NASHVILLE — The six-month follow-up results from the pioneering trial of robotic-assisted neuroendovascular aneurysm embolization using the CorPath GRX system were presented today by Vitor Pereira, MD on behalf of the investigators at the Society of NeuroInterventional Surgery’s (SNIS) 22nd Annual Meeting.
The adjudicated six-month results from the prospective, single-arm, international, multicenter, non-inferiority study demonstrated safety and effectiveness of robotic-assisted neuroendovascular aneurysm embolization. These results represent a significant milestone, as they constitute the only published mid-term clinical follow-up data to date on robotic-assisted neuroendovascular aneurysm embolization.
The study enrolled 117 patients across 10 clinical sites and was conducted by 14 neurointerventionalists spanning six countries. It included both a premarket study in Canada and post-market studies in Australia, Austria, France, Spain and Switzerland.
Key findings of the study include:
A 94% technical success rate, achieving the primary effectiveness endpoint defined as successful completion of the robotic-assisted neuroendovascular procedure without unplanned conversions to manual intervention.
Immediate complete occlusion (RROC 1) of 64.5% increased to 94.1% at six months.
Favorable clinical outcomes (modified Rankin Scale score 0–2) were observed in 98.9% (87/88) of patients at six months.
“The six-month results of the CorPath GRX trial represent a significant step forward in the evolution of neuroendovascular robotics and will play a key role in shaping future innovation in the field of neuroendovascular therapy. I am excited to share this news with the community,” said Dr. Pereira. “It shows that robotics in neuroendovascular interventions could provide precision and support to the physician even in navigating tortuous anatomy and treatment of complex aneurysm cases.”
The neuroendovascular robotic-assisted CorPath GRX trial was sponsored by Siemens Healthineers Endovascular Robotics, Inc. Siemens Healthineers continues to invest in the development of their next-generation neurendoovascular robotic platform.

Elephants that live near farms are more daring than their deep-forest counterparts, and that behavior could be the key to helping people and elephants get along.
That’s the central finding of new research by CUNY Graduate Center alumna Sarah Jacobson (Ph.D. ’24, Psychology), published in Royal Society Open Science. Working with Professor Joshua Plotnik (GC/Hunter, Psychology), Jacobson found that wild elephants on the edge of agricultural land in Thailand were more curious and exploratory when presented with unfamiliar objects than elephants living in protected forests.
The paper is a chapter of Jacobson’s dissertation, completed under Plotnik’s mentorship. ...

Autosomal dominant optic atrophy (ADOA), the most common genetic optic neuropathy, is an insidious disease. It often presents slowly during childhood by way of blurry vision, trouble reading or focusing, and sometimes only as a failed vision test. But behind these subtle signs lies progressive, irreversible vision loss in both eyes caused by deterioration of retinal ganglion cells (RGCs) — the neurons responsible for carrying information from the eyes to the brain. In most cases, the damage is linked to mutations ...

MISSION VIEJO, Calif. (July 16, 2025) – Findings from a newly published randomized controlled trial offer surprising insights for the one in three adults at greater risk of heart disease because of prediabetes. The study explored how snacking on avocado at night affects health markers the next morning, in line with the “second-meal effect” – the idea that the composition of a previous meal can affect how the body processes the next meal.
The results suggest snacking on avocado at night may promote healthier triglyceride metabolism the next morning. Triglycerides are the most common type of fat in the body, but elevated levels can be a sign of insulin resistance, ...

HOUSTON – July 16, 2025 – Chemotherapy used to target and kill bladder cancer cells may trigger an inflammatory response that ultimately may make the cancer more resistant to treatment, according to new research from scientists at Houston Methodist.
The findings are highlighted in “Caspase-1–dependent pyroptosis converts αSMA+CAFs into collagen-III high iCAFs to fuel chemoresistantcancer stem cells,” which was recently published in Science Advances. The researchers examined why ...

Birds have developed a unique evolutionary solution to ensure the survival of males – a powerful microRNA. This tiny gene allows male embryos to survive despite a genetic imbalance between the sexes by balancing the activity of the sex chromosomes. An international research team led by biologists from Heidelberg University and the University of Edinburgh (Scotland) has discovered this previously unknown mechanism, which differs significantly from the system that mammals have developed in the course of evolution ...

Research led by Memorial Sloan Kettering Cancer Center (MSK) is shedding new light on how ovarian cancer evolves — insights that could help researchers develop more effective treatment strategies.
While ovarian cancer diagnoses and deaths have decreased over recent decades, the disease remains a leading cause of cancer-related death in women. This is largely because the cancer often spreads at a microscopic level within the abdomen early on, resulting in diagnosis at an advanced stage when treatment is less effective.
A ...

What if neighbourhoods could lower their electricity bills without investing in expensive battery systems? An international study led by researchers at CWI (the national research institute for mathematics and computer science in the Netherlands) suggests exactly that: by leasing capacity from large, commercially operated batteries, communities can access the benefits of energy storage without the high upfront costs or additional technical challenges.
In collaboration with GIGA Storage, a leading operator of grid-connected batteries in the Netherlands, the University of Glasgow (UK) and ...

WASHINGTON, D.C., (July 16, 2025) – Researchers now have a powerful new way to understand the types of brain cells that are affected in neurodegenerative diseases and to uncover connections between conditions such as Parkinson’s, Alzheimer’s, and other forms of dementia.
The Aligning Science Across Parkinson’s (ASAP) initiative and Allen Institute are joining forces to unlock insights into Parkinson’s and other neurodegenerative diseases through an expansion of the Allen Brain Cell (ABC) Atlas visualization tool – uniting data from millions of human brain cells and enabling researchers to explore the brain ...

NEW YORK, NY (July 16, 2025)--With the help of artificial intelligence (AI), an inexpensive test found in many doctors’ offices may soon be used to screen for hidden heart disease.
Structural heart disease, including valve disease, congenital heart disease, and other issues that impair heart function, affects millions of people worldwide. Yet in the absence of a routine, affordable screening test, many structural heart problems go undetected until significant function has been lost.
“We have colonoscopies, we have mammograms, but we have ...

Just like any living organism, the soil has its own metabolism. Plants, worms, insects, and most importantly, microorganisms in the soil, break down organic matter, consume and generate nutrients, and process other materials to give the soil a life of its own. Soil microbiomes, which drive much of the metabolism in these ecosystems, are immensely complex – comprised of thousands of species with untold interactions and dynamics.
Given the complexity of the soil, however, it can be nearly impossible to understand how the communities of microbes living there respond to changes in the environment, such as temperature, moisture, acidity, and nutrient availability. Solving this problem is ...
