    A near-Earth asteroid named Kamo`oalewa could be a fragment of our moon, according to a new paper published in Nature Communications Earth and Environment by a team of astronomers led by the University of Arizona.

    Kamooalewa is a quasi-satellite -- a subcategory of near-Earth asteroids that orbit the sun but remain relatively close to Earth. Little is known about these objects because they are faint and difficult to observe. Kamooalewa was discovered by the PanSTARRS telescope in Hawaii in 2016, and the name — found in a Hawaiian creation chant — alludes to an...

    Compound provides innovative Pain Relief

    Researchers targeted a common sodium ion channel to reverse pain, with positive results that could lead to a non-addictive solution to treat pain. Researchers at the University of Arizona Health Sciences are closer to developing a safe and effective non-opioid pain reliever after a study showed that a new compound they created reduces the sensation of pain by regulating a biological channel linked to pain.

    Most people experience pain at some point in their lives, and the...

    First Quantum Simulation of Baryons

    November 12, 2021, Categories  Physics, Technology/Electronics

    A team of researchers led by an Institute for Quantum Computing (IQC) facu11lty member performed the first-ever simulation of baryons — fundamental quantum particles — on a quantum computer.

    With their results, the team has taken a step towards more complex quantum simulations that will allow scientists to study neutron stars, learn more about the earliest moments of the universe, and realize the revolutionary potential of quantum computers.

    “This is an important step forward — it is the first simulation of baryons on a quantum computer ever,” Christine Muschik, an IQC faculty member, said. “Instead of smashing particles in an accelerator, a quantum computer may one day allow us to simulate these interactions that we use to study the origins of the universe and so much more.”

    Black Hole found Hiding in Star Cluster Outside Our Galaxy

    Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have discovered a small black hole outside the Milky Way by looking at how it influences the motion of a star in its close vicinity. This is the first time this detection method has been used to reveal the presence of a black hole outside of our galaxy. The method could be key to unveiling hidden black holes in the Milky Way and nearby galaxies, and to help shed light on how these mysterious objects form and evolve.
