Tsukuba, Japan - Tomatoes are one of the most popular types of fresh produce consumed worldwide, as well as being an important ingredient in many manufactured foods.
As with other cultivated crops, some potentially useful genes that were present in its South American ancestors were lost during domestication and breeding of the modern tomato, Solanum lycopersicum var. lycopersicum.
Multi-disciplinary researchers at The University of Manchester have helped develop a powerful physics-based tool to map the pace of language development and human innovation over thousands of years - even stretching into pre-history before records were kept.
(Scottsdale, Ariz. - January 27, 2021) HIRREM (the legacy research technology of Cereset - a Brain State Company) was utilized by the Wake Forest School of Medicine to study symptoms of traumatic stress in military personnel before and after use of Cereset (legacy) intervention.
A new paper from UC Santa Cruz researchers, published in Proceedings of the National Academy of Sciences, shows that fear of humans causes mountain lions to increase their energy expenditures as they move through the landscape, and this can ultimately limit the size of the home ranges they're able to maintain.
There are an estimated 40,000 to 50,000 species of micro-organism per gram of soil. Addition of certain microbes can tailor soil characteristics: removing contaminants, improving fertility and even making barren land available for farming.
The Microbiology Society's report calls for increased access to research into soil health, promoting outreach activities in agricultural colleges and schools and showcasing work in non-academic outlets. This, say microbiologists, is the best way to collaborate with farmers to improve soil health and agricultural productivity.
Children determine emotion by what they hear, rather than what they see, according to new research.
The first-of-its-kind study, by Durham University's Department of Psychology, looked at how children pick up on the emotions of a situation.
They found that whilst adults prioritised what they see, young children showed an auditory dominance and overwhelmingly prioritised what they could hear.
The scientific process is an iterative and collaborative journey. Research is published, others can weigh in on results, and hypotheses can be corroborated, refuted, or further refined and tested. Though it may seem like second guessing or perhaps become contentious in some cases, this often overlooked aspect of the scientific method makes science better by continuing to challenge scientific assertions, thereby expanding and deepening our understanding.
Hydrogen is an important factor in a sustainable energy system. The gas stores energy in chemical form and can be used in many ways: as a fuel, a feedstock for other fuels and chemicals or even to generate electricity in fuel cells. One solution to produce hydrogen in a climate-neutral way is the electrochemical splitting of water with the help of sunlight. This requires photoelectrodes that provide a photovoltage and photocurrent when exposed to light and at the same time do not corrode in water. Metal oxide compounds have promising prerequisites for this.
In a study of 500 sourdough starters spanning four continents, scientists have garnered new insights into the environmental factors that contribute to each sourdough starter's microbial ecosystem, and how different types of microbes influence both a sourdough's aroma and how quickly the sourdough rises. The results may surprise sourdough enthusiasts.
Manipulating individual electrons with the goal of employing quantum effects offers new possibilities and greater precision in electronics. However, these single-electron circuits are governed by the laws of quantum mechanics, meaning that deviations from error-free operation still occur - albeit (in the best possible scenario) only very rarely. Thus, insights into both the physical origin the and metrological aspects of this fundamental uncertainty are crucial for the further development of quantum circuitry.
Every year, more than 400,000 people die from malaria, the majority are children under the age of five years old, who die from a disease which affects more than 200 million people a year.
The most serious form of the disease is cerebral malaria which may cause severe neurological consequences and, in the worst-case scenario, result in death. The precise mechanism behind cerebral malaria has remained a mystery - until now, says a research group from the Department of Immunology and Microbiology at the University of Copenhagen.
WASHINGTON -- A multi-institutional group of researchers has developed new metamaterial tiles that will help improve the sensitivity of telescopes being built at the preeminent Simons Observatory in Chile. The tiles have been incorporated into receivers that will be deployed at the observatory by 2022.
UNIVERSITY PARK, Pa. -- The actions that older adults take on Facebook may be more important to their user experience and well-being than their overall use of the site, according to researchers.
In a study conducted by a team that included researchers from Penn State, older adults experienced different levels of competence, relatedness and autonomy on Facebook based on the types of their activities on the site.
Heart disease is a killer threat for southern sea otters feasting on domoic acid in their food web, according to a study led by the University of California, Davis.
The study, published in the journal Harmful Algae, examined the relationship between long-term exposure to domoic acid and fatal heart disease in southern sea otters, a threatened marine mammal.
Skeletal muscle is the largest tissue in the human body and is responsible not only for locomotion but for energy metabolism and heat production. Age-related muscle atrophy reduces motor function and contributes to the need for nursing care. In addition, muscle atrophy associated with various chronic diseases is known to be a risk factor for life expectancy. Myoblasts, the progenitor cells of muscle, play an important role in maintaining muscle homeostasis.
