South Korea's flag carrier Korean Air will begin weighing passengers and their carry-on luggage at Gimpo and Incheon airports. The Ministry of Land, Infrastructure and Transportation has required the checks to collect actual passenger weights for aircraft weight-and-balance calculations. Airline officials say measuring passengers helps crews calculate load distribution, takeoff performance, and fuel needs more accurately than relying on assumed average weights. Officials emphasize it is about technical calculations, not personal data collection.

In 2009 the Large Hadron Collider (LHC), a giant particle accelerator near Geneva run by CERN, was preparing to restart after upgrades. Scientists said the machine would smash protons together at very high energies to study fundamental particles and forces, potentially revealing phenomena such as the Higgs boson or signs of new physics. However, some members of the public expressed fear that the machine could produce catastrophic effects, including miniature black holes or other unknown dangers.

Google plans to release a redesigned Fitbit app this fall that reorganizes the interface into three main tabs: "Today," "Coach," and "You." The refreshed app will display daily health statistics, offer motivational and coaching content, and present goal overviews and trends. Google says the update will improve how fitness data is presented and protected, and it appears visually aligned with leaked looks of the upcoming Pixel Watch 2 and possibly the Pixel 8 phones.

Scientists presented results from the OPERA study showing artificial intelligence can analyze heart ultrasound scans in about one minute, compared with roughly 30 minutes for trained human experts. The project, led by the University of Glasgow in partnership with AstraZeneca and NHS trusts including Greater Glasgow & Clyde and the Golden Jubilee, demonstrated the AI’s ability to interpret echocardiograms quickly and consistently during a presentation at the European Society of Cardiology conference in Amsterdam.
