In brief
The year 2024 showcased extraordinary scientific milestones, including the accidental discovery of a lost Mayan city and groundbreaking IVF techniques to save the northern white rhino. Amidst concerns about climate change, these uplifting stories remind us of the potential for innovation and discovery.
In a year marked by groundbreaking advances in science, 2024 has delivered a plethora of remarkable discoveries and innovations that inspire optimism about our future. Among the highlights are the unearthing of a lost Mayan city and a significant leap for wildlife conservation through successful IVF procedures for the endangered northern white rhino.One of the year's most captivating stories began when PhD student Luke Auld-Thomas stumbled upon a laser survey conducted for environmental monitoring. This accidental finding revealed the existence of an ancient Mayan city, named Valeriana, believed to have been home to around 30,000 to 50,000 people between 750 and 850 AD. Utilizing Lidar technology, archaeologists were able to locate monumental pyramids, sports fields, and amphitheaters that had long been obscured by the dense jungle canopy of Mexico. In a heartwarming development for conservation biology, scientists celebrated the first successful IVF pregnancy of a rhino embryo—an effort aimed at saving the nearly extinct northern white rhino. By implanting a viable embryo into a southern white rhino surrogate mother, researchers are making strides in reproductive technology, bringing newfound hope to preserving the genetic heritage of the northern white species. Although the surrogate tragically passed due to an infection, a thorough post-mortem revealed that the embryo was developing healthily, highlighting the potential for future successful IVF pregnancies.Additionally, this year provided the scientific community with exciting aerospace advancements, including Elon Musk’s Starship program, which achieved a world-first feat of using mechanical arms to catch a returning rocket booster. This pivotal moment could pave the way for more sustainable space travel, signifying progress towards reusable spacecraft.Alongside these triumphs, numerous studies showcased effective conservation strategies in reversing biodiversity loss, dispelling the notion that efforts to save endangered species are futile. These findings, emerging from a comprehensive ten-year review, confirmed that conservation actions had a successful impact in two-thirds of cases across diverse ecosystems.2024 also marked a spectacular total solar eclipse that captivated millions from North America, as cities experienced the awe-inspiring sight of the Moon completely covering the Sun—a rarity which unveiled the beauty of celestial mechanics.In another heartwarming story, new shoots have sprung from the beloved Sycamore Gap tree, which was cut down in 2023. Seeds and twigs were salvaged and nurtured by conservationists, symbolizing resilience and hope for local ecosystems.As 2024 progresses, these scientific achievements encourage us to remain hopeful about the potential of innovation to tackle environmental challenges while igniting excitement for future discoveries that shape our understanding of the planet.
