Human biomass movement exceeds the biomass movement of all land animals combined Open
Earth is teeming with life on the move, shaping ecosystems and human civilizations alike. However, the magnitude of movement by humans and other animals has yet to be assessed holistically. Here we quantify the movement of biomass across a…

Reply to Santini et al.: Total population reports are necessary for global biomass estimation of wild mammals Open
Micro-nano plastics originating from the prevalent usage of plastics have raised increasingly alarming concerns worldwide. However, there remains a fundamental knowledge gap in nanoplastics because of the lack of effective analytical ...Pl…

The global biomass of wild mammals Open
Wild mammals are icons of conservation efforts, yet there is no rigorous estimate available for their overall global biomass. Biomass as a metric allows us to compare species with very different body sizes, and can serve as an indicator of…

The global biomass and number of terrestrial arthropods Open
Insects and other arthropods are central to terrestrial ecosystems. However, data are lacking regarding their global population abundance. We synthesized thousands of evaluations from around 500 sites worldwide, estimating the absolute bio…

Omicron infection enhances Delta antibody immunity in vaccinated persons Open
The extent to which Omicron infection 1–9 , with or without previous vaccination, elicits protection against the previously dominant Delta (B.1.617.2) variant is unclear. Here we measured the neutralization capacity against variants of sev…

Omicron infection of vaccinated individuals enhances neutralizing immunity against the Delta variant Open
Omicron variant (B.1.1.529) infections are rapidly expanding worldwide, often in settings where the Delta variant (B.1.617.2) was dominant. We investigated whether neutralizing immunity elicited by Omicron infection would also neutralize t…

Optical analogues of black-hole horizons Open
Hawking radiation is unlikely to be measured from a real black hole, but can be tested in laboratory analogues. It was predicted as a consequence of quantum mechanics and general relativity, but turned out to be more universal. A refractiv…

Boosting few-cycle soliton self-frequency shift using negative prechirp Open
Soliton self-frequency shifting of light pulses in fibers is used for versatile tunable light sources. Few-cycle pulses of high soliton number offer unique advantages, in particular the rate of Raman frequency shift is extremely fast. Howe…

Cherenkov radiation of light bullets Open
Electrically charged particles, moving faster than the speed of light in a\nmedium, emit Cherenkov radiation. Theory predicts electric and magnetic dipoles\nto radiate as well, with a puzzling behavior for magnetic dipoles pointing in\ntra…

Observation of Stimulated Hawking Radiation in an Optical Analogue Open
The theory of Hawking radiation can be tested in laboratory analogues of black holes. We use light pulses in nonlinear fiber optics to establish artificial event horizons. Each pulse generates a moving perturbation of the refractive index …
