Rapid DNA

A new analysis by Epoch AI finds the cost of achieving a given level of AI model performance has dropped roughly 13-fold per year over the past five years. That decline is faster than historical cost curves for computing hardware, lithium batteries, DNA sequencing and electricity. The authors caution, however, that these steep efficiency gains may not continue indefinitely, prompting discussion about how long such rapid deflation in AI costs can last.

Arkansas has introduced Rapid DNA technology at a booking station, allowing law enforcement to process DNA samples quickly during arrests rather than waiting days or weeks for lab results. Officials say the technology can speed up identifications and help connect suspects to other cases sooner. Local coverage highlights it as a step toward modernising booking procedures in the state.

New research reported by Earth.com suggests transposons, so-called jumping genes, may explain how ants diversified rapidly after the dinosaurs went extinct 66 million years ago. The finding points to these mobile DNA elements driving genetic variation that allowed ant species to adapt and spread into many ecological niches, helping make ants one of the most successful insect groups on Earth.

SpaceX's Starship program is being described as a winning bet, even as reports highlight a cultural and institutional clash between SpaceX and NASA. The story frames SpaceX's aggressive, risk-tolerant development approach against NASA's more cautious engineering culture, arguing that the gamble on rapid Starship testing has paid off despite tensions with the space agency.
