As Benjamin Franklin once joked, death and taxes are universal. Scale-free networks may not be, at least according to a new study from 欧美口爆视频 Boulder. The research challenges a popular two-decade-old theory that networks of all kinds, from Facebook and Twitter to the interactions of genes in yeast cells, follow...

Tobacco and alcohol use are leading causes of mortality that influence risk for many complex diseases and disorders 1 . They are heritable 2,3 and etiologically related 4,5 behaviors that have been resistant to gene discovery efforts 6-11 . In sample sizes up to 1.2鈥塵illion individuals, we discovered 566 genetic...

Researchers at 欧美口爆视频 Boulder have developed virtual clinical trials for an artificial pancreas that could significantly improve treatments for those with Type 1 diabetes by tailoring medical devices and speeding up trials. The work was done through a four-year, $600,000 award from the National Science Foundation and was headed at...

A study of the bacterial slime in showerheads across the world has found US cities are hotspots for potentially harmful bacteria. Researchers found that mycobacteria is the most common bacteria in showerheads. They found it is far more prevalent in the United States than in Europe, thrives more in municipal...

As humans evolved and expanded, so too did barn swallows, new research from 欧美口爆视频 Boulder suggests The evolution of barn swallows, a bird ubiquitous to bridges and sheds around the world, might be even more closely tied to humans than previously thought, according to new study from the University of...

In this paper, we provide an approach to data-driven control for artificial pancreas systems by learning neural network models of human insulin-glucose physiology from available patient data and using a mixed integer optimization approach to control blood glucose levels in real-time using the inferred models. First, our approach learns neural...

Groups of interacting active particles, insects, or humans can form clusters that hinder the goals of the collective; therefore, development of robust strategies for control of such clogs is essential, particularly in confined environments. Our biological and robophysical excavation experiments, supported by computational and theoretical models, reveal that digging performance...

Mating activities change within a season in many animal and plant populations. In plants, selection towards early flowering is commonly observed. Pollinator鈥恗ediated selection is hypothesized to be a pervasive evolutionary force acting directionally on flowering time. However, pollinator鈥恗ediated mechanisms have rarely been tested in realistic field conditions, especially in perennial...

Recent biological research has sought to understand how biochemical signaling pathways, such as the mitogen-activated protein kinase (MAPK) family, influence the migration of a population of cells during wound healing. Fisher's equation has been used extensively to model experimental wound healing assays due to its simple nature and known traveling...
