Emissions tied to the international trade of agricultural goods are rising
Earth system scientists at the University of California, Irvine and other institutions have drawn the clearest line yet connecting consumers of agricultural produce in wealthier countries in Asia, Europe and North America with a growth in greenhouse gas emissions in less-developed nations, mostly in the Southern Hemisphere. In a paper published today in Science, the […]
Opinion | A 20-Step Manifesto for Better Healthcare Quality
Our country, the richest society in human history, features a healthcare system — avoidable by none — in which the level of dysfunction is beyond compare. The version of healthcare good enough for the people we call patients will not be reached passively. Whether we improve enough to give our patients and communities the quality […]
EHR Pop-Ups Spur Better GDMT Implementation in Heart Failure
WASHINGTON — A large health system took advantage of its electronic health records (EHR) software to increase utilization of guideline-directed medical therapy (GDMT) in the outpatient setting. In the PROMPT-HF study, clinicians randomized to a clinical decision-support intervention got electronic alerts every time they accessed the EHR of a heart failure outpatient not on one […]
What Drives Post-COVID Cognitive Changes?
New research released today suggested that an over-stimulated immune system — possibly triggered by ongoing vascular injury and repair — may be behind persistent post-COVID cognitive changes. In preliminary work that will be presented at the American Academy of Neurology annual meeting, researchers led by Joanna Hellmuth, MD, MHS, of the University of California San […]
Artificial hail for more accurate weather forecasts
When the low-pressure system dubbed Bernd decided to park itself over part of Central Europe in the summer of 2021, the hazards associated with excessive rainfall events were made dramatically apparent in the form of the resultant catastrophic flooding. Weather records show that extreme natural occurrences such as drought, but also heavy rainfall and hail […]
Study shows how bioactive substance inhibits important receptor: Results raise hope for new drugs against cancer and brain diseases
The A2A receptor regulates how vigorously the innate immune system attacks diseased cells. Researchers at the University of Bonn have now been able to show for the first time how an important inhibitor binds to the receptor. In the future, the results will facilitate the targeted search for molecules that give the innate immune system […]
Opinion | Residency Is Broken. We’re Unionizing to Fix It.
On its website, UMass Memorial Health states that the hospital system was created to “make health and healthcare available to everyone.” This mission is made possible by the “people of UMass Memorial Health” and their “relentless pursuit of healing in all its forms.” As frontline resident physicians who work day in and day out to […]
Conversion process turns pollution into cash: Converting carbon dioxide to ethylene holds commercial promise, professor says
Engineers at the University of Cincinnati have developed a promising electrochemical system to convert emissions from chemical and power plants into useful products while addressing climate change. UC College of Engineering and Applied Science assistant professor Jingjie Wu and his students used a two-step cascade reaction to convert carbon dioxide to carbon monoxide and then […]
Fluorescence-Guided Lumpectomy Shows Promise
A fluorescence-guided imaging system could improve intraoperative detection of residual breast cancer in women undergoing lumpectomy, a prospective single-arm study suggested. The system, which incorporates the activatable fluorescent imaging agent pegulicianine (LUM015) had higher sensitivity, though lower specificity, than standard pathology review of the main lumpectomy specimen, reported Shelley Hwang, MD, MPH, of Duke University […]
New screening system may point the way to clean, renewable hydrogen power
A new, highly sensitive system for detecting the production of hydrogen gas may play an important role in the quest to develop hydrogen as an environmentally friendly and economical alternative to fossil fuels, according to Penn State scientists. “We have built a new system for detecting hydrogen evolution that is the most sensitive in the […]
