The Smart 3D Printing Research Team at KERI, led by Dr. Seol Seung-kwon has developed the world’s first technology for printing high-resolution 3D microstructures using MXene, a material known as the dream material.
The work is published in the journal Small.
MXene, first discovered in the United States in 2011, is a two-dimensional nanomaterial composed of alternating metal and carbon layers. MXene possesses high electrical conductivity and electromagnetic shielding capabilities.
Scientists in Japan have demonstrated a new method to create hydrogen fuel without emitting greenhouse gases. But key steps to improve its efficiency remain for it to be commercially viable.
The first steps in diagnosis typically involve a physical exam and questions about your medical history.
To help rule out other possible conditions, your healthcare provider may ask about your alcohol use, medications, lifestyle habits, and symptoms. MASH doesn’t always cause symptoms in its early stages, but common signs can include fatigue, abdominal pain, loss of appetite, unintended weight loss, bloating, and thirst.
The agricultural sector in South Africa is undergoing a transformation with the introduction of AI-powered harvesting robots. These advanced machines are set to revolutionize farming by increasing efficiency, reducing labor costs, and ensuring better crop yields. With the growing challenges of climate change, labor shortages, and the need for sustainable farming, AI-driven technology is emerging as a critical solution for modern agriculture.
Artificial intelligence has become a vital tool in various industries, and agriculture is no exception. AI-powered robots are designed to perform labor-intensive tasks such as planting, watering, monitoring crop health, and harvesting. These machines utilize machine learning, computer vision, and sensor technology to identify ripe crops, pick them with precision, and minimize waste.
In South Africa, where agricultural labor shortages and rising costs have posed challenges to farmers, AI-driven automation is proving to be a game-changer. With an estimated 8.5% of the country’s workforce employed in agriculture, technological advancements can significantly improve productivity while alleviating labor constraints.
While the number of smokers in the world as a proportion of the population is dropping, lung cancer continues to cause almost 2 million deaths per year – and new research reports on a concerning rise in cases among people who’ve never lit up a cigarette.
The international team behind the research found that rates of lung cancer in this group of people could be tied to increasing levels of pollution and the subsequent damage to health, with east Asia, particularly China, the worst affected.
“As lung cancer is the leading cancer worldwide, a comprehensive understanding of the changing epidemiological patterns and their potential causes is essential,” write the researchers in their published paper.
Around 15 percent of the world’s population suffers from tinnitus, a condition which causes someone to hear a sound (such as ringing or buzzing) without any external source. It’s often associated with hearing loss.
Not only can the condition be annoying for sufferers, it can also have a serious effect on mental health, often causing stress or depression. This is especially the case for patients suffering from tinnitus over months or years.
There’s currently no cure for tinnitus. So finding a way to better manage or treat it could help many millions of people worldwide.
Our ability to cooperate with others may be influenced by how our attention is captured and directed, as much as by how altruistic we are feeling.
According to a new study by researchers at the University of Birmingham jointly with the University of Zurich, choices made for individual reward or cooperatively for a joint reward can be influenced by presenting information to participants in configurations that naturally draw their attention. The results are published in Communications Psychology.
Cooperation—defined as the ability of individuals to incur a personal cost for the benefit of a group—is a fundamental aspect of human behavior. Understanding how we can foster cooperation is essential for tackling many global challenges, from climate change to the spread of infectious diseases—and understanding what motivates people to cooperate is key to this process.
End-of-life home health use and duration were lower in Medicare Advantage vs traditional Medicare for nearly all populations.
Medicare-funded home health provides critical support through nursing, social work, rehabilitation, and aide visits for homebound adults needing skilled care. This support is particularly relevant for Hispanic and non-Hispanic Black older adults who access hospice services at lower rates than White adults.1,2
Enrollees in Medicare Advantage (MA), who are disproportionately from racially or ethnically minoritized communities, are less likely to receive home health and use fewer days of services compared with those in traditional Medicare ™.3,4 This study assessed whether MA enrollment was associated with greater racial and ethnic disparities in home health use during the last year of life compared with TM enrollment.
Summary: New research reveals that our brains simplify complex social interactions by using basic mental “building blocks” or shortcuts. Researchers scanned the brains of people playing a simple team game and observed how participants kept track of interactions with both teammates and opponents.
Rather than monitoring each individual separately, the brain creates simplified patterns that capture the essential dynamics of group behavior, particularly in the prefrontal cortex—an area important for decision-making and social skills. These findings help explain how we efficiently manage and interpret the constant flood of social information encountered daily.
