Fighting coastal erosion with electricity

Researchers have developed a bioinspired process to make marine sand more durable and resistant to erosion by applying a mild electric current. This natural cement reduces the need for expensive protection structures and provides a sustainable solution for strengthening global coastlines.

Rock steady: Study reveals new mechanism to explain how continents stabilized

A new study proposes that ancient cratons played a key role in stabilizing Earth's continents 3 billion years ago. The researchers suggest that the exposure of fresh rock to wind and rain triggered geological processes that ultimately stabilized the crust. This mechanism may represent a new understanding of how habitable planets evolve.

A miserable life on overcrowded Earth in 2100

A new Cornell University study suggests that without democratic population-control practices and resource-management policies, the world's 2 billion people will face a difficult life by 2100. The report predicts an optimal population of 2 billion, with a standard of living about half that of the United States in the 1990s.

Large Gene Study Questions Cambrian Explosion

A recent gene study challenges the popular Cambrian Explosion theory, proposing that major animal groups evolved steadily over 1200 million years. The research uses hundreds of gene sequences to calculate evolutionary timelines and suggests that many species existed before their fossils appeared.
