Cell biologists identify new protein key to asymmetric cell division

Recently a research team led by Wei-lih Lee, associate professor of Biology, identified a new molecular player in asymmetric cell division, a regulatory protein named She1 whose role in chromosome- and spindle positioning wasn’t known before. Asymmetric cell division is important in the self-renewal of stem cells and because it ensures that daughter cells have different fates and functions.
 
When a fertilized egg develops in a fruit fly or a human being, the number of asymmetric cell divisions must be precisely balanced by symmetric cell divisions, Lee explains.

CASA installs its first weather radar in Texas

Brenda Philips, deputy director of the College of Engineering’s Collaborative Sensing of the Atmosphere (CASA) program, with engineer Eric Lyons and innovation manager Apoorva Bajaj, were on hand Oct. 28 as the first CASA weather radar unit was installed by helicopter atop a building at the University of Texas Arlington (UTA).
 
Philips said, “This represents a great technical and organizational milestone for the project.” Over the next several months it will see three more CASA units installed at partner institutions in the Dallas-Fort Worth metro area, with support from the North Texas

Ceremonies mark launch of construction of new classroom building

University officials last week celebrated the launch of construction of a $95 million New Academic Classroom Building (NACB) that will provide state-of-the-art academic space and create a new hub of student activity near the Campus Center and Student Union. The event was held Oct. 26 in the Student Union Ballroom.
 
The four-story, 171,500-square-foot building located off North Pleasant Street at the north end of the Campus Pond is scheduled for completion in the spring of 2014.

Campus closes in advance of Hurricane Sandy's arrival

With forecasters predicting heavy rain, strong winds, power outages and flooding in the region due to Hurricane Sandy, university officials announced that UMass Amherst and its off-campus facilities around the state will be closed Oct. 29.

The closing notice was communicated to students, staff and faculty through broadcast e-mails, text messages, the recorded emergency closing telephone line and via the campus's website. The notice was also distributed to local television and radio outlets.

The closure decision came after Gov.

Helfer receives $1.3 million to study hearing and aging

Karen Helfer, associate professor of Communication Disorders, has received a five year, $1.3 million grant from the NIH’s National Institute for Deafness and Other Communication Disorders to conduct a series of studies to determine what is going on in difficult listening situations where hearing aids often don’t help, and explore ways to assist millions of older Americans to do better.

Though most people with hearing loss are treated with hearing aids, the devices are not very helpful in situations where many people are talking at once or there is background noise, says Helfer, an expert in
