Paleopteran molecular clock: Time drift and recent acceleration
Ecology and Evolution, Volume 14, Issue 9, September 2024.Constant evolution rates, which form the foundation of the strict molecular clock model, do not apply in the case of Paleoptera, highlighting a notable bias in the molecular clock hypothesis. The current biodiversity may be the outcome of a relatively recent, exponential increase in base substitution rates.

Modelling the ozone penetration in a grain layer / Ozono skverbties grūdų sluoksnyje modeliavimas
Journal of Environmental Engineering and Landscape Management, 2012 Studies of grain drying with ozone-air mixture were carried out to detect the ozone penetration patterns through the grain mound of various moisture content (14.6 ≤ w 0 ≤ 23.0%) at different ozone concentrations (500 ≤ C 0 ≤ 1250 ppb) in the supplied air.

Cognitive Science, Volume 48, Issue 6, June 2024.Abstract Previous research suggests that curiosity is sometimes induced by novel information one has no relevant knowledge about, but it is sometimes induced by new information about something that one is familiar with and has prior knowledge about. However, the conditions under which novelty or familiarity triggers curiosity remain unclear.

Ecology and Evolution, Volume 14, Issue 5, May 2024.Urbanization alters ecosystems and evolutionary processes. Processes like air pollution by tropospheric ozone contribute to the decline of urban and peri‐urban ecosystems, such as Abies religiosa forests in the peripheral mountains southwest of Mexico City.
