Penn State Abington student Cezary Krysztofiak used a CNC machine to fabricate an aluminum structure for CubeSat within the required tolerance of < 0.1 mm. A CNC, or computer numerical control machine, is a high-precision tool that is computer-controlled and makes repeated, accurate movements.
To test how the prototype would perform at high altitudes, Penn State Abington student Lingqi Li used the cooling baths method to model the temperature of the stratosphere at minus 56 degrees Celsius (approximately minus 69 degrees Fahrenheit). After several versions of these tests, the students could identify which components would satisfy the thermal requirements of flight tests.
Researchers from the College of Information Sciences and Technology found that creating computer-supported collaborative learning environments could help online learners build community and increase the likelihood that they would remain in their academic program.

Nonmedical opioid users were more likely to say they began abusing opioids after friends and family members offered them the drugs, according to researchers. About 56 percent of the interviewees said they began using the painkillers recreationally first.
