NewsNatural sunscreen compounds show potential to support skin health and blood pressure
Researchers have discovered that natural ‘sunscreen’ compounds found in algae and cyanobacteria may also support skin and heart health.
-
NewsEarly intervention of cyanobacterial risks starting from the genome?
A new study proposes using “~3 Mbp” as a threshold to establish a genome size-oriented proxy indicator for cyanobacterial risk early warning.

NewsTeam shows how viral lysis of blue-green algae enhances ecosystem-scale productivity
Newly published interdisciplinary research shows viral infection of blue-green algae in the ocean stimulates productivity in the ecosystem and contributes to a rich band of oxygen in the water.

NewsA new natural sunscreen: novel compound discovered from thermophilic cyanobacteria
Natural sunscreens shield the skin from harmful radiation, without triggering allergic reactions. Researchers have discovered a novel compound, β-glucose-bound hydroxy mycosporine-sarcosine, which is produced in thermal cyanobacteria under UV-A/UV-B and salt stress.

NewsMicroalgal–Bacterial granules show resilience to estrogen pollution but face structural collapse at high contamination levels
A study reveals both the adaptive biodegradation potential and the vulnerability of MBGS under estrogenic stress, offering new insights for developing robust, biologically based wastewater treatment technologies.

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 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.
