The Milky Way is a large spiral galaxy surrounded by dozens of smaller satellite galaxies. Scientists have long theorized that occasionally these satellites will pass through the disk of the Milky Way, perturbing both the satellite and the disk. A team of astronomers from the U.S. and Canada, including one professor from the University of Kentucky, have discovered what may well be the smoking gun of such an encounter, one that occurred close to our position in the galaxy and relatively recently, at least in the cosmological sense.

“We have found evidence that our Milky Way had an encounter with a small galaxy or massive dark matter structure about 100 million years ago,” said Larry Widrow, professor at Queen’s  University in Canada. “We clearly observe unexpected differences in the Milky Way’s stellar distribution above and below the Galaxy’s midplane

What used to be a standard component for universities with archaeology programs is becoming increasingly rare: field school — an experiential course in which students excavate real archaeological sites. However, the UK Department of Anthropology has remained firmly committed to providing opportunities for students to dig into real-world experience.

Christopher Crawford, professor in the Department of Physics and Astronomy, recently received a prestigious five-year, $750,000 grant from the U.S. Department of Energy's 2012 Early Career Research Program.

The program supports the development of individual research programs of outstanding scientists early in their careers and stimulates research careers in the disciplines supported by the DOE Office of Science. Crawford's award will allow him to study the forces that hold the atomic nucleus together and that cause nuclear decays.

"I study symmetries of these forces," Crawford said. "There are certain properties of neutron postulated

Seven University of Kentucky students in the College of Arts & Sciences have been awarded the Benjamin A. Gilman International Scholarship to study abroad. These students are among 2,300 U.S. undergraduates who will be participating in programs abroad during the summer, fall, or 2012-2013 academic year.

The Gilman Scholarship Program offers awards to U.S. undergraduates who are receiving Federal Pell Grants at a two-year or four-year college or university to study abroad. Scholarships of up to $5,000 may be awarded and vary depending on the length of study and student need. The average award amount is approximately $4,000.

The Gilman Scholarship program supports a diverse group of students who have

Stargazing is typically reserved for after sundown, but what if you want to look at the biggest star in the sky? On June 5th, 2012, the planet Venus was visible by day – traveling in front of the sun! This is called the Transit of Venus, and is a rare astronomical event. A few hundred people gathered at the UK Arboretum to view the transit of Venus through special telescopes that allow safe observation of solar activity. In this podcast, we went to the Arboretum to talk to participants and Tim Knauer, the director of the MacAdam Student Observatory on UK's campus. The viewing was sponsored by the UK Physics & Astronomy Department and was done in conjunction with the Kentucky SkyTalks

Nina Elliott and Elizabeth Walsh have assembled an impressive list of accomplishments at UK this year, from creating new derivatives of the molecule phenothiazine, to potentially increasing performance of lithium-ion batteries, to co-authoring a paper in preparation for publication. Their next task to check off: graduating from high school.

Susan Odom, an assistant professor in the Department of Chemistry, has hosted the two Paul Laurence Dunbar High School students in her chemistry laboratory over the past semester. Elliott and Walsh assisted Odom in a project involving specific organic molecules and their utility

Archaeologists at the University of Kentucky, having completed a geophysical survey, will begin limited excavations at Fort Boonesborough State Park from June 18-22, in search of archaeological evidence of a Revolutionary War siege.

The Siege of 1778  was a prolonged engagement that pitted a party of French Canadians and American Indians against settlers living in the stockaded fort at present day Fort Boonesborough State Park in Madison County. The project, funded by a grant from the American Battlefield Protection Program, began in May 2012 with remote sensing surveys of the fort site and a nearby site that may have been part of the large American Indian encampment during the siege.

UK graduate Casey Carmichael, who earned his master's degree from the Department of Classics in 2010, was recently awarded a six-month doctoral fellowship from the Leibniz Institute for European History in Mainz, Germany.

The fellowship funds doctoral and post-doctoral candidates to conduct research projects at the Leibniz Institute, an independent research organization that facilitates historical research related to Europe. Carmichael will research and write his doctoral dissertation for the theology faculty at the University of Geneva from July-December 2012.

“Receiving the fellowship has brought me great joy and an added sense of motivation to pursue my doctoral research,” Carmichael said.

A new study by University of Kentucky researchers shows how light and strained ruthenium-based drugs may be more effective at fighting cancer cells and less toxic to healthy cells than a similar and widely used drug.

Cisplatin is a common platinum-based cancer drug. But while cisplatin kills cancer cells, it also attacks healthy cells, causing debilitating side effects. Ruthenium is a rare transition metal also belonging to the platinum group of the periodic table, and the UK researchers developed two new ruthenium complexes designed to kill cancer cells while preserving healthy cells.

These complexes are inert in the dark, but when activated with light, they become up to 200 times as toxic, and up to three times as potent as cisplatin against tumor cells.

The University of Kentucky recently received an $880,523 grant from the U.S. Department of Energy (DOE), as part of the DOE's Nuclear Energy Programs' $36.2 million initiative to enhance energy research and development projects.

This grant, titled "Elastic/Inelastic Measurement  Project," will center upon fuel cycle research and development. A consortium of three universities and a national laboratory has been formed to provide the necessary breadth for this effort, including scientists with extensive experience in neutron elastic and inelastic scattering measurements and with direct access to the facilities for completing the proposed neutron measurements, i.e., the UK Accelerator Laboratory.

Approximately 350 people turned out at The Arboretum Tuesday, June 5, to witness an astronomical phenomenon, not to occur again in this lifetime.

The transit of Venus, in which Venus traveled directly between Earth and the sun, began at 6:04 p.m. and could be seen from Lexington for approximately three hours.  

The MacAdam Student Observatory and the Bluegrass Amateur Astronomy Club provided telescopes and instruction for safely observing the phenomenon, as cloud cover allowed.

Tim Knauer, director of the MacAdam Student Observatory, said that he was pleased with the turnout.

"I thought given the weather, the response was good," Knauer said. "If
