Keratoconus is a progressive eye disease that weakens and thins the cornea, the transparent front surface of the eye. In the early, asymptomatic stage, the cornea may still appear normal on routine examinations. However, at this time, especially when a patient is being evaluated for refractive surgery, an accurate diagnosis is paramount. A recent study found that combining polarization-sensitive optical coherence tomography (PS-OCT) with artificial intelligence reveals subtle corneal changes that are often missed by standard image processing. Published in Discovery of biophotonicsthis study is based on a large clinical dataset and points to new methods to improve early detection…

White Americans who regularly get their political news from Fox News have much higher levels of support for the Great Replacement Theory than those who don’t watch Fox News. By tracking individual viewers over time, researchers found that increases in viewership of certain television shows on this network coincided with increased belief in this conspiracy theory. These findings were published in the journal PS: Political Science & Politics. The Great Replacement Theory is a xenophobic framework with origins in French right-wing political thought. The paper proposes that powerful elites are intentionally relaxing immigration policies to flood the United States with…

Artificial intelligence (AI) is increasingly being considered as a tool to support clinical decision-making, but its actual performance in pediatric diagnosis remains unclear. Pediatric research studies using authentic clinical cases now report that advanced AI models outperform clinicians in diagnostic accuracy, especially for rare diseases, with combined human-AI approaches having the highest overall success. The findings highlight the potential of AI as a complementary tool to improve diagnostic accuracy and patient outcomes. Accurate diagnosis in pediatric medicine can be particularly challenging, especially when rare diseases present with subtle or overlapping symptoms. Early uncertainty in diagnosis can delay treatment and increase…

Researchers at the Johns Hopkins University School of Medicine, in a study supported by the National Institutes of Health’s National Institute on Drug Abuse, added to the evidence that the combination of edible marijuana and alcohol worsens impaired driving compared to either substance taken alone. The study also found that cannabis (alone or with alcohol) did not impair performance on standard field sobriety tests. These findings were announced on May 1st. JAMA Networkhighlights the urgent need for widespread public education about the potential potentiating effects of the combination of cannabis and alcohol and improved roadside driver impairment detection methods. The…

Alzheimer’s disease (AD) is a progressive brain disorder and is the leading cause of dementia worldwide. Despite years of research, there is still no cure. New antibody-based treatments targeting amyloid-β (Aβ) have recently emerged, but their efficacy is modest. These treatments are expensive and can cause immune-related side effects, highlighting the urgent need for safer and more affordable options that can slow disease progression. Recent research published in neurochemistry international It offers amazing possibilities. Researchers at Kindai University and affiliated institutions have discovered that the natural amino acid arginine can reduce the accumulation of harmful Aβ protein in animal models…

The U.S. Supreme Court has temporarily restored online access to the abortion drug mifepristone. The ruling comes in response to an emergency request from manufacturers Danko and GenBioPro to overturn Friday’s ruling by a federal appeals court in New Orleans that banned mifepristone from being prescribed over the phone and sent by mail in the United States. The Supreme Court’s action is an “administrative stay,” giving the court time to consider the request before making a decision. This measure will remain in effect until May 11th and will not disrupt treatment for patients with scheduled appointments. Separate requests from mifepristone…

Being physically healthy can have lifelong benefits that protect your brain and mind. Recent research published in natural mental health It has been suggested that higher levels of cardiovascular fitness are associated with a lower risk of developing conditions such as depression and dementia. These findings provide evidence that keeping the heart and lungs in good shape may be an important part of maintaining long-term mental health. Scientists conducted this study to address gaps in our understanding of how physical health affects the brain. Cardiorespiratory fitness measures how well your body absorbs and utilizes oxygen during sustained physical activity. Previous…

Health experts and others have criticized the Ford government’s approval of a major expansion of a waste incinerator in Brampton as an attack on a region already suffocated by over-the-top pollution.The state government gave the green light for the expansion last year. Emerald Energy from Waste Facilitylocated 40 kilometers west of Toronto, will increase its incineration capacity by almost five times, reaching 900,000 tonnes of trash per year. Once the expansion is complete, the facility will be one of the largest incinerators in North America, burning waste from throughout the Greater Toronto Area and potentially beyond. Final technical approval is…

WASHINGTON – The Supreme Court on Monday restored widespread access to the abortion drug mifepristone, blocking a ruling that threatened to upend one of the primary ways abortions are provided across the country. The order signed by Justice Samuel Alito temporarily allows women seeking abortions to obtain the pills at pharmacies or by mail without visiting a doctor in person. Those rules had been in effect for several years until a federal appeals court imposed new restrictions last week. The majority of abortions in the United States are performed with medication, usually a combination of mifepristone and a second drug,…

After NASA’s Artemis II mission ended with a successful splashdown, engineers began to closely review data from the entire mission. Their goal is to assess how key systems performed, including the Orion spacecraft, the SLS (Space Launch System) rocket, and the ground infrastructure at Kennedy Space Center in Florida. Early findings suggest the test flight accomplished its purpose and helped open the door for future missions, including Artemis III, long-term lunar exploration, and eventually a manned mission to Mars. After orbiting the moon for 694,481 miles, Orion re-entered Earth’s atmosphere on April 10, landing in the Pacific Ocean off the…
