stably

The electrolyzer stack performed consistently and stably for over 125 hours -- a testament to its robustness, Jiao said.

Overall, the volunteers were able to stand stably with much less effort when assisted by the robot, compared to when they tried to stand alone while wearing the bulky suit.

They are also limited by the power of their lasers, which they spent years carefully tuning to work stably at the desired wavelengths.

The researchers also found that fragrant screw pines' male and female flowers produced heat at night stably, making them the first such species in the family Pandanaceae.

The Astrobotic company behind the project says its Peregrine spacecraft has experienced an "anomaly" that has stopped it from pointing its solar panels stably at the Sun.
