The most important climate factors

How sun, clouds, CO2 and other factors determine the climate. The video clip was created in collaboration with meteorologist Prof. Dr. Stephan Borrmann, Professor at the Johannes Gutenberg University Mainz and Scientific Member at the Max Planck Institute for Chemistry, and climate scientist Dr. Di

Attack of retroviruses

Like other viruses, retroviruses attack cells and force them to produce more retroviruses. This is only the first stage of the attack, because retroviruses implant into the genome and become part of our DNA.

Why is the ice shelf melting?

The Antarctic ice sheet is the world's largest permanently iced area. If the sea warms by only 0.5 degrees, the ice shelf melts from below and breaks at the edges.

What are viruses and how do they attack?

There are probably 100 million different types of viruses. Their attacks always follow the same pattern. The viruses attach to a cell, transfer their genetic material and force the host cells to produce new viruses. Author: 3sat/nano/Docstation/Johan von Mirbach/Anna Grün/Riccardo Giese/Nico Schleg

How does a fusion plant work?

Generating energy from the fusion of two atomic nuclei is a long-cherished dream of science. Researchers in Greifswald have come a lot closer to achieving it. The raw materials needed are found in water and rocks. Author: 3sat/nano/Vision Control/Juliane Helm/Thomas Thönnes/O-Sound source: Prof. Dr

Regional differences in sea-level rise

Sea level can deviate regionally from the global mean. Wind and currents push the water masses differently against the coasts and influence the level there. In addition, the earth's crust moves. Some coasts rise, others sink. Author: 3sat/nano/mobyDOK/Alexander Lahl/Max Mönch/Jean Schablin/Robert

What makes RNA viruses so dangerous?

The coronavirus is an RNA virus. An RNA is chemically more susceptible than a DNA. Errors occur more frequently during copying, and the virus mutates. Our immune system reacts slowly to it, vaccine development is more difficult. Author: 3sat/nano/Docstation/Johan von Mirbach/Anna Grün/Riccardo Gies

Melting ice in Greenland

Greenland's ice sheet consists of about 2.7 million gigatons of ice. Until 1990, the ice mass remained about the same. Since the turn of the millennium, Greenland has been steadily losing ice to the sea. Author: 3sat/nano/mobyDOK/Alexander Lahl/Max Mönch/Jean Schablin/Robert Coellen/Mirko Tribanek/

NOVA scienceNOW: How the Body Responds to Exercise

This video segment adapted from NOVA describes the effect of exercise on the body and defines one measure used to gauge aerobic fitness. VO2 max (maximal volume of oxygen uptake) is a measurement of how well the body gets and consumes the oxygen that muscles need in order to sustain activity. Learn

The Move of Homo Sapiens’ into Tropical Forests

For more Science Videos: https://lt.org/ * In popular culture as in traditional archaeology, the tropical forest has been assumed to represent an environment inhospitable to humans. In this video, PATRICK ROBERTS challenges this view, demonstrating not only that Homo sapiens moved into tropical fore

How To Practice Self Compassion

Self compassion, Self love, self care, self reflection - all of these are wonderful terms that are synonymous with maintaining your personal wellbeing! However, there are times where it can be difficult to take care of ourselves. We tend to blame ourselves for every little mistake, every little thin

Genetic Variance Through Sexual Selection

For more Science Videos: https://lt.org/ * How does sexual selection contribute to biodiversity on earth? ASTRID T. GROOT investigates this question using the example of moths. As she explains in this video, in many species, including moths, the most common individuals are chosen as mates and the on
