">I am James F. Dempsey, Ph.D., Nucl. Chem., developer of new weapons to fight cancer. My team solved “impossible” problems for treating cancer with radiation - while clearly seeing inside the patient - with a linear accelerator inside an MRI scanner, AMA!
The radiation treatment field has invested a lot of research into making better dose distributions and delivering accurately to patients. Many advances have been made in tracking breathing motion, surgically implanting marker or gels in the body, placing balloons in orifices to immobilize tissues, using X-Ray flat-panels detectors to find markers or make “cone-beam” CTs. However, all of these approaches still do not see the actual organs and tumor in real time as they move in the body during therapy. I founded ViewRay to solve this problem. MRI scanners provide the best soft tissue visual clarity of patients organs but they are not compatible with radiotherapy accelerators. People spent decades unsuccessfully trying to combine an MRI and a Radiation beam into a single, effective medically usefully device available to treat patients. In a sense, the MRI scanner and the accelerate do not like each other. The magnetic field generated by the MRI scanner can prevent the accelerator from operating and the accelerator uses radar technology and makes radiofrequency noise that can prevent the MRI from scanning clear images.
So, we took a superconducting MRI and we split it in half opening it up, leaving the imaging volume floating in the middle where we could shoot in radiation beams while scanning. We created magnetic sleeves that could create voids in the magnetic field to protect the accelerator. Then we borrowed ideas from stealth aircraft to absorb the radiofrequency noise and eliminate it. Finally, we developed advanced software to compute and optimize dose, as well as, track tissues with real-time MRI video . This allows us to optimize, reshape, and track moving tissues so we do not miss, which is important to eradicate the tumor and spare healthy tissues. What we call the MRIdian® Linac system was FDA cleared in February of 2017. The MRIdian® an earlier generation system has been treating patients for over 3.5 years and data published at ASTRO 2017 showed significant early results in treating pancreatic cancer, known to be one of the most difficult cancers to effectively treat.

We understand that in the busy list of reddit, both your home page and popular, it's often hard to see a newly posted AMA you might be interested in. As a solution, we've set up a reddit-based program to message you when an AMA is posted. You can even select just the subject areas you are interested in! We won't have access to any of your personal information with this, it's a rather simple program that only works within reddit, so your anonymous account stays anonymous, and anytime you want to cancel the messages a simple 'stop' reply will stop them.

">PLOS Science Wednesday: Hi reddit, we’re Nathan and Stacey, and we published a case study of a patient whose HIV was undetectable and may have been cured after allogeneic stem cell treatment – Ask Us Anything!
Hi Reddit,
My name is Nathan Cummins, and I am the Research Chair in the Division of Infectious Diseases at the Mayo Clinic Rochester. My research focuses on studying how HIV prevents cell death in some cells that it infects, and repurposing drugs to modify those effects. And my name is Stacey Rizza and I am the Chair of the HIV Clinic at Mayo Clinic, Rochester. My work focuses on HIV and solid organ and stem cell transplantation.
We recently published a paper titled “Extensive virological and immunological characterization in an HIV-infected individual following allogeneic stem cell transplant and analytic cessation of antiretroviral therapy: a case study” in PLOS Medicine. This manuscript examined the immunologic and virologic changes that occurred in a patient with chronic HIV infection who was diagnosed with ALL, and who underwent Allo-PBSCT. We found that the amount of HIV that was present in this patient was reduced to undetectable levels, and that his serologic tests for HIV were reverting to negative, suggesting that he may have been cured from HIV infection. Ultimately, we stopped his HIV therapy, and observed no HIV rebound for 288 days following treatment interruption, when a viral species that was unrelated to his pre-transplant virus rebounded.
We will be answering your questions at 1pm ET -- Ask me Anything!

">Hi Reddit, I am Terri Woods of East Carolina University. Ask me anything about the aqueous geochemistry and/or using augmented reality to teach surface geology!
Hi Reddit, I’m Terri Woods! I am an Associate Professor of Geological Sciences at East Carolina University (ECU). In 1971 I entered the University of Delaware with the goal of teaching high-school Spanish. Instead I became fascinated by how things work in the geological world and changed my major. While working on an MS at Arizona, I worked for the Anaconda Copper Company in Tucson and did mineral exploration with them in Montana. My thesis involved microprobe and fluid-inclusion work on a garnet skarn. I interviewed with mining/oil companies but got turned off by comments from interviewers such as; “We are looking for a few good gals”.
Luckily, I got another offer from the USGS in Reston, Virginia to work on the epithermal sulfide deposit at Creede, Colorado. I worked there for 3 years but my husband and I got tired of the DC area and went cruising on our 43-foot wooden sailboat. We ran out of money in St. Petersburg, Florida at a time when geology employment was hard to come by so I worked minimum-wage jobs until Bob Garrels (USF-Marine Science) asked me to run his lab. For the next 5 years I helped Bob with projects such as copper corrosion in sulfate, carbonate and chloride solutions; water chemistry in equilibrium with Australian BIF; C and S cycling through geological time, and compilation of thermodynamic data. I got my Ph.D. in 1988.
That fall I started as a faculty member at ECU. I did lab work on copper corrosion, but students were into hydro-environmental studies so I began investigating the chemistry of water from local aquifers. That research continues, but I have also worked on the impact of reverse-osmosis brine discharge into Albemarle Sound, chemistry of nearby streams, and petrology of aquifer materials. I’ve devoted a lot of time to science outreach. Most recently, I have investigated a technology that helps people understand surficial processes and topographic maps - the Augmented Reality Sandbox: short demo video http://ift.tt/2nbfB4K longer educational video http://ift.tt/2zKMY4i This past spring (2017), I was happy to serve as the scientific consultant for the ACS Reactions video “Why is the Statue of Liberty Green?” https://www.youtube.com/watch?v=_ZSLrXtg1-o
So, Reddit, ask me anything about aqueous geochemistry, copper corrosion, or using augmented reality to teach surface geology.
I’ll be back to start answering your questions at 12pm EST (9am PST; 5pm UTC).

">Science AMA Series: We’re NASA space communications engineers working on technology for the interplanetary internet – Ask Us Anything!
Hi, we're NASA engineers working on space communications technologies that will help create an interplanetary internet. When data travels vast distances like the 30+ million miles to Mars, the potential for delay or disruption is significant! Network disruption in space can happen because of limited contact time and atmospheric effects. NASA communications technology called 'disruption-tolerant networking' (DTN) allows for temporary disruptions and long delays, unlike the familiar computer to computer IP connection. DTN can also provide tremendous benefits to missions closer to Earth and terrestrial applications. That's what we're working on, and it has the potential to improve data transmission for virtually all of NASA's missions.
