K-Mistry Typeface By Ranmalee Jayaratne

I wanted to take a moment to thank Ranmalee for her wonderful concept and execution of the K-mistry type face in the banner for this site. 

It is refreshing to see young designers take on the difficult challenge of presenting the life sciences and other technical  sectors as appealing. Although it does not come as a surprise that Ranmalee, a 21 year old from Sri Lanka who decided to switch her studies from advanced mathematics to design, found such a wonderful way to balance her output.

If you’re like me, and look forward to what Ms. Jayaratne will create next, be sure to keep an eye on her Behance page.

Industry & Academia, part 1

The biotech, pharmaceutical and life sciences industry poses an interesting conundrum. How do we industrialize a profession of problem solving? From experience, I can say some have done it well, while others have treated the life sciences like a traditional industry. Much of the novel molecules which lead to profitable drugs often have their beginnings in academic research. Here a molecule or procedure showing promise is quickly gobbled up by an industrial giant, with very fair compensations of course. In academic research labs problem solving can bee seen to take a two-pronged approach. The first is collecting and presenting data which will ensure future and continued monetary funding. The second and more important aspect, is everyone in the lab understanding their individual projects from the bottom-up; to understand the basic concepts of nature which are guiding the protocols of an experiment. And it is at this where industry shows it’s largest short-coming. Departmentalizing work within a single project causes individuals to differ responsibility of the overall project success. This creates a lack of vigilance, people let flaws in experimental design slip by, those whose experience can best help troubleshoot aren’t even asked. The biotech industry isn’t young and fledgling anymore and allowing it to be run through the lens of a traditional business will do little to assure future success.

A Breakdown of a Groundbreaking Article

Finding treatments for Parkinson’s disease helps more than just those afflicted with the illness. The mere act of studying the disorder and looking for a cure has increased mans understanding of the physiological structure of the brain and it’s relation to movement of the body.

This article by Kim et al, was published in Nature, vol 418. These researchers are interested in deriving dopamine neurons from embryonic stem cells (ES cells);   Parkinson’s disease is caused by the loss of neurons that produce dopamine.

Showing ES cells with Nurr1 has positive results for multiple markers of dopamine production

To quantitatively measure how much dopamine these ES cells could produce the researchers stained for tyrosine hydroxylase (TH), which  catalyzes the conversion of L-tyrosine to dihydroxyphenylalanine (DOPA), the precursor for dopamine. Nuclear receptor related-1 (Nurr1) is a transcription factor that has a role in the differentiation of midbrain precursors into dopamine neurons.

In the study ES cell lines expressing Nurr1 are compared to native dopaminergic neurons and WT ES cells. Nurr1 ES cells outperform both comparative cell lines in TH stains, showing greater dopamine production.

Once the authors have demonstrated that their ES cell line with Nurr1 can produce dopamine just as well native dopamine producing neurons, they move on to graft the newly created cell lines to show that they don’t lose their capabilities within an animal model. At the very base, this study demonstrates the ability of embryonic stem cells to be turned into neurons capable of producing specific compounds, just as well native neurons.

Some thoughts on the mind

What do we currently know about the cellular structure of the brain? How does it affect our concept of reality? A quick & basic summary:3 views of the neuron

The cells of the brain, neurons, have a structure very different from the rest of the body.

At the center of the neuron is the soma, the core. From here branch-like structures called dendrites emerge. The axon, is a single stem which can extend from the soma to very distant spaces, ranging from inches to several feet.

Every thought, feeling, perception, or memory causes an electrical potential to be generated at the soma, passed down the axon and then transferred to other neur ons through dendrites. There are millions of connections between neurons, turning the whole brain into one large network.

This is the stage on which our reality unfolds, everything we learn, everything we feel, all movements and all thoughts occurs through the medium of our neural network.
