‘After the Fall’: What Rome Means for America

The new issue of the print magazine contains a story by me called “ The End of the Roman Empire Wasn’t That Bad .” The title (which, like most titles, I didn’t write) represented (like many titles) intentional overstatement-for-effect. But the point of the piece was to suggest that maybe Americans should shift the way they talked and thought about the Roman Empire as a metaphor for this country.

Resistance can spread even without the use of antibiotics

Antibiotic resistance does not spread only where and when antibiotics are used in large quantities, researchers conclude from laboratory experiments. Reducing antibiotic use alone is therefore not sufficient to curtail resistance, and should be done in conjunction with measures to prevent infection with resistant germs.

Discovery of neuronal ensemble activities that is orchestrated to represent one memory

The brain stores memories through a neuronal ensemble, termed engram cells. A unique system was established to transfer neuronal population activity into light with discrimination between engram and non-engram cells using fluorescence proteins. This system revealed that engram sub-ensembles represent distinct pieces of information, which are then orchestrated to constitute an entire memory. In add

Breakdown in spawning synchrony: A silent threat to coral persistence

The impacts of human and natural disturbances on coral reefs are typically quantified through visible damage (e.g., reduced coral coverage as a result of bleaching events), but changes in environmental conditions may also cause damage in less visible ways. Despite the current paradigm, which suggests consistent, highly synchronized spawning events, corals that reproduce by broadcast spawning are

A measurement of the atomic hydrogen Lamb shift and the proton charge radius

The surprising discrepancy between results from different methods for measuring the proton charge radius is referred to as the proton radius puzzle. In particular, measurements using electrons seem to lead to a different radius compared with those using muons. Here, a direct measurement of the n = 2 Lamb shift of atomic hydrogen is presented. Our measurement determines the proton radius to be r p

Radio emission from a pulsars magnetic pole revealed by general relativity

Binary pulsars are affected by general relativity (GR), causing the spin axis of each pulsar to precess. We present polarimetric radio observations of the pulsar PSR J1906+0746 that demonstrate the validity of the geometrical model of pulsar polarization. We reconstruct the (sky-projected) polarization emission map over the pulsar’s magnetic pole and predict the disappearance of the detectable em

This platform is independent of the complex optical components or cavities that tend to con

Synthesis and observation of non-Abelian gauge fields in real space

Particles placed inside an Abelian (commutative) gauge field can acquire different phases when traveling along the same path in opposite directions, as is evident from the Aharonov-Bohm effect. Such behaviors can get significantly enriched for a non-Abelian gauge field, where even the ordering of different paths cannot be switched. So far, real-space realizations of gauge fields have been limited
