McFlurries Aid in the Fight for the Right to Repair

McDonald’s is notorious for their broken McFlurry machines, though the reason behind their malfunctioning is surprising. The manufacturers of these machines have forbidden McDonald’s from outsourcing repairs, but purposely make their machines fragile because they make millions off of fixing them. This highlights a greater issue in the engineering community: the fight for the right to repair. Consumers should not be forced to turn to original manufacturers to repair their products. Due to its high-profile nature, McFlurry machines may finally push Congress to pass the bill that would secure this right once and for all.

Engineering Cleats Just for Women 

The FIFA Women’s World Cup kicked off earlier this month, but many household names are missing from the pitch. Many players have been ruled out due to serious knee injuries. Experts say ACL injuries may plague female soccer players frequently due to ineffective footwear. Historically, women’s soccer cleats have been designed for men and then re-dressed to appeal to women. Recently, footwear engineers have come together to remedy this issue; they have finally begun designing cleats for female athletes.

3D Printing: Revolutionizing the Making of Prosthetics

3D printing has made significant advancements in the medical field, particularly in the production of prostheses. The first 3D-printed prosthetic was developed in 2011 for a family that could not afford a prosthetic. Though the high cost of conventional prosthetics remains a significant barrier for many individuals, innovations in 3D printing offer more affordable alternatives. A functional prosthetic has recently been created with a price tag of just over $25, proving that prosthetics can become more accessible.

Study Announces Use of CAR T-Cell Therapy Against Solid Tumors

CAR T-cell therapy, a revolutionary treatment for blood cancers, genetically modifies T-cells using CRISPR to replace their receptors with specialized ones called CARs. These CAR T-cells target antigens on cancerous blood cells, triggering an immune response that enables the patient’s body to destroy cancer cells. Additionally, CRISPR is used to deactivate genes that hinder the therapy’s efficacy. However, CAR T-cell therapy has struggled to target solid tumors due to their heterogeneity. Recent research from MIT’s Koch Institute introduces a promising solution using amphile fluorescein isothiocyanate tagging (amph-FITC). By injecting tumors with amph-FITC tags and treating them with FITC-specific CAR T-cells, researchers achieved successful tagging and destruction of cancerous cells while minimizing impact on healthy tissue. This breakthrough, although not yet tested on humans, holds potential to effectively treat and cure various cancers if approved for clinical applications.
