Trial hopes to fill 'real need' amid calls to review driver's licence requirements
The subject of driving regulations for older residents has become a hotly contested debate in Victoria in recent weeks after a 91-year-old motorist lost control of her car in Melbourne's east and ploughed into a playground, leaving a two-year-old boy in hospital and killing his grandparents.
The state's road minister, Melissa Horne, has since confirmed she asked her department to launch a review into the regulations around elderly drivers' licences, saying nothing is off the table. While many road safety advocates have praised the move, bodies representing older Aussies and doctors have placed the emphasis on ability rather than age.
Now, researchers at the University of the Sunshine Coast are hoping to provide physicians with 'better tools to accurately assess cognitive fitness' by examining brain activity and how it relates to driving.
'At present, there are no standardised assessment tools available to GPs and health practitioners to help them assess cognitive fitness to drive,' Senior Research Fellow Dr Kayla Stefanidis told Yahoo News. 'There is a real need for the development of valid and reliable measures of cognitive fitness to drive.'
Elderly driver trial could lead to standardised screening method
The trial is recruiting participants aged between 60 and 90 to perform 'computerised attention tasks' and simulate driving while their brain activity is measured by an electroencephalogram (EEG). The results will then be compared to a control group of people under the age of 30 who have been driving for at least three years.
'While a number of factors are important, we know that our ability to focus on the road is fundamental to safe driving,' Samantha Ellis, a PhD candidate at the MAIC/UniSC Road Safety Research Collaboration, said.
'As we age, it's natural to experience changes in our attentional abilities. While these changes are normal, it is important to understand how they may impact our driving performance.'
Unlike standard cognitive tests, the EEG allows researchers to measure brain activity associated with attention in real-time, Ms Ellis explained.
The Road Safety Research Collaboration (RSRC) is a partnership between the Motor Accident Insurance Commission (MAIC) and the University of the Sunshine Coast. The latest trial is part of a larger program of work being conducted within the RSRC aimed at developing a screening method for assessing cognitive fitness to drive.

Older drivers 'exposed' on Aussie roads after major shift
What are the current requirements for older drivers?
Currently, doctors and health professionals make such assessments without any standardised measures. 'The development of a cognitive screening tool would help GPs and other health professionals accurately identify whether a patient requires further testing,' Dr Stefanidis said.
'For older adults, it could also reduce costly and unnecessary assessments in older adults who do not require them.'
Victoria does not have age-based driving safety requirements, and the onus is on motorists themselves to declare any medical conditions that could impact their driving to the authorities. However, drivers aged 75 and older must renew their licence every three years, which can involve various tests.
In NSW, Queensland, the ACT and the Northern Territory, drivers older than 75 are required to have an annual health check, while older drivers in South Australia must complete self-assessments, which in some cases require sign-off from a GP. Once drivers in NSW hit 85, they must also undertake a practical driving test every two years.
In Western Australia, an annual medical assessment is required to renew a driver's licence after turning 80.
Dr Stefanidis said data collection for the study is expected to be completed in early-to-mid 2026. Anyone who wishes to take part can find out more here.

Fatality as 2 people fall from overpass in CBD
Two people are dead after falling from an overpass in the Sydney CBD, closing lanes of the Harbour Bridge on Saturday. Police are investigating how the people came to fall from the Western Distributor onto Harbour Street at about 9.45am. A man and a woman, both believed to be in their 40s, died at the scene. 'Officers from Sydney City Police Area Command have established a crime scene and have commenced an investigation into the circumstances surrounding the incident,' NSW Police said in a statement. Two southbound lanes of the Harbour Bridge have been closed. Authorities also closed off Harbour Street in the Sydney CBD to southbound traffic. The Transport Management Centre has urged motorists to allow extra time due to the incident. 'Southbound motorists should continue on the Western Distributor, before taking the Harris Street off-ramp, Harris Street, William Henry Street and Pier Street to access Harbour Street and the city's south,' the centre said.

Salton Sea not to blame for Coachella, Imperial air pollution, study says
For years, millions of dollars have poured into controlling dust that wafts off the exposed lake shoreline of the Salton Sea, hoping to solve a serious air pollution problem in the Coachella and Imperial valleys. But a new report finds that the dusty shoreline is only responsible for a small percentage of the pollution, prompting some researchers to emphasize that cleaner air inside people's homes, workplaces and schools could be more important in addressing the asthma and respiratory disease that plague the area. "My big takeaway is that there's so many different sources that what we really need to do is pivot away from source control to start protecting people where they're exposed,' said Michael Cohen, a senior researcher at the Pacific Institute and lead author of the report. Released Thursday, the report draws on data from local, state and federal agencies and finds that dust from the expanding dry shore of the Salton Sea accounts for less than 1% of total small particle pollution in the region. The Salton Sea Basin, Coachella Valley and Imperial Valley all violate ozone, or smog, limits. When averaged over the year, Imperial Valley and Salton Sea Basin have twice the state limit for larger particles. Recent research also suggests bacteria and hydrogen sulfide as pollutants of concern. The dust particles are made up of agricultural chemicals from miles of lettuce and spinach fields, manure from livestock operations, diesel exhaust, unpaved roads and fine debris from lithium mining. Previous reports from UC Riverside have called the area one of the most impoverished and environmentally deteriorated regions in California. This mix is why state and local agencies have long focused their attention on dust control projects, planting salt-tolerant vegetation and spreading gravel. To date, California has spent some $49 million to put in more than 3,000 acres of dust suppression around the Salton Sea. But pollution is coming from so many places that money may be best spent in other ways, the researchers say. 'It's just much more effective, more cost-effective to switch to exposure control ... because really, at the end of the day, we're trying to protect public health and improve the lives of people," Cohen said. That could mean focusing on distributing filters, weatherizing homes and alerting people when they should stay and avoid exercising outdoors. A 2023 survey by the UCR School of Medicine showed more than one in five children in communities near the Salton Sea have asthma — almost twice the state average. Some 29% of parents surveyed said their child has had wheezing or breath whistling in the past, most in the last 12 months. The Salton Sea's role in the region's air quality is amplified by its geography. As a desert basin bordered by mountains, it can trap pollutants. Since 2018, the Salton Sea no longer gets an inflow of fresh water, only agricultural runoff, so it is evaporating and shrinking while the exposed, dry lake bed area is expanding, feeding clouds of particulate. Wind patterns, including strong gusts that sweep across the lake bed and surrounding farmland, can also kick up fine, toxic particles and carry them into nearby towns — exposing more residents. Some of the communities have identified pesticides, open burning, road dust and farming operations as among their air priorities. The region includes Calipatria, Brawley, Riverside, Palm Desert and Indio as well smaller communities, many of them mostly Latino or Indigenous. It's not that the Salton Sea is ruled out as a health problem. Dr. David Lo, a UC Riverside professor who has focused for years on air pollution in the region, said certain particles can be especially harmful depending on their chemical or biological makeup. 'A tiny amount of toxic material, even if it's infinitesimally small, can still have really major health effects,' Lo said. If policy emphasis were to shift to indoor air quality, that would leave many people unprotected, said Aydee Rodriguez, environmental justice campaign manager for the nonprofit Alianza Coachella Valley. "We've been noticing an uptick … of asthma-related … emergencies, people having nosebleeds, people having migraines, people feeling dizzy, nauseous,' she said. 'My hope is that the people start to get together and start talking to each other," said study author Cohen. "About what the different agencies are doing, where they're investing their money and how they can leverage and optimize those investments in public health.'

James Webb Space Telescope uncovers 300 mysteriously luminous objects. Are they galaxies or something else?
When you buy through links on our articles, Future and its syndication partners may earn a commission. Hundreds of unexpectedly energetic objects have been discovered throughout the distant universe, possibly hinting that the cosmos was far more active during its infancy than astronomers once believed. Using deep-field images from NASA's James Webb Space Telescope (JWST), researchers at the University of Missouri identified 300 unusually bright objects in the early universe. While they could be galaxies, astronomers aren't yet sure what they are for certain. Galaxies forming so soon after the Big Bang should be faint, limited by the pace at which they could form stars. Yet these candidates shine far brighter than current models of early galaxy formation predict. "If even a few of these objects turn out to be what we think they are, our discovery could challenge current ideas about how galaxies formed in the early universe — the period when the first stars and galaxies began to take shape," Haojing Yan, co-author of the study, said in a statement from the university. To discover these objects, the team applied a method called the "dropout" technique, which detects objects that appear in redder wavelengths but vanish in bluer, shorter-wavelength images. This indicates the objects are extremely distant, showing the universe as it was more than 13 billion years ago. To estimate distances, the team analyzed the objects' brightnesses across multiple wavelengths to infer redshift, age and mass. JWST's powerful Near-Infrared Camera and Mid-Infrared Instrument are designed to detect light from the farthest reaches of space, making them ideal for studying the early universe. "As the light from these early galaxies travels through space, it stretches into longer wavelengths — shifting from visible light into infrared," Yan said in the statement. "This stretching, called redshift, helps us determine how far away these galaxies are. The higher the redshift, the closer the galaxy is to the beginning of the universe." Next, the researchers hope to use targeted spectroscopic observations, focusing on the brightest sources. Confirming the newly found objects as genuine early galaxies would refine our current understanding of how quickly the first cosmic structures formed and evolved — and add to the growing list of transformative discoveries made by the JWST since it began observing the cosmos in 2022. The findings were published June 27 in The Astrophysical Journal. Solve the daily Crossword
