The sign of a healthy personal relationship is one that is equally mutual - where you get out just as much as you put in. Nature has its own version of a healthy relationship. Known as mutualisms, they are interactions between species that are mutually beneficial for each species. One example is the interaction between plants and pollinators, where your apple trees are pollinated and the honeybee gets nectar as a food reward. But what makes these mutualisms persist in nature?
INFORMS Journal Marketing Science New Study Key Takeaways:
"Word-of-mouth" is not always a substitute for advertising.
When consumers learn about products from other consumers, businesses should increase advertising spending to prove their product is high-quality.
When all consumers share their experiences, a high-quality business may be better served by reducing its advertising spending.
As more negative experiences are shared, it can be optimal for a high-quality business to spend more on advertising.
Just like humans, microbes have equipped themselves with tools to recognize and defend themselves against viral invaders. In a continual evolutionary battle between virus and host, CRISPR-Cas act as a major driving force of strain diversity in host-virus systems.
LIVERMORE, Calif. -- The development of a new method to make non-volatile computer memory may have unlocked a problem that has been holding back machine learning and has the potential to revolutionize technologies like voice recognition, image processing and autonomous driving.
For recreational fishing enthusiasts, the thrill of snagging their next catch comes with discovering what's hooked on the end of the line. In many freshwater streams and rivers -- across the central and eastern parts of the U.S. -- anglers are often catching a popular freshwater game fish: the smallmouth bass. Now, scientists have discovered a new level of biodiversity within that species.
Nearly every organism hosts a collection of symbiotic microbes--a microbiome. It is now recognized that microbiomes are major drivers of health in all animals, including humans, and that these symbiotic systems often exhibit strong daily rhythms.
More research is needed before a less invasive form of ventilation is used near the end of life for patients who have cancer and dementia, recommends the authors of a scientific paper published in JAMA Internal Medicine.
Sex, age, and severity of disease may be useful in identifying COVID-19 survivors who are likely to have high levels of antibodies that can protect against the disease, according to a new study co-led by researchers at Johns Hopkins Bloomberg School of Public Health.
COLLEGE PARK, Md. - Anxiety, the most common family of mental illnesses in the U.S., has been pushed to epic new heights by the COVID-19 pandemic, with the Centers for Disease Control and Prevention estimating that nearly 1 in 3 U.S. adults and a staggering 41% of people ages 18-29 experienced clinically significant anxiety symptoms in late August. Now, the findings of a recent UMD-led study indicate that some long-accepted thinking about the basic neuroscience of anxiety is wrong.
Talking to people at gun shows about suicide prevention and the risks of unsecured firearms can lead to safe weapons storage, according to a new study.
The research by Forefront Suicide Prevention at the University of Washington, from visits to 18 gun shows and other community events around Washington state last year, found that engaging people in a community-based setting, in an empathetic conversation focused on safety, resulted in more people locking up their firearms.
PULLMAN, Wash. - People with obsessive-compulsive disorder, or OCD, report that the severity of their symptoms was reduced by about half within four hours of smoking cannabis, according to a Washington State University study.
PITTSBURGH, Oct. 19, 2020 - Older people who report greater levels of social engagement have more robust gray matter in regions of the brain relevant in dementia, according to new research led by scientists at the University of Pittsburgh Graduate School of Public Health. It is the first to use a particularly sensitive type of brain imaging to conduct such an evaluation.
CHAMPAIGN, Ill. -- Researchers studied the effects of a 12-week exercise regimen on 148 active-duty Air Force airmen, half of whom also received a twice-daily nutrient beverage that included protein; the omega-3 fatty acid, DHA; lutein; phospholipids; vitamin D; B vitamins and other micronutrients; along with a muscle-promoting compound known as HMB. Both groups improved in physical and cognitive function, with added gains among those who regularly consumed the nutritional beverage, the team reports.
The findings appear in the journal Scientific Reports.
Transportation is the top source of greenhouse gas emissions in the United States, accounting for almost 30 percent of total emissions. In the national and global effort to reduce emissions and mitigate climate change, electric vehicles (EVs) provide an attractive option. But despite dropping prices and rising popularity, EVs continue to make up a small percentage of the automotive industry's market share.
Any Red Sea diver will have encountered colorful triggerfish along coral reefs, and some divers will have experienced the painful bite of their huge teeth if they get too close to their nesting grounds. Now, Ph.D. student Matthew Tietbohl and colleagues at KAUST report a peculiar feeding strategy by a titan triggerfish that highlights their innate ability to learn and adapt.
