Cockatoo Dances to the Beat

The movie shows three excerpts of videos analyzed in this experiment. Each excerpt is at a tempo different from the original song (Everybody, by the Backstreet Boys; 108.7 beats per minute [bpm]). The excerpts include synchronized bouts, periods during which Snowball bobs his head in synchrony with the musical beat for at least 12 consecutive bobs.

Induction of hematopoietic stem cells in zebrafish

This animation shows the different steps of hematopoiesis. Blood flow is required for the initial induction of hematopoietic stem cells, as shown in a paper by North et al. Cell. 2009 May 15;137(4):736-48. www.cell.com

Rook uses stones to raise water level and get food 1

The first trial in which the rook Connelly is required to raise the water level by a varying amount. In this trial, seven stones are needed to raise the water level and worm to the reachable height. Connelly flies to the testing platform and investigates the apparatus before the stones are added. Connelly adds seven stones before successfully acquiring the worm. He then leaves the testing platform. See the paper by Bird and Emery in Current Biology 19(16): www.cell.com ... Rooks bird emery ...

Chimp Tool Use in Budongo Forest: The Sonso Community

Chimpanzee populations throughout Africa differ in tool-using behavior, a likely example of animal culture. We exposed two Ugandan groups at Sonso and Kanyawara to an unfamiliar problem, honey trapped within a fallen log. We found that individuals relied on their cultural knowledge to solve this problem. The video shows how a Budongo chimpanzee produces a leaf-sponge to access the honey. See the paper by Gruber et al., Current Biology 19(21), published online Oct. 22, 2009: www.cell.com ...

Rook uses stones to raise water level and get food 4

Cook selectively drops stones into the tube containing water rather than the tube containing sawdust. Cook flies to the testing platform and investigates both tubes before the stones are added. Cook adds four large stones to the water before successfully acquiring the worm. He then leaves the testing platform. See the paper by Bird and Emery, Current Biology 19(16): www.cell.com

Facial communication between mother and infant macaque monkeys 1

Mother macaque interacting with her infant. The mutual gaze is sustained and is interrupted by gaze shifts, apparently aimed at attending the object of interest of her infant. During this face-to-face interaction, the mother is gently pulling the infant's head and seems to be particularly attracted by the eyes of the infant. What we found very common are the lipsmacks that are documented in this video. These mouth-face contacts closely resemble the human kiss. We can only speculate about the ...

Facial communication between mother and infant macaque monkeys 2

A mother gesturing at her 6-day-old infant. The type of gestures that can be observed (lipsmacking and teeth-chatter) are common among rhesus macaques. What is striking here is the exaggeration of the gesture that is accompanied by head-bobbings in order to further attract infant attention. This seems to be specific to mother-infant relationship. The exaggeration of facial displays and other modifications of the behavior in humans (eg, the high pitch in the voice) are typical ways of ...

"How has consumer spending changed over the past 15 years? Do we spend more on some things and spend less on other than we did in the early 80s? In this interactive, based on data from the Bureau of Labor Statistics, you can explore just that." - Tom Stocky
Hm.. looks like the insurance companies are getting rich. THe amount spent on personal insurance and healthcare has gone way up! - Piaw Na
What's interesting is that personal insurance growth is non-linear. There was a huge 2% jump around 2000. What explains this? Besides the recession, was there some big legislative change that year? 9/11? - Ray Cromwell
