Young children who practice visual working memory and reasoning tasks improve their math skills more than children who focus on spatial rotation exercises, according to a large study. The findings support the notion that training spatial cognition can enhance academic performance and that when it comes to math, the type of training matters.

Geological knowledge is essential for predicting what areas in a tropical mountain range are more prone to have landslides, earthquakes and volcanic eruptions, and the catastrophic consequences that these events might have in the surrounding populations.

The work is a global assessment of Earth's 92,033 debris-covered glaciers and shows that debris, taken as a whole, substantially reduces glacier mass loss.

Deep pools below waterfalls are popular recreational swimming spots, but sometimes they can be partially or completely filled with sediment. New research showed how and why pools at the base of waterfalls, known as plunge pools, go through natural cycles of sediment fill and evacuation.

How can we determine how empty or full the soil reservoir is in areas that are difficult to access? Researchers have now demonstrated an elegant method to track groundwater dynamics in high mountains: They use seismic waves.

Combining natural salt marsh habitats with conventional dikes may provide a more sustainable alternative for fully engineered flood protection. Researchers studied how salt marsh management can be optimized for coastal defense purposes. They found that grazing by both cattle and small herbivores such as geese and hare and artificial mowing can reduce salt marsh erosion, therefore contributing to nature-based coastal defense.

Coral reefs provide many services to coastal communities, including critical protection from flood damage. A new study reveals how valuable coral reefs are in protecting people, structures, and economic activity in the United States from coastal flooding during storms.

The meristem of the gerbera is patterned on the molecular level already at a stage where no primordia or other changes are discernible by even an electron microscope.

A new method was developed for high-resolution detection of landslides based on seismic data. This method was applied to detect landslides that occurred during the transit of Typhoon Talas across western Japan in 2011. Multiple landslides were detected and located, including one in Shizuoka Prefecture, 400 km east of the typhoon's track. The results show that large and small landslides may follow the same scaling relationships. This method may help develop landslide emergency alert technology.

Coastal communities face increasing danger from rising water and storms, but the level of risk will be more closely tied to policy decisions regarding development than the varying conditions associated with climate change.
