Another week has passed and it’s time to take a look at the some headlines from last week. As always, if you would like to receive these news and other good stuff, please register for our email newsletter.
1. Advanced Biological Computer Developed (May 24)
Scientists at the Technion-Israel Institute of Technology have developed and constructed an advanced biological transducer (a computing machine capable of manipulating genetic codes) using only biomolecules (such as DNA and enzymes). This breakthrough might be used for individual gene therapy and cloning.
“In addition to enhanced computation power, this DNA-based transducer offers multiple benefits, including the ability to read and transform genetic information, miniaturization to the molecular scale, and the aptitude to produce computational results that interact directly with living organisms,” said the lead researcher Prof. Ehud Keinan from the Technion Schulich Faculty of Chemistry.

There might be more “dark stuff” than we have expected out there
2. Experiment Investigates How Classical Physics May Emerge from Quantum Physics (May 24)
One of the most interesting topics in quantum mechanics is the transition between quantum world and the classical physics world. In particular scientists are interested in how classical physics behavior can emerge from quantum physics. Now, a new experiment by the scientists from Stony Brook University in New York might shed some light on this problem.
“Our results suggest that classical physics may emerge in a very natural way in large quantum systems—in this case, ‘large’ meaning just two coupled subsystems—without the invocation of an external ‘environment’ responsible for decoherence,” said physicist Bryce Gadway.

3. Different Types of Dark Matter Might Exist (May 24)
A new paper by a team of Harvard physicists has proposed an existence of a different type of dark matter — one that is not cold and collision-less. If true, this would imply that there might be dark atoms, photons and even some form of dark electromagnetic force as well. In turn this could imply the existence of dark galaxies.
