Researchers at Deakin University have found that women's muscle mass falls off a cliff after their early 40s if they don't use them enough.

It's linked to the decline in the sex hormones oestrogen and progesterone during menopause, making it much more difficult to rebuild muscle once it's lost.

NASA is cutting short a mission aboard the International Space Station after one astronaut fell ill, triggering the first medical evacuation in the station's 25-year history.

The four-member US-Japanese-Russian crew will return to Earth early even though NASA says the astronaut is stable and it is not an emergency.

The agency says it's also cancelled a planned spacewalk — and will leave fewer astronauts on board the station for now.

Several states, led by Tasmania, are pushing back against the federal government's proposed national gun buyback saying the plan lacks detail and could cost them millions.

Tasmania's Police Minister says any buyback should be fully funded by Canberra warning it could cost Tasmanians around twenty million dollars - and impact legitimate gun owners.

He says his state does back tougher measures to keep firearms out of the wrong hands but that all reforms should be properly funded and with proper consultation with the states.

There are currently 10 "major fires" in Victoria and 15 current emergency warnings in place across the state

Venezuela's political future and that of its 29 million citizens remains very much in flux after the U-S assault on the country and capture of its president nine days ago.

What's more certain is the future of the country's oil stocks with US President Donald Trump declaring he was taking over the sales of 30 to 50 million barrels of previously sanctioned Venezuelan oil.

Today, Mr Trump urged Cuba to "make a deal" or face consequences - including the loss of 35,000 barrels of Venezuelan oil sent to the island each day.

So what does America's oil-based diplomacy mean for global security - and the efforts to reduce fossil fuel reliance?

New South Wales has just recorded its deadliest year on the roads since 2017, with 355 lives lost in 2025.

The last fighters from the Kurdish-led Syrian Democratic Forces — or the SDF — have left the Syrian city of Aleppo following a ceasefire deal that allowed evacuations after days of deadly clashes.

Around 150,000 people fled the city after it was bombed by Syrian government forces in what they said were efforts to rid the city of SDF fighters.

It come as the US and its partner forces carried out large-scale strikes against Islamic State targets in Syria in retaliation for an attack on US forces in December.
