Scientists are launching a research study to check the effectiveness of a new type of flu vaccine that is made differently than the conventional vaccine, which is grown in eggs. The experimental vaccine instead relies on a cell line drawn from insects known as silk moths, which are better known for their role as pests attacking crops such as corn, cotton, barley and alfalfa.
The study of FluBlOk, made by Protein Sciences Corp. of Meriden, Ct., was initiated by flu expert John Treanor, M.D., professor of medicine and director of the Vaccine and Treatment Evaluation Unit at the University of Rochester Medical Center. The study will include a total of 400 to 500 adults ages 18 to 49 at three sites: Rochester, the University of Virginia, and Cincinnati Childrens Hospital.
Since the 1940s the chicken has been at the center of flu vaccination efforts, because fertilized chicken eggs are used to grow the flu viruses used in vaccines. Each egg contains less than a teaspoonful of material that will ultimately become part of a vaccine. Because of the complexity and sheer size of the process – tens of millions of eggs must be produced, and vaccine material must be "harvested" from each – its typically a six-month process to produce enough vaccine for the public, when everything goes well.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
