2024 a breakthrough year for science: A look at some intriguing discoveries

As 2024 draws to a close, let's reflect on some of the most remarkable inventions and discoveries in science and technology. Oldest known Reptile skin: In 2024, researchers discovered the oldest fossilised reptile skin, dating back 20 million years, from a semi-aquatic creature, possibly Captorhinus aguti. DermaSensor for skin cancer detection: The DermaSensor, a noninvasive skin cancer detection device, uses light technology developed at Boston University to reduce missed diagnoses by half. Space cloud's impact on Earth's climate: About two million years ago, Earth’s solar system encountered a dense interstellar cloud that likely compressed the sun’s heliosphere, reducing Earth’s protection. BU space physicist Merav Opher, the study’s lead author, noted this is the first research to show how an external solar system encounter affected Earth’s climate.
