A new study has found that molecules that help control gene activity are linked to both the growth of skin cancers and their ability to evade the body’s immune defenses. Scientists at New York University Langone Health and its Perlmutter Cancer Center have discovered that a key protein known as the transcription factor HOXD13 plays a central role in melanoma. This protein is important in the formation of blood vessels that supply oxygen and nutrients to tumors. Transcription factors such as HOXD13 control how genetic instructions in DNA are translated into proteins that build and maintain the body. HOXD13 promotes…
Recent research published in Proceedings of the National Academy of Sciences It suggests that giving high school students unlimited access to artificial intelligence for math practice may impair their ability to learn. AI chatbots can help students solve problems correctly when the technology is available, but when the AI is removed, these students perform worse on independent exams than their peers who did not use the tool at all. Generative artificial intelligence refers to computer programs that can instantly create original content, such as conversational text or mathematical solutions, by analyzing patterns in large amounts of existing data. Although this…
In a continuing push to reform the coal industry, President Donald Trump’s administration recently renewed efforts to ease cleanup requirements for the toxic ash left when coal is burned. Conservation groups say the measures could increase the risk of increased groundwater contamination. But in Virginia, state law strictly regulates how coal ash cleanup is managed at specific sites. Proposed changes to federal regulations Earlier this month, the Environmental Protection Agency proposed changes Regarding the disposal of coal combustion residues (CCR), also known as coal ash, which contain toxic heavy metals such as mercury, lead, and arsenic. The announcement of the…
A team led by Professor Tao Zhang and Professor Yanqiang Huang from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), in collaboration with Professor Wei Liu from DICP and Professor Yanggang Wang from Southern University of Science and Technology, directly tracked the movement of oxygen in the catalyst. They used environmental transmission electron microscopy to observe bulk oxygen efflux in Ru/rutile-TiO2 catalysts for the first time. This discovery suggests a new way to utilize the interior of catalysts, which has often been overlooked until now. The survey results are nature April 15, 2026. What…
Conservationists are calling for restrictions on pet flea control after a study found that songbird feathers are extensively contaminated with a substance that can damage the birds’ brains and kill unborn chicks.Almost all tested feather samples from five common UK garden bird species contained either permethrin, imidacloprid or fipronil. Although both of these insecticides are banned for agricultural use, they are still common in treating ticks and fleas on pets.Fipronil and imidacloprid are known to impede reproductive success and disrupt neurological function in garden birds, while permethrin was found to slow growth rates and suppress feather growth in wild bird…
In outpatient care, decisions are made quickly. The prescription will be sent to the pharmacy. A referral to a specialist will be made. An inspection is ordered. From the patient’s perspective, this process feels instant. Care begins immediately after your visit. But often that’s just the beginning of the story. Days or weeks later, the system starts asking questions about the same decision. I got a call from the pharmacy because the drug requires prior authorization. The insurance company will review the documentation that supports your claim. The referral will trigger a request for additional notes explaining why the service…
Madecassic acid is widely known as a calming “hero ingredient” in Korean skin care, but new research suggests it may play an even bigger role. Scientists at the University of Kent have discovered that this plant-based compound could help fight one of the most pressing global health threats: antibiotic-resistant bacteria. The researchers, in collaboration with colleagues at University College London (UCL), studied madecassic acid using a combination of computer-based screening and laboratory experiments. This natural chemical is Gotukolaa commonly used Asian medicinal herb. Their results show that this compound has strong antibacterial properties and could serve as a starting point…
Southern California may have an unexpected ally in the fight to save honeybees. As commercial hives across the United States struggle to withstand attacks from deadly parasites, a unique hybrid honey bee found in the region is showing remarkable resilience. Beekeepers across the country are reporting that they will lose up to 62% of the bee colonies they manage in 2025, raising serious concerns about food production. These losses are related to several pressures such as exposure to pesticides, climate stress, habitat shrinkage, and habitat loss. One of the most harmful threats is the Varroa mite. Impact of Varroa mites…
A new study reveals a link between extreme weather and cardiovascular disease risk in middle-aged and older adults in 157 cities in China. Depending on the city’s climate and location, exposure to extreme heat, cold, and precipitation each increase the risk of heart disease. The research results in American Journal of Preventive MedicineThis paper, published by Elsevier, provides evidence to help policy makers in different regions develop targeted strategies to protect vulnerable populations during extreme climate change. As climate change accelerates, extreme weather events (ECEs) are intensifying globally, posing an unprecedented threat to public health. China’s population is aging rapidly,…
Between 2020 and 2024, the number of unique US sites where Phase I clinical trials for non-small cell lung cancer (NSCLC) were conducted decreased by 44% and became increasingly concentrated in the top 20 largest clinical trial sites, primarily located in large cities, according to results presented at the American Association for Cancer Research (AACR) Annual Meeting 2026, held April 17-22. The U.S. Food and Drug Administration (FDA) has been working for decades to improve representation in clinical trials, and in the last year, the FDA’s Oncology Drug Advisory Committee (ODAC) held several meetings to address the under-enrollment of U.S.…
