Polar ice cores and historical records evidence a large-magnitude volcanic eruption in 1831 CE. This event was estimated to have injected ~13 Tg of sulfur (S) into the stratosphere which produced various atmospheric optical phenomena and led to Northern Hemisphere climate cooling of ~1 °C. The source of this volcanic event remains enigmatic, though one hypothesis has linked it to a modest phreatomagmatic eruption of Ferdinandea in the Strait of Sicily, which may have emitted additional S through magma-crust interactions with evaporite rocks.

Determining how children solve arithmetic problems when they stop using their fingers is a real challenge. To take it up, the evolution of problem-size effects for tie and non-tie problems was observed when 6-year-olds (N = 65) shift from finger counting to mental strategies. These observations revealed that the problem-size effect remained the same for non-tie problems, whereas it drastically decreased for tie problems.

Games and analogies can significantly enrich the learning experience when integrated with traditional expository teaching methods. With this aim, we developed The Mystery of the Cell Kingdom, an online game designed to enhance understanding of the physiology of thyroid hormones through a medieval analogy. In the game, students are challenged to apply their knowledge of endocrine physiology to solve a series of relevant questions on the topic.

Bacteriophages are viruses infecting bacteria. The vast majority of them bear a tail, allowing host recognition, cell wall perforation, and DNA injection into the host cytoplasm. Using electron cryo-microscopy (cryo-EM) and single particle analysis, we determined the organization of the tail proximal extremity of siphophage T5 that possesses a long flexible tail and solved the structure of its tail terminator protein p142 (TrP).
