HOUSTON - (March 23, 2021) - Fish that dine on corals may pay it forward with poop.
It's an unexpected twist on coral reef symbiosis, said Rice University marine biologist Adrienne Correa, whose lab discovered coral predator feces are jam-packed with living symbiotic algae that corals depend on for survival. The discovery confirms that poop from coral-eating fish is an important environmental source of symbiotic dinoflagellate algae on coral reefs.
Hummingbird hawkmoths are small insects that hover in the air like hummingbirds when drinking nectar from flowers. Dr. Anna Stöckl from the Biocentre of the Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, is studying the visual performance of these insects. Dr. Stöckl and her doctoral student Ronja Bigge now present their latest findings in the journal Current Biology.
The research team led by Prof. ZHANG Jie from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences made progress on real-time determination of earthquake focal mechanism through deep learning. The work was published in Nature Communications.
Since there are connections between characteristics of the rupture surface of the source fault and seismic wave radiated by the source, it's vital to monitor the earthquake by immediate determination of the source focal mechanism which inferred from multiple ground seismic records.
Hearing loss and other auditory problems are strongly associated with Covid-19 according to a systematic review of research evidence led by University of Manchester and NIHR Manchester Biomedical Research Centre (BRC) scientists.
Professor Kevin Munro and PhD researcher Ibrahim Almufarrij found 56 studies that identified an association between COVID-19 and auditory and vestibular problems.
They pooled data from 24 of the studies to estimate that the prevalence of hearing loss was 7.6%, tinnitus was 14.8% and vertigo was 7.2%.
Scientists from the University of Leeds's Nutritional Epidemiology Group used data from 500,000 people, discovering that consuming a 25g serving of processed meat a day, the equivalent to one rasher of bacon, is associated with a 44% increased risk of developing the disease.
A combination of an array of atomic-level techniques has allowed researchers to show how changes in an environment-sensing protein enable bacteria to survive in different habitats, from the human gut to deep-sea hydrothermal vents.
"The study gives us unprecedented atomic-level insight into how bacteria adapt to changing conditions," says Stefan Arold, professor of bioscience at KAUST. "To obtain these insights, we pushed the limits of three different methods of investigation and combined their results into a unified picture."
The excavation of shell middens off two sites in the Gulf of Mexico and Northern Europe dating back to when the seabed was dry land thousands of years ago, reveal how they can offer new ground-breaking insights into the hidden history of submerged landscapes.
Osaka, Japan - Researchers from the Graduate School of Engineering and Symbiotic Intelligent Systems Research Center at Osaka University used motion capture cameras to compare the expressions of android and human faces. They found that the mechanical facial movements of the robots, especially in the upper regions, did not fully reproduce the curved flow lines seen in the faces of actual people. This research may lead to more lifelike and expressive artificial faces.
Patient care by a single primary care physician is associated with many health benefits, including increased treatment adherence and decreased hospital admissions and mortality risk. But can the relationship built between doctor and patient also lead to unnecessary care?
Durham, NC - The standard of treatment for bone tumors is often two-fold: surgery to remove the cancerous section followed by radiation therapy to ensure all the cancerous cells have been killed off. This is an effective way to defeat bone tumors; however, it often results in large bone defects and hampers wound healing because of extensive tissue cutoff and irradiation-induced tissue damage. A new study published in STEM CELLS Translational Medicine demonstrates how stem cells primed with ferulic acid can repair such bone damage and how this occurs.
National work-family policies that give lower-income families more time together while allowing them paid time off are more effective for children's psychological health than cash transfers, according to a study of developed nations led by Baylor University.
In a study of about 200,000 children in 20 developed nations, the United States ranked lowest in overall policies aimed at helping parents support children.
People are not very nice to machines. The disdain goes beyond the slot machine that emptied your wallet, a dispenser that failed to deliver a Coke or a navigation system that took you on an unwanted detour.
Yet USC researchers report that people affected by COVID-19 are showing more goodwill -- to humans and to human-like autonomous machines.
Announcing a new article publication for BIO Integration journal. In this review article the authors Oliver K. Semisch-Dieter, Andy H. Choi and Martin P. Stewart from the University of Technology Sydney, Ultimo, NSW, Australia discuss the use of biomaterials in dental implants.
A team of researchers from Tübingen and Israel uncovers how brain structures can maintain function and stable dynamics even in unusual conditions. Their results might lay the foundations for better understanding and treating conditions like epilepsy and autism.
An international team of interdisciplinary researchers has identified mathematical metrics to characterize the fragility of financial markets. Their paper "Network geometry and market instability" sheds light on the higher-order architecture of financial systems and allows analysts to identify systemic risks like market bubbles or crashes.
