Phytoplankton are tiny, plant-like organisms that live in the ocean and are, basically, at the very bottom of the food chain. But, sometimes, they get their revenge. When lots and lots and lots of phytoplankton get together, they can form what we call a "red tide," a discoloration of the water at a particular point where the plankton have become densely concentrated.
Some red tides are natural. Others happen when nutrient runoff from farm fertilizers creates a massive buffet for plankton. Some red tides can kill, as the plankton can produce toxins and their deaths reduce the oxygen content of the water. And sometimes, red tides glow in the dark.
The phytoplankton in this red tide off a California beach are bioluminescent. Their cells produce a chemical reaction that creates a soft, blue-green glow. It's basically the same thing that makes lightning bugs light. In this video by Loghan Call and Man's Best Media, you can see plankton light up in the beach (and a few surfers).

Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.

Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
