Researchers taking the wind out of cyclone devastation
Although Alfred was an ex-tropical cyclone by the time it reached Queensland in March, it still managed to cause over a billion dollars' damage.
For most, the toll had it landed as a Category 5 system generating winds in excess of 250km/h, doesn't bear contemplating.
Yet for an elite team of Australian National University researchers, it's the kind of scenario that lives rent free in their heads.
The group is on course to establish how aerosols might hold the key to stopping destructive cyclones in their tracks.
The small airborne particles have been shown to stunt storm development, according to the study's lead author Associate Professor Roslyn Prinsley.
With climate change making cyclones more dangerous, she is convinced innovative solutions have become crucial.
"Others have looked at the impact of aerosols on a fully grown cyclone, when it might be about to hit land," she explained.
"We thought, it may be easier to stop them before they start."
Prof Prinsley and her colleagues have already shown it's possible.
The trick lies in understanding the complex physics of how clouds form, including how tiny particles interact, how heat is released and how these processes impact one another other.
Past efforts to modify storms have failed because researchers couldn't reliably predict their behaviour. Without accurate forecasting models, attempts to alter cloud formation have largely proved to be guesswork.
However understanding how aerosols of different sizes disrupt extreme weather systems at the formation stage has provided the way forward.
"We found coarse aerosols initially dampen vortex acceleration, while fine or ultrafine aerosols boost it first but later weaken it more than coarse aerosols," Prof Prinsley said.
"Getting these aerosols to where they're needed is another challenge we're looking at - it would require several aircraft to disperse the aerosols over a few hours."
She is confident Australia will become a global leader in the somewhat obscure scientific space, with the coastline off Western Australia providing a ripe testing ground.
Cyclones that form there, the ones that will never hit land, are the best to test.
The ANU team is collaborating with a Silicon Valley start-up also aiming to weaken cyclones before they threaten lives.
The Australian research is the only long-term solution," according to Aeolus co-founder Koki Mashita.
"In many parts around the world, the intensification of these events due to climate change has already led to significant increases in insurance premiums.
"As we look into the next few decades, properties will truly become uninsurable and we will need to intervene."

Game-changing treatment triples blood cancer patients' chances of surviving
Don't miss out on the headlines from Cancer. Followed categories will be added to My News. A 'game-changing' Australian blood cancer treatment triples patients chances of surviving, being cancer free and avoiding serious, life-long complications, new research shows. The breakthrough is set to change a key part of blood stem cell transplants — which can have life-threatening side effects — and uses an existing, affordable drug. The research, led by Melbourne's Alfred Hospital and Monash University, has already prompted several Australian health services to switch to the new treatment and several other countries are expected to follow in their foot steps. The five-year trial involved multiple Australian and New Zealand hospitals and more than 100 leukaemia patients who had received a blood stem cell transplant from a matched donor. The transplants are a lifesaving blood cancer treatment that allow patients to receive healthy blood-making cells, but they are also high risk. About one in three patients reject the cells — a serious complication known as 'graft versus host disease', where the donor's immune system attacks their healthy organs. Alfred haematologist and Monash University Professor David Curtis said doctors gave patients a combination of drugs post-transplant to try and reduce that risk but it did not 'prevent it always'. He said they wanted to find a better option and their trial found a new, less toxic drug combination halved patients' risk of GVD without increasing the risk of a cancer relapse. 'In people who got the standard treatment, after three years only one in six were alive, free of their disease and without having suffered graft versus host disease,' he said. 'With the new treatment, it's one in two. You're three times more likely to be alive without disease and without having suffered graft versus host disease.' Professor Curtis said it was important to spare patients from GVD, which was fatal for a small proportion and, for others, a less deadly but chronic, disfiguring disease. 'It lasts basically forever,' he said. 'It can affect any organ, but it often affects people's skin.' Every year, about 150 of the 600 patients who get a blood stem cell transplants in Australia and New Zealand suffer a serious complication. Prof Curtis said it caused issues including cataracts, hair-loss and a tightening of the skin that could look like a bad burn, and medications weren't always effective. The Australian protocol swapped one of the two drugs used in the standard treatment with an affordable chemotherapy drug. The study was sponsored by the Australasian Leukaemia and Lymphoma Group and published in the New England Journal of Medicine. Leukaemia survivor Stephanie Jouhari, 27, was in the trial and received the new treatment after her cancer relapsed at the age of 22. Ms Jouhari, now in remission, said research that didn't just improve survival rates — but also what that post-cancer life looked like. 'I want to be where I can be, healed and healthy and at the same level as everyone else who's in my 20s as well and not feel like I've got all these other obstacles now to face for the rest of my life,' she said. 'It's already a difficult time so to make it less likely for there to be ongoing health issues . . . it's just huge . . . If we can continue funding and researching and doing these clinical trials, it'll just mean that the next group of people who unfortunately have to face this disease can walk away with much better prognosis but also a lot less suffering and trauma from the actual treatment itself.'

Australia holds cards as global lithium shortage looms
Despite undergoing an expected tenfold explosion over the next five years, international lithium production is destined to fall short of soaring universal demand for electric vehicles. The highly sought after alkali metal has become "as important as gasoline in the industrial revolution", according to Shanghai academic Qifan Xia. "While lithium reserves are substantial around the world, they are distributed unevenly across different countries," he explains. "So we were interested if the major EV markets can be self-sufficient." In fact, the world's biggest lithium markets - China, Europe and the United States - account for 80 per cent of global EV sales but simply won't be able, by 2030, to meet their own demands. For the planet's leading lithium producers - Australia and Chile - the future is therefore lucrative. Dr Xia and his team at East China Normal University estimate the economic superpower will need up to 1.3 million metric tons of lithium carbonate equivalent - a standard measure of lithium content - to meet its new electric vehicle quota. Europe could require 792,000 tons and the US 692,000. Based on existing and proposed mining projects for all three, China might be able to produce somewhere between 804,000 and 1.1 million tons of equivalent by 2030. Production in Europe could reach 325,000 tons and in the USA, between 229,000 and 610,000 tons. The predictions suggest even the most ambitious plans to expand domestic mining would fall short, even if projects begin quickly. Europe would face the largest gap, with modelling showing it would rely heavily on imports. The researchers also warn that increased imports by one region would directly reduce access for others, exacerbating supply constraints and straining international trade relations. In one scenario they calculated, an increase of 77 per cent in Chinese imports would mean imports to the US would drop by 84 per cent and to Europe by 78 per cent. Most of Australia's lithium is produced from hard-rock spodumene, in contrast to other major producers like Argentina, Chile and China, which produce it mainly from salt lakes. A 2023 estimate suggested Australian production will hit a cap of 1.2 million tonnes of equivalent by 2030 and it will remain the top producer but with a smaller proportion of the world's production. It is currently the biggest producer of lithium by weight, with most extraction undertaken in Western Australia including at the worlds largest hard-rock mine, Greenbushes. Dr Xia says other means of avoiding a looming lithium crisis might include adopting battery technologies that use less or no lithium, or shifting consumer focus to promoting public transport. "Our study showed that without immediate action to expand mining, diversify suppliers and rethink how we manage demand, the world risks delays in meeting critical climate and energy goals," he said.
