Germany confirms two more swine fever cases in wild boar

HAMBURG (Reuters) – Another two cases of African swine fever (ASF) have been confirmed in wild boars in the eastern German state of Brandenburg, the state government said on Friday.

The new discoveries bring total confirmed cases to 34 since the first one on Sept. 10, all in wild animals, with no farm pigs affected.

All have been found in the region of the first discovery in the Brandenburg area.

Germany’s Friedrich-Loeffler scientific institute had confirmed the latest animals had ASF, the Brandenburg state government said.

China and a series of other pork buyers banned imports of German pork this month after the first case was confirmed, causing Chinese pork prices to surge.

The disease is not dangerous to humans but it is fatal to pigs and a massive outbreak in China, the world’s biggest pork producer, has led to hundreds of millions of pigs being culled.

A team from Osaka City University, in collaboration with other international partners, has demonstrated a reliable, precise, microscope-based thermometer using quantum technology that measures the temperature fo microscopic animals. The technology detects temperature-dependent properties of quantum spins in fluorescent nanodiamonds.

The research is published in Science Advances.

The optical microscope is one of the most basic tools for analysis in biology, using visible light to to observe microscopic structures directly. In the modern laboratory, fluorescence microscopy, an enhanced version of optical microscopy using fluorescent biomarkers, is now more widespread. Recent advancements in fluorescence microscopy have allowed for live imaging of the details of a structure, and through this, obtaining various physiological parameters in these structures, such as pH, reactive oxygen species and temperature.

Quantum sensing is a technology that exploits the ultimate sensitivity
