Intense light from the enormous explosion of a star more than 12 billion years ago — shortly after the Big Bang — recently reached Earth and was visible in the sky.
Known as a gamma-ray burst, light from the rare, high-energy explosion traveled for 12.1 billion years before it was detected and observed by a telescope, ROTSE-IIIb, owned by Southern Methodist University, Dallas. Continue reading
The study by researchers at Southern Methodist University is the first large-scale longitudinal study of its kind to demonstrate the reading potential of students with intellectual disability or low IQ. It was funded by the U.S. Department of Education. Continue reading
Paleontologists at Southern Methodist University have measured the carbon isotopes in marine fossils from Bentiaba, Angola to precisely date for the first time 30 million years of sediments along Africa’s South Atlantic shoreline.
They dated the richest marine reptile fossil bed along Africa’s South Atlantic to 71.5 million years ago. Continue reading
Comet theory false; doesn’t explain cold snap at the end of the Ice Age, Clovis changes or mass animal extinction
As proof, proponents point to sediments with deposits they believe could only result from a cosmic impact. A new study disproves the theory, said lead-author and archaeologist David Meltzer, SMU. 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.
