Continúa la certidumbre en México. Con motivo de la actual revisión del T-MEC, la presidenta @Claudiashein reafirma que nuestro país busca las mejores condiciones para fortalecer el contenido regional. El tratado mantiene vigencia hasta 2036.
1,000 days since the October 7 massacre.
1,000 days since some people also lost their moral compass and chose to portray those atrocities as “resistance.”
What makes something alive? We simply don't know, but synthetic biologists are a step closer to providing an answer thanks to SpudCell, the most sophisticated attempt at creating an artificial life form yet https://t.co/v5E4eiHmtz

Scientists made 50-year-old skin cells behave like they’re 20 again.
Researchers at the Babraham Institute in Cambridge have developed a groundbreaking method to reverse the biological aging of human skin cells by approximately 30 years, all while keeping them as fully functional adult skin cells.
The team used a carefully controlled, short-term version of the Nobel Prize-winning Yamanaka reprogramming technique. By exposing adult skin fibroblasts to a specific set of reprogramming factors (the Yamanaka factors) for just 13 days—and then stopping the process early—they successfully “reset” many molecular markers of aging without pushing the cells all the way back to a stem cell state.
After this brief treatment, the rejuvenated cells displayed a dramatically younger profile: their epigenetic clock (a measure of chemical tags on DNA that tracks biological age) and their gene expression patterns (the transcriptome) closely resembled those of cells from much younger individuals.
Even more impressively, the cells behaved younger too. The treated fibroblasts produced significantly higher levels of collagen—the protein essential for skin firmness, elasticity, and wound healing—and they migrated faster to close an artificial “wound” in laboratory dishes compared to untreated older cells.
The researchers also observed reversal of age-related changes in genes associated with diseases such as Alzheimer’s and cataracts, suggesting the technique could have broader therapeutic implications.
While this work is still in its early stages and the precise mechanisms remain under investigation, the findings open exciting possibilities: one day, scientists may be able to selectively rejuvenate aging cells in the body to enhance tissue repair, improve healing, and potentially slow or mitigate some effects of age-related diseases—without the risks associated with fully reprogramming cells into stem cells.

Meet Tsunami.
Tsunami is a nine year old Border Collie. His final search and rescue mission followed two powerful earthquakes that struck Venezuela just 39 seconds apart on June 24. The magnitude 7.2 and 7.5 quakes caused nearly 800 buildings to collapse trapping many people under rubble made of concrete and steel. By June 29 the death toll had climbed to at least 1719.
Working with his handler Jorge Beens Tsunami navigated unstable debris piles in search of survivors. His exceptional sense of smell allowed him to detect faint human scents carried in tiny plumes through cracks in the wreckage. Upon locating someone he would bark or assume a specific trained alert posture to guide rescue teams to the most promising areas.
According to K SAR ECID Tsunami contributed to the rescue of at least 13 people during this deployment.
His background makes this accomplishment even more inspiring. Originally rescued from abuse and abandonment on the streets of Caracas Tsunami caught the attention of Beens who recognized his sharp intelligence and strong natural tracking instincts. Beens adopted him and provided specialized training for urban search and rescue operations.
Throughout his career Tsunami supported response efforts after major earthquakes in Turkey and Syria as well as landslide incidents in Venezuela.
This latest mission stood apart from the rest. After years of demanding deployments and extensive work in hazardous ruins Venezuelan authorities and his handler designated it as Tsunamis final official operation before retirement.
Sometimes the animals we rescue go on to rescue us in return.
La presidenta Claudia Sheinbaum aseguró que es seguro visitar México, luego de la alerta de viaje emitida por Reino Unido por el partido entre México e Inglaterra. Sostuvo que el país ha recibido visitantes durante toda la Copa Mundial sin mayores problemas.
Además, informó que el Gobierno de la Ciudad de México reforzará las medidas para evitar aglomeraciones en Paseo de la Reforma y llamó a los aficionados a actuar con responsabilidad y evitar el exceso de alcohol.
