This article provides a nice entry point to the field of biomimicry or biological inspiration. It gives 15 well-know and/or cool examples of biomimicry. However, there are so many more examples and after this article has been up for a few years (cannot find the exact date it was published) it feels a little outdated.

Efficient flying and swimming patterns of many organisms are the result of spiralic flows. After observing this fact, this company has produced a spiral shaped rotor. This technology would allow for devices to be smaller, is more energy efficient than current rotors, and is also significantly quieter, compared to current technology such as jet engine turbines which are extremely noisy. This technology also has many applications, as there are many needs for fans, impellers, and pumps in transportation, industries, and residences.

After the discussion of extending life in class today I remembered reading about recent advancements and claims that have been made about extending the human life. After looking around I found this great article that tracks recent scientific findings and possible "cures". In the quest for longer life, scientists are trying to find the genes of longevity and bottle their benefits for all. However, the purpose of this research is not extreme life span but something they call "health span." Rather than getting certain diseases early in life such as heart disease and other age dependent illness, these illnesses will merely happen much later in life. Aging, after all, is not a disease but a natural process, the accumulation of defects that our bodies simply do not have the wherewithal to repair. A large portion of the article discusses the hypothesis that calorie restriction reduces the creation of toxic molecules called free radicals, which are considered crucial factors in the aging of cells and tissues. Another hypothesis is that calorie restriction decreases the secretion of certain hormones-in particular, insulin and insulin-like growth factor-that signal organisms to channel their resources into either growth and reproduction (when insulin and IGF levels are high) or maintenance and repair (when they are low). The article also discusses the work of Dr. Grey. Dr. Grey believes solving the fight against aging involves dismantling and hauling out the molecular trash while also delivering engineered gene and therapeutic cells to refurbish cells that have died out and gone unreplaced. He believes that other scientists' focus is too small, and it is easier to just clean up the mess rather than mess with pathways and mechanisms. Dr. Grey believes that the possibility of a shot to cure aging is a lot closer than we think.

Exellent review of the paper. And interesting view-point of this Dr. Grey.

I mean: Excellent review ;-)

This is a pretty short but interesting article about bullet trains in Japan. Although the trains are extremely fast, they were very noisy when coming out of tunnels due to the air pressure difference created when they exited the tunnels at such high speeds. Therefore, engineers designed the nose of the train after the kingfisher's beak because the kingfisher is a bird that can dive into water at high speeds with very little splashing.

In this TED talk Paul Wolpe discusses the current excels in bioengineering and whether there is a line that needs to be drawn. According to Paul, man has undergone three major waves of evolutions: Darwinian Evolution (passive), Civiliization (controlling the evolutionary environment), and Directed Evolution (design). For the first time in history man is intentionally designing and altering the physiological forms that inhabit our planet. In the speech, Paul posses the question of what are the "ground rules" for bioengineering and creating life by depicting the work we have done so far. The majority of food in the supermarket today already has genetically modified aspects of it without clear regulations or identification on the packages. Are the benefits that may come from genetically modifying organisms worth the manipulation of nature? Paul also talks of recent successfull experiments in which scientists have been able to control animals through computer technology. An "Organic Robot". What do you guys think? Is it right for us to modify animals in order to benefit ourselves? Where is the line drawn? This is no longer science fiction, but a reality.

This short article discribes the accomplishements in robotics made by Mirko Kovac, a robotics engineer. It goes into detail about his break-through in the "perching" methods that stemmed from his grasshopper-inspired robots. There is also a brief video clip that essentially describes the "perching" process of his robot. I was really amazed to find that these robots are actually programed to run into whatever object they are looking for without being harmed!

Be it that we are nearing the end of the class, I found this video to be a very good summary of what we have covered in the class and what we can take away from it. The video is based upon the new movement of finding design inspiration from nature (Biomimicry). For this specific interview, they focus on an interview with Robert Full to educate the viewer about engineering inspiration from nature. If you remember, Robert Full believes that evolution doesn't necessarily design the perfect mechanism, but rather the mechanism that allows the animal to survive. Therefore, we as humans are able to learn from the abilities of animals gained from evolution and further refine the specific ability to be more efficient and applicable to our needs. The video covers a bunch of the innvoations we have discussed during our time in class including the gecko robot and the running robot RHex. I think this would be a nother great video to show in the beginning of the class for next semester. It presents the general idea of BioInspiration, provides examples of research and application, and also discusses the great importance it will play in the future; building more efficient and useful technology.

This a great talk on Solar Energy and a new innovative way to improve on our current notion of solar energy. According to Bill Gross, current solar panels that rely on silicon and other materials are still not cost effective enough to be practical. I most cases, it takes more energy to make a solar cell, than it will give out in its entire life. This led to the challenge of finding other ways of making cost-effective solar energy for use in our society. The talk covers Gross's solution of collecting the sun using reflectors to concentrate the energy to a small converter, how to design these reflectors, and what converter would be used to turn this solar energy into usable energy. In order to solve the problem of finding the most effective way of capturing/reflecting the rays of the Sun Gross used Genetic Algorithms. The use of Genetic Algorithms is a powerful way of solving intractable problems using "natural selection". You take a problem that you can't solve with a pure mathematical answer, you build an evolutionary system to try multiple tries at guessing, you add sex - where you take half of one solution and half of another and then make new mutations - and you use natural selection to kill off not as good solutions. This process ultimately led them to some great ideas for reflectors. In order to capture this heat from the solar rays Gross utilizes an advanced Sterling Engine mechanism. In summary, I highly suggest that everyone watch this video and see these alternative methods of capturing and converting solar energy.
