Objectively measured visual impairment and dementia prevalence in older adults

JAMA Ophthalmology

2023-07-13

(Press-News.org) About The Study: In this survey study, all types of objectively measured visual impairment were associated with a higher dementia prevalence. As most visual impairment is preventable, prioritizing vision health may be important for optimizing cognitive function.

Authors: Joshua R. Ehrlich, M.D., M.P.H., of the University of Michigan in Ann Arbor, is the corresponding author.

How COVID-19 crosses the placenta - study using placental tissue grown in the lab

2023-07-13

RESEARCH REVEALS HOW COVID-19 VIRUS INFECTS THE PLACENTA, AND HOW THIS CAN BE PREVENTED In a landmark study published in Nature Cell Biology, Australian researchers, led by Professor Jose Polo from Monash University and the University of Adelaide and University of Melbourne’s Professor Kanta Subbarao from the Peter Doherty Institute for Infection and Immunity (Doherty Institute), have revealed how COVID-19 can infect the human placenta. Research has shown that COVID-19 infections during pregnancy ...

The timekeeper within: New discovery on how the brain judges time

2023-07-13

From Aristotle’s musings on the nature of time to Einstein’s theory of relativity, humanity has long pondered: how do we perceive and understand time? The theory of relativity posits that time can stretch and contract, a phenomenon known as time dilation. Just as the cosmos warps time, our neural circuits can stretch and compress our subjective experience of time. As Einstein famously quipped, “Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute”. In new work ...

Tau-based biomarker tracks Alzheimer’s progression

2023-07-13

Two pathologies drive the progression of Alzheimer’s disease. Early on, amyloid beta plaques lead the way, but around the time cognitive symptoms arise, tau tangles take over as the driving force and cognition steadily declines. Tracking the course of the disease in individual patients has been challenging because there’s been no easy way to measure tau tangles in the brain. But now, researchers at Washington University School of Medicine in St. Louis and Lund University in Lund, Sweden, have identified a form of tau that could serve as a marker to track Alzheimer’s progression. The marker also could be used by Alzheimer’s drug developers to assess ...

Engineering dual carriageways for signals

2023-07-13

Routing signals and isolating them against noise and back-reflections are essential in many practical situations in classical communication as well as in quantum processing. In a theory-experimental collaboration, a team led by Andreas Nunnenkamp from the University of Vienna and Ewold Verhagen based at the research institute AMOLF in Amsterdam has achieved unidirectional transport of signals in pairs of "one-way streets". This research published in Nature Physics opens up new possibilities for more flexible signaling devices. Devices that allow ...

In historic procedure, donor liver protects heart transplant

2023-07-13

Doctors in Seattle are reporting a history-making case in which a patient received two donor organs, a liver and a heart, to prevent the extreme likelihood that her body would reject a donor heart transplanted alone. In this innovative case, the organ recipient’s own healthy liver was transplanted, domino-like, into a second patient who had advanced liver disease. The dual-organ recipient, Adriana Rodriguez, 31, of Bellingham, Washington, has recovered well since the Jan. 14, 2023, procedures, said Dr. Shin Lin, a cardiologist ...

Red pill or blue pill? The critical decision to control the superbugs

2023-07-13

Researchers from Tokyo Medical and Dental University (TMDU) investigate a pharmacist-led intervention to optimize the oral antimicrobial prescriptions in dental setting Tokyo, Japan - The battle to stop the increase of superbugs in hospitals has been an ongoing struggle for healthcare professionals. Dentists are currently facing a medical challenge that determines the faith of antimicrobial resistance in healthcare settings. To choose the “red pill” means to embrace the painful truth that bacteria are acquiring resistance to many antimicrobials. Meanwhile, the “blue pill” creates ...

The economic life of cells

2023-07-13

A team from the University of Tokyo has combined economic theory with biology to understand how natural systems respond to change. The researchers noticed a similarity between consumers’ shopping behavior and the behavior of metabolic systems, which convert food into energy in our bodies. The team focused on predicting how different metabolic systems might respond to environmental change by using an economic tool called the Slutsky equation. Their calculations indicated that very different metabolic ...

Researchers propose strategy for improving NASICON-type cathode performance

2023-07-13

Manganese-rich NASICON-type materials have attracted widespread attention for developing advanced polyanionic cathodes, primarily driven by their abundant reserves, promising cycling performance, and potentially high operating voltage. Unfortunately, their charge/discharge profiles exhibit significant voltage hysteresis, which leads to a limited reversible capacity, thereby preventing their application. Now, however, the situation may be changing due to research by scientists at the Institute of Process Engineering (IPE) and the Institute of Physics of the Chinese Academy of Sciences. They recently identified ...

Drexel’s titanium oxide material lets sunlight drive green hydrogen production

2023-07-13

Clean energy plans, including the U.S. Infrastructure Investment Act’s “Clean Hydrogen Road Map,” are counting on hydrogen as a fuel of the future. But current hydrogen separation technology is still falling short of efficiency and sustainability goals. As part of ongoing efforts to develop materials that could enable alternative energy sources, researchers in Drexel University’s College of Engineering have produced a titanium oxide nanofilament material that can harness sunlight to unlock the ubiquitous molecule’s potential as a fuel source. The discovery offers an alternative ...

Advancing causal inference in clinical neuroscience research: a call for clarity

2023-07-13

A Perspective published in Volume 3 of the journal Psychoradiology, researchers from Shanghai Jiao Tong University confronted these challenges and advocates for more clarity and transparency in causal analyses. The review distinguishes between traditional statistical analysis and causal inference, highlighting the need for specific causal assumptions, like the Stable Unit Treatment Value Assumption (SUTVA). Randomized controlled trials (RCTs) are considered the gold standard for estimating causal effects. The authors stress the importance of imitating RCTs in observational studies through quasi-experimental techniques, ...
