Volume 20, Issue 5

On the cover: Semendwa, a bonobo at Lola ya Bonobo sanctuary in the Democratic Republic of the Congo, asks for a banana from one of the keepers who is handing out the afternoon snack. Her daughter Elikia waits at her feet, chewing on a piece of banana that Semendwa has dropped. In this issue, Hare and Kwetuenda (R230–R231) find that the bonobo, our closest living relative, voluntarily shares food not only with group mates but also with strangers. This behavior has not been documented in any other nonhuman primate, including our other closest living relative, the chimpanzee. Photo by Vanessa Woods.

Featured Video

A Correspondence in the March 9th issue by Hare and Kwetuenda reveals that, contrary to previous understanding, voluntary food-sharing is not unique to humans. This new study provides evidence that bonobos also freely and actively share their food with others, as shown in the video above.

Research Highlights

Online Ahead of Issue

Each week, Current Biology publishes papers online ahead of the print issue. Here are the latest:

Greenwood et al. Crowding changes appearance Akre and Ryan Mating signal complexity increases working memory

Featured Article

Methylation of H3K4 Is Required for Inheritance of Active Transcriptional States
Tetsuya Muramoto, Iris Müller, Giles Thomas, Andrew Melvin, and Jonathan R. Chubb

Muramoto

Here Chubb and colleagues explore the inheritance of transcriptional states via live imaging of single gene transcriptional events in individual cells and report a similar frequency of transcriptional firing in mother and daughter cells that requires methylation of histone H4 at Lys4.

The featured article is available FREE online.

Magazine Highlight

Minreview: The Bicoid Morphogen System
Aude Porcher and Nathalie Dostatni

Porcher

Here Porcher and Dostatni discuss recent work by developmental and cell biologists, theoreticians, and physicists that has examined how anterior patterning of the Drosophila embryo is achieved under the control of the morphogen Bicoid.

The magazine highlight is available FREE online.

Interview

For Current Biology's special review issue on the global history of Homo sapiens, Florian Maderspacher talks to noted archaeologist Colin Renfrew about human population history and archaeogenetics. The interview starts at 1:05 of the linked Cell Press podcast.
