Studying viral outbreaks in single cells could reveal new ways to defeat them
- ScienceDaily
- 20/8/20 16:24
Many viruses mutate so quickly that identifying effective vaccines or treatments is like trying to hit a moving target. A better understanding of viral propagation and evolution in single cells could help. Now, scientists report a new technique that can detect minor changes in RNA sequences in living cells that might give viruses an edge.

Australia's wish list of exotic pets
- ScienceDaily
- 20/8/20 16:24
Unsustainable trade of species is the major pathway for the introduction of invasive alien species at distant localities at higher frequencies. It is also a major driver of over-exploitation of wild populations. In a new study scientists estimate the desire of Australians to own non-native and/or illegal pets and the major trends in this practice. In addition, the team suggests ways to improve...
COVID-19: How South Korea prevailed while the United States failed
- ScienceDaily
- 20/8/20 16:24
In a commentary, researchers demonstrate the stark differences in public health strategies from two democratic republics: South Korea and the United States, which have led to alarming differences in cases and deaths from COVID-19. After adjusting for the 6.5 fold differences in populations, the U.S. has suffered 47 times more cases and 79 times more deaths than South Korea.
Study adds to evidence that cells in the nose are key entry point for SARS CoV-2
- ScienceDaily
- 20/8/20 16:24
Scientists experimenting with a small number of human cell samples report that the 'hook' of cells used by SARS-CoV-2 to latch onto and infect cells is up to 700 times more prevalent in the olfactory supporting cells lining the inside of the upper part of the nose than in the lining cells of the rest of the nose and windpipe that leads to the lungs.
Unique protein structures could hold the key to treatment for Parkinson's disease
- ScienceDaily
- 20/8/20 16:24
Scientists have discovered a series of protein structures that are thought to be highly relevant to the onset of Parkinson's disease. It is hoped that further analysis of these structures will open up a new avenue for potential treatment for a disease that is the fastest growing neurological condition in the world, with no cure currently available.

- 20/8/20 16:24
The more dogs are engaged in activities and the more diverse experiences and canine friends they have, the less fearful they are in new situations and environments. Genes also play an important part.
Defiance and low trust in medical doctors related to vaccine scepticism
- ScienceDaily

A new study shows that individuals who react negatively to rules and recommendations and have lower trust in doctors more often use complementary and alternative medicine, that is, treatments or substances that are not included in the care offered or recommended by doctors.
Yes, climate change is almost certainly fueling California’s massive fires
Thousands of lightning strikes have sparked hundreds of fires across California in recent days, producing several major clusters burning around the San Francisco Bay Area.
The blazes quickly ripped through hundreds of thousands of acres, forcing thousands to evacuate, filling the skies with smoke, and raining down ash across much of the region.
The fires follow a bone-dry winter in Northern...
Singing is no more of a COVID-19 risk than talking but volume matters, UK study finds
Singing is no more risky than speaking when it comes to the possibility of spreading the new coronavirus, British scientists said on Thursday, adding that volume is the most important risk factor. The researchers found that the aerosol mass produced rose steeply with an increase in volume of singing or speaking, by as much as 20 to 30...
Report urges action on flooding, erosion from climate change
Increased tidal flooding, beach erosion and aging sea barriers are among the climate change concerns threatening a famous coastal destination in Massachusetts, according to a report released Thursday by a leading conservation group in the state. The “State of the Coast” report by The Trustees focuses on the threat of rising sea levels and powerful storm surges on the state’s North Shore,...

The coronavirus responders
Countries that responded wisely to the pandemic run the gamut in terms of wealth, size, population, and style of government. What they shared was a swift, coordinated government response. Where that has been lacking, no amount of scientific expertise, technical knowhow, or wealth can prevent disaster, as the United States all too grimly shows.
