 | A new paper from researchers at Yale University and the National Institute of Standards and Technology describes a highly simplified model cell that not only sheds light on the way certain real cells generate electric voltages, but also acts as a tiny battery that could offer a practical alternative to conventional solid-state energy-generating devices. ...> Full Article |
New research reveals that regulatory differences between mother and daughter cells during cell division are directly linked to how they prepare for their next split.

All of life is founded on the interactions of millions of proteins. These are the building blocks for cells and form the molecular mechanisms of life. The problem is that proteins are extremely difficult to study, particularly because there are so many of them and they appear in all sizes and weights. Now, Kris Gevaert from VIB/Ghent University and colleagues from the universities of Freiburg and Bochum have achieved a breakthrough in protein research.

Stripe-micropatterned surfaces have recently been a unique tool to study cell orientation. This paper employs the photolithographic transfer technique to generate cell-adhesive gold microstripes on cell-adhesion-resistant polyethylene glycol hydrogels. 3T3 fibroblasts were cultured on Au-microstripe surfaces to observe cell adhesion and orientation. Five statistical parameters were defined and used to describe cell orientation on micropatterns. The combination of the five statistical parameters represented well the cell orientation behaviors semi-quantitatively.

 | As scientists work toward making genetically altered bacteria create living "circuits" to produce a myriad of useful proteins and chemicals, they have logically assumed that the single-celled organisms would always respond to an external command in the same way. ...> Full Article |
When it comes to the two basic types of cells, prokaryotes and eukaryotes, compartmentalization is everything. Prokaryotes are evolutionarily ancient cells that only have a membrane surrounding their outer boundary, while the more complex eukaryotes have an outer membrane and membrane bound compartments within the cell. Perhaps most notable is the double layered membrane that surrounds the nucleus, the cellular compartment which houses the cell's genetic material.
