Good quality indoor air is crucial to our well-being, while impurities in the air can compromise our working capacity and health. Researchers have developed a new method for measuring indoor air quality, making use of fluorescent strains of nematodes.

Remapping the superhighways travelled by the first Australians reveals a 10,000-year journey through the continent

Science Daily - 03/02/2023
New research has revealed that the process of 'peopling' the entire continent of Sahul -- the combined mega continent that joined Australia with New Guinea when sea levels were much lower than today -- took 10,000 years. Sophisticated models show the scale of the challenges faced by the ancestors of Indigenous people making their mass migration across the supercontinent more than 60,000 years ago. This pattern led to a rapid expansion both southward toward the Great Australian Bight, and northward from the Kimberley region to settle all parts of New Guinea and, later, the southwest and southeast of Australia.

Energy-efficient construction materials work better in colder climates, say researchers

Science Daily - 03/02/2023
In a new study, researchers claim that the energy payback period of using phase change materials, new technology in the construction industry, is the shortest in a colder climate. The optimal location for their usage is the interior on the northern side of the building. The study provides informed answers regarding the application of PCMs to improve buildings' energy efficiency.

Researchers find a link between traffic noise and tinnitus

Science Daily - 03/02/2023
There is a correlation between traffic noise and risk of developing tinnitus, researchers have found. They point to a vicious cycle involving stress reactions and sleep disturbance as a potential cause. If you live near a busy road, it may increase your stress levels and affect your sleep. When we are under stress and sleep poorly, we may be at a higher risk of developing tinnitus.
