The absence of a 2020-21 flu season shows how effective simple public health measures are at limiting virus transmission — ScienceDaily


If you did not catch the flu this year — and there is an overwhelming chance that you did not — you have COVID-19 to thank. It’s a small consolation, given the enormously disruptive scope of the pandemic. But it’s the focus of a new paper published in the journal Frontiers in Public Health by […]

Coronavirus: Mixing and matching Pfizer and AstraZeneca jabs ‘could worsen side effects’


Mixing and matching Covid vaccines could lead to more side effects, scientists say. British guidance says people should be given two doses of the same jab because of a lack of data on alternating doses. But there are ongoing trials of giving one type for the first dose and a different type for the second, […]

The study appeared in the journal Nature Communications. Several […]

New Strep A human challenge model paves the way to test vaccines against the deadly bacteria — ScienceDaily


Researchers have successfully developed a new Strep A human challenge model, paving the way to test vaccines against the common deadly bacteria that causes sore throats, scarlet fever and skin sores. The collaborative research effort, led by the Murdoch Children’s Research Institute (MCRI) and published in The Lancet Microbe, found the model, which deliberately infected […]

Smartphone breath alcohol testing devices vary widely in accuracy — ScienceDaily


Alcohol-impaired driving kills 29 people a day and costs $121 billion a year in the U.S. After years of progress in reducing alcohol-impaired driving fatalities, efforts began to stall in 2009, and fatalities started increasing again in 2015. With several studies demonstrating that drinkers cannot accurately estimate their own blood alcohol concentration (BAC), handheld alcohol […]

Vegetarians have healthier levels of disease markers than meat-eaters — ScienceDaily


Vegetarians appear to have a healthier biomarker profile than meat-eaters, and this applies to adults of any age and weight, and is also unaffected by smoking and alcohol consumption, according to a new study in over 166,000 UK adults, being presented at this week’s European Congress on Obesity (ECO), held online this year. Biomarkers can […]

Small study shows heart damage after COVID-19 uncommon in college athletes — ScienceDaily


In a small study, researchers found college athletes who contracted COVID-19 rarely had cardiac complications. Most had mild COVID symptoms that did not require treatment, and in a small percentage of those with abnormal cardiac testing, there was no evidence of heart damage on special imaging tests. All athletes returned to sports without any health […]

Undetected early heart damage raises risk of death in hospitalized COVID-19 patients — ScienceDaily


Hospitalized COVID-19 patients with impaired first-phase ejection fraction were nearly 5 times more likely to die compared to patients with healthier measures of this early, often undetected sign of heart failure, according to new research published today in Hypertension, an American Heart Association journal. First-phase ejection fraction is a measure of the left ventricular ejection […]

Household carbon footprints did not significantly change during the first state of emergency in Japan — ScienceDaily


Despite the rapid and significant changes in consumption patterns witnessed during the initial months of the COVID-19 pandemic, Japanese households maintained their normal levels of greenhouse gases emissions. The “anthropause” — reduction of human activity due to the pandemic — made headlines last summer, but factory shutdowns and broken global supply chains did not translate […]

Study examined response to films like ‘Hotel Rwanda’ and ‘Up’ — ScienceDaily


Watching meaningful films — those that we find moving and poignant — can make us feel more prepared to deal with life’s challenges and want to be a better person, a new study found. The findings point to one reason why people may choose to see movies that make them sad as well as happy […]

Esophageal cancers resurrect ancient retroviruses hidden in our genome — ScienceDaily


Scientists have discovered that many esophageal cancers turn on ancient viral DNA that was embedded in our genome hundreds of millions of years ago. “It was surprising,” says Adam Bass, MD, the Herbert and Florence Irving Professor of Medicine at Columbia University Vagelos College of Physicians and Surgeons and Herbert Irving Comprehensive Cancer Center, who […]

New finding suggests cognitive problems caused by repeat mild head hits could be treated — ScienceDaily


A neurologic pathway by which non-damaging but high frequency brain impact blunts normal brain function and causes long-term problems with learning and memory has been identified. The finding suggests that tailored drug therapy can be designed and developed to reactivate and normalize cognitive function, say neuroscientists at Georgetown University Medical Center. The investigators, working with […]

Engineering diseased human skin in vitro — ScienceDaily


The skin, which covers the surface of the human body, is its largest organ. It is the first organ to show changes stemming from organ or physiological activity. It is especially common for diabetic patients to suffer from skin diseases or infections. Recently, a POSTECH research team has succeeded in creating a 3D artificial skin […]
