When active sport is at the centre of a profession or education, pain is often a constant companion - pain being defined in this case as physical and psychological symptoms. "One in three top athletes suffers significant pain," explains Dr. Johannes Fleckenstein, private lecturer at Goethe University. This is an issue that generally tends to be neglected, but he has made it the main focus of his classes.
It is a longstanding challenge to be able to control biological systems to perform specific tasks. In a paper published in Nature Physics, researchers at the Niels Bohr Institute, University of Copenhagen - in collaboration with groups in US and UK, have now reported doing just that. They have found a way to control bacteria to transport microscopic cargos. Bacteria form the largest biomass in the world, larger than all the animals and plants combined, and they are constantly moving, but their movement is chaotic.
New Rochelle, NY, March 23, 2020--A new systematic review and meta-analysis showed a small but significant reduction in subjective pain scores for cannabinoid treatment compared to placebo in patients experiencing acute pain. No increase in serious adverse events suggested the safety of using cannabinoids to treat acute pain, according to the study published in Cannabis and Cannabinoid Research, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
The cytoskeleton is a permanent construction site: it consists of protein filaments that are continually lengthening and shortening in a dynamic process. Through these remodeling processes, the cell can change its shape and even move to a new location. In this way, it guides fundamental processes, such as cell division and differentiation, and processes at a higher level in the organism, such as embryonic development and wound healing.
Prolonged fear and anxiety brought on by major stressors, like the coronavirus pandemic, can not only take a toll on a person's mental health, but may also have a lasting impact on a man's sperm composition that could affect his future offspring. That is the finding of a provocative new study published in the journal Nature Communications by researchers at the University of Maryland School of Medicine.
Philadelphia, March 23, 2020 - A new study led by researchers at Children's Hospital of Philadelphia (CHOP) shows that a set of simple questionnaires can help clinicians and families better evaluate the quality of life of people diagnosed with autism spectrum disorder (ASD). The newly-developed tool is designed for children, adolescents, and adults on the autism spectrum, and early findings show where clinicians can learn more about how to support the needs of autistic individuals by directly asking them these critical questions.
What The Study Did: This study used data and brain imaging from a randomized clinical trial for older adults who are cognitively unimpaired and examined brain changes, including the presence of biomarkers for Alzheimer disease, between those with sleep-disordered breathing and those without.

KAIST researchers have developed a novel wearable strain sensor based on the modulation of optical transmittance of a carbon nanotube (CNT)-embedded elastomer. The sensor is capable of sensitive, stable, and continuous measurement of physical signals. This technology, featured in the March 4th issue of ACS Applied Materials & Interfaces as a front cover article, shows great potential for the detection of subtle human motions and the real-time monitoring of body postures for healthcare applications.
In Southeast Asia, the fruit, flowers, and leaves of Indonesia's "Melinjo" tree are traditional foods. Researchers from Kumamoto University, Japan who study plants from around the world for useful medicinal properties have found that Melinjo seed extract (MSE) stimulates the production of adiponectin, a beneficial hormone that improves obesity and diabetes. They also discovered that individual genotype differences were responsible for variations in its efficacy.
Tsukuba, Japan - In most cases, taking a break isn't the most efficient way of getting a job done. But in a study published this week in iScience, researchers from Japan's University of Tsukuba have uncovered the regulatory pathway governing the first of two breaks that are essential for proper germline cell development in model species Drosophila melanogaster.
Fuel cells and water electrolyzers that are cheap and efficient will form the cornerstone of a hydrogen fuel based economy, which is one of the most promising clean and sustainable alternatives to fossil fuels. These devices rely on materials called electrocatalysts to work, so the development of efficient and low-cost catalysts is essential to make hydrogen fuel a viable alternative. Researchers at Aalto university have developed a new catalyst material to improve these technologies.
Photodetectors, a key optoelectrical component for the translation of optical signals into electrical signals, are of great interest to a wide range of industrial production, military affairs, biochemical detection, optical communication. Organic-inorganic hybrid perovskites (OIHPs), owing to their excellent optical and electrical properties including tunable direct bandgap, preeminent optical absorption, high carrier mobility, and low trap density, have attracted immense research interest for thin-film solar cells, LEDs, and photodetectors.
As average temperatures rise every year, it is no longer rare to see plants flower as early as February. Behind this phenomenon is a complex of proteins whose activity is controlled by temperature changes, as has just been demonstrated by researchers from the Cell and Plant Physiology Laboratory (CNRS / CEA / INRAE / Université Grenoble Alpes) and their partners.* Composed of three proteins (LUX, ELF3, and ELF4), the Evening Complex regulates the expression of genes involved in plant growth and flowering, as a function of exterior temperatures.
WASHINGTON, March 23, 2020 -- Constantly being told to wash your hands? Us, too. So we're diving into the chemistry behind why soap is so effective against viruses like the coronavirus that causes COVID-19: https://youtu.be/K2pMVimI2bw.
