Is there anywhere else in our solar system that could support life? An imposing NASA probe is due to lift off on Monday on a five-and-a-half-year journey to Europa, one of Jupiter's many moons, to take the first detailed step toward finding out.

The Europa Clipper mission will allow the US space agency to uncover new details about the moon, which scientists believe could hold an ocean of liquid water beneath its icy surface.

Liftoff is scheduled for "no earlier than" Monday, October 14, from Cape Canaveral in Florida aboard a powerful SpaceX Falcon Heavy rocket, NASA said in a statement.

"Europa is one of the most promising places to look for life beyond Earth," said NASA official Gina DiBraccio at a news conference last month.

The mission will not look directly for signs of life but will instead look to answer the question: Does Europa contain the ingredients that would allow life to be present?

If it does, another mission would then have to make the journey to try and detect it.

"It's a chance for us to explore not a world that might have been habitable billions of years ago," like Mars, Europa Clipper program scientist Curt Niebur told reporters last month, "but a world that might be habitable today, right now."

The probe is the largest ever designed by NASA for interplanetary exploration.

It is 30 meters wide when its immense solar panels -- designed to capture the weak light that reaches Jupiter -- are fully extended.

- Primitive life? -

While Europa's existence has been known since 1610, the first close-up images were taken by the Voyager probes in 1979, which revealed mysterious reddish lines crisscrossing its surface.

The next probe to reach Jupiter's icy moon was NASA's Galileo probe in the 1990s, which found it was highly likely that the moon was home to an ocean.

This time, the Europa Clipper probe will carry a host of sophisticated instruments, including cameras, a spectrograph, radar, and a magnetometer to measure its magnetic forces.

The mission will look to determine the structure and composition of Europa's icy surface, its depth, and even the salinity of its ocean, as well as the way the two interact -- to find out, for example, if water rises to the surface in places.

The aim is to understand whether the three ingredients necessary for life are present: water, energy and certain chemical compounds.

If these conditions exist on Europa, life could be found in the ocean in the form of primitive bacteria, explained Bonnie Buratti, the mission's deputy project scientist.

But the bacteria would likely be too deep for the Europa Clipper to see.

And what if Europa isn't habitable after all? "That also opens up a whole wealth of questions: Why did we think this? And why is it not there?" said Nikki Fox, an associate administrator at NASA.

- 49 flybys -

The probe will cover 2.9 billion kilometers (1.8 billion miles) during its journey to Jupiter, with arrival expected in April 2030.

The main mission will last another four years.

The probe will make 49 close flybys over Europa, coming as close as 25 kilometers (16 miles) above the surface.

It will be subjected to intense radiation -- the equivalent of several million chest x-rays on each pass.

Some 4,000 people have been working on the $5.2 billion mission for around a decade.

NASA says the investment is justified by the importance of the data that will be collected.

If our solar system turns out to be home to two habitable worlds (Europa and Earth), "think of what that means when you extend that result to the billions and billions of other solar systems in this galaxy," said Niebur, the Europa Clipper program scientist.

"Setting aside the 'Is there life?' question on Europa, just the habitability question in and of itself opens up a huge new paradigm for searching for life in the galaxy," he added.

The Europa Clipper will operate at the same time as the European Space Agency's (ESA) Juice probe, which will study two other moons of Jupiter -- Ganymede and Callisto.

A shark mauled a boy swimming in Sydney Harbor on Sunday, leaving him in critical condition with serious leg injuries, authorities said.

The predator bit the boy, believed to be about 13 years old, during the late afternoon off Shark Beach, New South Wales state police said.

"The injuries are consistent with what is believed to have been a large shark," police said in a statement.

Officers pulled the boy from the water off the harbor beach within minutes of being alerted to the incident, police said.

They gave the boy first aid for "serious" leg injuries while he was aboard a police boat, applying two medical tourniquets.

Paramedics transported him to Sydney Children's Hospital, where he was said to be in critical condition.

"Swimmers are advised to avoid entering nearby waters at this time," police said.

Shark Beach, in Sydney's eastern suburb of Vaucluse, was closed and police evacuated nearby beaches in the harbor, the state government said.

Wildlife experts were working to identify the shark species involved, it said in a statement.

"This is a tragic shark attack on a young boy having a swim on a Sunday afternoon near a harbor beach in Sydney's east," New South Wales Agriculture Minister Tara Moriarty said.

"Our thoughts are with the young boy and his family. I understand there were also other young people with him at the time of the attack, our thoughts are also with them."

There have been more than 1,280 shark incidents around Australia since 1791, of which more than 250 resulted in death, according to a database of the predators' encounters with humans.

Increasingly crowded waters and rising ocean temperatures that appear to be swaying sharks' migratory patterns may be contributing to a rise in attacks despite overfishing depleting some species, scientists say.

A great white shark mauled surfer Mercury Psillakis to death at a popular northern Sydney ocean beach in September.

Two months later, a bull shark killed a woman swimming off a remote beach north of Sydney.

It’s simple to accidentally become entranced by an endless loop of videos on Instagram or TikTok. But sometimes, that mindless scroll is interrupted by a reminder that what you thought was a 10-minute break spent on your phone was closer to 30 minutes.

Olivia Yokubonis, armed with a kind voice and scientific research, often pops up in feeds on social platforms, gently reminding viewers that they might not remember the video they saw two videos before she appeared on the screen.

Yokubonis is a content creator who goes by the name Olivia Unplugged online, making videos to combat overuse or mindless use of social media. For the most part, people who view her videos welcome the disruption from the endless loop of content, treating it as a wake-up call to get off their phones. Other times, they are snarky, The Associated Press said.

“People will comment and they’ll be like, ’Oh, (it’s) ironic that you’re posting. And I’m like, ‘Where else am I supposed to find you, Kyle? Outside? You’re not outside. You are here, sitting here,’” she said. “For us to actually be seen, we have to be where people are.”

Yokubonis’ content responds to the feeling many people have, that they spend too much time on social media or apps.

“Most people have no clue how much time they spend on social media,” said Ofir Turel, a professor of information systems management at the University of Melbourne who has been studying social media use for years. Through his research, Turel found that when he presented people with their screen time information, they were practically “in a state of shock” and many people voluntarily reduced their usage afterwards.

Yokubonis is part of a growing group of content creators who make videos encouraging viewers to close out the app they’re on. Some are aggressive in their approach, some more tame; some only occasionally post about social media overuse, and some, like Yokubonis, devote their accounts to it.

She works for Opal, a screen time app designed to help users “reclaim their focus,” she said, but those who engage with her content might not have any idea she is working for the company. Brand logos, constant plugs to download the app and other signs of branding are almost entirely absent from her page. “People love hearing from people,” she said. Millions of views on her videos point to that being true.

“It’s a fine line and a balance of finding a way to be able to cut through that noise but also not adding to the noise,” she added.

Ian A. Anderson, a postdoctoral scholar at California Institute of Technology, said he finds this kind of content interesting, but is curious whether it's disruptive enough to prompt action. He also said he wonders whether those with the strongest scrolling habits are “thoughtless about the way (they're) intaking information.”

“If they're paying full attention, I feel like it could be an effective disruption, but I also think there is a degree to which, if you are really a habitual scroller, maybe you aren’t fully engaging with it,” he said. “I can think of all sorts of different variables that could change the effectiveness, but it does sound like an interesting way to intervene from the inside.”

With billions of active users across TikTok, Instagram, YouTube and other social media platforms, talk of cutting down on screen time is perennial, as is the idea of addiction to social platforms. But there’s tremendous disagreement over whether social media addiction actually exists.

Is social media “addiction” real? Researchers, psychologists and other experts agree some people spend too much time on social media, but the agreement tends to stop there. Some researchers question whether addiction is the appropriate term to describe heavy use of social media, arguing that a person must be experiencing identifiable symptoms, like strong, sometimes uncontrollable urges and withdrawal, to qualify as addiction. Others, like Turel, acknowledge the term seems to resonate with more people and is often used colloquially.

Anderson said he recognized the prevalence of casual mentions of being addicted to phones and was curious to see if that talk was “benign.”

A recent study of his suggests the debate extends further than academic discourse. In a representative sample of active Instagram users, Anderson found that people often overestimate whether they are “addicted” to the app. On a self-report scale, 18% of participants agreed that they were at least somewhat addicted to Instagram and 5% indicated substantial agreement, but only 2% of participants were deemed at risk of addiction based on their symptoms. Believing you are addicted also impacts how you address that issue, Anderson said.

“If you perceive yourself as more addicted, it actually hurts your ability to control your use or your perception of that ability and makes you kind of blame yourself more for overuse,” Anderson said. “There are these negative consequences to addiction perception.”

Cutting down on screen time

For those looking to curb their social media habits, Anderson suggests making small, meaningful, changes to stop from opening your social media app of choice. Moving the app’s place on your phone or turning off notifications are “light touch interventions,” but more involved options, like not bringing your phone into the bedroom — or other places where you often use it — could also help.

Plenty of intervention methods have been offered to consumers in the form of products or services. But those interventions require self awareness and a desire to cut down on use. Content creators who infiltrate social media feeds with information about the psychology behind why people scroll for hours a day can plant those early seeds.

Cat Goetze, who goes by CatGPT online, makes “non-pretentious, non-patronizing” content about artificial intelligence, building off her experience in the tech industry. But she’s also been on a lengthy road to cut down her own screen time. She often makes videos about why the platforms are so compelling and why we tend to spend longer than we anticipate on them.

“There’s a whole infrastructure — there’s an army of nerds whose only job is to get you to increase your time spent on that platform,” she said. “There’s a whole machine that’s trying to get you to be that way and it’s not your fault and you’re not going to win this just (through) willpower.”

Goetze also founded the business Physical Phones, which makes Bluetooth landline phones that connect to smartphones, encouraging people to spend less time on their devices. The inside of the packaging reads “offline is the new luxury.”

She was able to build the business at an accelerated pace thanks to her social media audience. But the early success of Physical Phones also demonstrates the demand for solutions to high screen time, she said.

“Social media will always play a part in our lives. I don’t necessarily think that’s a bad thing. If we can get the average screen time down from, if it’s 10 hours for a person to one hour, or from three hours to 30 minutes, that is going to be a net positive benefit for that individual and for society,” Goetze said. “That being said, I’d love to be the person that they’re watching for those 30 minutes.”

A German man has been killed in an avalanche in the Swiss alps and four other people were hurt as they were cross-country skiing, Swiss police said Saturday.

The incident happened on Friday, on the Piz Badus peak near the village of Tujetsch in the center-south of the country, AFP reported.

Police said a group of seven cross-country skiers were swept up in the avalanche, with five of them buried underneath.

One member of the party raised the alarm in a phone call to local police, who deployed helicopters with rescue workers and dogs to the site.

The German man was found lifeless under the snow and ice, the police said, adding that the four others hurt -- whose nationalities were not given -- suffered light injuries and were flown to nearby hospitals.
