Choosing paint for your home brings a lot of options: What kind of paint, what type of finish and what color? Water-based paints have emerged as “greener” and less smelly than solvent-based options. And they are often advertised as containing little-to-no volatile organic compounds (VOCs).
To better understand COVID-19’s spread during the pandemic, public health officials expanded wastewater surveillance. These efforts track SARS-CoV-2 levels and health risks among most people, but they miss people who live without shelter, a population particularly vulnerable to severe infection.
A new multicenter, international study suggests that people who have early-stage triple-negative breast cancer (TNBC) and high levels of immune cells within their tumors may have a lower risk of recurrence and better survival rates even when not treated with chemotherapy.
Polymer-based hydrogels are used to treat skin ailments and in tissue engineering because of their ability to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture and not very resilient to external forces like rubbing against clothing, sheets, or wound dressings.
Owning a home has long been considered a crucial way to build wealth, but making such a purchase has become increasingly difficult for many residents. In addition to steep housing prices and high interest rates, there have been a growing number of all-cash buyers who can close a deal quickly, beating out competing offers from buyers who need to finance their home with a mortgage.
Moffitt Cancer Center announced today a collaboration with NVIDIA, Oracle and Deloitte* on an initiative aimed at revolutionizing cancer care delivery through advanced artificial intelligence and machine learning technologies.
A new study found that during the pandemic pediatric emergency departments (EDs) saw more children and adolescents who needed a psychiatric admission, as well as an increase in severe conditions, such as bipolar disorder, schizophrenia and substance use disorders.
Mental health issues during pregnancy or the first year of parenthood have a much greater chance of getting detected and treated now than just over a decade ago, a trio of new studies suggests. But the rise in diagnosis and care hasn’t happened equally across different groups and states.
Using cutting-edge computational methods and supercomputing infrastructure at UC San Diego, researchers have built the largest and most detailed bird family tree to date—an intricate chart delineating 93 million years of evolutionary relationships between 363 bird species, representing 92% of all bird families.
A pair of research papers reveals that genomic anomalies misled scientists about the true evolutionary history of birds.
ChatGPT-4, an artificial intelligence program designed to understand and generate human-like text, outperformed internal medicine residents and attending physicians at two academic medical centers at processing medical data and demonstrating clinical reasoning. In a research letter published in JAMA Internal Medicine, physician-scientists at Beth Israel Deaconess Medical Center (BIDMC) compared a large language model’s (LLM) reasoning abilities directly against human performance using standards developed to assess physicians.
An initiative at Bon Secours Mercy Health Anderson hospital in Cincinnati demonstrates the potential impact of integrating a simple screening tool at the point of admission to trigger automatic referrals for palliative care consultations for critically ill patients.

• Sedentary time decreased, stepping time increased, and number of steps per day increased among patients with chronic kidney disease assigned to the ‘Sit Less, Interact, Move More’ intervention. • These effects were not sustained after 20 weeks, however.
When and how mothers drink alcohol during pregnancy has major implications for fetal and child development, according to two new studies in Alcohol: Clinical & Experimental Research. The effects of prenatal alcohol exposure (PAE) include stillbirth, preterm delivery, and fetal alcohol spectrum disorder (FASD).
DNA replication—which happens when cells divide—is one of the most important processes in all living organisms. In a landmark finding, published today in Cell, scientists identified a multi-protein “machine” in cells that helps govern the pausing or stopping of DNA replication to ensure its smooth progress.
People who are able to adapt their self-regulation skills depending on the context are more likely to be successful in quitting harmful drinking.
UC San Diego biologists have uncovered a quality control timing mechanism tied to cell division. The “stopwatch” function keeps track of mitosis and acts as a protective measure when the process takes too long, preventing the formation of cancerous cells.
SARS-CoV-2 will eventually become resistant to the only effective oral treatment. The world needs another.
In a survey of more than 200 U.S. oncologists, vast majority indicate that oncologists should be able to explain how AI works to their patients. Respondents say AI developers, more than oncologists or hospitals, have responsibility for legal issues arising from AI use in cancer care.
People with symptoms of insomnia may be likely to increase their drinking over time, according to a study published in Alcohol: Clinical and Experimental Research. In the study of adult drinkers, people who had worse insomnia symptoms at the outset of the study tended to increase the amount they drank and the number of times they binge drank during the subsequent year. The researchers found that, even at subclinical levels, insomnia symptoms were a significant predictor of future drinking in adults, suggesting that insomnia symptoms should be addressed to help reduce the risk of problem drinking.
Experts advance models for speedy adoption for better diagnosis and therapy in The Lancet.
Artificial intelligence (AI) may serve as a future tool for neurologists to help locate where in the brain a stroke occurred. In a new study, AI processed text from health histories and neurologic examinations to locate lesions in the brain. The study, which looked specifically at the large language model called generative pre-trained transformer 4 (GPT-4), is published in the March 27, 2024, online issue of Neurology® Clinical Practice, an official journal of the American Academy of Neurology.
A pair of medications that make malignant cells act as if they have a virus could hold new promise for treating colorectal cancers and other solid tumors, reports a study published today in Science Advances.
Just as you can’t make an omelet without breaking eggs, scientists at Albert Einstein College of Medicine have found that you can’t make long-term memories without DNA damage and brain inflammation. Their surprising findings were published online today in the journal Nature.
Persons with a higher genetic risk of obesity need to work out harder than those of moderate or low genetic risk to avoid becoming obese, according to a Vanderbilt University Medical Center (VUMC) paper published in JAMA Network Open.
Medical imaging has previously been identified as a potential driver of U.S. healthcare spending growth. A study by the Harvey L. Neiman Health Policy Institute evaluated the degree to which imaging has contributed to aggregate medical cost growth.
New research by the University of Bristol Veterinary School has found the majority of rabbit owners could list signs of pain and could mostly identify pain-free rabbits and those in severe pain, but many lacked knowledge of the subtler sign of pain.
Researchers have used advanced sequencing technology to determine how the mix of microbes present in patients with healthy eyes differs from the mix found in patients with dry eye.
Researchers at the Keck School of Medicine, University of Southern California, have discovered that a protein called Piezo1 prevents a type of immune cell in the lung from becoming hyperactivated by allergens.
