Research into the hearts of zebrafish, a pet shop staple marked by their eponymous stripes, has shed light on ways the human heart muscle could be healed following damage.
A team of researchers led by Neil Chi, MD, PhD, professor of medicine at University of California San Diego School of Medicine, and Manuel Galvez-Santisteban, PhD, a postdoctoral scientist working alongside him, have pinpointed a signaling pathway in zebrafish heart cells that leads to the regeneration of damaged tissue. The findings are published in the June 25, 2019 issue of eLife.
Like a symphony, multiple brain regions work in concert to regulate the need to eat. University of Arizona researchers believe they have identified a symphony conductor - a brain region that regulates appetite suppression and activation - tucked within the amygdala, the brain's emotional hub.
The UA Department of Neuroscience team found the neurocircuitry controlling appetite loss, called anorexia, said assistant professor Haijiang Cai, who is a member of the BIO5 Institute and heads up the neuroscience lab that ran the study.
COLUMBUS, Ohio--A shortage of high school physics teachers has led to teachers with little-to-no physics training taking over physics classrooms, causing additional stress and job dissatisfaction for those teachers--and a difficult learning experience for their students.
But new research indicates that focused physics professional development for teachers--even those who have no prior physics training--can lead to better experiences for both students and teachers, and can improve students' understanding of physics concepts.
New Stanford linguistics research has analyzed how Republicans and Democrats use different language when discussing mass shootings on social media and found that Republicans talk more about the shooter and Democrats focus more on the victims.
If a man is handy with the vacuum cleaner, isn't averse to rustling up a lush family meal most nights after he's put on the washing machine having popped into the supermarket on his way home then it's more than likely his partner will have her own bank account.
A new study by Lancaster University reveals the way in which couples manage their money tells 'a tale of two marriages' in the UK today.
WASHINGTON--Women exposed to triclosan are more likely to develop osteoporosis, according to a study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
Vienna, 25 June 2019: The adverse effect of maternal smoking during pregnancy is well established and associated with several negative neonatal outcomes (such as low birth weight and preterm birth). It is also evident in some studies that the semen quality of men exposed to prenatal maternal smoking is generally more impaired than that of unexposed men.(1) However, there is little known about the effect of paternal smoking in the time leading up to and during pregnancy.
PHILADELPHIA - Shortening the length of rotations in a medical intensive care unit (MICU) from the traditional 14-consecutive day schedule to only seven days helps mitigate burnout among critical care physicians, according to a new Penn Medicine pilot study. The study, published today in the American Journal of Respiratory and Critical Care Medicine, is the first to validate the efficacy of a truncated rotation in reducing the rate of burnout among critical care physicians.
New research discovers employees who view pornography aren't just costing companies millions of dollars in wasted time, they're causing harm to the company.
A study published in the Journal of Business Ethics finds that viewing pornography at work increases unethical behavior. Given unethical employee behavior is linked to a number of negative organizational outcomes -- like fraud and collusion -- employee pornography consumption is putting organizations at risk.
The frilled dragon exhibits a distinctive large erectile ruff. This lizard usually keeps the frill folded back against its body but can spread it as a spectacular display to scare off predators. Researchers at the University of Geneva (UNIGE), Switzerland, and the SIB Swiss Institute of Bioinformatics report in the journal eLife that an ancestral embryonic gill of the dragon embryo turns into a neck pocket that expands and folds, forming the frill.
East Hanover, NJ. June 25, 2019. A recent study by Kessler Foundation researchers provided new findings about the nature of social cognitive deficits in the population with progressive multiple sclerosis (MS). The article, "Cognitive but Not Affective Theory of Mind Deficits in Progressive MS", (doi: 10.1017/S1355617719000584) was epublished on June 10, 2019 by the Journal of the International Neuropsychological Society.
Astronomers have a new tool in their search for extraterrestrial life - a sophisticated bot that helps identify stars hosting planets similar to Jupiter and Saturn.
These giant planets' faraway twins may protect life in other solar systems, but they aren't bright enough to be viewed directly. Scientists find them based on properties they can observe in the stars they orbit. The challenge for planet hunters is that in our galaxy alone, there are roughly 200 billion stars.
LA JOLLA, CA - Sorting through individual immune cells is a handy way to see how the body responds to disease. For years, researchers around the world have used a technique called flow cytometry to separate different types of immune cells, such as T cells, B cells and monocytes. But occasionally they'd see two cells stuck together as a "doublet." Many regarded doublets as an artefact of the flow cytometry process, and it was common place to "dump" those conjoined cells before gathering data.
People who care for their elderly parents outside of their full-time jobs -- and are unpaid for their help -- experience considerable disruption of their workplace routines. Many are not getting employer support because it is not offered or because they do not feel able to use it, even if it is available, according to a Baylor University researcher.
Abstract: The function of protein machines in biological cells is so complex that even supercomputers cannot predict their cycles at atomic detail. But, as demonstrated in this review article, many aspects of their operation at mesoscales can be already revealed by exploring simple mechanical models, amenable for simulations on common computers. The authors also show how artificial protein-like structures with machine properties can be designed.
