Making Choice Chambers ExpandBefore beginning the experiments, use one of the Sharpies from the lab table to trace a line around the circumference of the bottom of both bottles. One line should be 1 cm from the base of the bottle and the other should be 1.5 cm from the base of the bottle. Use a razor blade to make a small cut in each bottle at the mark. Then, insert the scissors and carefully cut along the line until the bottoms of the bottles are removed completely. Fit one bottle bottom into...

Graphene Biosensor-Based Field-Effect Biosensing to Detect Protein-Protein Interactions

In this video, we describe the field-effect biosensing (FEB) technology to detect and quantify protein-protein interactions. The target proteins immobilized on the graphene biosensor interact with analyte proteins in solution, resulting in electrical current alterations in the FEB system. This change in the electrical response indicates the binding affinity between the proteins.

Source: Arianna Brown, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA Waves are disturbances that propagate through a material medium or empty space. Light waves can travel through a vacuum and some forms of matter, and are transverse in nature, which means that the oscillations are perpendicular to the direction of propagation. However, sound waves are pressure waves that travel through an elastic medium like air,...

We demonstrate how an objective measure can be employed in the widely employed rubber hand illusion paradigm. This measure is obtained by modifying the well-established crossmodal congruency task. This task allows the investigation of multisensory processes which are critical for modulations of body representations as in the rubber hand illusion.

Identification of suspected stroke in the dispatch center of the Berlin Fire Brigade prompts the deployment of a CT-equipped ambulance. If ischemic stroke is confirmed and contraindications are excluded prehospital thrombolysis is applied.
FAQs
Alarm-call information can be conveyed through differences in call features, not only through the presence of a signal. When features vary with the type or urgency of danger, nearby animals may receive cues about the situation and select an appropriate response. This helps explain how vocal signaling connects an individual’s detection of risk with group-level defensive behavior.
These responses represent different behavioral adjustments to danger. Freezing or hiding may reduce exposure, fleeing creates distance from the threat, and mobbing directs group behavior toward the predator. Increased vigilance provides another way to manage risk. Studying which response follows a call helps researchers connect acoustic information with how animals protect themselves and others.
Alarm calls can distribute information about danger beyond the individual that first detects it, allowing nearby animals to change their behavior. This information-sharing can support coordinated defensive responses and influence survival within social groups. Over time, the relationship between signaling, cooperation, and survival provides a biological context for investigating how natural selection shapes communication systems.
The spread of an alarm signal and the responses of nearby individuals provide evidence about how animals function as groups. Researchers can examine whether information leads to coordinated vigilance, hiding, flight, or mobbing, and how group members react to one another during danger. These patterns help connect communication behavior with social organization and cooperation.
A study can relate the individual that detects danger, the acoustic features of its signal, the apparent type or urgency of the threat, and the behavior of nearby listeners. Researchers then consider whether listeners freeze, flee, hide, mob, or increase vigilance. Comparing these elements helps identify how information moves from detection to behavioral response.
Alarm calls provide a way to examine the link between predator presence and prey behavior. Researchers can compare the danger associated with a signal, features that may vary with threat type or urgency, and the defensive actions of listeners. This reveals how communication modifies prey responses while placing signaling within the broader dynamics of predator-prey interactions.
