Popular Science: How much food do Czech households waste?

Food waste is a global problem. According to the FAO (Food and Agriculture Organisation, UN), 1/3 of the food produced worldwide – 1.2 billion tonnes – is wasted each year. Data provided by the EU indicate that 20% of food in Europe remains unconsumed. Countries around the globe have all agreed on the urgent need to reduce such waste. For example, as part of target 12.3 of the Sustainable development goals (SDGs) programme, member states of the UN have called for per capita global food waste to be halved by 2030. To achieve these goals, detailed monitoring is essential. However, reliable and coherent data are often missing. An analysis by Petra Novákovás (Faculty of Science alumna), which I am going to introduce in this article, should help fill some of these gaps. Svatava Janoušková from the Faculty of Science, Charles university, also collaborated in this research.

Popular Science: Czech polar explorers are ready for the future

Predicting potential future changes in the landscape is based on knowledge of the current state and changes in the past. A group of experts, led by Stephen J. A. Jennings from Masaryk University in Brno, have now finished mapping the inhospitable area of the Ulu Peninsula, which could provide a window into the future development of other areas of the Antarctic Peninsula. Zbyněk Engel from the Department of Physical Geography, Faculty of Science, Charles University, who has been travelling to polar research expeditions since 2009, played a significant part in this research.

Popular Science: Is iron the new star in cancer treatment?

Cancer, an insidious disease, affected over 19 million people and killed almost 10 million worldwide in 2020 alone. Thus, it is no surprise that searching for new and more efficient treatments is still a top priority for scientists and the public all over the world. Targeted treatment has attracted special attention in the last few years because of its ability to limit the adverse effects of conventional chemotherapeutics. New approach to targeted treatment has now been developed by teams led by Dr. Jaroslav Truksa and L. Werner from the Institute of Biotechnology of the Czech Academy of Sciences (IB CAS). This approach is described in detail in a publication, whose main author was Cristian Sandoval-Acuna (IB CAS) and which was produced in collaboration with Faculty of Science of Charles University and the Institute of Molecular Genetics CAS.

Popular Science: Small is nice? And sometimes toxic.

Microplastics are a topic of today. They are everywhere, in water, in soil, in the air, and even in remote areas such as the Arctic. The study of the interactions of microplastics and common organic pollutants has so far focused mainly on the marine and other aquatic environment. However, their presence in the soil is one order of magnitude higher than that in the oceans. Tereza Černá, a doctoral student from the Department of the Environment at the Faculty of Science, Charles University, together with a group of experts, made an experiment on the interaction of soils containing polycyclic aromatic hydrocarbons (PAHs) and polyurethane foams. And what was the result?

Popular Science: Why do we yawn (longer than birds)?

Summer, warm weather, dark room, and a boring lecture – a moment when anybody would like to yawn, but it is just not appropriate. Certainly, many of us have asked themselves: Why do we yawn in the first place? Numerous scientists have posed the same question, the result of which is a variety of different answers circulated among people. The most popular one says that yawning helps to oxygenate blood. As surprising as it may be, this theory was debunked over 30 years ago. Then, why do we yawn? Do other animals yawn in the same way we do? These questions can now be answered through a new study – the largest ever conducted on yawning – by an international team of scientists, including students from the group of Mgr. Pavel Němec, Ph.D., from the Department of Zoology at the Faculty of Science, Charles University.
