Our Paramecia Are Infected

Journey to the Microcosmos

"We recently discovered some Holospora infecting one of our Paramecium samples. How does that happen? How does the Holospora get in there? And how are they so successful at infecting?

Coronavirus vs. Humankind

via APOD/NASA

"Explanation: Humanity is under attack. The attack is not from large tentacle-flailing aliens, but from invaders so small they can barely be seen, and so strange they are not even clearly alive. All over planet Earth, the human home world, DNA-based humans are being invaded by the RNA-based SARS-CoV2. The virus, which creates a disease known as COVID-19, specializes in reprogramming human cells into zombies that manufacture and release copies of itself. Pictured here is a high magnification image of a human cell covered by attacking novel coronavirus SARS-CoV2 (orange). Epic battles where two species square off in a fight to the death are not unusual on Earth, with several just involving humans typically ongoing at any time. Even so, most humans are predicted to survive. After several years, humanity expects to win this war -- but only after millions of humans have died and trillions of coronaviruses have been destroyed."

the heart's 'brain'

via Endgadget

"Our hearts are primarily controlled by the brain and autonomic nervous system, but we also have a backup. The heart has its own mini-brain called the intracardiac nervous system (ICN), which fine tunes external autonomic signals and keeps the heart pumping smoothly. Its proper function is essential for good health and disease protection, but the problem is that scientists have a poor understanding of how it works. For the first time, researchers from Thomas Jefferson University have been able to show its structure in stunning 3D detail"

Growth Habits of the Strange & Bizarre : Giant Coreopsis, Leptosyne gigantea

Published on Mar 15, 2020 Crime Pays But Botany Doesn't

"In this episode of Crime Pays, we take you to a dune habitat full of rare plants during the initial stages of the 21st century's first pandemic. The plant community here is highlighted by a member of the sunflower family that is thought to have recolonized the mainland after emerging as a species on the Channel Islands, 80 miles away. This plant exhibits some of the many traits found on plants that evolve on relatively small islands - seeds with reduced dispersal potential (in this case a tiny pappus) and enlarged size and habit compared to other species in the genus."

Bioluminescent waves in San Diego, Red Tide Blue Waves

Published on Feb 10, 2014 Peter Kragh

"When conditions are right (or wrong) the algea off the coast blooms and can create Red Tides. When the algea gets excited by the movement of the wave it triggers the bioluminescence, a defense response. The more algea the more light.
This was shot mainly in Del Mar and Solana Beach.
In 15 years, I've only seen it once like this.
