Home Office travel records used in a trial of a controversial anti-fraud crackdown that under which thousands of parents lost their child benefit were so flawed that almost half of the families initially flagged as having emigrated were still living in the UK, it has emerged.

Anshul Kundaje sums up his frustration with the use of artificial intelligence in science in three words: "bad benchmarks propagate". He expresses concern about questionable claims made by researchers about AI models, which take months to verify and often turn out to be false due to poorly defined benchmarks. This problem creates misinformation and wrong predictions, as flawed benchmarks are misused by enthusiastic users. The lack of reliable benchmarks threatens to undermine AI's potential to accelerate scientific progress rather than enhance it.
