From resurrecting extinct species to discovering genetic switches affecting anxiety, and enhancing emergency response with police drones, recent advancements underscore a significant leap in scientific and technological capabilities.
Colossal Biosciences, a US-based biotechnology company, has announced significant progress in its ambitious project to resurrect extinct species, starting with the woolly mammoth. The company revealed that it has successfully developed induced pluripotent stem cells, a crucial step in their de-extinction efforts. According to Eriona Hysolli, head of biological sciences at Colossal, and eminent Professor George Church, this achievement marks a milestone in potentially bringing the woolly mammoth back from extinction.
In related scientific developments, researchers from the University of Aberdeen in Scotland have discovered a genetic “switch” that significantly impacts anxiety levels in both humans and mice. This discovery could pave the way for new treatments for anxiety. The research team utilized CRISPR genome editing to identify a specific DNA enhancer, BE5.1, that regulates the brain-derived neurotrophic factor (BDNF) gene. Alterations to BE5.1 were found to increase anxiety in female mice, underscoring its vital role in managing anxiety.
Furthermore, a study detailed in Space Policy has underscored the necessity of informing space tourists about potential radiation risks from the sun, highlighting growing concerns in space travel safety.
Back on Earth, the UK is set to enhance its emergency response capabilities with the introduction of police drones as first responders, a move enabled by recent budget allocations. These drones are expected to provide critical information to police units at the scene, thus improving response times in emergencies. Additionally, intriguing research has shown that bumblebees can teach their counterparts to solve complex puzzles, showcasing the insects’ remarkable problem-solving abilities.
These advancements in science and technology, from de-extinction projects to genetic research and innovative emergency response methods, are covered in depth in the latest episode of the Tech & Science Daily podcast. Available on platforms such as Apple Podcasts and Spotify, the podcast offers detailed insights into these groundbreaking developments.
