Scimex Newsfeed Latest publicly released Scimex stories Online group course can help people with long COVID improve their health An online group course offering exercise and psychological support to people with long COVID can help improve their health, according to a team of researchers, including an Australian, who say the course is a cost-effective way to treat more people with the condition. The team recruited 585 adults with lingering symptoms they attributed to COVID-19, gave half of them a single online session of advice and support, and the other half a series of weekly group interventions over eight weeks. The researchers say health-related quality of life scores were higher for those who did the weekly sessions both three and 12 months after the study began. In an accompanying editorial, independent Australian researchers discuss what the study can tell us about the improvements that can be made for long COVID patients and how clinicians can best support them. 2024-02-08T10:30:00+11:00 Health / Medical Society / Lifestyle Australia International NSW VIC
After a heart attack in hospital, chances of survival drop rapidly as the duration of CPR increases Your chances of surviving while receiving cardiopulmonary resuscitation (CPR) for a heart attack in hospital decline rapidly from 22% after one minute to less than 1% after 39 minutes, according to US scientists. They also found the chances of avoiding major brain damage decline from 15% after one minute of CPR to less than 1% after 32 minutes with no heartbeat. Even in hospital, only around 25% of patients survive a heart attack, so the researchers looked at outcomes for nearly 350,000 US adults who had a heart attack in hospital between 2000 and 2021. They hope their findings will help hospitals improve their CPR performance.

What turned Earth into a giant snowball 700m years ago? Scientists now have an answer Inspired during field work in South Australia’s Flinders Ranges, Australian geoscientists have proposed that all-time low volcanic carbon dioxide emissions triggered a 57 million year-long global ‘Sturtian’ ice age. 2024-02-08T09:30:00+11:00 Environment / Climate / Energy Other Science Australia International NSW SA
Burnet research driving WHO guidelines on preventing maternal deaths New analysis by Burnet researchers has shown how care bundles can help improve health outcomes for women experiencing postpartum haemorrhage. Published today in the American Journal of Obstetrics & Gynecology, the study undertook a systematic review of evidence from studies on care bundles for postpartum haemorrhage prevention and management. It identified the key components of the best care bundles — including routine measurement of postpartum blood loss, effective training of medical providers, and regular measurement and monitoring to drive care improvements. 2024-02-08T08:00:00+11:00 Health / Medical Australia VIC
No single solution for changing people’s climate beliefs and behaviours In order to reduce climate change, people’s behaviour needs to change on a global level. Researchers tested 11 interventions on almost 60,000 participants from 63 countries, including New Zealand and Australia, to see what effect they had on outcomes such as climate beliefs, policy support, and tree-planting. While some interventions had effects, these varied depending on country, people’s initial climate beliefs, and which outcome was being measured. For instance, “doom and gloom” climate communications made people more likely to share climate information, but less likely to plant trees. The authors say that the small effects and high levels of pre-existing belief and policy support raise questions about how much “bottom-up” change can be made on a global level, and suggest that top-down change might need to be prioritised to achieve the emissions reduction necessary to stay within safe planetary limits. 2024-02-08T06:00:00+11:00 Environment / Climate / Energy Society / Lifestyle Business / Politics Australia New Zealand International
A move away from meat could help free up land for carbon removal Replacing half of our animal consumption with alternative protein sources over the next 25 years could free up farming land for renewable energy generation and carbon removal, according to international research. The team looked at the viability of a carbon dioxide removal method called ‘bioenergy with carbon capture and storage’, which involves cultivating fast-growing crops to capture and store carbon, and also using biomass as a feedstock for renewable energy. To do this successfully requires a lot of land, so the researchers estimated how much land could be freed up by switching out different percentages of animal consumption with protein alternatives. They say replacing 50% of animal products could free up enough land to generate renewable energy equivalent to today’s coal-generated power, however, more work will need to be done on the specifics of which protein alternatives could be used to reduce our meat consumption. 2024-02-08T03:00:00+11:00 Environment / Climate / Energy Society / Lifestyle Rural / Agricultural International
Aussie experts pave the way towards better measures of Alopecia severity Aussie experts have led a study that brought together hair and scalp experts from around the world to identify the factors that define Alopecia areata severity, to try and better capture the impacts of the disease. Alopecia areata is an autoimmune disease that causes hair loss, and current severity measures focus on scalp hair loss, without considering hair loss in other places, such as eyebrows, eyelashes and beards, or the psychological and social impacts of the disease. Now international experts have agreed that these non-scalp hair loss measures must be incorporated into any tool to measure severity, alongside other measures including a history of relapse, an inadequate repose to treatments, and psychological and social outcomes. 2024-02-08T03:00:00+11:00 Health / Medical Society / Lifestyle Australia VIC
One of Saturn’s moons might be hiding a secret ocean Saturn’s smallest major moon Mimas could be hiding an ocean beneath it’s cratered body, say international researchers. Before the final dive of the Cassini spacecraft into Saturn, the ship collected data suggesting that Mimas’ position and orbit is best explained by an internal ocean, the team say. They suggest there is a close to 20-30 km deep icy shell that hides the ocean on the moon, with their simulations suggesting it appeared between 25 and 2 million years ago. 2024-02-08T03:00:00+11:00 Tech / Engineering / Space International

New method to more accurately spot underground nuclear tests A more accurate way of identifying underground nuclear tests, including those conducted in secret, has been developed by researchers at The Australian National University (ANU). The new method could help international observers better identify tests carried out by countries or actors known to possess nuclear weapons, as well as provide new information about those suspected of being armed. 2024-02-08T00:01:00+11:00 Environment / Climate / Energy Australia International ACT
Air pollution linked to heart problem-related deaths across 183 countries Swiss and Russian researchers say their analysis of data from 183 World Health Organization (WHO) member states found a clear link between higher levels of air pollution and an increased risk of death from cardiovascular diseases, The link was stronger in lower-income countries, they say, with 70 deaths per 100,000 people, compared with 16 deaths per 100,000 people in wealthier countries. A major issue in lower-income countries was the use of polluting fuels and stoves in the home for cooking. The researchers say this accounted for more than twice as many deaths from stroke as outdoor air pollution, at 39 deaths per 100,000 people, compared with 19 per 100,000 people. The findings highlight the health risks of air pollution to our health and the need to consider it in addition to lifestyle changes and disease management to curb deaths from heart-related diseases, they conclude.

Unmanned vehicles beat out humans for safety and environmental factors The world’s first unmanned machine built to autonomously collect logs from the forest floor has been tested by Swedish researchers who say the robot can effectively reduce labour costs and minimise the environmental impacts of timber harvesting. The machine boasts the ability to navigate autonomously, spot fallen trees, safely, accurately, and efficiently pick up the logs, and manoeuvre them through forest terrains. The team say automating the process can be highly accurate and effective in terms of collateral damage to the surrounding ecosystems, leading to a more ecologically friendly sourcing of timber. 2024-02-07T19:01:00+11:00 Environment / Climate / Energy Tech / Engineering / Space International
Can we reliably predict sleepiness using voice recordings alone? International researchers think they may have found a way to detect sleep deprivation through voice recordings. The team studied 22 healthy women aged 30-50, who were sleep-deprived in a lab setting – with no more than three hours of sleep – and asked them to read chapters of the same book for about 10 minutes while their voices were recorded. Participants were also asked about how sleepy they felt – which varied greatly between participants from night to night despite everyone having the same amount of sleep. The team used machine learning to analyse the voice recordings and found sleep deprivation could be detected using two different effects: changes in rhythm of speech, and changes in voice quality. 2024-02-07T14:23:00+11:00 Health / Medical Tech / Engineering / Space International
How to provide effective falls prevention in aged care New research from Flinders University has revealed that devastating falls in residential aged care homes could be prevented by using gold standard approaches of regular exercise and a personalised falls prevention plan. Falls in older adults cost Australia’s health systems $2.5 billion each year and can have devastating personal consequences, with 130,000 older Australians hospitalised for a fall and 5,000 Australians dying from a fall each year. There is no current national strategy on preventing falls. 2024-02-07T13:05:00+11:00 Health / Medical Society / Lifestyle Australia International NSW SA
Women with HPV face higher risk of death from heart disease Women have a four times higher risk of dying from heart disease if they have an infection with a high-risk strain of the human papillomavirus (HPV), according to international research of 163,250 young or middle-aged Korean women who had no heart disease at the start of the study. After combining data on their HPV test results and other health checks over an average of 8.5 years, the team found that the risk of dying from heart disease in healthy women was relatively low (9.1 in 100,000 overall). However, women with high-risk HPV had a 3.91 times greater risk of blocked arteries, 3.74 times greater risk of dying from heart disease and a 5.86 times greater risk of dying from stroke, compared to women without the condition. An accompanying editorial by an Aussie researcher says the results add to evidence that viruses in general, particularly HPV, increase the risk of heart disease and poor health outcomes. These risks are compelling enough to add to the already strong case for vaccinations against HPV, as well as the flu, and COVID-19, he adds. 2024-02-07T11:05:00+11:00 Health / Medical Australia International NSW
How does AI respond to ethical dilemmas? AI language models apply strict ethical codes when making decisions… with some exceptions, according to international researchers. The team asked large language models (such as ChatGPT 3.5, GPT, Llama2 and PaLM 2) a series of moral questions and found they generally made decisions that align closely with human moral principles, such as saving human over pets and sparing females over males. However some, such as Llama2, deviated, taking a neutral stance on the lives of criminals vs non-offenders, for example. As AI becomes increasingly ingrained in every aspect of our lives, knowing how they make decisions is important, especially in decision-marking related to transport, for example, where safety trade-off decisions are constantly being made. 2024-02-07T11:01:00+11:00 Society / Lifestyle Tech / Engineering / Space Other Science International
We must tackle female ageism in sport and exercise science Sport and exercise science research is severely lacking in representation of older women, according to international researchers who say this problem must be addressed not only for the growing numbers of female athletes, but for women’s health in general. Out of 5,261 studies from across six popular sport and exercise science journals, the team found women and girls make up just over a third of participants – and this figure is likely to be even lower for women from mid-life onwards. As hormonal changes throughout a woman’s life increase the risk of muscle loss, osteoporosis, heart disease, and dementia, this may also affect the quality of life, but also willingness to exercise, athletic prowess, and response to training. The team is calling for more female-focused sports research, especially focusing on the effects of menopause and other hormonal changes on physical health and well-being across women’s lifespans. 2024-02-07T10:30:00+11:00 Health / Medical Society / Lifestyle Sport Other Science International
For those with type 2 diabetes, an hour of exercise goes a long way for your kidneys People with type 2 diabetes and overweight/obesity could lower their risk of kidney disease by adding an hour more of serious exercise a week, according to international research. The team used activity trackers to monitor the exercise of 1746 people with type 2 diabetes and overweight/obesity periodically over an average of 12 years to see how changes in exercise impacted their risk of developing kidney disease over the study period. The researchers say those who exercised the most each week were less likely to develop chronic kidney disease. Participants who increased their weekly amount of moderate to vigorous exercise by at least an hour over the first four years of the study had a 33% lower risk of kidney disease, the researchers say, noting the type of study cannot show the exercise caused the lower risk.

Ladies fair worse after a divorce It is likely that women find it harder to emotionally adjust after a divorce or breakup, suggest international researchers who tracked the antidepressant use of close to 230,000 people aged 50 to 70 who had lost a partner one way or another. The team say both sexes ramp up their antidepressant use in the run up to and immediate aftermath of a split, but they found women to use them more than men. The researchers say they found small falls in the antidepressant use among people who found another partner, but the levels tended to return or increase in subsequent years. This is an observational study, and as such, can’t establish cause, but they say their “findings underscore the challenges of adapting to union dissolution in later life and the associated need for support.”

Covid-19 vaccines saved thousands of lives in Aotearoa Aotearoa had one of the lowest Covid-19 pandemic mortality rates in the world, thanks to its elimination strategy that meant most people were vaccinated before being exposed to the SARS-CoV-2 virus. By modelling scenarios with different levels of vaccine coverage, researchers estimate that vaccines saved between 4,400 and 12,000 lives and prevented between 34,000 and 56,000 hospitalisations during the period from January 2022 and June 2023. They also say that equity needs to be a key focus of future vaccination programmes, as their results show that if vaccination rates had been equitable, an estimated 11%-26% of the 292 Māori Covid-19 deaths that were recorded in this time period could have been prevented. 2024-02-07T09:12:00+11:00 Health / Medical Society / Lifestyle Business / Politics New Zealand
Nitrogen pollution may threaten 1/3 of the world’s drinking water supplies by 2050 Nitrogen pollution may threaten a third of the world’s natural water reservoirs by 2050, potentially causing severe drinking water scarcity for 3 billion people, according to a computer simulation study by Dutch and German researchers. They say high levels of nitrogen pollution may mean many river sub-basins – an important source of drinking water – in South China, Central Europe, North America, and Africa become water scarcity hotspots. Urbanisation, particularly sewage, and other human activity, including agriculture, around rivers are the source of the pollution. The team analysed global river basins and found nitrogen pollution can render the water unsafe for drinking. In 2010, 984 sub-basins were considered unsafe for consumption, but their projections suggest this could rise to 3,061 by 2050. The findings highlight the need to prioritise water quality and pollution control, they conclude.

Bivalent COVID-19 vaccines protect kids and teens from infections Bivalent COVID-19 vaccines, which contain both the original strain of the virus and the Omicron variant, protected kids and teens from infections and COVID-19 symptoms better than the first, single-strain vaccines during a period when Omicron BA.4/5 variants were circulating, according to a US study. The study of almost 3000 kids found that the bivalent vaccines have an effectiveness of 54% against infection and 49% against symptomatic COVID-19. The authors say their data demonstrates the benefits of COVID-19 vaccines in children and adolescents. 2024-02-07T03:00:00+11:00 Health / Medical Society / Lifestyle International
How does COVID-19 impact the placenta and lead to a ‘pre-eclampsia-like sydrome’ ? For some women, having COVID-19 during pregnancy can impact their placenta and lead to a ‘preeclampsia-like syndrome’, and now Australian experts have identified some of the changes taking place in the placenta that might explain this syndrome. The researchers found that the products of genes linked to blood pressure, preeclampsia, and inflammation are increased in the placenta of women who contracted the virus in the third trimester of their pregnancy. 2024-02-07T03:00:00+11:00 Health / Medical Australia NSW QLD
For people who smoke, early stage melanomas are more likely to become deadly People with stage I and II melanoma who smoke are at higher risk of dying from their melanoma than those who don’t smoke or who have already quit, according to Australian research.

Stopping smoking at any age helps reduce cancer risk, but quitting younger helps even more Fifteen years after stopping smoking, a person’s cancer risk drops to 50% of the risk associated with continued smoking. A population-based study following almost three million participants in Korea found that quitting smoking at any age helps reduce the cancer risk, and stopping before middle age, especially for lung cancer, reduced the risk substantially. 2024-02-07T03:00:00+11:00 Health / Medical Society / Lifestyle International
Treating and preventing abnormal heart beats with stem cell muscle grafts New research conducted at The Westmead Institute for Medical Research (WIMR) has solved a complication that could occur following an experimental procedure to repair damaged heart muscle. Currently, when a heart muscle is repaired with stem cells, there is a risk of developing an abnormal heartbeat. The research, conducted on animal models, has found a way to identify cells that are likely to have an abnormal beat, and that a combination therapy of existing drugs can control and potentially stop this abnormality. 2024-02-06T21:00:00+11:00 Health / Medical Australia NSW
Discovery may enable an effective long-term lupus treatment Australian researchers have worked out how to fix a defect that causes lupus, and hope their discovery will offer effective long-term treatment. Published in Nature Communications, the Monash University-led study found a way to reprogram the defective cells of lupus patients with protective molecules from healthy people. Researchers hope this new method, developed in test tubes and proven in animals, can also be developed for other autoimmune diseases such as diabetes, rheumatoid arthritis, and multiple sclerosis. 2024-02-06T21:00:00+11:00 Health / Medical Australia VIC
WHO’s tobacco treaty linked to drop in young smokers About 24 million fewer young people are smoking as a result of the World Health Organization’s anti-smoking treaty, according to international research. The WHO Framework Convention on Tobacco Control came into force in the mid 2000s, and is a set of measures to decrease smoking including regulation of products, reduction of tobacco smoke exposure and regulation of tobacco promotion. To assess the effectiveness of the treaty, the researchers compared before-and-after smoking trends in 170 countries, and they say the treaty was associated with 2 million more people quitting smoking, along with decreases in the amount of current smokers and people smoking below the age of 25. Countries that adopted the treaty while also raising taxes by at least 10% were likely to see stronger improvements, the researchers add.

New pterosaur discovered UK researchers have uncovered the fossilised remains of a new species of pterosaur – the famous extinct clade of flying reptiles. The skeleton is incomplete, but three-dimensionally preserved, which helped the researchers learn more about pterosaur diversity and evolutionary history, they say. The researchers have named it Ceoptera evansae, and suggest it lived around 168-166 million years ago on the Isle of Skye in Scotland.
