BINGHAMTON, NY -- A new leader takes office and foreign rivals begin to test the waters. How tough is this new leader? Are they willing to risk war, or just full of bluster?
This testing can escalate crises, increasing the risk of war as international adversaries gauge the new leader's willingness to use force. A new paper co-written by faculty at Binghamton University, State University of New York shows that when this "turnover trap" occurs depends a good deal on the politics back home, and the nature of the leader's transition into office.
AURORA, Colo. (Jan. 13, 2021) - Mucus in the lungs can be fatal for asthma patients, but scientists at the University of Colorado Anschutz Medical Campus have broken up those secretions at the molecular level and reversed their often deadly impacts.
In a study published Monday in the journal Nature Communications, the researchers explained how they created an inhaled treatment that disrupted the production of excess mucus by reducing disulfide bonds in mice and opening up their airways. The same treatment had similar impacts on human mucus samples.
A common bacterial species naturally infecting mosquitoes may actually be protecting them against specific mosquito pesticides, a study has found.
Wolbachia - a bacterium that occurs naturally and spreads between insects - has become more frequently used in recent years as a means of controlling mosquito populations.
Researchers at Linköping University, Sweden, have developed efficient blue light-emitting diodes based on halide perovskites. "We are very excited about this breakthrough", says Feng Gao, professor at Linköping University. The new LEDs may open the way to cheap and energy-efficient illumination.
The levels of small molecules called microRNAs (miRNAs) circulating in blood could help identify early on children with life-threatening forms of malaria, according to a study led by the Barcelona Institute for Global Health, an institution supported by "la Caixa" Foundation, in collaboration with the Manhiça Health Research Center (CISM) in Mozambique. The results, published in Emerging Infectious Diseases journal, could also help better understand the mechanisms underlying severe malaria.
Researchers from the University of Seville and the University of Pavia have identified a link between Amyotrophic Lateral Sclerosis (ALS) and the accumulation of DNA-RNA hybrids in the genome. The accumulation of these hybrids causes increased genomic damage and boosts genetic instability. This finding will make it possible to better understand the molecular basis of the disease, as well as to propose new solutions to curb it.
With ever-worsening climate change, there is a growing need for technologies that can capture and use up the atmospheric CO2 (carbon dioxide) and reduce our carbon footprint. Within the realm of renewable energy, CO2-based e-fuels have emerged as a promising technology that attempts to convert atmospheric CO2 into clean fuels. The process involves production of synthetic gas or syngas (a mixture of hydrogen and carbon monoxide (CO)). With the help of the reverse water-gas shift (RWGS) reaction, CO2 is broken down into the CO necessary for syngas.
Workaholism or work addiction risk is a growing public health concern that can lead to many negative mental and physical health outcomes such as depression, anxiety or sleep disorder. Perception of work (job demands and job control) may become a major cause of employees' work addiction. The international group of researchers including the HSE University scientist explored the link between work addiction risk and health-related outcomes using the framework of Job Demand Control Model.
A remarkable prediction of Einstein's theory of general relativity--the theory that connects space, time, and gravity--is that rotating black holes have enormous amounts of energy available to be tapped.
Thousands of genetic markers have already been robustly associated with complex human traits, such as Alzheimer's disease, cancer, obesity, or height. To discover these associations, researchers need to compare the genomes of many individuals at millions of genetic locations or markers, and therefore require cost-effective genotyping technologies. A new statistical method, developed by Olivier Delaneau's group at the SIB Swiss Institute of Bioinformatics and the University of Lausanne (UNIL), offers game-changing possibilities.
Researchers at Brazil's National Space Research Institute (INPE), in partnership with colleagues in the United States, United Kingdom and South Africa, have recorded for the first time the formation and branching of luminous structures by lightning strikes.
Analyzing images captured by a super slow motion camera, they discovered why lightning strikes bifurcate and sometimes then form luminous structures interpreted by the human eye as flickers.
Spatial isolation is known to promote speciation - but researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have now shown that, at least in yeast, the opposite is also true. New ecological variants can also evolve within thoroughly mixed populations.
WHAT:
Salmonella enterica serovar Typhimurium bacteria (S. Typhimurium) commonly cause human gastroenteritis, inflammation of the lining of the intestines. The bacteria live inside the gut and can infect the epithelial cells that line its surface. Many studies have shown that Salmonella use a "run-and-tumble" method of short swimming periods (runs) punctuated by tumbles when they randomly change direction, but how they move within the gut is not well understood.
As anxious passengers are often reassured, commercial aircrafts can easily continue to fly even if one of the engines stops working. But for drones with four propellers - also known as quadcopters - the failure of one motor is a bigger problem. With only three rotors working, the drone loses stability and inevitably crashes unless an emergency control strategy sets in.
A recent Point of Reference article, "The meat of the matter: Environmental dissemination of beef cattle agrochemicals," published in Environmental Toxicology and Chemistry, points at synthetic chemical cocktails being emitted from cattle feed yards into the environment and how they can impact our ecosystem and our health.
