The laboratory of the UMA "BacBio" has proved that Bacillus subtilis cells, when deprived of an amyloid protein (TasA), exhibit a range of cytological anomalies and dysfunctions leading to their premature death. A discovery that enables progress to be made in understanding the role of these proteins, widely distributed in the microbial world, and helps improve biological control methods in sustainable agriculture. This research has been recently published in the scientific journal Nature Communications.
S. maltophilia strains occur in several natural and human associated ecosystems. The bacterium was long regarded as relatively unproblematic but is now considered to be one of the most feared hospital pathogens, as it frequently causes infections and is resistant to a number of antibiotics. This can be particularly dangerous for immune-compromised patients or for patients with underlying inflammatory lung diseases such as cystic fibrosis.
Modern bioinformatics allows us to take a look into the past and find out when certain species diverged during evolution, which of them still are genetically close to each other, and which are not. An international team of researchers, which, among others, includes the academic supervisor of ITMO University's Laboratory of Genomic Diversity and researchers from the University of Copenhagen, Barcelona Institute of Science and Technology, and other research centers from all over the world, analyzed the genomes of extinct and living lions.
CHAMPAIGN, Ill. -- Corn cultivation spread from Mesoamerica to what is now the American Southwest by about 4000 B.C., but how and when the crop made it to other parts of North America is still a subject of debate. In a new study, scientists report that corn was not grown in the ancient metropolis of Cahokia until sometime between A.D. 900 and 1000, a relatively late date that corresponds to the start of the city's rapid expansion.
The findings are published in the journal American Antiquity.
For Army scientists, the goal of neuroscience research is pursuing the inner workings of the human brain to advance scientific understanding and improve Soldier performance.
Researchers recently applied new techniques to modify brain activity. Not only are these techniques used to characterize and study complex networks such as in telecommunications or social networks -- they describe how different nodes, or elements of the network: brain regions in neuroscience, or individuals in social networks, interact with each other.
HOUSTON - (May 14, 2020) - Early studies show evidence of COVID-19 genetic material in fecal matter, but more work is needed to determine if the virus can be spread through stool, according to a new review paper from a Rice University epidemiologist.
Some people with HIV need to undergo an allogeneic stem cell transplantation in order to treat different types of blood cancer. Most of the patient's immune cells are eliminated during these transplantations. Stem cells from a healthy donor are then used to replace the patient's damaged bone marrow and restore their immune system.
New Rochelle, NY, May 13, 2020--Artificial intelligence, machine learning, blockchain, and other key digital technology applications will play a vital role addressing the new healthcare challenges triggered by the COVID-19 pandemic, according to a peer-reviewed Special Issue of OMICS: A Journal of Integrative Biology.

A University of Missouri Health Care neurologist has published more than 40 new recommendations for evaluating and treating stroke patients based on international research examining the link between stroke and novel coronavirus (COVID-19).
Neurologist Adnan I. Qureshi, MD, a professor of clinical neurology at the MU School of Medicine, led a team of stroke experts from 18 countries with documented COVID-19 outbreaks to develop recommendations for doctors evaluating patients with acute ischemic stroke who have either suspected or confirmed COVID-19 infection.
TAMPA, Fla. -- Chimeric antigen receptor T-cell therapy, or CAR T, has become a game changer for lymphoma and leukemia patients who have relapsed or become resistant to previous treatments. The therapy uses a patient's own immune cells that are re-engineered in the lab to seek out and kill cancer cells when infused back into the patient. Yescarta® (axicabtagene ciloleucel) was the first CAR T-cell therapy approved for the treatment of adults with large B cell lymphoma.
From vast herds of wildebeest thundering across the Serengeti to a malaria-laden mosquito silently stalking a human host, the movement of animals has effects that reverberate throughout the biosphere. The way that animals move governs many ecological interactions including predation, disease transmission, and human-wildlife conflict. Encounter rates, which quantify how often moving individuals come in contact with each other, serve as the "glue" that links movement behavior to ecological processes.
MANHATTAN, KANSAS -- There are many unanswered questions about COVID-19. A Kansas State University infectious disease scientist and collaborators are offering a possible research road map to find the answers.
RESEARCH TRIANGLE PARK, N.C. -- Built with wheeled appendages that can be lifted, a new robot developed with U.S. Army funding has complex locomotion techniques robust enough to allow it to climb sand covered hills and avoid getting stuck. The robot has NASA interested for potential surveying of a planet or the Moon.
In a study published today in Current Biology, Arne Meyer, John O'Keefe and Jasper Poort used a lightweight eye-tracking system composed of miniature video cameras and motion sensors to record head and eye movements in mice without restricting movement or behaviour. Measurements were made while the animals performed naturalistic visual behaviours including social interactions with other mice and visual object tracking.
University of Alberta biologists have invented a new way for sequencing circular DNA, according to a new study. The tool--called CIDER-Seq--will give other scientists rich, accurate data on circular DNA in any type of cell.
