Several gecko species found during a series of surveys in a remote region of Cambodia have been confirmed as new to science.

Sinkholes can lead to road damage, inconvenience, and in some cases, injury. What causes them?

Sinkholes, often dramatic manifestations of karst geomorphology, result from the dissolution of soluble rock, such as limestone, dolomite, or evaporites, by naturally acidic groundwater.

Since the area where scientists discovered the sinkhole is known for its karst topography, the landscape around there is prone to dramatic sinkholes. Tech. Entertainment. Science.

Sinkholes are most common in karst terrains, where the rocks beneath the surface are limestone, carbonate rock, salt beds or another type of rock that is easily dissolved by running groundwater.

Where there are sinkholes, there is karst. While humans can cause sinkholes in areas without karst, the areas of Pennsylvania with the highest karst features are more susceptible to sinkholes.
