Algae

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.

When it comes to algae that produce toxins in lakes or other waterways, it's certainly best to detect excessive populations of the things as soon as possible. A new smartphone-based system could help, delivering on-the-spot readings within minutes.

Hypergiant Industries has announced an algae-fueled bioreactor that can soak up as much carbon from the atmosphere as an acre of trees.

Throughout the densely-populated country of Bangladesh, a lack of access to clean drinking water is responsible for a variety of debilitating and often-lethal infections. Soon, however, residents could filter virtually all harmful microbes out of their water, using paper derived from algae.

​Endocrine disrupting chemicals (EDCs) are mostly man-made compounds found in substances such as pesticides, food additives and personal care products. Unfortunately, they're also linked to some serious health issues. It appears that algae, however, could be used for removing them from wastewater.

Microorganisms keep turning up in Earth’s most extreme environments. To test whether certain hardy microbes can survive the harsh conditions of space or Mars, colonies were placed on the outside of the International Space Station (ISS) for almost 18 months – and many managed to survive.

In the world of palaeontology, new discoveries usually proclaim things are older than we previously thought. But new research out of the Max Planck Institute has found that animals probably arose later than is currently believed.

​When algal blooms occur in lakes, the over-abundant cyanobacteria (blue-green algae) produce a toxin known as microcystin. Now, Ohio-based scientists are using OTHER types of bacteria to neutralize that toxin, in a process that could be cheaper and more eco-friendly than the alternatives.

About 700 million years ago, basically the entire planet iced over in a period often called “Snowball Earth.” Now researchers have found fossil fats that help fill in the story of how life bounced back after this global cataclysm, and how we humans might owe our very existence to them.
