Stethoscope, meet AI – helping doctors hear hidden sounds to better diagnose disease
AI technology can identify the hidden differences in the sounds of healthy and damaged hearts and use them to diagnose disease before traditional acoustic changes like murmurs even appear. Instead of relying on the presence of extra or abnormal sounds to diagnose disease, AI can detect differences in sound that are too faint or subtle for the human ear to detect.
An AI Assistant Can Interpret Those Lab Results for You
Many patients are using large language models, or LLMs, like OpenAI’s ChatGPT, Anthropic’s Claude, and Google’s Gemini, to interpret their records. That help comes with some risk, though.
‘A New Era’ of Cancer Therapies
Now experts say that new therapies are beginning to surpass challenges that previous treatments couldn’t, providing safer, more targeted delivery directly to tumors. These include drugs that contain radioactive substances, called radiopharmaceuticals, which are used to diagnose or treat cancer; medications that can influence the genes that spur or suppress tumor growth; and therapeutic cancer vaccines.
Stem cell therapy reverses type 1 diabetes in world first
This achievement is being hailed as a major medical breakthrough, as it offers a potential cure for a disease that, until now, could only be managed but not cured.
DNA from Ancient Viruses Helps Many Cancers Grow
Cancer cells use all sorts of tricks and trades to aid their growth and survival. Now a new study shows that many kinds of cancer pull an unusual card to support their growth: DNA left over from ancient viruses.
Self-adjusting brain pacemaker may help reduce Parkinson’s disease symptoms
Implanted device responds to changes in brain biomarkers of Parkinson’s symptoms by adjusting stimulation, allowing the treatment to be tailored to a patient’s needs in real time.
AI inconsistently assesses cardiac risk from chest pain – UW study finds
Tasked to interpret data associated with patient complaints of nontraumatic chest pain, the ChatGPT-4 large language model performed poorly against two standard tools that doctors use to predict risk of a cardiac event.
AI shown to dramatically speed protein engineering – UW study
Protein engineering scientists have been able to design more efficient proteins using machine learning quickly, dramatically shortening a process that typically takes months to years of trial and error.
First Cancer TIL Therapy Gets FDA Approval for Advanced Melanoma
In this treatment, immune cells from the patient’s tumor are collected and expanded in culture and then infused back into the patient.
By looking for fragments of DNA that have escaped from tumors into the bloodstream, or circulating tumor DNA (ctDNA), doctors may be able to identify which of their patients with colorectal cancer need chemotherapy after surgery.
Several companies are testing brain implants – why is there so much attention swirling around Neuralink? Two professors unpack the ethical issues
Putting a computer inside someone’s brain used to feel like the edge of science fiction. Today, it’s a reality. Academic and commercial groups are testing “brain-computer interface” devices to enable people with disabilities to function more independently. Two two scholars at the University of Washington School of Medicine – Nancy Jecker, a bioethicst, and Andrew Ko, a neurosurgeon who implants brain chip devices – discuss the ethics of this new horizon in neuroscience.
Nobel prize in medicine awarded to mRNA pioneers – here’s how their discovery was integral to COVID vaccine development
Dr Katalin Karikó and Dr Drew Weissmanhave been awarded the Nobel Prize for their discoveries into mRNA biology. The pair were the first to discover a way of modifying mRNA that allowed it to successfully be delivered to cells and replicated by them. Their discovery was not only integral to COVID-19 vaccine development, but may also lead to the development of many other therapies – such as vaccines for cancer.
Monitoring brainwaves to track how patients with depression respond the treatment
Depression recovery can be hard to measure − new research on deep brain stimulation shows how objective biomarkers could help make treatment more precise Christopher Rozell, Georgia Institute of Technology and Sankaraleengam Alagapan, Georgia Institute of Technology It can be challenging…
Experts Debate the Risks of Made-to-Order DNA
By one expert’s estimate, perhaps 30,000 scientists worldwide have the skills to build a strain of pandemic influenza, provided they can find someone to synthesize the DNA for them. The consequences of unleashing such a pathogen could be catastrophic.
The ethics of brain-computer interfaces lag behind the science, write a philosopher and a neurosurgeon from UW.
Researchers are exploring nonmedical brain-computer interface applications in many fields, including gaming, virtual reality, artistic performance, warfare and air traffic control.
