Tec de Monterrey honors one of its students for his contribution to nanotechnology in medicine

Guillermo Ulises Ruiz-Esparza is the first Mexican to be awarded the Pegasus Future of Health Technology award by the MIT Media Lab. The recognition is for his innovative contributions to medicine and nanotechnology.

Guillermo is a physician at the Monterrey Institute of Technology and Higher Education. He noticed the suffering caused by heart failure during his first encounters with his patients. That was the first step in creating nano-vectors to help fight this pathology.

His thesis on the use of nanotechnology to treat heart failure was written while he was at the Houston Methodist Hospital in Texas. At that time, nanotechnology was solely focused on oncological diseases.

And it was the perfect opportunity for him to propose an innovative idea: how nanotechnology vectors can carry drugs and be targeted to specific tissue. The heart was no exception. This research earned Ulises several awards, such as MIT’s TR35, the Harvard Pilgrim Healthcare Award, among others.

Ulises believes that the pandemic will help us better understand the importance of this technology. “Moderna, the company developing the COVID-19 vaccine, is implementing a method based on nanoparticles,” he said.

Besides his research and awards, this Mexican doctor and researcher intends to create a program that encourages young Hispanics to do research in Boston. His goal is to increase the number of Latin Americans in the field. The most important thing for Ulises is that his research will be useful in the future.

Former Trump allies call for removal, cite 25th Amendment amid Iran threats

Former allies of U.S. President Donald Trump on Tuesday called for his removal from office, arguing he is unfit to continue in the role following recent threats to “wipe out an entire civilization,” made just hours before the deadline of his ultimatum to Iran.

One of the most prominent voices was former Republican congresswoman Marjorie Taylor Greene, who invoked the 25th Amendment of the U.S. Constitution as a mechanism to remove the president from power.

“25th Amendment! Not a single bomb has fallen on the U.S. We cannot annihilate an entire civilization. This is evil and insanity,” Greene wrote on social media platform X.

Greene, once a leading figure within Trump’s political movement during his first term, broke with the president last November over disagreements on foreign policy and his handling of controversial cases.

Another former supporter, controversial commentator Alex Jones, also raised the possibility of applying the constitutional provision during his show, in a conversation with attorney Robert Barnes.

Barnes explained that invoking the 25th Amendment requires the support of two-thirds of Congress, making it a more complex process than impeachment.

Section 4 of the amendment, ratified in 1967, establishes that the vice president, together with a majority of the cabinet, can declare the president unable to perform the duties of the office, a decision that must then be confirmed by both chambers of Congress.

The statements come amid rising international tensions and increasing domestic political pressure on the president.

Trump pauses strikes on Iran, extends ultimatum by two weeks

The president of the United States, Donald Trump, announced a temporary suspension of attacks against Iran for a period of two weeks, extending the ultimatum he had imposed on Tehran just hours before its deadline.

According to the president, the measure is conditional on Iran allowing the “full, immediate, and secure” reopening of the Strait of Hormuz. Trump stated that the decision would involve a reciprocal ceasefire between both parties.

The announcement was made through a message on his social media platform, where he emphasized that the pause in military actions is intended to create space for de-escalation in the region.

He also noted that the decision followed a conversation with the prime minister of Pakistan, Shehbaz Sharif, who requested a two-week extension of the ultimatum.

The move comes amid heightened global tensions, marked by escalating threats and concerns over the potential impact of the conflict on key international energy trade routes.

WHO worker killed as Israeli forces fire on Gaza medical convoy

An employee of the World Health Organization (WHO) was killed on Monday in Gaza Strip after Israeli forces opened fire on a medical convoy transporting patients for evacuation, according to witnesses and official accounts.

The Israel Defense Forces (IDF) said the vehicle approached troops in a “threatening manner,” alleging that the driver accelerated toward soldiers despite warning shots. “The troops fired warning shots. The vehicle continued advancing, and additional fire was directed at it,” the military said in a statement.

The army also claimed the vehicle lacked clear markings and was therefore treated as a potential threat.

However, survivors disputed that account. Raed Aslan, a passenger in the convoy, told reporters in Khan Younis that the vehicles were clearly marked with WHO insignia. “The vehicle was clearly identified as belonging to the WHO,” he said, adding that an Israeli tank blocked the road and fired at the driver despite the route being empty.

The convoy was transporting patients to the Rafah crossing, the only exit point available for medical evacuations abroad, as Israel does not permit transfers to Jerusalem or the West Bank.

The incident adds to a series of controversial cases involving Israeli military actions against humanitarian convoys. In April 2024, seven workers from World Central Kitchen were killed in an Israeli strike in Deir al-Balah. The military initially cited a “misidentification,” despite the vehicles being clearly marked.

Similarly, in March 2025, 15 paramedics, rescuers, and a UN worker were killed near Rafah. Israeli authorities first claimed emergency lights were off, but video evidence later contradicted that assertion.

A subsequent investigation by organizations including Forensic Architecture found that Israeli forces fired hundreds of rounds at the convoy, and that the vehicles were later destroyed and buried along with the bodies before being recovered days later.

The latest incident is likely to intensify scrutiny over the conduct of military operations in Gaza, particularly regarding the safety of humanitarian personnel and medical evacuations.
