NewsTB and HIV treatments are not enough for a full recovery
Existing treatments control TB and HIV, but the immune system does not revert to normal, helping explain why people living with HIV remain susceptible to infections and underscoring the need for immunotherapies.

NewsAboard the International Space Station, viruses and bacteria show atypical interplay
In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless “microgravity” conditions aboard the International Space Station, but the dynamics of virus-bacteria interactions differed from those observed on Earth.

NewsWhy don’t antibiotic-making bacteria self-destruct?
Scientists discovered a promising new antibiotic in a soil sample. The molecule, lariocidin, is produced by the microbe Paenibacillus and shows broad activity against pathogenic bacteria. Now, the researchers report how Paenibacillus avoids harm by its own antibiotic.

NewsScientists observe infections by cancer-causing retroviruses in koalas as they occur
Scientists analysed the ongoing colonization by two retroviruses of the germline of koalas and resulting deaths from cancer in multi-generational pedigrees of over 100 koalas in US and European zoos. They calculated genetic risk scores (GRS) that can help guide koala breeding programs.

NewsWhen a virus releases the immune brake: New evidence on the onset of multiple sclerosis
A study investigating the links between Epstein-Barr virus and multiple sclerosis shows that EBV can interfere with the control of B cells. One viral protein mimics a crucial “approval” signal that B cells usually require from other immune cells. Self-reactive B cells can then survive even when they should be shut down.

NewsResearch reveals hidden diversity of E. coli driving diabetic foot infections
New research has shed light on the diversity and characteristics of E. coli strains that drive diabetic foot infections, providing the first comprehensive genomic characterisation of E. coli strains isolated directly from diabetic foot ulcers across multiple continents.

NewsNew mechanism links Epstein-Barr virus to MS
Scientists investigating the links between the Epstein-Barr virus and multiple sclerosis show that when the immune system fights EBV, certain T cells – which normally attack the virus – can also react to a protein in the brain called Anoctamin-2 (ANO2), a phenomenon called molecular mimicry.

NewsBirding enthusiasts can help songbirds avoid salmonella epidemics
Biologists are developing a tool to predict when deadly salmonella outbreaks are likely to happen in wild songbird populations so that people can protect their feathered friends by taking down bird feeders at the right time.

NewsNot only toxic but also a nutrient: guanidine as a nitrogen source
Cyanobacteria are key ecological players of global carbon and nitrogen cycles. They are also becoming increasingly important for carbon-neutral biotechnology. They could serve as green cell factories for a light-driven and sustainable production of chemicals and fuels – a central pillar of the sustainable bioeconomy. Source: André Künzelmann/UFZ ...

NewsGenetic risk factor and viral infection jointly contribute to MS
One of the leading triggers for multiple sclerosis (MS) is an infection with the Epstein-Barr virus. However, certain gene variants also play an important role. Researchers have shown that it is the molecular interaction between environmental and genetic risk factors that ultimately triggers the disease.

NewsProbiotic living microneedles designed by interbacterial competition for accelerated infected wound healing
Probiotic therapy offers a promising strategy for chronic infected wound management. Inspired by bacterial competitive interactions, researchers developed a multifunctional microneedle (MN) platform to overcome the limitations of weak competitiveness and poor penetration across biofilm barriers.

NewsNew test could help pinpoint IBD diagnosis, study finds
A test that rapidly detects signs of inflammatory bowel disease (IBD) in stool samples could improve future diagnosis and monitoring of the condition, a study suggests. The luminescent reporter lights up when it detects a molecule linked to gut inflammation.

NewsRare microbial wrinkle structures - signs of ancient life - turn up in an unexpected place
Deep water sediment layers in the Dadès Valley in the Central High Atlas Mountains of Morocco have revealed rare microbial wrinkle structures formed far from sunlight.

NewsFirst extensive study into marsupial gut microbiomes reveals new microbial species and antimicrobial resistance
New research provides the first metagenomic data for 13 marsupial species , including the red kangaroo and the common brushtail possum. They revealed that host family, animal location, and diet all contributed towards variance between different microbiomes.

NewsA protein found in the GI tract can neutralize many bacteria
The mucosal surfaces that line the body are embedded with defensive molecules that help keep microbes from causing inflammation and infections. One of these molecules, intelectin-2, has broad-spectrum antimicrobial activity against bacteria found in the GI tract.

NewsNew hypothesis links HPV E6 and SARS‑CoV‑2 spike proteins to reduced p53 activity
Scientists have proposed a hypothesis suggesting that virally encoded proteins such as HPV-E6 or SARS-COV-2 Spike may cooperate in suppressing host defenses including tumor suppressor mechanisms involving p53.

NewsA gentler way to model deadly lung infections in old age
Researchers report a refined mouse model that successfully mimics chronic Pseudomonas aeruginosa lung infection in old age. The study introduces an agar bead-based delivery strategy that allows bacteria to persist in the lungs of aged mice without causing rapid death.

NewsInjectable hydrogel-mediated co-delivery of oncolytic adenovirus and melphalan for retinoblastoma control and vision preservation
The collagen-based hydrogel enabled controlled oncolytic adenovirus and melphalan release and sustained retention. This approach eradicated retinoblastoma tumors and restored normal ocular structure and visual function following intravitreal administration.
