This Sunday on 7News Spotlight Michael Usher asks whether major weight-loss drugs may be useful in addressing various other addictions,

It has already transformed the fight against obesity. Now, scientists believe popular weight-loss drugs like Ozempic, Wegovy and Mounjaro could be unlocking something even bigger.

More than half a million Australians are using GLP-1 medications, with remarkable results. And researchers are now investigating whether these drugs do more than switch off hunger – potentially helping to silence some of the brain's most powerful addictions.

In this 7News Spotlight special investigation to air on Sunday at 8.40pm on Seven and 7plus, Michael Usher explores the growing evidence these weight-loss drugs may help curb other addictive disorders like alcohol, smoking, gambling and drugs, opening up what some experts believe could be the next frontier of the "Ozempic" revolution.

The program examines the ground breaking science behind the drugs and meets Australians who say their relationship with food wasn't the only thing that changed, describing unexpected effects on long-standing addictions and compulsive behaviours. Plus, the research exploring whether the medications could help fight serious disease beyond obesity, including cancer.

But for all the promise, there are concerns. With health warnings about the potential risk of serious psychological impact and questions remaining about long-term side effects, 7News Spotlight investigates the ups and downs of the weight-loss drugs reshaping modern medicine.

7News Spotlight sees Sarah Greenhalgh inside Australia's AI data centres, processing everything from online searches and streaming services to the AI tools millions now use every day.

Across the country, giant data centres are springing up in suburbia and regional communities, some just metres from homes – powering every scroll, every search and every AI prompt reshaping our lives.

But the race to build Australia's AI revolution is also fuelling a growing backlash, with battles intensifying over water and electricity resources, infrastructure, pollution, and the impact on local communities.

As governments and tech giants lead the charge to secure Australia's place in the global AI boom, critics are raising concerns about the hidden costs. These facilities draw on enormous amounts of electricity and water, while communities fear the centres are being built too close to homes and without enough scrutiny.

From the NSW Southern Highlands to Melbourne's city centre, 7News Spotlight explores the rapid expansion of an industry expected to transform the country's economy, and meets the residents, experts and industry leaders grappling with the real-world impact of the data centres already on our doorstep.

The question isn't whether we need them. It's what we're prepared to sacrifice to keep them running. And 7News Spotlight heads to Loudoun County, Virginia – the data centre capital of the world – to see what lessons Australia can learn before it's too late.
