Advanced tools aiding investigations of Chile’s lost children

In Chile, families separated by decades-old adoption scandals and dictatorship-era disappearances are finally receiving long-awaited answers—thanks in part to advanced technological methods that are transforming forensic investigations. From satellite mapping to DNA databases and artificial intelligence, these tools are enabling a new wave of reconstruction and reunification.The search was initiated by the persistent enigma of children who disappeared during the political chaos in Chile. Numerous children were discreetly adopted overseas, frequently under the pretense of adoption or desertion, with parents being falsely told that their newborns had passed away.

Timekeepers may take unprecedented step as Earth spins more rapidly

El ritmo natural de nuestro planeta está transformándose, y los cronometristas globales lo están observando con atención. La Tierra gira con más velocidad que antes, lo que lleva a los científicos y a las autoridades internacionales de cronometraje a contemplar una modificación sin precedentes: restar un segundo al Tiempo Universal Coordinado (UTC).This possible measure, referred to as a "negative leap second," would be unprecedented in human history. Although leap seconds have been inserted to align clocks with Earth's somewhat inconsistent rotation, removing one poses intricate issues for technology, communications, and worldwide systems that depend on exact timing.For many years, measuring…

Breakthrough discovery reveals moths can hear plants — and steer clear of the loud ones

In a remarkable turn for our understanding of insect behavior, new scientific research has revealed that moths are capable of detecting acoustic cues from plants — and they appear to prefer quieter ones when choosing where to lay their eggs. This discovery shifts long-held assumptions about how insects interact with their environment and opens up new avenues of exploration in the field of ecological communication.The results of the study indicate that moths, rather than being mere travelers within the natural realm, are highly sensitive to the faint noises generated by the vegetation surrounding them. Moreover, their capability to "hear" appears…

Trump outlines AI plan targeting regulatory cuts and ‘bias’ concerns

Former President Donald Trump has announced a new artificial intelligence project that focuses heavily on reducing federal oversight and tackling what he terms political partiality within AI systems. As artificial intelligence quickly grows in numerous fields—such as healthcare, national defense, and consumer tech—Trump's approach marks a shift from wider bipartisan and global endeavors to enforce stricter scrutiny over this advancing technology.Trump’s newest proposition, integral to his comprehensive 2025 electoral strategy, portrays AI as a dual-faceted entity: a catalyst for American innovation and a possible danger to free expression. At the core of his plan is the notion that governmental participation…
