I mentioned a link in previous post that crashed my browser. I was referencing an interview between Exxon CEO and Charlie Rose wherein Exxon spoke about their research to genetically engineer algae--the oldest living organism on the planet. Rather than simply use algae as it now exists after how many thousands of years of evolution, they wanted to bio-engineer it so they could profitably make fuel from it.
I am one of those people who is reluctant to believe that we can do such meddling with 'Mother Nature' safely. I have seen the damage of genetic pollution from promising biotech companies who mess with the gene pool for plants and claim they are the owners of plant species by virtue of their scientific experiments. There is something inherently disrespectful about the presumption that a young understanding of genetic information is somehow superior to the wisdom of natural life, natural species that have adapted slowly and developed in response to environment. We have history of introducing plants and animals across the planet and creating disruptive or invasive species that do not have natural barriers to their unchecked or rampant growth.
Anyway, I clearly can be viewed as a Luddite or someone against technology but I do understand the hope and fervor of men of science who want to make their mark and leave a legacy and to do things in a big way. I am encouraged by news of individual tinkerers and scientists who devise carburetors that can get 60+ miles per gallon of gas or people who develop cars that run on water or other discoveries that reflect a sensibility and respect for the planet and other life forms. What I hope we guard against as we delve into genetic product development is the propensity to allow entities of scale and economic might to dictate the commercial integration of products that do not serve the highest good but are flawed and allowed to proceed because of the commercial investments made and the objectives of earning profit or gaining market share.

Genetic Engineering
I watched "Life at the Speed of Light" interview with Microbiologist J. Craig Venter after viewing the assigned video "The Frost Interview." Both provide valuable perspectives that when analyzed are very useful to the discussion of bioethics and decisions that are determining the future of life on this planet. The "Life at Speed of--" interview was longer but very informative.
In the Frost Interview, we learn that he was a surfer who went to Vietnam as a corpsman that instilled his desire to study medicine and become a third world doctor. He then started off in a new direction and found his passion in life--biochemistry and research! He later was working at National Institutes of Health (NIH) as a scientist who grew dissatisfied with lack of funding for some research and left to do the work that could and was funded by private sources. Although Frost tries to paint him as an egoist or at least reference allegations of this, I found myself admiring Venter for having the tenacity and self-confidence needed to focus on the achievements he has made, no doubt the critical remarks are at least tinged with professional jealousy and seem to be insignificant to consider when examining the larger magnitude of his work.
He did state that he does not believe in God, which could be an obvious conclusion for a corpsman in Vietnam at age 21. Still it is a daring statement that engenders disdain or worse among a good segment of the American population. Still, if you can remain neutral on that and just consider the nature of his career and the statements he makes, he is revealing through these interviews that he is orchestrating research and admits to being an adrenaline addict. He learned in Vietnam that life is short and is driven by speed and admits that we have a limited amount of time to accomplish things. He says it would be better if science went a whole lot faster and we should have 10 times the pace of discovery that we do.
Novartis is a company that makes vaccines, but has long found flu vaccine unprofitable as it takes at least six months if not a whole year to create them using the egg technology system in place for decades. They are working with Venter to create synthetic vaccine, made entirely from digital code that translates DNA; his work on the Human Genome project was foundation for his understanding that DNA and digital code can be interchangeable and that we have been digitizing biology since 1977. He told story of Chinese virus called H7N9 that he created a vaccine for it in just 10-11 hours! He related that Mexican government didn't want it public that Mexico City was source of a new virus and US government didn't want actual samples of it entering the country. Now they can send digital code of virus instead.
He refers to Asimov who was a biologist before he was a science fiction writer. Venter himself seems to have keen visions and considers that the burgeoning population growth requires that science breakthroughs such as he and his groups are making are needed. He claims that we are evolving socially 1000 times faster than we are evolving biologically and is concerned about the destruction of the environment taking place and says that population pressures will continue unless we devise solutions.
He says people do not credit Monsanto with creating solutions such as Golden Rice in Africa to keep people from starving. Here I differ with his analysis and support for GMO as benign science. I have to respect him for creating a very secure life for himself and a fascinating career and he is well-spoken. He would be an interesting person to invite to a dinner party!

DESIGNER BABIES
http://www.foxnews.com/on-air/special-report-bret-baier/2014/02/27/all-star-panel-debate-over-designer-babies-heats
George Will and other panelists weigh in on the gap or lag time between bioethics and laws with the frontiers of genetic science that have been introduced virtually without such beneficial discussions as a society. Designer babies refers to the idea that parents will soon have the ability to choose not only the sex of their child, but to preselect for intellectual or athletic aptitude as well as desired physical features such as height, or whatever vanity is projected and available for child shoppers using a menu from businesses offering not just genetic counseling but genetic modifications that could involved the mitochondria of a "third parent" with all that entails.
In fact, the debate about surrogate mothers has not kept it from taking place, and the "fertility clinics' around the globe collect DNA and sperm and created the infamous "Octo-Mom' mother of an octet (eight babies) whose vanity and need for attention outweighed the very practical considerations of raising eight babies on top of her pre-existing family as a single mother.
The examples of commercial application of science-engineered discoveries that have not been vetted by society in terms of discussion of the ethical dimensions of the applications and the legal framework to keep up with such rapid and unfamiliar and some might say radical changes have history of having a lengthy gap of more than 10 years.
Given that in my lifetime we have traveled from surrogate moms to the cloning of Dolly the sheep, to the commercial introduction of cloned pigs to the US pork market for humans is evidence that the companies will take the risks and not wait for the laws to tell them if and how they can proceed. Maybe other countries do things differently and decide what research or developments can be introduced, but here in America, money -private money-funds research that develops discoveries that then goes to market and if there is any oversight by civic leaders and the legal system, it happens decades afterwards.
We have cell phone technology that is ubiquitous well before the studies were even contemplated to determine the physical risks of the EM radiation. And then, when such questions and research threaten to undermine profits, companies handily hire teams of PR people to refute the validity of the findings and keep innocent consumers in the dark as long as possible. We can expect this behavior of commercial interests when we consider any and all future genetic or biotech "advancements" that are essentially brought to market via justifications to correct problems but generally create a dozen problems that did not exist before.

Genome # 11
- ANON2; BULN2
- Summary
- The protein encoded by this gene is a member of the nerve growth factor family. It is induced by cortical neurons, and is necessary for survival of striatal neurons in the brain. Expression of this gene is reduced in both Alzheimer's and Huntington disease patients. This gene may play a role in the regulation of stress response and in the biology of mood disorders. Multiple transcript variants encoding distinct isoforms have been described for this gene. [provided by RefSeq, Jan 2009]

Cell Cycle Mitosis Lab
Journal questions:
-
Based on your data and observations, what are some of the differences between
normal cells and cancer cells?
Cancerous cells seem to have fewer cells in Interphase than normal cells, if the sampling for this lab is any indication. Those cancerous cells also seem to have more cells in the prophase, metaphase, and anaphase than normal cells. All three of the cancerous cells in this lab (lung, stomach and ovary) had one cell in the slides that was in the telophase whereas non of the corresponding normal cell slides had a cell in the telophase.
-
When studying cell division in tissue samples, scientists often calculate a
mitotic index, which is the ratio of dividing cells to the total number of cells
in the sample. Which type of tissue would have a higher mitotic index, normal
tissue or cancerous tissue? Explain.
Cancerous cells would have a higher mitotic index than normal cells because they exhibit a higher rate of dividing cells than normal tissue cells.
-
Different types of normal tissues in the human body have different mitotic
indices. From the following list, which normal tissues would you expect to have
the highest mitotic index: muscle, skin, kidney, or lung? Explain your
answer.
Because various tissues of the body are replaced or renewed in cycles that are not identical, we see different mitotic indices; the mitotic index is a measurement of the cell division and that reveals the cycles inherent to that tissue group. Our skin regenerates more quickly than kidney tissue or muscle tissue for example. Because of this shorter life cycle, we would see a higher mitotic index for skin cells.

Review of other Blogs
After clicking to view a few blogs, my first impression is that I am ever the person who loves writing. I love learning and playing with ideas as well as writing to provide and exchange understandings. One observation is that we all do process information differently and respond differently even in the shared context of reading the written assignment instructions. Our answers reflect this; no two responses were alike!
I loved the way that Melanie's blog used blue color on the font to ease readability. No question it is organized and easy to grasp what information she provided in response to the assigned questions. In general, I appreciate that each blog has different color schemes and images.
I find that I wish I knew how to adjust and create Ariel as the default font. I am constantly highlighting and selecting Ariel because it defaults to a serif font such as Times New Roman. If I wasn't fighting this, I might have managed to spend time and adopt Melanie's font color decision which lends so much to both readability and organization of information.

Brain Tricks
After visiting http://braintricks.org/index.php , I lost at least 20 minutes of my life trying without success to figure out the visual clue for why moving one section of an image changed the number of people (drawn in caricature) from 12 to 13 or 13 to 12. Our visual center and its inherent processes are fascinating in their implications. Can we trust that we are seeing what really is there, and is there a there? Given quantum mechanics and the phenomena that what is seen depends on vantage point and whether you are looking at "it" or not suggests that no two people possible can share the exact same view. That's right, two people standing right next to each other watching a parade will each have different observations and will relate them differently as well. This means a lot when law enforcement interviews people who "witness" a crime.
Well, on to the assignment.... I scored 100 percent correct on the color blindness test, http://braintricks.org/test_score.php.
I then did the color perception test which asks people to look at the center cross. I quickly was able to see the green dot phasing or cycling through each position on the "clock" face, creating a ghostly green glow around each of the previously magenta dots. In the time I allowed, I was not able to see only the green dot or to have the magenta dots disappear altogether.
I could test this by staring intently, as I did in the above illusion test, at a particular object--my cell phone--and then quickly shifting my eyes to the space on the table near the cell phone and see if the ghostly image of my cell phone will appear. To form a theory, I would have to do this under controlled conditions, allowing for others to perform the test and then measuring their responses as well before determining if the evidence supports my hypothesis.
I have wondered about the ability of law enforcement to train themselves to be observant as they drive by, scanning for the unusual, the patterns that suggest crime, or the ability to elicit accurate information and assessment of that information for problem-solving duties. Sometimes I test my observation skills. I am beginning a new career in Asian medicine which relies on various skills, including powers of senses such as smell, vision, and touch to provide clues to the practitioner. Becoming aware of the sensory impressions literally at our fingertips as well as the scents that people carry and the sounds and sights that constantly are in our environments is a valuable exercise. it is not hard for people to smell if another has recently smoked a cigarette or eaten a meat sandwich or to detect the scent of their personal care products and cologne. It can be hard to train one's attention on one sound when another sound is more strident, or louder. It can be hard to find the right pressure to detect nuances in someone's pulse but using our senses and respecting the statements that people make about their experience of reality is what we work with. If they say they feel pins and needles in their legs, and we do not see any, well, we take in that information and seek other inputs as we work with people to resolve their concerns.
Conversely, trusting what we see that is not seen by others has value as well. Each of us has acuity that can vary according to genetics, awareness and state of alertness, and training or acceptance of sensory perceptions. Training oneself to not allow the brain to filter in ways it may choose to on an automatic basis is a challenge, but can deepen one's practice and yield interesting options.

Having seen this before, I gravitated to see how quickly I would find the hidden human face in the image above. Do you see it? Did you see it right away or was it a delayed response? I found it quickly.
My next choice was the audio test that asked for use of a headset. I put on a headset and discovered that the references for left and right were not congruent with my experience so I flipped the headset so that what was on one ear was now on the other and in fact, the references in the audio track were congruent. When the barber said he was positioning the clippers or the electric razor next to the right ear, that is where I heard it.
Forming a hypothesis about why I may see something that isn't there, the brain can be fooled to not see something that is there due to a structure in the brain so perhaps there is a structure that similarly explains why I may see something that isn't there. Sometimes a brain injury accounts for people who do not see a full face when looking at others.
Since a hypothesis must be tested, I will suggest that I can see something that isn't there due to the image staying on my retina longer, as when a person shifts their eyes and quickly the image of what they were gazing at persists for a moment or two longer. I imagine that this is a standard tactic in movie making cinematography to fool us into believing that a person was stabbed or fell off a cliff.
