Mighty diatoms: Global climate feedback from microscopic algae
Tiny creatures at the bottom of the food chain called diatoms suck up nearly a quarter of the atmosphere's carbon dioxide, yet research by Michigan State University scientists suggests they could become less able to "sequester" that greenhouse gas as the climate warms. The microscopic algae are a major component of plankton living in... view more... (2009-03-18)
Climate change threatens Lake Baikal's unique biota
Siberia's Lake Baikal, the world's largest and most biologically diverse lake, faces the prospect of severe ecological disruption as a result of climate change, according to an analysis by a joint US-Russian team in the May issue of BioScience. view more (2009-05-01)
Diatoms discovered to remove phosphorus from oceans
Scientists at the Georgia Institute of Technology have discovered a new way that phosphorus is naturally removed from the oceans -- its stored in diatoms. The discovery opens up a new realm of research into an element that's used for reproduction, energy storage and structural materials in every organism. The research appears in the May 2, 2008,... view more... (2008-05-05)
Controlling algal blooms
Diatoms, highly successful photosynthetic plankton responsible for 40% of the net primary production in the oceans, undergo seasonal population explosions called phytoplankton blooms that attract billions of krill, copepods, and other grazing predators. view more (2006-02-21)
Ecologists, material scientists pursue genetics of diatom's elegant, etched casing
Diatoms - some of which are so tiny that 30 can fit across the width of a human hair - are so numerous that they are among the key organisms taking the greenhouse gas carbon dioxide out of the Earth's atmosphere. view more (2008-01-24)
Chemical Cudgel in Plants
Defense mechanisms of single-celled algae Plankton are at the bottom of the food chain in all natural bodies of water and are thus correspondingly important for their ecological balance. In the cycle of eating and being eaten it isn't only fish and whales that prey on these tiny animals and plants - they also eat each other. For example, a variety... view more... (2000-11-29)
New species of diatom discovered
In the latest issue of Diatom Research, the scientists describe a new species of diatom, Hannaea superiorensis, found primarily in Lake Superior view more (2005-12-05)
Scientists learning to create nanomaterials based on micro-algae patterns
Researchers at the Georgia Institute of Technology have developed a technique to study how unicellular micro-algae, known as diatoms, create their complex cell walls. Researchers hope to learn how diatoms assemble these nanometer-patterned, intricate micro-architectures to find better methods for creating nanomaterials in the laboratory. view more (2006-12-07)
Decline of carbon dioxide-gobbling plankton coincided with ancient global cooling
The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. view more (2009-01-09)
In diatom, scientists find genes that may level engineering hurdle
Denizens of oceans, lakes and even wet soil, diatoms are unicellular algae that encase themselves in intricately patterned, glass-like shells. Curiously, these tiny phytoplankton could be harboring the next big breakthrough in computer chips. view more (2008-01-22)
Greenhouse ocean may downsize fish
By 2100, warmer oceans with more carbon dioxide may no longer sustain 1 of the world's most productive fisheries, says USC marine ecologist. view more (2008-01-14)
Decoded gene sequence of the diatom Thalassiosira pseudonana
For the very first time, the genetic make-up of a planktonic marine alga has been sequenced. During this process, a team of international scientists found unexpected metabolic pathways in the diatom Thalassiosira pseudonana. The results will be published in the scientific journal 'Science' this week. view more (2004-10-01)
Nitrogen fixation and phytoplankton blooms in the southwest Indian Ocean
Observations made by Southampton scientists help understand the massive blooms of microscopic marine algae - phytoplankton - in the seas around Madagascar and its effect on the biogeochemistry of the southwest Indian Ocean. view more (2009-08-17)
Beautiful diatoms: pattern for stable construction
AWI publication in 'Nature' Scientists from the Alfred Wegener Institute (AWI) published new results concerning the structure and material properties of diatoms in the science journal "Nature" on 20th february 2003 (Nature 421: 841-843). These single-celled marine algae are responsible for the majority of oxygen and biomass production in the... view more... (2003-02-21)
B12 Is Also an Essential Vitamin for Marine Life
B12 - an essential vitamin for land-dwelling animals, including humans - also turns out to be an essential ingredient for growing marine plants that are critical to the ocean food web and Earth's climate, scientists have found. view more (2007-05-21)
