Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on those galactic neighbors, a new model suggests the Milky Way should have an additional 100 or so very faint satellite galaxies awaiting discovery.
One strategy to make biofuels more competitive is to make plants do some of the work themselves. Scientists can engineer plants to produce valuable chemical compounds, or bioproducts, as they grow. Then the bioproducts can be extracted from the plant and the remaining plant material can be converted into fuel. But one important part of this strategy has remained unclear -- exactly how much of a particular bioproduct would plants need to make in order to make the process economically feasible?
Argonne researchers have invented a machine-learning based algorithm for quantitatively characterizing material microstructure in three dimensions and in real time. This algorithm applies to most structural materials of interest to industry.
Turning a brittle oxide into a flexible membrane and stretching it on a tiny apparatus flipped it from a conducting to an insulating state and changed its magnetic properties. The technique can be used to study and design a broad range of materials for use in things like sensors and detectors.
The first detailed model of the interaction between the solar wind and the magnetic field that surrounds Mercury, findings that could lead to improved understanding of the stronger field around Earth.
Story Tips: Molding matter atom by atom and seeing inside uranium particles, from the Department of Energy's Oak Ridge National Laboratory
Scientists studying high-Tc superconductors at the U.S. Department of Energy's Brookhaven National Laboratory have definitive evidence for the existence of a state of matter known as a pair density wave--first predicted by theorists some 50 years ago. Their results show that this phase coexists with superconductivity in a well-known bismuth-based copper-oxide superconductor.
An international team of scientists has published a new study proposing an optimization methodology for designing climate-resilient energy systems and to help ensure that communities will be able to meet future energy needs given weather and climate variability. Their findings were recently published in Nature Energy.
Nuclear physicists from Argonne National Laboratory led an international physics experiment conducted at CERN that utilizes novel techniques developed at Argonne to study the nature and origin of heavy elements in the universe.
PPPL researchers find that jumbled magnetic fields in the core of fusion plasmas can cause the entire plasma discharge to suddenly collapse.
A new study by scientists at Berkeley Lab, UC Berkeley, and the University of Michigan - published online this week in the journal Science - concludes that a possible dark matter-related explanation for a mysterious light signature in space is largely ruled out.
New research conducted in part at Brookhaven Laboratory may bring a whole new class of chemical elements into a materials science balancing act for designing alloys for aviation and other applications.
Loading single platinum atoms on titanium dioxide promotes the conversion of a plant derivative into a potential biofuel.
Researchers have created miniature lasers that are stable and work continuously at room temperature. The lasers use arrays of nanopillars with nanoparticles that can absorb two photons of light and emit them as a single photon with higher energy. They could have applications in quantum technologies, imaging, and other areas.
Researchers were looking into a protein that tuberculosis bacteria need to thrive, but when they finally solved its structure, they discovered a gigantic cavity that could help shuttle a variety of molecules into TB bacteria.

A new design has put the long-sought idea of artificial photosynthesis within reach
An advance in molecular moviemaking reveals the subtle, complex ways a simple molecule can shimmy and fly apart
Researchers observed atomic nuclei moving over distances of less than an angstrom in less than a trillionth of a second -- a level of resolution that can only be achieved with an X-ray free-electron laser.
Research led by a Princeton University graduate student demonstrates that machine learning can predict and avoid damaging disruptions to fusion facilities.
Atomic distortions emerging in the electrode during operation provide a "fast lane" for the transport of lithium ions.
Permanent magnets far stronger than those on refrigerator doors could be a solution for delivering fusion energy
Permanent magnets can, in principle, greatly simplify the design and production of the complex coils of stellarator fusion facilities.
Injecting pellets of hydrogen ice rather than puffing hydrogen gas improves fusion performance. Studies by PPPL and ORNL physicists compared the two methods on the DIII-D National Fusion Facility, looking ahead to the injection fueling planned for ITER.
New results from precision particle detectors at the Relativistic Heavy Ion Collider (RHIC) offer a fresh glimpse of the particle interactions that take place in the cores of neutron stars and give nuclear physicists a new way to search for violations of fundamental symmetries in the universe.
A forthcoming N = 126 Factory will investigate one of the great questions in physics and chemistry: how were the heavy elements from iron to uranium created?
Researchers from the Department of Energy's SLAC National Accelerator Laboratory have made a promising new advance for the lab's high-speed "electron camera" that could allow them to "film" tiny, ultrafast motions of protons and electrons in chemical reactions that have never been seen before.
