The effect of respiration on photosynthesis

The effect of respiration on photosynthesis

Scientists have long studied which of the three primary photosynthetic eukaryotes (red algae, green algae, and glaucophytes) came into existence first — to unravel the biological mystery of algae evolution by analyzing their genetic information. Despite learning that the structure of cyanelles, an organelle unique…

Resetting the circadian clock in algae

Resetting the circadian clock in algae

The human body clock runs on a 24-hour cycle, or circadian (from the Latin meaning “about a day”) rhythm. When our internal cycle gets out of sync with our surroundings, such as when crossing time zones, jetlag can result. The circadian rhythm therefore needs to be reset, which is achieved primarily…

Microalgae as a fish feed ingredient

Growing microalgae in agricultural liquid waste

Fis.com reports that, after three years of research, Embrapa Agroenergía, in Brasilia, Brazil, has identified microalgae species that can be grown in liquid waste from agroindustry processing, and that generate renewable raw material for biofuels, food and cosmetics, among other products…

1.6 Billion-year-old red algae fossils discovered

1.6 Billion-year-old red algae fossils discovered

Scientists at the Swedish Museum of Natural History have found fossils of 1.6 billion-year-old probable red algae. The spectacular finds, publishing on March 14, 2017, in the open access journal PLOS Biology, indicate that advanced multicellular life evolved much earlier than previously thought…

Enzymes and algae alternatives to synthetic chemicals

Enzymes and algae alternatives to synthetic chemicals

Elaine Ramirez writes for asia.nikkei.com that, ever since four pregnant women died of mysterious lung problems in 2011, South Korea has been haunted by scandals over toxic chemicals in common household goods. The multiple deaths, together with serious lung damage suffered by hundreds of other victims…

Sandia purposefully crashing algae ponds

Sandia purposefully crashing algae ponds

For algal biofuels to compete with petroleum, farming algae has to become less expensive. Toward that goal, Sandia National Laboratories is testing strains of algae for resistance to a host of predators and diseases, and learning to detect when an algae pond is about to crash. An estimated 30 percent of current production…

Seaweeds and human evolution

Seaweeds and human evolution

Birgitte Svennevig writes in Phys.org about, millions of years ago, early Homo sapiens branching out from the primitive hominoid family tree – possibly a crucial turn in human evolution – partly driven by seaweed and its particular content of essential nutrients. Our ancestors needed lots of energy-rich foods just…

Understanding oil production in Nannochloropsis

Understanding oil production in Nannochloropsis

Phys.org reports on research at Tokyo Institute of Technology that has identified unique lysophosphatidic acid acyltransferases as being the central enzymes for triacylglycerol synthesis by the oleaginous alga Nannochloropsis, uncovering mechanisms of biofuel production in microalgae…

On dinoflagellate algae’s symbiosis with corals

On dinoflagellate algae’s symbiosis with corals

Dinoflagellates are among the most prolific organisms on the planet, forming the basis of the oceanic food chain, and their close symbiotic relationships with corals help maintain healthy reefs. However, because dinoflagellates have unusually large genomes, very few species have been sequenced…

Algal extract repairs human cells

Algal extract repairs human cells

Wesley Tin reports for medicalnewsbulletin.com that many human diseases, such as diabetes, chronic inflammation, and various cancers, are linked to reactive oxygen species (ROS) and their harmful effects on the human body. ROS are naturally occurring and are essential in cell signaling and homeostasis…

Diatoms indicating the future

Diatoms indicating the future

Peter Rüegg writes for Phys.org that, during their rapid growth cycle, diatoms absorb huge amounts of trace elements and nutrients from the surface water layer, especially silicon to form their shells, and zinc, which plays a vital physiological role in their development. The heavy depletion of nutrients caused by the…
