About 13 million years ago, a distant ancestor of modern apes and humans suffered an untimely death on the arid landscape of northern Kenya. Last year, a Rutgers scientist helped bring its tiny skull to light, filling in a huge gap in the evolutionary record. And on Saturday, members of the public are invited to come face-to-skull with that ancestor, known as “Alesi,” at the Rutgers Geology Museum’s 50th annual Open House event. The museum stands on the College Avenue Campus of Rutgers University–New Brunswick. Admission is free.
Tropical forests span a huge area, harbor a wide diversity of species, and are important to water and nutrient cycling. Researchers used high-tech tools to more precisely view where these cleared sites were and the lasting impact they had on the rainforest in the South American Amazon Basin.
Danny Bowman, a Sandia National Laboratories geophysicist, launched a fleet of five solar-powered hot air balloons last year. They reached a height of 13 to 15 miles, twice as high as commercial jets, and detected the infrasound from a test explosion. Infrasound is sound of very low frequencies, below 20 hertz, which is lower than humans can hear, and can be used to monitor explosions, including those caused by nuclear tests. Bowman is also working with NASA to explore the possibility of sending these balloons to Venus and Jupiter.
The new study shows that locations that experienced earthquakes are tied in proximity and timeliness to mass waste water injection sites. Further, the study indicates that tracking annual data on the injection well locations can help predict how corresponding earthquake activity will change. This new finding builds on previous studies showing that earthquake activity increases when wastewater injections increase.
S&T’s Office of Standards understood the need to gather in-depth data to determine how to construct the next-generation icebreaker. To do that, they needed to see, first hand, how changes to the current construct reacted to ice.
Among the initial 18 scientists selected for French President Emmanuel Macron's "Make Our Planet Great Again" program is Louis Derry, professor of earth and atmospheric sciences in Cornell University’s College of Engineering and faculty fellow with the Atkinson Center for a Sustainable Future.
Though mass extinctions wiped out staggeringly high numbers of species, they barely touched the overall "functional" diversity--how each species makes a living, be it filtering phytoplankton or eating small crustaceans, burrowing or clamping onto rocks. University of Chicago scientists documented this surprising trend in a study on extinctions published Jan. 5 in the Proceedings of the National Academy of Sciences.

The Anthropocene epoch — the proposed name for this time of significant human effect on the planet and its systems — represents a new context in which to study literature. A new book of essays co-edited by a University of Washington English professor argues that literary studies, in turn, also can help us better understand the Anthropocene.

Geologists have corrected a mix-up that made an ancient geological structure in the central U.S. seem hundreds of miles shorter than it really is. The biggest failed rift known to geologists is even bigger than originally thought, according to research that will be presented at the American Geophysical Union fall meeting Dec. 11 in New Orleans.

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown for the first time that dark fiber – the vast network of unused fiber-optic cables installed throughout the country and the world – can be used as sensors for detecting earthquakes, the presence of groundwater, changes in permafrost conditions, and a variety of other subsurface activity.
Most volcanoes erupt beneath the ocean, but scientists know little about them compared to what they know about volcanoes that eject their lava on dry land. Researchers think that with improved monitoring, they can learn more about these submarine eruptions, which threaten travel and alter the ocean soundscape. During the 174th ASA meeting, held Dec. 4-8, 2017, in New Orleans, Gabrielle Tepp of the USGS will discuss the challenges and benefits of remote monitoring and what it can teach about submarine volcanoes.
There are out-of-the-way places. There are remote places. Then there are places like the Trans-Antarctic Mountains, where the nearest human being – possibly, the nearest living organism – is at least 150 miles away. That’s where Rutgers University-New Brunswick planetary geologist Juliane Gross will spend six to eight weeks, beginning in December. An associate professor of earth and planetary sciences in the School of Arts and Sciences, she will recover meteorites for the Case Western Reserve University's Antarctic Search for Meteorites (ANSMET) program, funded by the National Aeronautics and Space Administration (NASA).
Slowly but steadily, an enormous mass of warm rock is rising beneath part of New England, although a major volcanic eruption isn’t likely for millions of years, a Rutgers University-led study suggests. The research is unprecedented in its scope and challenges textbook concepts of geology.
Researchers at the University of New Hampshire are using scientific sleuthing to better understand the journey of magma in Mount Etna, to create a more accurate picture of the volcano’s plumbing system and determine how quickly the magma rises to the top to cause an eruption. Their findings contribute to our understanding of how and when volcanoes erupt.
The amount of biomass – life – in Earth's ancient oceans may have been limited due to low recycling of the key nutrient phosphorus, according to new research by the University of Washington and the University of St. Andrews in Scotland.
Volcanism is sometimes like food poisoning, where the Earth spews forth unstable material. New research from Michigan Technological University, University of Wisconsin Oshkosh and ETH Zurich shows that a significant pulse of volatile carbon was released from the Earth’s mantle around 500 million years ago. But why?
WASHINGTON _ Dr. Francisca Oboh-Ikuenobe of Missouri University of Science and Technology has been named a fellow of the American Association for the Advancement of Science (AAAS) for her contributions to the advancement of palynology ─ the study of organic-walled microfossils such as pollen and spores ─ and her outstanding efforts in educating the next generation of Earth scientists.

Rural counties continue to rank lowest among counties across the U.S., in terms of health outcomes. A group of national organizations including the Robert Wood Johnson Foundation and the National 4-H Council are leading the way to close the rural health gap.
Using a sophisticated computer model, scientists have demonstrated for the first time that a new research approach to geoengineering could potentially be used to limit Earth’s warming to a specific target while reducing some of the risks and concerns identified in past studies, including uneven cooling of the globe.
Long Valley, California, has long defined the “super-eruption.” About 765,000 years ago, a pool of molten rock exploded into the sky. Within one nightmarish week, 760 cubic kilometers of lava and ash spewed out in the kind of volcanic cataclysm we hope never to witness. A new study shows that the giant body of magma — molten rock — at Long Valley was much cooler before the eruption than previously thought.

Scientists around Tetyana Milojevic from the Faculty of Chemistry at the University of Vienna are in search of unique biosignatures, which are left on synthetic extraterrestrial minerals by microbial activity. The biochemist and astrobiologist investigates these signatures at her own miniaturized "Mars farm" where she can observe interactions between the archaeon Metallosphaera sedula and Mars-like rocks. These microbes are capable of oxidizing and integrating metals into their metabolism. The original research was currently published in the journal "Frontiers in Microbiology".
Carbon dioxide measured by a NASA satellite pinpoints sources of the gas from human and volcanic activities, which may help monitor greenhouse gases responsible for climate change.
