News‘Picky eater’ parasitic archaea drive their hosts to change the menu
Scientists show that the parasitic archaeon Candidatus Nanohaloarchaeum antarcticus does not contain all the lipids that his host Halorubrum lacusprofundi contains, and the host responds to the presence of its parasites.

NewsHidden biosphere unveiled beneath world’s driest hot desert
In a finding with implications for the search for extraterrestrial life, researchers have discovered microbial life 13 feet below Earth’s most inhospitable desert.

NewsStudy uncovers molecular mechanism of chemical diversity of thermophilic fungus
The new findings might explain why Thermomyces species with a large reduced genome can survive in the biosphere where temperatures are often below their growth temperatures.

NewsMarine plankton behaviour could predict future marine extinctions, study finds
Marine communities migrated to Antarctica during the Earth’s warmest period in 66 million years long before a mass-extinction event.
-
NewsCoral reef microbes point to new way to assess ecosystem health
A new study shows that ocean acidification is changing the mix of microbes in coral reef systems, which can be used to assess ecosystem health.
-
NewsWild plants face viral surprise spreading from crops
A new study reveals a previously unknown threat: non-native crop viruses are infecting and jeopardizing the health of wild desert plants.

NewsAdditional nutrients intensify dead zones in oceans
As more and more nutrients from land and air enter the world’s oceans, the dead zones without oxygen in the water will increase in size and intensity, a new study warns.
-
NewsMissing puzzle piece discovered that influences sensitivity of gut bacterium to antibiotics
Scientists identify the small RNA that influences the sensitivity of the intestinal pathogen Bacteroides thetaiotaomicron to certain antibiotics.

NewsIn Lake Erie, climate change scrambles zooplankton’s seasonal presence
A new analysis of zooplankton in western Lake Erie shows that their biomass and seasonal behavioral patterns have been drastically altered by human-driven changes in water temperature and food webs.

NewsClimate change disrupts vital ecosystems in the Alps
Reduced snow cover and shifting vegetation patterns in the Alps, both driven by climate change, are having major combined impacts on biodiversity and functioning of ecosystems in the high mountains, according to new research published today.

NewsResearchers investigate how freshwater diatoms stay in the light
Scientists sampled the ice-covered (in 2019) and ice-free (in 2020) winter waters of Lake Erie to learn how diatoms are responding to changing environmental conditions.

NewsResearchers explore role of salps as predators of marine microbes
Salps play a major role in controlling the abundances and function of microbial communities in the vast nutrient-poor open ocean, with global implications, a new study reveals.

NewsPlankton model bridges the rules of life at individual scale and ecosystem level
Researchers have developed a model that connects microscopic biology to macroscopic ecology, which could deepen our understanding of nature’s laws and create new opportunities in ecosystem management.

NewsScientists home in on viruses that can help ‘dial up’ carbon capture in the sea
Scientists are now zeroing in on the viruses most likely to combat climate change by helping trap carbon dioxide in seawater or, using similar techniques, different viruses that may prevent methane’s escape from thawing Arctic soil.

NewsStudying defensive bacteria in squid and newts may help human gut health
Elizabeth Heath-Heckman has received a $1.9 million grant to support her research studying the bacteria animals like squid and newts use to protect themselves.

NewsExperiment shows how predator mass mortality events affect food webs
A team of biologists experimentally caused a predator die-off to understand how rapid predator deaths affect freshwater ecosystems.
-
NewsSoil fungi may help explain the global gradient in forest diversity
Mycorrhizal fungi appear to be counteracting the effects of harmful soil pathogens in ways that influence global patterns of forest diversity.
-
NewsMicrobial awakening shifts high-latitude food webs as permafrost thaws
A new study shows that fungi are replacing plants as the primary energy source for Arctic and boreal animals.
-
NewsProject investigates how biodiversity loss contributes to zoonosis risks
A newly launched project, titled ’Zoonosis Emergence across Degraded and Restored Forest Ecosystems’ (ZOE), is receiving about four million euros in funding from the European Commission for a period of four years.

NewsResearch addresses mystery of why diversity in plant species causes higher farming yield
A new study shows how a boost in agricultural yield comes from planting diverse crops rather than just one plant species - soil pathogens harmful to plants have a harder time thriving.
