Antibodies and SARS-CoV-2 infections: Tthe more the better
Oxford University Hospital tracked infections in 12,500 of its healthcare workers. Enlarge / Oxford University is associated with the hospital that ran this study, as well as a vaccine that is currently undergoing clinical trials. (credit: Gallo.....»»
Antibiotic-resistant bacteria found in cattle, but new technology can help with detection
Growing resistance to our go-to antibiotics is one of the biggest threats the world faces. As common bacteria like strep and salmonella become resistant to medications, what used to be easily treatable infections can now pose difficult medical challe.....»»
A detailed simulation of air flow after sneezing
By the beginning of April 2021, the number of people infected during the COVID-19 pandemic had risen to more than 130 million people of whom more than 2.8 million died. The SARS-CoV-2 virus responsible for COVID-19 is transmitted particularly by drop.....»»
How Dangerous Is the Delta Variant, and Will It Cause a COVID Surge in the U.S.?

Key mutations in Alpha variant enable SARS-CoV-2 to overcome evolutionary weak points
One of the key mutations seen in the 'Alpha variant' of SARS-CoV-2—the deletion of two amino acids, H69/V70—enables the virus to overcome chinks in its armour as it evolves, say an international team of scientists......»»
Fungal infections worldwide are becoming resistant to drugs and more deadly
Say "fungus" and most people in the world would probably visualize a mushroom......»»
More bacteria are becoming resistant to antibiotics: How viruses and vaccines could help
Antibiotic resistant bacteria are killing more people each year, but scientists are turning to their natural virus predators to treat infections, as well as new vaccines to prevent disease......»»
Abu Dhabi Starts Using Facial Covid Scanners at Malls and Airports
Abu Dhabi will use facial scanners to detect coronavirus infections at malls and airports starting Monday, after a trial of 20,000 people showed "a high degree of effectiveness." From a report: The technology can detect infections by measuring electr.....»»
Structural changes in the SARS-CoV-2 Alpha and Beta variants identified
New SARS-CoV-2 variants are spreading rapidly, and there are fears that current COVID-19 vaccines won't protect against them. The latest in a series of structural studies of the SARS-CoV-2 variants' "spike" protein, led by Bing Chen, Ph.D., at Boston.....»»
SARS-CoV-2 virus can find alternate route to infect cells
Early in the COVID-19 pandemic, scientists identified how SARS-CoV-2, the virus that causes COVID-19, gets inside cells to cause infection. All current COVID-19 vaccines and antibody-based therapeutics were designed to disrupt this route into cells,.....»»

Children"s Birthdays May Have Spread COVID Infections
The risk of infection increased by up to 30 percent or so among people with observances in the first 10 months of 2020 -- Read more on ScientificAmerican.com.....»»
The Challenge of Covid-19 Vaccines for the Immunosuppressed
Recent studies find transplant patients and immune-suppressed people who get the shot don’t make many antibodies. But that research is just beginning......»»
Versatile, fast and reliable SARS-CoV-2 antibody assay
During the continued progression of the Corona pandemic, rapid, inexpensive, and reliable tests will become increasingly important to determine whether people have the associated antibodies—either through infection or vaccination. Researchers at th.....»»
No lab required: New technology can diagnose infections in minutes
The idea of visiting the doctor's office with symptoms of an illness and leaving with a scientifically confirmed diagnosis is much closer to reality because of new technology developed by researchers at McMaster University......»»
Newly discovered trick used by MRSA superbug may aid vaccine development
New research has uncovered a novel trick employed by the bacterium Staphylococcus aureus to thwart the immune response, raising hopes that a vaccine that prevents deadly MRSA infections is a little closer on the horizon......»»
Identification of two pathways for SARS-CoV-2 entry into cells
SARS-CoV-2 is the virus that has caused the COVID-19 pandemic. Ideally, to prevent its spread, treatments should target the early stages of infection before the virus penetrates cells. A joint investigation by INRAE and Heidelberg University, Germany.....»»
A Hospital Algorithm Designed To Predict a Deadly Condition Misses Most Cases
Epic Systems' algorithm for identifying signs of sepsis, an often deadly complication from infections that can lead to organ failure, doesn't work as well as advertised, according to a new study published in JAMA Internal Medicine. The Verge reports:.....»»
First wave COVID-19 data underestimated pandemic infections
Two COVID-19 pandemic curves emerged within many cities during the one-year period from March 2020 to March 2021......»»
Tree pollen carries SARS-CoV-2 particles farther, facilitates virus spread
Most models explaining how viruses are transmitted focus on viral particles escaping one person to infect a nearby person. A study on the role of microscopic particles in how viruses are transmitted suggests pollen is nothing to sneeze at......»»
Engineering nanobodies as lifesavers when SARS-CoV-2 variants attack
