We all know that a viral infection can be developed extremely quickly, but in fact its even more dramatic than that - the process is literally explosive.
The pressure inside a virus is 40 atmospheres, and it is just waiting for an opportunity to blow up. The virus is like a living DNA cannon. How this cannon functions has been mapped by Dr. Alex Evilevitch at the Department of Biochemistry at Lund University in Sweden. This is knowledge that will have applications in gene therapy, drug development, nanotechnology and the treatment of infections. This involves a new type of virus research that is based more on physics than biochemistry. Perhaps it could be called virus biophysics. Alex Evilevitch took his doctorate at Lund in physical chemistry and worked for a few years at UCLA.
"There I met Professor William Gelbart, who predicted on theoretical grounds that the pressure in a bacteriophage - a virus that attacks bacteria must be 40 atmospheres," explains Alex Evilevitch. "This roughly corresponds to the pressure at a depth of 400 meters under the sea. Thats twenty times more than the pressure in a car tire and ten times more than the pressure in an unopened bottle of champagne. Using measurements, I was able to confirm that Professor Gelbarts prediction was accurate."

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,...
