Published Webb reveals new structures within iconic supernova


NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant.
Published Scientists detect and validate the longest-period exoplanet found with TESS


Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.
Published New giant planet evidence of possible planetary collisions


A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash.
Published Breathe! The shape-shifting ball that supports mental health


A soft ball designed to support mental health by 'personifying' breath has been invented by a computer science student.
Published The scent of the afterlife unbottled in new study of ancient Egyptian mummification balms



A team of researchers has recreated one of the scents used in the mummification of an important Egyptian woman more than 3500 years ago.
Published How to write in water



Researchers have overcome a fundamental obstacles for writing and drawing lines, letters, and complex patterns within the bulk of a liquid.
Published Study ties fracking to another type of shaking



New research confirms fracking causes slow, small earthquakes or tremors, whose origin was previously a mystery to scientists. The tremors are produced by the same processes that could create large, damaging earthquakes.
Published Fiber optic cables detect and characterize earthquakes



The same fiber optic networks that provide internet can simultaneously act as earthquake sensors, as demonstrated in a new study.
Published California's winter waves may be increasing under climate change



A new study uses nearly a century of data to show that the average heights of winter waves along the California coast have increased as climate change has heated up the planet.
Published How to distinguish slow and fast earthquakes



Slow earthquakes are slow-slip phenomena that last many days or months, and you barely notice them. In 2007, researchers proposed how the magnitude and duration of earthquakes vary, which can help differentiate slow and fast earthquakes. Seismologists now bolster the proposed relation with more data. They suggest the presence of a speed limit to slow earthquakes and reveal physical processes that differentiate slow and fast earthquakes. Since slow earthquakes could indicate future fast earthquakes, monitoring and understanding them helps accurately forecast devastating earthquakes and tsunamis.
Published What can central Utah's earthquake 'swarms' reveal about the West's seismicity?



Much of central Utah's seismic activity comes in groups of small earthquakes. A study by seismologists examines 2,300 quakes occurring 40 'swarms' dating back to 1981, opening a window into Earth's crust in a geothermally active area.
Published Earth's Inner Core: Earth's solid metal sphere is 'textured'



Scientists used seismic data discovered Earth's inner core displays a variety of textures that it acquired will it formed from within the fluid outer core. The data set was generated over the past 27 years by a network of seismometers set up to enforce the nuclear test ban treaty.
Published Water storage capacity in oceanic crust slabs increases with age, researchers find



An international research team has discovered that a subduction zone's age affects the ability for it to recycle water between the Earth's surface and its inner layers. The more mature the subduction zone, the bigger the water storage capacity.
Published Turning old maps into 3D digital models of lost neighborhoods



Imagine strapping on a virtual reality headset and 'walking' through a long-gone neighborhood in your city -- seeing the streets and buildings as they appeared decades ago. That's a very real possibility now that researchers have developed a method to create 3D digital models of historic neighborhoods using machine learning and historic Sanborn Fire Insurance maps.
Published NeuWS camera answers 'holy grail problem' in optical imaging



Engineers have demonstrated full-motion video camera technology that can 'see' through light-scattering media. The research could potentially be used in cameras that peer through fog, smoke, driving rain, murky water and parts of the body that hide tumors and other lesions.
Published Research reveals sources of CO2 from Aleutian-Alaska Arc volcanoes



Scientists have wondered what happens to the organic and inorganic carbon that Earth's Pacific Plate carries with it as it slides into the planet's interior along the volcano-studded Ring of Fire. A new study suggests a notable amount of such subducted carbon returns to the atmosphere rather than traveling deep into Earth's mantle.
Published Geologists are using artificial intelligence to predict landslides



Many factors influence where a landslide will occur, including the shape of the terrain, its slope and drainage areas, the material properties of soil and bedrock, and environmental conditions like climate, rainfall, hydrology and ground motion resulting from earthquakes. Geologists have developed a new technique that uses artificial intelligence to better predict where and why landslides may occur could bolster efforts to protect lives and property in some of the world's most disaster-prone areas. The new method improves the accuracy and interpretability of AI-based machine-learning techniques, requires far less computing power and is more broadly applicable than traditional predictive models.
Published Researchers unearth the mysteries of how Turkey's East Anatolian fault formed



An international team has, for the first time, accurately determined the age of the East Anatolian fault, allowing geologists to learn more about its seismic history and tendency to produce earthquakes.
Published What are the characteristics of foreshocks for large earthquakes?



Seismologists agree that foreshocks are the most widely identified signal of an upcoming mainshock earthquake. But do these foreshock sequences have distinctive characteristics that separate them from aftershock sequences, and could these characteristics be used to help forecast mainshocks?
Published How urea may have been the gateway to life



Urea reacts extremely quickly under the conditions that existed when our planet was newly formed. This new insight furthers our understanding of how life on Earth might have begun.
