Puchner group makes breakthrough in understanding the way cells use fat

A research team at the University of Minnesota has made a breakthrough in understanding the way cells use fats. This discovery will help scientists better understand this process which is linked to a number of diseases including diabetes and obesity. Elias Puchner, Assistant Professor at the School of Physics and Astronomy recently published a paper in Nature Communications describing a novel technique for super resolution microscopy that they used to study fasted living cells.

Unscrambling the Aurora

A team led by John Dombeck, a researcher in the University of Minnesota’s Minnesota Institute for Astrophysics, recently made a leap forward in the understanding of the mechanism that drives the aurora. Read more >>

Telescope taking shape in Physics High Bay

Twenty two tons of precision welded steel are coming together in the Physics and Nanotechnology building high bay to form the BICEP Array telescope that will be deployed to the South Pole at the end of 2019. The pieces of the telescope began arriving last September and since then, Professor Clem Pryke and his group have been busy working to put them together. More »

Robert Schwarz at the South Pole

UMN Physicist has spent more winters at the South Pole than anyone else

University of Minnesota astrophysicist Robert Schwarz holds the record for spending the most number of winters--14--at the South Pole. More »

Minnesota Astrophysicists Help Spot Rare Stellar Collision

Researchers, including astrophysicists from the University of Minnesota, have identified a white dwarf/brown dwarf collision in the star CK Vulpeculae. Professors Charles Woodward and Robert Gehrz are part of the Atacama Large Millimeter/submillimeter Array (ALMA) collaboration that discovered the object, long thought to be a nova, is actually a remnant of a rare type of solar collision.

The farthest star helps probe dark matter

Assistant Professor Patrick Kelly led a team of researchers that set a distance record and discovered the farthest individual star ever seen. The star, nicknamed Icarus, is 9 billion light-years away--halfway across the visible universe--and would ordinarily not be visible even to the most powerful telescopes. Gravitational lensing allowed the Hubble Space Telescope to pick out Icarus, whose official name is MACS 1149+2223 Lensed Star 1. The unique opportunity to study Icarus also allowed researchers to rule out one of the theories about the mystery of dark matter. More »

Linday Glesener and Kendra Bergstedt

Space Physicist to provide exciting research opportunities for students

Lindsay Glesener is a faculty member in the School of Physics and Astronomy, studying high energy events in the Sun. Glesener uses x-rays to observe solar flares and coronal mass ejections. These events throw intense amounts of of plasma and radiation into space, causing the Earth’s aurorae and causing high radiation environments in Earth’s orbit, adversely affecting spacecraft. Glesener studies this topic from a fundamental physics perspective, trying to answer remaining questions about how these solar events are energized and the high-energy nature of the Sun. More »

Guichuan Yu

Master of Mercury Barium Copper Oxides

Researchers at the School of Physics and Astronomy are trying to solve a thirty year old mystery: what causes high-temperature superconductivity? Guichuan Yu is a postdoc in a lab that is entirely focused on the problem. Yu has been with Martin Greven’s superconductivity laboratory since he was a graduate student and has spent the past ten years refining the technique of creating one class of materials, Mercury Barium Copper Oxides. As a postdoc he is now in charge of growing the single crystal samples the group uses in their experiments. More »
