LA JOLLA, CA--Even before the COVID-19 pandemic, most people in the United States already had been sick with a coronavirus, albeit a far less dangerous one. That's because at least four coronaviruses in the same general family as SARS-CoV-2 cause the benign yet annoying illness known as the common cold.

Viruses are perfect molecular machines. Their only goal is to insert their genetic material into healthy cells and thus multiply. With deadly precision, they thereby can cause diseases that cost millions of lives and keep the world on edge. One example for such a virus, although currently less discussed, is HIV that causes the ongoing global AIDS-epidemic. Despite the progress made in recent years, 690 000 people died in 2019 alone as a result of the virus infection.
People living in deprived, less affluent neighborhoods spent less time indoors at home during lockdown, according to a study that tracked data from millions of mobile phone users across the United States.
A new study exploits the characteristic epigenetic signatures of childhood tumors to detect, classify and monitor the disease. The scientists analyzed short fragments of tumor DNA that are circulating in the blood. These "liquid biopsy" analyses exploit the unique epigenetic landscape of bone tumors and do not depend on any genetic alterations, which are rare in childhood cancers. This approach promises to improve personalized diagnostics and, possibly, future therapies of childhood tumors such as Ewing sarcoma. The study has been published in Nature Communications.
Researchers from Tulane University and University of Maryland published a new paper in the Journal of Marketing that examines the dynamic interplay between free and paid versions of an app over its lifetime and suggests a possible remedy for the failure of apps.
The study, forthcoming in the Journal of Marketing, is titled "Managing the Versioning Decision over an App's Lifetime" and is authored by Seoungwoo Lee, Jie Zhang, and Michel Wedel.
Artificial intelligence (AI) technology developed by researchers at the University of Waterloo is capable of assessing the severity of COVID-19 cases with a promising degree of accuracy.
A study, which is part of the COVID-Net open-source initiative launched more than a year ago, involved researchers from Waterloo and spin-off start-up company DarwinAI, as well as radiologists at the Stony Brook School of Medicine and the Montefiore Medical Center in New York.
The next generation of electric vehicle batteries, with greater range and improved safety, could be emerging in the form of lithium metal, solid-state technology.
But key questions about this promising power supply need to be answered before it can make the jump from the laboratory to manufacturing facilities, according to University of Michigan researchers. And with efforts to bring electric vehicles to a larger part of the population, they say, those questions need answering quickly.

The technology using DNA-based genealogy that solved a double murder in Linköping opens completely new possibilities in investigating serious crime. LiU researchers are now involved in spreading new knowledge about the technology, which brings hope to police forces and has aroused major international interest.
"We want to tell others about the problems that we faced when working with this pilot case, and how we dealt with them. We can prevent others reinventing the wheel, and make sure that the knowledge available is extended and improved", says Andreas Tillmar.
University of Virginia School of Medicine researchers have shed new light on how our brains develop, revealing that the very last step in cell division is crucial for the brain to reach its proper size and function.
Corona Virus Disease (COVID -19) patients primarily appear with respiratory issues and viral pneumonia. The patients may also present cardiovascular issues includes early signs of acute myocardial injury. The researchers from Sohag University, Egypt, found that cardiac troponin I (cTnI) can prove to be a gold-standard biomarker for necrosis and myocardial risk assessment in COVID-19 sufferers.
Nearly three years after the Trump administration's "Zero Tolerance" policy went into effect, more than 445 children remain separated from their families, largely due to insufficient identifying paperwork and U.S. immigration officials' failures to plan, track and reunite separated families.
A cutting-edge digital tool that will make it cheaper, safer and faster for pharmaceutical companies to predict protein stability - a vital step in the development of new medicines - is being rolled out by scientists from the UK's University of Bath through their spin-out company, BLOC Labs.
The tool, launched this week, will help researchers identify the most promising protein molecules for drug development. It has the potential to play an important role in the creation of monoclonal antibodies (mAbs). The market for these therapeutic antibodies is worth over £70 bn.
PULLMAN, Wash. - For decades, wealthy nations have transported plastic trash, and the environmental problems that go with it, to poorer countries, but researchers have found a potential bright side to this seemingly unequal trade: plastic waste may provide an economic boon for the lower-income countries.
