Skeletal Muscles Do Not Undergo Apoptosis During Either Atrophy or Programmed Cell Death-Revisiting the Myonuclear Domain Hypothesis

Lawrence Schwartz published a review/commentary in 2019 in Frontiers in Physiology that described work from his lab and others demonstrating that skeletal muscles do not undergo apoptosis, a well studied mechanism of cell death. This observation has significant implications for the exercise physiology and the fate of muscles.

The work was picked up by the media and resulted in stories in NPR, BBC, and many news outlets around the world. Recently, the paper achieved more than 40,000 views.

Much of this work is based on their study of the intersegmental muscles (ISMs) from the tobacco hawkmoth Manduca sexta. These giant cells undergo sequential programs of atrophy and death at the end of metamorphosis.

More recently, the Schwartz Lab had two major papers published that follow up on the original study. These papers detail all of the changes in gene expression that mediate muscle atrophy and death, identify the molecular mechanisms that mediate cell death, and describe a new signal transduction pathway that includes two new genes (discovered in his lab!).

Digital Life Team Led by UMass Amherst Biologist Duncan Irschick Creates Great Hammerhead 3D Model

The Digital Life Project directed by Duncan Irschick has partnered with the marine science nonprofit ANGARI Foundation and underwater camera pioneer Casey Sapp for a research expedition to Bimini, The Bahamas, to create an accurate 3D model of a great hammerhead shark to share with scientists, educators and storytellers.

Tracking Shape Changes in Amazon Fish After Major River is Dammed

A team of biologists led by Craig Albertson and Ph.D. student Chaise Gilbert report this week on their comparison between museum collections of cichlid fishes collected before a dam was closed in 1984 on the Tocantins River in the Amazon and contemporary specimens taken from the Tucuruí Reservoir by fishermen 34 years later.

Cichlid fishes are able to respond rapidly to environmental change and offer a good model.

Pallas appointed as ADVANCE Fellow

Sarah Pallas is teaching a course on Developmental Neurobiology for the first time at UMass this semester.

Dr. Pallas has also been appointed as an ADVANCE fellow this year. A UMass ADVANCE Faculty Fellowship provides faculty members with a unique opportunity to participate in ADVANCE’s program of institutional transformation. Fellows will partner with the ADVANCE Leadership Team, which will provide the resources, recognition and relationship building necessary to help faculty collaborate successfully and feel valued and included. Fellows provide recommendations and feedback to the team about ADVANCE programming, and they liaise with their departments, and promote our efforts.

Funded by the National Science Foundation ADVANCE Program, UMass ADVANCE focuses on equity for women faculty in Science, Technology, Engineering and Math (STEM) by gender, race/ethnicity, sexuality, gender identity, nationality, and other statuses. Read more HERE!

Healey Receives Chancellor's Leadership Fellowship

The Office of Faculty Development has announced that Dr. Healey, Senior Lecturer of Biology, has received a 2020 Chancellor’s Leadership Fellowship.

John McCarthy, provost and senior vice chancellor for academic affairs, says, “With this latest cohort of Chancellor's Leadership Fellows, our campus continues the important work of preparing the next generation of academic leaders. In keeping with the program's goals, this year's cohort brings very great diversity of disciplines, backgrounds and career paths.”

Healey’s research expertise is in evolutionary biology and behavioral ecology. Healey has taught writing classes as a Quin-Morton Fellow in the Princeton Writing Program at Princeton University and was a faculty member at UCLA before joining the UMass faculty in 2010. She has taught topics ranging from HIV/AIDS and writing to introductory biology, ecology and evolution. She has employed numerous pedagogical approaches depending on class size and learning objectives, including community engagement, team-based learning and flipped classroom approaches. Healey has served as chair of the biology curriculum committee and has been elected chair of the UMass Undergraduate Education Council. Healey was awarded the College of Natural Science Outstanding Teaching Award in 2017. More recently, she was the first recipient of the Mahoney Teaching Award to join the team of faculty in the iCons program.
