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.

NewsResearchers find CRISPR is capable of even more than we thought
Researchers studying key immune components of some CRISPR systems have announced the newest CARF effector they’ve discovered, which they coined Cat1 - it can deplete a metabolite essential for cellular function.

NewsNew treatment targets link between viral infection and Alzheimer’s disease
A unique mechanism triggering Alzheimer’s disease draws attention: viral infection—while ALT001 is confirmed to alleviate neuroinflammation and suppress viral replication.
-
NewsTwo HIV vaccine trials show proof of concept for pathway to broadly neutralizing antibodies
A new study combining data from two separate phase 1 clinical trials shows that a targeted vaccine strategy can successfully activate early immune responses relevant to HIV, and, in one trial, further advance them.
-
NewsScientists find two brain biomarkers in long COVID sufferers may be what’s causing brain fog
A new study that compares inflammation and brain stress responses in long COVID-19 patients with individuals who have fully recovered shows those with cognitive issues have a lower ability to adapt to stress and higher levels of inflammation in their brains.

NewsClimate change is turning coastal lagoons into ‘salty soup’
The impacts of human activity and climate change are coalescing to make coastal lagoons saltier, changing the microbial life they support and the function they play in their ecosystems, according to new research.

NewsYellow fever vaccination: how strong immune responses are triggered
Researchers have shown how specific immune cells are activated by the vaccine – an important starting point for the development of new vaccines.
