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.

Brazil offers to mediate Colombia-Ecuador tensions, calls for restraint

The government of Brazil has offered to mediate in the ongoing tensions between Colombia and Ecuador, while calling on both nations to exercise restraint.

In a statement released Wednesday, Brazil’s Ministry of Foreign Affairs urged the parties involved to act with moderation and seek a peaceful resolution to the dispute.

“Brazil encourages all sides to act with moderation in order to find a peaceful solution to the controversy. It stands ready to support dialogue efforts aimed at preserving peace and security in the region,” the statement said.

Brazil also expressed “serious concern” over reports of deaths in the border area between Colombia and Ecuador, noting that the circumstances surrounding the incidents have not yet been clarified.

The diplomatic move comes amid rising tensions between the neighboring countries, increasing regional concern over stability and security along their shared border.

U.S. lowers travel advisory for much of Venezuela but keeps high-risk zones under warning

The U.S. Department of State announced on Thursday that it has lowered its travel advisory for much of Venezuela to Level 3 (“Reconsider Travel”), reflecting what it described as improved security conditions in parts of the country.

However, the agency will maintain the highest Level 4 warning (“Do Not Travel”) for several regions, including the states of Táchira, Amazonas, Apure, Aragua and Guárico, as well as rural areas of Bolívar, citing ongoing risks such as crime, kidnapping and terrorism.

The updated advisory marks a shift from December, when the United States raised the alert for Venezuela to Level 4 nationwide, warning of severe security threats.

Despite the partial downgrade, U.S. authorities continue to urge caution, emphasizing that conditions remain volatile in certain areas and that travelers should carefully assess risks before planning any trips to the country.

EU lawmakers move to ban AI tools that generate non-consensual nude images

Members of the European Parliament are pushing to ban across the bloc artificial intelligence services that allow users to digitally “undress” people without their consent.

The proposal, adopted on Wednesday at committee level, aims to prohibit applications that generate non-consensual explicit images. Irish lawmaker Michael McNamara, one of the sponsors, said the measure seeks to stop tools that “have caused significant harm for the benefit of a few.”

Dutch MEP Kim van Sparrentak welcomed the move, calling it “a major victory, especially for women and children in Europe.”

The amendment, part of broader EU legislation on artificial intelligence, was approved by the Parliament’s civil liberties and internal market committees. It specifically targets systems that use AI to create or manipulate sexually explicit or intimate images resembling identifiable individuals without their consent.

The proposal will be put to a full vote in the European Parliament on March 26. If adopted, lawmakers and European Union member states will need to agree on a final version before it can take effect.

Separately, representatives of the 27 EU countries recently backed a Franco-Spanish amendment seeking to ban AI services used to generate non-consensual sexual images or child sexual abuse material.

The initiative follows controversy surrounding a feature introduced in Grok, developed by xAI, which allowed users to create simulated nude images from real photos. The tool sparked widespread criticism and prompted an EU investigation.

In response, xAI restricted image generation features in mid-January to paying subscribers and stated it blocks the creation of sexualized images in jurisdictions where such content is illegal.
