How a Bacterial Virulence Factor Promotes Its Own Secretion

Sep. 18, 2016 — Many bacteria depend on their ability to attach, or adhere, to our cells for the ability to cause disease. When their survival means disease for us, we often turn to antibiotics, but his miracle ... read more

Sep. 1, 2016 — Oxygen inhibits hydrogenases, a group of enzymes that are able to produce and split hydrogen. This degradation is fatal for possible biotechnological applications of these enzymes for the production ... read more

Aug. 10, 2016 — Methane seeps have strong effects on the community structure at the bottom of the Arctic ... read more

Aug. 5, 2016 — New research has found that bacteria are able to pump electrons, or "energy" directly into solid, conductive magnetic minerals which can potentially be used for long range transport ... read more

Looking Back Into the Future: Are Corals Able to Resist a Declining pH?

Aug. 4, 2016 — Tropical Porites corals adjust their internal pH to enable themselves to form calcium carbonate and grow under elevated carbon dioxide concentrations -- even for a longer period of time. In order to ... read more

Aug. 3, 2016 — Scientists have revealed how a tiny Arctic microbe, crucial to shaping the surface of glaciers, survives in such extreme ... read more

Aug. 1, 2016 — New research has found methylmercury -- a potent neurotoxin - in sea ice in the Southern Ocean. The results are the first to show that sea-ice bacteria can change mercury into methylmercury, a more ... read more

July 22, 2016 — With increasing water temperatures comes an increasing likelihood of potentially pathogenic bacteria appearing in the North and Baltic Seas. Scientists have now demonstrated that a group of such ... read more

A 'Smart Dress' for Oil-Degrading Bacteria

July 22, 2016 — The modified polyelectrolyte-magnetite nanocoating was applied to functionalize the cell walls of oil decomposing bacteria Alcanivorax ... read more

Temperature Helps Drive the Emergence of Different Personalities in Spiders

July 21, 2016 — Not a single aggressive spider was able to reproduce at 93 degrees Fahrenheit and most of them died at that temperature. But when researchers added docile spiders to the mix, the aggressive spiders ... read more

July 19, 2016 — New light has been shed on a common but poorly understood bacteria known to live in low-oxygen areas in the ocean. By culturing and sequencing the microbe's entire genome, the oceanographers ... read more

July 13, 2016 — A new study helps explain the collective dynamics that emerge when bacteria are confined to tight spaces. According to the scientists, when bacteria are confined in millimeter-sized, fluid-filled ... read more

Life at the Extremes

July 13, 2016 — In a new study, researchers from Italy examine the genes and proteins behind this organism's remarkable ability to cope with its extreme environment, which is not only unthinkably cold, but also ... read more

July 12, 2016 — Algae that live in and under the sea ice play a much greater role for the Arctic food web than previously assumed. In a new study, biologists show that not only animals that live directly under the ... read more

July 1, 2016 — Normally harmless bacteria can cause bleaching disease in seaweeds when the "trees of the ocean" become stressed by high water temperatures, researchers have discovered. Understanding these ... read more

June 30, 2016 — Researchers have described a new genus and species of cavefish from Mexico -- the Oaxaca Cave ... read more

Mountaineering Ants Use Body Heat to Warm Nests

June 29, 2016 — Underground army ants can keep their nests -- called bivouacs -- warm with their body heat; this social warming may enable fragile offspring to survive in chilly mountain forests, according to ... read more

June 28, 2016 — Researchers used a recently refined technique to identify both individual active cells, and single clusters of active bacteria and archaea within microbial communities. Scientists are interested in ... read more

Cross-Respiration Between Oral Bacteria Leads to Worse Infections

June 28, 2016 — Researchers determined that two bacterial species commonly found in the human mouth and in abscesses, cooperate to make the pathogenic bacterium, Aggregatibacter actinomycetemcomitans, more ... read more

June 28, 2016 — This cave planthopper species new to science is only the second dwelling exclusively in the subterranean depths of Brazil from its family. Surviving without seeing the light of the day at any point ... read more
