On 29 September, Northwestern University neuroscientists reported that response speed is faster on an exhalation than an inhalation by an average of 41 milliseconds, a result published in the journal iScience. The same day, CBC News covered a Lancet Oncology study estimating that infections caused 2.3 million new cancer cases in 2024.
A University of Texas at Austin team fitted 82 young adults with a wrist-worn tracker and found that physical activity lengthened REM latency. A separate three-month study of 800 young adults found "basically zero" correlation between a Garmin watch's stress score and what users said they felt.
US and Canadian authorities have recalled the INMO Air3 AR glasses after the left temple was found to overheat, with 1,643 units sold in the US and 120 in Canada.
China now hosts more elite AI researchers than the United States, according to a Carnegie China study published on 28 September, while a US insurance group claims hospitals' use of AI added $942 million to healthcare spending over two years.
US and Canadian regulators announced a recall of the INMO Air3 AR glasses on 27 September, citing an overheating left temple that can cause serious burns, with 1,643 units sold in the US and 120 in Canada.
A University of Texas at Austin study tracked 82 young adults with a wrist-worn activity tracker and a smartphone app over several months. Physical activity lengthened REM latency, the time it takes to enter REM sleep.
Discriminative medical AI models can be tricked into confirming whether a specific patient's records were part of their training data, German researchers report in a Nature paper published on 24 June. On individual patients, the attack succeeded almost every time.
Two separate studies published in 2026 show that medical diagnostic AIs can be tricked into revealing which patients' data trained them, and that leading language models fail at early differential diagnosis in more than 8 out of 10 cases.
The US Consumer Product Safety Commission ordered a recall of the INMO Air3 AR glasses on 27 September, saying the left temple can overheat during extended use and cause severe burns.
A journal calling itself the Journal of Digital Health Implementation published a paper listing Eric Topol and five other researchers as authors. Most of them had never seen it, and the site was gone within hours.
Two of the most cited medical AI results of the past year point in opposite directions: Microsoft's MAI-DxO hit 85.5% accuracy on 304 complex NEJM cases against 20% for 21 physicians, while a JAMA Network Open study found leading models fail early differential diagnosis in more than 8 out of 10 cases. Regulators now have to write rules for both numbers at once.
Oracle's Cerner unit, now Oracle Health, is back at the centre of divestiture speculation after a round of cuts at the health division, while researchers keep publishing studies on what wearable data can and cannot predict.
A University of Texas at Austin study tracked 82 young adults with a wrist-worn Fitbit for months instead of one night in a clinic, and found physical activity lengthened REM latency. The bigger shift, researchers say, is that consumer wearables are now being used to study sleep and health outside laboratories at all.
Wearables are producing sleep and stress data at a scale labs never could. Two 2024 studies and one 2025 critique show the evidence is only as good as the hardware and the interpretation behind it.
A University of Texas at Austin study published in Nature Scientific Reports used wrist-worn trackers to follow 82 young adults for weeks and months. Physical activity lengthened REM latency. Consumer wearables are moving from fitness gimmicks to research instruments.
A University of Texas at Austin study tracked 82 young adults with a wrist-worn Fitbit for months at home rather than one night in a lab, and found that physical activity lengthened REM latency, the time it takes to enter REM sleep.
Researchers at the University of Texas at Austin tracked sleep and activity in 82 young adults for months, not one night, using consumer wearables. The results, published in Nature Scientific Reports, show that physical activity lengthened REM latency, the time it takes to reach REM sleep.
