Behavioral observation has become a fundamental component of medical practice and a primary source of clinical research data. The use of video technology in nurse-patient interaction research offers important advantages to scientists in unraveling complex behavior patterns and finding relationships between behaviors, nutrition, effectiveness of interventions, and more.

Measuring changes in captive great ape welfare and conservation attitudes
Any insect that flies at night must deal with bat predation. Take a moth, for example. Moths arrived first on the evolutionary stage; when much later on bats appeared with their sophisticated apparatus for echolocating prey, moths were forced to change or die. Some species developed ears to hear the approach of a bat; this generally evokes evasive flight maneuvers like loops and dives. Other species acquired distasteful chemicals that gave them a repugnant or poisonous taste. Some even developed the ability to produce sounds that seem to confuse, and sometimes thwart, an attacking bat.
My mother makes the best apple crumble. The top is crunchy, the apples warm and mushy (but not too mushy!), and the level of cinnamon is in perfect balance with the sugar and the apples. Honestly, I’ve never tasted a more delicious apple crumble, which sets a high standard for friends or restaurants offering me an apple crumble dessert.
We have learned that zebrafish have much more in common with humans than meets the eye, which is why they have become a “go-to” model in neuroscience research. But one obvious difference remains: we walk and they swim, which means movement in 3 dimensions. So while video tracking from one camera angle (e.g. above) can give us a lot of information about the movement of humans (or rodents), all the information from the third dimension (depth) is entirely missed from single camera tracking.
It shouldn’t, but it does.
Although men and women are equally at risk for sudden cardiac arrest, studies have found that women are less likely to be resuscitated – by both bystanders and medically-trained personnel. Chelsea Kramer and her colleagues discovered that in the experiment they set up, when faced with either a male or female patient simulator, both men and women rescuers appeared reluctant to remove a female patient simulator’s clothing, with men being significantly more hesitant to do so. However, the hand placement for CPR on the female was more ideal compared to on the male simulated patient.
Wild and appealing public displays
For public displays nowadays, we are no longer limited to traditional square and flat designs. More wild and appealing forms like curves, spheres, or columns are now possible as well. People that pass by such displays may behave differently than when they see a traditional square and flat one. This effect may be unwanted and people might miss important information on the display because they mainly look at other eye-catching parts. But it also offers interesting possibilities to manipulate the people passing by the display. If you know how the display shape influences people, you can use this knowledge to optimize information transfer.
