Magnetoelectric Material Stimulates Neurons Minimally Invasively
Researchers at Rice University have developed a magnetoelectric material that converts a magnetic field into an electric field. The material can be formulated such that it can be injected into the body, near a neuron, and then an alternating magnetic field can be applied to the area from outside the body. Magnetic fields are very useful in this context, as they can easily penetrate tissue without causing any damage. This magnetoelectric effect produces a small electrical current near the neuron, effectively stimulating it, without the need for invasive implants. So far, the researchers have shown that the technology can br...

Malnutrition Can Impact Wound Healing
Malnutrition can have a significant impact on wound healing. Proper wound healing is a complex process that involves various cellular and biochemical reactions. When the body is malnourished, it lacks the essential nutrients necessary for these processes, which can lead to delayed or impaired wound healing. Here are some key relationships between malnutrition and wound healing:
1. Protein Deficiency: Protein is crucial for tissue repair and the production of collagen, which is essential for wound healing. Malnourishment, especially a lack of adequate protein intake, can lead to a delay in wound closure and reduced tensile ...

Vitamins and Wound Healing
Wound healing is a complex biological process that involves inflammation, tissue formation, and tissue remodeling. Vitamin supplements can play a role in wound healing by supporting various aspects of the body’s natural healing processes. Here are some key vitamins and minerals that are important for wound healing:
Vitamin C: Vitamin C, also known as ascorbic acid, is essential for collagen synthesis, a protein that helps in the formation of skin, blood vessels, and connective tissue. Collagen is a crucial component of wound healing. Adequate vitamin C intake can promote tissue repair and reduce the risk of infectio...

A heartbreaking COVID-19 case: the importance of trust in medical care
An excerpt from One Hundred Prayers: God’s answer to prayer in a COVID ICU. (August 30, 2021) Susan was 44 years old and previously healthy; an ardent anti-masker. When she caught delta COVID, she took ivermectin, zinc and vitamin C. She arrived at our ER about a week later, requiring immediate intubation. Mayfield started her

Microneedle Patch for Antibiotic-Free Acne Treatment
Researchers at the University of Hong Kong have developed a microneedle patch for the drug-free treatment of skin infections, such as acne. Acne is often treated using antibiotics, but these have limited effectiveness over the long term and can result in drug-resistant bacteria. In an effort to develop a drug-free alternative, these researchers have created a microneedle patch that is ultrasound responsive. The patch contains zinc-based nanomaterials that produce a substantial amount of reactive oxygen species when stimulated using ultrasound. These reactive oxygen species are highly effective at killing acne-causing bacte...

Modeling a Cellular Cascade of Alzheimer's Disease
Alzheimer's disease is complex and puzzling, and massively funded, high-profile efforts to find treatments for the condition have been failing for decades. The research community has focused on clearance of amyloid-β, as this protein accumulates and misfolds in Alzheimer's patients. Yet some old individuals exhibit high levels of amyloid-β and do not suffer Alzheimer's, while clearance of extracellular amyloid-β fails to meaningfully improve the condition of patients. It may be that intracellular amyloid-β is the real target, or that amyloid-β accumulation is a side-effect of the real pathological mechanisms.
O...

Nanowire Assay Detects Brain Tumors from Urine
Researchers at Nagoya University in Japan have developed a nanowire assay that can be used to capture and detect specific extracellular vesicles in a urine sample that indicate the presence of a brain tumor. These extracellular vesicles are naturally excreted in the urine but techniques to capture and analyze them have been complex, requiring different pieces of equipment, until now. This all-in-one assay uses a simple well plate that has been coated with zinc oxide nanowires that extracellular vesicles are attracted to because of their surface electrical charge. Then, the researchers can detect tumor-specific extracellula...

High Blood Pressure and Erectile Dysfunction
Research confirms that high blood pressure and ED are closely linked. But did you know the majority of cases of ED are caused by hypertension? Keep reading to find out more.
Experts suggest that “hypertension is sometimes a standalone condition and sometimes it’s associated with other conditions, which also impact erectile dysfunction.”
According to the European Society of Cardiology, this likelihood is almost double in men with uncontrolled high blood pressure.
Long-term exposure to hypertension and elevated blood pressure damages the arterial wall. This leads to atherosclerosis and the narrowing of art...

3D Printed Light Sensor for Light-Sensitive Disease
At the University of Minnesota a team of researchers has developed a 3D printed light sensing wearable that can help people with light-sensitive diseases, such as lupus, to understand more about the types of light that can exacerbate their symptoms. Many people with lupus are sensitive to light, such as sunlight or even regular indoor light, but they may not know what specific light conditions are likely to cause flare-ups. This new device aims to provide such people with more information, so that they can learn more about their flare-ups and take steps to avoid or reduce them. The technology could lead to more personalize...

Surface Coating Rapidly Kills Pathogens, Lasts Months
A team at the University of Michigan has developed a coating for frequently touched surfaces that can rapidly kill a wide array of pathogens, including MRSA and SARS-CoV-2. The technology incorporates polyurethane that contains crosslinked compounds from essential oils with wide-spectrum anti-microbial action. The researchers fine-tuned the crosslinking process so that the oils were available to kill microbes but not sufficiently free to evaporate rapidly. Unlike anti-microbial surface coatings that are based on metals, such as copper or zinc, the new coating can kill microbes quite fast, in as little as two minutes. Howev...

How Common Has Private Currency Been?
Lawrence H. WhiteRecently, an investment advisor and Bitcoin proponenttweeted the claim that “[f]or most of human history” the “[s]eparation of money and state was the norm, even if the state stamped their ruler’s face on the coin.” Some strong disagreement (and some strong support) followed the tweet. The mostcategorical criticism asserted: “Money is and always has been a creation of government. ” A somewhat milder challenge asserted that “Private moneys have seldom been main media of exchange.”First, let ’s clarify the object of the discussion. If we define “money” the way that economist...

Spray Coating Fights Viruses and Bacteria
Researchers at the University of Sydney in Australia engineered a new spray coating for surfaces that provides long-term protection against bacterial and viral contamination. The material is intended as a long-term alternative to disinfectant sprays and combines hydrophobic properties with antimicrobial nanoparticles to reduce microbial contamination.
The hydrophobicity of the coating prevents liquid droplets from spreading over the surface, helping to prevent biofilm formation and microbial colonization. If the coating becomes damaged, reducing its hydrophobic properties, a second line of defense in the form of nanopa...

Artificial Skin Senses Pressure, Temperature, Humidity
Researchers at Graz University in Austria have created an artificial skin that is more sensitive than your fingertip. The skin contains 2,000 sensors per square millimeter, and the researchers designed it to sense humidity, temperature, and pressure, just like human skin. The tiny sensors within the skin material consist of a hydrogel core and a piezoelectric zinc oxide shell. The hydrogel expands or contracts depending on the temperature and also when it absorbs moisture. Pressure can also affect the zinc oxide shell, and these changes lead to an electrical charge, forming the basis of the sensing technology. The material...
