Using rigorous and detailed collection methods, a University of Minnesota Twin Cities-led research team was able to place the remains of fossil apes, such as Morotopithecus, within detailed habitat reconstructions.
How and where life began 3.5 billion years ago is still a mystery, but there are two things of which scientists are almost certain. First, for much of that time, life on Earth was almost exclusively microbial. Second, there must have been prebiotic precursor compounds such as amino acids, organic acids, and lipids available to jumpstart the formation of DNA, enzymes, and cell walls, and to set life on a path leading to the complex forms we see today.
At least five ice ages have befallen Earth, including one 635 million years ago that created glaciers from pole to pole.
Seismic arrays deployed in California’s Long Beach and Seal Beach areas detected more than a thousand tiny earthquakes over eight months, many of them located at surprisingly shallow depths of less than two kilometers below the surface.
A Texas Tech professor receives a grant to help address a challenge for the U.S. Air Force.
Earth is a dynamic and constantly changing planet. From the formation of mountains and oceans to the eruption of volcanoes, the surface of our planet is in a constant state of flux. At the heart of these changes lies the powerful force of plate tectonics—the movements of Earth’s crustal plates.
Gas emissions are the manifestation of activity occurring beneath the surface of a volcano. Measuring them lets researchers see what can’t be seen from the surface. This knowledge is vital for hazard monitoring and the prediction of future eruptions.
A new study reveals that the mass loss of lake-terminating glaciers in the greater Himalaya has been significantly underestimated, due to the inability of satellites to see glacier changes occurring underwater, with critical implications for the region's future projections of glacier disappearance and water resources.
Specialized portable radar could serve as an early warning system to reduce risk for humans working on shorefast sea ice, according to a recently published study.
Scientists often look to the past for clues about how Earth’s landscapes might shift under a changing climate, and for insight into the migrations of human communities through time.

Chemical and isotopic analysis of copper artifacts from southern Africa reveals new cultural connections among people living in the region between the 5th and 20th centuries according to a University of Missouri researcher and colleagues.
Geologists have long contested the structure of the Red Sea. Many regard it as an extended rift basin where two continental plates are actively moving apart, while others see it as a fully developed ocean with a mid-ocean ridge and seafloor spreading.
The magnetic field radiates around the world and far into space, but it is set by processes that happen deep within the Earth’s core, where temperatures exceed 5,000-degress C. New research from geophysicists at the University of Leeds suggests that the way this super-hot core is cooled is key to understanding the causes of the peculiarities - or anomalies, as scientists call them - of the Earth’s magnetic field.
A new study published today in the journal Nature brings scientists one step closer to knowing how or when massive quantities of water arrived on earth.
In decades past, scientists have been unable to conclusively identify human-associated microbes in samples collected above 26,000 feet. This study marks the first time that next-generation gene sequencing technology has been used to analyze soil from such a high elevation on Mount Everest, enabling researchers to gain new insight into almost everything and anything that’s in them.
Doublet Pool’s regular thumping is more than just an interesting tourist attraction. A new study led by University of Utah researchers shows that the interval between episodes of thumping reflects the amount of energy heating the pool at the bottom, as well as in indication of how much heat is being lost through the surface. Doublet Pool, the authors found, is Yellowstone’s thumping thermometer.
The Northwest Pacific coast of Mexico is an area struck by large earthquakes and tsunamis as a result of the interaction of two tectonic plates. However, to date, the structure of the continental margin and, therefore, the causes behind the generation of these natural hazards were unknown.
Even in their dark isolation from the atmosphere above, caves can hold a rich archive of local climate conditions and how they’ve shifted over the eons. Formed over tens of thousands of years, speleothems — rock formations unique to caves better known as stalagmites and stalactites — hold secrets to the ancient environments from which they formed.
Climate, tectonics and time combine to create powerful forces that craft the face of our planet. Add the gradual sculpting of the Earth’s surface by rivers and what to us seems solid as rock is constantly changing.
With the help of an underwater robot, known as Icefin, a U.S.-New Zealand research team has obtained an unprecedented look inside a crevasse at Kamb Ice Stream — revealing more than a century of geological processes beneath the Antarctic ice.
Previous research estimated that it took hundreds of million years for the ancient Earth's magma ocean to solidify, but new research from Florida State University published in Nature Communications narrows these large uncertainties down to less than just a couple of million years.
Antarctic bottom water (AABW) covers more than two-thirds of the global ocean bottom, and its formation has recently decreased. However, its long-term variability has not been well understood.
The claim a Dutch researcher predicted the February earthquake in Turkey and Syria would happen three days before it occurred is misleading. Despite the accuracy of his prediction, scientists cannot predict when and where an earthquake will occur.
East Africa’s iconic rangelands - under threat from climate change and human activity - have the potential to recover from repeated environmental shocks and degradation, a new study has concluded.
Land subsidence is a phenomenon wherein the Earth’s surface sinks downwards. It occurs mainly due to human activities, such as excessive groundwater extraction. It is a major global concern, affecting 19% of the world’s population.
Below are some of the latest articles that have been added to the Chemistry news channel on Newswise.
Today, a team of scientists and engineers from Woods Hole Oceanographic Institution (WHOI) left Charleston, SC aboard the R/V Neil Armstrong to begin test deployments in preparation for the installation of an Ocean Observatories Initiative (OOI) ocean observing system in its new location in the southern Mid-Atlantic Bight (MAB).
Residents of Southern Turkey were again jolted by a new earthquake Monday, this trembler reported by the U.S. Geology Survey (USGS) as 6.3 in magnitude. News reports state that scores of buildings that were damaged in powerful quakes on February 6 have been further damaged or outright collapsed. Virginia Tech’s Robert Weiss, who studies natural hazards, calls the devastating trio of earthquake “unusual,” but not “impossible.
An everyday quirk of physics could be an important missing piece in scientists' efforts to predict the world’s most powerful earthquakes.
Renaissance polymath Leonard da Vinci demonstrated frictional forces slow down the motion of surfaces in contact. Friction, he determined, is proportional to normal force. When two objects are pressed together twice as hard, friction doubles.
The rapid retreat of Thwaites Glacier in West Antarctica appears to be driven by different processes under its floating ice shelf than researchers previously understood.
The Japanese archipelago is actively undergoing seismic shifts due to interactions between the oceanic plate and the continental plate.
Geologists are interested in the sedimentary cycle – erosion from mountains that forms sand that is carried out to the ocean – because it’s foundational for understanding how the planet works.
Cornell University researchers have unearthed precise, microscopic clues to where magma is stored, offering a way to better assess the risk of volcanic eruptions.
Ongoing climate change driven by greenhouse gas emissions is often discussed in terms of global average warming. For example, the landmark Paris Agreement seeks to limit global warming to 1.5 ⁰C, relative to pre-industrial levels. However, the extent of future warming will not be the same throughout the planet. One of the clearest regional differences in climate change is the faster warming over land than sea. This “terrestrial amplification” of future warming has real-world implications for understanding and dealing with climate change.
“A combination of geological interpretations and thermal-orbital evolution models implies that Charon had a subsurface liquid ocean that eventually froze,” said SwRI’s Dr. Alyssa Rhoden, a specialist in the geophysics of icy satellites, particularly those containing oceans, and the evolution of giant planet satellite systems.
University of Miami College of Engineering faculty members Nurcin Celik and Derin Ural lived through the 1999 temblor that struck near the Turkish city of Izmit. They stand ready to offer their expertise in the aftermath of Monday’s disaster.
