Experts have been left baffled after the body of a female orca (Orcinus orca) was found on a beach and inside there were seven sea otters that had been swallowed whole. The dead animal washed up on the Commander Islands (Komandorski Islands) on the Bering Sea coast in 2020 - far from its typical area, according to the study published in Aquatic Mammals. But there has been further confusion due to otters not being associated as part of an orca's normal diet, with the species preferring seals, sea lions, dolphins, and whales. Six of the seven otters were inside the orca's stomach while the other one was lodged in the orca's throat, raising a possible answer to how the mammal died. Dr Olga Filatova, a cetacean researcher at Moscow State University described what they had found as "very unusual" and noted that otters are not associated with an orca's - aka a killer whale's - diet. “...killer whales normally do not eat sea otters - there were some observations of them harassing and killing sea otters, but very few proofs of actual consumption," she said. What's more, the fact that the otters were swallowed whole is also different from how orcas typically consume their food as they normally rip it apart. Therefore, this particular orca swallowing seven otters whole has raised some eyebrows. Some possible theories Dr. Filatova has come up with as to understand what happened include the idea that the orca was "very hungry, or sick, or crazy". Meanwhile, this bizarre case could possibly be the answer to the recorded decline in sea otters in the area. “Investigating the stomachs of stranded killer whales is crucial to directly confirm feeding on particular species," Dr Filatova and her colleagues concluded.

Curly hair may have been absolutely critical to humans evolving millions of years ago, scientists have discovered. In fact, having curly hair could have been the key reason as to why humans developed, grew taller and came to have larger brains. It’s all to do with regulating body temperature, according to a new study by researchers at Penn State University. Given that hair can help to protect the head from the sun’s rays, it’s thought that thicker, curlier hair types could have been key to human life progressing in Equatorial Africa. Scientists recreated the kinds of conditions that early humans would have experienced, using wigs featuring different hair types on models. They found that curls were most effective in keeping the models cool in an environment measuring 86 degrees Fahrenheit (30 degrees Celsius) and 60 per cent humidity. Tina Lasisi is the study's lead author. She spoke to Newsweek about the findings and said: "We hypothesized that tightly curled scalp hair would provide some benefits, but the extent of these benefits was uncertain. "Previous studies on mammalian coats have shown that hair can limit the amount of sunlight reaching the skin, but we were particularly surprised by the significant reduction in solar heat radiation impact provided by tightly coiled hair.” The reduction in heat caused by tight curls could have led to the development of larger brains. "Once humans developed large brains, they could employ other behavioral and social strategies to cope with heat, potentially diminishing the relative advantage of curly hair," she said. "This could have led to a diverse distribution of hair textures worldwide. Furthermore, since straight hair better retains heat, populations in colder environments may have experienced selective pressure for straight hair." She added: "Future research should aim to answer these questions by incorporating our data into mathematical models of human physiology or conducting experiments with human subjects who have different hair textures to examine the impact on their thermal regulation.” Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Just when we think we’ve found the best first post on Threads, Instagram’s new “civil” text-based app to rival Twitter, another one comes along which is miles better – and former Labour MP Ed Balls may be the all-out winner after posting exactly what you would think he would post. Well-known for his 2011 Twitter blunder in which he tweeted out his own name instead of searching for it, the Good Morning Britain presenter and ex-shadow chancellor now marks the iconic moment every 28 April on ‘Ed Balls Day’. Sign up to our free Indy100 weekly newsletter Now, adhering to the politician’s principle of giving the people what they want, Mr Balls has set up an account on Threads and kicked things off by posting those two magic words. And it’s fair to say other users on the platform absolutely loved it. One declared: “You’ve won Threads today!” “Thread Balls,” quipped another. A third replied: “I think you win the internet today.” Others, though, have questioned what this means for marking the special occasion, seeing as the Twitter mishap occurred on 28 April (as mentioned previously), but this more deliberate posting happened on 6 July. “Ed! Now I need to rearrange my whole calendar for a new holiday,” complained one user. A second jokingly fumed: “Who do you think you are, Ed? The monarch? You don’t get two special days.” Another asked if the post marked “the new Ed Balls Day”, but that question remains unanswered. It’s unknown whether his wife Yvette Cooper MP, the shadow home secretary, will replicate the meme by reposting one of her Twitter typos. She does have a Threads account, at least… Have your say in our news democracy. Click the upvote icon at the top of the page to help raise this article through the indy100 rankings.

Google has announced that its apps and services will now be “passwordless by default” in an effort to make all users switch to passkeys. The move is part of a broader consensus among the tech industry to ditch passwords, which have been around since the 1960s, and switch to a safer and more efficient format to verify a person’s identity. Passkeys combine a code with biometric information like a fingerprint or facial recognition, making them easier to remember and harder to be stolen. Google apps like YouTube, Search and Maps all support the new format after it was first introduced earlier this year, though take up has been slower than expected. The tech giant said the push to get users to adopt passkeys coincided with Cybersecurity Awareness Month, claiming that the new technology is faster and more secure. “They are 40 per cent faster than passwords – and rely on a type of cryptography that makes them more secure,” Google product managers Sriram Karra and Christiaan Brand wrote in a blog post explaining the move. “We’ll continue encouraging the industry to make the pivot to passkeys – making passwords a rarity, and eventually obsolete.” Google users who do not already use passkeys will receive a prompt to set one up the next time they sign into their account. Passkeys have already been enabled by other online platforms, including eBay and Uber, as the tech industry looks to completely transition away from traditional passwords. “We’ve seen great results from launching passkeys across our apps and encourage all users to adopt passkeys,” said Ramsin Betyyousef, a senior director of engineering at Uber. “Ultimately this is a win-win for Uber and Uber’s customers.” Google, which counts billions of users across all of its platforms, acknowledged that “new technologies take time to catch on”, and have therefore given people the option to temporarily opt out of passkeys and use passwords wherever possible. The company did not set a date for when passwords will be phased out entirely, but some security experts contend that their death is inevitable while hackers continue to exploit their vulnerability. Helping implement the transition is the FIDO (Fast Identity Online) Alliance, which has been working with Apple, Google, Microsoft and hundreds of tech companies to develop the new login standard. “The complete shift to a passwordless world will begin with consumers making it a natural part of their lives,” said Alex Simons, who heads Microsof’s Identity Program Management team. “By working together as a community across platforms, we can at last achieve this vision and make significant progress toward eliminating passwords.” Read More Pixel 8: Google unveils ‘AI-centred’ iPhone rival Google to trial AI in UK traffic light systems to reduce stop-and-go emissions Pixel 8: Google unveils DeepMind-powered iPhone rival China’s discovery of never-before-seen ore could propel battery technology
