Countless inquiries have found the same problems afflicting the mental health system, but cost and access barriers still leave those seeking and providing care in despair Many Australians experience the country’s mental health system as inadequate, dangerous and financially punishing, saying they often feel unsafe in hospitals, are dismissed by health professionals and are hit with prohibitive...
Mike Whittaker has a suggestion to reduce test costs for those wishing to travel abroad, while Catherine Dunn says that if the government invested in public health infrastructure, we would have a more effective testing system Your article (Airlines warn the cost of Covid tests will stop people going abroad, 9 April) considers the cost of Covid tests for a family, calculated as the cost of a single...
This extraordinary image from the NASA/ESA Hubble Space Telescope of the galaxy cluster Abell 2813 (also known as ACO 2813) has an almost delicate beauty, which also illustrates the remarkable physics at work within it. The image spectacularly demonstrates the concept of gravitational lensing.
NASA's Parker Solar Probe mission has given scientists the first complete look at Venus' orbital dust ring, a collection of microscopic dust particles that circulates around the Sun along Venus' orbit. Though earlier missions have made some observations of Venus' orbital dust ring, Parker Solar Probe's images are the first to show the planet's dust ring for nearly its entire 360-degree span around...
NASA's Ingenuity Mars Helicopter could make its first flight over the Red Planet as soon as Monday, the US space agency reported, following a delay of more than a week due to a possible technical issue.
The man-made lakes that store water supplying millions of people in the U.S. West and Mexico are projected to shrink to historic lows in the coming months, dropping to levels that could trigger the federal government's first-ever official shortage declaration and prompt cuts in Arizona and Nevada.

Shawn Bath switched his underwater focus after experiencing an epiphany about the state of Newfoundland and Labrador's shorelines. As Andie Bulman writes, his work is the subject of a new...
The US and China announced actions to tackle climate change following meetings in Shanghai last week.
An exhibition at London’s Science Museum shows how far carbon capture research has comeTackling climate change may bring unexpected benefits, London’s Science Museum will reveal next month. A special exhibition on carbon capture, the fledgling technology of extracting greenhouse gases from the atmosphere and emissions from factories, will display bottles of vodka, tubes of toothpaste, pens and...
Properly managed carbon offset credits can play a significant role in reducing Canada's greenhouse gas emissions, writes Geoff...

It will be the largest crowd to have watched a football match in a...
Varying severity of COVID-19 symptoms in patients is reflected by levels of a chemical biomarker in their body which scientists say could be used to better manage treatments and other interventions, including vaccinations. In a new paper in International Journal of Infectious Diseases, medical experts in Italy and Australia examined levels of a chemical called serum amyloid A (SAA), a protein...
Heat stress disrupts the physiological processes of corals prior to clear signs of bleaching, with implications for adaptation strategies for coral reefs in a warming climate.
Solid-matrix catalysts called heterogeneous catalysts are among the most widespread industrial applications in reducing toxic gases, unburned fuel, and particulate matter in the exhaust stream from the combustion chamber. They are also used in energy, chemical, and pharmaceutical sectors, i.e., production of biodiesel, polymers, biomass/waste conversion into valuable products, and many others...
Researchers discovered, while exploring the photomechanical properties of diarylethene, that under irradiation with UV light the crystal of the compound peels off into micrometer-sized crystals at a world's fastest speed of 260 microseconds. As the material returns to its former molecular structure when exposed to visible light, the exfoliation method positions itself as a candidate for...
