3D Biology Game: An Idea Worth Funding

 :: Posted by American Biotechnologist on 12-06-2012

This past summer a group of artists and indie game developers in the Seattle area attempted to develop a super-cool video game that allowed player to explore the inside of a cell as if they were actually inside the 3D structure. Unfortunately, the team was unsuccessful in meeting its funding goal, however, they left a strong impresson on me and I believe that they have a product which can seriously help revitalize the biology classroom.

Checkut the video from Kinect Biology and give us your feedback. Do you think that there idea is worth funding?

Precision Motion Tracking – Thousands of Cells at a Time

 :: Posted by American Biotechnologist on 09-18-2012

Researchers have developed a new way to observe and track large numbers of rapidly moving objects under a microscope, capturing precise motion paths in three dimensions.

Over the course of the study–reported online Sept. 17, 2012, in the Proceedings of the National Academy of Sciences–researchers followed an unprecedented 24,000 rapidly moving cells over wide fields of view and through large sample volumes, recording each cell’s path for as long as 20 seconds.

“We can very precisely track the motion of small things, more than a thousand of them at the same time, in parallel,” says research lead and National Science Foundation CAREER awardee Aydogan Ozcan. an electrical engineering and bioengineering professor at UCLA. “We were able to achieve sub-micron accuracy over a large volume, allowing us to understand, statistically, how thousands of objects move in different ways.”

Google earth for cell biologist

 :: Posted by American Biotechnologist on 08-06-2012

Just as users of Google Earth can zoom in from space to a view of their own backyard, researchers can now navigate biological tissues from a whole embryo down to its subcellular structures thanks to recent advances in electron microscopy and image processing, as described in The Journal of Cell Biology (JCB). An upgrade to the JCB DataViewer (http://jcb-dataviewer.rupress.org), JCB’s browser-based image presentation tool, now also makes these data publicly accessible for exploration and discovery.

A Simple Way to Study Cells

 :: Posted by American Biotechnologist on 02-08-2012

Remember MacGyver? He could do almost anything with a piece of scotch tape and a paper clip. The following story reminds me very much of McGyver and how much can be accomplished with a little imagination.

National Institute of Standards and Technology (NIST) research engineer Javier Atencia has a reputation for creating novel microfluidic devices out of ordinary, inexpensive components. This time, he has combined a glass slide, plastic sheets and double-sided tape into a “diffusion-based gradient generator”—a tool to rapidly assess how changing concentrations of specific chemicals affect living cells.

New technique for watching proteins in action in intact cells

 :: Posted by American Biotechnologist on 11-01-2011

Proteins are literally the movers and the shakers of the intracellular world. If DNA is the film director, then they are the actors. And much can be learned about cell function – and dysfunction – by watching proteins on the move.

Until now, scientists have only been able to see this process indirectly. Now researchers at Vanderbilt University in Nashville, Tenn., have come up with a promising new technique that uses a scanning transmission electron microscope (STEM) to view proteins tagged with gold nanoparticles in whole, intact cells.
