NewsMarine algae use unique pigment to shield photosynthesis from excess light
Researchers have discovered that marine algae have evolved unique pigments not only to capture the green-blue light available underwater but also to enhance their resilience against excessive sunlight.

NewsAlgae and water fleas in lakes: Light color influences food webs
Phytoplankton are the basic food source for many aquatic organisms. A new study shows that the light spectrum is more important for these microalgae and for lake ecosystems than previously assumed.

NewsScientists discover regulatory pathway behind cyanobacteria’s carbon-fixing factories
A new study illuminates a key regulatory pathway between cyanobacteria’s light-harvesting systems and the inner compartments where carbon fixation happens, helping us to understand how cyanobacteria balance their energy demands.

NewsResearchers uncover a unique light-harvesting structure in marine algae
Scientists conducted a high-resolution analysis of a photosynthetic complex found in a marine alga, Chrysotila roscoffensis. The photosystem II–FCPII complex could shape the future of artificial photosynthesis.

NewsCool science: Researchers craft tiny biological tools using frozen ethanol
Imagine drawing on something as delicate as a living cell — without damaging it. Researchers have made this groundbreaking discovery using an unexpected combination of tools: frozen ethanol, electron beams and purple-tinted microbes.

NewsBiochemists discover self-repair function in key photosynthetic protein complex
Receiving too much light can damage the photosystem II protein complex shared by lineages of cyanobacteria, algae and land plants and erode the photosynthetic efficiency of plants. Biochemists have gleaned new details about how photosystem II repairs itself.

NewsStudy yields evidence of oldest confirmed photosymbiosis in corals
Researchers have demonstrated, using nitrogen isotope analyses, that some extinct corals from the Middle Devonian period were already symbiotic. This represents geochemical evidence of the oldest confirmed photosymbiosis in corals.

NewsScientists identify potential microbial habitats in Martian ice
Dusty ice exposed at the surface of Mars could provide the conditions necessary for the presence of photosynthetic life, according to a modelling study.

NewsAlgae offer real potential as a renewable electricity source
Researchers have described extracting energy from the photosynthesis process of algae suspended in a specialized solution and housed in small power cells that can generate enough energy to power low- and ultra-low power devices.

NewsRegenerating worms have genetic control over their algal partners
Researchers have found that when Convolutriloba longifissura, a species of acoel that hosts the symbiotic algae Tetraselmis, regenerates, a genetic factor that takes part in the acoel regeneration also controls how the algae inside of them reacts.

NewsFor microscopic organisms, ocean currents act as ‘expressway’ to deeper depths
New research shows how tiny plant-like organisms hitch a ride on ocean currents to reach darker and deeper depths, where they impact carbon cycling and microbial dynamics in the subtropical oceans.

NewsStudy reveals convergent evolution of algal CO2-fixing organelles
Various pyrenoid-associated proteins have been reported among the algae studied, suggesting that CO2-fixing organelles evolved independently in each algal group.
-
NewsResearchers shine light into the darkness of photosynthesis
Researchers have now succeeded for the first time in visualising the copying machine of chloroplasts, the RNA polymerase PEP, in high-resolution 3D.

NewsOldest thylakoids in fossil cyanobacteria uncover evolution of photosynthesis
Researchers have identified microstructures in fossil cells that are 1.75 billion years old. These structures, called thylakoid membranes, are the oldest ever discovered.
-
NewsRIPE researchers add plant protein mechanism into bacteria
A team from the Australian National University (ANU) has modified the protein folding properties of bacteria by adding multiple components from the chloroplast of plants.
-
NewsEngineered microbial community could serve as living carbon sink
A Chinese team of researchers has genetically engineered a microbial community which could serve as a living carbon sink.

NewsMarine bacteria take in carbon dioxide through photosynthesis
Researchers in China have identified carbon-dioxide-fixing cells from seawater and determined that their sample contains functioning genes for light harvesting, suggesting that the bacteria engage in photosynthesis.
