Were hot, humid summers the key to life's origins?

Uncovering how the first biological molecules (like proteins and DNA) arose is a major goal for researchers attempting to solve the origin of life. Today, chemists at Saint Louis University, in collaboration with scientists ...

Product authentication at your fingertips

Imagine if water vapor in your breath or surrounding your fingertips revealed invisible patterns on commercial products—smartphones, laptops, expensive liquor—that verified the products' authenticity and aided anticounterfeiting ...

Neotropical cloud forests to lose what most defines them: clouds

In as few as 25 years, climate change could shrink and dry 60-80% of Western Hemisphere cloud forests, finds a study published today. If greenhouse gas emissions continue increasing as they have been, 90% of Western Hemisphere ...

Scientists measure severity of drought during the Maya collapse

The severity of drought conditions during the demise of the Maya civilisation about one thousand years ago has been quantified, representing another piece of evidence that could be used to solve the longstanding mystery of ...

Novel hydrogel harnesses air moisture for practical applications

High humidity causes discomfort and makes hot days feel more unbearable. A team of researchers from the National University of Singapore (NUS) has invented a novel gel-like material that not only effectively dehumidifies ...

Super-heatwaves of 55 C to emerge if global warming continues

Heatwaves amplified by high humidity can reach above 40°C and may occur as often as every two years, leading to serious risks for human health. If global temperatures rise with 4°C, a new super heatwave of 55°C can hit ...
