Researchers have published a simple trick that improves the accuracy of techniques that help us understand how external variables – such as temperature – affect gene activity in plants. “There are really two contributions here,” says Colleen Doherty, corresponding author of a paper on the work and an associate professor of molecular and structural biochemistry at North Carolina State University. “First, we’re raising the visibility of a problem that many of us in the ...

The root system is crucial for plants to absorb water and nutrients, with in situ root research providing insights into root phenotypes and dynamics. While deep-learning-based root segmentation methods have advanced the analysis of root systems, they require extensive manually labeled datasets, which are labor-intensive and time-consuming to produce. Current methods of in situ root observation vary in their effectiveness. Moreover, traditional root image recognition methods face challenges such as subjectivity and ...

About The Study: The findings of this study of 4,515 adolescents suggest that in-person schooling and several coping behaviors (caring for one’s body, exercising, and engaging in healthy behaviors) were associated with significantly higher positive affect and lower perceived stress during the COVID-19 pandemic among adolescents with high adverse childhood experiences (ACEs). Adolescents with high ACEs demonstrated especially greater mental health scores when they reported in-person schooling. Future studies should build on these findings to identify clinical and school-based mental health protective ...

Chlorophyll a fluorescence (ChlF) has been a pivotal tool in understanding plant photochemistry, offering insights into the energy transfer processes within chloroplasts and the efficiency of Photosystem II (PSII). Researchers have relied on quantifying ChlF through specific measures such as F0, Fm, and Fv under various lighting conditions to assess photosynthetic activities. Nonetheless, the technique encounters obstacles owing to the intrinsic uncertainties in gauging the absolute magnitude of ChlF and the fluctuation in baseline levels affected by environmental conditions. This complicates the interpretation of ...

Allergic transfusion reactions (ATRs), a potentially life-threatening side effect of blood transfusions with unclear mechanisms, may be linked to food allergies in pediatric patients as per a recent study by scientists from Japan. They found that ATRs may be triggered by the presence of allergens in the donor’s blood, influenced by their pre-donation diet. These findings could pave the way for safer blood transfusions through the development of preventive measures and countermeasures for ATRs. Blood transfusions are often life-saving procedures in various medical settings. They are required not only after severe blood loss ...

Computers work in digits — 0s and 1s to be exact. Their calculations are digital; their processes are digital; even their memories are digital. All of which requires extraordinary power resources. As we look to the next evolution of computing and developing neuromorphic or “brain like” computing, those power requirements are unfeasible. To advance neuromorphic computing, some researchers are looking at analog improvements. In other words, not just advancing software, but advancing hardware too. Research from the University of California San Diego and UC Riverside shows a promising new way to store and transmit information ...

DALLAS (SMU) – What exactly happens at the tiny scale at which individual atoms exist and interact? SMU chemist Elfi Kraka and her colleagues have been working on developing a computational tool aimed at providing answers to that mystery. Mathematical functions used to calculate the potential energy of a system of atoms are called interatomic potentials. Machine learning interatomic potentials (MLIP)s have become an efficient and less expensive alternative to traditional quantum chemical simulations, which even on today’s high-performance computing often become out of reach for larger ...

Although women have breastfed since the beginning of time, there is very little scientific research on how exercise affects breast milk. Online forums for pregnant women and new mothers are full of questions about this exact issue: Can exercise cause breast milk to go sour? What happens to breast milk if you do high-intensity interval training? Will strenuous exercise affect your milk supply? “There are so many myths about exercise and breast milk. We simply need more knowledge,” says researcher Trine Moholdt at the Norwegian University of Science and Technology (NTNU). She heads several international research projects ...

Residential heating by coal has for decades been the major contributor to the high levels of air pollution in Krakow, Poland. New research finds a nearly 40 percent decline in the annual average concentration of respirable particulate matter (PM2.5) in Kraków, Poland, between 2010 and 2019 following the implementation of policies targeting emissions from the burning of coal and other solid fuels. Researchers show the improvement in air quality translated to substantial benefits for children’s outcomes, including fewer cases of asthma and better birth outcomes. The ...

Nagoya University researchers and their colleagues in Japan have found that middle-age obesity is caused by age-related changes in the shape of neurons in the hypothalamus, a region of the brain that controls metabolism and appetite. A protein called melanocortin-4 receptor (MC4R) detects overnutrition and regulates metabolism and appetite to prevent obesity. According to their study in rats, MC4Rs were concentrated in primary cilia (antenna-like structures) that extend from a couple of groups of hypothalamic neurons. The study also showed that the primary cilia became shorter with age, which decreased MC4Rs accordingly, ...

A four-year study by Dartmouth researchers captures the most in-depth data yet on how college students' self-esteem and mental health fluctuates during their four years in academia, identifying key populations and stressors that the researchers say administrators could target to improve student well-being. The study also provides among the first real-time accounts of how the coronavirus pandemic affected students' behavior and mental health. The stress and uncertainty of COVID-19 resulted in long-lasting behavioral changes that persisted as a "new normal" even as the pandemic diminished, including feeling more stressed, less socially engaged, and sleeping more. The ...

Participation in recreational activities — including golfing, gardening or yard work, woodworking and hunting — may be associated with an increase in a person’s risk for developing amyotrophic lateral sclerosis, or ALS, a Michigan Medicine study finds.  While many activities were associated with increased ALS risk, several were sex specific. The results are published in the Journal of the Neurological Sciences.  “We know that occupational risk factors, like working in manufacturing and trade industries, are linked to an increased risk for ALS, and this adds to a growing literature that recreational activities may also represent ...
