The lumbar spine includes the five vertebrae in your lower back numbered L1 to L5. These bones help provide mobility and stability to your back and spinal column and are an attachment point for ...

(Credit: NASA) Within the Earth-Sun system, there are five Lagrange points (L1 – L5), of which L2 is currently the home of the James Webb Space Telescope (JWST) and was the home to previous ...

The team solved a key puzzle—why solar wind measurements differ between L5 and Earth-orbiting L1 observatories. They traced the variations to three critical factors—the combined effect of smaller ...

Scientists from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences, in collaboration with ...

Each lumbar disc (L1/2–L5/S1) was examined for the presence and degree of disc degeneration. Discs were graded as normal, or degenerate on a scale of 1 (mildly degenerated) to 3 (severely degenerated) ...
