A maths team from the University of Malaga has created a computer system that simulates the behaviour of a tsunami.

A maths team from the University of Malaga has created a computer system that simulates the behaviour of a tsunami.

With a few equations and a computer solving them, in barely three minutes they can determine how a tsunami will spread, its speed, which zones will be affected and when the wave will arrive.

The EU-funded BIOWEB project finds that human and environmental factors are causing significant changes to marine ecosystems.

Marine ecosystems are constantly subject to anthropogenic and environmental factors that cause them to change. From fishing and pollution, to climate change and invasions of non-native species, these factors have existed since prehistoric times but little is known about their cumulative impact.

A new NASA study has found that melting ice and shifting rain patterns are causing the North and South Poles to drift, resulting in a dramatic shift in Earth’s polar axis.

Scientists and navigators have been accurately measuring the true pole and polar motion since 1899, and for almost the entire 20th century they migrated a bit toward Canada. But that has changed with this century, and now it’s moving toward the UK, according to study lead author Surendra Adhikari at Nasa’s Jet Propulsion Lab. The study has been published in the journal ‘Science Advances.’
