A small vortex on the wing makes the elegance of birds' flight

One mystery of birds' flight is solved! The elegance of birds' flight, their seemingly effortless aerial turns and the softness of their landing, have been envied by many people. From countless observations, it has been known ...

Controlling air flow over wings during supersonic flight

EU-funded researchers evaluated control techniques of air flow over aeroplane wings during supersonic flight. The optimal wing design developed should lead to important reductions in noise, emissions and fuel consumption.

Foul fumes found to pose pollinator problems

A team led by researchers at the University of Washington has discovered a major cause for a drop in nighttime pollinator activity—and people are largely to blame.

Biological crusts affected by drought can still stabilize soils

Biological soil crusts are communities of cyanobacteria, fungi, lichens, and other living organisms that can bind grains together and reduce the susceptibility of soils to erosion by water or wind. Crusts dominated by cyanobacteria, ...

Understanding flow and sound through large-scale computations

In a research collaboration between the group of Professor Hiroshi Yokoyama of the Department of Mechanical Engineering and KOBE STEEL, LTD., flow, and acoustic fields in an expanding pipe with orifice plates were studied ...
