Statement Highlights: More than half of people who survive a stroke develop cognitive impairment within the first year after their stroke, and as many as 1 in 3 may develop dementia within 5 years. The high risk of cognitive impairment and dementia after a stroke suggests early screening is essential for determining initial treatment, such as multidisciplinary care, cognitive rehabilitation or increased physical activity. It’s also important to assess stroke survivors for cognitive changes over time to offer appropriate treatment modifications and support for longer-term care. Cognitive impairment after stroke may fluctuate, particularly ...

Different market products give very different results when it comes to liberating the antioxidant lutein from spinach in smoothies. Researchers at Linköping University, Sweden, have examined 14 common dairy and plant-based products and found that only four of these increased lutein liberation. Compared to water, some drinks had a negative effect on the lutein content in spinach smoothies.   Most people know that spinach is good for your health. One substance found in, for instance, spinach and kale is lutein. Several experimental studies have shown that lutein can suppress processes linked to inflammation, and there is now ample research indicating ...

It’s generally accepted we will lose muscle strength and slow down as we age, making it more difficult to perform simple tasks such as getting up, walking and sitting down.   But new Edith Cowan University (ECU) research indicates this could also be a signal for another sinister health concern of ageing: late-life dementia.   To investigate the relationship between muscle function and dementia, the research teams from ECU’s Nutrition & Health Innovation Research Institute and Centre for Precision Health used data from the Perth Longitudinal Study of Ageing in Women to examine more than 1000 women with an average age of 75.   In collaboration with the ...

Does air pollution affect your heart? Acute exposure to air pollution was found to be associated with an increased risk of arrythmia — irregular heartbeat — in a large study of 322 Chinese cities published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.220929. The common arrhythmia conditions atrial fibrillation and atrial flutter, which can progress to more serious heart disease, affect an estimated 59.7 million people globally. Air pollution is a modifiable risk factor for heart disease, but the evidence linking it with ...

The United States is in the midst of a mental health crisis with rising rates of hospitalization for suicide and self-harm events among children and adolescents. A study, “Characteristics Associated with Serious Self-Harm Events in Children and Adolescents,” set to be published in the June issue of Pediatrics, looked at how best to determine which children are at elevated risk for self-harm. Researchers identified four separate profiles to help medical professionals better assess children at elevated ...

The way our senses adjust while playing high-intensity virtual reality games plays a critical role in understanding why some people experience severe cybersickness and others don’t. Cybersickness is a form of motion sickness that occurs from exposure to immersive VR and augmented reality applications. A new study, led by researchers at the University of Waterloo, found that the subjective visual vertical – a measure of how individuals perceive the orientation of vertical lines – shifted considerably after participants played a high-intensity ...

In the race to make the world more livable for people and nature, progress on land outpaced successes in the seas, raising red flags that wealthier countries’ advantages may be upsetting a balance, a Michigan State University study shows. Progress in oceans actually slowed after the United Nations member states adopted the 17 Sustainable Development Goals in 2015. That action aims to facilitate global partnerships among developed and developing countries in sustainable development. So far, though, a new study in the open-access journal iScience reveals evidence that ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have developed a way of mapping the distribution of carnitine in skeletal muscle cells. Carnitine is a small compound that helps transport fatty acids and reduce metabolic byproducts. They discovered that slow-type muscle fibers contained the most, and that activity promptly led to rises in acetylcarnitine, a product of the immediate response of carnitine contained in the cell. Their technique promises new insights into how muscle cells work. Our muscles require ...

The human body relies heavily on electrical charges. Lightning-like pulses of energy fly through the brain and nerves and most biological processes depend on electrical ions traveling across the membranes of each cell in our body. These electrical signals are possible, in part, because of an imbalance in electrical charges that exists on either side of a cellular membrane. Until recently, researchers believed the membrane was an essential component to creating this imbalance. But that thought was turned on its head when researchers at Stanford University discovered that similar imbalanced electrical ...

Astronomers from McGill University are part of an international team that has discovered 25 new sources of repeating fast radio bursts (FRBs), these explosions in the sky that come from far beyond the Milky Way. This discovery brings the total number of confirmed FRB sources to 50. Based on data gathered by the CHIME/FRB collaboration, the new study, published this week in The Astrophysical Journal, may also bring scientists closer to understanding the origins of these mysterious phenomena. A new way of identifying FRBs Thanks to the radio telescopes such as those at CHIME, which scan the entire northern sky every day, the number of detected FRBs has grown exponentially in recent years. ...

The colonization and expansion of plants on land represent a defining landmark for the path of life on Earth. Terrestrial colonization has been attributed to a series of major innovations in plant body plans, anatomy, and biochemistry that transformed global biogeochemical cycles and climates. It is crucial to identify the onset and track the expansion of those earliest land plants. However, the precise timing of land colonization by vascular plants remains controversial due to the sparseness of early land plant megafossils, poor stratigraphic controls ...

Researchers have figured out a way to predict bacteria’s environmental pH preferences from a quick look at their genomes, using machine learning.

CAMBRIDGE, MA — Emerging AI applications, like chatbots that generate natural human language, demand denser, more powerful computer chips. But semiconductor chips are traditionally made with bulk materials, which are boxy 3D structures, so stacking multiple layers of transistors to create denser integrations is very difficult. However, semiconductor transistors made from ultrathin 2D materials, each only about three atoms in thickness, could be stacked up to create more powerful chips. To this end, MIT researchers have now demonstrated a novel technology that can effectively ...

The green hydrogen economy is a sustainable alternative to fossil fuels. However, one of the challenges of constructing a global hydrogen economy is hydrogen transportation by sea. A new paper proposes solid air as a medium for recycling cold energy across the hydrogen liquefaction supply chain. The world is undergoing an energy transition to reduce CO2 emissions and mitigate climate change. The COVID-19 pandemic and the Russia-Ukraine war have further increased the interest of Europe and Western countries to invest in the hydrogen economy as an alternative to fossil fuels. Hydrogen can significantly reduce geopolitical risks ...
