Science: What Caused a 1300-Year Deep Freeze?

SMU, comet, Meltzer, Clovis points, ScienceThe widely followed science news outlet Science covered the research of SMU archaeologist David J. Meltzer with the article What Caused a 1300-Year Deep Freeze?

The Science piece by Michael Balter highlights Meltzer’s new study showing a comet was not responsible for sudden climate change at the end of the Ice Age. Proponents of the comet-impact theory have pointed to sedimentary deposits that they say prove a comet hit the Earth, killing the Clovis culture and causing mass extinction of many animals.

Nature: Prehistoric impact idea smacked down — dates of reported cosmic collision can’t explain North American extinctions

Meltzer comet, Nature magWidely followed science magazine Nature covered the research of SMU archaeologist David J. Meltzer with the article Prehistoric impact idea smacked down.

The Nature piece by Alexandra Witze focuses on Meltzer’s latest study to show that a comet was not responsible for sudden climate change at the end of the Ice Age 12,800 years ago. Proponents of the comet-impact theory have pointed to sedimentary deposits that they say prove that an object from outer space hit the Earth, killing the Clovis culture and causing the mass extinction of many animals.

Comet theory false; doesn’t explain cold snap at the end of the Ice Age, Clovis changes or mass animal extinction

Comet, Meltzer, SMU, Clovis, boundary layerControversy still rages over what sparked climate change at the end of the Ice Age 12,800 years ago, including a theory it was caused by a comet hitting the Earth.

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

Satellite view of volcanoes finds the link between ground deformation and eruption

Great Rift Valley in East Africa volcano upliftUsing satellite imagery to monitor which volcanoes are deforming provides statistical evidence of their eruption potential, according to a new study in Nature Communications.

The European Space Agency’s Sentinel satellite, launched April 3, should allow scientists to test this link in greater detail and eventually develop a forecast system for all volcanoes, including those that are remote and inaccessible. Continue reading

SMU Daily Campus: SMU seismologists investigate cause of North Texas earthquakes

SMU Heather DeShon earthquakes seismologyJournalist Jehadu Abshiro of the SMU Daily Campus covered the research of SMU seismologist Heather R. DeShon.

DeShon is leading the effort to trace the source of a recent sequence of small earthquakes in North Texas and any relationship they may have to the injection of waste water by energy companies using shale gas production to recover gas.

NOvA experiment glimpses neutrinos, one of nature’s most abundant, and elusive particles

NOvA, SMU, Tom Coan, neutrinos 400x300Scientists hunting one of nature’s most elusive, yet abundant, elementary particles announced today they’ve succeeded in their first efforts to glimpse neutrinos using a detector in Minnesota.

Neutrinos are generated in nature through the decay of radioactive elements and from high-energy collisions between fundamental particles, such as in the Big Bang that ignited the universe. Continue reading
