Reducing Myc gene activity extends healthy lifespan in mice

: Mice with one rather than the normal two copies of the gene Myc (also found in humans) lived 15 percent longer and had considerably healthier lives than normal mice, according to a new Brown University-led study in Cell.

On the ups and downs of the seemingly idle brain

Even when it seems not to be doing much, the brain maintains a baseline of activity in the form of up and down states of bustle and quiet. To accomplish this seemingly simple cycle, it maintains a complex balance between the activity of many excitatory and inhibitory cells, Brown University scientists report in the Journal of Neuroscience.

Diabetes risk varies with Mg intake, genes, ethnicity

A new study investigated the complex interactions between magnesium intake, genes, and ethnicity in determining risk for type 2 diabetes in two populations of women. The specific associations yielded by the analysis illustrate how health guidance could become considerably more personalized.
Questions for Sohini Ramachandran

Probing the deep history of human genes and language

Brown University evolutionary biologist Sohini Ramachandran has joined with colleagues in publishing a sweeping analysis of genetic and linguistic patterns across the world’s populations. Among the findings is that geographic distance predicts differentiation in both language and genes.

Juried ceramics show at the Bell Gallery

The David Winton Bell Gallery presents the 2015 NCECA Biennial, an international juried ceramics exhibition, on view from Saturday, Jan. 24, through Sunday, March 29, 2015. The exhibition is mounted in conjunction with the 49th Annual National Council on Education for the Ceramic Arts Conference at the Rhode Island Convention Center March 25-28, 2015.

Study IDs risk factors linking low birthweight to diabetes

A new study of more than 3,000 women confirms that low birthweight predicts an increased risk of type 2 diabetes in adulthood and reports which intermediating biomarkers appear to be the best predictors. The research could help physicians better assess patient risk.

Researchers study marine ecological changes at Easter Island

Late last year, Jon Witman and Robert Lamb spent three weeks studying coral and other marine life in the waters around Easter Island, part of a research project led by Universidad Catolica de Santiago de Chile. Unlike most of the world, the coral around Easter Island appears to be increasing.

Bacteria could be rich source for making terpenes

New research at Brown University and in Japan suggests bacteria could be a rich source of terpenes, the natural compounds common in plants and fungi that are used to make drugs, food additives, perfumes, and other products.

New technology makes tissues, someday maybe organs

A new device for building large tissues from living components of three-dimensional microtissues borrows on ideas from electronics manufacturing. The Bio-Pick, Place, and Perfuse (BioP3) is a step toward someday making whole organs. A new grant from the National Science Foundation will allow for major improvements including automation.

Patients rarely learn of at-home provider quality data

Patients discharged from the hospital could access state or federal quality reports about home health agencies. A new study, however, finds that patients, their families, and their care managers rarely, if ever, see these reports when deciding which agency to retain.
