AI Creates Office "Workslop" Crisis
A study by researchers at Stanford and BetterUp found that 40% of US workers had received "workslop" - AI-generated content that looks passable but lacks substance - in the past month. This forces colleagues to spend extra time decoding, correcting, or redoing the work entirely.
The problem extends beyond productivity loss. More than half of workers viewed AI-using colleagues as less creative, while 42% saw them as less trustworthy. One finance worker described having to decide whether to rewrite AI content herself or "just call it good enough."
This comes after an MIT study found that 95% of US companies had reported no meaningful revenue growth since implementing AI. BetterUp vice president Kate Niederhoffer: “Employees are using AI tools to create low-effort, passable-looking work that ends up creating more work for their coworkers.”
JD Sports Blames "Strained" Consumers for Profit Drop
JD Sports reported a 13.5% fall in adjusted profits to £351m as the sportswear retailer blamed "strained consumer finances" for declining sales across all regions.
North America, JD's biggest market, accounting for 39% of its £5.94bn sales, suffered the worst performance with a 3.8% drop. The UK fell 3.3% to £1.46bn as the company reduced its store count by 13 locations to optimise shop sizes and locations.
The retailer expects limited impact from Trump's tariffs, with direct exposure accounting for less than 10% of US sales. However, this protection comes partly from buying stock before tariffs took effect, raising questions about future costs. Charles Stanley chief investment commentator Garry White: “It’s going to be a tricky second half at JD Sports Fashion. Consumers are cautious – especially in the UK.”
Scientists Create AI-Designed Killer Viruses
Stanford researchers used AI to design 302 new viruses from scratch, with 16 successfully infecting and killing bacteria in laboratory tests, marking the first time artificial intelligence has created functioning genomes.
The AI model called Evo, trained on millions of bacteriophage genomes, designed viruses that outperformed natural ones at killing E. coli bacteria. Some AI creations were so distinct that they would be classified as new species.
The breakthrough raises serious biosecurity concerns. Experts warn the technology could be misused to create bioweapons, though researchers emphasise the potential for developing new therapeutics against bacterial infections. J. Craig Venter Institute founder Craig Venter: "If someone did this with smallpox or anthrax, I would have grave concerns."
