Scientists have experimentally demonstrated that kangaroos, wallabies and other Australian marsupials most fear the human ‘super predator,’ fleeing humans 2.4 times more often than any other predator. The post Australian Marsupials Fear Humans Far More Than Any Other Predator, New Study Shows appeared first on Sci.News: Breaking Science News. Scientists have experimentally demonstrated that kangaroos,…
A 3,500-year-old suit of Mycenaean bronze armor from the Greek village of Dendra may have been used in battle, not just for ceremonial purposes as previously thought. The post Ancient Mycenaean Armor Was Suitable for Extended Combat, Research Confirms appeared first on Sci.News: Breaking Science News. A 3,500-year-old suit of Mycenaean bronze armor from the…
In the first successful attempt to calibrate walrus counts from satellite imagery, scientists used drones to validate animal counts in Svalbard, Norway. On this International Day for Biological Diversity, the researchers describe how this study is a big step towards using satellite imagery as a non-invasive method to monitor walruses in the Arctic. In the first…
UPV/EHU researcher Irantzu Vergara has managed to simultaneously analyze several families of antibiotics in vegetables and earthworms. Sampling carried out in various locations of the Basque Autonomous Community has yielded data on the existence of antimicrobial agents and their derivatives in vegetables. Vergara stresses the need for further research to address the problem of contamination…
In a behavioral experiment, crows were able to learn to produce a set number of calls. This involves them planning in advance. From the sound of the first call in a numerical sequence, it is possible to predict how many calls the crows will make. A research team consisting of Dr. Diana A. Liao, Dr….
In organic chemistry, π-stacking systems are supramolecular structures that arise due to the dispersion force, a type of intermolecular noncovalent interaction. They are a common occurrence in nature. The stabilized structure of DNA is a very prominent example of a π-stacking system, and so are the arrangement of amino acids in certain proteins. In organic chemistry,…
