Could we eliminate any particles from the standard model of physics?
Could we eliminate any particles from the standard model of physics?
The standard model of physics is one of the most successful scientific theories in existence, but do we need it all? Columnist Chanda Prescod-Weinstein explores whether it’s carrying any excess baggage
1 in 5 people may carry this hidden genetic heart risk
1 in 5 people may carry this hidden genetic heart risk
Very high levels of the inherited cholesterol-related particle Lp(a) were linked to a greater risk of major cardiovascular events, particularly stroke and cardiovascular death, in a study of more than 20,000 people. Since elevated Lp(a) often flies completely under the radar, a s
Using salt to drive drug-carrying particles deeper into difficult-to-treat biofilms
Using salt to drive drug-carrying particles deeper into difficult-to-treat biofilms
Biofilms—bacterial communities encased in a sticky, polymer-rich matrix—can be difficult to treat because that matrix slows antibiotics and drug-carrying particles. With help from salt, though, Yale researchers have found a way to steer these particles into some biofilms and even
Tiny particles defy action-reaction symmetry to stay in motion
Tiny particles defy action-reaction symmetry to stay in motion
From schools of fish and flocks of birds to microscopic synthetic particles, many systems in nature and the laboratory consist of individual units or agents that move by consuming energy. These systems are known as active matter because their components continuously use energy to

Dirty air may trigger painful rheumatoid arthritis flares
Tiny pollution particles from smoke, soot, and dust may worsen rheumatoid arthritis and raise the risk of painful flares, particularly after prolonged exposure. The findings suggest that avoiding poor air quality could become an important part of managing the disease.

Molecular orbitals imaged in 3D, opening path to femtosecond videos
One of the most famous and intriguing results of quantum mechanics is the finding that fundamental particles, such as electrons, cannot be pinned down to one single location. Instead, a particle is described by its "wavefunction," which allows researchers to derive probability di
Human norovirus capsid shifts between two shapes, cryo-EM reveals
Human norovirus capsid shifts between two shapes, cryo-EM reveals
A research team led by Kazuyoshi Murata has discovered that virus-like particles (VLPs) of human norovirus genotype GII.3 are not structurally rigid, but can adopt two distinct conformational states, similar to those previously reported for murine norovirus.

X(2370) emerges as glueball-dominated particle in collider experiments
At the International Conference on High Energy Physics in Brazil, the BESIII Collaboration report that, after 15 years of sustained research, it identified the dominant constituent of the X(2370) as a pseudoscalar glueball with spin-parity quantum numbers of 0⁻⁺.
New 'shape-shifting' architecture brings versatility to photonic quantum computing
New 'shape-shifting' architecture brings versatility to photonic quantum computing
Using light to process quantum information is one of the most promising approaches to building future quantum computers. Light particles, known as photons, are excellent carriers of quantum information, but their lack of natural interactions has created a major challenge for rese

Jesse Thaler named director of the Laboratory for Nuclear Science
The professor of physics and inaugural director of the NSF AI Institute for Artificial Intelligence and Fundamental Interactions will lead LNS and continue his research in particle physics.
Quantum fluid reveals hidden states that can be switched with a magnetic field
Quantum fluid reveals hidden states that can be switched with a magnetic field
Bose-Einstein condensates (BECs) are often described as a "fifth state of matter": a quantum state in which many particles lose their individual identities and behave as one collective object. For more than 60 years, researchers have sought to create such condensates from exciton
Swarms of tiny robots remove microplastics from soil and water
Swarms of tiny robots remove microplastics from soil and water
Microplastics, which are plastic particles under 5 millimeters, are a major and growing threat in both soil and water. They damage soil fertility, disrupt nutrient cycling, harm aquatic and terrestrial life, and can move through the food chain. That makes cleaning them up an urge
