(Philadelphia, PA) - The COVID-19 pandemic has increasing numbers of doctors caring for patients virtually. While critical to protecting patient health during a pandemic, however, virtual care presents unique challenges, especially when it comes to diagnosis. Now, cardiologists at the Lewis Katz School of Medicine at Temple University (LKSOM), have come up with a virtual screening tool that greatly simplifies the process of diagnosing a complex form of heart failure known as pulmonary hypertension.

The vast majority of Twitter users who vape with JUUL e-cigarettes are not using the devices to stop smoking or to improve their health, according to a research team led by University of Utah Health scientists. The researchers say this finding, which challenges JUUL's stated mission of improving smokers' lives, could help hone anti-smoking and vaping efforts targeted at Twitter users, particularly underage teens.

WASHINGTON -- Scientists and researchers at the U.S. Naval Research Laboratory and National Center for Advancing Translational Sciences (NCATS), submitted their findings to ACS Nano, a monthly peer-reviewed scientific journal, on their collaboration to develop SARS-CoV-2 nanoparticle probes that are used to study fundamental interactions between SARS-CoV-2 Spike proteins and human cells.

How much time does a brain need to learn a new word? A team of Skoltech researchers and their colleagues monitored changes in brain activity associated with learning new words and found that cortical representations of the sound and meaning of these words may form in just 1 to 2 hours after exposure without any night's sleep consolidation, as earlier research suggested. This research has implications for diagnosing speech disorders and improving the efficiency of learning. The paper was published in the journal Frontiers in Neuroscience.

September 17, 2020 - SEOUL, South Korea - A new study conducted by IVI in collaboration with SK bioscience shows that single-dose and two-dose regimens of Vi-DT typhoid conjugate vaccine (TCV) are safe and immunogenic in children 6-23 months of age, a group with high rates of typhoid fever in resource-limited settings.

A Rutgers-led team has created a smart drug delivery system that reduces inflammation in damaged nervous tissues and may help treat spinal cord injuries and other neurological disorders.

The system, which uses extremely thin biomaterials implanted in the body, also protects nerve fibers (axons) that connect nerve cells in injured neural tissues, according to a study in the journal Advanced Materials.

Children who take oral steroids to treat asthma or autoimmune diseases have an increased risk of diabetes, high blood pressure, and blood clots, according to Rutgers researchers.

For most vertebrates, losing a limb is permanent, but a lucky few species -- such as salamanders and tadpoles -- have the ability to completely regrow complex body parts. Understanding the molecular mechanisms underlying this phenomenon may be the key to developing new kinds of regenerative medicine, giving us the power to heal spinal cord injuries and other severely damaged tissues.

(LOS ANGELES) - Patients with chronic kidney disease and end-stage renal disease have to go to a dialysis center for hours at a time, several times a week for the rest of their lives. Patients on dialysis have strict dietary restrictions, and have difficulty maintaining a job or school with all of the hours that are spent at the dialysis center each week. Often, dialysis is the main treatment doctors tell patients about, so patients go along with it. However, a living donor kidney transplant is the most effective treatment for end-stage renal disease.

An Australian collaboration has reviewed the fundamental theories underpinning the quantum anomalous Hall effect (QAHE).

QAHE is one of the most fascinating and important recent discoveries in condensed-matter physics.

It is key to the function of emerging 'quantum' materials, which offer potential for ultra-low energy electronics.

QAHE causes the flow of zero-resistance electrical current along the edges of a material.

QAHE IN TOPOLOGICAL MATERIALS: KEY TO LOW-ENERGY ELECTRONICS

Researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) in collaboration with colleagues from the Pavlov University, ITMO University, and the University of Hamburg compared their developed carriers for delivery of genome editing (GE) tools with other available analogues. The research of current studies were published in the in the journal Biomaterials.

Researchers at the Norwegian University of Science and Technology (NTNU) have found a completely new method to check the electronic properties of oxide materials. This opens the door to even tinier components and perhaps more sustainable electronics.

"We found a completely new way to control the conductivity of materials at the nanoscale," says Professor Dennis Meier at NTNU's Department of Materials Science and Engineering.

Researchers from Tokyo Medical and Dental University (TMDU) use mouse embryonic stem cells to engineer three-dimensional functional heart organoids resembling the developing heart

Tokyo, Japan -Heart development as it happens in vivo, or in a living organism, is a complex process that has traditionally been difficult to mimic in vitro, or in the laboratory. In a new study, researchers from Tokyo Medical and Dental University (TMDU) developed three-dimensional functional heart organoids from mouse embryonic stem cells that closely resemble the developing heart.

Low-dimensional perovskite-related metal halides have emerged as a new class of light-emitting materials with tunable broadband emission from self-trapped excitons (STEs). Although various types of low-dimensional structures have been developed, fundamental understating of the structure-property relationships for this class of materials is still very limited, and further improvement of their optical properties remains greatly important.

Researchers have shown how industries could work together to recycle cigarette butts into bricks, in a step-by-step implementation plan for saving energy and solving a global littering problem.

Over 6 trillion cigarettes are produced each year globally, resulting in 1.2 million tonnes of toxic waste dumped into the environment.
