Scientists unravel the mystery of Paulinella, an ancient amoeba that consumed a bacterium to become photosynthetic

As part of a new research, an international team of scientists has attempted to solve the mystery surrounding Paulinella, a tiny amoeba that consumed a photosynthetic bacterium some 100 million years ago, keeping it alive to produce food through photosynthesis. The robbery allowed the ancient amoeba to exploit the bacterium's genes for photosynthesis, something that…



Canadian scientists design world’s smallest thermometer using DNA molecules

Scientists at Canada's University of Montreal have devised an incredibly advanced, programmable DNA thermometer 20,000 times smaller than a single human hair. Recently published in the Nano Letters journal, the breakthrough could enhance our understanding of natural and human-designed nanotechnologies, by allowing researchers to accurately measure temperature in nanoscale. According to the scientists, DNA molecules…



DNA in discarded cigarettes and chewing gum used to create stunning human-like masks

Our DNA is everywhere, in things we have touched as well as places we’ve been. Thanks to modern technology, our scattered DNA remains can be easily analyzed, revealing information about our unique genetic makeup. US-based artist Heather Dewey-Hagborg’s latest project is based on this idea. Titled Stranger Visions, it includes a series of stunning human-like sculptures built…


German scientists use DNA to construct the world’s smallest rotary motor

Nanotechnology’s stupendous growth in recent years has led us to something even more revolutionary: DNA origami. It refers to the highly-specialized technique of DNA folding, as a means to create two- and three-dimensional shapes in nanoscale. Using this technology, a team of scientists has developed what appears to be the smallest rotary engine in the entire…
