A study in Science tested one AI model on 146 kinds of findings in abdominal CT scans. Radiologists who used it caught about 10 more real findings out of every 100, with a small rise in false alarms. Here is what the test showed, and what it did not.
Saleh Ramezani, PhDOctober 2, 2026In a new Lancet lecture, a cancer researcher argues that screening should match each person's risk. I agree, as long as it also means doing less for people at low risk.
Saleh Ramezani, PhDSeptember 25, 2026A 2025 consensus guideline asks for medical AI to be monitored for its whole working life. Radiation therapy machines have lived by that rule for decades.
Saleh Ramezani, PhDSeptember 12, 2026An AI system wrote a paper that cleared reviewers at an ICLR workshop. It is a real milestone, and an honest stress test of peer review itself.
Saleh Ramezani, PhDAugust 7, 2026In June 2026, bioRxiv's parent openRxiv began testing an interactive way to read preprints. It is an experiment, and I think it asks the right question.
Saleh Ramezani, PhDJuly 2, 2026Doctors in Philadelphia designed a gene-editing drug for a single infant in about six months. The early results are real, but they come from one child and a few weeks of follow-up.
Saleh Ramezani, PhDJune 18, 2026A 2023 survey put numbers on the extra hours, rejections and skipped conferences that come with doing science in a second language. Journals and conferences can shrink that cost.
Saleh Ramezani, PhDMay 22, 2026A January 2026 Nature study links AI use to bigger scientific careers and a narrower spread of research topics. Both can be true at once, and that is the problem.
Saleh Ramezani, PhDApril 27, 2026A Swedish screening trial randomized more than 100,000 women to test AI in real mammography. That, not another benchmark score, is what earns trust.
Saleh Ramezani, PhDMarch 6, 2026In a 2025 experiment, Turkish high school students did far better on math practice with GPT-4. Those given a plain chatbot then did worse on their own. Tutor design made the difference.
Saleh Ramezani, PhDFebruary 26, 2026A 2025 study reported tiny bits of plastic in human brains, with more in people who had dementia. The finding is real news, but it is not proof of harm.
Saleh Ramezani, PhDFebruary 9, 2026A small MIT study found that people who let ChatGPT write their essays remembered little of them. That is a real cost for learning, and it is not brain damage.
