Video: Rare primate's vocal lip-smacks share features of human speech The vocal lip-smacks that geladas use in friendly encounters have surprising similarities to human speech, according to a study reported in the Cell Press journal Current Biology on April 8th. The geladas, which live only in the remote mountains of Ethiopia, are the only nonhuman primate known to communicate with such a speech-like, undulating rhythm. Calls of other monkeys and apes are typ
Protein maintains order in the nucleus Two metres of DNA are packed into the cell nucleus, presumably based on a strictly defined arrangement. Researchers working with biologist Patrick Heun from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg have now succeeded in explaining a phenomenon, which was first observed 40 years ago.
Nothing fishy about it: Fish oil can boost the immune system Fish oil rich in DHA and EPA is widely believed to help prevent disease by reducing inflammation, but until now, scientists were not entirely sure about its immune enhancing effects. A new report appearing in the April 2013 issue of the Journal of Leukocyte Biology, helps provide clarity on this by showing that DHA-rich fish oil enhances B cell activity, a white blood cell, challenging the

Researchers show stem cell fate depends on 'grip' The field of regenerative medicine holds great promise, propelled by greater understanding of how stem cells differentiate themselves into many of the body's different cell types. But clinical applications in the field have been slow to materialize, partially owing to difficulties in replicating the conditions these cells naturally experience.

Sustainable fishing practices produce local rewards Communities that act locally to limit their fish catches will reap the rewards of their action, as will their neighbors. That's the conclusion of a study reported on March 28 in the Cell Press journal Current Biology of the highly sought-after fish known as squaretail coral grouper living in five community-owned reef systems in Papua New Guinea.

In solving social dilemmas, vervet monkeys get by with a little patience People could learn a lot from vervet monkeys. When vervets need to work together, they don't tell each other what to do or punish uncooperative behavior. But according to evidence reported on March 28 in the Cell Press journal Current Biology, they do get by, with a little patience.

Researchers discover how model organism Tetrahymena plays roulette with 7 sexes It's been more than fifty years since scientists discovered that the single-celled organism Tetrahymena thermophila has seven sexes. But in all that time, they've never known how each cell's sex, or "mating type," is determined; now they do. The new findings are published 26 March in the open access journal PLOS Biology.

Compounds found that alter cell signaling, could lead to new breast cancer treatments Using a broad spectrum of analytical tools, scientists from the Florida campus of The Scripps Research Institute (TSRI) have uncovered a class of novel compounds that can alter cell signaling activity, resulting in a variety of responses including a strong anti-inflammatory effect. These findings could lead to new strategies for treating diseases such as breast cancer

Putting the clock in 'cock-a-doodle-doo' Of course, roosters crow with the dawn. But are they simply reacting to the environment, or do they really know what time of day it is? Researchers reporting on March 18 in Current Biology, a Cell Press publication, have evidence that puts the clock in "cock-a-doodle-doo" (or "ko-ke-kok-koh," as they say in the research team's native Japan).

Where, oh where, has the road kill gone? Millions of birds die in the US each year as they collide with moving vehicles, but things have been looking up, at least in the case of cliff swallows. Today's swallows are hit less often, thanks to shorter wingspans that may help them take off more quickly and pivot away from passing cars. The findings, reported in the Cell Press journal Current Biology on March 18, show that urban enviro

Polo takes the bait A seemingly obscure gene in the female fruit fly that is only active in cells that will become eggs has led researchers at the Stowers Institute for Medical Research to the discovery of a atypical protein that lures, traps, and inactivates the powerful Polo kinase, widely considered the master regulator of cell division. Its human homolog, Polo-like kinase-1 (Plk1), is misregulated

Sniff, sniff. What did you say? When animals like dogs or rats sniff one another, there might be more going on than you'd think. Research reported in Current Biology, a Cell Press publication, on March 7th finds in rats that those sniffing behaviors communicate information about an individual's social status. In those encounters, more dominant rats act as primary sniffers, while subordinate sniffees actually slow their br

New insight into double-protected dance of cell division Biochemists at the University of Massachusetts Amherst including assistant professor Peter Chien recently gained new insight into how protein synthesis and degradation help to regulate the delicate ballet of cell division. In particular, they reveal how two proteins shelter each other in "mutually assured cleanup" to insure that division goes smoothly and safely.

Protein paves the way for correct stem cell differentiation A single embryonic stem cell can develop into more than 200 specialized cell types that make up our body. This maturation process is called differentiation and is tightly regulated. If the regulation is lost, specialized cells cannot develop correctly during development. In adulthood, the specialized cells may forget their identity and develop into cancer cells. Research from BRIC, University of C
