Female frogs fake their own deaths to avoid sex with overzealous males
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 discover signs of water and carbon on asteroid sample
NASA has lifted the lid on its first findings about the Bennu sample, one of the "most hazardous known asteroids". The highly-anticipated sample from the OSIRIS-REx’s mission took seven years to complete and finally made a safe landing on Sunday 24 September. Scientists audibly gasped upon opening the capsule. They kept details to a minimum and maintained a slow pace in progress for "good reason," as they received more material than expected. "The abundance of material found when the science canister lid was removed earlier this week has meant that the process of disassembling the TAGSAM (Touch-and-Go Sample Acquisition Mechanism) head – which holds the bulk of material from the asteroid – is off to a methodical start," they said a the time. That was until now... On Wednesday 11 October, the space agency shared details for the first time from NASA experts and the University of Arizona. NASA said there were signs of water and carbon on the sample through hydrated clay minerals that contain carbon. "At nearly 5% carbon by weight, carbon being the central element of life, far exceeding our goal of 60g, this is the biggest carbon-rich asteroid sample ever returned to earth," Administrator Bill Nelson said, adding that it was "exactly the kind of material that we wanted to find." He went on to suggest that "they are going to help us determine the origin of elements that could have led to life" and provide a greater understanding of how to protect Earth from asteroids. Scientists also revealed that the sample contained space dust from 4.5-billion-year-old asteroid Bennu. NASA showed the audience the sample on a video to protect the sample and to prevent contamination. Speaking about working through a glove box to analyse the sample, Francis McCubbin, astronomical curator at NASA's Johnson Space Centre said: "[It is] "hard, challenging work, and it does not go quickly, but we need to do this right". The samples will be preserved so that "scientists that aren't even born yet are going to have the opportunity to answer questions about our universe with these samples using technology that has not even been invented."
