You can save a cardiac arrest victim’s life even if an ambulance arrives in two minutes

Amsterdam, Netherlands – 24 Aug 2023: Using a defibrillator for a cardiac arrest victim improves 30-day survival even with ambulance response times as short as two minutes, according to research presented at ESC Congress 2023.1 The majority of sudden cardiac arrests occur in the community. A cardiac arrhythmia, called ventricular fibrillation, causes the heart to cease pumping and blood flow stops. If blood flow is not restored quickly, the individual passes out and dies within 10 to 20 minutes. Members of the public can help by calling an ambulance and performing chest compressions (called cardiopulmonary resuscitation; CPR) while asking someone else to find a defibrillator. ...

Community-based services could reduce the risk of frailty in older adults with low care needs

Osaka, Japan – Even if you are a lone wolf, considering some group activities may not be a bad idea, especially when it comes to healthcare. Osaka Metropolitan University scientists have found that community-based adult day services help lower the risk of frailty in older adults. Frailty is a state of physical and mental decline that results from aging; it represents an intermediate status between being healthy and being severely disabled. In a rapidly aging society, preventing frailty and maintaining independence in older adults are crucial challenges. “In Japan, older individuals certified as being on a support ...

Father-child bonding and its impact on pediatric developmental outcomes

The early physical and mental development of a child sets the stage for lifelong progress and fulfillment. Spending quality time with their parents can bring out significant positive changes among children during their formative years. Across Japan, the extent of fathers' participation in childcare-related activities has historically been limited because of the entrenched gender-based division of labor. Fathers, especially those in their 20s–40s, are expected to show full commitment towards work and have been prioritizing their professional commitments over family. Consequently, a significant number ...

New pocket-sized device for clinicians could spot infected wounds faster

It’s notoriously difficult for doctors to identify a wound that is becoming infected. Clinical signs and symptoms are imprecise and methods of identifying bacteria can be time-consuming and inaccessible, so a diagnosis can be subjective and dependent on clinician experience. But infection can stall healing or spread into the body if it isn’t treated quickly, putting a patient’s health in grave danger. An international team of scientists and clinicians thinks they have the solution: a device run from a smartphone or tablet app which allows advanced ...

When proteins get stuck at solid: unlocking the secrets to brain diseases

Many diseases affecting the brain and nervous system are linked to the formation of protein aggregates, or solid condensates, in cells from their liquid form condensate, but little is known about this process. This liquid-to-solid transition can trigger the formation of what are called amyloid fibrils. These can further form plaques in neurons causing neurodegenerative diseases such as Alzheimer's. Biomedical engineers at the University of Sydney, in collaboration with scientists at the University of Cambridge ...

Do measurements produce the reality they show us?

Whenever the precision of a measurement approaches the uncertainty limit defined by quantum mechanics, the outcomes of the measurement depend on the dynamics of the interactions with the meter used to determine a physical property of the system. This finding may explain why quantum experiments often produce conflicting results and may contradict basic assumptions regarding physical reality. Two quantum physicists from Hiroshima University recently analyzed the dynamics of a measurement interaction, where the value of a physical property is identified with a quantitative change in the meter state. This is a difficult problem, because quantum theory does not identify the value ...

The mouse metaverse: A tool for understanding the molecular mechanism of autism and the mind

Autism is difficult to study and more difficult to treat because it is an individual condition lacking precise quantification. The development of mouse models of human mental disorders has proven a tractable approach to studying the molecular mechanisms, a new review argues and highlights the current state of the art in autism research. Whether or not the autism spectrum is a disorder to be treated or a disability to be accommodated is debated by experts. This, however, is symptomatic for the fact that it is a very individual condition that has many expressions as well as causes, with no quantitative evaluation system or objective, mechanized diagnostic method. This makes ...

New ‘verbal treasure trove’ dictionary captures nuances and uses of Shakespeare’s words

William Shakespeare used the word dotage to capture reduced mental ability (as in being blindly in love) rather than as a quaint term for old age, successes were really outcomes – one could talk of a ‘bad success’ – and, it turns out, the word bastard back then most often referred to a flower that was genetically hybrid. A new dictionary, a verbal treasure trove of the nuances and uses of Shakespeare’s words, is published this week. While dinner was preferred by Shakespeare for what we might think of as lunch (although his contemporaries used it to refer to an evening meal), beef, as today, was strongly associated with the English, but particularly the lower ...

Blink and you'll miss these plants shooting their seeds

DURHAM, N.C. -- If you happened upon a witch hazel plant in the forest, you might describe it as a sweet-smelling shrub with crinkly ribbon-like petals. But to Duke University graduate student Justin Jorge, it’s a howitzer. That’s because of the impressive firepower of its fruits. When witch hazels are ready to disperse their seeds, their woody seed capsules split open. Pressure builds up, and eventually the seeds shoot out like bullets fired from a rifle, hitting 30 feet per second in about half a millisecond. “If you blink you’ll miss it,” said Jorge, who worked on this project as part of his Ph.D. thesis in biomechanics with senior author ...
