Marmoset monkeys learn to call the same way human infants learn to babble
A baby's babbles start to sound like speech more quickly if they get frequent vocal feedback from adults. Princeton University researchers have found the same type of feedback speeds the vocal development of infant marmoset monkeys, in the first evidence of such learning in nonhuman primates.
Study identifies RNA molecule that shields breast cancer stem cells from immune system
Researchers from Princeton University’s Department of Molecular Biology have identified a small RNA molecule that helps maintain the activity of stem cells in both healthy and cancerous breast tissue. The study, which will be published in the June issue of Nature Cell Biology, suggests that this "microRNA" promotes particularly deadly forms of breast cancer and that inhibiting the effects of this molecule could improve the efficacy of existing breast cancer therapies.
New model helps predict regional and seasonal sea ice extent
Scientists have developed a new method to forecast the extent of sea ice in some regions of the Arctic up to 11 months in advance. The method, which incorporates information about ocean temperatures and focuses on regions rather than the entire Arctic Sea, could help in the planning of activities ranging from shipping to oil and gas extraction, fishing and tourism.
