Popular Science: How do we choose a partner? Do partner preferences remain stable throughout a relationship?

Choosing a partner is a key decision in a person’s life. What characteristics do we look for in a partner? Does our notion of an ideal partner change during a relationship? These are some of the questions asked by scientists Radka Kučerová, Zsófia Csajbók and Jan Havlíček from the Charles University. Their most recent paper examines ideal partner preferences and how they change during a relationship.

Popular Science: Understanding the power of honey through its proteins

Popular Science: Understanding the power of honey through its proteins

Honey is a culinary staple that can be found in kitchens around the world. Humans have used honey throughout history, and its long shelf life and medicinal properties make it a unique, multipurpose natural product. Although it seems that a lot is known about the sweet substance, surprisingly little is known about its proteins. Now, researchers report in ACS’ Journal of Natural Products new data on honey proteins that could lead to new medicinal applications.

The role of nomadic pastoralists in the genetic history of the Sahelian/Savannah inhabitants

The role of nomadic pastoralists in the genetic history of the Sahelian/Savannah inhabitants

Previous archaeological and linguistic research suggested that the prehistoric population of the Sahel and adjacent savannahs diversified over time into sedentary farmers and nomadic pastoralists. A team from Czech, Senegalese, Sudanese and Portuguese institutions, including Martina Čížková, Iva Kulichová and Viktor Černý from the Department of Anthropology and Human Genetics and Pavel Munclinger from the Department of Zoology from the Faculty of Science, decided to verify this hypothesis using molecular-genetics methods.

The blue-green world of deep-sea fish

An international team of scientists, including lead co-author Zuzana Musilová from the CU Faculty of Science, recently discovered that some deep-sea fish possess a unique set of photosensitive pigments that probably enable some form of colour vision, even at great depths. The article was published as the cover story of the most recent issue of the world's most prestigious scientific magazine, Science.

Are intestinal parasites of great apes and humans as closely related as their hosts are?

Are intestinal parasites of great apes and humans as closely related as their hosts are?

The clinical detection and identification of Entamoeba (intestinal parasites) is usually performed using light microscopy, which is often complicated and imprecise. An international team from Czech, Belgian and Swiss institutions, including Jakub Kreisinger from the Department of Zoology, Faculty of Science, has developed a new and more effective approach consisting of advanced molecular methods. It is also the first comparison of the Entamoeba lineages in humans and wild great apes.

A focus on golf courses: devastation or a chance for nature?

A focus on golf courses: devastation or a chance for nature?

Golf courses are now a natural part of our landscape. Although their history in our country dates back over 100 years, recently their development has been more rapid. Along with accelerated construction, an increased interest in this phenomenon has begun, both positive and negative. Positively, golf courses can be seen especially in connection with land reclamation, yet if they are built on high quality agricultural land, the views differ. What is their current state of development since 1990, and how do they affect the landscape? From the University of South Bohemia in České Budějovice together with specialists from our faculty—Přemysl Štych from the Department of Applied Geoinformatics and Cartography and Dana Fialová and Lenka Svobodová from the Department of Social Geography and Regional Development—a team of scientists focused on this question.

How does climate affect plant traits?

How does climate affect plant traits?

Irena Šímová from the Department of Ecology of the Faculty of Science, Charles University, is one of two main authors of a study, in which scientists from a total of 23 workplaces across Europe and America participated. Its main objective was to find out what traits of woody and herbaceous plants on the American continent are affected by the climate. For the analysis, scientists used data in the BIEN and TRY databases. They contain extensive datasets on occurrences of plant species and plant traits. Woody plants have revealed a clear influence of the climate on individual traits. These two growth forms of plants - trees and herbs - seem to have different life strategies.

If I stridulate, you won’t eat me, will you?

If I stridulate, you won’t eat me, will you?

Stridulation is a type of acoustic signaling, which is quite widespread in various arthropods. Nevertheless, people usually associate these sounds (created by rubbing certain body parts together) mainly with insects, probably mostly with crickets. Have you heard that spiders can also stridulate and that it is obviously quite common behavior for them, as it has been documented in more than 30 spider families so far? However, the function of stridulation is still not known in many species and that is why a team of scientists from Prague and Brno universities, including František Štáhlavský from the Department of Zoology from the Faculty of Science, studied spiders of the genus Palpimanus.

Behind the fog as thick as pea soup and even further…

Behind the fog as thick as pea soup and even further…

...we often find our country. This is because in the “Czech basin surrounded by mountains”, fog is a relatively frequent phenomenon, in part because of the geomorphology. We talk about fog when a cloud of suspension of water droplets reduces the visibility to less than one kilometer in at least one direction. If the visibility is from 1 to 2 km, it is called mist and from 2 to 5 kilometers, haze. The most intense fog in terms of visibility and density is found in the mountains, where they also have a significant impact on the water balance, so we can talk about a major influence on the mountain ecosystem. In the lowlands, fog does not occur as often. In urban agglomerations, however, the occurrence of condensation nuclei formed by aerosol particles with radii from 10-8 to 10-5 support its occurrence. At the same time, the high levels of pollutants present a great danger. Individual places in Czechia differ not only in intensity, range and type, but also in the fog frequency, from only tens of days to almost 300 days a year. Several studies from different parts of Europe show a decrease in fog frequency due to either climate change or an improvement of the ambient air quality. And how does the long-term trend look in our territory? A group of scientists under the leadership of Iva Hůnová from the Institute for Environmental Studies is dealing with the question.

Popular Science: I SENSE A FIREBUG NEARBY…

Popular Science: I SENSE A FIREBUG NEARBY…

Animals are naturally trying to avoid becoming prey. Some depend on perfect camouflage, some prefer a hidden lifestyle, and some are equipped to defend themselves actively. However, even a wasp with a pointed stinger would rather fly away instead of fighting for its life. Could it somehow warn a potential predator ahead then? Aposematic signals have evolved for this exact reason. Aposematism is a easily-noticeable warning signal informing the recipient that the signaling animal is distasteful, venomous or otherwise dangerous. The striking yellow and black colors of wasps, newts or yellow-bellied toads are just that. Nevertheless, aposematic signals don’t end with coloration. Sometimes a smell is the best way to demonstrate how dangerous or distasteful one is. Whether a smell is truly a strong enough sign was investigated by a team of zoologists of the Faculty of Science, Charles University, led by Jan Raška.

Popular Science: Is there a danger from arctic mosquitoes?

Mosquitoes are known to be carriers of a wide spectrum of dangerous diseases. In this regard, tropical diseases, e.g. malaria, are the most well-known ones. However, we can also find some of them in the polar regions. A research team led by the Institute of Parasitology of Biology Centre CAS in České Budějovice focused on a survey of dangerous viruses in mosquitoes in the Arctic.
