Using pilocarpine eye drops following Kahook Dual Blade (KDB) goniotomy surgery may improve clinical outcomes for patients with glaucoma and reduce the need for future medications, according to new research published by faculty members and trainees in the Department of Ophthalmology at the University of Colorado School of Medicine. “The KDB goniotomy is a minimally invasive glaucoma surgery that we do a lot here at the Sue Anschutz-Rodgers Eye Center, and there was some variability in the post-operative eye drop regimen among different providers,” says Julia Xia, MD, a uveitis ...

Stanford Medicine researchers have developed a blood test capable of detecting cancers, the ways cancer resists treatments and tissue injury caused by non-cancerous conditions. The new test analyzes RNA molecules in the bloodstream. This type of RNA is called cell-free RNA because the tiny molecules no longer inhabit a cell. There are always fragments of both DNA and RNA floating in blood — byproducts of natural cell death from all types of tissues and organs throughout the body, including cancerous tumors. The researchers spent more than six years developing novel methods to target messenger RNA in blood and then used it to identify the presence of cancers at different stages, ...

Primary progressive aphasia is a neurological condition that causes a gradual decline in language abilities. There is no cure or medication that can reverse or stop the progression of PPA. The standard practice in the clinical setting is speech-language therapy to help people with PPA maintain their ability to communicate.  University of Arizona neuroscientists have come up with a new treatment approach for PPA that combines traditional speech therapy with noninvasive electrical stimulation of the brain. The technique – called transcranial direct current stimulation – uses a low electrical current applied through electrodes on the scalp.  A ...

By John Lovett University of Arkansas System Division of Agriculture Arkansas Agricultural Experiment Station FAYETTEVILLE, Ark. — While biodegradable plastics currently account for a half percent of the hundreds of millions of tons of plastic produced annually, a growing demand for the alternative reflects consumer awareness and corporate response. Researchers from Brazil, Germany and the United States document a multi-faceted global snapshot of the environmental aspects and trends surrounding single-use plastics in a review article titled “Rethinking single-use plastics: Innovations, policies, consumer awareness and market ...

Understanding the acceleration of human impacts on the environment is key to addressing the complex planetary and social challenges of the Anthropocene. But even as the inter-relatedness of environmental, political, and social processes becomes clearer, the conditions that produce sustainable outcomes remain little understood.  Now, a new study examines the acceleration of social-ecological changes in the first kingdom in Poland, the Piast dynasty, identifying the factors that contributed to its failure. Using new high-resolution ...

In the largest study of its kind, researchers at the Florida Museum of Natural History have used data from a 120-year-old program managed by the U.S. Department of Agriculture to quantify the effects of introduced species. The researchers included more than 5 million measurements from individual trees across much of eastern North America and showed the rate at which introduced species are spreading has increased over the last two decades. Additionally, native tree diversity is on the decline in areas where exotic species originally introduced by humans have encroached. This ...

The Krebs cycle is a series of chemical reactions that occur in the cells of living beings. It can produce energy from the degradation of certain types of molecules (lipids, sugars, proteins). This energy is then used by the cell to produce the energy essential to cell function. These fine layers of ice form on dust grains in space, and are irradiated by ultraviolet radiation and cosmic rays. Organic molecules that play a role in the chemical processes behind the origins of life. At the Nice Institute of Chemistry (CNRS/Université Côte ...

UNIVERSITY PARK, Pa. — In 2024, more than 50 million people in the United States lived in counties with no air-quality monitoring, according to a new study from researchers in the Penn State College of Health and Human Development. Rural counties — especially counties in the Midwest and South — were less likely to have an air-quality monitoring site. Air quality measures are used to estimate people’s exposure to air pollution, which makes monitoring a critical public health tool, according to Nelson Roque, assistant professor of human development and family studies and ...

COLUMBUS, Ohio – Capitalizing on the flexibility of tiny cells inside the body’s smallest blood vessels may be a powerful spinal cord repair strategy, new research suggests. In mouse experiments, scientists introduced a specific type of recombinant protein to the site of a spinal cord injury where these cells, called pericytes, had flooded the lesion zone. Once exposed to this protein, results showed, pericytes change shape and inhibit the production of some molecules while secreting others, creating “cellular bridges” that support regeneration of axons – the long, slender extensions of nerve cell bodies that transmit messages. Researchers ...

Lucid dreaming is a surreal phenomenon in which people are consciously aware that they are in a dream. Çağatay Demirel, from Donders Center for Cognitive Neuroimaging, Radboud University Medical Center, and colleagues shed light on the neural correlates of lucid dreaming in their JNeurosci paper.   The researchers used a rigorous processing pipeline as they collected and assembled data from multiple labs to create what is, according to the authors, the largest sample size to date for this field of research. Comparisons of brain activity during lucid dreaming, rapid eye movement sleep, and wakefulness revealed distinct activity patterns for ...

One in ten people will have at least one seizure in their life, but effective treatments for seizures remain very limited, in part due to incomplete understanding of the brain mechanisms involved. Now, research in fruit flies has uncovered a role for two specific brain proteins that are necessary during brain development to prevent seizures. The two proteins, Imp and Sdc, are found in the developing brains of both flies and mammals, and are involved in the growth and development of neurons and brain circuits. A reduction of either protein during development makes flies prone to seizures without otherwise affecting their ability to move, the researchers found. ...

Tracing its roots to fundamental research conducted at Princeton, a new startup is upending decades-old approaches for the way the world extracts lithium and other materials, including nitrate and potash, that power today’s clean energy technologies and support modern agriculture. The company, Princeton Critical Minerals (formerly PureLi), which emerged from the University’s ecosystem for innovation and entrepreneurship, has developed a technology for boosting minerals production from evaporation ponds. These ponds currently generate around 40% of the world’s lithium and most of its naturally occurring nitrate. The technology is a black disc with a special, ...

There has been a troubling rise in adolescent mental health struggles and suicide rates over the past decade, with a dramatic increase following the start of the COVID-19 pandemic. This crisis has been accompanied by an increased demand for pediatric inpatient psychiatry units (IPUs) across the United States. However, despite the growing need, which has reached the point of bed shortages, the effectiveness of IPUs on teen mental health outcomes remains understudied. This study, led by Dr. Patricia Ibeziako from Boston Children’s Hospital, reviewed the electronic medical records ...

Newly published results of a randomized, controlled clinical trial in Japan among more than 170 children aged 1 to 6 who underwent surgery, show that by using EEG readings of brain waves to monitor unconsciousness, an anesthesiologist can significantly reduce the amount of the anesthesia administered to safely induce and sustain each patient’s anesthetized state. On average the little patients experienced significant improvements in several post-operative outcomes, including quicker recovery and reduced incidence of delirium. “I think the main takeaway is that in kids, using the EEG, we can reduce the amount of anesthesia we give them and maintain the same level of unconsciousness,” ...

For the first time, wild chimpanzees have been pictured eating and sharing fruit containing alcohol. A research team led by the University of Exeter set up cameras in Guinea-Bissau’s Cantanhez National Park. Footage of chimps sharing fermented African breadfruit – confirmed to contain ethanol (alcohol) – raises fascinating questions about if and why chimps deliberately seek out alcohol. Humans are believed to have consumed alcohol far back into our evolutionary history, with benefits for social bonding. And the new study suggests our closest relatives might be doing something ...
