Some don’t like it hot: Thermal conductivity-switching bottleneck resolved
This challenge limits the functionality of ultra-small electronic devices. For practical applications, the solution to heat dissipation must incorporate a means of modulating the temperature at which the device changes its speed of heat transmission.

Exercise may reduce depression symptoms, boost effects of therapy: Research
“A lot of previous research on the effects of exercise on mental health, in general, have used very broad measures of wellbeing. What we were interested in, specifically, is: how does acute exercise – that is, one session of exercise in a day – influence the primary symptoms of depression,” said Jacob Meyer, a professor of kinesiology at ISU and the lead-author of both publications.
Study finds reducing carbon emissions won’t hurt economic growth
To reduce warming and maintain robust economic growth simultaneously, countries would need to stimulate significant increases in energy, resource efficiency
Aussie university researchers make breakthrough in increasing batteries lifespan
The breakthrough, published in the Nature Communications journal and released to the public on Monday, showed how an atomic-thin layer could be used to coat high-voltage lithium batteries to more than double their lifespan — increasing charge, discharge cycles from 500 to over 1,000.
African scientists call for better forests management to boost climate resilience
Speaking at a forum in the Kenyan coastal city of Mombasa, the scientists called for enhanced protection of Africa’s forested landscapes given their immense role in climate response, poverty alleviation, food and water security.
Scientists find that impact of social media on wellbeing varies across adolescence
In a new study published recently in Nature Communications, the researchers show that, in UK data, girls experience a negative link between social media use and life satisfaction when they are 11-13 years old and boys when they are 14-15 years old. Increased social media use again predicts lower life satisfaction at age 19 years. At other times the link was not statistically significant.

Long-term exposure to air pollution is linked to heightened autoimmune disease risk
Environmental air pollution from vehicle exhaust and industrial output can trigger adaptive immunity–whereby the body reacts to a specific disease-causing entity. But sometimes this adaptive response misfires, prompting systemic inflammation, tissue damage, and ultimately autoimmune disease.
