New study challenges long-standing assumptions about disease severity in infants, and suggests that standard qPCR interpretations underestimate the true burden of other highly contagious diseases, such as COVID-19 and influenza.
Pertussis, also known as "whooping cough," remains a significant cause of death in infants and young children around the world and, despite global vaccination programs, many countries are experiencing a resurgence of this highly contagious disease.
UTICA, NY -- More than 2 million coronary artery stents are implanted each year to help protect or restore normal blood flow to the heart, to treat patients suffering from angina or a heart attack due to coronary artery disease (CAD). While stents are highly effective and safe devices, scarring or clotting of unhealed stents can occur in a small percentage of subjects, leading to complications such as stent restenosis or thrombosis, which can be life-threatening. At present, approaches to understand stent healing based on their biological clotting status is unavailable in patients.
Type 1 diabetes is a disorder in which the immune system inappropriately targets a class of cells in the pancreas known as β cells that produce the hormone insulin, which plays an important role in regulating bloodstream glucose levels and the metabolism of carbohydrates, lipids, and proteins. The loss of insulin causes a range of health problems for people with type 1 diabetes, and patients become dependent on insulin injections for their survival.
New technologies allow users to do things like race their real bikes against other real people in a virtual world, and a new study outlines what motivates people to use these online platforms. The findings offer insights for future iterations of these technologies - and how to market them.
When astronomers using NASA's Hubble Space Telescope uncovered an oddball galaxy that looked like it didn't have much dark matter, some thought the finding was hard to believe and looked for a simpler explanation.
Dark matter, after all, is the invisible glue that makes up the bulk of the universe's matter. All galaxies appear to be dominated by it; in fact, galaxies are thought to form inside immense halos of dark matter.
The intestinal disease necrotizing enterocolitis is a leading cause of death among premature infants born in the U.S. and across the globe. Characterized by excessive inflammation that can cause tissue decay in the bowels, the disease provides a pathway for infectious and deadly bacteria to enter the bloodstream.
Despite four decades of research, effective treatments remain elusive, and mortality rates in babies who develop the disease have remained essentially unchanged, hovering at about 30%.
TAMPA, Fla. (June 17, 2021) - Tests that analyze biomarkers are used during cancer management to guide treatment and provide information about patient prognosis. These tests are often performed on tissue biopsy samples that require invasive procedures and can lead to significant side effects.
The Black Sea is an unusual body of water: below a depth of 150 metres the dissolved oxygen concentration sinks to around zero, meaning that higher life forms such as plants and animals cannot exist in these areas. At the same time, this semi-enclosed sea stores comparatively large amounts of organic carbon. A team of researchers led by Dr Gonzalo V.
Woodlands along streams and rivers are an important part of California's diverse ecology. They are biodiversity hotspots, providing various ecosystem services including carbon sequestration and critical habitat for threatened and endangered species. But our land and water use have significantly impacted these ecosystems, sometimes in unexpected ways.
SAN ANTONIO (June 17, 2021) -- Middle-aged people with depressive symptoms who carry a genetic variation called apolipoprotein (APOE) ε4 may be more at risk to develop tau protein accumulations in the brain's emotion- and memory-controlling regions, a new study by researchers from The University of Texas Health Science Center at San Antonio (UT Health San Antonio) and collaborating institutions suggests.
Nanodecoys made from human lung spheroid cells (LSCs) can bind to and neutralize SARS-CoV-2, promoting viral clearance and reducing lung injury in a macaque model of COVID-19. By mimicking the receptor that the virus binds to rather than targeting the virus itself, nanodecoy therapy could remain effective against emerging variants of the virus.
TROY, N.Y. -- Optoelectronic materials that are capable of converting the energy of light into electricity, and electricity into light, have promising applications as light-emitting, energy-harvesting, and sensing technologies. However, devices made of these materials are often plagued by inefficiency, losing significant useful energy as heat. To break the current limits of efficiency, new principles of light-electricity conversion are needed.
The article 'The RNA Atlas expands the catalog of human non-coding RNAs', published today in Nature Biotechnology, is the result of more than five years of hard work to further unravel the complexity of the human transcriptome. Never before such a comprehensive effort was undertaken to characterize all RNA-molecules in human cells and tissues.
RNAs in all shapes and sizes
Additive manufacturing offers an unprecedented level of design flexibility and expanded functionality, but the quality and process can drastically differ across production machines, according to Hui Yang, a professor of industrial engineering at Penn State. With applications in aerospace, health care and automotive industries with potential for mass customization, additive manufacturing needs quality management.
CAMBRIDGE, MA--Geothermal energy systems have the potential to power the world and become the leading technology for reducing greenhouse gas emissions if we can drill down far enough into the Earth to access the conditions necessary for economic viability and release the heat beneath our feet. Quaise Inc. is developing a potentially disruptive and completely unique drilling technology to make that happen.
