Video Tip of the Week: GenoCAD for Synthetic Biology

by Mary in OpenHelix

The field of synthetic biology has been simmering for quite a while. It occasionally takes a big leap, such as when Venter’s team published about their work on M. genitalium, and it took a big leap recently with the paper about modeling a lot of the cellular processes in a simple cell that I talked [...]...

Developing New Astro Surgery Tools for NASA Deep Space Missions

by Perikis Livas in Tracing Knowledge

A team of biomedical engineering researchers from Carnegie Mellon University and the University of Louisville are developing surgical tools that could be used for future expeditionary spaceflights to the moon, an asteroid or Mars.

“In deep space, surgical procedures will be severely complicated by absence of gravity, where it becomes difficult to prevent cabin contamination from blood and body fluids,” said James Antaki, a professor of biomedical engineering at CMU.... Read more »

The Logistics of Scientific Growth in the 21st Century

by caseybergman in I wish you'd made me angry earlier

Over the last few months, I’ve noticed an growing number of reports about declining opportunities and increasing pressure for early stage academic researchers (Ph.D. students, post-docs and junior faculty). For example, the Washington Post published an article in early July about trends in the U.S. scientific job market entitled “U.S. pushes for more scientists, but [...]... Read more »

Sensor detects glucose in saliva and tears for diabetes testing

by Perikis Livas in Tracing Knowledge

Researchers have created a new type of biosensor that can detect minute concentrations of glucose in saliva, tears and urine and might be manufactured at low cost because it does not require many processing steps to produce.... Read more »

Video Tip of the Week: G-nome Surfer for table-top genome browsing

by Mary in OpenHelix

The other day a tweet came over my “genome” search column that intrigued me: RT @oshaer: Our paper on a tabletop interface for collaborative exploration of genomic data is finally available online: http://t.co/VQMD67wi Tabletop interface? Wha? Ok–I had to check this out. And, in fact, this group has software that will let you explore eukaryotic [...]... Read more »

How to Build a Neuron: Step 1

by TheCellularScale in The Cellular Scale

There are many reasons to try to build a neuron, but fully building a model neuron is an extensive process with many steps.  Today we will discuss the very first step in the neuron-building process: determining the activity and  shape of the neuron. Biocytin filled cortical neurons (source)To determine the shape of neuron, you have to stain it somehow.  There are several ways to do this, but we will focus on the biocytin filling method. To determine the activity of a neuron, ........ Read more »

What is the collective noun for a group of Systems Biologists?

by Duncan Hull in O'Really?

What happened was, I was looking for a Creatively Commons licensed picture of Pedro Mendes to upload to commons.wikimedia.org. That’s not the footballing Pedro Mendes who played for Rangers, Spurs, Pompey and Porto but the systems biologist Pedro Mendes who plays for Virginia Tech and Manchester. Thankfully, another systems biologist, Michael Hucka kindly pointed to his impressive collection of pictures, taken at various events over the years which include some shots of Pedro.

Studying the Effects of Confinement on Cell Division

by Hector Munoz in Microfluidic Future

On Microfluidic Future I like reviewing advancements in therapeutic or diagnostic devices because I’m really drawn to those areas of research. Every once in a while, however, I take interest in research for the sake for knowledge, like the Root Chip. I recently came across an article from Dino Di Carlo of UCLA that describes a microfluidic device used to study cancer cells. The article, “Increased Asymmetric and Multi-Daughter Cell Division in Mechanically Confined Microenvironments&........ Read more »

Geoengineering: taking control of our planet’s climate?

by Perikis Livas in Tracing Knowledge

Concerns about the likely consequences of continuing climate change have greatly increased interest in geoengineering – whether the Earth’s climate could be deliberately modified to counteract global warming due to anthropogenic greenhouse gas emissions. In November 2010, the Royal Society hosted a Discussion Meeting: ‘Geoengineering: taking control of our planet’s climate’ that critically assessed many of the schemes currently being considered. The meeting also too........ Read more »

“The beetle shows us how”

by Perikis Livas in Tracing Knowledge

Insects are experts when it comes to adhesion on dry surfaces. However, in nature, plants may be covered by water for quite a long period of time, especially after rain. The bionic expert Professor Stanislav Gorb of Kiel University, Germany, and the material scientist Professor Naoe Hosoda of the National Institute for Material Science in Japan, discovered the remarkable ability of the terrestrial leaf beetle to walk underwater. Picking up the beetle’s locomotion mechanism, they designed a........ Read more »

Holistic Design Factors in Space Colonies

by Jason Carr in Wired Cosmos

Assuming that we never achieve FTL travel, generational colony ships may become a necessary method used to traverse great distances. Inherent in the term generational, individuals will live their entire lives on these massive spaceships as will their descendants. In other words, these space ships will be the only home many generations of inhabitants will [...]... Read more »
