Seeing the Yardang rock formations during sunset was a surreal experience. While they seem to have be standing in a sea of water that formed them, the fluid dynamics that actually lead to their existence is the result of wind abrasion by dust and sand and the removal of loose material by wind turbulence. The air flow and resulting pattern of erosion and the distribution of rocks determines their s ...[Read More]

July 22, 2013

Automatic weather stations (AWS) play a prominent role in making meteorological measurements in remote areas. These measurements can feed into climate models; providing better projections for rainfall, temperature and more. This peculiarly perched piece of equipment is just such a weather station: Out in the Swiss Alps, this AWS is making measurements of temperature, precipitation, wind speed, rel ...[Read More]

In the hours and days that followed many people living along the Israeli coast had to go to their nearest medical centre because they were experiencing respiratory problems, which appeared very similar to asthma. But what could have caused these breathing problems? Well in research recently published in Natu ...[Read More]
