Secrets Uncovered: From Dino Bones to Younger Skin & Greenland's Origins

Scientists Explore Dinosaur Age Discrepancies Through Crocodile Bone Analysis; Skin Regeneration Research Advances

Researchers are exploring new methods to understand dinosaur growth and revitalize human skin, according to recent reports. Paleobiologist Anusuya Chinsamy-Turan at the University of Cape Town is using crocodile bones to re-evaluate dinosaur ages, while other scientists are studying rete ridges in skin to potentially reverse aging.

Chinsamy-Turan's research, detailed by NPR News on February 5, 2026, involves examining thin slices of crocodile bones. Her findings suggest that previous estimations of dinosaur ages may have been overinflated. "It changes how we think about dinosaur growth," she stated.

Meanwhile, Nature News reported on advancements in skin regeneration research. Scientists are focusing on rete ridges, structures in the skin that are difficult to study but may hold the key to stem cells needed for regeneration. Researchers have been studying animal models to find skin that closely resembles human skin, seeking clues about how these ridges form. The hope is that this research could eventually lead to methods for reversing skin aging.

In other news from Nature, an author correction was issued regarding a 2018 paper on cotranslational assembly of protein complexes in eukaryotes. Extended Data Fig. 4d was mistakenly presented as a partial duplicate of Extended Data Fig. 2a, with some strains misannotated. The corrected figures are now available, and the correction does not affect the results or conclusions of the study.

Separately, Time magazine reported on Donald Trump's interest in Greenland, which began in early 2018. During an intelligence briefing about rising Russian submarine activity and increased Chinese presence in the Arctic, Trump became focused on the idea that the U.S. needed a larger, more permanent presence in Greenland due to its strategic location. According to a senior White House official and another person familiar with the conversation, Trump believed Greenland's location in the North Atlantic was critical. In May of that year, Ronald Lauder suggested to Trump that the U.S. could leverage Denmark's economic struggles to acquire Greenland.
