Candles in microgravity
Think about how hot air rises while cooler, denser air sinks.  This all happens due to gravity here on earth, but what would happen without this force of nature?  If the air isn’t rising or sinking around the flame, then how does the air mix to supply fresh oxygen to the candle to keep it burning?  
UC San Diego student, Sam Avery is trying to understand this by taking his team aboard NASA’s Zero-G airplane.  The flight follows a parabolic path and causes a dozen or so 30 second bursts of zero gravity.  During this time Avery can ignite a flame in a special chamber to observe the effects of microgravity.
He led a team last year doing a similar experiment.  During that time the flame was still able to burn, but at a much lower rate.  It was able to get new oxygen to burn by a process known as molecular diffusion.  So, why does it matter? By doing these tests, scientists can better understand a flame’s burn rate and possibly lead to developing more efficient biofuel engines.

"German artist Sarah Schönfeld has squeezed drops of various recreational legal and illegal liquid drug mixtures onto exposed negative film for ‘ All You Can Feel’, a photography series that visually reinterprets the physiological and psychological imbalance of substances in the body. Much like the chemical effect of some of these substances on humans, the resulting shapes and colors showcase some of the unique characteristics of each drug, each revealing a vivid, and intricately particular internal universe. By enlarging the chemical reaction of each drug, ‘all you can feel’ portrays the unknown interface between representation and reality.” ©sarah schoenfeld

A Moveable Yeast: modeling shows proteins never sit still
Our body’s proteins – encoded by DNA to do the hard work of building and operating our bodies – are forever on the move. Literally, according to new findings reported by Trey Ideker, PhD, chief of the Division of Genetics in the UC San Diego School of Medicine, and colleagues in a recent issue of the Proceedings of the National Academy of Sciences.
Hemoglobin protein molecules, for example, continuously transit through our blood vessels while other proteins you’ve never heard of bustle about inside cells as they grow, develop, respond to stimuli and succumb to disease.
To better understand the role of proteins in biological systems, Ideker and colleagues developed a computer model that can predict a protein’s intracellular wanderings in response to a variety of stress conditions.
To date, the model has been used to predict the effects of 18 different DNA-damaging stress conditions on the sub-cellular locations and molecular functions of more than 5,800 proteins produced by yeasts. They found, for example, that yeast proteins could move from mitochondria to the cell nucleus and from the endoplasmic reticulum to Golgi apparatus.
Though the model debut involved yeasts, researchers said the coding can be adapted to study changes in protein locations for any biological system in which gene expression sequences have been identified, including stem cell differentiation and drug response in humans.

Fluorescein

This chemical is a fluorophorecontaining many aromatic groups and having the ability to absorb light and re-emit a new photon (fluorescence). There are other types of fluorescence that allow re-emission of light at higher energies or even the same energy but in this case the re-emitted light is at a lower energy. Because it is under a UV light, it absorbs the UV and the light that it re-emits will be visible to human eyes. Sadly, what we can see is only a very narrow band of the spectrum, still pretty awesome!
