Soldiers and Families Can Suffer Negative Effects from Modern Communication Technologies, Says MU Researcher

COLUMBIA, Mo. – As recently as the Vietnam and Korean wars, soldiers’ families commonly had to wait months to receive word from family members on the front lines. Now, cell phones and the internet allow deployed soldiers and their families to communicate instantly. However, along with the benefits of keeping in touch, using new communication technologies can have negative consequences for both soldiers and their families, according to a study by University of Missouri researcher Brian Houston. This research could lead to guidelines for how active military personnel and their families can best use modern communications.

“Deployed soldiers and their families should be aware that newer methods of communication, especially texting, can have unintended impacts,” said Houston, assistant professor of communication in the College of Arts and Science. “The brevity and other limitations of text messages often limit the emotional content of a message. The limited emotional cues in text messages or email increases the potential for misunderstandings and hurt feelings. For example, children may interpret a deployed parent’s brief, terse text message negatively, when the nature of the message may have been primarily the result of the medium or the situation.” (more…)

Astronomers Test Einstein in a New Regime Using Pair of Burnt-Out Stars

AUSTIN, Texas — A team of astronomers led by researchers from The University of Texas at Austin has confirmed the emission of gravitational waves from the second-strongest known source in our galaxy by studying the shrinking orbital period of a unique pair of burnt-out stars. Their observations tested Albert Einstein’s theory of general relativity in a new regime. The results will be published soon in The Astrophysical Journal Letters.

Last year, the same team discovered that the two white dwarf stars are so close together that they make a complete orbit in less than 13 minutes, and they should be gradually slipping closer. The system, called SDSS J065133.338+284423.37 (J0651 for short), contains two white dwarf stars, which are the remnant cores of stars like our sun. (more…)

Why “Scientific Consensus” Fails to Persuade

Suppose a close friend who is trying to figure out the facts about climate change asks whether you think a scientist who has written a book on the topic is a knowledgeable and trustworthy expert. You see from the dust jacket that the author received a Ph.D. in a pertinent field from a major university, is on the faculty at another one, and is a member of the National Academy of Sciences. Would you advise your friend that the scientist seems like an “expert”?   (more…)
