The missing mass — what is causing a geoid low in the Indian Ocean?

The Earth’s interior is still a mystery to us. While we have sent missions to probe the outer reaches of our solar system, the deepest boreholes on Earth go down to only a few kilometers. The only way to learn what’s going on deep inside our planet, in...

Winter cold extremes linked to high-altitude polar vortex weakening

Over the last decades, the stratospheric polar vortex has shifted towards more frequent weak states which can explain Eurasian cooling trends in boreal winter in the era of Arctic amplification. When the strong winds that circle the Arctic slacken, cold polar air...

Giant tsunami reshaped California coastline

New evidence suggests a gigantic tsunami hit the California coast 900 years ago, removing three to five times more sand than any El Niño storm in history. Since large tsunamis hit the northwestern US every 300 to 500 years and the last occurred in January...

12 000 years ago, Florida hurricanes heated up despite chilly seas

According to new research by Michael Toomey and his colleagues from The Geological Society of America's Journal Geology, Category 5 hurricanes may have slammed Florida repeatedly during the chilly Younger Dryas, 12 000 years ago, as hurricane-suppressing effects...

Astronomers discover unusual spindle-like galaxies

Using the CALIFA survey, astronomer Athanasia Tsatsi (Max Planck Institute for Astronomy) and her colleagues studied the spindle-like galaxies and found that these slender galaxies, which rotate along their longest axis, are much more common than previously thought....

Comet K2 'The Record-Breaker' - farthest active inbound comet ever seen

Hubble Space Telescope has photographed the farthest active inbound comet ever seen, at a whopping distance of 2.4 billion km (1.5 billion miles) from the Sun (beyond Saturn's orbit). The comet is record-breaking because it is already becoming active under the...

Tectonic plates weaker than previously thought

Experiments carried out at Oxford University have revealed that tectonic plates are weaker than previously thought. The finding explains an ambiguity in lab work that led scientists to believe these rocks were much stronger than they appeared to be in the natural...

Dino-killing asteroid strike could have thrust Earth into two years of darkness

Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, new research finds. This would have shut down photosynthesis, drastically...

Prehistoric jungle tribes may have practiced land management of tropical forests in SE Asia 70 000 years ago

With the rise of permaculture farming practices based on ancient tribal wisdom, we have come to understand that jungles and rain forests can be extremely productive when managed effectively. Recent studies have indicated that our distant ancestors in Southeast Asia...

Mercury is altering gene expression

The mercury found at very low concentrations in water is concentrated along the entire food chain, from algae via zooplankton to small fish and on to the largest fish -- the ones we eat. Mercury causes severe and irreversible neurological disorders in people who...

Study explains anomaly in Earth's atmosphere over the Weddell Sea

A new study finds that the ionospheric anomaly over the Weddell Sea, near the tip of South America in the southeast Pacific Ocean, is likely influenced by proximity to auroral energy input, rather than by tilting magnetic fields. The anomaly was discovered in the...

Scientists improve forecast of increasing hazard on Cotopaxi volcano

An international team of scientists showed an increasing volcanic danger on Cotopaxi volcano in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR). The Andes region in which Cotopaxi volcano is located is known to contain...
