Prochlorococcus and Synechococcus have evolved different adaptive mechanisms to cope with light and UV stress [PDF]

, 2012
Prochlorococcus and Synechococcus, which numerically dominate vast oceanic areas, are the two most abundant oxygenic phototrophs on Earth. Although they require solar energy for photosynthesis, excess light and associated high UV radiations can induce ...

Harmonic Generation with Single-Cycle Light Pulses

EPJ Web of Conferences, 2013
We study theoretically spatiotemporal pulse dynamics in cubic nonlinear media with instant response, nonresonant absorption and normal group velocity dispersion and reveal new features of harmonic generation when the pulse duration is reduced, including ...

Diel infection of cyanobacteria by cyanophages

Frontiers in Marine Science, 2016
Cyanobacteria exhibit biological rhythms as an adaptation to the daily light-dark (diel) cycle. Light is also crucial for bacteriophages (cyanophages) that infect cyanobacteria.

The Bamboo Flowering Cycle Sheds Light on Flowering Diversity

Frontiers in Plant Science, 2020
Bamboo is a perennial flowering plant with a distinctive life cycle: many bamboo species remain in the vegetative phase for decades, followed by mass synchronous flowering and subsequent death.

Rhodopsin gene expression regulated by the light dark cycle, light spectrum and light intensity in the dinoflagellate Prorocentrum

Frontiers in Microbiology, 2015
The proton pump rhodopsin (PPR) is widely found in marine bacteria and archaea, where it functions to capture light energy and convert it to ATP. While found in several lineages of dinoflagellates, this gene has not been studied in Prorocentrales species

Light Protection of Cycle Lanes [PDF]

International Transport Forum Discussion Papers, 2018
This report reviews the effectiveness of light separation as an alternative to more permanent infrastructure to protect cycle lanes. With more cyclists on the roads than ever, it is important to consider infrastructure options that safeguard cyclists and other road users whilst being cost effective and easily adaptable to cities that are constantly ...

Shedding light on manganese cycling in the early oceans [PDF]

Proceedings of the National Academy of Sciences, 2020
Agreement is often in short supply within the community of researchers asking questions about Earth’s earliest history. One exception, however, is the near-consensus view that oxygen (O2) was mostly absent from the atmosphere and oceans before about 2.4 to 2.3 Ga—the so-called Great Oxidation Event (GOE).

Low-cost, open-source device for simultaneously subjecting rodents to different circadian cycles of light, food, and temperature

Frontiers in Physiology
Exposure of experimental rodents to controlled cycles of light, food, and temperature is important when investigating alterations in circadian cycles that profoundly influence health and disease. However, applying such stimuli simultaneously is difficult

Light‐Controlled Cell‐Cycle Arrest and Apoptosis [PDF]

Angewandte Chemie, 2020
AbstractCell‐cycle interference by small molecules has widely been used to study fundamental biological mechanisms and to treat a great variety of diseases, most notably cancer. However, at present only limited possibilities exist for spatio‐temporal control of the cell cycle. Here we report on a photocaging strategy to reversibly arrest the cell cycle
