Fighting respiratory virus outbreaks through 'nano-popcorn' sensor-based rapid detection
Respiratory diseases like influenza can spread rapidly and escalate to global health crises. Thus, to control them, simple yet sensitive detection techniques are needed. Surface-enhanced Raman scattering (SERS) is a potential candidate but currently lacks reproducibility. To overcome this, researchers in Korea have now developed a novel SERS-based sensor that can effectively detect influenza A viral pathogens with high reproducibility. Through this improved method of detection, preventing future outbreaks of respiratory diseases can become easier. (2021-01-21)

They identified novel viruses and viral genome structures and show that FLDS is a powerful tool for understanding RNA viral genome diversity. (2020-12-21)

Scientists get the most realistic view yet of a coronavirus spike's protein structure
Coronaviruses like the one that causes COVID-19 are studded with protein ''spikes'' that bind with receptors on the cells of their victims ¬- the first step in infection. Now scientists have made the first detailed images of those spikes in their natural state, while still attached to the virus and without using chemical fixatives that might distort their shape. Their method should produce quicker and more realistic snapshots of the infection apparatus, a critical step in designing therapeutic drugs and vaccines. (2020-12-18)

Research strongly suggests COVID-19 virus enters the brain
The SARS-CoV-2 virus, like many viruses before it, is bad news for the brain. In a study published Dec. 16, 2020 in Nature Neuroscience, researchers found that the spike protein, often depicted as the red arms of the virus, can cross the blood-brain barrier in mice. The spike proteins alone can cause brain fog. Since the spike protein enters the brain, the virus also is likely to cross into the brain. (2020-12-17)

(2020-12-10)

Tasmanian devils may survive their own pandemic
Researchers have found strong evidence that a transmissible cancer that has decimated Tasmanian devil populations likely won't spell their doom. For the first time, a research team employed genomic tools of phylodynamics, typically used to track viruses, such as influenza and SARS-CoV-2 , to trace the Tasmanian devil facial tumor disease. The approach they pioneered has opened the door for application to other genetically complex pathogens. (2020-12-10)

(2020-12-07)

Drug for rare disorder shows promise for treating herpes viruses
New research shows that the antiviral activity of the drug -- called phenylbutyrate, or PBA -- was even better when used along with acyclovir, a common HSV-1 treatment. When used in combination, less acyclovir is needed to effectively suppress the virus compared to acyclovir alone -- this is important because acyclovir is also known to have toxic side effects in the kidneys.

How 'smell training' could help overcome post-viral smell distortions
Smell loss is a prominent symptom of Covid-19 and the pandemic is leaving many people with long-term smell loss or smell distortions such as parosmia. Parosmia happens when people experience strange and often unpleasant smell distortions. Instead of smelling lemon you may smell petrol. New research shows that parosmia is associated with a recovery of smell performance among patients who undergo 'smell training' (sniffing at least four different odours twice a day every day for several months). (2020-11-30)
