The World Institute of Kimchi (hereinafter "WiKim") (Acting Director Dr. Choi, Hak-Jong) announced that it had identified the origin source of lactic acid bacteria involved in the fermentation of kimchi and the characteristics of the fermentation process depending on the strains of lactic acid bacteria.
The information of the territory provided by the laser technology from an airplane can be combined with data collected in mountain lakes with an inflatable boat and a small echo sounder to obtain three-dimensional maps. The system has been successfully tested by two geologists at the Truchillas glacial lake in Spain.
Scientists studying mountain lakes, often located in remote areas that are difficult to access, are faced with the problem of climbing with heavy and costly equipment. Helicopters are often essential.
Thousands of cancer patients in the UK have had their treatment stopped or delayed because of COVID-19, and with pressures mounting on the health service, Cancer Research UK calls for widespread testing to prevent unnecessary cancer deaths.*
The global pandemic has caused enormous disruption to cancer services across the country including delays to cancer treatment, screening and diagnosis, and profound decreases in patients being urgently referred to hospital with suspected cancer symptoms.**
The sudden stop of capital flow of a country means, according to experts, a bottleneck to its foreign finance, that is to say, the bankruptcy of the country, as it leads to the contraction of international capital flows and the purchase and sale of foreign assets.
Bryophytes, phylogenetically placed between algae and pteridophytes, are divided into three classes, mosses, liverworts, and hornworts. Bryophytes are a source of traditional medicines throughout the world. Bryophyte phytochemistry is a fascinating research niche as some compounds - such as secondary metabolites - from these sources have been found to have bioactive properties. Liverworts and other bryophytes have yielded a rich array of secondary metabolites.
In 2019, the global population without access to electricity dipped below 1 billion for the first time. This progress has however been uneven, both across and within different regions. A new IIASA study shows that to ensure universal access to affordable, reliable, and modern electricity services by 2030 in sub-Saharan Africa, the pace of electrification must more than triple.
What effects do global warming and the formation of fine particles have on each other? Since the entire atmosphere cannot be heated for experimental purposes, a part of it is put in a chamber and investigated there. Now, a standard procedure has been drawn up for analysing fine particles in experimental chambers.
The number of children infected with the coronavirus is far more extensive than what is currently reported -- a hidden detail that could vastly underestimate the demand on health care systems and pediatric intensive care units (PICUs).
Diseases with a genetic cause could, in theory, be treated by supplying a correct version of the faulty gene. However, in practice, delivering new genetic material to human cells is difficult. A promising method for the delivery of such genes involves the use of DNA/lipid complexes (lipoplexes). Scientists at the University of Groningen have now used advanced simulations to investigate how these lipoplexes deliver DNA fragments into cells. The results, which were published in the journal eLife on 16 April, can be used to improve their efficiency.
LAWRENCE, KANSAS -- David Slusky keeps hearing the same comments from other parents who are isolating with young children.
"They're telling their kids, 'Please don't do gymnastics on the stairs because this is not the week I want to take you to the hospital!' Many of us are trying to both avoid getting COVID-19 and anything that might send us to the hospital," said Slusky, associate professor of economics at the University of Kansas.
He believes Americans have now been reminded how dangerous this situation is ... even without a pandemic exacerbating matters.
Scientists have understood quite well why so many poisonous or distasteful animals have brightly colored bodies - the colors send a message to the predators: "don't eat me, or you'll get sick and die." These permanent warning signals became textbook examples of "aposematism": use of conspicuous signals to warn predators. But not all animals show their warning colors all the time. Some toxic animals actually hide the warning colors, showing them only at the very last moment when they are about to be attacked (thus called "switchable aposematism").
For years, speculation about the poor quality of vital agricultural supplies in the African nation of Uganda has focused on questions of deliberate tampering with products - adding rocks to bags of seed in order to charge more money for the heavier product, for instance. But in a recent publication, two UConn researchers found no evidence of deliberate adulteration - but plenty of proof that mismanagement and inadequate infrastructure pose a significant problem for Ugandan farmers.
Washington, DC - April 17, 2020 - Genetic variability in the human immune system may affect susceptibility to, and severity of infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus disease (COVID-19). The research is published today, April 17 in the Journal of Virology, a publication of the American Society for Microbiology.
The genetic material--DNA-- of plants and animals (within the latter humans) is stored inside the cell, and DNA packing is guaranteed by proteins called histones. Furthermore, histones play a key role in regulating the activation of gene expression and its timing: a given stimulus modifies a histone, making it allow or repress the expression of a gene.
Two new species of viruses have been identified in blood samples taken from patients in Brazil's northern region who had similar symptoms to those of dengue or Zika, such as high fever, severe headache, rash and red skin spots. One belongs to the genus Ambidensovirus and was found in a sample collected in the state of Amapá. The other belongs to the genus Chapparvovirus and was found in blood from the state of Tocantins.
