  • Treating liver cancer with microrobots piloted by a magnetic field

    Canadian researchers led by Montreal radiologist Gilles Soulez have developed a novel approach to treat liver tumours using magnet-guided microrobots in an MRI device.

    The idea of injecting microscopic robots into the bloodstream to heal the human body is not new. It’s also not science fiction.

  • Virginia Tech researchers discover that blocking an essential nutrient inhibits malaria parasite growth

    Living organisms often create what is needed for life from scratch. For humans, this process means the creation of most essential compounds needed to survive. But not every living thing has this capability, such as the parasite that causes malaria, which affected an estimated 249 million people in 2022.

    Virginia Tech researchers in the College of Agriculture and Life Sciences found that by preventing the malaria parasite from scavenging fatty acids, a type of required nutrient, it could no longer grow.

  • 1 in 9 adults in the United States continue to experience Long COVID

    Four years after the COVID-19 pandemic began, Long COVID remains an unsolved, complex and urgent healthcare crisis. According to the Centers for Disease Control and Prevention, 1 in 9 adults in the United States who have ever had COVID-19 continue to experience Long COVID with a wide range of symptoms. Many symptoms are debilitating, affecting patients’ ability to work and go to school.

  • Study shows ORS remains under prescribed in India

    Health care providers in developing countries know that oral rehydration salts (ORS) are a lifesaving and inexpensive treatment for diarrheal disease, a leading cause of death for children worldwide, yet few prescribe it.

  • Immune genes are altered in Alzheimer’s patients’ blood

    A new Northwestern Medicine study has found the immune system in the blood of Alzheimer’s patients is epigenetically altered. That means the patients’ behavior or environment has caused changes that affect the way their genes work.

    Many of these altered immune genes are the same ones that increase an individual’s risk for Alzheimer’s. Northwestern scientists theorize the cause could be a previous viral infection, environmental pollutants or other lifestyle factor and behaviors.

  • AI model as diabetes early warning system when driving

    Low blood sugar levels (hypoglycemia) are one of the most dangerous complications of diabetes and pose high risk during cognitively demanding tasks requiring complex motor skills, such as driving a car. The utility of current tools to detect hypoglycemia is limited by diagnostic delay, invasiveness, low availability, and high costs. A recent study published in the journal NEJM AI provides a novel way to detect hypoglycemia during driving.

  • Scientists develop a low-cost device to make cell therapy safer

    A tiny device built by scientists at MIT and the Singapore-MIT Alliance for Research and Technology could be used to improve the safety and effectiveness of cell therapy treatments for patients suffering from spinal cord injuries.

  • Lighting up Alzheimer’s-related proteins to allow for earlier disease detection

    Many neurodegenerative diseases, including Alzheimer’s and Parkinson’s, are difficult to diagnose before symptoms begin to appear. However, disease-related biomarkers such as aggregated proteins called amyloids could provide important insight much earlier, if they can be readily detected. Researchers publishing in ACS Sensors have developed one such method using an array of sensor molecules that can light up amyloids. The tool could help monitor disease progression or distinguish between different amyloid-related conditions.

  • Disrupted cellular function behind type 2 diabetes in obesity

    Disrupted function of “cleaning cells” in the body may help to explain why some people with obesity develop type 2 diabetes, while others do not. A study from the University of Gothenburg describes this newly discovered mechanism.

  • Precursor of Cholesterol Protects Cells From Ferroptosis

    In a groundbreaking study, a team led by Würzburg Professor José Pedro Friedmann Angeli has shown that the cholesterol precursor 7-dehydrocholesterol (7-DHC) plays a crucial role as an antioxidant: it integrates into the cell membranes and protects the cells by preventing a certain type of cell death, known as ferroptosis.
