Chemical engineering for your "sugar-free" ice-cream
A story about your daily life with chemical engineering - if you are ice-cream lovers.
This is a tasty story from University of Connecticut:
"Ice cream’s semi-solid state is the result of a fragile balance of ingredients, and it’s no easy trick to replace old-fashioned sugar and still get the rich taste and texture that makes the Creamery’s ice cream so popular."

Open questions: seeking a holistic approach for mitochondrial research

Collaborate
Most of us are not geniuses, and cannot operate with an encyclopaedic knowledge of metabolism, calcium homeostasis, tissue physiology, bioenergetics and lipid chemistry. On the other hand, clinician scientists or physiologists who hope to incorporate mitochondria into their signalling paradigms feel overwhelmed with the complexity of the organelle, the experimental approaches, and sometimes, the dogma common to such established fields. The first step is an obvious one - forge meaningful collaborations that will truly push the field forward. I think we are finally past the point where non-mitochondrial scientists simply write us off, assuming that the mitochondria are a known entity, uninteresting, boring. Indeed the potential for fundamental new concepts in mitochondrial function has never been higher, and the disease relevance is clear. Mitochondrial pathways are practically untouched as a therapeutic target, for example.
For those of us working on the fundamental aspects of mitochondrial function, we must work harder to consider the physiology of real tissues. I’m not suggesting we abandon our fundamental projects, certainly not! Basic discoveries will remain the lifeblood of clinical development. But with collaborations we can extend our studies simultaneously and move into ‘real’ cells. Adapting these models will more rapidly push our discoveries up the ladder of biomedical translation. My own collaborations have provided me with confidence and helped me to understand complex physiologies that would otherwise have not crossed my radar screen. It sounds obvious, but funding agencies and promotion mechanisms do not always reward collaborations enough. Grants need a single principal applicant and team grants can be more political than functional. It is also clear that collaborations are more difficult than simply continuing along a successful, independent track. However, understanding the complexities of mitochondrial function and signalling will require open, and sometimes challenging, collaborations.

Nanyang Technological University produced a 3D printed concept car
Of course this is not the first 3D printer car, but it is good to see a group of students from Nanyang Technological University to get it done.
They are NTU Venture 8 & NTU Venture 9, both with round 150 parts are 3D-pritned.
For the NTU Venture 8, honeycomb structure and a unique joint design was employed, to ensure the car doesn't come apart. Also, the car chassis is see-through when hit by the light at the right angle. Presumably, most of the light will be absorbed by the solar cells so that the inside of the car doesn't heat up overmuch during summer.
NTU Venture (NV) 9, a slick three-wheeled racer which can take sharp corners with little loss in speed due to its unique tilting ability inspired by motorcycle racing.

What is photonics?
"Photonics is the science of light. It is the technology of generating, controlling, and detecting light waves and photons, which are particles of light. The characteristics of the waves and photons can be used to explore the universe, cure diseases, and even to solve crimes. Scientists have been studying light for hundreds of years. The colors of the rainbow are only a small part of the entire light wave range, called the electromagnetic spectrum. Photonics explores a wider variety of wavelengths, from gamma rays to radio, including X-rays, UV and infrared light.
It was only in the 17th century that Sir Isaac Newton showed that white light is made of different colors of light. At the beginning of the 20th century, Max Planck and later Albert Einstein proposed that light was a wave as well as a particle, which was a very controversial theory at the time. How can light be two completely different things at the same time? Experimentation later confirmed this duality in the nature of light. The word Photonicsappeared around 1960, when the laser was invented by Theodore Maiman.
Even if we cannot see the entire electromagnetic spectrum, visible and invisible light waves are a part of our everyday life. Photonics is everywhere; in consumer electronics (barcode scanners, DVD players, remote TV control), telecommunications (internet), health (eye surgery, medical instruments), manufacturing industry (laser cutting and machining), defense and security (infrared camera, remote sensing), entertainment (holography, laser shows), etc.
All around the world, scientists, engineers and technicians perform cutting edge research surrounding the field of Photonics. The science of light is also actively taught in classrooms and museums where teachers and educators share their passion for this field to young people and the general public. Photonics opens a world of unknown and far-reaching possibilities limited only by lack of imagination."
Photonics technologies are everywhere!

What is Software Engineering (軟體工程)?
Let's see how University of Oxford defines "Software Engineering"
"Software Engineering is the application of scientific and engineering principles to the development of software systems—principles of design, analysis, and management—with the aim of:
- developing software that meets its requirements, even when these requirements change;
- completing the development on time, and within budget;
- producing something of lasting value—easy to maintain, re-use, and re-deploy."

Invisibility cloak and metamaterials
What will you do if you are able to "disappear" or "invisible"?
A specially designed metamaterial may help you realize this. Prof. Sir John Pendry explained the idea in an article "Controlling Electromagnetic Fields" in 2006:
"Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields—electric displacement field D, magnetic induction field B, and Poynting vector B—are all displaced in a consistent manner. A simple illustration is given of the cloaking of a proscribed volume of space to exclude completely all electromagnetic fields. Our work has relevance to exotic lens design and to the cloaking of objects from electromagnetic fields."

LEGO and Scientific Researches
LEGO is my favorite toy when I was a kid. I enjoyed to build different spaceships and features with my limited Lego blocks. It was fun and and full of creation.
There are many different variations and products now for Lego. However, its' flexibility and simplicity (as basic building block) are remain unchanged. These allows researchers to easily build their own scientific tools for scientific experiments. But besides building robots, what else Lego can help researchers?

Carbon Dioxide Emission Pattern in one Year - the US, China, and Europe are the main polluters
Scientists at NASA modelling the movement of carbon dioxide in a year. In the video, as expected, the US, China, and Europe are clearly revealed as the main polluters. Watch the Youtube video below:
Here are some other findings in the video:
"Earth's carbon dioxide levels peak in the spring, and then drop in summer, when Northern Hemisphere plant growth absorbs gas from the atmosphere"
"In North America, the major emissions sources are in the Midwest and along the East Coast. Westerly winds in the Gulf Stream carry the greenhouse gas eastward over the Atlantic Ocean, the model shows"
"In Asia, the Himalayas block and divert winds that swirl around the high mountains. East of the Himalayas, these winds pick up carbon dioxide emissions from the industrialized Asian countries and carry the gas toward the Pacific Ocean"
"In the Southern Hemisphere, plumes of carbon dioxide and carbon monoxide rise from forest fires in South America and southern Africa"

Methane hydrate from the ocean
There is an article from NBC this morning "Climate Bomb? Methane Vents Bubble on Seafloor off east Coast: Study". It reports the possible methane leakage at the Altantic Ocean along the U.S. East Coast. The phase "Climate BOMB" caught my eyes. Definitely, on the bright side, scientists and engineers have been trying to catch this "BUBBLES" for our daily energy consumption.
