2021-06-25
(Press-News.org) What The Study Did: Researchers looked at whether age-related hearing impairment among older adults is associated with poorer and faster decline in physical function and reduced walking endurance.

Authors: Pablo Martinez-Amezcua, M.D., Ph.D., M.H.S., of the Johns Hopkins Bloomberg School of Public Health in Baltimore, is the corresponding author.

TPU scientists synthetize unique molecule of verdazyl-nitronyl nitroxide triradical

2021-06-25
Scientists of Tomsk Polytechnic University jointly with their colleagues have synthetized a unique molecule of verdazyl-nitronyl nitroxide triradical. Only several research teams in the world were able to obtain molecules with similar properties. The molecule is stable. It is able to withstand high temperatures and obtains promising magnetic properties. It is a continuation of scientists' work on the search for promising organic magnetic materials. The research findings are published in the Journal of the American Chemical Society (IF: 14.612, Q1). Magnetoresistive random-access memory (MRAM) is one of the most promising technologies for storage devices. ...

Scientists discover key player in brain development, cell communication

Scientists discover key player in brain development, cell communication
2021-06-25
CHAPEL HILL, NC - When we think of the brain, we think of neurons. But much of the brain is made of non-neuronal cells called glial cells, which help regulate brain development and function. For the first, time UNC School of Medicine scientist Katie Baldwin, PhD, and colleagues revealed a central role of the glial protein hepaCAM in building the brain and affecting brain function early in life. The findings, published in Neuron, have implications for better understanding disorders, such as autism, epilepsy, and schizophrenia, and potentially for creating therapeutics for conditions such as the progressive brain disorder megalencephalic ...

An educational intervention can help vapers use their e-cigarettes to quit smoking

2021-06-25
TAMPA, Fla. -- E-cigarettes spark many concerns, especially when it comes to youth vaping. However, emerging evidence suggests that e-cigarettes can be a helpful tool in smoking cessation. Researchers in Moffitt Cancer Center's Tobacco Research and Intervention Program wanted to build upon this evidence by testing whether they could help dual users, people who use both combustible cigarettes and e-cigarettes, quit smoking. In a new article published in The Lancet Public Health, they report results from a first-of-its kind nationwide study evaluating a targeted intervention aimed at transforming dual users' e-cigarettes from a product that might ...

Scientists discover how dengue vaccine fails to protect against disease

2021-06-25
CHAPEL HILL, NC - Developing a viable vaccine against dengue virus has proved difficult because the pathogen is actually four different virus types, or serotypes. Unless a vaccine protects against all four, a vaccine can wind up doing more harm than good. To help vaccine developers overcome this hurdle, the UNC School of Medicine lab of Aravinda de Silva, PhD, professor in the UNC Department of Microbiology and Immunology, investigated samples from children enrolled in a dengue vaccine trial to identify the specific kinds of antibody responses that correlate with ...

Putting functional proteins in their place

Putting functional proteins in their place
2021-06-25
UPTON, NY--Scientists have organized proteins--nature's most versatile building blocks--in desired 2-D and 3-D ordered arrays while maintaining their structural stability and biological activity. They built these designer functional protein arrays by using DNA as a programmable construction material. The team--representing the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Columbia University, DOE's Lawrence Berkeley National Laboratory, and City University of New York (CUNY)--described their approach in the June 17 issue of Nature Communications. "For decades, scientists have dreamed about rationally assembling proteins into specific organizations with preserved protein function," ...

Bigger may not always be better: Density governs receptor activation on immune cells

Bigger may not always be better: Density governs receptor activation on immune cells
2021-06-25
Scientists from within the Antibody and Vaccine Group at the University of Southampton have gained novel insights into how an important class of immune receptors called tumour necrosis factor receptors (TNFR) are activated. The work, published in the journal Communications Biology, investigates a class of receptors present on immune cells called TNFR. These receptors, such as CD40, 4-1BB and OX40, are key in helping the immune system fight pathogens and cancer cells. Accordingly, antibody drugs which are designed to specifically target and activate these receptors (called ...

Having the same nurse for home health visits may prevent rehospitalization for people with dementia

2021-06-25
People with dementia receiving home health care visits are less likely to be readmitted to the hospital when there is consistency in nursing staff, according to a new study by researchers at NYU Rory Meyers College of Nursing. The findings are published in the journal Medical Care, a journal of the American Public Health Association. Home health care--in which health providers, primarily nurses, visit patients' homes to deliver care--has become a leading source of home- and community-based services caring for people living with dementia. These individuals often have multiple chronic conditions, take several medications, and need assistance with activities of daily living. In 2018, more than 5 million Medicare beneficiaries received ...

People across the world favor paid parental leave, study finds

2021-06-25
COLUMBUS, Ohio - Although the United States is the only wealthy nation that doesn't guarantee paid leave to mothers or fathers after the arrival of a new child, Americans endorse providing paid time off for parents nearly as much as people from other countries. About 82% of Americans support paid maternity leave, just slightly less than the 86% who support it in 26 wealthy nations, a new study shows. Where Americans differ from the rest of the world is that they are less supportive of government funding for paid leaves, prefer shorter leave times and are less supportive of paid leave for fathers. "We find marked differences in how Americans want paid leave administered compared ...

Throwing an 'axion bomb' into a black hole challenges fundamental law of physics

2021-06-25
Singularities such as those at the centre of black holes, where density becomes infinite, are often said to be places where physics 'breaks down'. However, this doesn't mean that 'anything' could happen, and physicists are interested in which laws could break down, and how. Now, a research team from Imperial College London and the Cockcroft Institute and Lancaster University have proposed a way that singularities could violate the law of conservation of charge. Their theory is published in Annalen der Physik. Co-author Professor Martin McCall, from the Department of Physics at Imperial, said: "'Physics breaks down at a singularity' is one of the most famous statements in pop-physics. But by ...

Argonne researchers use AI to optimize a popular material coating technique in real time

2021-06-25
To make computer chips, technologists around the world rely on atomic layer deposition (ALD), which can create films as fine as one atom thick. Businesses commonly use ALD to make semiconductor devices, but it also has applications in solar cells, lithium batteries and other energy-related fields. Today, manufacturers increasingly rely on ALD to make new types of films, but figuring out how to tweak the process for each new material takes time. Part of the problem is that researchers primarily use trial and error to identify optimal growth conditions. But a recently published study -- one of the first in this scientific field -- suggests that using artificial intelligence (AI) can be more efficient. In the ACS Applied ...
