A 52,000-year-old woolly mammoth has had its entire genetic code mapped in a move it's hoped will further efforts to bring the giant ancient beasts back to life.

It is the first time such a feat has been achieved for any ancient fossilised remains.

It's hoped the same strategies could also be used on other ancient DNA samples, such as Egyptian mummies, in the future.

While many ancient DNA samples of fossilised ancient animals and people exist, most specimens consist of very small, scrambled DNA fragments.

However, this particular woolly mammoth discovered in Siberia happened to be freeze-dried by the weather soon after it died, preserving its DNA in a glass-like state.

The fossilised chromosomes extracted from the mammoth are around one million times longer than most ancient DNA fragments.

A team of US and Italian researchers set out to create a 3D map of these chromosomes in the same way scientists reconstruct the human genome.

"This is a new type of fossil, and its scale dwarfs that of individual ancient DNA fragments – a million times more sequence," study co-author Erez Lieberman Aiden, director of the Centre for Genome Architecture at Baylor College of Medicine, said.

Aiden thought that if the right ancient DNA sample could be found – one with the 3D organisation of the fragments still intact – it would be possible to use the same strategies as used on modern-day humans to assemble the ancient genomes.

The researchers tested dozens of DNA samples over the course of five years, before landing on an unusually well-preserved woolly mammoth excavated in northeastern Siberia in 2018.

The researchers extracted DNA from a skin sample taken behind the mammoth's ear.

Using a technique called Hi-C, they were able to detect which sections of DNA were likely to be located close together and to interact with one another in their natural state in the nucleus.

"Imagine you have a puzzle that has three billion pieces, but you don't have the picture of the final puzzle to work from," co-author Marc A. Marti-Renom, a structural genomicist at the Centre Nacional d'Anàlisi Genòmica in Barcelona, said.

"Hi-C allows you to have an approximation of that picture before you start putting the puzzle pieces together."

They were then able to use the genomes of modern-day elephants as a template to assemble that of the ancient species, which roamed the Earth's northern hemisphere for at least half a million years.

The analysis revealed that woolly mammoths had 28 chromosomes – the same number as present-day Asian and African elephants.

They also found the woolly mammoth's skin cells had distinctive gene activation patterns compared to those of its closest relative, the Asian elephant, including for genes potentially related to its woolly-ness and cold tolerance.

The scientists say that the next step for the woolly mammoth is to examine the epigenetic patterns of tissues other than the skin.

"These results have obvious consequences for contemporary efforts aimed at woolly mammoth de-extinction," M. Thomas Gilbert, a paleo-genomicist at the University of Copenhagen, said.

The results of the international study have been published in the scientific journal Cell today.

Gale force winds and rain deluges of up to 100mm will sweep over millions of Australians next week as a major polar outbreak brings severe weather to several states.

A large pool of cold air from waters near Antarctica will spread across south-eastern Australia from this weekend, Weatherzone has warned.

Temperatures are set to plummet into next week, with the probability of non-alpine snowfalls "from Tasmania to northern New South Wales".

The air mass will also create a low pressure system over the Tasman Sea that is forecast to linger into next week.

It's likely to bring damaging winds from Saturday to Tuesday in Tasmania, Victoria, and NSW, as well as heavy rain, Weatherzone said.

Gale force winds with gusts exceeding 90km/hr will sweep Tasmania and eastern Victoria on Sunday and Monday, with the damaging winds extending to NSW on Monday.

They could possibly range up to Sydney and Illawarra.

"The fierce winds that are predicted to hit southeastern Australia from this weekend have the potential to topple trees after a prolonged wet period has led to a soggy landscape," Weatherzone said.

"While winds should continue to be strong across eastern Australia on Tuesday, they should ease below damaging strength as the low moves further east over the Tasman Sea."

Heavy rain will also hammer Tasmania and Victoria from the weekend into early next week.

Forecasts are uncertain but both states should see falls of 30mm to 60mm in parts, with the potential for more than 100mm in some areas.

Weatherzone said the low pressure system could also bring heavy swell and dangerous surf along the east coast, with offshore waves larger than five metres near Tasmania, and four metres off Victoria and southern NSW.

Two Australian nationals and their Filipina companion have been killed in a hotel in a popular resort city south of the Philippine capital, with police trying to identify and track down the suspects, officials say.

A hotel worker found the bodies of the victims, whose hands and feet were tied, in a room at the Lake Hotel in Tagaytay city, south of Manila, on Wednesday, according to a police statement.

The Australian male victim's throat was slit with a sharp object that may have caused his death while the two women apparently may have been suffocated using a pillow, Tagaytay police chief Charles Daven Capagcuan told The Associated Press. Ongoing autopsies would verify those initial indications, he said.

Capagcuan said the motive for the killings was not immediately clear and added some valuables of the victims, including their cellphones, were not taken by the suspect.

"We were shocked by this incident," Tagaytay Mayor Abraham Tolentino said, apologising to the families of the victims.

"We're very sorry to our Australian friends. We will resolve this as soon as possible."

The victims were believed to be a man in his 50s from Australia, his Philippine-born partner and her Filipina relative.

Investigators were interviewing witnesses and examining security cameras at the hotel which could help identify the suspect or suspects, Tolentino said without elaborating.

Investigators were interviewing witnesses and examining security cameras at the hotel, including footage that showed a man wearing a mask and a hoodie and carrying a sling bag who walked out of the victims' room a few hours before their bodies were discovered, Capagcuan said.

A Filipino relative of the Australian woman told the AP that the Australian couple flew from Sydney to the Indonesian resort island of Bali for a vacation then headed to the Philippines on Monday to visit her two children from a previous marriage in the country.

The Australian couple was supposed to fly back to Australia on Wednesday, the day they were killed, but decided to briefly take a vacation in Tagaytay, said the relative, who asked not to be identified for security reasons.

Tagaytay, about 60 kilometres south of Manila, is popular among local and foreign tourists who flock there for its cool weather and to view one of the world's smallest active volcanos nestled in the middle of a lake.

Tolentino told the AP that the remains of the Australian man would be flown back to Sydney and the two women would be buried in the Philippines as requested by their relatives. The government would pay for the women's funeral and burial, he said.

A spokesman for the Department of Foreign Affairs and Trade said it was providing consular assistance to the families of the two Australians and expressed condolences to their families.

No other details were provided "owing to our privacy obligations", the spokesperson said.

A horrifying road rage incident that played out north of Brisbane has been captured on film.

Two cars were seen swerving within centimetres of each another on the Bruce Highway near Beerburrum yesterday afternoon.

The driver of a white hatchback could be seen throwing a beer bottle at the other car while moving through traffic.

Ron, a Gold Coast resident and witness, told 9News "it could have been catastrophic".

He said he was in front of the pair of cars when he looked in the rear-view mirror and saw a person hanging out of one car.

A person in one of the cars was standing up and allegedly abusing another car.

"I couldn't imagine anything much more stupid than that on the road at 110km/h," he said.

Ron's wife filmed the road rage on her phone as he drove.

Police are searching for the two drivers involved in the incident and are appealing for anyone who witnessed the exchange to come forward.

More than 100 teenagers have trashed a rental property in Melbourne's north-east, causing $12,000 worth of damage.

The property, described as a "serene retreat" in South Morang, was rented to a group of teenagers reportedly using a stolen credit card.

9News understands the teenagers organised a party at the weekend and charged a $20 entry fee.

Images obtained by 9News show windows smashed, holes in walls and doors destroyed.

In the days following, SMK Cleaning Group owners Codie Benson and Kylie Robinson were called to help clean the rental.

The cleaners told 9News they had never seen anything like it before.

"It made my stomach sick, there was the vomit, there was wee, there was poo, there was blood on the couch. I don't know what happened that night," Robinson said.

"We found like $12,000 of damage, we've got a skip full of rubbish we have had to throw out."

Neighbour Marialuisa Lo Piccolo said she was afraid the party was going to spill into their yard.

"It's frightening," she said.

Victoria Police said they were called to the property and asked the teenagers to move, which they did without incident.

Police are continuing to investigate.

Two men have been fined $17,000 for illegally dumping expired food outside a charity store in Sydney's west.

The pair were first caught on camera discarding about 40 boxes of Cheetos Puff snacks from a white van outside the Salvation Army store at Chester Hill in February.

A council investigation found the products expired last year and issued the driver a $2000 fine for transporting excess waste to an unlawful waste facility.

The same driver came back to the store with a friend in May, where they unloaded 60 boxes of yoghurt dips, which had expired in 2022, at the entrance.

This time, council issued them a $15,000 fine.

"I cannot believe someone would stoop so low, to donate out-of-date goods to a charity trying to assist those in need," Canterbury-Bankstown Mayor Bilal El-Hayek said.

"They have no shame and obviously don't realise the dire consequences of providing the expired products."

Lifeline commercial operations general manager Mark Jeffery said it was disappointing that charities were left to pay for the disposal of junk illegally dumped outside their stores.

"It's become a bigger problem with waste management, tip fees going up," he said.

With illegal dumping costing ratepayers $300 million each year, councils across the state were given greater powers to penalise offenders in April.

Corporations could face a fine from $15,000 to a maximum of $50,000 while individuals could see $25,000 to $75,000.

The most serious of offences have risen to $10 million.

"The fines have changed dramatically, there's some fines that have doubled five, six times," El-Hayek said.

"Hopefully this will deter people."

A new state government grant will allow councils to also install security cameras at dumping hotspots to catch those doing the wrong thing. 

Residents are encouraged to report instances of illegal dumping by calling Council on 9707 9000.
