Sea cave preserves 5 000-year snapshot of tsunamis

An international team of scientists digging in a sea cave in Indonesia has discovered the world's most pristine record of tsunamis, a 5 000-year-old sedimentary snapshot that reveals for the first time how little is known about when earthquakes trigger massive...

Gamma-ray telescopes reveal a high-energy trap in our galaxy's center

A combined analysis of data from NASA's Fermi Gamma-ray Space Telescope and the High Energy Stereoscopic System (H.E.S.S.), a ground-based observatory in Namibia, suggests the center of our Milky Way contains a "trap" that concentrates some of the...

Large, distant comets more common than previously thought

Comets that take more than 200 years to make one revolution around the Sun are notoriously difficult to study. Because they spend most of their time far from our area of the solar system, many "long-period comets" will never approach the Sun in a...

UK Met Office: High risk of unprecedented rainfall in the UK

New innovative research has found that for England and Wales there is a 1 in 3 chance of a new monthly rainfall record in at least one region each winter (October - March). In the last few years, several rainfall events have caused widespread flooding in the UK. In...

plastic waste

Over 9.1 billion tons of plastic have been produced and most of it thrown away

More than 9.1 billion tons of plastic have been manufactured since the material was initially mass-produced in the 1950s, according to "the first global analysis of all mass-produced plastics," which reports the majority has ended up in landfills or...

How strike-slip faults form, the origin of earthquakes

Structural geologist Michele Cooke calls it the "million-dollar question" that underlies all work in her laboratory at the University of Massachusetts Amherst: what goes on deep in the earth as strike-slip faults form in the crust? This is the fault type...

Study finds Earth’s magnetic field ‘simpler than we thought’

Scientists have identified patterns in the Earth’s magnetic field that evolve on the order of 1 000 years, providing new insight into how the field works and adding a measure of predictability to changes in the field not previously known. The discovery also...
