Great Lakes Climate Modeling in the News

image98360-persPengfei Xue (CEE) and his modeling work through the Great Lakes Research Center, which led to a more comprehensive climate and hydrodynamics model for the whole Great Lakes region, has been featured in several science media outlets including Science Daily, Phys.org, Terra Daily and Supercomputing Online News. The story was shared numerous times by collaborators and the science community on Twitter.

Weather the Storm: Improving Great Lakes Modeling

The collaborative work brought together researchers from Michigan Technological University, Loyola Marymount University, LimnoTech and the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Laboratory. Pengfei Xue, an assistant professor of civil and environmental engineering at Michigan Tech, led the study through his work at the Great Lakes Research Center on campus.

One of the important concepts in climate change, in addition to knowing the warming trend, is understanding that extreme events become more severe. That is both a challenge and an important focus in regional climate modeling. —Pengfei Xue

SURF Applications Open

Cloud Chamber 201510230011Applications for 2017 Summer Undergraduate Research Fellowships are now open. Fellowship recipients will spend the summer on an individual research project under the guidance of a Michigan Tech faculty mentor. SURFs are open to all Tech undergraduates who have at least one semester remaining after the summer term. Awards are up to $4,000. Applications are due by 4 p.m. Jan. 27.

A workshop on writing effective SURF proposals is scheduled for 6 p.m. Monday, Dec. 5 in Fisher 132.

For more information, access to the application materials and instructions, visit the webpage or contact the SURF coordinator, Will Cantrell.

Jaszczak discovery is spreading across the world

image144299-persDozens of news outlets and science blogs have covered research by John Jaszczak (Physics) and his team that led to the discovery of the new mineral merelaniite.

Several of the outlets include United Press International, Australian Mining, Phys.org, the German blog Scinexx, several geology blogs like Geology In and Science Explorer. Local coverage in Tanzania has also been extensive including stories by the BBC and The Guardian in Swahili.

This Month in Astronomical History

Teresa Wilson’s monthly series “This Month in Astronomical History” has released its November publication “Launch of Sputnik 2”. Each month, as part of this new series from the Historical Astronomy Division of the AAS, an important discovery or memorable event in the history of astronomy will be highlighted. This month, we look as the Soviet Union’s launch of Sputnik 2. You can read the compete article here or on aas.org.

Jaszczak Leads Discovery of New Mineral

image144299-persA team led by a physicist from Michigan Tech has discovered a new mineral, named for the region in Tanzania where it comes from.

John Jaszczak knew that something was very unusual about the mineral specimen he was examining under the microscope of a Raman spectrometer in the basement of Fisher Hall.

On a hunch, Jaszczak decided to look into it further. The diagnostic studies with Raman spectrometry and scanning electron microscopy showed a layered structure rich in molybdenum, lead and sulfur that may be a new mineral. Now, Jaszczak and the team he pulled together can confirm that gut feeling. The tiny, silvery, cylindrical whiskers are indeed a new mineral—merelaniite. The journal Minerals published the team’s findings last week.

Detailed chemical and physical analyses of merelaniite—a member of the cylindrite group—revealed a neatly stacked layered structure with sheets rolled in scrolls like tobacco in a cigar. These tiny whiskers, which to the naked eye look like very fine hairs on other larger crystals, have probably been regularly cleaned off their host rocks containing other more recognizable minerals that occur at the famous gem mines near Merelani, Tanzania.

But it doesn’t negate the value of less showy minerals.
