Device cracks milk protein

Flinders University researchers have successfully manipulated Beta-lactoglobulin, a major whey protein in cow's, sheep's, and other mammal's milk, using an Australian-made thin film microfluidic device. The device combines with a new form of biosensor to control and monitor protein denaturation and renaturation.

How the brain paints the beauty of a landscape

A study published in Frontiers in Human Neuroscience found that brain activity associated with aesthetically appealing natural landscapes is not limited to the reward system, but also involves early visual areas. This suggests an early form of beauty perception that can be triggered by surprise and unexpected stimuli

New tracking system monitors danger to rainforests

Scientists have developed a novel indicator to monitor danger to the world's rainforests, which are losing their capacity to cycle carbon and water. The unique tropical rainforest index (TFVI) provides a snapshot of long-term observations, revealing that rainforests are more vulnerable than previously predicted.

Using silicone wristbands to measure air quality

A study by Texas A&M researchers found that silicone wristbands can be used as passive samplers to measure exposure to harmful chemicals during pregnancy. The wristbands yielded similar results to traditional testing methods, suggesting they could be a useful tool in studies of semi-volatile pollutants.

Land repair vital for survival

The study highlights the importance of dryland restoration to mitigate climate change and reverse desertification, with seeding efforts showing promising results in nearly a third of treatments. However, the process is also fraught with risks, including high failure rates and declining species populations as projects mature.

Scientists reverse age-related memory loss in mice

Researchers at the University of Cambridge and University of Leeds successfully reversed age-related memory loss in mice by manipulating the extracellular matrix of the brain. By restoring the balance of compounds known as chondroitin sulphates, they were able to restore neuroplasticity and alleviate memory deficits.

New insight on the reproductive evolution of land plants

A study published in Nature Plants reveals a comprehensive atlas of gene expression data from ten different species of land plants. The analysis identified novel and missing components involved in the formation of sex organs and cells, showing that many groups of genes emerged through the repurpose of existing genetic material. The tea...

Eco-friendly plastic from cellulose and water

Göttingen University researchers have developed a new type of hydroplastic polymer called cellulose cinnamate (CCi) that can be molded using little more than water at everyday temperature and pressure. The bioplastic exhibits high quality mechanical properties, making it suitable for various applications.

Study points to remotely supervised exercise classes as best option during lockdown

A study of 344 volunteers reveals that remotely supervised exercise classes were more effective than in-person sessions or unsupervised online sessions in improving physical and mental health. The researchers attribute this to the increased intensity of exercises under remote supervision, which led to better outcomes for participants.

Visualizing a city's energy use

A new model estimates annual energy use intensity of 209 structures in Pittsburgh with only a 7% error rate. The Urban Building Energy Model can aid policy makers in setting energy goals and efficiency regulations for commercial buildings.
