Edison’s Cradle?

Supplementing the Newton’s Cradle post, Behold the Edison’s cradle ! :) 

As part of his senior thesis exhibition at Musashino Art University in Tokyo, art student Yasutoki Kariya re-imagined the ubiquitous desktop gadget, Newton’s Cradle, using a lovely sequence of light bulbs. 

Entitled Asobi(which translates roughly as “playing“) the 11-bulb installation creates a visual interpretation of the popular toy named after Sir Isaac Newton demonstrating his third law of motion regarding momentum: that for every action there is an equal and opposite reaction. 

The ingenious deception.

However, instead of actual energy created by the kinetic force of steel balls, Kariya devised a method for using programmed light and two surreptitiously placed pistons to create this purely visual experience that’s arguably more mesmerizing than the original concept.

Synthetic membranes created to mimic properties of living cells

Living cells continually remodel their membranes to change their physical characteristics, a process that can affect the behavior of other biomolecules in the cell membrane.

Biochemists at the University of California San Diego have developed artificial cell membranes that grow and remodel themselves in a manner similar to that of living mammalian cells.

The achievement, detailed in a paper published in this week’s issue of the Proceedings of the National Academy of Sciences, follows the successful design last year in the same laboratory of artificial, or synthetic, cell membranes capable of sustaining continual growth. The two developments now bring the researchers closer to mimicking all of the properties of living mammalian cell membranes with synthetic components.

That’s important because synthetic membranes that accurately mimic the behavior of living mammalian cell membranes could be used by biomedical researchers to develop more effective drugs that target membrane proteins and better understand the chemical changes that occur in dysfunctional membranes during disease.

“While artificial membranes have been used to model the properties of native membranes, previous methods have not been able to mimic lipid membrane remodeling,” said Neal Devaraj, an associate professor of chemistry and biochemistry at UC San Diego who headed the research team for both studies. “In our latest study, we show that reversible chemical reactions can be harnessed to achieve spontaneous remodeling of lipids in synthetic membranes.”

A hypotrochoid is a roulette traced by a point P attached to a circle of radius b rolling around the inside of a fixed circle of radius a, where P is a distance h from the center of the interior circle. The parametric equations for a hypotrochoid are:

x=(a-b)cost + hcos[(a-b)t/b] y=(a-b)sint + hsin[(a-b)t/b]
