Smartphone users under age of 13 risk poor mental health when they are adults
Over 100,000 youngsters aged between 18 and 24, took part in a study, published Sunday in the Journal of Human Development and Capabilities.
The group were asked when they got a smartphone and a range of mental health symptoms,
The experts found that those who had a smartphone before age 13 had worse mental health and reported suicidal thoughts, as well as aggression.
As a result, experts at .Labs, which hosts the world's biggest database on mental health, have called for technology companies and parents to take "urgent" action and to roll out restrictions to stop under-13-year-old children from accessing smartphones.
Tara Thiagarajan, one of the study's authors, told ABC News: "The younger the child gets a smartphone, the more exposure to all this impacts them psychologically and shapes the way they think and view the world.
"Ideally, children should not have a smartphone until age 14, and when they do get a smartphone, parents should take the time to discuss with their children how to interact on the Internet and explain the consequences of doing various things.
"The longer we can push off allowing our kids to be on social media, we are learning, the better.
"I think lots of families are getting creative … landlines …. flip phones for kids [are] maybe an option so that they can have access to communicating without all the other things that come with smartphones."

Almost half our young Australians are lonely
Loneliness is not a word often associated with young people. We tend to think of our youth as a time spent with family, friends and being engaged with school and work activities. Loneliness is an experience we may be more likely to associate with older people. In a new report looking at loneliness in young Australians, we found 43 per cent of people aged 15 to 25 feel lonely. That's more than two in five young people. While one in four felt lonely when asked, one in seven had felt lonely for at least two years — what we call persistent loneliness. There's more we should be doing in Australia to address loneliness among young people and more broadly. What else did we find? In this report, we analysed data from the Household, Income and Labour Dynamics in Australia survey from 2022 to 2023. This helped us understand what sort of factors increase the risk of loneliness among young people. We found having poor physical health and mental health can double (or more) the likelihood of persistent loneliness among young people. Life circumstances, as well as socioeconomic and behavioural factors, also play a role, as shown below. Worryingly, young people who report persistent loneliness are over seven times more likely to experience high or very high psychological distress compared to those who aren't lonely. But loneliness in young people should not be seen just as a mental health issue. Research shows it can have consequences for physical health too. For example, a study published in 2024 found loneliness is linked to early signs of vascular dysfunction (functional changes to the arteries) in adults as young as 22. Why does loneliness persist? As well as analysing data, we also interviewed young people aged 16 to 25 from diverse backgrounds about what helps them make healthy social connections, and what hinders them. One of the things they flagged was a need for safe community spaces. A male participant from metro New South Wales, aged between 22 and 25, said: 'After lectures, someone's hungry, you go to eat together.' 'We used to go to (a restaurant) after almost every lecture. 'Talk or discuss some things so it gave us that extra opportunity to mingle amongst each other and take that next step towards building a good friendship.' We found technology could both help and hinder social connections. A female from regional Victoria, aged 22 to 25, who identified as LGBTIQ+, told us: 'If you're in school or something like that and you don't really have … many people within your community to look to, it's really nice being able to connect with people and make those friends online.' On the flip side, a female participant from metropolitan Victoria, aged between 16 and 18, said: 'A lot of maybe like mean stuff or like bullying and stuff happens over the Internet.' 'There's a big group chat and like everyone's texting on it or something. 'And then a lot of the time, people will break off into a smaller chat … or they'll break off into one on one and be like, ohh, do you see what she said?' The high cost of living was also regarded as a hindrance to maintaining social connections. As a male aged 22 to 25 from metro NSW told us: 'You'll go on (a) drive (with friends) or whatever … but that is so like incredibly expensive.' 'Having to pay for your own car and like petrol and insurance and maintenance. 'Sometimes it's hard to … even like … sit down in peace and have a chat. 'All the cafés will close at 2pm and by the time everyone gets out of their jobs, you're having to go to a restaurant and (you're) spending $50.' So what can we do? Loneliness has long been treated as a personal issue, but it's increasingly clear we have to shift our approach to include community-wide and systemic solutions. The World Health Organization's Commission on Social Connection recently released a report pointing to loneliness as a public health, social, community and economic issue. In Australia, the economic burden of loneliness stands at A$2.7 billion each year for associated health-care costs, including GP and hospital visits. And there are additional costs including lower workforce productivity and educational outcomes that have yet to be accounted for. Some countries have already developed and implemented strategies to address loneliness. In 2023, Denmark, for example, commissioned the development of a national loneliness action plan led by a consortium of organisations. This was underpinned by an investment of around 21 million Danish kroner (roughly A$5 million) over 2023–25. Australia now stands at a crossroads. Australia needs a national loneliness strategy A national strategy underpinned by evidence and by lived experience is crucial to effectively address loneliness. This approach would: coordinate efforts across sectors: health, education, social services and business identify effective strategies that should be included in a comprehensive response, and the principles to guide their delivery in communities and other settings highlight sub-groups at risk of persistent loneliness who should be prioritised within population-wide strategies commit to the delivery of a national awareness campaign that can educate the public and reduce stigma around loneliness. With the right national strategy, we will be able to increase our capacity to help all Australians, not just young people, connect in meaningful ways.

Smartphone users under age of 13 risk poor mental health when they are adults

As South Australia deals with its algal bloom, California is dealing with another
A dead sea lion is discovered on one end of the coast, and not far away an entire pod of long-beaked common dolphins lay stranded. It is becoming a familiar scene for those living along the coast of Southern California. And much like in South Australia, where thousands of dead sea creatures have washed ashore since March, a harmful algal bloom is to blame. Warning: This story contains content that some readers may find distressing. In California, this is the fourth consecutive year of death and destruction along the coastline. There have been scores of marine mammals and sea birds injured and killed, with US rescuers dealing with "by far historically the largest mass stranding event" relating to algal blooms. In South Australia, the Karenia mikimotoi bloom, kills fish and other sea creatures by impacting their gills, causing them to drown. In the US, authorities have been dealing with different types of algae, including one that produces domoic acid which can cause mammals like sea lions to experience seizures, behave aggressively or die. The Pacific Marine Mammal Center (PMMC) said the harmful algal bloom on the Southern California coast had significantly impacted sea lion and common dolphin populations and had killed two humpback whales and a minke whale. "In 2025, we've experienced the worst domoic acid algae bloom that we've ever experienced in Southern California history," Alissa Deming, PMMC vice president of Conservation, Medicine and Science told ABC News. Dr Deming said the PMMC hospital had taken in hundreds of sick mammals, which had been "physically demanding and very emotionally taxing" on staff and volunteers trying to help while protecting the public from aggressive animals. "A number of the sea lions were also pregnant, and that resulted in reproductive losses of over 85 fetuses born and lost in our hospital as a result of this bloom," she said. The veterinarian said there were likely similar drivers for its bloom to the one happening in South Australia including increasing marine temperatures and more nutrients from cold water upwelling. "By combining the warm sea surface temperatures with increased nutrients, that has resulted in us having a bloom event every year since 2022, with them seemingly becoming larger, longer lasting and covering a lot larger geographic region," Dr Deming said. Investigations are underway if the destructive Los Angeles wildfires in January and the associated run-off have contributed to the bloom. The US National Office for Harmful Algal Blooms said a conservative estimated cost of harmful algal blooms for the the US was about $50 million, but experts say expenses are hard to quantify. A 2024 study estimated losses to tourism-related businesses during the 2018 Florida red tide bloom at $US2.7 billion. Dr Deming said the US government agencies continued to have monitoring and management practices in place to support the commercial seafood industry. "Being able to have good federal and state agencies that can do surveillance to test to ensure seafood is safe for the public, as well as trying to come up with preventative measures or best management practices to prevent blooms, … are really high priority items," she said. "We're happy we have some of those systems in place, but there's absolutely room for improvement I think all around the world to help prevent the conditions that support these really long lasting and devastating blooms." Other algal blooms have also wreaked havoc in other parts of the world. An algae surge choked to death an estimated 40,000 tonnes of salmon in Chile in 2016 while hundreds of elephant deaths in Botswana in 2020 were linked to cyanobacteria, often called blue-green algae in Australia. The scale of each harmful algal bloom event seems to be increasing, professor Gretta Pecl from the University of Tasmania's Institute for Marine and Antarctic Studies told the ABC. "If there isn't something done to mitigate, to reduce climate emissions, warming will continue and these kinds of events will be more and more likely," she said. US research biologist at NOAA Fisheries Kathi Lefebvre, who has been studying harmful algal blooms for 25 years, said the blooms were getting worse and reaching areas "where we used to not have problems". "It is turning out to be a major impact of climate change." Authorities in South Australia have linked South Australia's algal bloom to climate change, and state and federal governments have pledged a collective $28 million for a suite of measures to tackle the algal bloom, including more funding for testing. Dr Lefebvre said authorities needed to take action now to mitigate the effects of future blooms. "What's going to happen if these blooms are going to be continuing is that there's going to need to be ways to test for toxins … to protect human health," Dr Lefebvre said. "The more information we have, the better decisions we can make.
