Young Children's Epistemic Operations and Emergent Argumentation in Inquiry‐Based Discussions: The Role of Teacher Questioning and Collaborative Interactions

open access: yesJournal of Research in Science Teaching, Volume 62, Issue 9, Page 2060-2079, November 2025.
ABSTRACT Promoting argumentation based on evidence allows students to give meaning to the phenomena observed, enabling the construction of knowledge. Children's argumentative discourse can be activated by appropriate instruction, but there is little information on argumentation at early ages and there is a need for the teacher to understand how to ...

The Light Growth Response of Phycomyces [PDF]

open access: yes, 1973
With the help of an automated tracking system we have studied the characteristics of the transient light growth response of Phycomyces. The response shows a sharply defined latency. The Q10 of the reciprocal latency is 2.4. Response patterns at different

ON "REVERSAL" OF PHOTOTROPISM IN PHYCOMYCES [PDF]

open access: yesJournal of General Physiology, 1932
Alleged reversal of the phototropism of the sporangiophores of Phycomyces by high intensities of light does not occur if infra-red radiation is properly excluded. Phototropic "indifference" alone occurs at high intensities due to equal photic action on both sides of the sporangiophore.

Is the Responsiveness to Light Related to the Differences in Stem Straightness among Populations of Pinus pinaster?

open access: yesPlants, 2019
Stem straightness is related to wood quality and yield. Although important genetic differences in stem straightness among the natural populations of Pinus pinaster are well established, the main drivers of these differences are not well known.

PHOTOTROPISM OF DIXIPPUS MOROSUS [PDF]

open access: yesJournal of General Physiology, 1928
1. Local differences in the effects of stimulation of parts of the eye by light are expressed in Dixippus morosus by differential circus movements. 2. The angle of inclination of the body axis toward one source of light when the animal is on a vertical plane with light from one side is inversely proportional to the logarithm of the ...

Microbial drivers of root plasticity

open access: yesNew Phytologist, Volume 248, Issue 1, Page 52-67, October 2025.
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Bees, flowers and UV

open access: yesPlant Biology, Volume 27, Issue 6, Page 948-961, October 2025.
Human‐invisible but bee‐visible UV patterns in flowers aid pollination by signalling to pollinators and protecting vulnerable DNA in pollen. ABSTRACT Ultraviolet light shining on flowers has various effects. In this review we assess functions of UV pigments and UV reflection patterns in flowers, including visual signalling by reflectance, fluorescence,

Two Decades of Optogenetic Tools: A Retrospective and a Look Ahead

open access: yesAdvanced Genetics, Volume 6, Issue 3, September 2025.
Optogenetics provides up to millisecond scale, cell type‐specific control of biology using light‐sensitive proteins. This review chronicles two decades of tool development, from microbial rhodopsins and photoactivated enzymes to allosteric switches, surveys broad applications in neuroscience, molecular and cell biology, cardiology, immunology, and ...
