An important asset of life was first discovered from a great height


Put your hands in front of your face. For most people, they are replicas of each other: you can hold them from palm to palm, they are convenient, but you can not overdo it.

Molecules express this manipulation. It is organized in two reflective and non-exaggerated forms. It is a wonderful joke of life that almost all living atoms function in only one of its two forms.

Natural amino acids – the building blocks of proteins – are always left, or cabinet. On the other hand, natural polysaccharides like RNA and DNA are always right-handed or dextral. If you replace any of these molecules differently, the entire structure collapses.

This trick is called homochirality. We don’t know why this happens, but it’s an important life asset. Scientists have now discovered the molecular homogeneity of flying at 70 kilometers (43.5 miles) per hour from a helicopter at an altitude of 2 kilometers (1.2 miles).

You ask why would they do such a thing? In search of extraterrestrial life, see if we can find molecular homosexuality on other planets. It would be helpful to be able to measure this signal from a height, even on the ground, as it can reveal information about plant health.

“When the light is reflected by biological agents, a portion of the electromagnetic waves of the light travel clockwise or counterclockwise.” Physicist Lucas explained Grandma from the University of Bern in Switzerland.

“This phenomenon is called circular polarization, and it is caused by homozygosity in the biological material. Similar light coils are not formed by azionic inertia.”

As you might expect, this sign is very dizzy. The circular polarization of plants is less than 1% of the reflected light.

One type of instrument that can detect a polarized light signal is called a spectrophotometer, which uses special sensors to separate the polarized region. For many years, Grandma and her team have been working on a highly sensitive spectrophotometer to detect the circular polarization of plants. It is called tripol, and it positively detects a circular pole from a distance of several kilometers.

Now, they’ve modified the aircraft’s tripod, adding spectrometers and temperature controls for the optics. This new design is called a flypole.

When Grandma and her team flew over Wall-de-Travers and Le Local in Switzerland using a flypole, the progress these improvements provided were immediately evident.

“The notable improvement is that these measurements are made on a moving and vibrating platform, and we detect these biometric fingerprints in a few more seconds.” Astronomer Jonas Kohn said: from the University of Bern, and the Mermos project (observation program with modern ether surfaces with polar properties).

Flyball is not the only one that can isolate the circular polarization signal and distinguish it from malicious surfaces such as asphalt roads. The team can use it to distinguish between different types of plants, such as grasses, forests and algae in lakes – all from a fast-moving helicopter.

The researchers said this could open up a new way to monitor the health of various plant ecosystems, even coral reefs. But they haven’t revised it yet. They want it to travel at a speed of about 27,580 km/h and an altitude of 400 km – in low Earth orbit.

“The next step we want to take is to make similar discoveries from the International Space Station (ISS), looking at Earth.” Astronomer Brice Oliver Demarie said: University of Bern and Mormos.

At this altitude, the accuracy may not be as high as 6 to 7 kilometers – but researchers can help fine-tune their polarimeter spectrophotometer and see how well it performs in more intense measurements.

“This will allow us to assess the discovery of biological codes on a planetary scale. This will be a crucial step in the search for life in our solar system and beyond the use of polarization.” Demore said.

The search has not yet been published Astronomy and astronomy.
