What do Smallpox, AIDS, SARS, Monkeypox, West Nile Virus, Chestnut Blight, Dutch Elm Disease, Sudden Oak Death Syndrome, Sea Otter Mortality and Avian Flu have to do with the world-wide disappearance of frogs and salamanders, otherwise known as "Amphibian Decline"? And with bait shops?
These diseases and their pathogens, with the unsuspecting support of humans and our global activities, all have been involved in microbial invasions of sorts. The transportation and sale of live bait is the latest example of a seemingly innocent human activity that may be responsible for spreading such diseases with dramatic ecological consequences.
Evidence for this comes from the genetic analysis of an emerging virus that has been implicated as a cause of infectious disease in amphibian populations in the western U.S. The genetic study indicates that the virus may have been transmitted to remote locations through the vector of live bait – infected salamanders being distributed and introduced to uncontaminated environments by fishermen and interstate bait wholesalers.

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,...
