Respiratory diseases like measles, flu, tuberculosis, and COVID-19 are all transmitted by droplets. Some are tiny and airborne, capable of traveling long distances. Other drops are larger and only capable Keep reading

EpiPen in Action
Researchers are hard at work developing needle-free alternatives to injection, but devices like the EpiPen — used in anaphylactic emergencies for food and insect allergies — aren’t going anywhere yet. Keep reading
Gathering Safely
One effect of the COVID-19 pandemic is a renewed interest in the physics of disease transmission and what measures can protect us from airborne respiratory illnesses. This recent study looks Keep reading
Disease and Placental Flows
The human placenta functions as a life-support system for a growing fetus. Despite its frisbee-like appearance, the organ is packed with nearly 10 square meters of blood vessels. On the Keep reading
Walking in the Wake of a Cylinder
A cylinder in a flow produces a series of alternating vortices known as a von Karman vortex street. Changing the flow speed and rotating the cylinder both allow researchers to Keep reading
Breaking Clots With Sound
Clots that block blood flow away from the brain are one of the most common causes of strokes for younger people. If caught early, anticoagulants can sometimes resolve the issue, Keep reading
Toilet Plumes
Toilet flushes are gross. We’ve seen it before, though not in the same detail as this study. Here, researchers illuminate the spray from the flush of a typical commercial toilet, Keep reading
Sound Makes Stickier Bandages
Keeping wounds safe and clean is hard when bandages are so prone to coming off. A team of researchers may have found a solution, though, using ultrasound to enhance adhesion. Keep reading
Inside a Coronavirus Aerosol
This is a glimpse inside a tiny aerosol droplet with a single SARS-CoV-2 coronavirus inside it. The numerical simulation required a team of 50 scientists, 1.3 billion atoms, and the Keep reading
Better Inhalers Through CFD
As levels of air pollution rise, so does the incidence of pulmonary diseases like asthma. Treatments for these diseases largely rely on inhalers containing drug particles that need to be Keep reading
