Hopes chunks of meteor ‘might be found' after huge explosion
Footage of the fireball was shared by residents in Ballarat and Bendigo, who heard the boom approximately one minute after the sighting.
Geoscience Australia received multiple tremor reports but confirmed no seismic event occurred, attributing the effects to the meteor.
Experts believe significant chunks of the meteor likely survived the atmospheric entry, may have landed between Bendigo and Ballarat, and 'optimistically, might be found'.
The event was confirmed as a meteor and not space junk or part of the ongoing Perseids meteor shower, with a potential fall site identified northeast of Maryborough.

Fiery meteor sighting leaves onlookers in awe across Australia
A meteor caused widespread awe across Australia as people across the state of Victoria captured it falling to earth. Onlookers were left stunned when a bright object appeared to fall from the sky and hit the ground with a bang on Sunday (10 August). Footage from CCTV and dashcams shows the glowing object lighting up the nighttime sky, shocking onlookers. Scientists later confirmed that the flash was indeed a meteor, and the bang could have been a sonic boom - a loud noise created when an object travels through the air faster than the speed of sound.

3,000 steps a day at a faster pace may lower cardiovascular risks by 17%
Increasing daily step counts and walking faster may reduce risk of cardiovascular events in people with hypertension, a recent study has more than 3,000 steps each day reduced risk of major adverse cardiovascular events by 17%.The benefits of walking also reduced risk of cardiovascular events in people without more steps reduces the risk of major adverse cardiovascular events in people with published in the European Journal of Preventive Cardiology found that taking extra steps every day as well as walking faster reduced risk of heart attack, heart failure, and Stamatakis, PhD, director of the Mackenzie Wearables Research Hub at the University of Sydney, Australia, who supervised the study, said in a press statement that:'This study is one of the first to demonstrate a dose-response relationship between daily step count and major problems of the heart and blood vessels. In a nutshell, we found that, if you live with high blood pressure, the more you walk with greater intensity, the lower your risk for future serious cardiovascular events. These findings support the message that any amount of physical activity is beneficial, even below the widely recommended daily target of 10,000 steps.'3,000 steps a day may help lower cardiovascular risksAs part of their study, the researchers examined data from more than 32,000 people who were enrolled in the UK Biobank database. The participants had a diagnosis of high blood wore accelerometers on their wrist for a week to measure how fast and how far they researchers found that compared with a daily step count of 2,300 steps, taking more than 3,000 steps each day and taking regular walks at higher speed was associated with a 17% reduction in risk of major cardiac events in people with high blood every extra 1,000 steps taken daily, there was a 22% reduction in risk of heart failure, a 24% reduction in risk of stroke and a 9% reduction in risk of heart attack.'Our findings offer patients accessible and measurable targets for heart health, even below 10,000 steps daily. Clinicians should promote physical activity as standard care, especially in patients with high blood pressure. Our results can inform new, tailored public health recommendations for these patients. Future recommendations on walking in people with high blood pressure could consider promoting higher stepping intensity,' Stamatakis said in the press amount of exercise can make a difference for heart healthThe study adds to a growing body of research that demonstrates any amount of exercise can be beneficial to improving cardiovascular Chen, MD, a board-certified interventional cardiologist and medical director of the Structural Heart Program at MemorialCare Saddleback Medical Center in Laguna Hills, CA, not involved int his research, told Medical News Today that:'These results are significant in that they demonstrate a very clear dose-response relationship between walking and improvements in cardiovascular risk, even at low levels of walking. They indicate that even some physical activity is better than none, and that more is probably even better.' The study also concluded that taking any additional steps over 10 thousand a day was associated with additional benefits in reducing the risk of to Carl J. Lavie Jr., MD, Medical Director of Cardiac Rehabilitation and Preventive Cardiology at the John Ochsner Heart and Vascular Institute, walking has many advantages for improving health.'The benefits are numerous including improving autonomic function (the balance between vagal and sympathetic systems), improving cardiometabolic profiles, including metabolic syndrome and diabetes, reducing inflammation, and reducing psychological stress,' Lavie, who was likewise not involved in this study, said. 'One of the most important things that physical activity does to improve prognosis is improving levels of cardiorespiratory fitness. Higher intensity walking or exercise (e.g. faster steps, running etc) improves fitness even more, but compared to being totally sedentary, some steps improves fitness at least a little and moderate steps probably gets people out of the very low fitness categories,' he benefits those with and without hypertensionThe researchers also found a benefit of increased steps among those who do not have high blood pressure. They examined data from just over 37,000 people without hypertension and found that an extra 1,000 steps daily led to a 20.2% lower risk of major adverse cardiovascular events, 23.2% lower risk of heart failure, 17.9% lower myocardial infarction (heart attack) risk, and 24.6% lower risk of Physical Activity Guidelines for Americans recommends that adults need 150 minutes of moderate intensity physical activity each week. One way to do this is by taking a brisk walk 5 days a week for 30 Garg, MD, cardiologist with Keck Medicine USC, says that movement is the priority and that the number of steps taken does not necessarily need to be the focus.'I tell my patients, 'look, let's not get hung up on this 10,000 number'… If we just focus on that as the threshold, then a lot of people are going to feel like they failed, and they may not walk much at all,' Garg said.'So if we change that message to 'any walking is beneficial,' that's a much more positive message to our patients,' he advidsed.

‘Remarkable' new vaccine shown to slow down world's deadliest cancer in move to ‘beat cancer for everyone'
THOUSANDS of Brits with cancer have been given fresh hope as a new jab could slow down the disease and boost survival. The vaccine, described as "remarkable" by scientists, has shown promising results in the fight against one of the deadliest forms of the disease - pancreatic cancer. Early trials have proven the jab's ability to supercharge the immune system, enabling it to attack cancer cells and potentially prolong life for patients. More trials are now underway among a larger group of pancreatic and bowel cancer patients, as experts warn it is "too early" to say whether the jab will work at scale. Pancreatic cancer, which affects around 10,000 Brits each year, is the deadliest cancer in the world. And only about seven out of 100 of them will survive it for five years or more, according to Cancer Research UK. This is partly because it shows no symptoms until it has already spread to other parts of the body, making it incredibly hard to treat. While surgery, chemotherapy and radiation can help extend life, they rarely offer a cure. But researchers are now optimistic that this new vaccine could change that, providing a vital new treatment option other therapies fall short. 'Our results show that in the group of patients who had profound immune responses 68 per cent) we saw longer survival than we have expected in this cancer,' said Dr Zev Wainberg, study lead from the University of California, Los Angeles. 'Quite a remarkable finding to occur in a phase 1 trial.' The jab targets a mutated gene called KRAS, which is found in many pancreatic and bowel cancers. I'm a doctor, NEVER ignore these pancreatic cancer symptoms It's a type of immunotherapy vaccine designed to improve the immune system's ability to fight cancer by delivering the vaccine directly to the lymph nodes, which play a crucial role in immune defence. In the phase 1 trial, 20 pancreatic cancer patients and five bowel cancer patients received the vaccine. After 20 months, 68 per cent of patients developed strong immune responses. On average, the pancreatic cancer patients survived around two years and five months after receiving the vaccine, according to the study published in Nature Medicine. 'Patients with the strongest immune responses lived longer and stayed cancer-free for more than 15 months,' Dr Zev added. While some cancer jabs are personalised to each patient, this jab, ELI-002 2P, has a single version which can be given to all patients. This "off-the-shelf" version means that it can be manufactured in bulk and given more rapidly. Dr Chris Macdonald, head of research at Pancreatic Cancer UK, said: 'This study is a big step forward in treating pancreatic cancer. "The 'off-the-shelf' vaccine approach is quicker, cheaper, and could help many more people.' The study has already led to a phase 2 trial with 144 pancreatic and bowel cancer patients, with results expected in the coming months. Dr Dani Edmunds, research information manager at Cancer Research UK, added: "Although we've helped to double cancer survival in the UK in the past 50 years, progress has not been the same for pancreatic cancer which remains hard to treat. "Therefore, it's promising to see that vaccines could help people with pancreatic and bowel cancer live cancer-free for longer. "The results suggest that the vaccine can boost the immune system against cancer in some people following standard treatment. "These people survived and stayed free from disease for longer than people who didn't get as strong an immune boost following vaccination. "Larger controlled trials are needed to confirm these initial findings about the benefits of the vaccine. "More research is needed to understand why some people benefit from the vaccine while others don't so that we can make sure we're beating cancer for everyone." Dr Magnus Dillon, an oncologist at The Royal Marsden NHS Foundation Trust, said: "It's extremely promising to have a vaccine that seems to stimulate T cell activity in KRAS-driven tumours – these are generally 'immune cold', so therapies which stimulate immune responses in this group of patients are much needed. 'Many patients have these KRAS mutations, so an off-the-shelf vaccine could benefit lots of people – it saves the cost and time required to make a personalised vaccine. 'However, it's a bit early to definitively tell whether this will work to prevent cancer relapse in this group of patients who have had all disease removed at surgery - larger studies will be needed. "A bigger challenge is to see if the activated immune system could also work against established tumours, which have many ways to avoid immune attack and prevent immune cells from entering.'
