An orcas diet consists of Chinook salmon and can eat up to two dozen fish a day - so why is it that the killer whales like to bully porpoises despite them not being part of their diet? That's the question which has left scientists scratching their heads, as the study published in Marine Mammal Science seeks to add further understanding to this subject. Around 78 cases of orcas targeting porpoises were noted by researchers from the UK, USA and Canada. It was said to be happening in the Salish Sea (located in the Canadian province of British Columbia and the U.S. state of Washington). Some of the orcas' bullying tactics include pushing the porpoise along with their nose, holding the porpoise in their mouth, balancing the porpoise above water, slapping the porpoise with their tail, and raking the porpoise with their teeth, according to Science Alert. Killer whales also use porpoises as playthings as they catch them before letting them and proceeding to chase them once more - and they even play toss them around in a 'pass the porpoise' game, say whale watchers. That's some textbook tormenting. Out of these sightings, 28 of them have ended in the harbour porpoise (Phocoena phocoena) or a Dall's porpoise being suspected to have been killed, though there's no record of the porpoises being eaten by the orcas. In terms of size, the porpoise is said to be fairly small being a similar size to a Chinook salmon - a large fish species that can grow up to 1.5 meters (5 feet). There are three theories that have been considered by the experts. Firstly, the bullying is all about creating coordination, and cohesion within the group of orcas, or alternatively that the orcas do this as a form of hunting practice. The final theory is that orcas could be trying to look after weak porpoises as if they were their own aka 'displaced epimeletic behaviour.' This mismothering behaviour – also known as 'displaced epimeletic behaviour' to scientists – might be due to their limited opportunities to look after youngsters as the stat shows. "Our research has shown that due to malnutrition, nearly 70 per cent of Southern Resident killer whale pregnancies have resulted in miscarriages or calves that died right away after birth." It seems that orcas are not the only bullies of the seas, as smaller dolphins e.g. bottlenose have similarly been seen harassing and killing for no clear reason.

Artificial intelligence (AI) could reshape jobs or be used to create conspiracy theories that could cause political instability, according to a document outlining the possible threats facing Ireland. The National Risk Assessment report, which began in 2014, aims to outline economic, security or political risks to Ireland in the coming years, with the aim of informing decisions and to prepare for those possibilities. It also aims to guard against “group think”, and states that it highlighted the risk of Brexit in its 2014 report, and the housing challenge in its 2015 report. In the introduction to the report, Taoiseach Leo Varadkar said the list of 25 risks range from climate change to newer risks such as the security of Ireland’s energy supply and the proliferation of disruptive technology like AI. The report stated that as disruptive technology trends develop, “these advances create a range of opportunities” but also pose a possibility for malign use. Coastal erosion, which can impact upon infrastructure and human settlement, will accelerate in the coming years National Risk Assessment report It said that disruptive technologies such as AI could cause automation that could “displace or reshape” jobs and sectors, or be used for “malign” purposes. “Generative AI systems, which make the rapid production of content based on a variety of source material (text, moving or still images, computer code) easily available to the public, will bring extraordinary change, but will also pose a challenge for societal resilience, in particular how we counter the harms that could flow from their malicious use. “This could include the use of AI to generate disinformation and misinformation, deepfakes, or conspiracy theories, with the potential to distort markets, undermine cohesion or cause political instability.” It added: “The spread of mis/disinformation, including via social media and other digital platforms, has the potential to undermine the State, the integrity of elections, social cohesion, and the functioning of the economy.” In relation to Northern Ireland, the report said that certain groups with “very limited levels of support” are “intent on disrupting the significant progress” to bring about peace on the island of Ireland. “The risks to Ireland posed by armed conflict, terrorism and hybrid security threats are potentially compounded by our having one of the lowest levels of investment in military and defence capabilities within Europe,” it said. The assessment also stated that Ireland’s housing shortage and pricing issues “are unlikely to rectify themselves over the short term”, with inflation and skilled labour shortages impacting supply. It said that high rent costs create a risk of a “locked-out generation”, and is impacting on homelessness, which is at record high monthly rates. “The housing challenge risks increasing social exclusion and impairing labour mobility,” it said, adding that the growing number of asylum seekers highlighted the “undersupply of appropriate housing and the inflexibility of the sector”. It highlights that climate change is happening at “an accelerating and alarming rate”, and that Ireland needs to urgently “step up” efforts to mitigate greenhouse gas emissions across all sectors of the economy. “…Failure to meet obligations and targets on emissions, energy usage, and renewable energy, set both by the EU and in national legislation, is a risk. “Inertia and resistance to change risks Ireland’s efforts at adaptation and mitigation.” It also highlighted extreme weather events in Ireland such as flooding and extreme temperatures, which have “major” impacts on the environment, people and economy. “Coastal erosion, which can impact upon infrastructure and human settlement, will accelerate in the coming years,” it said. “In this regard, it is notable that much critical infrastructure, such as power stations, wastewater treatment plants, and rail infrastructure can be found along our coastline. “Very significant investment, with associated delivery risks, will be necessary to build climate resilience into flood defences and water management systems, in order to secure communities and the infrastructure they depend on.” The assessment added: “Trade-offs and public expenditure choices will be required.” It also warned that vulnerabilities in global financial markets “have grown more pressing” and highlighted “a wide range of financial vulnerabilities and elevated uncertainty”. It said that Ireland’s post-Brexit relationship with Great Britain “will continue to present challenges”, particularly on trade as the UK moves to introduce checks and controls on imports. It warned that while Ireland is “a strong supporter” of EU enlargement it also poses a risk to cohesion across the bloc and may lead to changes in how the EU operates. The report said that the most extreme risks to Ireland “are outside exclusive national control”, and as a result, international relations, such as Ireland’s EU membership, are important. The development of the National Risk Assessment is overseen by a group of departmental officials and members of relevant agencies, chaired by the Department of the Taoiseach. A proposed list of strategic risks is drafted which is then published for public consultation, which took place from December 7 2022 to February 17 2023. The proposed risks are then reviewed and further considered by Government departments and agencies, and the final draft was considered by government on July 25.

WhatsApp is developing a range of new features, including a new username system and a screen-sharing option during video calls. The username system will allow users to select a unique name attached to their account, WABetaInfo first reported, based on changes spotted in the app’s beta version 2.23.11.15 for Android. This may enable users to find each other through usernames instead of phone numbers in the future, with conversations using the username expected to be end-to-end encrypted. Beta testers of the app’s 2.23.11.19 version also found a new screen-sharing feature that reportedly enabled users to share the contents of their screen on video calls, also allowing people to record sections of the call. Some testers also reported finding a “status archive” feature, limited to business accounts, which enables users to archive their WhatsApp statuses after 24 hours and reshare them later in the future. These features appear to be under development and not yet available to all testers. They may be gradually rolled out to users. Other changes include a new “password reminder feature” for end-to-end encrypted backups on WhatsApp for iOS and Android as well as an improved support for message drafts. The latter is expected to help users who may forget about partially composed messages in the middle of conversations. The Meta-owned company previously did not indicate the presence of a message under drafts in the chat bar and the new indicator of unfinished messages at the top of the chat list may allow users to notice this. Some users may notice a few small changes in WhatsApp’s bottom navigation bar on downloading the beta for Android 2.23.11.19 update. A new icon and a prompt during video calls seem to help users share their screen. The feature records everything displayed on one’s screen and shares it with the recipient. But the recipient may be unable to get the content of the sharer’s screen in case they are using an outdated WhatsApp version. Potential wider accessibility of this feature, however, remains unclear as it may not work in large group calls.
