Helen Czerski on the fun of physics

University College London physicist Helen Czerski studies the properties of the bubbles that form in the ocean, including their optics, acoustics, and influence on the surrounding atmosphere. BBC viewers will recognize her as the host of several science programs, most … Continue reading

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what you’re looking at. Some photons reflect off, reaching your eyes. Others get … Continue reading

A watershed moment in understanding how H2O conducts electricity

Scientists have taken spectroscopic snapshots of nature’s most mysterious relay race: the passage of extra protons from one water molecule to another during conductivity. The finding represents a major benchmark in our knowledge of how water conducts a positive electrical … Continue reading

Quantum physics offers new way to factor numbers

Any number can, in theory, be written as the product of prime numbers. For small numbers, this is easy (for example, the prime factors of 12 are 2, 2, and 3), but for large numbers, prime factorization becomes extremely difficult—so … Continue reading

The speed of light might have outpaced gravity in the early days of the Universe

The speed of light in a vacuum, or c, is pretty much the most fundamental constant in physics – and according to the general theory of relativity, gravity travels at the same rate. But a new study suggests that the … Continue reading

The universe is expanding at an accelerating rate—or is it?

Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery, in the late 1990s, that the universe is expanding at an accelerating pace. Their conclusions were based on analysis of Type Ia supernovae – … Continue reading

Consciousness Is the Key to Understanding Reality

In order to understand the true nature of reality, science must first recognize the importance of consciousness, says Dr. Robert Lanza, a stem-cell biologist whose work has earned him high acclaim. He also sees a greater role for consciousness in … Continue reading

For first time, researchers see individual atoms keep away from each other or bunch up as pairs

If you bottle up a gas and try to image its atoms using today’s most powerful microscopes, you will see little more than a shadowy blur. Atoms zip around at lightning speeds and are difficult to pin down at ambient … Continue reading

Quantum mechanics technique allows for pushing past ‘Rayleigh’s curse’

A team of researchers with the National University of Singapore has found a way to get around what they describe as ‘Rayleigh’s curse’—a phenomenon that happens when two light sources appear to coalesce as they grow closer together, limiting the … Continue reading

This new equation might finally unite the two biggest theories in physics

One of the most stubborn problems in physics today is the fact that our two best theories to explain the Universe – general relativity and quantum mechanics – function perfectly well on their own, but as soon as you try … Continue reading

A physicist has a new hypothesis to explain the LHC’s mysterious results

Since March, physicists around the world have been getting cautiously excited about a series of strange flashes of energy detected by CERN’s Large Hadron Collider (LHC). Nothing is verified, but the results suggest that we’re on the verge of finding the … Continue reading

Physicists have discovered what looks like an entire family of new particles in the LHC

Physicists working with the Large Hadron Collider beauty experiment (LHCb) have discovered what appears to be an entire family of new particles that our current physics models can’t explain. The existence of these new forms of matter, known as tetraquarks, challenges … Continue reading
