Researchers identify 'clear changes' in aging brain using novel techniques

Researchers investigating brain activity in older people say the coordination between neuronal activity and the brain's oxygenation is altered. Non-invasive recording of the function of these neurovascular units in living humans has never been done before, but has now been achieved by using several measurement techniques coupled with novel analysis methods. The results promise a relatively simple and non-invasive method for assessing the state of the brain in healthy aging, and in neurodegenerative disorders such as Alzheimer's disease.

Obesity associated with consumption of ultra-processed food along with thousands of potential environmental toxins

World-wide obesity has nearly tripled since 1975, according to the World Health Organization. Numerous causes of obesity have been hypothesized including increased dietary fat, carbohydrate or ultra-processed food (UPF) consumption, inactivity, hyperlipidemia and hyperinsulinemia. Based on these hypotheses, solutions have been sought that involved decreasing consumption of suspected agents. Well-controlled studies have shown that increased consumption of UPF is associated with increased food consumption and weight gain while decreasing UPF consumption in the same subjects was associated with weight loss. However, these studies do not identify a specific cause of obesity since the diets include multiple variables. Researchers now present an alternative testable and actionable hypothesis/model about the cause of obesity. If validated, it could indicate clear steps to reverse obesity.

How eavesdropping viruses battle it out to infect us

Dozens of viruses -- at least -- can eavesdrop on host information. Not only did they demonstrate the strategy's abundance, but they also discovered tools that control it and send signals that tell bacteriophage viruses to flip from chill (lysogeny) into kill (lysis) mode. They showed that in polylysogeny, phages can coexist, their viral DNA or RNA hidden tucked inside the bacterium's own, replicating right along with the cells. But the infiltrating phages aren't exactly peaceful; it's more like mutually assured destruction. And the tenuous detente lasts only until something triggers one or more of the phages to switch into kill mode.

Researchers generate human embryo-like structures that include extraembryonic tissue

Gastrulation, the process where an embryo reorganizes itself from a hollow sphere into a multilayered structure, is considered a 'black box' of human development. This is because human embryos are typically not cultured for longer than 14 days because of bioethical concerns, and gastrulation occurs between 17- and 21-days post-fertilization. In addition, current stem cell models that mimic gastrulation have not been able to include the necessary extraembryonic tissues that give rise to the yolk sac and the placenta. Researchers now report a new method to develop 'peri-gastruloids,' an embryo-like structure that includes one of the supporting tissues, the yolk sac, missing from previous models.

Simply the smell of seafood can make those with an allergy to it violently ill -- and therefore more likely to avoid it. The same avoidance behavior is exhibited by people who develop food poisoning after eating a certain meal. Scientists have long known that the immune system played a key role in our reactions to allergens and pathogens in the environment, but it was unclear whether it played any role in prompting these types of behaviors towards allergic triggers.

Taking a lesson from spiders: Researchers create an innovative method to produce soft recyclable fibers for smart textiles

Researchers drew inspiration from the spider silk spinning process to fabricate strong, stretchable, and electrically conductive soft fibers. Their novel technique overcomes the challenges of conventional methods, which require complex conditions and systems. Such soft and recyclable fibers have a wide range of potential applications, such as a strain-sensing glove for gaming or a smart mask for monitoring breathing status for conditions such as obstructive sleep apnea.

AI nursing ethics: Viability of robots and artificial intelligence in nursing practice

Robots and artificial intelligence (AI) are expected to play a key role in nursing practice in the future. In this regard, researchers from Japan ask whether intelligent machines can replace humans as nurses. They investigate the potential of current advancements in robotics and AI to replicate the ethical concepts attributed to nurses, including advocacy, accountability, cooperation, and caring. While these technologies hold promise in enhancing healthcare practices, their integration into nursing requires careful consideration.

First bioavailable compound that specifically inhibits free radical production in mitochondria prevents and treats metabolic syndrome in mice

The free radical theory of aging is back in play after falling out of favor decades ago. (Remember when people were taking massive doses of various vitamins and minerals? Mopping up free radicals with antioxidants compromised beneficial metabolic signaling pathways leading to bad side effects). What brings the theory back? Researchers at the Buck discovered that they could specifically block free radical production in mitochondria. An elegant solution replaces an indiscriminate and messy mop up. These scientists developed a bioavailable compound -- available in a pill form -- that blocks free radical production. The compound both prevented and treated metabolic syndrome in mice. 'We think that mitochondrial radical production drives many chronic diseases of aging, and that blocking the production of free radicals is a viable disease-treating and anti-aging intervention,' said Martin Brand, Ph.D., Buck Professor Emeritus and senior investigator of the study.

A new study shows the sugar sialic acid, which makes up part of the protective intestinal mucus layer, fuels disease-causing bacteria in the gut. The findings suggest a potential treatment target for intestinal bacterial infections and a range of chronic diseases linked to gut bacteria, including inflammatory bowel disease (IBD), celiac disease, irritable bowel syndrome and short bowel syndrome.

Older adults who remain more active have a better quality of life study finds

A reduction in the amount of time spent physically active when adults are over sixty years old is linked to lower quality of life, a new study of almost 1,500 adults has shown. The same was also true for increases in the amount of sedentary time, such as watching TV or reading. The researchers say this highlights the need to encourage older adults to remain active.

How the ear can inform the brain of whether hearing is impaired

A cochlear signal, the exact role of which has been unclear since its discovery around 70 years ago, probably gives the brain information on whether the ear is functioning normally or not. These new findings are an important piece of the puzzle in explaining what happens in the ear in hearing impairment caused by harmful noise, and may in the long run contribute to diagnosing noise-induced hearing injury.

How mercury emissions from industry can be greatly reduced

Sulphuric acid is the world's most used chemical. It is an important reagent used in many industries and it is used in the manufacture of everything from paper, pharmaceuticals and cosmetics to batteries, detergents and fertilizers. It is therefore a worldwide challenge that sulphuric acid often contains one of the most toxic substances -- mercury. Researchers have now developed a method that can reduce the levels of mercury in sulphuric acid by more than 90 per cent -- even from low levels.
