At peak fertility, women who desire to maintain body attractiveness report they eat less

SMU, Meltzer, ovulation, weight loss, women, attractivenessBiology isn’t the only reason women eat less as they near ovulation, a time when they are at their peak fertility.

Three new independent studies found that another part of the equation is a woman’s desire to maintain her body’s attractiveness, says social psychologist and assistant professor Andrea L. Meltzer, Southern Methodist University, Dallas. Continue reading

SMU seismology team to cooperate with state, federal scientists in study of May 7 Venus, Texas earthquake

Injctn sign 400x300SMU’s seismology team was not surprised by the magnitude 4.0 earthquake that occurred near Venus, Texas, recently, having been aware of multiple smaller earthquakes identified nearby in recent months.

The team has recommended to state lawmakers a permanent regional network of monitors, supplemented by portable instruments, to deploy in a time-sensitive manner. Continue reading

1st proton collisions at the world’s largest science experiment expected to start the first or second week of June

Dallas Hall w scatterThe schedule announcement came during an international physics conference on the SMU campus from senior research scientist Albert De Roeck, a staff member at CERN and a leading scientist on one of the Large Hadron Collider‘s key experiments in Geneva.

“It will be about another six weeks to commission the machine, and many things can still happen on the way,” said De Roeck. The LHC in early April was restarted for its second three-year run after a two-year pause to upgrade the machine to operate at higher energies. At higher energy, physicists worldwide expect to see new discoveries about the laws that govern our natural universe. Continue reading

Most likely cause of 2013-14 earthquakes: Combination of gas field fluid injection, removal

Azle, earthquakes, fracking, injection, faults, SMU, Modelled pressureAn SMU-led seismology team finds that high volumes of wastewater injection combined with saltwater (brine) extraction from natural gas wells is the most likely cause of earthquakes occurring near Azle, Texas, from late 2013 through spring 2014.

The seismology team identified two intersecting faults, and developed a sophisticated 3D model to assess the changing fluid pressure within the rock formation. Continue reading

17 million-year-old whale fossil provides 1st exact date for East Africa’s puzzling uplift

Whale, fossil, kenya, Great Rift, Africa, Jacobs, WichuraUplift associated with East Africa’s Great Rift Valley and the environmental changes it produced have puzzled scientists for decades because the timing and starting elevation have been poorly constrained.

Now paleontologists have tapped a fossil from the most precisely dated beaked whale in the world — and the only stranded whale ever found so far inland on the African continent — to pinpoint a date when the mysterious elevation began. Continue reading

SMU analysis of recent North Texas earthquake sequence reveals geologic fault, epicenters in Irving and West Dallas

Locations of seismic instruments as of Jan. 30, 2015, with revised earthquake locations in dark red. (USGS)Initial results from the seismology team at Southern Methodist University reveal that a recent series of earthquakes near old Texas Stadium in the Dallas-Fort Worth area were relatively shallow and concentrated along a narrow two-mile line that indicates a fault extending from Irving into West Dallas. SMU and the United States Geological Survey have shared an interim report with the mayors of Dallas and Irving. 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.
