By simulating 25,000 generations of evolution within computers, Cornell University engineering and robotics researchers have discovered why biological networks tend to be organized as modules - a finding that will lead to a deeper understanding of the evolution of complexity. (Proceedings of the...
In Alzheimer's disease, brain neurons become clogged with tangled proteins. Scientists suspect these tangles arise partly due to malfunctions in a little-known regulatory system within cells. Now, researchers have dramatically increased what they know about this particular regulatory system in...
Ecologist Eric Berlow doesn't feel overwhelmed when faced with complex systems. He knows that more information can lead to a better, simpler solution. Illustrating the tips and tricks for breaking down big issues, he distills an overwhelming infographic on U.S. strategy in Afghanistan to a few...
I'm having a lot of trouble with this question for my biology class.
We were studying cells, so the trend should;d be described on a cellular level.
Please help if you can. :)
The more complex a plant or animal, the more difficulty it should have adapting to changes in the environment. That's been a maxim of evolutionary theory since biologist Ronald Fisher put forth the idea in 1930. But if that tenet is true, how do you explain all the well-adapted, complex...
Sociodemographic variables also do not seem to affect comprehension. Although informed consent is an ethical cornerstone in research with humans, some studies suggests that volunteers often do not understand key aspects of the research in which they participate. Recent efforts have been made to...
Researchers at the University of Toronto have discovered a fundamentally new view of how living cells use a limited number of genes to generate enormously complex organs such as the brain. In a paper published on May 6 in the journal Nature entitled "Deciphering the Splicing Code," a research...
