NewsZika virus is effective when used to treat a type of childhood cancer in mice
Injecting neuroblastoma tumors with Zika virus shrank or eliminated those tumors in studies with mice, suggesting that the virus could someday serve as an effective cancer therapy, according to a new study.

NewsNaturally occurring pathogenic fungi recruited to control Eucalyptus snout beetle
Scientists have found naturally occurring pathogenic fungi infecting the Eucalyptus snout beetle in Eucalyptus forest plantations, and characterised them to develop a bio-pesticide for controlling the beetle.

NewsScientists reveal why chicken farms are a breeding ground for AMR bacteria
Scientists are one step closer to understanding how bacteria, such as E. coli and Salmonella enterica, share genetic material which makes them resistant to antibiotics.

NewsMore than 30 new species of bacteria discovered in patient samples
A team that has been collecting and analyzing patient samples containing unknown germs since 2014 have discovered more than 30 new species of bacteria, some of which are associated with clinically relevant infections.

NewsResearchers uncover how molecular freight elevators work in pathogenic bacteria
Researchers studying bacterial membrane transporters have studied the interaction between the transporter and its soluble substrate binding protein, showing that they adapt precisely to each other during the transportation process.
-
NewsGut bacteria combinations protect stem cell transplantation patients from dangerous immune reactions
Researchers have shown that graft versus host disease (GvHD) is less common when certain microbes are present in the gut. In the future, it may be possible to deliberately bring about this protective composition of the microbiome.

NewsResearchers decode the ‘cytokine storm’ in sepsis
The team found that three cytokine pairs were responsible for most of the body’s damaging response to sepsis.

NewsCOVID-19 vaccine strongly effective for children and adolescents during delta and omicron
Children and adolescents who received one of the main COVID-19 vaccines were significantly protected and showed no increased signs of cardiac complications compared to young people who were not vaccinated.
-
NewsResearchers discover molecular ‘barcode’ used by bacteria to secrete toxins
Researchers have discovered a molecular “barcode” system used by disease-causing bacteria to distinguish between beneficial and toxic molecules.

NewsSARS-CoV-2 BA.2.86 less resistant to vaccine, but may be a problem in the lung
New research shows that the recently emerged BA.2.86 omicron subvariant of the virus that causes COVID-19 can be neutralized by bivalent mRNA vaccine-induced antibodies in the blood.

NewsOldest thylakoids in fossil cyanobacteria uncover evolution of photosynthesis
Researchers have identified microstructures in fossil cells that are 1.75 billion years old. These structures, called thylakoid membranes, are the oldest ever discovered.
-
NewsResearchers unmask an old foe’s tricks to thwart new diseases
Researchers are studying Yersinia pestis, the bacterium that causes bubonic and pneumonic plague, to better understand its ability to evade the immune system and apply that understanding to control other pathogens.
-
NewsSoil fungi may help explain the global gradient in forest diversity
Mycorrhizal fungi appear to be counteracting the effects of harmful soil pathogens in ways that influence global patterns of forest diversity.
-
NewsResearchers identify why cancer immunotherapy can cause colitis
Studies in mice reveal the mechanism that induces this severe side effect and point to a solution that kills the cancer without causing gastrointestinal issues.

NewsNovel compound protects against infection by virus that causes COVID-19
Compounds that obstruct the “landing gear” of a range of harmful viruses can successfully protect against infection by the virus that causes COVID-19.
-
NewsSingle-point testing could miss cases of asymptomatic malaria
Dynamic, fluctuating levels of this parasite in people without symptoms argues against single-point testing to diagnose infections, a new study suggests.
-
NewsNew antibiotics make TB bacterium less pathogenic for humans
Researchers have identified new, antibiotic molecules that target Mycobacterium tuberculosis and make it less pathogenic for humans.

NewsMolecular link IDed between gut bacteria and excitatory brain signaling in C. elegans
A new study establishes a molecular link between specific B12-producing bacteria in the gut of the roundworm C. elegans and the production of acetylcholine, a neurotransmitter important to memory and cognitive function.
-
NewsScientists unlock the secrets of disease-causing fungus Aspergillus fumigatus
A new study demonstrates the pivotal role of the Mitogen-Activated Protein kinase MpkA in both gliotoxin production and self-protection.

NewsMicrobial awakening shifts high-latitude food webs as permafrost thaws
A new study shows that fungi are replacing plants as the primary energy source for Arctic and boreal animals.
