Physics writer Emily Conover joined Science News in 2016. She has a Ph.D. in physics from the University of Chicago, where she studied the weird ways of neutrinos, tiny elementary particles that can zip straight through the Earth. She got her first taste of science writing as a AAAS Mass Media Fellow for the Milwaukee Journal Sentinel. She has previously written for Science Magazine and the American Physical Society. She is a two-time winner of the D.C. Science Writers’ Association Newsbrief award.

All Stories by Emily Conover

  1. a central component of the Lead Radius Experiment
    Particle Physics

    The thickness of lead’s neutron ‘skin’ has been precisely measured

    At 0.28 trillionths of a millimeter thick, the shell of neutrons around the nucleus of an atom of lead is a bit thicker than physicists had predicted.

  2. scientists working on the KATRIN experiment
    Particle Physics

    The already tiny neutrino’s maximum possible mass has shrunk even further

    At less than an electron volt, neutrinos are by far the most lightweight massive particles known, a new measurement confirms.

  3. illustration of a neutron star as a bright orb on a black background
    Astronomy

    Neutron stars may not be as squishy as some scientists thought

    NASA’s NICER X-ray telescope finds that the most massive known neutron star has an unexpectedly large diameter.

  4. black and white image of Calder Hall power plant smokestacks
    Particle Physics

    How matter’s hidden complexity unleashed the power of nuclear physics

    In the last century, physicists learned to split atomic nuclei and revealed a complex world of fundamental particles.

  5. inside of the g-2 experiment at Fermilab
    Particle Physics

    Muon magnetism could hint at a breakdown of physics’ standard model

    After two decades, a new measurement of the muon magnetic anomaly reinforces earlier hints that its value disagrees with standard physics.

  6. remnant of a 1a supernova
    Physics

    Uranium ‘snowflakes’ could set off thermonuclear explosions of dead stars

    Uranium crystals that settle in the cores of white dwarfs could trigger nuclear chain reactions that blow the dead stars apart, a new study suggests.

  7. image of the big dipper constellation in the sky
    Astronomy

    Here’s why humans chose particular groups of stars as constellations

    Distances between stars, their brightnesses and patterns of human eye movement explain why particular sets of stars tend to be grouped together.

  8. a ytterbium atomic clock in a NIST lab
    Physics

    Atomic clocks take a step toward redefining the second

    Measurements of the clocks’ frequencies provide the most precise clock comparisons yet, with uncertainties less than a quadrillionth of a percent.

  9. atoms of a high-temperature superconductor
    Physics

    Can room-temperature superconductors work without extreme pressure?

    The next generation of materials that conduct electricity with no resistance could shrug off the need for high pressure and low temperatures.

  10. gold sphere experiment set up
    Physics

    A tiny gold ball is the smallest object to have its gravity measured

    A gold sphere with a mass of about 90 milligrams pulled on another sphere in accordance with Newton’s law of universal gravitation.

  11. EHT black hole image
    Physics

    Black hole visionaries push the boundaries of knowledge in a new film

    ‘Black Holes: The Edge of All We Know’ follows researchers with the Event Horizon Telescope and other physicists working to understand black holes.

  12. quarks and antiquarks inside a proton
    Particle Physics

    Protons’ antimatter is even more lopsided than we thought

    The SeaQuest experiment finds that down antiquarks within the proton are more prevalent than up antiquarks.
