Age-related macular degeneration (AMD) is the most common cause of vision loss among people aged 50 and older, affecting an estimated 7.3 million individuals in the United States. Of these patients, 1.75 million have advanced AMD and will lose vision from this condition. This includes patients with the “wet” form of AMD, characterized by the growth of abnormal blood vessels in the retina that can bleed or leak damaging fluids into the central portion of this light-sensing tissue.
The specs and claims made for this salt water powered EV were incredible in 2015. So what happened to the Quant 48 EV?
Over the past few decades, engineers and material scientists have created increasingly advanced and efficient solar technologies. Some of these technologies are based on photovoltaics with a so-called heterojunction structure, which entails the integration of two materials with distinct optoelectronic properties.
Researchers at Technische Universität Dresden have recently realized a different type of solar cells, referred to as phase heterojunction (PHJ) solar cells. These cells, introduced in a paper published in Nature Energy, were fabricated using two polymorphs (i.e., structural forms) of the same material, the perovskite CsPbI3, instead of two entirely different semiconductors.
“The realization of a PHJ requires the ability to fabricate two different phases of the same perovskite composition on top of each other,” Yana Vaynzof, lead author of the paper, told TechXplore. “While the fabrication of CsPbI3 perovskite by solution-processing is well established in the literature, we needed to develop a method to deposit a perovskite without dissolving the underlying layer, so we decided to use thermal evaporation for this purpose.”
Examinations using microscopes confirmed that these neurons were active in the mice with chronic pain. When the researchers used chemicals to stop the neuronal activity in this cortex, the mice’s appetites improved.
Similarly, when the researchers used chemicals to activate these neurons in mice that weren’t in pain, the animals ate less, even if they had been deprived of food before the experiment.
This is the first time that researchers have traced the brain mechanisms behind pain-related appetite loss, the researchers wrote.
Researchers have just caught bacteria sidestepping antibiotic treatment with a never-before-seen trick.
Bacteria’s troublesome talent for developing resistance against antibiotics is a rapidly growing health threat. This ability has ancient origins and allows drug-resistant bacterial infections like MRSA and gonorrhea to kill 1.3 million people globally each year.
These superbugs are even finding their way into wild animals, such as dolphins and bears.

A new study led by UCL researchers has identified patterns in how common health conditions occur together in the same individuals, using data from 4 million patients in England.
With advancing age, millions of people live with multiple conditions—sometimes referred to as multimorbidity—and the proportion of people affected in this way is expected to rise over the next decades. However, medical education and training, health care delivery, clinical guidelines and research have evolved to focus on one disease at a time.
The Academy of Medical Sciences and the UK Chief Medical Officer (CMO) have recognized this problem and set out a challenge of investigating which diseases co-occur in the same individuals and why.
It’s hard to keep surfaces clean in public spaces, but what if they could be protected with a spray that eliminates illness-causing microorganisms? Now, a new antimicrobial option is in the works.
