Climate change disrupts Arabian Sea with little-known, voracious plankton

Dead zones, or marine areas with levels of dissolved oxygen so low few things can exist, are becoming increasingly common as climate changes and soaring pollution from human populations combine to put record stress on waterways. This trend is alarming in most places, because marine life Continue reading Climate change disrupts Arabian Sea with little-known, voracious plankton

Secretive Victorian Artists Made These Intricate Patterns Out of Diatom

Since seeing his first diatom arrangement—an intricate pattern of algae crafted by German microscopist J.D. Möller—Matthew Killip has been enthralled with the Victorian art form. “I love seeing the hand of man display the work of nature so beautifully,” he says. Continue reading Secretive Victorian Artists Made These Intricate Patterns Out of Diatom

Solving the Blue-Green Algae Problem: Mechanical Circulation as a Way to Win the Algae Battle

MINNEAPOLIS, MN–(Marketwired – September 17, 2014) – Harmful blue-green algae blooms (HABs) in lakes have made headlines this summer throughout the country. HABs can disrupt municipal potable water systems, forcing residents to rely on bottled water, Continue reading Solving the Blue-Green Algae Problem: Mechanical Circulation as a Way to Win the Algae Battle

Intricate algae produce low-cost biosensors

(Phys.org) —Oregon State University researchers are combining diatoms, a type of single-celled photosynthetic algae, with nanoparticles to create a sensor capable of detecting miniscule amounts of protein or other biomarkers.

This is a new and innovative approach to optical biosensors, which are important in health care for such applications as… Continue reading Intricate algae produce low-cost biosensors

Deadly harvest: Toxic algae killing sea life at record levels

[12th, May 2014] First, the pelicans started falling out of the sky, flopping on their backs as soon as they landed and flailing drunkenly. Scores of brown pelicans, disoriented, sick — and dying—were winding up far away from their ocean home. Then marine mammals — mostly California sea lions — began… Continue reading Deadly harvest: Toxic algae killing sea life at record levels
