonly involved?

Wen: Two types of products stand out: Bleach accounted for about 30% of injuries, and laundry and dish detergents for nearly 29%. In terms of how products were packaged, detergent packets were linked to about one-third of injuries, spray bottles to just over one-quarter, and other containers, such as bottles or open containers, made up a smaller but still substantial portion.

Bleach has remained a consistent source of injury over time, in part because it is widely used in many households and often stored in places accessible to children. Detergents are also a major contributor, especially with the introduction of concentrated products like laundry and dish detergent packets that are small and brightly colored and often resemble candy, which can make them particularly appealing to young children.

CNN: What kinds of injuries are most common, and how serious are they?

Wen: Poisoning accounted for about 64% of diagnoses, according to the study. Other common diagnoses included chemical burns, which made up about 14%; and skin or eye irritation, including dermatitis and conjunctivitis, at around 11%.

About 7% of children in this study required hospitalization. Of these cases, approximately 84% involved ingestion, and nearly half of hospitalized children were 1 year of age or younger.

These statistics underscore that injuries involving household products can be very serious. These cleaners are designed to break down grease and stains and to destroy bacteria, and those same properties that make them effective can damage human tissue.

It’s also important to note that the results do not include children who were treated at their pediatrician’s office or an urgent care facility, which means the total number of cases involving exposure to household products is probably much higher. The authors reported there were

(CNN) — From almost any other country, the answer would have been a firm no. But when the United Arab Emirates came under a relentless Iranian attack during the US-Israeli war on Tehran, Israel agreed to deploy one of its most sensitive military systems.

Prime Minister Benjamin Netanyahu secretly ordered the Israeli military to send an Iron Dome interceptor battery – and soldiers to operate it – to the UAE after a call with President Sheikh Mohammed bin Zayed Al Nahyan, a move that demonstrates just how far ties have come.

Now, as the UAE distances itself from its traditional allies because of their stance on the Iran war, Israel sees an unprecedented opportunity to further strengthen its ties, several Israeli officials have told CNN.

The UAE, which in 2020 became the first Arab nation in 26 years to normalize ties with Israel under the Abraham Accords, has said the Iran war could reshape its regional alliances, citing disappointment with some of its closest Arab partners. Abu Dhabi would instead become closer to Israel and nations that supported it during the war, including France, the United States, and the United Kingdom, officials say.

“Amid the limited positive developments to emerge from the Iran war, this relationship (with Abu Dhabi) stands out as ‘good news,’” an Israeli source with close knowledge of relations with the UAE told CNN. “Ties have advanced to a new level, including at the leadership level.”

UAE officials and state-linked commentators have in recent weeks issued rare public rebukes of Arab nations for failing to step up as the country bore the brunt of Iran’s attacks during Tehran’s retaliation in the US-Israeli war.

The stance of fellow Gulf Arab monarchies “was the weakest historically,” Anwar Gargash, an adviser to the UAE president, said at a conference in Dubai this week.

“I expected it from the Arab League and I’m not surprised,” Gargash said, referring to the bloc of 22 Arab states. “But I did not expect it from the Gulf (states), and I am surprised.”

As criticism mounted that Israel and the United States had drawn the Gulf into a war most regional states opposed, Gargash doubled down on the need for ties with both, telling CNN that “Israeli influence (will) become more prominent in the Gulf, not less.”

Israel “did not even envision this closeness when we signed the Abraham Accords,” an Israeli diplomatic source told CNN, referring to the deepening military ties.

“The war brought an unprecedented level of closeness, driven largely by a shared sense of fate – both countries were attacked and the enemy is common,” said another Israeli official. “This will definitely be reflected in the expansion of relations from here on.”

This week, the UAE pulled out of the OPEC oil cartel after nearly six decades of membership. Asked by CNN if the group’s de facto leader, Saudi Arabia, was consulted on the move, UAE Minister of Energy Suhail Al Mazrouei said it was a “sovereign national decision.”

Experts say that while the UAE had felt constrained by the group and had been seeking to exit for years, it chose to remain in deference to Saudi Arabia.

The Israeli official who spoke to CNN cast Abu Dhabi’s departure from OPEC as evidence of a widening gap with Gulf positions and shift toward closer alignment with Israel and the US.

“It increases the UAE’s distance from traditional Gulf policy and transforms them into something entirely different in the region and for Israel,” the official said, adding that the UAE “found themselves alone – and Israel and the United States were there for them.”

(CNN) — Human children often copy their friends’ preferences for toys or clothes, while adults are prone to jumping on popular diets or lifestyle trends. Now it turns out that this sort of imitation is not unique to our species, as wild parrots learn to try new foods by copying their peers, a new study suggests.

Animals living in urban environments often encounter new or unusual resources, such as garbage, street trees, exotic plants or invasive species.

For animals in these ever-changing cityscapes, expanding their diet to include novel food items can be crucial, according to the study published in the journal PLOS Biology on Thursday.

However, they are often wary of trying unfamiliar food, as it could be poisonous to them or carry parasites, said the researchers in Australia, Germany, the US and Switzerland.

One tool some animals use to find out whether it’s worth taking the risk is social learning, which they do by observing or interacting with others or their items.

This strategy has been seen among wild jackdaws and wild rooks. Lab studies on rats in Norway have also shown that rats can acquire food preferences by smelling the breath of clued-up individuals.

However, social learning strategies have been little studied in the wild compared to labs, according to the researchers.

To find out if wild parrots use the technique, the researchers studied more than 700 wild sulphur-crested cockatoos across five roosting communities in central Sydney.

Two parrots from a Balmoral Beach community and two from a Clifton Gardens community were trained –– after being initially very averse –– to eat almonds that were artificially dyed either blue or red, respectively.

Then, a food dispenser containing both colored almonds was introduced into the communities in daily sessions for 10 days.

After seeing the trained parrots take them, curious individuals started eating the colored almonds in the Balmoral Beach community within seven minutes, and in the Clifton Gardens community in less than one minute, according to the study. In both roosts, the parrots ate both colors from day one.

In a third community, where there were no trained cockatoos, it took four days for the parrots to try the novel food items. But after one parrot –– who had moved from the Balmoral Beach community, where she had watched others eat them 130 times –– took the risk, 15 other parrots also ate the almonds within 10 minutes.

The researchers expanded the experiment to include two more roosts.

By the end of the 20-day experiment, 349 individuals across five communities were eating colored almonds, according to the study.

Young parrots are ‘very conformist’

The researchers also looked at whether the parrots were selective in who they copied and found “a clear sex bias,” lead study author and behavioral ecologist Julia Penndorf, a postdoctoral researcher at the University of Exeter in the UK , told CNN on Thursday.
