Groundbreaking research led by a team of scientists including a University of Massachusetts Amherst biostatistician shows that oral hormone therapy (HT) significantly alters the metabolome of postmenopausal women. This finding, which examined blood specimens from the landmark Women s Health Initiative (WHI) study, may help explain the disease risks and protective effects associated with different regimens of hormone therapy. This is the first analysis of the metabolomic effects of hormone therapy conducted within the framework of a randomized clinical trial, says Raji Balasubramanian, associate professor in the School of Public Health and Health Sciences, whose research connects biostatistics, molecular epidemiology and women s health.
This month, Google forced out a prominent AI ethics researcher after she voiced frustration with the company for making her withdraw a research paper. The paper pointed out the risks of language-processing artificial intelligence, the type used in Google Search and other text analysis products. Among the risks is the large carbon footprint of developing this kind of AI technology. By some estimates, training an AI model generates as much carbon emissions as it takes to build and drive five cars over their lifetimes. I am a researcher who studies and develops AI models, and I am all too familiar with the skyrocketing energy and financial costs of AI research. Why have AI models become so power hungry, and how are they different from traditional data center computation?

People used to say Jaeâda Turner was stuck in Boston.
Because Black folk from outside of the city often see it as a place to pass through but not plant roots. Those people are not from here.
Turner isnât trapped. Sheâs at home.
âHaving to defend Boston is a real sport,â Turner says. âAs a student at Northeastern, people coming from New York, California, and all across the country, I think they honestly love to hate Boston. Itâs like a little club. Itâs not cool if you say youâre from Boston.â

It s one of the most violent spectacles in the natural world: Two bighorn sheep square off at 10 paces, rear up on their hind legs and rush, dropping their heads at the last moment to crash their horns together with maximum impact. And then they do it again, sometimes for hours on end, before walking away apparently no worse for the wear.
Bucknell Professor Benjamin Wheatley, mechanical engineering, occasionally witnessed these clashes in Estes Park, Colo., while he was studying for his doctorate at nearby Colorado State University. It sparked his curiosity. If such similarly violent head-to-head collisions result in concussions and even life-threatening injuries for football players, he wondered, how can these sheep avoid such trauma? What might we learn
