Clinging to Life:

Millions of platelets cling to a damaged arterial wall in this multi-scale visualization of a blood clot. The yellow particles are activated, clot-forming platelets whereas the red ones are nonactivated, free-flowing platelets.....[ More ]

Follow the Leader:

Activated cells (blue) adhere to the walls of a blood vessel, stopping non-active cells (red) and leading to a stoppage of blood flow. The clotting process can be lifesaving in the case of injury. It is triggered when normally flowing blood is exposed to collagen and other substances present in a ruptured vessel.....[ More ]

First of Many:

A single red blood cell adheres to an arterial wall in this visualization of a ruptured aneurysm. The colored lines represent the varying speed of blood flow around the cell.....[ More ]

The Big Picture:

The four main arteries in the brain's circulatory system are pictured on the left (the right and left carotid, basilar and cerebral). At the top right is the location of an aneurysm researchers modeled to show platelet and blood cell aggregation forming a blood clot.....[ More ]

Forest and the Trees:

Blood flowing through the major brain arteries and an aneurysm is depicted on the left. The zoomed-in image (right) shows microscopic platelets and blood cells aggregating at the site of a ruptured aneurysm.....[ More ]

An Unprecedented Visualization:

Multi-scale modeling helps scientists forecast weather, model tornado formation and understand complex biological processes that have important features at multiple scales. Researchers at Brown University and Argonne National Laboratory used more than 300,000 computer processors to create this parallel computing model that simulates a blood clot forming in a ruptured aneurysm.....[ More ]
