Damage to DNA in cancer cells can lead to pieces breaking off chromosomes and floating away, like icebergs cracking off a glacier. Just as icebergs are a threat to ships and their crew, these scattered bits of DNA loom large for physicians and cancer patients by having titanic effects on tumor progression and treatment resistance. https://medicalxpress.com/news/2026-06-patient-derived-deadly-dna-loops.html Mon, 08 Jun 2026 07:20:01 EDT news700115941 Today, HIV can be managed with medical treatment. However, despite 40 years of intensive research, scientists have not yet succeeded in finding a cure for the disease. People with HIV experience a flare-up of the virus only a few weeks after stopping treatment. But now, an international team of researchers, led by scientists at Aarhus University and Aarhus University Hospital, may have moved another step closer to a medication-free existence for the millions living with HIV today. https://medicalxpress.com/news/2023-09-big-hiv.html Mon, 18 Sep 2023 12:11:03 EDT news614257861 For nearly a week last month, people around the world eagerly awaited updates on the saga of the missing Titan submersible. Each moment upped the ante, as the theoretical clock of suspected available oxygen neared zero, until ultimately, the story ended in tragedy with the discovery of debris. https://medicalxpress.com/news/2023-07-drawn-tragedy-psychological-sciences-professor.html Mon, 17 Jul 2023 14:52:03 EDT news608824321 In the ongoing quest to discover which constituents of the immune system provide highly specified protection, scientists have found that a component of the innate immune system is endowed with the capability of guarding the lungs from pneumonia-induced injury. https://medicalxpress.com/news/2023-04-tiny-protein-apparently-titanic-impact.html Thu, 27 Apr 2023 10:53:01 EDT news601811569 A team of researchers at Pohang University of Science and Technology, in the Republic of Korea, working with a colleague from the Georgia Institute of Technology in the U.S. has developed a method for deep brain stimulation without surgery. In their paper, published in the journal Nature Biomedical Engineering, the group describes passing piezoelectric nanoparticles through the blood–brain barrier (BBB) and using bursts of ultrasound to make them produce pulses of electricity. https://medicalxpress.com/news/2023-01-piezoelectric-nanoparticles-deep-brain.html Thu, 05 Jan 2023 09:30:31 EST news592133424 Even as scientists in dozens of disciplines have turned their attention to the urgent needs of the global pandemic, an elite cadre of surgeon-scientists in the United States has been focusing on a potentially deadly brain aneurysm and how to effectively treat it. https://medicalxpress.com/news/2021-12-tiny-device-titanic-impact-neurosurgeons.html Mon, 27 Dec 2021 12:18:42 EST news559829906 A new mutation found in a gene associated with an increased risk of atrial fibrillation poses a significantly increased risk for heart failure in Black people. https://medicalxpress.com/news/2021-05-mutation-afib-heart-failure-people.html Thu, 06 May 2021 03:39:54 EDT news539491178 The coronavirus tightened its grip on the American heartland, with infections surging in the Midwest, some hospitals in Wisconsin and North Dakota running low on space and the NFL postponing a game over an outbreak that's hit the Tennessee Titans football team. https://medicalxpress.com/news/2020-10-hospitals-coronavirus-spikes-midwest.html Thu, 01 Oct 2020 04:36:19 EDT news520745773 For years, computational biologists have sought ways to model how proteins change shape in real time. In the past decade, they've glimpsed the possibilities as new programs and powerful computers came on line, letting researchers learn more about disease mechanisms that once eluded them. https://medicalxpress.com/news/2018-04-team-protein-conformations-paths-autoimmunity.html Thu, 12 Apr 2018 09:03:29 EDT news442742597 Can a legendary investor, the king of on-line retail and a Wall Street financier find a cure for what ails America's health care system? https://medicalxpress.com/news/2018-01-business-titans-health.html Wed, 31 Jan 2018 16:40:01 EST news436638541 For their calculations, researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) will now, starting in 2015, have access to the World's second-fastest computer. The Dresden research initiative is one of 56 projects the US Department of Energy has granted access to Titan as part of their INCITE program. HZDR's 3D simulations of laser-accelerated ions is listed as one of their six 2015 highlights. The Dresden scientists are hoping that the computations will yield new insights that may prove useful in proton-based cancer therapy. https://medicalxpress.com/news/2014-11-supercomputer-titan-hzdr-cancer.html Wed, 26 Nov 2014 10:37:27 EST news336220637
