A model for development: biologists create first predictive computational model of gene networks
(Phys.org)—As an animal develops from an embryo, its cells take diverse paths, eventually forming different body parts—muscles, bones, heart. In order for each cell to know what to do during development, ...
How to control complex networks
At first glance, a diagram of the complex network of genes that regulate cellular metabolism might seem hopelessly complex, and efforts to control such a system futile.
A new type of genetic variation could strengthen natural selection
(PhysOrg.com) -- The unexpected discovery of a new type of genetic variation suggests that natural selection - the force that drives evolution - is both more powerful and more complex than scientists have ...
First mammalian 'cell phone'
(Phys.org)—Researchers from ETH Zurich have quite literally created a "cell phone": they have reprogrammed mammalian cells in such a way that they can "phone" each other via chemical signals.
Bioengineers recreate natural complex gene regulation
By reproducing in the laboratory the complex interactions that cause human genes to turn on inside cells, Duke University bioengineers have created a system they believe can benefit gene therapy research ...
Discovery offers bio-solution to severe canola crop losses
A genetic discovery by a University of Calgary-led international research team offers a solution to a long-standing "green seed problem" that causes millions of dollars annually in canola crop losses.
Novel approach to gene regulation can activate multiple genes simultaneously
By creating a powerful new gene regulation system called CRISPR-on, Whitehead Institute researchers now have the ability to increase the expression of multiple genes simultaneously and precisely manipulate each gene's expression ...
To germinate, or not to germinate, that is the question
Scientists at the University of York have uncovered new insights into the way seeds use gene networks to control when they germinate in response to environmental signals.
Computer Based on Insights From The Brain Moves Closer to Reality
(PhysOrg.com) -- Today at SC 09, the supercomputing conference, IBM announced significant progress toward creating a computer system that simulates and emulates the brain's abilities for sensation, perception, ...
Researchers divide enzyme to conquer genetic puzzle
Rice University researchers have found a way to divide and modify enzymes to create what amounts to a genetic logic gate.
Minus environment, patterns still emerge: Computational study tracks E. coli cells' regulatory mechanisms
Environment is not the only factor in shaping regulatory patterns—and it might not even be the primary factor, according to a new Rice University study that looks at how cells' protein networks relate to ...
Wiggling worms make waves in gene pool
The idea that worms can be seen as waveforms allowed scientists at Rice University to find new links in gene networks that control movement.
Solving stem cell mysteries
The ability of embryonic stem cells to differentiate into different types of cells with different functions is regulated and maintained by a complex series of chemical interactions, which are not well understood. Learning ...
Molecular algebra in mammalian cells
(Phys.org) -- Mammalian cells can now do what an electronic calculator can: perform logical calculations. Swiss researchers have equipped cells with a complex genetic network that can do more than just one ...
