In evolutionary biology, the 'Life History Theory,' first proposed in the 1950s, postulates that when the environment is favorable, the resources used by any organism are devoted for growth and reproduction.

A dogma-challenging discovery reveals that highly adapted bacterial communities in the sinuses of people with cystic fibrosis become more fragmented and experience mutations that erode their genomes. So rather than targeting red herring mutations, researchers suggest paying attention to patterns of genomic adaptation versus erosion, which might better indicate a viable path towards the more effective therapeutics for cystic fibrosis. from Top Health News -- ScienceDaily https://ift.tt/3GbUx2i via IFTTT

Identifying the dynamic events occurring during urinary tract infections (UTI) has revealed a new potential strategy to combat this condition, considered the most common type of infection. from Top Health News -- ScienceDaily https://ift.tt/2ZompQa via IFTTT

While most of the COVID-19 vaccines are designed as a two-dose regimen, some countries have prioritized vaccinating as many people as possible with a single dose before giving out an additional dose. In a new study, researchers illustrate the conditions under which a "prime first" vaccine campaign is most effective at stopping the spread of the COVID-19 virus. The team found the vaccine waning rate to be a critically important factor in the decision. from Top Health News -- ScienceDaily https://ift.tt/3nhWn9i via IFTTT

Researchers examine the dynamics of social distancing practices, common defense against the spread of COVID-19, through the lens of particle-based flow simulations. The study models social distance as the distance at which particles, representing pedestrians, repel fellow particles and sheds light on the relationship between social distancing and pedestrian flow dynamics in corridors by illustrating how adherence to social distancing protocols affects two-way pedestrian movement in a shared space. from Top Health News -- ScienceDaily https://ift.tt/3G9Vrwh via IFTTT

Nonpharmaceutical interventions, such as isolation, quarantines, and lockdowns, have been implemented in an effort to contain the pandemic, but these are often disruptive and costly. In a new article, researchers identify new and sustainable interventions to contain outbreaks while minimizing the economic and social costs. They built a data-driven mobility model to simulate COVID-19 spreading in Hong Kong, by combining synthetic population, human behavior patterns, and a viral transmission model, and found that by controlling a small percentage of grids, the virus could be largely contained. from Top Health News -- ScienceDaily https://ift.tt/2Zi2p1L via IFTTT

Scientists argue that efforts to understand human cognition should expand beyond the study of individual brains. They call on neuroscientists to incorporate evidence from social science disciplines to better understand how people think. from Top Health News -- ScienceDaily https://ift.tt/3netoDn via IFTTT

In social experiments, three monkeys sat around a rotary table and took turns offering food to one of the other two monkeys. Certain neurons in the brain responded to the actions of other monkeys in the group and influenced an animal's upcoming decisions to reciprocate or retaliate. from Top Health News -- ScienceDaily https://ift.tt/3m2I1KA via IFTTT

Neuroscientists used wireless devices to record the neural activity of freely interacting Egyptian fruit bats, providing researchers with the first glimpse into how the brains of social mammals process complex group interactions. from Top Health News -- ScienceDaily https://ift.tt/2ZdFjcl via IFTTT

Researchers present what could be a much-needed helping hand to fight the COVID-19 virus. The study shows that analysis of a particular protein on the cell surface is likely to predict who is in danger of a serious infection caused by the virus. from Top Health News -- ScienceDaily https://ift.tt/3GaO33F via IFTTT

Researchers fabricate gold nanoparticles with a rapidly decaying radioisotope that can be internalized by cancer cells. Because the radiation remains strongly localized, high doses can be administered without concern for side effects. This research may lead to safer and more effective treatments for many types of cancer. from Top Health News -- ScienceDaily https://ift.tt/3aXDJ0y via IFTTT

Disinfectants and surgical smoke -- the gaseous by-product produced by heat-generating surgical instruments -- are among the hazardous chemicals to which physicians, nurses, and other hospital staff are exposed in operating rooms (OR) during electrosurgery and laser procedures. Long-time exposure to these chemicals in the OR may significantly increase one's risk of developing chronic obstructive pulmonary disease (COPD), according to a new study. from Top Health News -- ScienceDaily https://ift.tt/2Zij4lR via IFTTT

A scientist led a study that revealed how cells from the eye migrate deep into the brain to a processing core during brain development. These cells and their connections help regulate critical survival instincts in rodents. The findings help decode how these complicated brain circuits form, laying a potential foundation for future research into how these pathways may be coaxed to regenerate. from Top Health News -- ScienceDaily https://ift.tt/2Zf8TOU via IFTTT
