The search for a missing retired Brisbane teacher's remains, who is believed to have been dumped in a garbage bin, could take weeks or months.

Police believe 78-year-old Lesley Trotter's body was dumped in a general waste wheelie bin on Maryvale Street in Toowong near where she lives on March 28.

Foul play cannot be ruled out, police said.

Police Commissioner Katarina Carroll said the search through waste facilities for Trotter's body is going to be "tough going".

"(Police) have done an extraordinarily good job of isolating the areas that have to be searched," she said.

"Now the tough job starts of searching those areas thoroughly and, look, that might take days, but I've seen investigations like this in the past that take weeks."

The investigation could take months, Carroll warned, adding the discovery of her body could hold the key to finding out what happened to the retired teacher. 

"When you get the body of a person, you then have a lot more information available to you in terms of evidence and the forensics," she said.

"So, it's incredibly important that we do as much as we can in the next few weeks to find her."

Detective Superintendent Andrew Massingham said last week the rubbish truck that allegedly picked up Trotter's body last month was taken to Nudgee Transfer Station where the rubbish was dropped into a pit before an additional 22 trucks visited the site that day.

The loads from each of the trucks were compressed and taken away from the site in six B-double semi-trailers.

The trucks then took the loads to dump sites at Rochedale and Swanbank.

Police will commence an "extensive search" of both sites to try and recover Trotter's remains later this week.

Officers currently have no suspects in their investigation.

New data has revealed the Australian suburbs with the biggest drop in listings. Here is the top 20.

A man has admitted he murdered his estranged wife at their family home, confessing moments before a jury was to be selected for his trial.

Zoran Pandilovski was due to face the first day of a murder trial in Victoria's Supreme Court on Monday, but he pleaded guilty just before the empanelment process began.

He went to Elaine Pandilovski's home in the Melbourne suburb of Mill Park at 7.45am on July 14, 2020, where she was alone.

Pandilovski choked her to death and then tried to move her body to the basement of the home they once shared, to conceal it.

He then fled in his car and drove along Western Ring Road at a fast speed before crashing.

The facts of the case were previously revealed by Justice Christopher Beale.

Colleagues of Mrs Pandilovski, who worked as a teacher's aide at Plenty Park Primary School, became concerned when she did not show up to work on July 14.

They called her mother, who went to check on her but could not find her after searching through the property.

Police went to the home later that evening and found her body in a storage room of the basement.

The pair married in 2002 and had a son together before they separated in late 2018.

Last week, Pandilovski offered to plead guilty to manslaughter but prosecutors refused this and a jury was empanelled for his murder trial on Thursday.

That jury was discharged on Friday after a legal issue during selection where Justice Beale excused a retired police officer from serving as a juror.

He said he excused the former cop because there could be a reasonable basis for apprehended bias if he sat on the jury.

However, Justice Beale agreed with lawyers from both sides to start over with another jury to avoid any issues down the track if Pandilovski was convicted and then appealed.

Pandilovski was taken back into custody and will next face court on June 23 for a pre-sentence hearing.

An Austrian researcher has discovered a fragment of the Bible unseen for about 1300 years.

Grigory Kessel, from the Austrian Academy of Sciences (OeAW), was examining the manuscript in the Vatican archives when ultraviolet light revealed the remnants of the text beneath other writing.

The palimpsest – a manuscript that has been written over – has been dated to the 500s CE, and is believed to have been copied from an earlier Gospel written down in the 200s CE in Syria.

It's written in ancient Syriac on parchment, which was a rare material in the time, explaining the erasure of the original text and re-use of the pages.

Until recently, only two copies of the Gospels in Old Syriac were known to exist, and this one – containing verses from the Gospel of St Matthew – includes some differences from the first Greek texts.

In the Greek translation, Matthew chapter 12, verse 1 says: "At that time Jesus went through the grain fields on the Sabbath; and his disciples became hungry and began to pick the heads of grain and eat".

This Syriac translation says they "began to pick the heads of grain, rub them in their hands, and eat them".

It also predates any surviving Greek biblical translations by at least a century.

Claudia Rapp, director of the Institute for Medieval Research at the OeAW, said in a statement it was a "great discovery".

"This discovery proves how productive and important the interplay between modern digital technologies and basic research can be when dealing with medieval manuscripts," she said.

The Gospels – four books of the New Testament that chronicle the life and mission of Jesus – are believed to have been written in the first two centuries following his death.

The Gospels of Matthew and Luke are commonly believed to have drawn on an earlier, unknown text, nicknamed "Q" by researchers – making any discovery of a new version a historically significant find.

A Spanish mountain climber emerged on Friday from a cave 70 metres underground where she spent 500 days isolated from the outside world.

Beatriz Flamini, 50, of Madrid, left the cave in southern Spain shortly after 9am (local time) after being told by supporters that she had completed the feat she set out to accomplish on November 21 in 2021.

Spanish media said the spell underground set a new world record, but the claim could not be immediately confirmed.

The Spanish state news agency Efe later reported Flamini as saying she was obliged to temporarily halt the challenge after some 300 days and leave the cave for eight days because of a technical problem.

Efe said she spent the eight days in a tent but had no contact with anyone before going back down once the problem was resolved.

It was not immediately possible to contact Flamini or her team for comment on this incident.

Given that there are 509 days between April 14 and the day she started the project, it appears she spent at least 500 days underground with an interruption of eight days.

Blinking and smiling as she embraced well-wishers, Flamini's first words including asking who would be paying for a celebratory round of beers.

In brief comments to journalists, Flamini described the experience of being cut off from the world as "excellent, unbeatable."

She then asked to be excused as she needed her first shower in more than 16 months.

In 1987, Italian Maurizio Montalbini set a world record by spending 210 days in a cave.

Internet searches shows reports of a Serb who spent more than 460 days underground in 2016.

Flamini's pursuit was part of a project called Timecave that was designed to study how someone would fare going solo underground for so long.

Flamini used two cameras to document her experiences and placed the recordings at an exchange point in the cave, Efe reported.

Her teammates dropped off food and other necessities at the retrieval site and picked up whatever she left there.

A group of psychologists, researchers, speleologists and physical trainers with Timecave studied the recordings but did not have any direct contact with her.

At a press conference later Friday, Flamini said she felt she was still living in the day she went down in 2021 and had no idea what had gone on in the world since, including Russia's war in Ukraine.

With no sense of time, she said she stopped trying to count days after calculating she was down there some 60 days.

Flamini said that at no point did she feel like giving up, not even during an invasion of flies that she cited as the source of her worst memories.

"In fact, I didn't want to come out," she said.

Flamini said she used the time "to read, to draw, to weave, to be, to enjoy. I am where I want to be."

She admitted to missing certain things but said "this is part of the project".

"There is nothing to do but accept it," she said.

The climber apologised for stumbling over her answers to questions.

"I've been a year and a half without talking and I find it difficult," she said.

Noting that people at the news conference wore face masks, apparently to protect her from infections, Flamini joked it made her feel like it still was the height of the COVID-19 pandemic.

Witnesses said they heard two vehicles speeding before the crash, which happened at 5pm on Saturday.

The black Commodore ute was seen swerving around a truck on the single lane Hawksview Street in Merrylands, closely followed by a tailing sedan.

The ute clipped a Hyundai i30 performing a u-turn, flipping and slamming into a parked Toyota Hilux.

"We saw the big black car had flipped upside down, with three other cars around it," local woman Carol Malouf said.

Malouf said she heard people "screaming and shouting" for people to bring tools to try to get him out.

Another local woman, Jemma Achi, said he was unable to move, and she sat and comforted him before he died.

"I sat with him, telling him it was going to be okay," she said.

Mabany wife said she'd been "shattered me into a million pieces".

"I pray I can be strong enough to raise your six kids," she said, on Facebook.

The 23-year-old ute driver was taken to Westmead hospital with minor injuries and for mandatory testing, as was the man inside the white hatchback.

Police are now investigating if the driver was speeding or even drag racing the trailing black sedan.

Residents say the stretch is often used like a "race track" and have campaigned for safety measures.

Locals said they heard the car scream down the street moments before the collision.

The Volkswagen also took out a fence before coming to a halt in the playground at the bottom of a slippery-dip.

"Just the most horrific crash, bang, I was asleep and I woke up," Fran Walker said.

"Just a really loud bang, it sounded like an explosion to be honest, sort of like an electrical explosion," Chris Newton-Smith said.

"You could see some hazard lights and it looked like a car had sort of submerged itself in the play equipment."

The driver wasn't hurt.

He was reported for drink driving without due care and will appear in court at a later date.

His two passengers also escaped unharmed.
