Three giant ‘doomsday fish' wash up in one week, but harbinger of calamity a damp squib, say experts
Bad luck comes in threes, according to the saying. And this week three ethereal oarfish, nicknamed 'the doomsday fish', have washed up on the shores of Australia and New Zealand.
Two headless specimens were found near Dunedin and Christchurch on New Zealand's South Island, following the discovery of an oarfish on Tasmania's west coast on Monday.
But scientists say there is no evidence of any link between oarfish sightings and imminent natural disaster.
Earlier in the week, an oarfish was found near the small coastal settlement of Aramoana, north of Dunedin. Another, washed up on Thursday at a stony beach near Birdlings Flat, a 45-minute drive from Christchurch.
Andrew Stewart, the curator of fishes at the Museum of New Zealand Te Papa Tongarewa, described the fish as 'beautiful' and 'otherworldly', with their 'purply-blue, silver and crimson' colours.
The museum had investigated collecting one of these 'magnificent and ethereal-looking fish', but seagulls arrived first and demolished their heads.

That was disappointing because heads contained a lot of key features, Stewart said, such as earbones, teeth and gill rakers. Otherwise, he said, 'when you've got an oarfish, you've got 8 metres in which every metre looks like every other metre – just rinse and repeat.'
Stewart said there were about 20 confirmed records of oarfish sightings in New Zealand.
Oarfish were probably the origin of sea serpent legends, he said. Although, there was little basis for their reputation as a harbinger of doom, given a peer-reviewed study in 2019 found no link between the appearance of oarfish and the arrival of earthquakes.
A/Prof Nick Ling, a fish ecologist from the University of Waikato, said sightings of oarfish are relatively rare.
'They live in the open ocean at significant depths and people just don't encounter them. So because of that, they're almost impossible to study.'
Oarfish, considered the longest bony fish in the world, hang vertically in the water and move by rippling their anal and dorsal fins, he said.
'They're really beautiful fish,' Ling said. 'It's an extraordinary kind of lifestyle, just kind of hanging there, vertical in mid-water, presumably waiting for your food to happen along.'

Urgent warning to Bunnings shoppers over popular product sold in stores
Scientists have raised the alarm over a popular plant sold in hardware stores across Australia which could cause billions of dollars in environmental damage. The Gazania flower, an ornamental plant originally introduced to Australia between the 1950s and 1970s, is now considered highly invasive. The species poses a major threat to local ecosystems and the economy with warnings it could cost the agricultural sector up to $5billion a year. The once-decorative flower has since spread across vast areas, including grasslands, sand dunes, stream banks, roadsides, wastelands, and farmland in Western and Southern Australia. It is particularly problematic in grain crop fields in low-rainfall regions of South Australia, where farmers are struggling to control it using standard herbicides. Gazania plants and seeds are widely available for purchase across Australia, including at major retailers like Bunnings, Amazon, and online garden stores. 'There are major concerns that Gazania is killing productive land with crops unable to compete against such a vigorous weed,' researchers from LaTrobe University said. Muhammad Adnan, a PhD student at the La Trobe Institute for Sustainable Agriculture and Food (LISAF), led a study on the weed's resilience. Thousands of seeds were collected from across Australia to test how they responded to different environmental conditions. The research found the seeds could survive and germinate under a wide range of stress factors, including light and temperature extremes, salinity, moisture, and varied burial depths. 'It suggests they could become a problematic weed year-round in many parts of Australia, potentially leading to high infestation levels,' Mr Adnan said. The Invasive Species Council has called for a nationwide ban on the sale of Gazania. 'Gazanias are not only overrunning native grasslands, coastlines and roadsides, they are moving into grain production areas, choking out crops and costing farmers,' Invasive Species Council Advocacy Manager Imogen Ebsworth said. In a statement to Daily Mail Australia, Bunnings said its sale of the flower complies with all relevant regulations. 'Like many nurseries and retailers, we sell a wide range of locally-sourced plants across our stores and we work hard to create an assortment that caters to customer preferences and demand,' a spokesperson said. 'As always, we closely follow all relevant local biosecurity regulations and the advice of regulators about the plants we sell.' The Victorian Government has officially listed Gazania as a highly invasive species, and South Australia banned the plant altogether in March 2021.

Major HIV breakthrough forces hidden fragments of the virus to emerge so it can be cleared from the body
Experts could have found a way to be one step closer to curing HIV for good. Researchers in Australia has developed a new treatment that forces hidden fragments of the virus - normally concealed within human cells - to emerge and expose themselves to the immune system. The breakthrough could enable the body, aided by antiviral drugs, to detect and destroy any lingering viral reservoirs. HIV has remained incurable because the virus can integrate itself into a cell's DNA, laying dormant and undetectable to both medication and immune defenses. Scientists said they've created a nanoparticle capable of delivering genetic instructions to infected cells, prompting them to produce a signal that reveals the virus's presence. Dr Paula Cevaal of the Doherty Institute and co-author of the study told The Guardian that the feat was 'previously thought impossible'. Cevaal said: 'In the field of biomedicine, many things eventually don't make it into the clinic, that is the unfortunate truth; I don't want to paint a prettier picture than what is the reality. 'But in terms of specifically the field of HIV cure, we have never seen anything close to as good as what we are seeing, in terms of how well we are able to reveal this virus. 'So, from that point of view, we're very hopeful that we are also able to see this type of response in an animal, and that we could eventually do this in humans.' The discovery was first revealed in the journal Nature Communications, where researchers said they were initially so astonished that they had to rerun the tests. Further research would be needed to determine whether revealing the virus would be enough to trigger an immune response, with tests only being carried out in the lab. It could still take years before clinical trials for the drug began, when it would have to go through rigorous testing before reaching consumers. However, the advance represents another step forward for the 1.2 million Americans currently living with an HIV infection - for which they took drugs daily. An estimated 31,800 people were believed to be infected every year, although that's a 12 per cent decline on five years ago. Globally, nearly 40 million people have the virus. The new nanoparticle's based on mRNA technology, the same as was used in covid vaccines made by Pfizer and other vaccine manufacturers. In their paper, the scientists revealed that they could deliver mRNA instructions to cells using the nanoparticle. The mRNA then instruct cells to generate substances that reveal the presence of HIV, but only if the virus was present. The study done in the laboratory was carried out in cells donated by HIV patients.

WA reefs experiencing 'worst coral bleaching event' ever to hit state
From the World Heritage-listed Ningaloo all the way to Ashmore Reef about 1,500 km north-east, Western Australia's reefs are turning white. Now, teams of government scientists are reporting widespread coral death as they warn of widespread bleaching caused by increasing water temperatures.
