'''Natalia V. Udaltsova''' is a Russian researcher associated with the Institute of Theoretical and Experimental Biophysics of the Russian Academy of Sciences in Pushchino. She is a long-time collaborator of Simon E. Shnoll and a co-author of studies on the "macroscopic fluctuations" phenomenon. She is listed in ''[[The Worldwide List of Dissident Scientists]]''.

==Work==
Udaltsova co-authored a series of papers reporting that the fine structure of histograms built from repeated physical, chemical, and radioactive-decay measurements is not random but appears to change with characteristic cosmophysical periods. The Worldwide List cites the paper "Experiments with rotating collimators cutting out pencil of alpha-particles at radioactive decay of Pu-239 evidence sharp anisotropy of space" (2005), in which she and colleagues report that the shape of alpha-activity histograms depends on the direction in which the emitted particles travel.

The authors interpret these results as evidence of a "sharp anisotropy of space" linked to the daily rotation of the Earth and the positions of the Sun and Moon. These conclusions lie outside the accepted scientific mainstream, which regards such histogram patterns as consistent with statistical variation and measurement artifacts.
