NewsMarine viruses use ‘hijacked’ genes to take over bacteria and exploit their energy systems
Marine viruses deploy a sophisticated Trojan horse maneuver that enables them to dismantle the energy systems of ocean bacteria and use the breakdown products for self-replication, according to a new study.

NewsTeam discovers cyanobacteria activate different genes by day and by night
By analyzing gene expression in the cyanobacterium Nostoc punctiforme, scientists discovered that during daylight, the cells focus on metabolism. But under cover of darkness, they turn to the control of genome repair and activate various genetic elements.

NewsMystery toxic algae regime change in Salem’s drinking water source
A long-term analysis shows that a major Oregon reservoir abruptly swapped one type of toxic algae for another midway through the 12-year study period, absent any obvious cause.

NewsScientists reveal how cyanobacteria use ’sunscreen’ to adapt to climate
Using single particle spectroscopy, researchers revealed insights into how different types of photosynthetic bacteria can use a shared mechanism to protect themselves from too much sunlight.

NewsEarth’s oxygen boom: a fresh perspective for a billion-year-old problem
A new study examines nickel and urea in early microbial habitats, showing how ancient cyanobacteria adapted to their chemical surroundings. By recreating Archean conditions in the lab, researchers uncovered clues about the delicate balances that shaped early cyanobacterial life.

NewsScientists discover regulatory pathway behind cyanobacteria’s carbon-fixing factories
A new study illuminates a key regulatory pathway between cyanobacteria’s light-harvesting systems and the inner compartments where carbon fixation happens, helping us to understand how cyanobacteria balance their energy demands.

NewsDo stranded dolphins have Alzheimer’s disease - and how are cyanobacteria involved?
Scientists have come up with an unusual hypothesis: perhaps dolphins become disoriented by suffering from a form of Alzheimer’s disease. It appears that Alzheimer’s-type neuropathology and disorientation may result from chronic exposure to toxic molecules produced by cyanobacteria.

NewsOcean warming puts vital marine microbe Prochlorococcus at risk
A new study finds that Prochlorococcus prefers ocean water between 66 and 86 degrees and doesn’t tolerate water much warmer. Climate models predict that subtropical and tropical ocean temperatures will exceed that threshold in the next 75 years.

NewsTiny ocean partnership between algae and bacteria reveals secrets of evolution
The microscopic alliance between algae and bacteria offers rare, step-by-step snapshots of how bacteria lose genes and adapt to increasing host dependence, a new study shows.

NewsUnicellular cyanobacterium UCYN-B significantly contributes to global oceanic nitrogen fixation
Researchers report that the cyanobacterium UCYN-B drives high N2 fixation rates in previously unrecognized hotspots accross the global ocean, making a significant contribution to the ocean’s nitrogen supply and productivity.

NewsTiny artificial cells can keep time, study finds
A team of researchers has shown that tiny artificial cells can accurately keep time, mimicking the daily rhythms found in living organisms like cyanobacteria. Their findings shed light on how biological clocks stay on schedule despite the inherent molecular noise inside cells.

NewsDecoding the blue: Advanced technology realizes potential in harmful algal bloom monitoring
Researchers have developed a powerful new method to detect harmful blue-green algae in freshwater lakes. Their method can identify toxin producing blue-green algae before they become damaging in recreational waters and pose threat to public health.
-
NewsHarmful algae blooms have secret to success over other algaes
An alga that threatens freshwater ecosystems and is toxic to vertebrates has a sneaky way of ensuring its success: It suppresses the growth of algal competitors by releasing chemicals that deprive them of a vital vitamin.
-
NewsLiving near harmful algal blooms reduces life expectancy with ALS
Living close to cyanobacterial harmful algal blooms — which are present US-wide but are more common in coastal and Great Lake states — heightens the rate of dying from amyotrophic lateral sclerosis, or ALS, a study suggests.

NewsScientists discover the ‘ticking’ mechanism driving nature’s simplest circadian clock
Researchers have uncovered the molecular mechanism that drives the ’ticking’ of the circadian clock in cyanobacteria. A clock protein called KaiC controls chemical reactions with precision, acting like the hand of a clock that waits, then moves at just the right moment.
-
NewsResearch team traces evolutionary history of bacterial circadian clock on ancient Earth
To better understand the circadian clock in modern-day cyanobacteria, researchers studied ancient timekeeping systems. They examined the oscillation of the clock proteins in modern cyanobacteria, comparing it to the function of ancestral Kai proteins.

NewsLight-to-electricity nanodevice reveals how Earth’s oldest surviving cyanobacteria worked
An international team of scientists have unlocked a key piece of Earth’s evolutionary puzzle by decoding the structure of a light-harvesting “nanodevice” in one of the planet’s most ancient lineages of cyanobacteria.
