ANN ARBOR--It's one of the greatest and longest-running mysteries surrounding, quite literally, our sun--why is its outer atmosphere hotter than its fiery surface?
University of Michigan researchers believe they have the answer, and hope to prove it with help from NASA's Parker Solar Probe.
A trip to an intensive care unit can be more than twice as costly as a stay in a non-ICU hospital room, but a new study finds intensive care is still the right option for some vulnerable patients after a severe heart attack.
The difficulty lies in determining which people are best served in the ICU while they recover.
A physicist at The University of Texas at Arlington has proposed a new concept for treating cancer cells, further advancing the University's status as a leader in health and the human condition.
In a recently published paper in the journal Nanomedicine: Nanotechnology, Biology and Medicine, UTA physics Professor Wei Chen and a team of international collaborators advanced the idea of using titanium dioxide (TiO2) nanoparticles stimulated by microwaves to trigger the death of cancer cells without damaging the normal cells around them.
Scientific research usually takes months to be published by academic journals, and once it is, many of the papers can only be read by scientists from wealthy institutes that subscribe to the journals. Over the years, there have been various attempts to make research more widely available, but most papers remain behind paywalls and scientists complain that the peer review process at journals now takes longer than ever.
New research has found no increased risk of congenital malformations associated with treatment with radiotherapy or chemotherapy in children of fathers with testicular cancer. The study, by Yahia Al-Jebari of Lund University, Sweden and colleagues, is published in the open-access journal PLOS Medicine on June 4, 2019. It followed 4,207 children of 2,380 fathers and finds that those conceived after treatment were not at a greater risk of congenital malformations than those conceived before.
In the online world, where incivility is all too common, new research from the McCombs School of Business at The University of Texas at Austin found that being polite is golden, at least when individuals who pose questions online get to choose the "best answer."
This "politeness bias" was uncovered by Andrew Whinston, McCombs professor of information, risk and operations management, and his collaborators and former Ph.D. students, the University of Rochester's Huaxia Rui and the University of Connecticut's Shun-Yang Lee.
TORONTO, JUNE 4, 2019 - For children with severe epilepsy, surgery is the last resort used to prevent seizures but the treatment can often come with the risk of both visual and cognitive impairments. Now, a new study funded by the National Eye Institute and jointly led by researchers at York University's Faculty of Health and Carnegie Mellon University, finds that the brains of children with severe epilepsy can compensate by rewiring for missing regions of the visual cortex after surgery.
Research at the University of York has shown that women are underrepresented in research into links between cannabis and psychosis, which could limit understanding of the impact of the drug.
In a review of scientific literature over a number of years, Ian Hamilton from the University of York's Department of Health Sciences, found that the majority of research reflects the experience of male cannabis users, with very limited information on how women react to the drug.
Growing evidence shows that the brain's dopamine system, which drives motivation, is directly affected by chronic, low-grade inflammation. A new paper proposes that this connection between dopamine, effort and the inflammatory response is an adaptive mechanism to help the body conserve energy.
Trends in Cognitive Sciences published the theoretical framework developed by scientists at Emory University. The authors also provided a computational method to experimentally test their theory.
Best practices of nucleic acid amplification tests for the diagnosis of clostridioides (clostridium)
Washington, DC - June 3, 2019 - A new review looks at the challenges of testing for Clostridioides (Clostridium) difficile infection (CDI) and recommendations for newer diagnostic tests. Accurate diagnosis of CDI is critical for effective patient management and implementation of infection control measures to prevent transmission. The research is published this week in the Clinical Microbiology Reviews.
Conditions in Arctic waters are among the most extreme in the world. Strong winds and currents powerfully push ice across vast distances, resulting in large ridges reaching tens of metres in height. At the same time, global warming and increased human presence have added new pressures in these northern environments. Yet the mechanisms behind the effects of ice on physical structures -- particularly over the long term -- have remained an open question in a time of continuous environmental change.
CHAMPAIGN, Ill. -- As foxes and coyotes adapt to urban landscapes, the potential for encounters with humans necessarily goes up. A team of scientists is taking advantage of this fact to enlist the eyeballs and fingertips of humans - getting them to report online what they see in their own neighborhoods and parks.
One goal of the research, reported in the journal Landscape and Urban Planning, is to determine how information gathered by "citizen scientists" stacks up against data more laboriously collected by researchers who study canids like foxes and coyotes.
Chemical analyses of meteorites allow for a better estimation of the chemical composition of the Earth and its potential building blocks. That is the result of a study conducted by a research team from the Institutes of Geology and Mineralogy at the Universities of Cologne and Bonn. The results have appeared in the current issue of 'Nature Geoscience'.
ROCKVILLE, Md. - June 4, 2019 - The Association for Molecular Pathology (AMP), the premier global, molecular diagnostic professional society, expressed serious concerns with Congress' recent proposal to amend Section 101 of the Patent Act. If enacted, the draft legislation would overturn 150 years of patent case law and permit patenting of human genes and naturally-occurring associations between genes and diseases.
A bad night's sleep may result in a spike in blood pressure that night and the following day, according to new research led by the University of Arizona.
The study, to be published in the journal Psychosomatic Medicine, offers one possible explanation for why sleep problems have been shown to increase the risk of heart attack, stroke and even death from cardiovascular disease.
The link between poor sleep and cardiovascular health problems is increasingly well-established in scientific literature, but the reason for the relationship is less understood.
