NewsResearchers reveal how microbes can swim without a brain
Many microorganisms can move in a goal oriented way in liquids, despite the lack of a complex nervous system. New research explains the behaviour of microorganisms, and could also enable nanobots to move in a targeted manner.

NewsCommon drugs can help viruses spread
JAK inhibitors are often prescribed for autoimmune diseases and inflammatory conditions such as rheumatoid arthritis, but scientists have found they also weaken the body’s natural defences against viruses.

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.

NewsCould nanoplastics in the environment turn E. coli into a bigger villain?
New research suggests certain nanoplastics may make foodborne pathogens more virulent. Nanoplastics with positively charged surfaces were more likely to cause physiological stress in E. coli O157:H7, making them pump out more Shiga-like toxin.

NewsHow the Epstein-Barr virus promotes its spread within the body
Researchers have discovered that the Epstein-Barr virus (EBV) increases the ability of infected immune cells to migrate. In this way, the pathogen promotes its spread in the body – a discovery that may have therapeutic implications.

NewsGenomic data shows widespread mpox transmission in West Africa prior to 2022 global outbreak
Mpox was transmitted among humans in Nigeria for eight years before sparking the international outbreak in 2022. Using genomic tracing, the researchers estimate that the virus’s ancestor first emerged in southern Nigeria in August 2014.

NewsStudy probes why patients with mitochondrial disease are more susceptible to infections
A new study shows that damaged mitochondria put the immune system in a constant state of alert, leading to dangerous overreactions when patients with rare mitochondrial diseases encounter bacteria.

NewsOcean microbes offer clues to environmental resilience
Researchers have developed a new way to identify genetic changes that help tiny oxygen-producing microbes survive in extreme environments.

NewsRising temperatures lead to unexpectedly rapid carbon release from soils
Scientists investigate the sensitivity of soil carbon, which is directly related to the release of CO2 from soils, under a changing climate, such as rising temperatures and/or variations in the hydrological cycle.

NewsHeat-tolerant symbionts a critical key to protecting elkhorn coral from bleaching during marine heatwaves
Heat-tolerant symbiotic algae may be essential to saving elkhorn coral (Acropora palmata)—a foundational species in Caribbean reef ecosystems—from the devastating impacts of marine heatwaves and coral bleaching.

NewsMicroalgae remove antibiotic residues from wastewater, reducing environmental contamination
In the laboratory, the species Monoraphidium contortum removed some of the drugs added to the liquid and produced biomass with potential commercial value.

NewsNovel molecular maneuver helps malaria parasite dodge the immune system
Researchers have discovered how a parasite that causes malaria when transmitted through a mosquito bite can hide from the body’s immune system. Plasmodium falciparum can shut down a key set of genes, rendering itself “immunologically invisible.”
-
NewsSeawater microbes are powerful tool for diagnosing coral reef health and strengthening conservation efforts
Microorganisms in the water surrounding coral reefs provide valuable insights on the health state of reefs and surrounding ocean. Sampling and analyzing reef water microbes can be done in a variety of ways ranging in cost and complexity, adding to their usability.

NewsSulfate-reducing bacteria drive elevated levels of mercury in Colorado mountain wetlands
Climate change is melting glaciers and permafrost in mountains, freeing up minerals containing sulfate to flow downstream into local watersheds. Elevated sulfate levels can increase methylmercury, a potent neurotoxin that accumulates up the food chain.

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.
-
NewsDual associations with two fungi improve tree fitness
Many tree species have formed a concurrent symbiosis with two different groups of mycorrhizal fungi. Those trees cope better with water and nutrient scarcity, which is an important trait for forestry in the face of climate warming.
-
NewsFamily of parasite proteins presents new potential malaria treatment target
Researchers from the Francis Crick Institute and the Gulbenkian Institute for Molecular Medicine (GIMM) have shown that the evolution of a family of exported proteins in the malaria-causing parasite Plasmodium falciparum enabled it to infect humans. Source: Ernst Hempelmann Ring stage of Plasmodium falciparum in human red blood ...

NewsVicious cycle: How methane emissions from warming wetlands could exacerbate climate change
Warming in the Arctic is intensifying methane emissions, contributing to a vicious feedback loop that could accelerate climate change even more, according to a new study.

NewsAmericans say benefits of MMR vaccine for children outweigh risks by nearly 5-1
While many Americans know how measles can spread, most cannot accurately estimate the prevalence of complications associated with measles such as hospitalization or the risks it presents during pregnancy, according to a new survey.

NewsAI predicts bacterial resistance to cleaning agents
With the help of artificial intelligence and DNA decoding, a new method can predict how well disease-causing bacteria such as Listeria tolerate disinfectants. This research may become a valuable weapon in the fight against harmful bacteria.
