Female frogs fake their own deaths to avoid sex with overzealous males
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.

Netflix launches account and password sharing crackdown in US and UK
Netflix launches account and password sharing crackdown in US and UK
Netflix is launching its long-threatened password sharing crackdown in the UK. The company is writing to members who are sharing Netflix accounts and telling them that they will no longer be permitted to do so. Instead, they will be encouraged to “transfer a profile” so that users can have their own standalone accounts, or “buy an extra member”, which will let people who don’t live in a household be added for £4.99 a month. “Your Netflix account is for you and the people you live with – your household,” the email sent to problem accounts reads. The message will only be sent to those suspected of currently sharing their accounts. Netflix has not revealed exactly how it is tracking those it believes to be sharing passwords with people outside their households. But it says that it is watching for telling “account activity”, based on IP addresses and devices IDs, which might for instance indicate that an account is being used in two very different places at once. It stressed that the crackdown will not apply to those who are using their account for travelling. “You can easily watch Netflix on the go and when you travel – either on your personal devices or a TV at a hotel or holiday home,” the email reads. Users who are affected are encouraged to go to Netflix’s help centre. But the email also offers a variety of ways to deal with the problems. First, users are encouraged to “control how your account is used” by checking who is currently accessing their account. Netflix has a web page that will show what devices are currently logged into an account, and that same page can be used to kick them out of an account – after which the company encourages changing the password so that any old devices cannot log back in. If those people sharing an account are doing so with permission, however, Netflix is offering a variety of options. The transfer a profile tool will mean that users can set up a new, separate account but keep their watch history and other details, or the “buy an extra member” tool essentially lets someone outside the home have permission to share an account for less than the price of a full membership. Netflix has been gradually rolling out its password sharing crackdown across the world, beginning in Latin America and since expanding to other regions including Spain and Portugal. It has not said how it is deciding which countries are chosen to be hit by the new crackdown. The move is one of a range of changes from Netflix as it attempts to deal with slowing rates of subscriber growth that have led it to look for new ways to boost profitability. It has said that it believes some 100 million people around the world are using other people’s Netflix accounts – and that encouraging at least some of those to sign up could deal with those falling rates of signups. In its results call in April, Netflix said that early tests had shown that the crackdown was successful in encouraging people to sign up for their own accounts. While customers initially cancelled their accounts in response to the news, membership and revenue then rose after that as people started paying for their own logins, said co-chief executive Greg Peters. He also noted then that testing had revealed some problems with the crackdowns, including users complaining that they were being targeted when they were using the app on the go or while on holiday. Netflix had updated the technology underpinning the new rules in response to those complaints, he said – and it was those improvements that had given it confidence to launch the crackdown more broadly.

AI is using vast amounts of water
AI is using vast amounts of water
Artificial intelligence is using gallons upon gallons of water. Microsoft alone used more than 2,500 Olympic-sized swimming pools of water in its data centres last year. The latest numbers are leading to yet more questions about the sustainability and environmental dangers of the growth of artificial intelligence and related technology. Artificial intelligence requires vast computing resources, undertaking deeply complex calculations on behalf of people around the world. AI systems tend to be run in the cloud rather than on individual people’s computers, meaning that companies running them must operate vast server farms to deal with the queries of their users. Those server farms in turn need to pump in water to cool themselves down, because of the heat generated by those computers. That has long been a concern for environmentalists, but the sharp growth in artificial intelligence has led to even more use. Microsoft’s water consumption rose 34 per cent between 2021 and 2022, according to its latest environmental report, highlighted by the Associated Press. It was up to almost 1.7 billion gallons. Not all of that is from artificial intelligence. But Shaolei Ren, a researcher at the University of California, Riverside working to better understand the environmental impact of AI told the AP that the “majority of the growth” is because of the technology. Google also said that its water use had increased by 20 per cent over the same period. That varied across its different data centres, which are based in different parts of the US. For each 5 to 50 prompts, or questions, put to ChatGPT, it uses 500 millilitres of water, according to a paper that will be published by Professor Ren and his team later this year. Many technology companies have expressed concerns about their own water use, and how to minimise any negative effects of their data centres. The environmental concerns can be especially pressing because the use of water can be focused in particular areas around a data centre, meaning that the damage may not be spread. Google said last year for instance that “Wherever we use water, we are committed to doing so responsibly”. That includes analysing where water is being used and how much stress it might put on the surrounding area, for instance.
