Research has shown that, when nurses feel they are being prevented from taking a morally justifiable action or achieving an ethical outcome, it contributes to poor mental health, burnout, and intent to leave one’s job. Surveys from the COVID-19 pandemic found that a shortage of personal protective equipment (PPE) and lack of perceived support from hospital administrators were associated with higher levels of this moral distress. University of Pennsylvania School of Nursing researchers and their collaborators hypothesized that nurses working in hospitals where Black patients predominantly access care—which they call Black-serving hospitals, or ...

In a recent study, scientists have unlocked the secrets behind the diverse flavors of table grapes. By examining 38 different cultivars, the research offers unprecedented insights into the volatile compounds that shape our taste experiences, paving the way for enhanced grape quality and flavor. The flavor of table grapes, influenced by various volatile compounds, plays a significant role in consumer preference and marketability. Traditional flavor analysis methods often fail to capture the complexity and diversity of grape flavors, especially in hybrid varieties. Conventional flavor classifications like muscat and foxy are insufficient for describing the wide range of flavors ...

Unlocking the secrets of nature, a pioneering study has pinpointed a gene mutation with profound implications for plant height and stress tolerance. The discovery lies in the CpDWF5 gene, whose alteration leads to a compact squash plant with a unique resistance to salt stress, marking a leap forward in agricultural science. In the quest to bolster crop yields and fortify plants against environmental stressors, the delicate interplay of phytohormones stands as a keystone. Yet, our grasp of these genetic levers, particularly those dictating plant stature and resilience to salinity, remains tenuous. Bridging ...

FOR IMMEDIATE RELEASE By studying mutations in yeast and human cells, Johns Hopkins Medicine scientists say they have found that biochemical bonds between fats and proteins in the mitochondrion, the cell’s powerhouse, play a crucial role in how our cells produce energy. The study results, published June 5 in The EMBO Journal, shed new light, researchers say, on the way the altered mitochondrial membranes found in people with metabolic diseases such as Barth syndrome, a rare genetic disorder that weakens the heart, fail to enable cellular power production. Metabolism is a set of biochemical reactions central to making energy to fuel life and to getting rid of substances a body no ...

Where there’s smoke, there’s not necessarily fire. Wildfire smoke, sometimes drifting from hundreds of miles away, touched nearly every lake in North America for at least one day per year from 2019 to 2021, according to a study from the University of California, Davis.  Even more significantly, the study, published in the journal Global Change Biology, found that 89% of the lakes in North America experienced smoke for more than 30 days during each of those three years of intense wildfire activity. “That was surprising, even ...

Giving a regular cash payment to the entire world population has the potential to increase global gross domestic product (GDP) by 130%, according to a new analysis published June 7 in the journal Cell Reports Sustainability. Researchers suggest that charging carbon emitters with an emission tax could help fund such basic income program while reducing environmental degradation. “We are proposing that if we can couple basic income with environmental protection, we can save two birds with one stone,” says first author U. Rashid Sumaila of the University of British Columbia in Vancouver. Sumaila has been working on ending harmful fishery subsidies worldwide, but many people who rely ...

Hand osteoarthritis mainly affects the distal interphalangeal, proximal interphalangeal, and thumb base joints,1 leading to joint pain, aching, and stiffness. Criteria developed by the American College of Rheumatology (ACR) in 1990 are useful, but they cannot distinguish between interphalangeal or thumb base disease, and this is important since these two phenotypes may require different treatment strategies.   To address this, EULAR and a team of leading experts in the field set out to develop new classification criteria sets that include radiographic features. Early phases of the project used observational data to identify self-reported, ...

Thousands of particles of light can merge into a type of “super photon” under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers at the University of Bonn have now shown that this exotic quantum state obeys a fundamental theorem of physics. This finding now allows one to measure properties of photon Bose-Einstein condensates which are usually difficult to access. The study has been published in the journal Nature Communications. If many atoms are cooled to a very low temperature confined in a small volume, they can become indistinguishable and behave like a single “super particle.” Physicists also call this ...

While the potential for technological emission reduction continues to be released, the main factor affecting China’s carbon emissions is the speed and intensity of economic transformation and industrial restructuring.   A research team of Dr. GU Alun from Tsinghua University in Beijing, China, recently analyzed the correlations ...

Fukuoka, Japan—In a paper published in Geophysical Research Letters, researchers have discovered that the turbulence in the thermosphere exhibits the same physical laws as the wind in the lower atmosphere. Furthermore, wind in the thermosphere predominantly rotates in a cyclonic direction, in that it rotates counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The findings reveal a new unified principle for the Earth’s varied environmental systems and can potentially improve future forecasting of both earth and space weather. One time or another we’ve tuned in to see the latest weather forecast, and while ...

Neurons communicate electrically so to understand how they produce brain functions such as memory, neuroscientists must track how their voltage changes—sometimes subtly—on the timescale of milliseconds. In a new paper in Nature Communications, MIT researchers describe a novel image sensor with the capability to substantially increase that ability. The invention led by Jie Zhang, a postdoctoral scholar in The Picower Institute for Learning and Memory lab of Sherman Fairchild Professor Matt ...

Cells are signalled to have nutrients in excess, and this leads to malfunction and inflammation in organs such as the pancreas, the liver and the kidneys.   The finding, by CNIO researchers, are published in Nature Aging. It suggests that an intervention on the inflammation alone can relieve symptoms and increase survival.   The research has been conducted on animal models, but comparing their molecular processes with blood samples from people in their seventies indicates that they can be extrapolated to human aging. The reality of a population who is ageing at an accelerated rate makes it a priority to understand what happens in the body over time, ...
