NewsResearchers on the cusp of a vaccine for a global health threat
Researchers are on the cusp of a new vaccine to prevent chikungunya, a global health threat which attacks human joint tissue. The team tested whether they could engineer E. coli to assemble biopolymer particles which displayed chikungunya antigens and performed as a vaccine.

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.

NewsCARB-X to support development of typhoid fever diagnostic from Chembio
CARB-X is awarding US$1.8 million to Chembio Diagnostic Systems, Inc. to develop a rapid point-of-care test for the detection of Immunoglobulin A (IgA) antibodies to diagnose acute infection of Salmonella enterica serovar Typhi.

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.

NewsA mint idea becomes a game changer for medical devices
Researchers have developed a high‑performance coating made from peppermint essential oil that can be applied to the surfaces of many commonly used medical devices, offering a safer way to protect patients from infection and inflammation.

NewsYeast cells can be used for rapid testing of cancer immunotherapy
An international research team has developed a new yeast-based biotechnological platform that makes it possible to test and understand advanced cancer treatments much faster and cheaper than before. It can reduce development time for new types of cancer immunotherapy from months to days or weeks.

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.

NewsBlood test may give insights into a person’s infection history
Which infections have you already come into contact with? In the future, a simple blood test may be all you need to answer that question. Researchers intend to investigate the sensors the immune system uses to identify pathogens.
