Butterflies create jet propulsion with a clap of their wings

The whimsical, wafting flight of butterflies may not give the impression of top aerodynamic performance, but research published on Wednesday suggests their large flexible wings could be perfectly designed to give them a burst ...

Watch how cells squeeze through channels

Observations of cells moving through small channels shed new light on cell migration in 3-D environments, researchers report October 6 in Biophysical Journal. The findings also reveal how cancer cells may penetrate tissues ...

Quantum materials quest could benefit from graphene that buckles

Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum ...

Detecting hidden nanostructures by converting light into sound

Researchers at ARCNL have found a way to detect nanostructures buried under many layers of opaque material using high-frequency sound waves induced by light. Their findings could have applications in the semiconductor manufacturing ...

The hidden underwater map of the past

Major climate changes leading to great fluctuations in sea levels took place during the Quaternary period 2.58 million years ago. The sea receded during the glaciations, because the water ended up stored in huge ice masses; ...

Eco-bike aims to cut pollution in Kathmandu

Where there's a will, there's a way. The truth of that saying was revealed once again to Lance Rake when he traveled to Kathmandu, Nepal, last year to develop a delivery version of the bamboo bicycles for which he is known.
