Mozzies are causing Buruli ulcers in more parts of Australia. Here’s what you need to know
Warmer weather has arrived and mosquitoes will be buzzing about before you know it. As El Niño is expected to bring an early start to summer heat, it’s likely mosquitoes will make their presence felt earlier than usual. The threat of mosquitoes depositing flesh-eating bacteria has been restricted to a few parts of the country. But while rare, research shows it is now showing up in more areas – including in backyards in Melbourne’s inner city.

Flesh‑eating bacteria spread from possums and mozzies. But Buruli ulcers are preventable and treatable
A number of cases of the flesh-eating Buruli ulcer have now been detected on the New South Wales south coast. There is growing evidence mosquitoes are at least partly responsible for the spread of this “flesh-eating” bacteria, with possums also implicated. Health authorities have urged locals to avoid mosquito bites. Cases of Buruli ulcer are usually concentrated to parts of Victoria. So why is it being found in NSW? And how does a mozzie bite turn into a flesh-eating ulcer?
Schools should be AI-free
Schools should be AI-free Generative AI chatbots have only been available for three years, but are already widely used by school students. A national survey by the RAND Corporation in 2025 found that 54% of students were using AI for their schoolwork, a 15% increase from 2024.
Consider Many Factors before Choosing the Right Coating for a Particular Roof
To replace an aging roof or restore it by coating it? A growing number of building owners are opting for the latter. Contractors must then help them answer the follow-up question: Which type of coating (silicone and acrylic) to use? Roof coatings are not a one-solution-fits-all proposition. To understand how silicone and acrylic coatings perform and the jobs each is best-suited to, it is helpful to know a bit about their chemistry.
Are mosquito repellents safe to use? And do I really need them in Australia?

Insect repellent has become a routine requirement for time outdoors. But how safe are they? And do we really need them? What can go wrong after a mosquito bite?
Are mozzie repellents safe? Do I really need them in Australia?
This week, the potentially deadly Japanese encephalitis virus was detected in Australia for the first time this summer, in north-western Victoria. The virus claimed several lives in Australia last year, and is also known in NSW and Queensland. Another mosquito-borne virus, Kunjin virus, has also been detected in western NSW. The twin discoveries have alarmed health authorities. NSW Health’s director health protection Dr Stephen Conaty said the detections so early in summer were concerning.

Summer’s here and after a wet spring in many parts of Australia, mosquitoes are out in force. Insect repellent has become a routine requirement for time outdoors. But how safe are they? And do we really need them? What can go wrong after a mosquito bite? A bite from a mosquito can be itchy and irritating. Even a mild reaction can have us scratching, especially if you’re one of the people who are irresistible to mosquitoes. The swelling and itchiness usually resolves in a few days.
A warm, wet spring means more mosquitoes. How to protect yourself from the diseases they spread
Mosquito bites are annoying. They can also have deadly consequences. So what diseases do mosquitoes in Australia carry? And with warmer weather on its way and rain expected to continue, how can you prepare for the coming mosquito season? Mosquitoes are deadliest animal Mosquitoes kill more people than any other animal. Worldwide, more than half a million people die each year from mosquito bites that transmit malaria parasites.

Malaria has returned to the Torres Strait. What does this mean for mainland Australia?
Malaria is one of the deadliest diseases spread by mosquitoes. Each year, hundreds of millions of people worldwide are infected and half a million people die from the disease. While mainland Australia was declared malaria-free in 1981, from time to time travellers return to Australia with an infection. Infections from local mosquitoes are incredibly rare. However, last week two cases of locally acquired malaria were reported in the Torres Strait. So what does this mean for local communities?

Japanese encephalitis has claimed a second life in NSW and been detected in Brisbane
A second man has died from Japanese encephalitis virus in New South Wales on March 6, the state’s health authorities confirmed on Friday. Aged in his 70s, the man was infected while holidaying in the Murrumbidgee region. This follows the death of another man in his 70s in Sydney last month, after holidaying in the same region in January.

First wind, then rain. Next come the mozzies - here’s how to reduce your risk of bites and infections
While some parts of southeast Queensland and northern New South Wales are still on alert for flooding, others are starting the difficult clean-up process as flood waters recede. Stagnant water after floods provides the perfect breeding ground for mosquitoes. So as you clean up, remember to empty containers of water and other reservoirs around your house and yard such as water-filled boats, trailers and other large objects. Get rid of debris that may be collecting water too.

Head Lice Are Digging In, But There's a Simple Way to Get Rid of Them
Wrangling head lice, and the children they infest, must be up there with the most challenging duties a parent or carer has to face. And the job is getting harder. Commonly used chemical products aren't working as well as they once did, meaning head lice are harder to kill. You can still rid your children of lice – but it's likely to take some patience and persistence. Remind me, what are head lice? And nits?

Mosquito-borne diseases are on the rise-here's how collecting mozzies in your backyard can help science
Warm weather is here and mosquitoes are on the rise in Australia. Unseasonably large swarms are causing problems in some parts of Sydney already. Health authorities track mosquitoes across the country to provide an early warning of mosquito-borne disease risk, but they can't be everywhere. Citizen scientists can step in to help—with excellent success. Our latest research explored the value of an Australian program called Mozzie Monitors, not just as a surveillance tool but an educational one too.
Mosquito-borne diseases are on the rise. Here’s how collecting mozzies in your backyard can help science
Cameron Webb and the Department of Medical Entomology, NSW Health Pathology and University of Sydney, have been engaged by a wide range of insect repellent and insecticide manufacturers to provide testing of products and provide expert advice on mosquito biology. Cameron has also received funding from local, state and federal agencies to undertake research into mosquito-borne disease surveillance and management.

What causes the itch in mozzie bites? And why do some people get such a bad reaction?
Cameron Webb, University of Sydney Are you one of these people who loathes spending time outdoors at dusk as the weather warms and mosquitoes start biting? Female mosquitoes need blood to develop their eggs. Even though they take a tiny amount of our blood, they can leave us with itchy red lumps that can last days. And sometimes something worse. So why does our body react and itch after being bitten by a mosquito? And why are some people more affected than others? What happens when a mosquito bites?
