Researchers at IBM create triangulene, a magnetized molecule with unknown potential

IBM scientists use microscopy methods to create an “impossible” carbon molecule, triangulene. Triangulene is made of 6 carbon rings with two unpaired electrons roaming about. While triangulene has not been fully characterized at this point, the unpaired electrons have aligned spin, making this molecule a prime candidate for applications in quantum computing and other fields.

The AMS Experiment on the International Space Station

New Physics from the AMS Experiment – Particle Physics on the International Space Station

In 2011 the Alpha Magnetic Spectrometer, or AMS, was launched into space. AMS, housed by the International Space Station and led by a Nobel Prize winning principle investigator, is commonly referred to as the most sophisticated particle physics experiment in space. The experiment was designed to study cosmic rays, a variety of high energy particles produced in space. In five years of operation, AMS has collected … Continue reading New Physics from the AMS Experiment – Particle Physics on the International Space Station

For almost a century, galactic rotation curves have served as robust evidence for the existence of dark matter. A rotation curve is simply the radial velocity of the stars, dust, and gas that make up a galaxy plotted as a function of their distance from the galaxy’s center. Based on the gravitational pull of matter, one would expect that stars closest to the center of the galaxy would move faster than the stars near the galaxies outer edge. However, in most galaxies, inner and outer stars move at roughly the same velocity. There is some additional gravitational pull on the outer stars that isn’t fully described by the amount of visible matter in a galaxy. For ages, most scientists have interpreted this result to mean that galaxies are surrounded by a halo of invisible dark matter. However, this new finding points to several other possibilities.

Galactic Rotation Curves Revisited: A Surprise For Dark Matter

Historically, galactic rotation curves have suggested that galaxies are surrounded by a vast amount of invisible matter, otherwise known as a dark matter halo. A few weeks ago, a team of astrophysicists published a result that completely contradicts these halo models and could even change the popular understanding of dark matter. The team found that galactic rotation curves can be calculated explicitly from a simple … Continue reading Galactic Rotation Curves Revisited: A Surprise For Dark Matter

Just a Phase

The patterns seen here are called interference rings, or Newton’s rings, and are generated when light waves reflect off of two glass surfaces that are in very close proximity to each other, such as a glass microscope slide and a cover slip. Imperfections in the glass cause the waves to be reflected at different points of the wave. Where you see bright rings, two waves … Continue reading Just a Phase

LIGO and Gravitational Waves: Discovery of the Century

The Twitter rumors are true! In what some scientists are calling the discovery of the century, LIGO (Laser Interferometer Gravitational-Wave Observatory) finally announced the first direct observation of gravitational waves.   Until a few days ago, gravitational waves were the only untested prediction of General Relativity. In General Relativity, space and time are not fixed. Spacetime curves around the matter and energy in the universe, … Continue reading LIGO and Gravitational Waves: Discovery of the Century

The Physics of Football

Every year, the NFL makes rule changes that affect team strategy and game outcomes. Some of these rules are designed to maintain the safety of players, while others are designed to increase the competitiveness of the game. However, there is one aspect of the game that the NFL can never change: the laws of physics. In the new series by Forbes Science, “Football Physics,” Chad Orzel … Continue reading The Physics of Football

Bringing Star Trek to Life: Scientists in Spain and the UK develop “tractor beam” to manipulate particles

by Erin Dahlstrom figures by Utsarga Adhikary Popularized by films like Star Trek and Star Wars, the tractor beam is an iconic science fiction technology that allows the user to manipulate objects in space without making physical contact with the objects. While humans today may not be ready to use this technology in outer space, the ability to manipulate objects without touching them could potentially … Continue reading Bringing Star Trek to Life: Scientists in Spain and the UK develop “tractor beam” to manipulate particles
