The Higgs boson (blue) may be created by the interaction of gluons (yellow) during proton collisions. Protons consist of two up quarks (red) and one down quark (purple), bound by gluons so strongly that in the sea of virtual particles (gray) more massive quarks and antiquarks, for example beautiful quarks, may appear, the presence of …
A new kit the size of a paperback book radically improves the efficiency of searching for a bacteriophage that will respond to an antibiotic resistant superbug. Credit: McMaster University The great promise of bacteriophages is that they naturally destroy bacteria, often in situations where antibiotics fail. Until now, though, there has been no way to …
Credit: Pixabay/CC0 Public Domain Up to 60% of near-Earth objects could be dark comets, mysterious asteroids that orbit the sun in our solar system that likely contain or previously contained ice and could have been one route for delivering water to Earth, according to a University of Michigan study. The findings suggest that asteroids in …

The “eternal” ice in Antarctica is melting faster than previously assumed, particularly in West …
Schematic of H3+ production in Jupiter. Auroral H3+ emission near the magnetic poles is sourced by precipitating electrons, and solar extreme UV irradiates the day side and dominates H3+ production near the equator. No significant H3+ is expected at low latitudes on the night side, making it an ideal DM signal region. Credit: Physical Review …
Researchers investigated three mysterious objects in the early universe. Shown here are their color images, composited from three NIRCam filter bands onboard the James Webb Space Telescope. They are remarkably compact at red wavelengths (earning them the term “little red dots”), with some evidence for spatial structure at blue wavelengths.

This image of NASA’s Perseverance rover gathering data on the “Walhalla Glades” abrasion was taken in the “Bright Angel” region of Jezero Crater by one of the rover’s front hazard avoidance cameras on June 14. The WATSON camera on the SHERLOC instrument is closest to the Martian surface. Credit: NASA/JPL-Caltech After six months of effort, …
