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.

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. Source: NIAID-RML This colorized transmission electron microscope image shows ...

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.

NewsDouble trouble: Tobacco use and Long COVID
Researchers investigating the relationship between Long Covid symptoms and smoking by tobacco type found that certain symptoms correlated with different forms of smoking.

NewsStudy identifies blood protein albumin as key defense against deadly fungal infection ‘mucormycosis’
A new study has identified albumin as a powerful and previously unrecognized defense against a rare but often fatal fungal infection. Patients with mucormycosis had markedly lower levels of albumin compared with patients suffering from other fungal infections.

NewsBiologists and engineers follow goopy clues to plant-wilting bacteria
Slippery, drippy goop makes Ralstonia bacteria devastating killers of plants, causing rapid wilting in tomato, potato and a wide range of other crops, according to new research.

NewsAncient DNA pushes back record of treponemal disease-causing bacteria by 3,000 years
Scientists have recovered a genome of Treponema pallidum from 5,500-year-old human remains in Sabana de Bogotá, Colombia. The research expands knowledge about the history of this infectious disease and its occurrence in human populations.

NewsLow vitamin D levels shown to raise risk of hospitalization with potentially fatal respiratory tract infections by 33%
Severe vitamin D deficiency is associated with a higher rate of hospitalisation for respiratory tract infections such as bronchitis and pneumonia. Scientists found that those with a severe deficiency (below 15 nnmol/L) were 33 per cent more likely to be admitted to hospital for treatment.

NewsMajor clinical trial provides definitive evidence of impacts of steroid treatment on severe brain infection
A major UK clinical trial has shown that adding the corticosteroid dexamethasone to standard antiviral treatment for encephalitis, caused by herpes simplex virus (HSV) does not improve long-term outcomes overall, although early use may lead to better recovery.

NewsOral bacterium may promote breast cancer development and spread
Researchers found that Fusobacterium nucleatum, an oral bacterium commonly associated with periodontal disease, can promote breast cancer initiation, tumor growth and spread by inducing DNA damage and altering cancer cell behavior.

NewsResearch team identifies species of brucellosis-causing bacteria in Cameroon
Researchers have identified the specific species of the Brucella bacterium that causes illness in animals in Cameroon. A study of more than 4,600 livestock animals found that the only Brucella species present was Brucella abortus, a species primarily associated with cattle that causes pregnancy loss and infertility.

NewsScientists discover novel immune ‘traffic controller’ hijacked by virus
Researchers have discovered a tissue protein that acts as a central ‘traffic controller’ for immune cells and can be hijacked by a virus to weaken immune responses. Cytomegalovirus (CMV) can hijack this system by producing a protein that blocks CD44 function on stromal cells.

NewsMost would recommend RSV immunizations for older and pregnant people
A US survey found an increase in awareness of immunizations that are available for RSV. The survey of 1,637 U.S. adults also found that about 6 in 10 respondents would recommend the vaccine or antibody injections to the groups recommended by the CDC, an increase from past years.
