Following its annual winter break, the most powerful collider in the world has been switched back on.
Geneva-based CERN’s Large Hadron Collider has been fine-tuned using low-intensity beams and pilot proton collisions. Now the LHC and its experiments are ready to take an abundance of data.
The goal is to improve understanding of fundamental physics, driving future innovation and inventions. Continue reading
A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, say astrophysicists at SMU.
The massive explosion, Supernova 2013j, was one of the closest to Earth in recent years. Analysis of the exploding star’s light curve and color spectrum found its sudden blast hurled material from it at 10,000 kilometers a second. Continue reading
Archaeologists in Italy have discovered what may be a rare sacred text in the Etruscan language that is likely to yield rich details about Etruscan worship and early beliefs of a lost culture fundamental to western traditions.
The lengthy text is on a large 6th century sandstone slab uncovered from an Etruscan temple. Continue reading
Counting calories burned is popular, but leading standardized equations used to predict or estimate calories burned while walking assume that one size fits all. They’ve been in place for close to half a century and were based on data from a limited number of people.
A new SMU study found that under firm, level ground conditions, the leading standards are relatively inaccurate and have significant bias — predicting too few calories burned in 97 percent of cases researchers examined.
Uplift 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
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
Should 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.
