Bioengineers at Dartmouth have genetically engineered yeast to produce humanized therapeutic proteins to address the manufacturing crunch currently confronting the biopharmaceutical industry. Reported in this week’s issue of Science, the researchers have re-engineered the yeast P. pastoris to secrete a complex human glycoprotein--a process offering significant advantages over current production methods using mammalian cell lines, according to the researchers.
The study, titled "Production of Complex Human Glycoproteins in Yeast," is one result of a collaboration between researchers at Dartmouth’s Thayer School of Engineering and GlycoFi, Inc., a biotech company located in Lebanon, New Hampshire. Founded in the spring of 2000 by Dartmouth engineering professors Tillman Gerngross and Charles Hutchinson, GlycoFi is advancing technology for the production of humanized proteins using fungal-based expression systems.
"For the first time, we have shown that yeast can be used to produce a complex human glycoprotein," says Professor Gerngross. "This technology has the potential to revolutionize the way therapeutic proteins are made--better, cheaper, faster, safer--and offer a level of control over the quality of the end product that has never existed before."

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
