Lee Rannals for redOrbit.com – Your Universe Online Scientists have developed an equation that is able to estimate an individual's speed based on their footprints. Two Spanish scientists, writing in the journal Ichnos, said they used data from professional athletes and walking and running experiments in order to develop the equation. The team asked 14 paleontology students from the Complutense University of Madrid to run along a beach in Asturias. The scientists wanted to check...
[ Watch the Video: What is Bacteria? ] Alan McStravick for redOrbit.com - Your Universe Online In 2010, a NASA DC-8 soared high up into the troposphere to collect air samples in order to study air masses associated with tropical storms. What they found was quite surprising. Bugs - microorganisms actually - in the troposphere. The troposphere is the portion of the Earth’s atmosphere that extends from ground level up to approximately 12 miles above sea level, and apparently it is...
Alan McStravick for redOrbit.com - Your Universe Online Though their actions look suspiciously like play, a new study performed by University of California at Berkeley psychology professor and affiliate professor of philosophy Alison Gopnik shows that children approach problems in need of solutions in much the same manner as scientists. Her findings are published in today’s issue of the journal Science. By utilizing more precise advanced research methods and mathematical models that...
Researchers at Carlos III University of Madrid and the University of Zaragoza theoretically predict, in a scientific study, that contact networks have no influence on cooperation among individuals. For the past twenty years, there has been a great controversy regarding whether the structure of interactions among individuals (that is, if the existence of a certain contact network or social network) helps to foment cooperation among them in situations in which not cooperating brings benefits...
A total of 1,303 high school students in Aragon have participated in an online scientific-social experiment to determine the problems and conflicts arising from cooperation in present day society. This experiment, organized by the Instituto Biocomputación y Física de Sistemas Complejos (The Institute for Biocomputation and Physics of Complex Systems) (BIFI) at the Universidad de Zaragoza, together with the Fundación Ibercivis and Universidad Carlos III de Madrid (UC3M), is the largest one...
A situation where a majority of people cooperate never happens. This is due to the fact that a significant number of individuals never cooperate and if they do it is in response to the decision of their neighbors to cooperate or not, or a result of their mood at the time, according to an experimental study by researchers at Universidad Carlos III de Madrid (UC3M).The objective of this research is to understand how cooperation works in nature in general, and among humans in particular....
Research conducted in a computerized microworld by scientists at Arizona State University and Indiana University, including Nobel laureate Elinor Ostrom, show how common-pool resources "“ such as fisheries, forests, water systems or even bandwidth "“ can be managed effectively by self-organized user groups under certain conditions.The findings are published April 30 in the journal Science."We use different experiments with specially designed computer simulation games that include...
For decades, the traditional practice in animal testing has been standardization, but a study involving Purdue University has shown that adding as few as two controlled environmental variables to preclinical mice tests can greatly reduce costly false positives, the number of animals needed for testing and the cost of pharmaceutical trials.Joseph Garner, a Purdue assistant professor of animal sciences, said the finding challenges the assumption in drug discovery and related fields that animal...
Experiments based on recommendations from National Research Council BEAVERTON, Ore., May 27 /PRNewswire-USNewswire/ -- Helping students in high school and college think critically about chemistry experiments, while providing educators with easy-to-use labs, was the goal of authors Donald L. Volz and Ray Smola in Vernier Software & Technology's new 'Investigating Chemistry through Inquiry' lab book. The book takes a unique approach by providing direction for both open inquiry and guided...
The recent discovery of ageing vials of chemicals in a California lab contain surviving samples from the legendary experiments performed by chemist Stanley Miller in the 1950s.Many believe the samples provide evidence that life may have born violently, in erupting volcanoes in the midst of a thunderstorm.At age 22, Miller was studying for his PhD when he carried out his original, groundbreaking experiments (under his University of Chicago mentor, Harold Urey).By striking electric sparks in a...
