A Holographic View into Quantum Anomalies
Theorists calculated how the key ingredients of a phenomenon called the chiral magnetic effect should evolve over time in an expanding quark-gluon plasma. The theorists used the holographic principle to model the magnetic fields and other relevant characteristics needed for the effect. The results will help scientists interpret collision data and plan new searches for the chiral magnetic effect and the underlying quantum anomaly.

New study shows superior reactive oxygen species removal ability of copper coupled to lysozyme
In aerobic organisms, reactive oxygen species (ROS), such as hydroxide (OH), singlet oxygen (1O2), hydrogen peroxide (H2O2), and superoxide (O2-) ions are produced during aerobic respiration, which causes serious oxidative damage to biomolecules in the body.
Quantum scientists accurately measure power levels one trillion times lower than usual
Scientists in Finland have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures - a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.

The laws of physics have not always been symmetric. And it may explain why you exist.
The universe once preferred one set of shapes over their mirror images, a violation of parity symmetry that helps explain the abundance of matter over antimatter.
Electronic Noses Sniff Out Volatile Organic Compounds
Tracing volatile organic compounds is important for public safety and all "smell" related issues. To this end, in Applied Physics Reviews, Liu et al. introduce a fluid mechanics-based chamber design for an electronic nose that consistently detects VOCs at low concentrations. The strategy, which includes using a shuntlike device to control the behavior of fluid flow, is a step forward in e-nose technology development.

Los misteriosos anillos de Quaoar
Una ocultacion estelar reciente revelo la presencia de un segundo anillo alrededor del candidato a planeta enano denominado Quaoar. A traves del instrumento 'Alopeke del Telescopio Gemini Norte en Hawai'i, operado por NOIRLab de NSF, los astronomos detectaron pequenas fluctuaciones en la luz de la estrella, lo cual indica la presencia de un anillo que existe en un lugar bastante inusual en la orbita de Quaoar.
