A new study that incorporates datasets gathered from more than 100 sites by institutions including the U.S. Department of Energy's (DOE) Argonne National Laboratory, suggests that decomposition of organic matter in permafrost soil is substantially larger than previously thought, demonstrating the significant impact that emissions from the permafrost soil could have on the greenhouse effect and global warming.
Scientists from Cornell University and Brookhaven National Laboratory (BNL) have successfully demonstrated the world's first capture and reuse of energy in a multi-turn particle accelerator, where electrons are accelerated and decelerated in multiple stages and transported at different energies through a single beamline.
It represents an entirely new type of ground state for transition metal oxides, and opens new directions for experiments and theoretical studies of how superconductivity arises and how it can be optimized in this system and possibly in other compounds.
Experimental physicists have combined several measurements of quantum materials into one in their ongoing quest to learn more about manipulating and controlling the behavior of them for possible applications. They even coined a term for it-- Magneto-elastoresistance, or MER.
In a new study, scientists have developed a new type of semiconductor neutron detector that boosts detection rates by reducing the number of steps involved in neutron capture and transduction.
Astrophysicists have come a step closer to understanding the origin of a faint glow of gamma rays covering the night sky. They found that this light is brighter in regions that contain a lot of matter and dimmer where matter is sparser - a correlation that could help them narrow down the properties of exotic astrophysical objects and invisible dark matter.
A new DNA-programmable nanofabrication platform organizes inorganic or biological nanocomponents in the same prescribed ways.
Scientists often make progress by coming up with new ways to look at old problems. That has happened at PPPL, where physicists have used a simple insight to capture the complex effects of many high-frequency waves in a fusion plasma.
An international team of researchers have, for the first time, glimpsed the ultrafast process of proton transfer following ionization of liquid water, shedding light on how radical cations separate from their electron partners, neutralize and subsequently drift about creating damage.
A protein newly identified as important in type 1 diabetes can delay onset of the disease in diabetic mice, providing a new target for prevention and treatment in people, according to research led by scientists at the U.S. Department of Energy's Pacific Northwest National Laboratory and Indiana University School of Medicine.
The largest set of data yet from an underground experiment called CUORE sets more stringent limits on a theoretical ultra-rare particle process known as neutrinoless double-beta decay that could help to explain the abundance of matter over antimatter in the universe.

A new study offers a nanoscopic view of complex oxides, which have great potential for advanced microelectronics.
Evaporation ponds, commonly used in many industries to manage wastewater, can occupy a large footprint and often pose risks to birds and other wildlife, yet they're an economical way to deal with contaminated water. Now researchers at Berkeley Lab have demonstrated a way to double the rate of evaporation by using solar energy and taking advantage of water's inherent properties, potentially reducing their environmental impact. The study is reported in the journal Nature Sustainability.
