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.

Ukraine declares nationwide energy emergency amid russian attacks and extreme cold

The Ukrainian government on Wednesday declared a nationwide energy state of emergency amid continued Russian military attacks and extreme winter weather, with nighttime temperatures dropping as low as minus 18 degrees Celsius.

“The consequences of Russian attacks and worsening weather conditions are severe (…) Overall, a state of emergency will be declared for Ukraine’s energy sector,” Ukrainian President Volodymyr Zelensky said in a statement posted on social media following a meeting with senior officials.

Zelensky announced the creation of a “permanent coordination headquarters” to manage the crisis in the capital, Kyiv, and tasked former defence minister and current energy chief Denys Shmyhal with overseeing support efforts for affected individuals and communities, including addressing power outages, heating shortages and other “practical issues.”

“There are many problems that require urgent solutions,” the president said, noting that repair crews, energy companies, municipal services and the State Emergency Service are working “around the clock” to restore electricity supplies. Kyiv has been particularly affected after Russian strikes last Friday disabled key parts of the power grid, as daytime temperatures hover around minus 12 degrees Celsius and plunge to minus 18 at night.

Zelensky added that public authorities will “maximize efforts with partners to obtain the necessary equipment and additional support,” while the government will ensure “maximum deregulation of all processes” to speed up the connection of backup power equipment to the grid. He also confirmed that work is underway to significantly increase electricity imports into Ukraine.

The Ukrainian leader further instructed his Cabinet to review curfew regulations in light of the extreme cold, arguing that citizens must have the greatest possible access to assistance centers, while businesses should be given flexibility to plan their operations according to the state of the energy system.

France joins Denmark’s ‘Operation Arctic Resistance’ in Greenland amid U.S. tensions

French President Emmanuel Macron confirmed in the early hours of Thursday (Wednesday afternoon in El Salvador) that France will take part in “Operation Arctic Resistance,” after Denmark announced it would expand its military presence in Greenland amid rising tensions with the United States over Washington’s stated ambitions regarding the semi-autonomous territory.

“At Denmark’s request, I have decided that France will participate in the joint exercises organized by Denmark in Greenland, ‘Operation Arctic Resistance,’” Macron said in a brief message posted on social media at 5:18 p.m.

The French president added that “the first French military elements are already on their way, with others to follow,” though he did not specify the number of troops being deployed or the scale of France’s planned contribution.

The governments of Sweden, Norway and Germany have also confirmed the deployment of military contingents to Greenland. Germany’s armed forces will send a 13-member reconnaissance team to the Greenlandic capital, Nuuk, to take part in a mission scheduled to run from Thursday through Saturday, according to the German Ministry of Defence.

Denmark’s announcement came shortly before a Danish delegation met at the White House with U.S. Vice President JD Vance and Secretary of State Marco Rubio to discuss Washington’s plans regarding Greenland. Copenhagen said the military activities would be carried out “in close cooperation with NATO allies.”

Iran closes airspace amid U.S. threats and deadly nationwide protests

Iranian authorities closed the country’s airspace in the early hours of Thursday, according to data from flight-tracking website FlightRadar24, amid growing threats of a possible U.S. attack as protests across the country continue and have reportedly left thousands dead.

According to FlightRadar24, the Iranian government suspended all flights to and from the country, except for international flights that have received special authorization. The notice was initially issued for a duration of just over two hours.

The move comes after U.S. President Donald Trump in recent days threatened to strike Iran if its security forces failed to halt the deaths linked to weeks-long protests that began in Tehran and later spread to other Iranian cities. Despite the threats, the White House said diplomacy remains Trump’s preferred option.

Speaking from the Oval Office on Wednesday, Trump claimed that “the deaths in Iran have stopped” and said there would be no executions of protesters following his warnings to Tehran. He added that his administration would seek to verify those claims.

“I’ve been told the deaths in Iran are stopping. They’ve stopped, and that there are no plans for executions,” Trump told reporters, cautioning that the United States would be “very upset” if those assurances proved to be untrue.

The statements contrast with reports from rights groups. The Norway-based NGO Iran Human Rights (IHRNGO) said on Wednesday that more than 3,400 people have been killed since the protests erupted. Meanwhile, Kurdish-Iranian rights group Hengaw reported this week that a 26-year-old Iranian man, Erfan Soltani, was facing execution as of Wednesday.
