The health of women aged 65 and over appears to be related, in addition to their own socioeconomic characteristics, with that of their partners, as a result of traditional gender norms. This is one of the main conclusions of research led by Jordi Gumà, a researcher at the UPF Department of Political and Social Sciences, conducted in conjunction with Jeroen Spijker, a Ramon y Cajal I3 researcher at the Centre for Demographic Studies of the Autonomous University of Barcelona (CED-UAB), focusing on the case of Spain.
An international team of scientists from the University of Turku, Finland and PennState University, USA have solved a long-standing mystery of how living organisms distinguish RNA and DNA building blocks during gene expression paving the way for the design of new antiviral drugs. The new insights were published in the journal Nature Communications.
A single-celled alga undergoes genome surgery to remove non-essential parts. This can lead to a most efficient cellular factory for producing sustainable biofuels from sunlight and carbon dioxide.
Researchers from the Qingdao Institute of BioEnergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) have stripped hundred-kilobase genome from a type of oil-producing microalgae, knocking out genes non-essential for it to function. By doing so, they have created a "genome scalpel" that can trim microalgal genomes rapidly and creatively.
TROY, N.Y. -- Numeric anchoring is a long-established technique of marketing communication. Once a price is mentioned, that number serves as the basis for -- or "anchors" -- all future discussions and decisions. But new research shows that this phenomenon is not limited to decisions that involve numbers, the use and understanding of which require high-level cognitive thinking. Anchoring also biases judgments at relatively low levels of cognition when no numbers are involved.
In researching the causes and potential treatments for degenerative conditions such as Alzheimer's or Parkinson's disease, neuroscientists frequently struggle to accurately identify cells needed to understand brain activity that gives rise to behavior changes such as declining memory or impaired balance and tremors.
The critically endangered regent honeyeater is losing its "song culture" due to the bird's rapidly declining population, according to new research from The Australian National University (ANU).
Just like humans learning to speak, many birds learn to sing by associating with older birds of the same species. They risk losing this skill if adults become too rare. And if they don't learn to sing a sexy enough song, their chances of mating are reduced.
The UK variant of SARS-CoV-2 spread rapidly in care homes in England in November and December last year, broadly reflecting its spread in the general population, according to a study by UCL researchers.
Lightning strikes were just as important as meteorites in creating the perfect conditions for life to emerge on Earth, geologists say.
Minerals delivered to Earth in meteorites more than 4 billion years ago have long been advocated as key ingredients for the development of life on our planet.
Scientists believed minimal amounts of these minerals were also brought to early Earth through billions of lightning strikes.
Nanozymes, a group of inorganic catalysis-efficient particles, have been proposed as promising antimicrobials against bacteria. They are efficient in killing bacteria, thanks to their production of reactive oxygen species (ROS).
Despite this advantage, nanozymes are generally toxic to both bacteria and mammalian cells, that is, they are also toxic to our own cells. This is mainly because of the intrinsic inability of ROS to distinguish bacteria from mammalian cells.
The bacterial equivalent of a traffic jam causes multilayered biofilms to form in the presence of antibiotics, shows a study published today in eLife.
The study reveals how the collective behaviour of bacterial colonies may contribute to the emergence of antibiotic resistance. These insights could pave the way to new approaches for treating bacterial infections that help thwart the emergence of resistance.
Philadelphia, March 16, 2021 - A significant proportion of hospitalized patients with influenza develop complications of acute respiratory distress syndrome, driven by virus-induced cytopathic effects as well as exaggerated host immune response. Reporting in The American Journal of Pathology, published by Elsevier, investigators have found that treatment with an immune receptor blocker in combination with an antiviral agent markedly improves survival of mice infected with lethal influenza and reduces lung pathology in swine-influenza-infected piglets.
WASHINGTON -- Researchers have developed a new intravascular imaging technique that could one day be used to detect coronary plaques that are likely to lead to a heart attack. Heart attacks are often triggered when an unstable plaque ruptures and then blocks a major artery that carries blood and oxygen to the heart.
Machine learning can be used to comb through online reviews of substance use treatment facilities to home in on qualities that are important to patients but remain hard to capture via formal means, such as surveys, researchers from the Perelman School of Medicine at the University of Pennsylvania show. The researchers found that professionalism and staff dedication to patients were two of the top qualities that could be attributed to either a negative or positive review of the facility. Findings from this study were published today in the Journal of General Internal Medicine.
FLAGSTAFF, Ariz. -- March 16, 2021 -- The findings of a recent analysis conducted by the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest that ecosystems suitable for harboring ticks that carry debilitating Lyme disease could be more widespread than previously thought in California, Oregon and Washington.
