The cells in your pancreas, like people, can only handle so much stress before they start to break down. Certain stressors, such as inflammation and high blood sugar, contribute to the development of type 2 diabetes by overwhelming these cells. Researchers at The Jackson Laboratory (JAX) have now discovered that DNA sequence changes known to increase a person’s risk for diabetes are linked to how well pancreatic cells can handle two different kinds of molecular stress. In people with these DNA changes, the insulin-producing ...

CHAPEL HILL, North Carolina — A growing reliance on industry-sponsored cancer clinical trials in the United States is a reason for concern, say researchers from the UNC Lineberger Comprehensive Cancer Center. In a Journal of Clinical Oncology editorial, Yara Abdou, MD, and Norman E. Sharpless, MD, responded to a new study by the Fred Hutchinson Cancer Center in Seattle that found enrollment in industry-sponsored cancer clinical trials doubled between 2008 and 2022 while federally supported trial enrollment remained flat. From 2018 to 2022, cancer clinical trial enrollment was eight times greater in industry-sponsored studies compared to federal studies. Abdou and Sharpless called ...

Washington, D.C.  — A new national survey shows that, despite intense marketing, most Americans do not want the new weight-loss injectables, such as Wegovy and Ozempic. The survey was conducted by Morning Consult for the Physicians Committee for Responsible Medicine, a non-profit organization with more than 17,000 physician members, on Sept. 5, 2024, and included 2,205 adults. Asked to respond to the statement, “If I wanted to lose weight, I would rather take an injectable weight-loss drug, rather than make a diet change,” only 23% agreed or strongly agreed, while 62% disagreed or strongly disagreed and another 14% said they were not ...

Two new apps will enable blind people to navigate indoor buildings with spoken directions from a smartphone app, providing a safe method of wayfinding where GPS doesn’t work.  UC Santa Cruz professor of Computer Science and Engineering Roberto Manduchi  has devoted much of his research career to creating accessible technology for the blind and visually impaired. Throughout years of working with these communities, he has learned that there is a particular need for tools to help with indoor navigation of new spaces. “Moving about independently in a place that you don't know is particularly ...

Researchers from IOCB Prague are furthering the understanding of how medicines work and what it takes to develop their most effective variants. In one current study, they have focused on the disease caused by the protozoan parasite Trichomonas vaginalis, especially because of the recent appearance of strains that are resistant to conventional treatment. In an effort to find a new weak spot of this parasite, the research group led by Dr. Evžen Bouřa has succeeded in preparing a key enzyme complex – the proteasome. This has made it possible to gain knowledge that is indispensable for the development of new effective ...

Lewy bodies are a hallmark of Parkinson's disease (PD) and other related neurological conditions. Understanding why and how they develop is critical to developing better treatments. A study from The Neuro (Montreal Neurological Institute-Hospital) of McGill University, in collaboration with its Early Drug Discovery Unit, has recreated the growth of Lewy bodies in human neurons and followed their formation to gain important insight into why and how they form. Critically, they find that immune challenge is important for this process, identifying a previously unknown link between the immune system and neurological disease.    Lewy ...

MIT engineers have built a new desalination system that runs with the rhythms of the sun.  The solar-powered system removes salt from water at a pace that closely follows changes in solar energy. As sunlight increases through the day, the system ramps up its desalting process and automatically adjusts to any sudden variation in sunlight, for example by dialing down in response to a passing cloud or revving up as the skies clear.  Because the system can quickly react to subtle changes in sunlight, it maximizes the utility of solar energy, producing large quantities of clean water despite ...

Generative AI still needs to find the right balance between too little and too much care before it can help doctors make decisions in the Emergency Department.  If ChatGPT were cut loose in the Emergency Department, it might suggest unneeded x-rays and antibiotics for some patients and admit others who didn’t require hospital treatment, a new study from UC San Francisco has found.   The researchers said that, while the model could be prompted in ways that make its responses more accurate, it’s still no match for the clinical judgment of a human doctor.  “This ...

Whilst there is emerging evidence ...

Most dog owners didn’t know that flea and tick treatments are dangerous to aquatic life, suggesting more awareness could ease the problem. A study on Hampstead Heath shows that ponds where dogs are allowed to swim contain levels of two pesticides harmful to invertebrate life. These pesticides, imidacloprid and fipronil, are used as parasite treatments for flea and tick infestations in cats and dogs, using ‘spot-on’ formulas and flea collars. This is despite these chemicals being banned for agricultural use in 2018 due to their toxicity to bees and other ...
