Scientists at the University of Nottingham, in the United Kingdom, believe that the worm 'Caenorhabditis elegans', which has certain biological similarities with humans, could be the first to travel to other planets such as Mars to help us understand how we would manage an interplanetary journey.
The typical spider web has a unique evolutionary origin, according to research published by the journal Proceedings of the Royal Society. The work, in which Professor Miquel A. Arnedo, from the Department of Animal Biology and the Biodiversity Research Institute (IRBio) of the University of Barcelona participates, proposes the hypothesis that the diversification of cobwebs is a process that it responds to the need to occupy new natural habitats (trunks, stems, etc.) and to exploit resources in a more efficient way.
A team of researchers from Brown University (USA) has discovered a much faster way to tan the skin than exposing yourself to the sun for several days, according to a new study published in the specialized journal 'Current Biology'.
The mere presence of a predator can cause a dragonfly enough stress to literally starve to death, Canadian biologists have found, publishing their findings in the journal Ecology. "How prey respond to fear of being eaten is an important issue in ecology," explains Locke Rowe, co-author of the work.
On the coast of Las Cruces, in Chile, scientists have found the largest virus discovered so far. It is called 'Megavirus chilensis' and measures around 0.7 microns in diameter, which implies that it is 10 to 20 times larger than the average virus, and larger than some bacteria.
Some male crickets protect the lives of their mating partners, risking their own. Specifically, when a danger looms, the males let the "ladies" enter the burrow first, even though this implies an increased risk of being eaten. These conclusions have been reached by a group of scientists from the United Kingdom thanks to infrared video footage of a wild population of field crickets.
The personality of the fish can determine how they are caught by fishermen, according to a study by the Biological Station of Queen's University, in Australia. Those fishing near rocky areas or in areas of water with underwater vegetation will catch more timid fish, while anglers who go out to sea will catch the most daring.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
