DNA: the double helix that stores life’s instructions
Three men face burglary charges connected to a Whaley Bridge incident in Derbyshire. Marcus Smith died after a homeowner discharged a legally held firearm when confronted by intruders. A second man was injured and treated in hospital. The CPS has decided no charges will be brought against the homeowner in relation to Smith’s death.
Tech leaders have urged lawmakers to require DNA and RNA vendors to screen orders for dangerous sequences. The open letter argues faster, cheaper AI tools may ease misuse, and calls for traceable records of purchases amid rising biosecurity concerns.
Researchers report a lab-made, membrane-bound system called SpudCell that can feed, grow, replicate genetic material, and divide. The work demonstrates a complete cell-like cycle in a synthetic chassis, using viral components for replication and translation, and points toward future modular engineering while acknowledging remaining challenges.
Researchers have detected erythrulose, a four-carbon sugar, in the interstellar medium near the Milky Way’s center. The finding supports theories that sugars essential to life could form in space and arrive on Earth via comets and asteroids. The study, published in Nature Astronomy, suggests that millions of tonnes of erythrulose may have rained down on Earth during the Late Heavy Bombardment.
