3.6 out of 1,000 children in the US are diagnosed with cerebral palsy. Their symptoms can include abnormal gait patterns such as crouch gait, characterized by excessive flexion of the hips, knees, or ankles. A pilot study demonstrates a robotic training method that improves posture and walking in children with crouch gait by enhancing their muscle strength and coordination.

Gamma-ray bursts are among the most energetic and explosive events in the universe. They are also short-lived, lasting from a few milliseconds to about a minute. This has made it tough for astronomers to observe a gamma-ray burst in detail. Using a wide array of ground- and space-based telescope observations, astronomers constructed one of the most detailed descriptions of a gamma-ray burst to date.
