Two Russian cosmonauts, Sergei Ryjikov and Sergei Koud-Svertchkov, and an American astronaut, Kate Rubins, came back on land without problems, Saturday, April 17 in the Kazakhe steppe, after a six-month mission aboard the International Space Station ( ISS).

A device coupled to the smartphone could snoop in the future coronaviruses in the breath. The underlying technique comes from the international space station.

In the context of professional sporting events, specially designed dogs have been specially designed in the US, which are intended to sniff up potential Covid19 infections among the spectators. A similar principle now follows the NASA, just puts on something more high-tech. A nanosensors equipped gadget called e-nose should be able to recognize at the breath of a person whether they are infected with the coronavirus.

I would say: The different types of material and patterns. I have created three different atmospheres and thus tries to bring the strong colors and materials together.

The technology was originally designed to measure air quality on the International Space Station ISS. Now it should be rewater for use for virus recognition. Thus this succeeds, the Ministry of Healthcare and United States Social Services is 3.8 million US dollars in the further development. "The portability, the low cost and the non-invasive nature of the device make it perfect for local community screening," explains E-Nose Inventor Jing Li the advantages of technology compared to common test procedures.

E-NOSE: This is how the digital corona snooper of the NASA

E-NOSE works measures volatile organic compounds in the breathing air. Thus, SARS-COV-2 can also be discovered because studies have already shown that the virus can be detected by such volatile organic compounds in the respiratory air. Scientists are now working to identify this specific breath profile. On this respiratory profile, the sensors of the e-nose should be tuned to detect coronavirus infections.

On April 24, in a speech, Joe Biden should officially recognize the Armenian genocide. US President Joe Biden should officially recognize the massacres of Armenians perpetrated under the Ottoman Empire during the first world war as a genocide said Wednesday, April 21 of the sources as a result of the file, which is likely to 'Tensioning between the United States and the Turkey .

A first field trial with the newly-quoted sensors should still be carried out in the spring 2021. The current prototype of the e-nose can be connected to a smartphone via Bluetooth. There, the data collected by the sensors are evaluated. Unless the field trial is successful, e-nose, according to NASA, can go directly into production and used in first clinical trials.

"As soon as the clinical trials are completed and the sensitivity and specificity are proven, e-nose can be used in factories, airports, grocery stores and companies of all kinds to quickly find active infections," says e-nose Data could then be analyzed by a KI together with the body temperature and other non-invasively recorded data to achieve more accurate results.
