Orlando, Fla - Though it's difficult to think about, what we would do in the event of a violent attack has probably crossed most of our minds, especially as the number and scope of these tragic events has risen in recent years. While we hope it's a situation we will never encounter, being prepared to help victims in the wake of tragedy can be extremely powerful.
The brain plays a major role in controlling our blood glucose levels. In type 2 diabetics this glucose metabolism brain control is often dysfunctional. Genetic components for this phenomenon have so far remained elusive. A group of scientists at Helmholtz Zentrum München and the German Center for Diabetes Research (DZD) have now shown in the Journal of Clinical Investigations that in men a genetic variant of the gene DUSP8 can increase the risk for type 2 diabetes by impairing our brain response to the hormone insulin.
Hokkaido University scientists have shown that Interleukin-34 is a prognostic marker and drug target for Triple Negative Breast Cancer.
A viscous biopaste that is easy to process, solidifies quickly and is suitable for producing even complex structures using the 3D printing process has been developed by a research team headed by Prof. Dr. Marie-Pierre Laborie from the Chair of Forest Biomaterials at the University of Freiburg. The wood-based biodegradable synthetic could potentially be used in lightweight construction, amongst other things. The scientists have published their initial results in the journals Applied Bio Materials and Biomacromolecules.
If and how babies recall what they have learned depends on their mood: what they've learned when feeling calm is inaccessible when they're acitive and vice versa. This was shown in a study conducted by developmental psychologists at Ruhr-Universität Bochum (RUB) with 96 children aged nine months. They published their report in the journal Child Development from 19. August 2020.

Information security has drawn considerable attention as the exponential growth of information communication in the era of big data. The stimuli-responsive photoluminescent materials that can quickly switch among different states have been an effective approach to increasing the data security and storage density of such devices.
Electricity and magnetism have been unified by Maxwell's equations, which is the foundation of a vast amount of modern technologies. Nevertheless, achieving efficient coupling of electric and magnetic properties in solid materials has always been challenging throughout the century. This mainly results from that the magnetic and electric properties originate from, respectively, the spin and orbital dynamics of the electron.
A tunnel junction is a device consisting of two conducting layers separated by an insulating layer. Classically, the resistance for driving current across an insulating layer is infinite; however, when the insulating layer is thin (~ 1-2 nanometers), charge carriers may tunnel through the insulating layer, due to their quantum nature. When the conducting layers are magnetic, a magnetic tunnel junction (MTJ), whose resistance depends on the magnetic configurations, is obtained.
Interlocked molecular species have received considerable attention recently, not only because of their intriguing structures and topological importance, but also because of their important applications as molecular machines and nanoscale devices. Benefiting from the reversible coordination bond, some complicated interlocked structure could be realized by high-yield, one-step processes, for example, [2]catenanes and Solomon knot.
Electro-optic crystal shows great promise for extensive applications in laser, optoelectronics, and optical communication, such as high-speed E-O switch, modulator, deflector, laser mode-locking, photoetching, laser radar (LIDAR) and so on. With the prosperous development of Terahertz (THz) spectroscopy technique, E-O crystals are employed in this realm for generation and detection of the THz electromagnetic radiation.
Creeped out by cooties? Grossed out by germs? Squeamish about sickness?
If so, then you might also find yourself engaging in more preventative health behaviors, like frequent handwashing and disinfecting your living environment, during the ongoing coronavirus pandemic.
More than other factors, strong feelings of germ aversion and pathogen disgust are significantly associated with concern about COVID-19 and preventative behavior, according to findings from UConn School of Nursing researchers published in the journal PLOS ONE.
Selective communication among different brain regions is crucial for brain function. But the weak and sparse connectivity of the brain is a big hurdle. During the last decade neuroscientists have identified various means by which this limitation can be counteracted. Now scientists from Iran, Germany and Sweden have identified a new role of bi-directional connections in accelerating the communication between brain regions. They have now presented their results in the scientific journal PLoS Computational Biology.
A joint project led by Kumamoto University (Japan) has discovered a new mechanism for anticancer drug resistance in gastric cancer. Researchers found that the Annexin A6 molecule contained in extracellular vesicles (EVs) is secreted by cancer-associated fibroblasts (CAFs) and taken up by gastric cancer cells, resulting in resistance to anticancer drug treatments. This finding creates new avenues for novel drug development targeting Annexin A6 and cancer-associated fibroblasts (CAFs).
NASA's Terra satellite gathered infrared data on Tropical Depression 14 as it moves through the Caribbean Sea. Infrared data was used to find the location of the strongest storms.
NASA's Terra satellite uses infrared light to analyze the strength of storms by providing temperature information about the system's clouds. The strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.
There are more than 70 species of flavivirus, and many cause diseases in humans and animals, including dengue, Zika and yellow fever viruses. A novel flavivirus identification test that is both fast and sensitive has been validated in Brazil by Mariana Sequetin Cunha and collaborators at the Adolfo Lutz Institute, a leading epidemiological surveillance laboratory that reports to the São Paulo state government.
