NewsDiscovery of SARS-CoV-2 PLpro inhibitors and RIPK1 inhibitors with synergistic antiviral efficacy in a mouse COVID-19 model
A new article publication discusses the discovery of SARS-CoV-2 PLpro inhibitors and RIPK1 inhibitors with synergistic antiviral efficacy in a mouse COVID-19 model.

NewsNew study reveals cyanobacteria may help spread antibiotic resistance in estuarine ecosystems
Scientists have discovered that cyanobacteria may play a major role in spreading antibiotic resistance genes in coastal environments. The findings highlight a previously overlooked link between natural nutrient cycling and the global challenge of antibiotic resistance.

NewsTaxiing through the gut: Formic acid in the microbiome
Scientists have found that the gut bacterium Blautia luti produces formic acid (formate) instead of carbon dioxide (CO₂) and hydrogen, with hydrogen bound to CO₂. In this case, formic acid is the electron taxi, allowing the energetically costly production of hydrogen to be bypassed.

NewsLarge-scale study analyses the impact of climate on Legionnaires’ disease in Catalonia
A study has analysed the relationship between climatic conditions, the presence of Legionella in water systems and cases of Legionnaires’ disease in Catalonia. The link between these different factors highlights the need to adapt prevention and surveillance strategies in the context of climate change.

NewsNew study: Immune cells linked to Epstein-Barr virus may play a role in MS
Researchers have found that certain types of CD8+ “killer” T cells — immune cells that destroy damaged or infected cells — are more abundant in people with MS. Some of these killer T cells target EBV, which suggests that the virus may trigger the damaging immune response seen in MS.

NewsStudy reveals dual forces driving SARS-CoV-2 evolution: Immune pressure and viral fitness
New research clarifies the complex role of neutralizing antibodies in shaping disease outcomes and the evolution of SARS-CoV-2.

NewsOysters play unexpected role in protecting blue crabs from disease
Oysters famously filter their surrounding water, but it turns out they are removing more than algae and excess nutrients. New research shows they can also reduce the spread of disease in nearby marine species, including Chesapeake Bay’s prized blue crabs.

NewsBreakthrough in human norovirus research: Researchers overcome major obstacle to grow and study the virus
Researchers have overcome a major obstacle that limited their ability to continuously grow human norovirus. They identified factors that restrict viral replication and developed a way to overcome them to optimize long-term viral cultivation.

NewsResearchers probe how natto produces supersulfide molecules in fermentation
Natto, a Japanese food made from soybeans fermented with the Bacillus subtilis var. natto microorganism, is rich in supersulfide molecules, which are attracting attention in the medical and nutritional fields. Researchers extensively analyzed supersulfide content in natto fermentation using various methods.

NewsMalaria: Newly identified ‘crown’ stage controls parasite reproduction
Researchers studying Plasmodium falciparum have found that the parasite relies on a brief but essential stage, nicknamed the “Crown” stage, to make sure a crucial internal structure is passed on correctly when it divides.

NewsTesting menstrual blood for HPV could be “robust alternative” to cervical screening
Testing menstrual blood for human papillomavirus (HPV) could be a “robust alternative or replacement” for current cervical cancer screening by a clinician, finds a study. The researchers say using menstrual blood for HPV testing is convenient and non-invasive.

NewsA rapid evolutionary process provides Sudanese Copts with resistance to malaria
An international study investigating the genomic diversity of the Sudanese population reveals that the Copts originating in Egypt –who settled in the country between the seventh and eleventh centuries– have acquired a genetic variant that protects them from contracting malaria.
-
NewsNew study reveals a minimalist bacterial defense that disrupts viral assembly
Researchers describe how a single protein named Rip1 recognizes bacteriophages, the viruses that infect bacteria, and cause infected bacteria to die prematurely, thereby ending the chain of transmission.
-
NewsForest soils increasingly extract methane from atmosphere
Researchers evaluated the world’s most comprehensive data set on methane uptake by forest soils. They discovered that under certain climate conditions, which may become more common in the future, their capacity to absorb methane actually increases.
-
NewsGreen chemistry: Friendly bacteria can unlock hidden metabolic pathways in plant cell cultures
Co-culturing plant cells with harmless bacteria can expand the diversity of obtainable plant-derived compounds for pharmaceuticals, cosmetics, and agrochemicals, a new study shows.
-
NewsSugar molecules point to a new weapon against drug-resistant bacteria
Researchers have developed a powerful new way to target deadly, drug-resistant bacteria by designing antibodies that recognise a sugar found only on bacterial cells – an advance that could underpin a new generation of immunotherapies for multidrug resistant hospital-acquired infections.
-
NewsPreviously unknown viruses discovered in groundwater
Researchers have created a comprehensive picture of viral diversity and function in a groundwater system. They identified over 257,000 viral operational taxonomic units, i.e. viruses at species level, 99 % of which were previously unknown.

NewsGut microbe–derived butyrate activates immune cells to enhance vaccine efficacy
Researchers have uncovered a new mechanism showing how butyrate—a short-chain fatty acid produced by gut commensal bacteria—enhances T follicular helper (Tfh) cell activity to promote antibody production and strengthen mucosal vaccine efficacy.
-
NewsResearchers urge focus on child obesity and gut health to reduce risk of diabetes
Researchers are calling for more study of obesity, gut bacteria and metabolic conditions that arise in childhood and adolescence, with an eye to curbing the global rise of type 2 diabetes.

NewsSoil pH shapes nitrogen competition between wheat and microbes, new study finds
A new study reveals that soil acidity plays a critical role in determining how wheat competes with soil microorganisms for nitrogen, a nutrient essential for plant growth and global food production.
