Some female frogs will go to the extent of faking their own deaths to avoid sex with their male counterparts, a new study has revealed. Researchers in Berlin and Finland focused on the European common frog for their investigation owing to the often alarming nature of the species' mating process. The short breeding season means that several males often cling to a single female – in a pile-on that can cause the female to drown. (So, pretty understandable that they might want to avoid this.) For the research published in the Royal Society Open Science, European common frogs were collected and divided into tanks where there were two females and one male in each. Before this research, it was thought that the females couldn't defend themselves against the aggressive amorous act. However, a number of the wily participants displayed the three avoidance behaviours. A rotation technique to escape mating was a popular option – carried out by 83 per cent of the females. While nearly half of them (48 per cent) mimicked how male frogs sound to trick them into letting them go. In 33 per cent of the females, the researchers recorded a stiffening of arms and legs for two minutes, in a convincing bid to play dead. Out of the females who got mounted by a lustful male, almost half were able to escape thanks to at least one of these avoidance behaviours. “The smaller females also showed the full repertoire of behaviours more often than the larger females," the researchers noted, and younger females were more likely to pretend they were dead. However, question marks remain on whether the frogs fake their death as a conscious choice or whether it is a stress response or even a means to test the male’s strength and endurance. “I think even if we call this species a common frog and think we know it well, there are still aspects we don’t know and perhaps haven’t thought about," Dittrich explained to The Guardian.

Nasa has revealed chunks of a distant asteroid that were transported back down to Earth. The dark, dusty sample comes from a 4.5-billion-year-old asteroid, and might include the “building blocks of life”, the space agency said. Already, the material from the asteroid Bennu has been found to include high-carbon content and water, the space agency said. But it will be distributed around the world with a view to finding out everything from the history of our solar system to how life came about. Scientists and space agency leaders showed photos and video of the asteroid material - returned to Earth last month - at a live streamed event at the Johnson Space Centre in Houston, Texas. The display came after a capsule containing an estimated 250g of rocks and dust collected from asteroid Bennu, touched down in the Utah desert near Salt Lake City on September 24. Nasa has said it was “the biggest, carbon-rich asteroid sample ever delivered to Earth”, and its contents have now been hailed as “scientific treasure”. Nasa administrator Bill Nelson said the sample will “help scientists investigate the origins of life on our own planet for generations to come”. He added: “Almost everything we do at Nasa seeks to answer questions about who we are and where we come from. “Nasa missions like Osiris-Rex will improve our understanding of asteroids that could threaten Earth while giving us a glimpse into what lies beyond. “The sample has made it back to Earth, but there is still so much science to come - science like we’ve never seen before.” Almost 60 million miles away, asteroid Bennu is a 4.5-billion-year-old remnant of our early solar system and scientists believe it can help shed light on how planets formed and evolved. The spacecraft launched on September 8 2016 and arrived at Bennu in December 2018. It dropped the samples off sealed in a capsule last month. “Already this is scientific treasure,” said the mission’s lead scientist, Professor Dante Lauretta, of the University of Arizona on Wednesday. In a statement, he added: “As we peer into the ancient secrets preserved within the dust and rocks of asteroid Bennu, we are unlocking a time capsule that offers us profound insights into the origins of our solar system. “The bounty of carbon-rich material and the abundant presence of water-bearing clay minerals are just the tip of the cosmic iceberg. “These discoveries, made possible through years of dedicated collaboration and cutting-edge science, propel us on a journey to understand not only our celestial neighbourhood but also the potential for life’s beginnings. “With each revelation from Bennu, we draw closer to unravelling the mysteries of our cosmic heritage.” Nasa‘s mission goal was to collect was 60 grams of asteroid sample. But when the canister lid was opened, Nasa said scientists discovered “bonus material” covering the outside of the collector head, canister lid, and base. There was so much extra material it slowed down the process of collecting and containing the primary sample, Nasa said. Scientists are not sure exactly how much of Bennu they brought back because the main sample chamber has not yet been opened. Mr Lauretta said: “It’s been going slow and meticulous, but the science is already starting.” He said there is “a whole treasure chest of extraterrestrial material” still to be examined. During Wednesday’s press conference, Osiris-Rex sample analyst Daniel Glavin added: “This stuff is an astrobiologist’s dream, I just can’t wait to get at it. “We’re going to learn so much about the origin of the solar system, the evolution and potentially how even life started here on Earth.” Additional reporting by agencies Read More ‘Ring of fire’ solar eclipse this month will be last until 2046 Prada to design Nasa’s next-gen space suits for Artemis astronauts 1.2 mile-high ‘dust devil’ spotted on Mars by Nasa’s Perseverance rover Rover captures one-mile-high whirlwind on Mars Earth hit by a huge solar storm that would devastate civilisation, trees show Scientists see afterglow from huge planets crashing into each other for first time
