Karla Ximena Vargas Berrones es Licenciada en Química, Magister en Planeación Estratégica e Innovación y Doctora en Ciencias Ambientales. Es investigadora y docente en la Facultad de Ciencias Químicas de la Universidad Autónoma de San Luis Potosí.
Su línea de investigación se enfoca en el desarrollo tecnológico de compuestos químicos sustentables y bioinsumos para disminuir la exposición y efectos adversos a la salud humana y ecológica por la exposición a contaminantes emergentes, así como ofrecer alternativas sostenibles y seguras para el uso de productos químicos domésticos e industriales.
Ha recibido varias distinciones por su trabajo; la más reciente, en 2024, es la beca L’Oréal-UNESCO para las Mujeres en la Ciencia en colaboración con la Asociación Mexicana de Ciencias. Este reconocimiento subraya su destacada contribución y compromiso con la investigación científica en el ámbito de la química y las ciencias ambientales.
1. ¿Cuál es tu área de investigación?
Mi trabajo se enfoca en la protección del medio ambiente a través de la ciencia y la tecnología. Investigo cómo restaurar ecosistemas dañados y cómo prevenir la contaminación antes de que ocurra. Actualmente, mi labor se divide en tres áreas clave: primero, identifico contaminantes peligrosos para evitar que afecten nuestra salud; segundo, desarrollo métodos para limpiar ríos, manglares y mares —especialmente tras derrames de petróleo— usando limpiadores orgánicos creados en mi laboratorio; y finalmente, diseño productos industriales seguros, como detergentes sustentables, que impulsan una economía más limpia y circular.
2. ¿Por qué te dedicas a ella?
Me apasiona innovar y crear soluciones reales que cuiden nuestro planeta. Para mí, la innovación no se trata solo de construir robots o viajar al espacio. Soy fiel creyente de que la innovación puede salvar al planeta desde lo cotidiano, no solo con grandes máquinas. Me motiva el reto de sacar los inventos del laboratorio y llevarlos a la industria, porque es ahí donde realmente transforman el mundo. Mi trabajo consiste en tender un puente entre el laboratorio y la industria para que los cambios lleguen a todos. Un ejemplo de esto son los detergentes que desarrollo: una respuesta directa a problemas globales como la contaminación del agua, protegiendo así nuestra salud y la naturaleza.
Al final del día, mi meta es crear soluciones que sanen nuestros ecosistemas y aseguren el bienestar de quienes habitamos en ellos.
3. ¿Has tenido alguna figura de referencia en tu trayectoria?
Mi familia es el pilar de mi trayectoria. De mis padres aprendí que construir una familia es el máximo trabajo en equipo: es sostener al otro cuando no puede y entender que, a veces, para lograr el 100 %, uno pone el 90 % y el otro el 10 % sin reclamos.
Ellos me enseñaron que, mientras la ciencia y los experimentos permiten segundas oportunidades, el tiempo en casa es irreversible. Mis hijos crecen solo una vez. He comprobado que cuando la vida personal está en equilibrio, la profesional despega; tener una red de apoyo sólida hace que cualquier desafío sea más fácil de superar.
4. ¿Qué te gustaría descubrir o solucionar en tu campo?
Creo firmemente que la contaminación del agua es uno de los desafíos más críticos de nuestra era. Aunque resolverlo por completo es una tarea compleja, atenderlo de forma integral puede generar cambios extraordinarios. Mi meta es que mis investigaciones ayuden a sanar nuestros ríos y mares desde dos frentes: primero, evitando la raíz del problema mediante la creación de detergentes sostenibles que no generen residuos tóxicos; y segundo, desarrollando técnicas naturales (biorremediación) para limpiar el agua que ya está dañada.
Pero la ciencia no basta por sí sola; también quiero transformar la conciencia de las personas. Hoy en día, muchos desconocemos que productos tan cotidianos como los detergentes pueden afectar gravemente nuestra salud y el entorno. Compartir este conocimiento me llena de satisfacción, pues estoy convencida de que, si todos aportamos nuestro grano de arena, lograremos un impacto positivo real en la salud de nuestro planeta.
5. ¿Qué consejo darías a quien quiera adentrarse en el mundo de la investigación?
Como corredora, encuentro en el maratón la analogía perfecta para la ciencia. Correr un maratón y hacer ciencia tienen algo en común: el muro del kilómetro 30. Ese momento donde el entusiasmo del inicio desaparece, la meta se siente lejana y piensas seriamente en rendirte. Pero en la pista, como en el laboratorio, la meta no se mueve; ella te espera. Si sigues avanzando —aunque sea paso a paso— vas a llegar. Muchos creen que la ciencia es éxito tras éxito, pero en realidad es la suma de muchos fallos superados. Al final, lo que separa a un científico que transforma el mundo de los demás no es su brillantez absoluta, sino su capacidad de mantenerse en movimiento cuando otros deciden parar.

Experts say cuts have hindered the response to DRC’s Ebola outbreak and resulted in ‘significant numbers’ of deaths
Elon Musk has an Ebola problem. SpaceX stock dropped precipitously after its initial public offering, and Tesla faces a wave of lawsuits. But instead of focusing on his companies, Musk has posted frequently on X about the US Agency for International Development (USAID), which he helped dismantle – or, in his words, feed into the woodchipper – last year.
“Elon’s USAID crash-out over the past week has been a thing to behold,” said Jeremy Konyndyk, a former top USAID official who oversaw the agency’s Ebola response in 2014-2015 and the president of Refugees International. “In a way, it’s helpful that Elon is doing this, because it’s putting attention back on the issue of what he did last year.”

Hidden in the gravitational waves generated by the largest black hole collision ever detected, clues retrieved by Australian National University (ANU) researchers have helped them observe how black holes drag spacetime itself along with their spin.
As two black holes collide, they merge in a massive cosmic impact, forming a larger black hole and creating ripples in spacetime called gravitational waves. In the largest black hole merger observed, GW250114, the ANU team discovered a hidden direct wave for the first time, a feature expected by general relativity and revealed in a recent paper published in Nature.
Some of the most intriguing objects in the universe, black holes have enormous power and effect on their surroundings, which scientists are still working to better understand. The gravitational waves produced by their collisions compress space as they travel, and highly sophisticated—and very precise—detectors are required to observe these waves, such as the United States’ Laser Interferometer Gravitational Wave Observatory (LIGO).
Since not even light can escape a black hole’s event horizon, gravitational waves’ ability to carry information about what lies just beyond the rim’s edge provides an important means of gaining perspective into one of a black hole’s most mysterious regions.
The most extreme black hole merger ever recorded, GW250114, came from a black hole perfectly positioned for Earth observers, allowing LIGO to capture faint signatures in the data. The team decoded the event’s direct wave, previously hidden in the data, revealing the black hole’s drag on spacetime.
In his theory of relativity, Albert Einstein described black holes as producing a “frame dragging” effect in which they pull nearby spacetime with them as they rotate, like water circling a drain. Also, according to general relativity, the region where this frame-dragging occurs, just past the event horizon’s edge, should produce gravitational radiation that creates a direct wave, imprinting information about the cosmic whirlpool surrounding the black hole.
Event horizons have been essential to theoretical physics models for decades, but very little observational data on them has been collected due to the difficulty of observing light that close to a black hole. Although not a physical object and instead merely a boundary in spacetime, general relativity posits that the event horizon’s properties, such as gravitational strength and rotational speed, should be measurable. Therefore, having access to a data source so close to the black hole’s edge, as with a direct wave, is extremely valuable to understanding our universe.
Due to the extreme nature of the event and our prime viewing location on Earth, the extremely powerful gravitational wave produced by GW250114 was the perfect opportunity to hunt for a direct wave. Despite longstanding predictions of direct waves based on general relativity, this is the first time that one has ever been detected, providing new insight into how fast the black hole is spinning and the gravitational power of the event horizon.
The researchers employed a new technique to isolate the subtle direct wave in the data from the rest of the event. This first success proves the case for direct waves and how to detect them, opening an entirely new avenue for investigating black holes. By finally detecting these waves, the team provides future researchers with an essential technique for designing new tests of General Relativity, as direct waves, horizon rotations, and surface gravity should all be linked.
Scientists currently grapple with the apparent incompatibility between general relativity, which describes our universe at the macro scale, and quantum physics, which operates at the smallest scales of matter and energy.
Some of our most essential technologies, such as GPS, lasers, quantum computers, and semiconductors, are designed according to these theories and operate perfectly despite the seeming contradiction of how these two perspectives of our universe describe physical reality.
The difficulty of reconciling these ideas is one reason scientists are interested in distant black holes. The extreme conditions of spacetime at the edge of an event horizon may offer the best clues for finally reconciling these existing theories, or for upending them altogether in favor of something that more accurately describes the physical universe at all scales.
The paper, “GW250114 Reveals Signatures of Post-Merger Black-Hole Horizon,” appeared in Nature on June 24, 2026.

Lego is amazing, and Lego Star Wars in particular. The fact that you can spend $1000 on a gigantic Death Star set is a clear sign it's not just for kids.
But there's a catch; Lego retires sets, meaning that, unless you're willing to pay silly prices on eBay, they're forever out of your reach. Oh, sure, Lego might need space for new sets, and stores likewise, but that's no excuse to rob builders of the best Lego Star Wars sets, especially with Star Wars' 50th anniversary next year.
I've rounded up the best deals on retired or retiring Lego sets. Some of these sets have been this price before Prime Day but don't count on them sticking around much longer.
Save $24 on this Lego model of the first ship you see in Star Wars, pursued by a Star Destroyer right after the opening crawl. View Deal
Save $42 on this Lego Star Wars Guard Gunship, a particularly cool variant of the Republic Gunship.View Deal
Get $10 off this Attack of the Clones troop carrier, which was bumped out by the Venator in Return of the Sith. View Deal
This isn't reduced but it's such an awesome set, a mini-sized model of the original trilogy's biggest vessel, you need this on your shelves. View Deal
Save 20% on the Galactic Empire's heavy-hitter, the Tie Bomber, complete with three minifigures. View Deal
Save $12.00 on this N-1 Starfighter, The Mandalorian's second favorite ship. It's been replaced by the far pricier UCS N-1 set but you can still grab this if you're fast. View Deal
Get $10 off the helmet worn by Captain Rex, a Clone Commander who managed to outlive many of his manufactured brethren. View Deal
This Clone Wars walker is another set that's not reduced but it's such a brilliant, play-friendly build that Lego should be ashamed for retiring it. View Deal

Star Wars' Clone Wars-era Republic Gunship may not be a miracle of practicaliy but I think it's cool as heck and that alone is reason enough to pick up this Lego Star Wars Coruscant Guard Gunship, $42 off for Amazon Prime Day.
Save $42 on this Lego Star Wars Coruscant Gunship set
The other reason? This set has already been retired by Lego meaning that not only are you saving big, this could be your last chance to buy the Lego Star Wars Coruscant Guard Gunship, before scalpers start selling it for silly money on eBay.
On top of looking seriously imposing, this Lego set has major play potential. You can swoosh it round the living room, loaded it up with the five included mini figures and accidentally drop Chancellor Palpatine because there's something off about that guy.
If this set isn't to your taste (maybe you're one of those evil Separatists), we've rounded up the Best Lego Star Wars sets. And don't forget to check out our other Prime Day deals.
Save $42 on this Lego Star Wars Guard Gunship, a troop-carrier which, on Coruscant, has been commandeered for Chancellor Palpatine's non-sinister agenda. View Deal
This is a real Prime Day deal double-whammy. Not only is this Lego Star Wars Coruscant Guard Gunship $42 off, the cheapest it has ever been, but as a retired set this could be your last chance to own it. Without paying silly money to eBay scalpers, that is; it's already sold out on Lego's website.
Not only does this set look good on a shelf, but it has got real potential, with opening and closing doors, firing missiles and a special handle to swoosh it around your living room!
It also boasts five minifigures: Three Clone Troopers, Chancellor Palpatine and Senator Padme Amidala. Go on, Padme, give Palpatine a push. It'll save you a lot of trouble in the long run.
If you love the Clone Wars era of Star Wars, this is a superb offer but you'll have to move fast.
Key features: 1083 pieces, builder's age 9+, 27.5 × 5.5 × 14.5 × 16 in. / 15 × 37 × 41 cm size
Product launched: September 2023
Price history: We've seen the price drop a little, but this is the lowest it's ever been and likely your last chance to buy it.
Price comparison: Amazon: $98
Reviews consensus: We loved the UCS Lego Star Wars Republic gunship, and this smaller model is also extremely cool, albeit with just five figures. Its Amazon reviews are near unanimous; few complain about the price tag and this price cut addresses that.
✅ Buy it if: You want a brilliant, play-friendly set to go with your other Clone Wars Lego sets.
❌ Don't buy it if: You're not a fan of the Clone Wars era. Instead, consider something like this Lego Star Destroyer, also reduced for Prime Day.
