In May 1997, a large earthquake shook the Kermadec Islands region in the South Pacific Ocean. A little over 20 years later, in September 2018, a second big earthquake hit the same location, its waves of seismic energy emanating from the same region. Credit: Virginia Tech’s Ying Zhou.

Cornell is one step closer to determining the feasibility of using deep geothermal energy to heat the Ithaca campus. Drilling for the Cornell University Borehole Observatory (CUBO) began June 21 and is expected to last about two months. The borehole, located on a Cornell-owned gravel parking lot near Palm Road, will be subjected to a … Read more
As greenhouse effects become increasingly prominent, soil carbon has been a major focus of research on climate change. Soil microorganisms are the key groups that drive soil carbon transformation. Due to the complexity of factors such as microbial physiology, the composition of organic compounds in soils, and variation among redox forms, the pattern and process … Read more
University of Arizona astronomers have identified five examples of a new class of stellar system. They’re not quite galaxies and only exist in isolation. University of Arizona astronomers have identified five examples of a new class of stellar system. They’re not quite galaxies and only exist in isolation. The new stellar systems contain only young, … Read more

Harvestmen (Photo: Leo Lanna / National Geographic) Brazilian biologist, photographer, and National Geographic Explorer Leo Lanna is passionate about nature. And this passion has led him on a path to study the praying mantis. Since 2015, along with designer Lvcas Fiat, Lanna has been exploring the micro-world of insects thanks to his non-profit Project Mantis. … Read more
Using the Atacama Large Millimeter / submillimeter Array (ALMA), astronomers have imaged the debris disk of the nearby star HD 53143 at millimeter wavelengths for the first time, and it looks nothing like they expected. Based on early coronagraphic data, scientists expected ALMA to confirm the debris disk as a face-on ring peppered with clumps … Read more
When our sun exhausts the hydrogen fuel in its core some 5 billion years from now, it will expand to become a red giant, engulfing the inner planets. The dynamics and possible outcomes of planetary engulfment are poorly understood, but it is thought to be a relatively common fate for planetary systems. Credit: Image credit: … Read more
A new study led by the global Cancer Grand Challenges PRECISION team, including researchers from The University of Texas MD Anderson Cancer Center, shifts the long-held belief that all invasive breast cancers following ductal carcinoma in situ (DCIS) arise from the original DCIS lesion. The results, published today in Nature Geneticsdemonstrate that roughly one in … Read more
There’s no question that young solar systems are chaotic places. Cascading collisions defined our young Solar System as rocks, boulders, and planetesimals repeatedly collided. A new study based on chunks of asteroids that crashed into Earth puts a timeline to some of that chaos. Astronomers know that asteroids have remained essentially unchanged since their formation … Read more
