Protein discovery in Chlamydomonas
A new protein discovery sheds light on how chemical information is transported within cells. A group of researchers, which includes Dartmouth Professor of Biological Sciences Roger Sloboda, have found the protein EB1 in Chlamydomonas, a single-celled organism commonly used to study cell biology. Previous research has implicated EB1 in the progression of many colon cancers.
Published in the November 11 edition of the journal Current Biology, the research examined the chemical motors that power events in flagella, antenna-like structures on some cells. Specifically, the research focused on intraflagellar transport (IFT), the process where proteins required for flagellar growth and maintenance move within the flagella. The discovery of the protein EB1 at the tip of the flagella on Chlamydomonas furthers investigations into the role the protein plays in flagellar function and perhaps in regulating IFT itself.

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
