Scientists can tell where a mouse is looking and located based on its neural activity
2024-02-22
Researchers have paired a deep learning model with experimental data to “decode” mouse neural activity. Using the method, they can accurately determine where a mouse is located within an open environment and which direction it is facing just by looking at its neural firing patterns. Being able to decode neural activity could provide insight into the function and behavior of individual neurons or even entire brain regions. These findings, publishing February 22 in Biophysical Journal, could also inform the design of intelligent machines that currently ...
Artificial intelligence matches or outperforms human specialists in retina and glaucoma management, Mount Sinai study finds
2024-02-22
A large language model (LLM) artificial intelligence (AI) system can match, or in some cases outperform, human ophthalmologists in the diagnosis and treatment of patients with glaucoma and retina disease, according to research from New York Eye and Ear Infirmary of Mount Sinai (NYEE).
The provocative study, published February 22, in JAMA Ophthalmology, suggests that advanced AI tools, which are trained on vast amounts of data, text, and images, could play an important role in providing decision-making support to ophthalmologists in the diagnosis and management of cases involving glaucoma and retina ...
A third of trans masculine individuals on testosterone ovulate
2024-02-22
"Trans masculine people are people born female but do not identify as such, for example they feel male, gender fluid or non-binary. Our examination of their ovarian tissue shows that 33% of them show signs of recent ovulation, despite being on testosterone and no longer menstruating," says Joyce Asseler, PhD candidate at Amsterdam UMC.
Trans masculine people often use hormone treatment with testosterone to masculinize physically. This hormone usually stops them from menstruating. In that ...
Researchers use deep brain stimulation to map therapeutic targets for four brain disorders
2024-02-22
A new study led by investigators from Mass General Brigham demonstrated the use of deep brain stimulation (DBS) to map a ‘human dysfunctome’ — a collection of dysfunctional brain circuits associated with different disorders. The team identified optimal networks to target in the frontal cortex that could be used for treating Parkinson’s disease, dystonia, obsessive compulsive disorder (OCD) and Tourette's syndrome. Their results are published in Nature Neuroscience.
“We were able to use brain stimulation to precisely identify and target circuits for the optimal treatment of four different ...

Chronic stress spreads cancer … here’s how
2024-02-22
Stress is inevitable. But too much of it can be terrible for our health. Chronic stress can increase our risk for heart disease and strokes. It may also help cancer spread. How this works has remained a mystery—a challenge for cancer care.
Xue-Yan He, a former postdoc in Cold Spring Harbor Laboratory (CSHL) Adjunct Professor Mikala Egeblad’s lab, says, “Stress is something we cannot really avoid in cancer patients. You can imagine if you are diagnosed, you cannot stop thinking about the disease or insurance ...
Markey study reveals extent of undiagnosed cancer cases due to COVID-19 pandemic
2024-02-22
Over 134,000 cancer cases went undiagnosed in the U.S. during the first 10 months of the COVID-19 pandemic, according to a new University of Kentucky Markey Cancer Center study.
The report published in JAMA Oncology Feb. 22 provides the first estimates of missed cancer diagnoses in 2020 using nationwide surveillance data.

NextGen Precision Health researchers uncover potential treatment for cardiovascular complications from type 2 diabetes
2024-02-22
New research at the Roy Blunt NextGen Precision Health building has discovered a potential treatment for an underlying cause of cardiovascular disease in people with Type 2 diabetes.
More than 30 million Americans live with Type 2 diabetes. One common feature of diabetes is the hardening and inflexibility of blood vessels caused by damage to the endothelial cells in the vascular system. Over time, this can lead to the development and progression of cardiovascular disease, which is the number one cause of death in diabetics. Because endothelial dysfunction is causally linked to cardiovascular disease, there is a considerable ...
Immune cell receptor provides promising immunotherapy target

UTSA doctoral student studies solutions to prevent contaminated water sources
2024-02-22
From Bangladesh to India to Texas, Tom Varner is leveraging his research to improve sources for drinking water around the world.
Varner, a UTSA doctoral student in environmental science and engineering, explored the mobility of arsenic from the sediments surrounding the Meghna River in Bangladesh as part of a National Science Foundation-funded project.
The river flows through central Bangladesh, where elevated concentrations of arsenic in the groundwater threaten the welfare of millions of people. Long-term exposure to arsenic, which is toxic when ingested, can lead ...
Treating newly-diagnosed Crohn’s patients with advanced therapy leads to dramatic improvements in outcomes
2024-02-22
A large-scale clinical trial of treatment strategies for Crohn’s disease has shown that offering early advanced therapy to all patients straight after diagnosis can drastically improve outcomes, including by reducing the number of people requiring urgent abdominal surgery for treatment of their disease by ten-fold.
The PROFILE trial, led by researchers at the University of Cambridge, involved 386 patients with newly-diagnosed active Crohn’s disease. Recruiting from 40 hospitals across the UK, and supported by the National Institute for Health and Care Research (NIHR) Clinical Research Network, it sought to test whether a biomarker – a genetic signature ...
Uncovering anxiety: Scientists identify causative pathway and potential cures
2024-02-22
Anxiety-related disorders can have a profound impact on the mental health and quality of life of affected individuals. Understanding the neural circuits and molecular mechanisms that trigger anxiety can aid in the development of effective targeted pharmacological treatments. Delta opioid receptors (DOP), which localize in the regions of the brain associated with emotional regulation, play a key role in the development of anxiety. Several studies have demonstrated the therapeutic effects of DOP agonists (synthetic compounds which selectively bind to DOPs and mimic the effect of ...
Stronger storms free more nutrients from mud flats
2024-02-22
If storms become stronger in the future due to climate change, more nitrogen may be released from the bottom of coastal seas. This is shown by research of marine biogeochemist Dunia Rios-Yunes at NIOZ in Yerseke. Rios-Yunes will defend her PhD-thesis today at the University of Utrecht. “The dynamics of nutrients in deltas and estuaries have been a bit of a blind spot for marine science, so far”, she says.
Inflatable couch
For her experiments, Rios-Yunes spent many hours on an inflatable couch on ...

Air pollution hides increases in rainfall
2024-02-22
We know that greenhouse gas emissions like carbon dioxide should increase rainfall. The emissions heat the atmosphere, causing a one-two punch: warmer oceans make it easier for water to evaporate, and warmer air can hold more water vapor, meaning more moisture is available to fall as rain. But for much of the 20th century, that increase in precipitation didn’t clearly show up in the data.
A new study led by researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley ...
