WASHINGTON, April 28, 2020 -- Growth of high-quality substrates for microelectronic applications is one of the key elements helping drive society toward a more sustainable green economy. Today, silicon plays a central role within the semiconductor industry for microelectronic and nanoelectronic devices.
Hepatocytes are responsible for diverse metabolic activities in a liver. Proper ribosome biogenesis is essential to sustain the function of hepatocytes. There are approximately 200 factors involved in ribosome biogenesis, however, few studies have focused on the role of these factors in maintaining liver homeostasis. The digestive organ expansion factor (def) gene encodes a nucleolar protein Def that participates in ribosome biogenesis.
Overview
The Earth's surface represents a very complex system where a multitude of natural and man-made structures and terrains interact, including forests, water bodies, grasslands, farmlands, mines, and mountains. Over time, these interactions shape the natural habitat and resources that sustain life as we know it. The present distribution of materials on Earth's soils is the result of a long interplay of various driving forces, ranging from geological processes that started millions of years ago to recent mining activity.
Last year, about 30 common shrews from the area around Möggingen had an unusual adventure. Researchers at the Max Planck Institute for Animal Behavior in Radolfzell captured the animals, measured their skulls, and examined their metabolism. The animals were then released back into the wild. This all led to an exciting discovery. The measurements revealed that the animals' metabolism is equally active in summer and winter. Animals that do not hibernate usually require more energy in winter in order to maintain a constant body temperature.
Despite an extreme environment characterized by high pressure, high temperature, strong acidity and low oxygen level which resembles living condition in pre-historic time, hydrothermal vents harbor a diverse amount of creatures - most of which have huge potential for biomedical and other applications. Among other inhabitants of such difficult environment, Scaly-foot Snail, also known as "Sea Pangolin", is of particular interest to marine scientists.
The Molecular Mechanics of the Cardiovascular System group at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), led by Jorge Alegre Cebollada, in partnership with an international scientific team, has generated the first experimental mouse model that allows direct analysis of the mechanical function of proteins in living organisms.
ROCHESTER, Minn. -- People with certain heart diseases may be more susceptible to worse outcomes with COVID-19, but the reason why has remained unknown. New research from Mayo Clinic indicates that in patients with one specific type of heart disease obstructive hypertrophic cardiomyopathy (HCM) the heart increases production of the ACE2 RNA transcript and the translated ACE2 protein.
CAMBRIDGE, MA -- Over the past few decades, there have been a handful of incidents in which manufacturing processes for making protein drugs became contaminated with viruses at manufacturing plants. These were all discovered before the drugs reached patients, but many of the incidents led to costly cleanups and in one instance a drug shortage.
Those looking forward to a day when science's Grand Unifying Theory of Everything could be worn on a t-shirt may have to wait a little longer as astrophysicists continue to find hints that one of the cosmological constants is not so constant after all.
In a paper published in prestigious journal Science Advances, scientists from UNSW Sydney reported that four new measurements of light emitted from a quasar 13 billion light years away reaffirm past studies that have measured tiny variations in the fine structure constant.
The cloud water path of mature tropical cyclones can be estimated by a notable sigmoid function of near-surface rain rate, according to Prof. Yunfei Fu, a professor at the School of Earth and Space Sciences, University of Science and Technology of China, and one of the authors of a recently published study in Advances in Atmospheric Sciences.
An international team of scientists that includes researchers from ITMO University has developed a new composite material based on perovskite nanocrystals for the purpose of creating miniature light sources with improved output capacity.
New research from the University of British Columbia and North Carolina State University could help scientists track how climate change is impacting the birds and the bees... of honey bees.
Heat can kill sperm cells across the animal kingdom, yet there are few ways to monitor the impact of heat on pollinators like honey bees, who are vital to ecosystems and agriculture around the world.
Researchers have demonstrated the world's first metasurface laser that produces "super-chiral light": light with ultra-high angular momentum. The light from this laser can be used as a type of "optical spanner" to or for encoding information in optical communications.
Chestnut Hill, Mass. (4/27/2020) - Humans differ from other primates in the types and amounts of care that males provide for their offspring. The precise timing of the emergence of human "fatherhood" is unknown, but a new theory proposes that it emerged from a need for partnership in response to changing ecological conditions, U.S. and French researchers report today in the Proceedings of the National Academy of Sciences.
