Killer whales seen ‘kissing' for the first time in the wild, photo shows
For the first time, a pair of killer whales were seen 'kissing' in the wild, photo and video evidence reveals.
The intimate encounter took place in October 2024, near the Kvænangen fjords of Norway, located above the Arctic Circle in the country's far north.
A group of snorkelers witnessed the 'rare and previously undocumented' encounter below their boat, according to a study published June 11 in the journal Oceans. One snorkeler captured video of it with a handheld GoPro camera.
The footage, available online, shows the two marine mammals touching mouths while floating motionless below the waves.
The amorous affair 'lasted nearly two minutes and involved repeated episodes of gentle, face-to-face oral contact,' according to the study, published by researchers from Spain and the Netherlands.
At the time of the observation, onlookers said the orcas 'appeared to be 'kissing' beneath the boat.'
While it's the first time such behavior has been recorded in 'free-ranging' or wild orcas, it has been documented in captivity on a few occasions.
For example, in 2013, a pair of killer whales in Loro Parque, a Spanish zoo, were seen engaging in tongue-to-tongue contact.
The behavior, dubbed 'tongue-nibbling,' has also been observed in other species under the care of humans, including in beluga whales at a SeaWorld in Texas. In most instances, it takes place between younger individuals.
Researchers described the curious conduct as 'a socially affiliative behavior' that is 'likely involved in reinforcing social bonds, particularly among juveniles.'
The fact that it has been documented across time and geographical settings 'suggests remarkable behavioural continuity,' they added.

Bacteria can turn plastic waste into a painkiller
When you buy through links on our articles, Future and its syndication partners may earn a commission. Tylenol could potentially be made greener and cheaper with the help of bacteria. Scientists were able to use a bacterial chemical reaction to convert a plastic water bottle into paracetamol with no environmental strain. This development could alter the way drugs are produced and provide a much-needed solution to the plastic pollution problem. The bacteria Escherichia coli or common in the gut microbiome, can be used to break down plastic into paracetamol, according to a study published in the journal Nature Chemistry. Paracetamol, or acetaminophen, is the main active ingredient in the painkiller Tylenol. It is generally produced using fossil fuels, namely crude oil, which has been known to worsen climate change. But "by merging chemistry and biology in this way for the first time, we can make paracetamol more sustainably and clean up plastic waste from the environment at the same time," said Stephen Wallace, a professor at the University of Edinburgh and the lead author of the study, to The Guardian. The researchers triggered a chemical reaction in known as the Lossen rearrangement that "until now had only been observed in test tubes," said Spanish newspaper El País. The was genetically modified to be able to break down polyethylene terephthalate (PET), a plastic used in food packaging and bottles, and ultimately produce paracetamol. This process can occur at room temperature and produces no carbon emissions. "It enables, for the first time, a pathway from plastic waste to paracetamol, which is not possible using biology alone, and it's not possible using chemistry alone," Wallace said to Science News. While it will take time before the painkiller can be widely produced using this method, "this could mark part of a broader shift toward more sustainable, biology-based manufacturing practices, both in the pharmaceutical industry and in plastic recycling," El País said. Plastic waste has been known to harm the environment and can pollute waterways and leach chemicals into the ecosystem. Microplastics have also been found almost everywhere on Earth and in our bodies. "I genuinely think this is quite an exciting sort of starting point for plastic waste upcycling," Wallace said. PET plastic "creates more than 350 million tons of waste annually," said a news release about the study. While PET recycling is possible, "existing processes create products that continue to contribute to plastic pollution worldwide." This research could be the solution to the pollution. The study's findings indicate that "PET plastic isn't just waste or a material destined to become more plastic," Wallace said in the release. "It can be transformed by microorganisms into valuable new products, including those with potential for treating disease." This is not the first time bacteria have been used to break down plastic, and it likely will not be the last. However, the ability to create medicine from plastic introduces a fresh area of research. "Based on what we've seen, it's highly likely that many — or even most — bacteria can perform these kinds of transmutations," Wallace said. "This opens up a whole new way of thinking about how we might use microbes as tiny chemical factories."

AI tools are helping teachers with grading and lessons
For her 6th grade honors class, math teacher Ana Sepúlveda wanted to make geometry fun. She figured her students 'who live and breathe soccer' would be interested to learn how mathematical concepts apply to the sport. She asked ChatGPT for help. Within seconds, the chatbot delivered a five-page lesson plan, even offering a theme: 'Geometry is everywhere in soccer — on the field, in the ball, and even in the design of stadiums!' It explained the place of shapes and angles on a soccer field. It suggested classroom conversation starters: Why are those shapes important to the game? It proposed a project for students to design their own soccer field or stadium using rulers and protractors. 'Using AI has been a game changer for me,' said Sepúlveda, who teaches at a dual language school in Dallas and has ChatGPT translate everything into Spanish. 'It's helping me with lesson planning, communicating with parents and increasing student engagement.' Across the country, artificial intelligence tools are changing the teaching profession as educators use them to help write quizzes and worksheets, design lessons, assist with grading and reduce paperwork. By freeing up their time, many say the technology has made them better at their jobs. A poll released Wednesday by Gallup and the Walton Family Foundation found 6 in 10 U.S. teachers working in K-12 public schools used AI tools for their work over the past school year, with heavier use among high school educators and early-career teachers. It surveyed more than 2,000 teachers nationwide in April. Respondents who use AI tools weekly estimate they save them about six hours a week, suggesting the technology could help alleviate teacher burnout, said Gallup research consultant Andrea Malek Ash, who authored the report. As schools navigate concerns over student abuse of the technology, some are also are introducing guidelines and training for educators so teachers are aware of avoiding shortcuts that shortchange students. About two dozen states have state-level AI guidance for schools, but the extent to which it is applied by schools and teachers is uneven, says Maya Israel, an associate professor of educational technology and computer science education at the University of Florida. 'We want to make sure that AI isn't replacing the judgment of a teacher,' Israel said. If teachers are using chatbots for grading they should be aware the tools are good for 'low-level' grading like multiple choice tests but less effective when nuance is required. There should be a way for students to alert teachers if the grading is too harsh or inconsistent, and the final grading decision needs to remain with the educator, she said. About 8 in 10 teachers who use AI tools say it saves them time on work tasks like making worksheets, assessments, quizzes or on administrative work. And about 6 in 10 teachers who use AI tools said they are improving the quality of their work when it comes to modifying student materials, or giving student feedback. 'AI has transformed how I teach. It's also transformed my weekends and given me a better work-life balance,' said Mary McCarthy, a high school social studies teacher in the Houston area who has used AI tools for help with lesson plans and other tasks. McCarthy said training she received from her school district on AI tools has helped her model proper use for her students. 'If I'm on the soapbox of, 'AI is bad and kids are going to get dumb,' well yeah if we don't teach them how to use the tool,' said McCarthy. 'It feels like my responsibility as the adult in the room to help them figure out how to navigate this future.' Views on the role of artificial intelligence in education have shifted dramatically since ChatGPT launched in late 2022. Schools around the country initially banned it, but since then many have sought ways to incorporate it into classrooms. Concerns about student overuse and misuse are still prevalent: About half of teachers worry that student use of AI will decrease teens' ability to think critically and independently or to have persistence when problem solving, according to the study. One benefit teachers see in becoming more familiar with artificial intelligence is the ability to spot when students are overusing it. Clues that assignments are written by AI tools include an absence of grammatical errors and complex phrases in writing, said Colorado high school English teacher Darren Barkett. He said he relies on ChatGPT himself to create lesson plans and grade multiple choice tests and essays. In suburban Chicago, middle school art teacher Lindsay Johnson said she uses only AI programs vetted by her school and deemed safe to use with minors, for data privacy and other concerns. To ensure students feel confident in their skills, she said she brings the technology in only for later stages of projects. For her 8th graders' final assessment, Johnson asked them to make a portrait of an influential person in their lives. After students put final touches on their subject's face, Johnson introduced generative AI for those who wanted help designing the background. She used an AI tool within Canva, after checking with her district's IT department that the design software passed its privacy screener. 'As an art teacher my goal is to let them know the different tools that are out there and to teach them how those tools work,' she said. Some students weren't interested in the help. 'Half the class said, 'I've got a vision, and am going to keep going with it.''
