A technique using satellites to create twice-yearly elevation maps of US mountain glaciers provides new insight into thinning of glaciers in the lower 48 states.
The world's tropical forests are in 'a critical state' in which the extinction of rare tree species could be a tipping point, according to an international team of scientists who have developed an analytical method to map their biodiversity.
More than 11 years after the Lusi mud volcano first erupted on the Indonesian island of Java, researchers may have figured out why the mudflows haven't stopped: deep underground, Lusi is connected to a nearby volcanic system.
A new study linking paleoclimatology -- the reconstruction of past global climates --with historical analysis by researchers at Yale and other institutions shows a link between environmental stress and its impact on the economy, political stability, and war-fighting capacity of ancient Egypt.
For the first time, scientists have directly detected gravitational waves from the spectacular collision of two neutron stars, and at the same time detected visible light from the merger. The discovery, reported today by a collaboration of scientists from around the world, marks the first time that a cosmic event has been detected through both light and gravitational waves -- the ripples in space-time predicted a century ago by Albert Einstein's general theory of relativity.
In a study published today in the Journal of Geophysical Research Solid Earth, scientists at the University of Utah report that small seismic signals in lakes can aid science. As a record of wave motion in a lake, they can reveal when a lake freezes over and when it thaws. And as a small, constant source of seismic energy in the surrounding earth, lake microseisms can shine a light on the geology surrounding a lake.
'Kronos' is enhanced in metals and other rock-forming elements but not in volatiles, prompting a team of Princeton researchers to conclude that it absorbed as much as 15 Earth masses worth of rocky planets. Its twin, 'Krios,' does not show this unusual pattern of enhancement.
Building on existing information and databases relating to volcanic fatalities, scientists from the University of Bristol have, for the first time, been able to classify victims by activity or occupation and look at the distance of their death from the volcano.
University of Utah scientists have mapped the near-surface geology around Old Faithful, revealing the reservoir of heated water that feeds the geyser's surface vent and how the ground shaking behaves in between eruptions. The map was made possible by a dense network of portable seismographs and by new seismic analysis techniques.
New research shows that equatorial waves -- pulses of warm ocean water that play a role in regulating Earth's climate -- are driven by the same dynamics as the exotic materials known as topological insulators.
