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.

Ninth Victim Recovered After Deadliest U.S. Avalanche in Decades

Rescue teams in California on Saturday recovered the body of the ninth and final victim of a deadly avalanche in the Sierra Nevada mountains, according to the local sheriff’s office.

The avalanche struck a group of 11 skiers and four guides on Tuesday as they were returning from a three-day backcountry trip near Castle Peak, a 2,777-meter (9,111-foot) mountain and popular tourist destination on the U.S. West Coast.

Six people were rescued alive on Tuesday. Authorities said the incident marks the deadliest avalanche in the United States since 1981.

“All nine individuals who lost their lives in the February 17 Castle Peak avalanche have been safely recovered from the mountain,” the Nevada County Sheriff’s Office said in a statement.

“There are no words that can truly capture the magnitude of this loss, and our hearts grieve alongside the families affected by this catastrophic event,” Sheriff Shannan Moon said.

Officials had warned on Thursday that search operations would likely continue through the weekend due to severe weather conditions in the area.

Survivors were able to call for help shortly after the avalanche occurred. However, near-zero visibility and the risk of additional snow slides prevented rescue teams from reaching them for several hours.

Trump Defies Supreme Court With New 10% Global Tariff

Defiant in the face of a judicial setback, Donald Trump on Friday imposed a new across-the-board 10% tariff after the Supreme Court of the United States ruled that he does not have the authority to levy customs duties under the guise of a national emergency.

The Republican president signed the order in the Oval Office and announced on social media that the measure would take effect “almost immediately.” According to a statement from the White House, the decree will formally enter into force on February 24 for a period of 150 days.

It remains unclear whether the new tariff will apply to countries that have already negotiated trade agreements establishing rates higher than 10%.

Earlier in the day, the conservative-majority court ruled that a 1977 law cited by Trump to abruptly impose tariffs on individual countries — disrupting global trade — “does not authorize the president to impose tariffs.”

Trump said he was “deeply disappointed” by the decision and accused some justices of being influenced by “foreign interests.”

Although he has made variable tariffs a cornerstone of his foreign policy, Trump acknowledged that it is uncertain whether the government will have to refund revenue already collected. A study by the University of Pennsylvaniaestimated that the amount at stake could reach as much as $175 billion.

“That issue was not addressed by the Court,” Trump told reporters, warning that the legal battle could drag on for “years.”

Justice Brett Kavanaugh, who dissented from the Court’s 6–3 majority opinion, cautioned that the legal process could become a “mess.”

Trump denied any error or haste in using tariffs as a policy tool, arguing instead that the six justices who ruled against him were motivated by “political correctness.” Vice President JD Vance wrote on X that the Court had acted “outside the law.”

U.S. Targets Members of Outgoing Boric Administration With Visa Revocations

The United States government announced on Friday the revocation of visas for three Chilean officials—whose identities were not initially disclosed—citing activities that allegedly “undermined regional security,” an accusation that Chile denies.

In a statement, the U.S. Department of State did not provide specific details about the individuals involved but criticized the outgoing administration of leftist President Gabriel Boric.

“The legacy of the Boric government will be further tarnished by actions that undermine regional security to the ultimate detriment of the Chilean people,” the statement read. It was signed by U.S. Secretary of State Marco Rubio.

Chile’s Minister of Transport, Juan Carlos Muñoz, later confirmed in a video message to the press that he is among those sanctioned.

“I was recently informed that my visa to enter the United States has been revoked by that country, which I deeply regret,” Muñoz said.

The U.S. statement also noted that Washington hopes to “advance shared priorities, including those that strengthen security in our hemisphere, with the upcoming Kast government.”

The electoral victory of ultraconservative leader José Antonio Kast was welcomed in Washington, which has been building alliances with like-minded governments in the region to reinforce its diplomatic and economic agenda—particularly in response to China’s growing investment presence in Latin America.

“We remain committed to promoting accountability for Chilean individuals who deliberately work to destabilize our hemisphere,” the statement concluded.
