New York engineering firm Pliant Energy Systems have developed a robot that uses undulating fins to propel itself. The fins allow the robot to move easily over different terrains like water, ice and sand.


Measuring Network Effects


Andreessen Horowitz have published a handy post listing the different types of metrics that can be used to measure network effects in software and marketplace businesses. The list progresses from the basic organic vs paid users metric up to metrics like market depth and unit economics.




Coglode are back with another great behavioural pattern called Reactance. This is the scenario where controlling people's sense of freedom can trigger an angry motivation to regain it. An example in commerce is an online shop to uses too many scarcity game dynamics to scare the user into purchasing because there are only "2 seats left at this price" and the "offer ends in 2 minutes 12 seconds". Reactance occurs when the user is so put off by this that they decline to purchase anything out of spite.


Air Scrubber Ivy

Researchers at the University of Washington have genetically modified a pothos ivy houseplant to remove chloroform and benzene from the air around it. The modified plants express a 2E1 protein that transforms the cholorform an benzene into molecules that the plants can then use to support their own growth.

Developer Benjamin Groessing has developed and released, a free service that removes background from uploaded images using python, ruby and deep learning.
