Ancient part of immune system may underpin severe COVID

One of the immune system's oldest branches, called complement, may be influencing the severity of COVID disease, according to a new study from researchers at Columbia University Irving Medical Center. Among other findings linking complement to COVID, the researchers found... Continue Reading →

How COVID-19 causes smell loss

Temporary loss of smell, or anosmia, is the main neurological symptom and one of the earliest and most commonly reported indicators of COVID-19. Studies suggest it better predicts the disease than other well-known symptoms such as fever and cough, but... Continue Reading →

COVID-19 causes ‘hyperactivity’ in blood-clotting cells

Changes in blood platelets triggered by COVID-19 could contribute to the onset of heart attacks, strokes, and other serious complications in some patients who have the disease, according to University of Utah Health scientists. The researchers found that inflammatory proteins... Continue Reading →

Newer variant of COVID-19-causing virus dominates global infections

Research out in the journal Cell shows that a specific change in the SARS-CoV-2 coronavirus virus genome, previously associated with increased viral transmission and the spread of COVID-19, is more infectious in cell culture. The variant in question, D614G, makes a small... Continue Reading →

Children face risk for severe complications and death from COVID-19

Children, teens and young adults are at greater risk for severe complications from COVID-19 than previously thought and those with underlying health conditions are at even greater risk, according to a study coauthored by a Rutgers researcher. The study, published... Continue Reading →

Bat ‘super immunity’ may explain how bats carry coronaviruses, study finds

A University of Saskatchewan (USask) research team has uncovered how bats can carry the Middle East respiratory syndrome (MERS) coronavirus without getting sick -- research that could shed light on how coronaviruses make the jump to humans and other animals.... Continue Reading →

Vitamin D levels appear to play role in COVID-19 mortality rates

After studying global data from the novel coronavirus (COVID-19) pandemic, researchers have discovered a strong correlation between severe vitamin D deficiency and mortality rates. Led by Northwestern University, the research team conducted a statistical analysis of data from hospitals and... Continue Reading →

Key nose cells identified as likely COVID-19 virus entry points

Two specific cell types in the nose have been identified as likely initial infection points for COVID-19 coronavirus. Scientists discovered that goblet and ciliated cells in the nose have high levels of the entry proteins that the COVID-19 virus uses... Continue Reading →

Ultraviolet LEDs prove effective in eliminating coronavirus from surfaces and, potentially, air and water

As COVID-19 continues to ravage global populations, the world is singularly focused on finding ways to battle the novel coronavirus. That includes the UC Santa Barbara's Solid State Lighting & Energy Electronics Center (SSLEEC) and member companies. Researchers there are... Continue Reading →
