Algae

Spotted salamanders are unique among vertebrates, in that they're the only ones whose embryos have an algae living inside them. Scientists are now hoping that a better understanding of this symbiotic relationship could lead to new drugs for humans.
-
In order to purify wastewater, chemicals and UV light are commonly used. According to a new study, however, algae may be a more eco-friendly and energy-efficient alternative, resulting in water that's clean enough for use in aquaculture.
-
When ingested, nutrient-rich spirulina blue-green algae is claimed to offer antioxidant, immune-boosting and cholesterol-lowering effects. And while it's typically consumed in powdered form, the Bloom system lets you grow the stuff in your kitchen.
-
Along with its present use in biofuels and fertilizer, algae could potentially be utilized in applications ranging from bioprinted tissue to honeybee feed. That's why a new system is important, as it continuously checks that algae crops are healthy.
-
A new sponge-like material likened to a Swiss Army knife could help scientists tackle the problem of phosphate pollution and algae blooms, with the ability to not just capture phosphate from water sources but allow it to be collected for reuse.
-
Algae plays an important role in removing carbon dioxide from the atmosphere, and a first-of-a-kind research expedition is set to highlight just how important that role might be by studying the density of dead algae at various depths.
-
A team of researchers has made a discovery that could help our clean energy efforts along, demonstrating how algal cells can be turned into tiny hydrogen-producing factories by immersing them in sugary droplets.
-
One of the challenges in 3D printing biological tissue lies in the fact that the cells may die before oxygen-delivering blood vessels grow into the material. Harvard scientists are addressing that issue, by adding algae to the mix.
-
Many people take Spirulina as a dietary supplement, but researchers at the Swiss Federal Laboratories for Material Science have found a way to put the tiny spirals to work removing contaminants from water, and then make biofuels from their remains.
-
As factors such as habitat loss decrease the number of flowering plants in the environment, beekeepers are starting to augment their insects' diet with artificial feeds. It now turns out that microalgae may be a particularly good form of "bee chow."
-
Corals serve as a host to algae, which produces sugars that the corals consume. Now, scientists have 3D-printed coral that's even more algae-friendly than its natural equivalent – it could help limit coral bleaching, and provide a source of biofuel.

If someone is showing symptoms that may be caused by a toxic algae bloom, it's important to know ASAP if that is indeed the culprit. A new urine test could soon help in doing so.
