Scientific research using studies and analyses

Studies and analyses are vital to progress and innovation and are the only way to empirically verify theories.

Science and empirical studies and analyses

Not all fields of science are dependent on empirical studies and analyses to verify a thesis. Mathematics, theology, philosophy and law are examples of fields that revolve within a stand-alone world in which new findings are derived by means of logical operations consisting of axioms, postulates or articles of faith (theology) that need not be proven true or accurate through empirical studies or analyses. Although these subjects are indispensable when it comes to basic research, by themselves they don't yield technical advances.

Empirical scientific approaches are diametrically opposed to these fields however. In this case, new theories are developed based on thought processes, observations and speculation. Ensuring that this knowledge has actual scientific relevance requires that it undergo an empirical evaluation however. Researchers rely on studies and analyses to compare these theses with real observations. New scientific knowledge is considered valid only after empirical studies and analyses show that theory and reality coincide. In the process it is imperative that the studies and analyses always produce the same result under the same experiment structure. Only then it is empirically proven that the result actually behaves in line with the theory.

Using empirical studies and analyses beyond the natural sciences and engineering

The validation process for new findings based on studies and analyses as described above is in no way limited to natural and engineering sciences such as physics, biology, chemistry, medicine and health, machine engineering or aero and space engineering. In fields such as the social sciences, studies and analyses are also indispensable for empirically proving the accuracy of assumptions and conclusions. Sociology uses empirical-based statistics, studies and analyses to determine if statements about the migration behavior of specific population groups is accurate for instance. The field of psychology also relies on analyses and studies to empirically validate the assumptions of certain behavior patterns.

Progress and innovation through empirical studies and analyses

Before the Enlightenment changed our way of thinking, universities tended to postulate and speculate more than perform scientific research. Innovations therefore were apt be accidental. Once researchers were convinced that scientific results were only possible through the use of empirical studies and analysis, the groundwork was laid for the rapid advances in science that followed. Empirical studies and analyses range from simple experiments, particularly by measuring, weighing and counting, to extremely complex processes that require an enormous amount of time and money. Determining the validity of scientific theories using empirical assurances is one of the prerequisites for implementing these theories in practice. When a specific fact has been confirmed and documented based on studies and analyses, the assumption is that it will remain a fact in the future under the same premises. Only then does it make sense to develop new technologies based on this knowledge, because this provides sufficient proof of the assumption that they always function in the same manner.

Two historical examples of progress based on studies and analyses

Gregor Mendel's studies and analyses on genetics provided empirical proof of his theories of heredity, which then led to modern plant breeding and the establishment of food security for millions of people. The effectiveness of penicillin, another invaluable innovation for mankind, was empirically proven by Alexander Fleming through medical studies and analyses.

Screening questions fail to identify teens at risk for hearing loss

Subjective screening questions do not reliably identify teenagers who are at risk for hearing loss, according to researchers at Penn State College of Medicine. The results suggest that objective hearing tests should be refined for this age group to replace screening questions.

The American Academy of Pediatrics, in partnership with the Bright Futures children's health organization, sets standards for pediatric preventive care. The...

Can Bariatric Surgery Lead to Severe Headache?

Bariatric surgery may be a risk factor for a condition that causes severe headaches, according to a study published in the October 22, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.

In the study, gastric bypass surgery and gastric banding surgery were associated with later developing a condition called spontaneous intracranial hypotension...

Even depressed people believe that life gets better

Adults typically believe that life gets better — today is better than yesterday was and tomorrow will be even better than today. A new study shows that even depressed individuals believe in a brighter future, but this optimistic belief may not lead to better outcomes. The findings are published in Clinical Psychological Science, a journal of the Association for Psychological Science.

The research shows that middle-aged adults who had a history of depression tended to evaluate their past and current lives in more negative terms than did...

School and job failure may increase drug users' risks of suffering a fatal overdose

For the first time, researchers have found that problem drug users with less successful educational and employment careers are more likely to die of an overdose. Moreover, there is no link between parents' professional status and the likelihood that their problem drug-using child will die from an overdose.

“Overdose victims are roughly twice as likely to have failed to finish secondary school successfully and one-and-a-half times more likely to be unemployed than...

Change your walking style, change your mood

Our mood can affect how we walk — slump-shouldered if we're sad, bouncing along if we're happy. Now researchers have shown it works the other way too — making people imitate a happy or sad way of walking actually affects their mood.

Subjects who were prompted to walk in a more depressed style, with less arm movement and their shoulders rolled forward, experienced worse moods than those who...

Teens' science interest linked with knowledge, but only in wealthier nations

It seems logical that a student who is interested in science as an academic subject would also know a lot about science, but new findings show that this link depends on the overall wealth of the country that the teen calls home. The research suggests that individual science achievement may be influenced as much by broad national-level resources as it is by personal interest and motivation.

This is a photo of students in a chemistry class."Our results suggest that children with high levels of interest in science are able to turn their scientific...

More Physical Activity Improved School Performance

Just two hours of extra physical activity each week can improve school performance. This has been shown by a study of approximately 2,000 twelve-year-olds carried out by scientists at the Sahlgrenska Academy, University of Gothenburg.

The scientists Lina Bunketorp Käll, Michael Nilsson and Thomas Linden, at the Centre for Brain Repair and Rehabilitation at the Sahlgrenska Academy, University...

Study sheds light on factors that may contribute to pancreatic cancer

New research that provides a better understanding of pancreatic cancer may help identify individuals at increased risk. The findings are published early online in Cancer, a peer-reviewed journal of the American Cancer Society.

Pancreatic cancer is a stealthy cancer that is usually detected at very late stages and has a 5-year survival rate of less than 5 percent. Strategies that...

'Data smashing' could unshackle automated discovery

A little known secret in data mining is that simply feeding raw data into a data analysis algorithm is unlikely to produce meaningful results, say the authors of a new Cornell University study.

From recognizing speech to identifying unusual stars, new discoveries often begin with comparison of data streams to find connections and spot outliers.
