Scientists have developed ionocaloric cooling, a new refrigeration process that could replace current methods and be safer and more environmentally friendly. The process involves using ions to force materials to absorb and shed heat energy, cooling the surroundings. Initial experiments with a salt made with iodine and sodium showed promising results, achieving a temperature shift of 25 degrees Celsius with less than a single volt of charge. The technology aims to address the environmental impact of traditional refrigerants, such as hydrofluorocarbons, and could play a significant role in reducing greenhouse gas emissions. Researchers now plan to scale up the technology for practical commercial use.

Study Suggests Isometric Exercises can Lower Blood Pressure and Promote Better Health
New research reveals that static exercises like planks and wall sits effectively lower blood pressure and provide a range of health benefits. These isometric exercises involve muscle contraction without changing muscle length. Conducting three weekly sessions of four two-minute bouts of isometric exercises reduces blood pressure akin to medication. These exercises also enhance heart health, […]
Reverberations from Earthquakes Reveal New Details about Earth’s Inner Core
A new study published in Nature Communications has used the reverberations from earthquakes to reveal new details about the structure of the Earth’s inner core. For decades, there has been evidence to suggest that the inner core is made up of distinct layers, but their properties have remained mysterious. To better understand the inner core’s […]
Stem cell therapy shows promise for restoring vision in preclinical study
Researchers from Duke-NUS Medical School, the Singapore Eye Research Institute, and the Karolinska Institute have developed a method to produce photoreceptor progenitor cells, the light-detecting cells found in the eye, from stem cells and then transplanted them into experimental models with damaged retinas. The preclinical study showed significant vision recovery, potentially marking the first step […]
