NewsAddressing rapid viral evolution: research team unveils emerging techniques for RNA viruses diagnostics
The rapid evolutionary dynamics of RNA viruses, driven by high mutation rates and the consequent formation of complex quasispecies populations, present a formidable obstacle to conventional molecular diagnostic approaches, warn researchers.

NewsNasal vaccine combats bird flu infection in rodents
Researchers have developed an intranasal H5N1 vaccine that elicited strong immune responses when tested in hamsters and mice and prevented infections in exposed animals. The team also confirmed their vaccine remained effective regardless of prior flu exposure.

NewsA rapid test using a mobile phone will be able to identify the most severe cases of imported malaria within minutes
A new malaria tool uses a mobile phone to combine rapid diagnostic tests with video analysis and is capable not only of detecting the infection in under six minutes but also of predicting which patients may develop severe forms of malaria.

NewsInstitut Pasteur issues statement on U.S. administration’s attacks against biomedical research, global public health action and vaccination
For several months now, the current U.S. administration has consistently attacked and endeavored to weaken biomedical research and public health action in the United States and worldwide with unparalleled vigor, the Institut Pasteur has said in a new statement.

NewsNew tool shows how to enter and change pneumocystis fungi
Researchers have reported success in genetically modifying the fungal pathogen Pneumocystis murina. Their approach uses extracellular vesicles from mouse lungs to deliver gene-modifying molecules inside the fungal cells. The modified fungus expressed the introduced genomic modifications.

NewsScientists say these two viruses may become the next public health threats
Two emerging pathogens with animal origins — influenza D virus and canine coronavirus — have so far been quietly flying under the radar, but researchers warn conditions are ripe for the viruses to spread more widely among humans.

NewsIn rare cases, autoantibodies can cause severe reactions to a live-attenuated virus Chikungunya vaccine that has been discontinued in the U.S.
A new study shows that preexisting autoantibodies in a small subset of the population can allow weakened vaccine viruses to escape control, explaining some adverse events tied to one kind of Chikungunya vaccine, which is no longer available in the U.S.

NewsNew platform could develop vaccines faster than ever before
Scientists are optimizing a vaccine-development platform created to accelerate how quickly life-saving vaccines can be designed and deployed during infectious-disease outbreaks such as the COVID-19 pandemic.

NewsPreparedness for future pandemics: MERS vaccine candidate shows long-lasting immune response
A new study has shown for the first time that an experimental vaccine against Middle East Respiratory Syndrome (MERS) induces a stable and functional immune response in humans that persists for at least two years after a booster vaccination.

NewsSerum interleukin-8 can tell pulmonary aspergillosis from bacterial pneumonia in patients with liver failure
Scientists found serum interleukin-8 can be used to differentiate invasive pulmonary aspergillosis from bacterial pneumonia in patients with HBV-associated acute-on-chronic liver failure.

NewsScientists find hidden diversity inside common brain parasite
Scientists have found that Toxoplasma gondii is far more complex than previously believed. Until now, cysts were believed to contain a single, uniform type of parasite lying dormant until reactivated, but have now been found to contain multiple distinct subtypes of parasites, each with different biological roles.

NewsResearchers demonstrate SARS-CoV-2 virus inactivation/destruction using focused sound waves
A team of researchers has successfully demonstrated the destruction of SARS-CoV-2 virus particles through exposure to high-frequency sound waves, marking a promising advance in non-pharmacological antiviral strategies.

NewsCOVID-19 viral fragments shown to target and kill specific immune cells
New research shows that after the body’s defenses kill the virus behind COVID-19, leftover digested chunks of SARS-CoV-2 spike protein can target specific immune cells based on their shape. It could explain why certain populations of cells that detect and fight infection are depleted in patients with severe COVID-19.

NewsNative fungi from almond orchards show promise as sustainable defenders against a devastating crop disease
Researchers report that naturally occurring fungi found on and within almond trees can strongly suppress Colletotrichum godetiae, the primary cause of almond anthracnose in the Mediterranean Basin.

NewsStudy cites link between mental health and long COVID in older women
Older women who have a history of both depression and anxiety had a 78% higher risk of developing long COVID after a SARS-CoV-2 infection, report researchers. Infection rates were not higher; only their risk of complications increased.

News‘Nudging’ both patients and providers boosts flu vaccine numbers
Patients were 28 per cent more likely to get a flu shot when they got a text message reminder and their primary care provider already had an order for the shot waiting, new research showed.

NewsLong COVID brain fog far more common in US than India, other nations
Patients with long COVID-19 in the U.S. report far higher rates of brain fog, depression and cognitive symptoms than patients in countries such as India and Nigeria, according to a large international study.

NewsPlants can be designed to alert us to harmful chemicals and diseases
A collaborative team of researchers have developed groundbreaking tools that allow grasses—including major grain crops like corn—to act as living biosensors capable of detecting minute amounts of chemicals in the field.

NewsScientists develop novel live-attenuated vaccine that blocks coronavirus transmission with a single intranasal dose
A research team at the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), has developed a novel live-attenuated vaccine candidate, cb1, capable of generating broad immunity against a wide range of beta-coronaviruses with a single intranasal dose.

News3′UTR-derived small RNA couples acid resistance to metabolic reprogramming in Salmonella within macrophages
Salmonella expresses the arginine decarboxylase AdiA, which confers acid resistance by catalyzing an H+-consuming reaction. Researchers have discovered that the 3′-untranslated region (UTR) of adiA mRNA is processed by RNase E into a regulatory small RNA, AdiZ.
