Heart data unlocks sleep secrets

We know that quality sleep is as essential to survival as food and water. Yet, despite spending a third of our lives in slumber, it largely remains a scientific mystery.    Not that experts haven’t tried.   Sleep analysis, also known as polysomnography, is used to diagnose sleep disorders by recording multiple types of data, including brain (electroencephalogram or EEG) and heart (electrocardiogram or ECG). Typically, patients are hooked up to dozens of sensors and wires in a clinic, tracking brain, ...

Development of a model capable of predicting the cycle lives of high-energy-density lithium-metal batteries

1. NIMS and SoftBank Corp. have jointly developed a model capable of predicting the cycle lives of high-energy-density lithium-metal batteries by applying machine learning methods to battery performance data. The model proved able to accurately estimate batteries’ longevity by analyzing their charge, discharge and voltage relaxation process data without relying on any assumption about specific battery degradation mechanisms. The technique is expected to be useful in improving the safety and reliability of devices powered by lithium-metal batteries. 2. Lithium-metal ...

Illinois researchers develop index to quantify circular bioeconomy

URBANA, Ill. – As the world faces the challenges of mitigating climate change and providing resources for a growing population, there is increasing focus on developing circular economies for sustainable production. But to evaluate strategies and impacts, it is necessary to have reliable metrics. Researchers at the University of Illinois Urbana-Champaign have developed a Circularity Index that provides a comprehensive method to quantify circularity in bioeconomic systems. In a new paper, they outline the method and apply it to two case studies – a corn/soybean farming operation and the entire U.S. food and agriculture system. “The ...

Less severe forest fires can reduce intensity of future blazes

Not all forest fires have devastating effects. Low- and moderate-severity forest wildfires can reduce the intensity of future conflagrations for as long as 20 years in certain climates, according to new research by the University of California, Davis.  The extent of reduced severity of these second fires, or reburns, and the duration of the moderating effect, varies by climate, forest type and other factors. But initial fires continue to mitigate future severity even during extreme weather, such as wind, high temperatures and drought, research published in the journal Ecological ...

Electric reactor could cut industrial emissions

Currently, industrial processes in the U.S. account for approximately a third of the country’s carbon dioxide emissions – even more than the annual emissions from passenger vehicles, trucks, and airplanes combined. Decarbonizing this sector is a challenging but vital step in mitigating impacts on our future climate. Researchers at Stanford Engineering have designed and demonstrated a new type of thermochemical reactor that is capable of generating the immense amounts of heat required for many industrial processes using electricity instead of burning fossil fuels. The design, published Aug. ...

Causal relationship between PECAM-1 level and cardiovascular diseases

https://www.scienceopen.com/hosted-document?doi=10.15212/CVIA.2024.0032 Announcing a new article publication for Cardiovascular Innovations and Applications journal. Platelet endothelial cell adhesion molecule (PECAM-1) is present in the vascular endothelium and plays important roles in various biological processes. Several recent studies have reported associations between PECAM-1 and certain subtypes of cardiovascular diseases (CVDs). However, further research is necessary to clarify the causal effects of PECAM-1 on CVDs. To determine whether PECAM-1 and CVDs are causally ...

DCM is defined by a dilated and deficient systolic left ventricle (LV) and is a major risk factor for morbidity and mortality worldwide. DCM progression can be ascribed to genetic and non-genetic factors, including hypertension, infectious agents, toxins, and drugs. Sarcomere genes play crucial roles in myocardial cells’ physical structure and physiological function. Various cardiomyopathies ...

For some older adults with kidney failure, dialysis may not be the best option

Whether dialysis is the best option for kidney failure and, if so, when to start, may deserve more careful consideration, according to a new study. For older adults who were not healthy enough for a kidney transplant, starting dialysis when their kidney function fell below a certain threshold — rather than waiting — afforded them roughly one more week of life, Stanford Medicine researchers and their colleagues found. More critically, perhaps, they spent an average of two more weeks in ...

MIT study explains why laws are written in an incomprehensible style

Legal documents are notoriously difficult to understand, even for lawyers. This raises the question: Why are these documents written in a style that makes them so impenetrable? MIT cognitive scientists believe they have uncovered the answer to that question. Just as “magic spells” use special rhymes and archaic terms to signal their power, the convoluted language of legalese acts to convey a sense of authority, they conclude. In a study that will appear in the journal of the Proceedings of the National Academy of Sciences, the researchers found that even non-lawyers use this type of language when asked to write laws. “People seem to understand that there’s ...

MINNEAPOLIS/ST. PAUL (08/19/2024) — Mindfulness-based interventions delivered via telehealth in a scalable format can improve pain and overall well-being among veterans with chronic pain, according to new research published today in JAMA Internal Medicine.  In a randomized clinical trial, researchers aimed to test the effectiveness of two eight-week telehealth mindfulness-based interventions (MBIs) designed to be scalable and widely implemented in healthcare systems. MBIs help people pay attention non-judgmentally in the present moment and often involve practices like meditation, breathing exercises or gentle movement. “Although mindfulness interventions are evidence-based ...

How "winner and loser effects" impact social rank in animals - and humans

Research has shown that in many animals, the winners of a fight are more likely to win subsequent contests, while the losers tend to lose their following fights. In experiments where male stickleback fish were randomly introduced to another fish, 65% of the winning fish won the second match, while all losing fish lost the second contest. Such winner and loser effects can greatly influence individual behavior and fitness. This effect happens in humans as well. In "Winner and Loser Effects and Social Rank in Humans," recently published in The Quarterly Review of Biology, authors Noah M. T. Smith and Reuven ...

Research study examines Alzheimer’s disease drug on tissue samples from people with Down syndrome

People with Down syndrome are likely to develop Alzheimer’s disease at a young age, with autopsy studies showing that by age 40 years, the brains of individuals with Down syndrome have amyloid plaques. Yet people with Down syndrome have been excluded from or underrepresented in clinical trials of new therapies for treating AD. Lecanemab, which has been shown to target and remove beta-amyloid plaques, has been approved by the U.S. Food and Drug Administration to treat AD early in the disease’s progression. ...

Lifestyle diseases, also known as non-communicable diseases (NCDs), have emerged as a major health burden globally, including in India. These diseases, such as obesity, diabetes, hypertension, cardiovascular diseases, and metabolic disorders, are primarily caused by unhealthy lifestyle choices like sedentary behavior, poor dietary habits, and stress. According to the World Health Organization (WHO), NCDs are responsible for 41 million deaths annually, accounting for 74% of all global deaths. Notably, 86% of these premature deaths occur in low- and middle-income countries. The increasing prevalence of lifestyle diseases ...

Self-adjusting brain pacemaker may help reduce Parkinson’s disease symptoms

A small feasibility study funded by the National Institutes of Health (NIH) found that an implanted device regulated by the body’s brain activity could provide continual and improved treatment for the symptoms of Parkinson’s disease (PD) in certain people with the disorder. This type of treatment, called adaptive deep brain stimulation (aDBS), is an improvement on a technique that has been used for PD and other brain disorders for many years. The study found aDBS was markedly more effective at controlling PD symptoms compared to conventional DBS treatments. “This study marks a big step forward towards ...
