The symbiosis of fish farming and vegetable growing in a closed system, the so-called aquaponics, is on the rise in the Czech Republic. In order for business to be not only profitable, but also maximally ecological, it is necessary to balance a delicate balance in the system, which would suit both fish and plants. The researchers from the Brno University of Technology and the Institute of Global Change Research of the ASCR (CzechGlobe for short) have now come up with a solution. Together with Flenexa, they mapped the nutrient flow in the aquaponic farm, designed a model to predict the behaviour of the system and, according to the first laboratory tests, selected algae that should help make high-tech farming more efficient.

From the sand dunes in the Sahara Desert to the freezing Svalbard, an international team of researchers from the University of Hawaii and the Faculty of Mechanical Engineering of the Brno University of Technology watched total solar eclipses everywhere for fourteen years. They recently summarized their latest findings in an article for the prestigious Astrophysical Journal Letters, and NASA notes the article on its website. Thanks to their measurements, experts determined the sources of different solar wind currents in the solar corona.

A small drone adapted for monitoring the presence of invasive plant species. This is one of the results of long-term cooperation between the Brno University of Technology and the Botanical Institute of the Academy of Sciences in Průhonice. While a functional sample of an improved aircraft is being created at the Institute of Aviation of the Faculty of Mechanical Engineering, botanists are tuning algorithms to automatically detect non-native plants in the obtained data. The system is intended to facilitate and reduce the cost of monitoring non-native species, such as the dangerous Heracleum.

An inconspicuous sensor on the rail, which detects any vibrations and excitements, sends a signal and artificial intelligence evaluates the potential risk. According to experts from FME, this could be a recipe for increasing safety on the railway.

If the respirator does not seal well, its effectiveness decreases and it protects less from the spread of infection. Face shields capture only large droplets, but not the aerosol. Why is it important to ventilate? Can air purifiers help? Questions related to the aerosol effects on the spread of coronavirus are answered in detail in a document by German experts. Their colleagues from the Brno University of Technology, the Institute of Chemical Processes of the Academy of Sciences of the Czech Republic and the Czech Metrology Institute under the auspices of the Czech Aerosol Society translated it and offered it to the public.

A small catheter with a nozzle at the end that applies highly concentrated chemotherapeutics in the form of a spray exactly where they are needed. Last year, David Hoskovec, the head of the 1st Surgical Clinic of the General Hospital in Prague, came up with such a vision. He asked the Czech manufacturer of medical and rescue aids, the company SKALA-Medica, which took over the development. Specialized measurements were then supplemented by experts in fluid mechanics from the Faculty of Mechanical Engineering, Brno University of Technology.

It can be folded into a wheelchair, hitched to a car and taken anywhere. This is one of the advantages of the MoLiS system, a mobile airport lighting system developed by TRANSCON ELECTRONIC SYSTEMS in cooperation with the Aviation Institute of the Faculty of Mechanical Engineering at BUT. MoLiS could replace obsolete systems at small airports, which are dying in many places. However, it can also be used as a backup system for large airports, or in the event that it is necessary to prepare a runway in a place that does not normally serve as an airport.

Brno scientists came up with new technology for water purification using low-temperature plasma. The device can remove chemical residues from water, such as oestrogens from contraception, and also kill pathogenic microorganisms such as cyanobacteria and bacteria.

The image of the solar corona, which was seen during last year's total solar eclipse over South America, is today's NASA Astronomy Picture of the Day (APOD).

Tens of millions of car radiators are produced annually in Europe alone. They are usually made of metal, but experts from the FME have been working for several years on the development of a completely new type of a radiator made of hollow polymer fibres.

Professor Jiří Jaromír Klemeš, from the Faculty of Mechanical Engineering BUT, has been named on the annual Highly Cited Researchers 2020 list from Clarivate Analytics.

In case the aneurysm ruptures, half of the patients die. While smaller aneurysms are usually only closely watched by physicians, larger ones are usually operated on.
