Computer simulation helps explain how plants grow
The petals of every flower and the leaves sprouting from every plant stalk have characteristic arrangements, a phenomenon called phyllotaxis. For two centuries, botanists have puzzled over the force...

Simulations illuminate the inner workings of blood at multiple levels
Understanding blood flow and coagulation is crucial to treating blood disorders such as hemophilia and thrombosis, and to dealing with diseases such as AIDS, malaria, and diabetes that have...

2-D simulation shows angiogenesis as it happens
Microscopic capillaries grow on demand, snaking toward hungry cells needing their blood supply. Understanding how to control this process could help scientists promote wound healing or halt cancer in...

Molecular dynamics simulations spot alternative drug target
A blindside attack on HIV-1 protease might just combat drug-resistant strains of HIV, according to simulations run by researchers at the University of California, San Diego. When the simulations shut...

It's an exhilarating time for genome-wide association studies
For the past few months it seemed you couldn’t open a journal without reading results of a new genome-wide association study. The results kept pouring in: four studies in April showing seven...

Computing airflow dynamics
We can’t see them, but tiny particles—dust, pollen, microbes, and the like—swirl around us in complicated, turbulent pathways. New numerical simulations suggest that, at least in...
