Diabetes affects more than 40 million people in the United States, according to the American Diabetes Association. For many, the chronic condition means a lifetime of pain as worsening circulation leads to nonhealing ulcers in the extremities, especially the legs and feet.

Chronic inflammation, difficulty in forming nutrient-carrying capillaries, and overzealous immune cells that attack healing tissue all combine to make diabetic foot ulcers one of the most difficult wounds to treat...

While sustainable solar energy can potentially meet our global power needs, it has one major flaw. When sunlight disappears, solar panels stop generating electricity. The problem is that while they do an excellent job of converting light into power, they are not so good at storing the energy they collect.

One solution is to use materials known to capture heat and release it later, such as phase change materials (PCMs)...

The Dark Energy Spectroscopic Instrument (DESI) has successfully completed the largest high-resolution 3D map of the universe ever made, a major milestone in understanding the force driving cosmic expansion. The milestone was reached when DESI’s 5,000 fiberoptic sensors captured their final scheduled observations, targeting a region of sky near the Little Dipper.

Many institutions globally are involved in the project, including the University of Portsmouth, University College London and Durham University along with Berkeley Lab and the Science and Technology Facilities Council.

The survey was completed ahead of schedule and has delivered significantly more data than orig...

Successful 3D printer calibration is the fundamental bridge that takes your production quality from “good” to “perfect.” While most enthusiasts focus on temperature, mastering Pressure Advance is the true secret to professional-grade results. This guide serves as a vital technical extension of our 3D Printing Guide Review and complements our deep-dive into Precision 3D Printer Calibration.

What is Pressure Advance in 3D Printing?

Pressure Advance (known as Linear Advance in Marlin firmware) is a predictive technology that manages the internal pressure of the hotend. Because 3D printing filament is slightly elastic, the extruder often pushes too much plastic during deceleration and too little during acceleration. This phenomenon causes bulging corners and uneven surfaces.
