Study finds minimal SARS-CoV-2 viral load in vaginal secretions

The virus has also been observed to be present in blood, urine, feces, and tears, though not in semen. Vaginal secretions have not been consistently shown to be positive for the virus in most studies. The authors of a new study in the Journal of Clinical Medicine affirm that the presence of the virus in the vagina is rare, irrespective of pregnancy.

Bioactive packaging can keep strawberries fresh for up to 12 days

Québec produces more strawberries than any other Canadian province. Strawberries are delicate and difficult to keep fresh. In response to this challenge, Monique Lacroix, a professor at at the Institut national de la recherche scientifique, and her team have developed a packaging film that can keep strawberries fresh for up to 12 days.

Study reports self-disinfecting polymer surfaces that can inactivate SARS-CoV-2

Surfaces with anionic block copolymers can inactivate different viruses within minutes by making the polymer-microbe interface very acidic. Such surfaces can continuously disinfect surfaces without the need for reapplication of disinfectant.

Trained dogs can accurately identify COVID-19 by scent

An interesting new medRxiv* preprint reveals that with careful training, the exquisite scent sensitivity of dogs may be exploited to rule out the presence of coronavirus disease 2019 (COVID-19) in human beings in real-time.

Restoration can improve mining contamination, indicates study

Mining involves moving a lot of rock, so some mess is expected. However, mining operations can continue to affect ecosystems long after activity has ended. Heavy metals and corrosive substances leach into the environment, preventing wildlife and vegetation from returning to the area.

Novel method allows rapid, absolute quantification of viral nucleic acids

Researchers from Critical Analytics for Manufacturing Personalized-Medicine, an Interdisciplinary Research Group at the Singapore-MIT Alliance for Research and Technology, MIT's research enterprise in Singapore, have developed a new method for rapid and accurate detection of viral nucleic acids - a breakthrough that can be easily adapted to detect different DNA/RNA targets in viruses like the coronavirus.

CASdetec: new CRISPR-based SARS-CoV-2 detection platform detects nucleic acids with high sensitivity and specificity

To add to existing CRISPR-based nucleic acid detection protocols, a team of researchers recently established a new SARS-CoV-2 detection protocol based on their previously reported platform - CDetection (Cas12b-mediated DNA detection). They combined nucleic-acid amplification methods and sample treatment protocols with CDetection and established an integrated nucleic acid detection platform called CRISPR-assisted detection or CASdetec. CASdetec has a detection limit of 1×104 copies/mL for SARS-CoV-2 pseudovirus, without any observed cross-reactivity.

Non-droplet routes of SARS-CoV-2 transmission

In a recent review article published in the Science of The Total Environment journal, a group of Polish researchers discussed the different transmission routes of the severe acute respiratory coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus disease 2019 (COVID-19). In their work, the researchers focused on the extent of SARS-CoV-2 survival in the environment, particularly in sewages and contaminated surfaces.
