For the first time, an orangutan was observed and documented who used the leaves of a plant to heal a wound by applying certain substances directly to the lesion:this is the case of Rakus, a Sumatran orangutan who was caught while applying chewed plant residues with antibacterial and anti-inflammatory properties directly to the face, probably scarred during a clash with a rival.This is reported by the analyzes included in a peer-reviewed study published on Scientific Reports Of Nature.The research team, in 21 years of observations in the Gunung Leuser national park in Indonesia, had never seen other specimens self-medicating using this plant:"As far as we know, this is the first documented case of active wound treatment with a plant species with medical properties by a wild animal,” said senior study author Caroline Schuppli, an evolutionary biologist at the Max Planck Institute of Animal Behavior. The observations, as reported by research, began in 1994 and took place in th...

After a few days come on findings carried out in Chile, a new breath of fresh air for biodiversity has arrived from New Zealand:a three-week expedition of 21 scientists led to the discovery of hundreds of potential new marine species in the waters of Bounty trough, a vast, little-explored underwater bathymetric depression located off the east coast of the South Island.There are at least dozens of molluscs, three fish, a shrimp and a cephalopod never seen before and according to Alex Rogers, the marine biologist leading the expedition, the number of new species could exceed the hundreds when the results - almost 1,800 samples – will be confirmed.The mission was led by Ocean Census, a non-profit organization dedicated to the global discovery of ocean life, the National Institute of Water and Atmospheric Research (NIWA) and the Museum of New Zealand Te Papa Tongarewa.The Dr.Rogers explained that expeditions like the one just concluded are fundamental because allow us to obtain more...

There are deep-sea corals that could be at least a thousand years old, sponges, sea urchins, amphipods and lobsters:on seamounts located off the coast of Chile More than 100 potential new species have been discovered that could be unique in the world.The credit goes to an international team of researchers who, led by Javier Sellanes, full professor of Marine Sciences at the Universidad Católica del Norte, created breathtaking photos and videos that already seem destined to pique the attention of scientists in the coming months.The team explored seamounts along the Nazca and Salas y Gómez ridges with the aim of collecting data that could support future protected area designation and the Juan Fernández and Nazca-Desventuradas marine parks.A robot capable of descending to a depth of 4,500 meters was used to collect data from 10 mountains located below sea level, discovering that each “hosted diverse ecosystems, many of them vulnerable, including thriving deep-se...

They do not date back to the last thousands of years as previously thought, but to around 8,200 years ago:Within the already-attented archaeological site Cueva Huenul 1, in the desolate Patagonian desert, a cave with nearly 900 paintings has forced scientists to significantly revise their estimates.Among the most mysterious reasons A comb pattern that first appeared over 8 thousand years ago has been discovered, which thus becomes the oldest cave painting in Patagonia and among the most primitive ever found in South America.According to experts, cave artists continued to draw the same image for thousands of years with the aim of "passing down precious lessons" during a time when climate change threatened their survival.The research results were included in a study already subjected to peer review and published in the journal Science.«We got the results and we were very surprised. It was a shock and we had to rethink some things, commented Guadalupe Romero Villanueva, au...
