Super-eruptions may give warning signs only one year ahead

A new study of quartz crystals in pumice from the Bishop Tuff in California reveals that volcanic super-eruptions capable of devastating the entire planet can give only one year warning ahead of its occurrence. The study site was in the Long Valley Caldera, that was...

Study shows neutrinos can exhibit quantum superposition states

A team of MIT physicists analyzed the oscillations of neutrinos, the subatomic particles that weakly interact with matter and can pass through our bodies by the billions per second without any effect. The study showed the particles can be in a superposition state,...

Why life on Earth took 5 million years to recover from the greatest mass extinction

A new study conducted by the researchers from the University of Edinburgh, Leeds, Gratz, Bremen, and Vienna, reveals why the recovery of life on Earth from the greatest mass extinction event that occurred during the Permian-Triassic Boundary, was delayed for five...

Ice melting 10 000 years ago caused radical climate shift in Europe and Africa

A team of researchers led by the Ruhr-Universität Bochum investigated how the meltwater from the ice sheet in North America produced a massive impact on climate conditions in northwest Europe and northwest Africa by the end of the most recent ice age, about 10...

San Andreas fault prone to low-frequency tremors caused by the gravitational pull of Sun and Moon

A new study, led by the US Geological Survey (USGS) scientists revealed the gravitational pull of Sun and Moon, responsible for inducing the tides, can also trigger special types of earthquakes on the well-known San Andreas fault. Researchers discovered the small,...

Study finds Alban Hills volcano near Rome is starting a new eruptive cycle, Italy

The Alban Hills (Colli Albani/Monte Albano), a 15-km (9-mile) semicircle of hills outside Rome, Italy was previously considered an extinct volcano. However, a new study finds the volcano operates on a 31 000-year cycle of eruption and dormancy and is now starting a...

The observed influence of gamma­-ray bursts on Earth’s magnetic field

Gamma Ray Bursts (GRBs) are the brightest explosions in the Universe. They are detected by orbiting space telescopes at the rate of about one a day. The number that could be detected from Earth should be much higher than the current rate, but the efficiency of the...

The role of ocean circulation in sudden climate changes during the last ice age

Ice cores from Greenland and Antarctica show that there was a period during the last ice age, when our planet experienced dozens of abrupt temperature shifts. Plummeting and rising again every 1500 years or so, those sudden temperature shifts wreaked havoc on the...

Antarctic sea ice growth explained by natural variability

A newly published study offers evidence that the negative phase of the Interdecadal Pacific Oscillation (IPO), which is characterized by cooler-than-average sea surface temperatures in the tropical eastern Pacific, has created favorable conditions for additional...

A Sea of Charge: Oceanic microstructures

Seawater is not very exciting when you look at it. It is, presumably, just water with salt and other minerals. To most of the denizens of Earth’s oceans, the sea is something quite different, a web of gel. According to an article from New Scientist magazine,...

Sierra Nevada not expected to restore its snowpack to pre-drought levels before 2019

A new research, resulting from the analysis of a 31-year span of NASA's Landsat satellite data, suggests the snowpack of Sierra Nevada will not return to its pre-drought levels before 2019. The datasets from the period between the 1985 and 2015, have resulted in...
