NewsNovel insecticides thought safe for honey bees are devastating their gut flora
Insecticides containing flupyradifurone and sulfoxaflor damage honey bees’ intestinal flora, especially when used in conjunction with a common fungicide, making them more susceptible to disease and shortening their life span.

NewsConan’s survival in extreme conditions suggests ancient bacteria might lurk beneath Mars’ surface
Researchers have found that ancient bacteria could survive close to the surface on Mars much longer than previously assumed.
-
NewsMarine bacteria take in carbon dioxide through photosynthesis
Researchers in China have identified carbon-dioxide-fixing cells from seawater and determined that their sample contains functioning genes for light harvesting, suggesting that the bacteria engage in photosynthesis.

NewsNicotine-degrading bacteria protects against smoking-related liver disease in mice
A gut bacterium capable of breaking down nicotine and protecting against smoking-related fatty liver disease progression in a mouse model has been identified in a Nature paper.

NewsmRNA vaccines significantly reduce severity of Delta, Omicron COVID-19 infections
People who have received several doses of an mRNA COVID-19 vaccine are more likely to have milder illnesses if infected with Delta or Omicron variants than those who are unvaccinated.

NewsBreakthrough in protecting bananas from Panama disease
A study by scientists in Exeter has provided hope that Panama disease in bananas may be controlled by a specialised class of anti-fungal chemistries.
-
NewsMushroom that grows on insects could help develop new anti-viral medications and cancer drugs
Scientists have discovered a way to grow Cordyceps fungus in the lab without losing the potency of its bioactive compound, cordycepin, which could potentially be developed into powerful new antiviral medications and cancer drugs.

NewsScripps Research scientists map key protein structure of Hepatitis C virus
Scientists have mapped critical proteins that stud the surface of the Hepatitis C virus (HCV) and enable it to enter host cells.
-
NewsCytoskeleton septins act as cell defence to block bacteria incursion
Researchers have identified a previously unknown, natural, defense mechanism that protects cells from Pseudomonas aeruginosa infection, as revealed in a study published in Cell Reports.

NewsMellow yellow pigment keeps social amoebae clustering
The multicellular stage of the amoeba Dicyostelium discoideum is partially regulated by an intensely yellow natural substance, scientists have discovered.
-
NewsSugar teams up with protein to help tardigrades survive drying out
University of Wyoming researchers have discovered how a sugar called trehalose works with proteins to allow tardigrades to survive a severe lack of water.
-
NewsMethod for singling out HIV virus’s most dangerous parts could lead to new drugs
A new technique could make it possible to identify the most dangerous parts of the HIV virus, so they can be singled out for attack.
-
News119-million-year-old selfish genes discovered in yeast
Scientists who discovered 119-million-year-old selfish genes in yeast say the find potentially alters our understanding of how parasitic DNA impacts genome evolution.
-
NewsClimate change could make High Arctic fertile ground for emerging pandemics
Melting glaciers increase the risk of viral spillover, suggesting the impact of climate change could lead viruses to infect new hosts in the Arctic, according to researchers at the University of Ottawa who performed a novel genetic analysis.
-
NewsMethane-eating ‘borgs’ have been assimilating earth’s microbes
Scientists have described the curious collection of genes in so-called borgs, DNA packages that could help humans fight climate change.
-
NewsAttack on two fronts leads ocean bacteria to require carbon boost
The types of ocean bacteria known to absorb carbon dioxide from the air require more energy – in the form of carbon – and other resources when they’re simultaneously infected by viruses and face attack from nearby predators, new research has found.
-
NewsResearchers discover how bacteria make pancreatic cancer cells grow and move
Virginia Tech researchers from the Department of Biomedical Engineering and Mechanics and the Department of Biochemistry have discovered a characteristic of a common oral bacterium that relocates to pancreatic cancer tumours that may help guide future therapeutic interventions for treatment.
-
NewsAlterations to gut mucus may trigger ulcerative colitis
Research published in the Proceedings of the National Academy of Sciences proposes a set of conditions that could act as a starting point for the development of ulcerative colitis.

NewsNew Omicron subvariant largely evades neutralizing antibodies, raising spectre of increased Covid infections this winter
A study at Karolinska Institutet in Sweden shows that the coronavirus variant BA.2.75.2, an Omicron sublineage, largely evades neutralizing antibodies in the blood and is resistant to several monoclonal antibody antiviral treatments.
