NewsBacteria and minerals work together to detoxify arsenic in contaminated soils
New research shows that the interaction between arsenic-oxidizing bacteria and goethite, a common Fe mineral, significantly accelerates the conversion of arsenic from its highly toxic form, arsenite [As(III)], into the less harmful arsenate [As(V)].

NewsPurified immunoglobulin F(ab′) 2 prevents lethal staphylococcal enterotoxin B intoxication in mice and rhesus monkeys
Purified F(ab′)2 fragments are an effective antidote to lethal SEB doses in mice and rhesus monkeys, and therefore might be a favorable candidate for treating patients with severe SEB intoxication, a new study suggests.

NewsScientists develop low-cost handheld sensor test for airborne bird flu
Researchers have developed a prototype sensor that detects a virus that causes bird flu (H5N1) in air samples. The low-cost handheld sensor detects the virus at levels below an infectious dose and could lead to rapid aerosol testing for airborne avian influenza.

NewsTranscription factor PoMbp1 promotes the growth of Pleurotus ostreatus by regulating polysaccharide utilisation
A study investigating the growth and development of Pleurotus ostreatus has found that PoMbp1 contains an APSES domain and localizes to the nucleus, indicating it belongs to the fungal-specific APSES transcription factors family.

NewsAntimicrobial resistance in soil bacteria without the use of antibiotics
Overuse of antibiotics is currently the primary reason for the rise of antimicrobial resistance (AMR), but researchers have shown that AMR can be found in soil bacterial communities due to microbial interactions too, driven by a species of predatory bacteria.

NewssiRNA-AGO2 complex inhibits bacterial gene translation: a novel therapeutic strategy for superbug infection
Scientists have demonstrated that exosomes can serve as delivery vehicles to introduce AGO2-loaded siRNA into the cytoplasm of bacteria, and in turn down-regulated gene expression of the mRNA that shares sequence complementarity to the siRNA.

NewsScientists probe Rhytismataceae on twigs of Rhododendron
Following a study of fungal specimens collected from the twigs of Rhododendron species in China, three new genera were proposed and 21 species residing in 11 genera of Rhytismataceae were delimited, which include 18 new species and three new combinations.

NewsFewer than half of parents think they have accurate information about bird flu
Most parents say they don’t know if there have been cases of bird flu in their state, and less than half feel that they are able to find accurate and current information about it, according to a new national US poll.

NewsNew study links sleep debt and night shifts to increased infection risk among nurses
A new study examining the effects of sleep patterns and shift work on the immune system has found that sleep debt and night shifts increase the risk of several common infections in nurses.

NewsBacterial ‘jumping genes’ can target and control chromosome ends
Researchers have discovered a new mechanism that transposons, or “jumping genes” use to survive and propagate in bacteria with linear DNA, with applications in biotechnology and drug development.

NewsPackets of freeze-dried bacteria grow biocement on demand
Researchers report a freeze-drying approach that preserves biocement-producing bacteria, potentially allowing construction workers to use powder out of a packet to quickly make tiles, repair oil wells or strengthen the ground for makeshift roads.
