With the application of a novel three-dimensional imaging technology, researchers at Karolinska Institutet in Sweden have discovered that one portion of the autonomic nervous system in the liver undergoes severe degeneration in non-alcoholic fatty liver disease. The study, which is conducted in mice and human liver tissue, shows that the degeneration of nerves is correlated with the severity of liver pathology. The results are being published in the journal Science Advances.
The building sector in the U.S. accounts for 39 percent of energy use, with commercial buildings responsible for about half of that. As cities grapple with climate change, making commercial buildings more efficient is a key part of the solution.
FRANKFURT/HANNOVER. The international team of geoscientists led by Prof. Silke Voigt from the Goethe University Frankfurt, Prof. Ireneusz Walaszczyk from the University of Warsaw and Dr André Bornemann from LBEG have thoroughly investigated 40 metres of the geological strata sequence in the former limestone quarry at Hasselberg.
An international team of scientists has reported strong indications of freshened groundwater offshore the coastline between Valletta and Marsascala, in the south-east of Malta.
This discovery is based on an oceanographic expedition carried out in 2018.
Seismic reflection profiles acquired during this expedition were used to generate a geological model of the seafloor offshore the Maltese Islands, whereas electromagnetic surveying was carried out to identify resistivity anomalies, or high values of electromagnetic resistivity beneath the seafloor.
In a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2021.200030 , Researchers led by Professor Liu Yan from Xidian University, China and Professor Gan Xuetao from Northwestern Polytechnical University, China consider generation and application of the high-Q resonance in all-dielectric metasurfaces.
Hematopoietic cell transplantation (HCT) is a recognized treatment option for certain blood and bone marrow cancers as well as some autoimmune and hereditary disorders. Performed to replace or modulate the body's malfunctioning hematopoietic system (which produces blood cells) or a compromised immune system following a medical condition or treatment, HCT can be autologous or allogenic. In autologous HCT, a patient's own stem cells are injected into the bloodstream, while in allogenic HCT donor stem cells are used.
The Alum Shale of Northern Europe not only has an eventful history of formation, connected with the microcontinent Baltica, it also holds great potential as an object of investigation for future research questions. Geologists use the rock to reconstruct processes of oil and gas formation, and even possible traces of past life on Mars can be identified with its help. Researchers at the German Research Centre for Geosciences Potsdam GFZ, together with colleagues from Canada, China, Switzerland and Denmark, have summarised the state of knowledge about the multi-layered rock.
Since early 2019, researchers have been recording and analysing marsquakes as part of the InSight mission. This relies on a seismometer whose data acquisition and control electronics were developed at ETH Zurich. Using this data, the researchers have now measured the red planet's crust, mantle and core - data that will help determine the formation and evolution of Mars and, by extension, the entire solar system.
Mars once completely molten
Around 470 million years ago, plants began to conquer the terrestrial surfaces. The first examples had a small axis terminated by a structure capable of forming spores, almost like current mosses. The appearance of plant organs mediated the explosive radiation of land plants, which shaped the surface of our planet and allowed the establishment of terrestrial animal life.
Key Takeaways
A survey of American College of Surgeons members found almost two-thirds treat firearm injuries and more than 85 percent support the organization advocating for policies to reduce firearm-related injuries.
Forty-two percent of ACS members keep firearms in their homes and nearly one-third (32 percent) of surgeon firearm owners store firearms unlocked and loaded.
Survey findings will enable the ACS to identify ways to engage all members, including gun owners, and advocate for initiatives that prevent firearm-related injuries.
