The stealthy, persistent hazard of thirdhand smoke

While the dangers of secondhand smoke are widely recognized, a new study led by Prof. Sun Yele at the Institute of Atmospheric Physics of the Chinese Academy of Sciences, has uncovered a more persistent and stealthy hazard lurking in indoor environments: thirdhand smoke. This

Predictive 'mismatch' leads to novel carbon capture method

When experimental results don't match scientists' predictions, it's usually assumed that the predictions were wrong. But new research into materials that pull carbon dioxide directly from the air shows how such mismatches can instead be powerful clues, leading to discoveries

Engineering the first reusable launchpads on the moon

Engineers need good data to build lasting things. Even the designers of the Great Pyramids knew the limestone they used to build these massive structures would be steady when stacked on top of one another, even if they didn't have tables of the compressive strength of those

How soil and human antibiotic resistance are connected

A study led by researchers at the Department of Civil Engineering at The University of Hong Kong (HKU) has uncovered alarming evidence that soil worldwide is emerging as a significant reservoir and amplifier of high-risk antibiotic resistance genes (ARGs), which enable bacteria

How greener bus stops can help people beat the heat

A new University of British Columbia study published in Urban Climate finds that people waiting at bus stops they find visually pleasant are more likely to feel thermally comfortable during hot weather, even when physical heat levels are high.

Hubble glimpses galactic gas making getaway

A sideways spiral galaxy shines in this NASA/ESA Hubble Space Telescope image. Located about 60 million light-years away in the constellation Virgo (the Maiden), NGC 4388 is a resident of the Virgo galaxy cluster. This enormous cluster of galaxies contains more than a thousand
