Physicists Use Cold Atoms to Probe Dark Energy

A team of physicists reproduced the low-density conditions of space to precisely measure dark energy, helping to reveal how strongly dark energy interacts with normal matter. Besides the atoms that make up our bodies and all of the objects we encounter in everyday life, the universe also contains mysterious dark matter and dark energy. The […]

Experiments Reveal No Difference in Mass of Proton and Antiproton

The most precise experiments ever to compare the mass of the proton and antiproton reveal no difference between the particles, determining that the masses of the proton and antiproton are identical to eleven decimal places. The existence of our world is anything but self-evident. The Big Bang created matter and antimatter in equal measure. Why […]

New Research is Helping to Bring Fusion Power Closer to Reality

Advances in magnet technology have enabled MIT scientists to propose a new design for a practical compact tokamak fusion reactor. It’s an old joke that many fusion scientists have grown tired of hearing: Practical nuclear fusion power plants are just 30 years away — and always will be. But now, finally, the joke may no […]

Physicists Create a Superfluid Gas

Physicists from MIT have created a superfluid gas, the so-called Bose-Einstein condensate, for the first time in an extremely high magnetic field. The magnetic field is a synthetic magnetic field, generated using laser beams, and is 100 times stronger than that of the world’s strongest magnets. Within this magnetic field, the researchers could keep a […]

Weyl Point Confirmed by Direct Observation for the First Time

An international team of physicists has confirmed for the first time the experimental observation of Weyl points. Part of a 1929 prediction by physicist Hermann Weyl — of a kind of massless particle that features a singular point in its energy spectrum called the “Weyl point” — has finally been confirmed by direct observation for […]

Solving the Mysteries of Conductivity in Polymers

In a newly published study scientists from MIT and Brookhaven National Laboratory reveal how electrical charge carriers move in conjugated polymers, potentially opening up further research on such applications. Materials known as conjugated polymers have been seen as very promising candidates for electronics applications, including capacitors, photodiodes, sensors, organic light-emitting diodes, and thermoelectric devices. But […]

CERN’s LHCb Experiment Detects Exotic Pentaquark Particles

Physicists at CERN’s Large Hadron Collider have reported the discovery of a class of particles known as pentaquarks. “The pentaquark is not just any new particle,” said LHCb spokesperson Guy Wilkinson. “It represents a way to aggregate quarks, namely the fundamental constituents of ordinary protons and neutrons, in a pattern that has never been observed […]

A Closer Look at Why Puddles Stop Spreading

New research from engineers at MIT helps explain the science of why puddles stop spreading. When you spill a bit of water onto a tabletop, the puddle spreads — and then stops, leaving a well-defined area of water with a sharp boundary. There’s just one problem: The formulas scientists use to describe such a fluid […]

SLAC Reveals Ultrafast Chemistry in Motion

Researchers at the SLAC National Accelerator Laboratory used SLAC’s Linac Coherent Light Source X-ray Laser to measure atomic-scale details of how ring-shaped gas molecules break open and unravel. Scientists for the first time tracked ultrafast structural changes, captured in quadrillionths-of-a-second steps, as ring-shaped gas molecules burst open and unraveled. Ring-shaped molecules are abundant in biochemistry […]

Astronomers Use Cosmic Gravity to Create "Black Hole Telescope"

Astronomers used the magnifying effect of the stars to ‘zoom in’ on galaxy PKS 1830-211, revealing very small structures in the distant galaxy. The Integral, Fermi and Swift space observatories have used the magnifying power of a cosmic lens to explore the inner regions of a supermassive black hole. Gamma rays are highly energetic radiation […]

Scientists Create Ultracold Molecules

A team of physicists from MIT has successfully cooled molecules in a gas of sodium potassium (NaK) to a temperature of 500 nanokelvins, creating ultracold molecules. The air around us is a chaotic superhighway of molecules whizzing through space and constantly colliding with each other at speeds of hundreds of miles per hour. Such erratic […]

A Computer That Operates on Water Droplets

Researchers at Stanford University have developed a synchronous computer that operates using the unique physics of moving water droplets. Their goal is to design a new class of computers that can precisely control and manipulate physical matter. Computers and water typically don’t mix, but in Manu Prakash’s lab, the two are one and the same. […]

New Technique Could Boost Development of Nanomachines

Scientists from MIT have developed a frictional interface at the atomic level. The new technique tunes friction between two surfaces, to the point where friction can vanish. Friction is all around us, working against the motion of tires on pavement, the scrawl of a pen across paper, and even the flow of proteins through the […]
