Ticks – the dreaded summer bogeymen can transmit a variety of diseases

Ticks – the dreaded summer bogeymen can transmit a variety of diseases

24. Aug. 2016 • Biologické vedy

Ticks haunt us specifically during the summer. The less we know about them, the more we fear them. We stress about ticks during the holidays on our trips to the countryside. We buy and use repellents, monitor milk products – ticks present a problem for us. They inhabit places with grass – forest fields, forest trails and damp valleys, but they are also getting into cities. These parasitic Read more

The Circulatory System’s blood vessels could stretch around our Earth’s equator twice

The Circulatory System’s blood vessels could stretch around our Earth’s equator twice

01. Mar. 2016 • Biologické vedy

Did you know that the blood vessels in a single human body could get around our earth’s equator two times? Blood distributes substances necessary for a normal functioning of the human organism.  The organ that ensures that our blood keeps flowing is our heart, which pumps blood throughout our whole body. Our blood vessels are actually pipes full of blood. Various nutrients, such as oxygen or Read more

The human being is actually a bacterium

The human being is actually a bacterium

25. Sep. 2015 • Biologické vedy

Researchers found out that on the cellular level, the human being is actually a bacteria. (The Human Microbiome Project). When you say the word “bacteria”, most of us will imagine a disease, long waits at the doctor and antibiotics. It is interesting that a large part of the human’s body proper functioning is caused by “good” bacteria, which are more or less all over the body (from the Read more

Software operating a living cell

Software operating a living cell

18. Sep. 2015 • Biologické vedy

Did you know that scientists created the world’s first synthetic organism? One of the hot topics of biological research is the creation and existence of artificial life. Recently, scientists have tested new software that completely operates a living cell. They transplanted a computer “designed” and artificially synthesized genome into a bacterial cell. Without a single piece of natural DNA, Read more

When you have a “light bulb moment”

When you have a “light bulb moment”

01. Sep. 2015 • Biologické vedy

Did you know the brain is able to produce energy needed to light up a single bulb? (Maybe that’s why we experience “light bulb moments”) Read more

Fetal DNA in maternal blood

Fetal DNA in maternal blood

31. Aug. 2015 • Biologické vedy

Did you know that during pregnancy, fetal DNA is present in mother’s blood? It is possible to separate the DNA from a sample of the mother’s blood and find out many things about the baby’s genes. Read more

Accelerating bacterial growth

Accelerating bacterial growth

28. Aug. 2015 • Biologické vedy

Interestingly, bacterial growth can be accelerated even after 27 years and even if it is the 50 thousandth generation of bacteria. In 1988, Richard Lenski started a scientific experiment to examine the process of evolution. He inoculated 12 bacterial cultures. Every 24 hours, when the bacteria ran out of nutrients, he removed a part of the cultures and moved them to another test-tube with fresh Read more

The World’s Heaviest Cell

The World’s Heaviest Cell

21. Aug. 2015 • Biologické vedy

Would you ever think of an ostrich egg as the heaviest cell in the world? People think of the term “cell” as something complicated but also something very tiny that can only be viewed using a microscope.  However, this doesn’t apply to all cells – some are visible to the human eye. For example, if you peel an orange and divide it into carpels, you will end up with individual plant cells. Read more
