Rosin soap as a potential SARS-CoV-2 disinfectant

In a research paper recently uploaded to the preprint server bioRxiv* by Bell et al. (July 19th, 2021), the potential of rosin soap as a virucide is investigated, finding a ten-thousand-fold drop in infectivity against enveloped viruses such as influenza and SARS-CoV-2 in particular.

Novel microfluidic device used to manipulate major whey protein

After gaining world attention by 'unboiling' egg protein, Flinders University scientists have now used an Australian-made novel thin film microfluidic device to manipulate Beta-lactoglobulin (β-lactoglobulin), the major whey protein in cow's, sheep's and other mammals.

Bacteria use a 'sense of touch' mechanism to navigate on surfaces

Many disease-causing bacteria such as Pseudomonas aeruginosa crawl on surfaces through a walk-like motility known as "twitching". Nanometers-wide filaments called type IV pili are known to power twitching, but scientists ignore which sensory signals coordinate the microbes' movements.

Cell-analysis method could pave the way for new vaccine strategies against tuberculosis

A new method that analyzes how individual immune cells react to the bacteria that cause tuberculosis could pave the way for new vaccine strategies against this deadly disease, and provide insights into fighting other infectious diseases around the world.

'Good cholesterol' protects the liver from inflammation and injury, study shows

The body's so-called good cholesterol may be even better than we realize. New research from Washington University School of Medicine in St. Louis suggests that one type of high-density lipoprotein (HDL) has a previously unknown role in protecting the liver from injury.

Antibiotics may be the new weapon to fight against melanoma

Some antibiotics appear to be effective against a form of skin cancer known as melanoma. Researchers at KU Leuven, Belgium, examined the effect of these antibiotics on patient-derived tumours in mice. Their findings were published in the Journal of Experimental Medicine.

Traditional Japanese dish may hold an answer to COVID-19

Natto, a fermented soybean dish often served for breakfast in Japan, originated at the turn of the last millennium but may hold an answer to a modern problem: COVID-19, according to a new study based on cell cultures.

New study disproves suspicion that dengue raises risk of zika-related microcephaly

A pregnant woman infected by zika virus does not face a greater risk of giving birth to a baby with microcephaly if she has previously been exposed to dengue virus, according to a Brazilian study that compared data for pregnant women in Rio de Janeiro and Manaus.

Study finds dramatic decreases in antibiotic dispensing for children during the pandemic

As children made fewer visits to health facilities and engaged in social distancing and other COVID-19 mitigation measures, a smaller number of them also received prescription drugs, a new study suggests.

A low-cost biopolymer dressing to help heal chronic wounds

Tens of millions of patients around the world suffer from persistent and potentially life-threatening wounds. These chronic wounds, which are also a leading cause of amputation, have treatments, but the cost of existing wound dressings can prevent them from reaching people in need.

Dysbiosis in gut microbiota may cause severe secondary infection in COVID-19 patients

An interesting study led by scientists in the U.S. has recently revealed that the microbial community in the gut is directly affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and that virus-mediated gut microbiome dysbiosis may cause severe secondary infections in coronavirus disease 2019 (COVID-19) patients. The study is currently available on the bioRxiv* preprint server.

Grab your mask and notepad, we’re headed back to California’s state Capitol

The best part about returning to the pandemic-besieged state Capitol is that the elected officials are so unused to seeing us reporters after more than a year that some are occasionally extra chatty. The bad part is that the masks make it harder to eavesdrop on the rest of them.
