When you purchase medicine at the drugstore, you assume that it’s what you think it is and that the active ingredient in the drug is present in the specified concentration. Unfortunately, your assumption might be all wrong. Counterfeit and substandard medicines have become widespread, particularly in low- and middle-income countries with weak regulatory systems. Indeed, according to the World Health Organization (WHO), one out of 10 medicines sold in developing countries should be considered “substandard.” Your drug could even be an outright fake.

“But I live in the United States,” you may say. “The medicines at my pharmacy are regulated by the U.S. Food and Drug Administration, so it must be the genuine article.” Unfortunately, even the United States and other higher-income countries aren’t immune to this scourge. Since 2012, smugglers have been caught selling fake drugs to more than 3,000 doctors, clinics, and hospitals across the United States.

Fires at recycling sorting facilities, ignited by combustible materials in the waste stream, can cause millions of dollars in damage, injuring workers and first responders and contaminating the air.

Detecting the blazes early is key to preventing them from getting out of control.

Mayo Clinic researchers have developed an artificial-intelligence algorithm that can detect weak heart-pump functioning from a single-lead electrocardiogram (ECG) on the Apple Watch. Early results indicate that the ECG is as accurate as a medically ordered treadmill stress test but could be performed anywhere, the researchers say.

The single-lead AI algorithm was adapted from an existing algorithm that works by analyzing ventricular pumping data from a 12-lead ECG already in clinical use under an Emergency Use Authorization from the U.S. Food and Drug Administration (FDA).

If you want to enhance your modeling and design processes for microfluidic organ-on-a-chip devices, tune into this webinar.

You will learn methods for simulating the performance and behavior of microfluidic organ-on-a-chip devices and microphysiological systems in COMSOL Multiphysics. Additionally, you will see how to couple multiple physical effects in your model, including chemical transport, particle tracing, and fluid–structure interaction. You will also learn how to distill simulation output to find key design parameters and obtain a high-level description of system performance and behavior.
