Private Notes
Parents want the best for their child. But never before has their uncertainty about education been as great as it is today. And parents have never been so critical: there is talk of tyrant children, tiger mothers and helicopter parents. Most children, on the other hand, assess their parents' upbringing positively. What's good parenting today? And what is really important?
The Cambridge Analytica case has shown how our data traces are used on the Internet today and how we can be manipulated. Quarks explains how Facebook and other big corporations collect our data, what the algorithms do with it and how they make money with it - and how they learn things about us that we would never actually reveal.
Over the last 27 years, even in protected areas, the number of insects has fallen by more than 75%. An alarm signal, because fewer insects could soon mean fewer fish, lizards, birds and mammals. Insects are the foundation of a healthy nature. They are pollinators for flowering plants, keep pests at bay and are food for many animals. If the insects die, other animals and many plants also threaten to disappear. Quarks clarifies a topic that currently not only concerns environmentalists, scientists and politicians, but also many other people in Germany.
A harmless research on superfoods unexpectedly turns out to be a science scandal involving top universities, top researchers and even a science minister. More and more often, scientists publish their research results in Open Access journals, which also print "scrap studies" without quality control. Experts are sounding the alarm that the whole system is under threat if more and more bad research is circulating under the guise of science. How does the system work in practice? The author Peter Onneken has tried it. With the claim: Chia seeds make clever, he made it in trade journals and at conferences. But poor research can also harm the consumer, especially when it comes to life and death.
Some are disgusted, others panic: Jellyfish seem to be gaining ground. More and more frequently, they are seen on the beach or are painfully hit by their stinging cells. But jellyfish also have amazing abilities. Torn off body parts grow back, some species adapt extremely well to difficult environmental conditions and some are even immortal. It seems they own the future. But their success can become a problem for us humans.
Only apparently we are on safe ground. Because the ground below us is by no means as stable as it seems at first. It's crawling with cavities. The causes are manifold: natural holes, man-made holes or underground explosions leaving huge holes. How high is the risk of being swallowed by a hole in the ground? What are the causes? And what can we do about it?
It's about the great mystery of human history: Why did the Neanderthals die out? They were evolutionarily our cousins and populated Europe before us. And quite successfully. For 200,000 years they survived ice ages and adverse living conditions here. But when Homo Sapiens, our direct ancestor, enters European soil, they disappear. Until about 160 years ago, quarry workers found their bones in Neandertal, in the middle of North Rhine-Westphalia between Düsseldorf and Wuppertal. And so that spectacular scientific history can be written: the mystery of the identity and demise of the Neanderthals begins.
Why did they die out? Was perhaps the mating between the Neanderthal man and modern man to blame? Or did Homo Sapiens bring a pathogen they weren't prepared for? Quarks pursues the most important and exciting theses!
Volcanic eruptions have shaped life on Earth. They are also blamed as the cause of many mass extinctions in the history of the earth. Such super volcanoes can devastate entire continents and change the world climate over centuries. They erupt very rarely - the last eruption of this strength occurred over 25,000 years ago. But the danger is not averted and at some point there will be another outbreak - the only question is: when? Quarks shows how a super eruption would affect us here in Germany today and how we could deal with such a global catastrophe.
