Revealing the secret life of a hedgehog
Hedgehog species are listed as being threatened throughout Europe. Here, a small hedgehog appears from the bushes. Credit: BeateStrøm Johansen In recent years, the hedgehog population has been decreasing. In 2021, they were placed on the Red List. Hedgehogs are endangered species in Norway and several other European countries. “We were surprised that hedgehogs did not retreat into the forest,…

New Leases in Life: Turn BioWaste into a valuable resource
Credit: Unsplash/CC0 Public Domain Central Macedonia, a region in the northern part of Greece, is a key producer of food. It produces a quarter of the country’s agricultural production and is a source of many Greek table olives, peaches, wine and dairy products. However, this productivity results in large amounts of agricultural waste. EU researchers now investigate how and how…

Sulfur may be a new tool to find alien life
A cartoon depiction of the sulfur cycles in various planetary regimes. In the case of Earth (a), the atmosphere so2 is scrubed from the atmosphere due to wet deposition. For example, in cases like Venus with UV irradiation (B), SO2 is abundant in deep atmosphere, such as by the sun. However, in the upper atmosphere, SO2 is efficiently catalyzed by…

Enzymes are the engine of life. Machine learning helps scientists design new things
The induction FIT model of enzymes states that both enzymes and their substrates change shape when they interact. Credit: OpenStax, CC BY-SA Enzymes are molecular machines that carry out chemical reactions that sustain all life, and are the ability to attract the attention of scientists like me. Consider the movement of your muscles. Your body releases a molecule called acetylcholine,…

Efforts to find an alien life can be boosted by simple tests that drive microorganisms
Credit: Pixabay/CC0 Public Domain Finding life in space is one of the great efforts of humanity. One approach is to find motile microorganisms that can move independently. This is an ability that is a strong hint in life. When movement is induced by a chemical and the organism moves accordingly, it is known as chemotactic. Currently, German researchers are developing…
