Asthma patients reduce symptoms, improve lung function with shallow breaths, more CO2

Asthma patients taught to habitually resist the urge to take deep breaths when experiencing symptoms were rewarded with fewer symptoms and healthier lung function, according to a new study from the Department of Psycholgoy at Southern Methodist University.

The findings are from a large clinical trial funded with a grant from the National Institutes of Health’s National Heart, Lung, and Blood Institute. Continue reading

Study will teach algebra with student-authored stories that draw on their own interests

Can students learn algebra from Instagram and video games?

SMU teaching researcher Candace Walkington thinks so. Walkington’s new study, funded by the National Academy of Education, will test that idea.

Students will describe how linear relationships approximate what they encounter in their everyday lives, such as how they accumulate followers in Instagram or score points in a video game over time Continue reading

Hunt begins for elusive neutrino particle at one of the world’s largest, most powerful detectors

NOvA, SMU, Thomas Coan, Fermilab, neutrinosWhen scientists pour 3.0 million gallons of mineral oil into what are essentially 350,000 giant plastic tubes, the possibility of a leak can’t be overlooked, says SMU physicist Thomas E. Coan.

The oil and tubes are part of the integral structure of the world’s newest experiment to understand neutrinos — invisible fundamental particles so abundant they constantly bombard us and pass through us at a rate of more than 100,000 billion particles a second. Continue reading

Key to speed? Elite sprinters are unlike other athletes — deliver forceful punch to ground

Usain Bolt, elite sprinters, Weyand, punch, SMUThe world’s fastest sprinters have unique gait features that account for their ability to achieve fast speeds, according to two new studies from Southern Methodist University, Dallas.

The new findings indicate that the secret to elite sprinting speeds lies in the distinct limb dynamics sprinters use to elevate ground forces upon foot-ground impact. Continue reading

Scientists issue call to action for archaeological sites threatened by rising seas, urban development

Western%20Site%20Margin%20400x300.jpgShould global warming cause sea levels to rise as predicted in coming decades, thousands of archaeological sites in coastal areas around the world will be lost to erosion.

With no hope of saving all these sites, an SMU archaeologist and others call for scientists to assess the sites most at risk.
