“Researchers Create ‘Neural Tourniquet’ Method to Manage Bleeding by Activating a Targeted Nerve”

### The Neural Tourniquet: An Innovative Method for Managing Surgical Bleeding

In a significant advancement that could redefine surgical practice, scientists have unveiled a unique strategy to curb bleeding by activating the vagus nerve. Known as the “neural tourniquet,” this pioneering technique utilizes the body’s inherent processes to boost blood clotting, providing a forward-thinking solution to one of the surgical field’s most daunting issues: extensive blood loss.

#### The Importance of the Vagus Nerve

The vagus nerve, commonly called the “wandering nerve,” is an essential part of the autonomic nervous system. It links the brain to multiple organs, such as the heart, lungs, and digestive system, and is crucial for regulating various bodily functions including heart rate, digestion, and immune system response.

Recent studies have revealed yet another extraordinary function of the vagus nerve: its capacity to stimulate the body’s natural clotting processes. By applying targeted electrical impulses to the nerve, researchers can initiate a series of biological reactions that prepare the body to reduce blood loss in the event of injury.

#### Mechanism of the Neural Tourniquet

Dr. Jared Huston, a trauma surgeon spearheading the investigation, detailed the mechanics behind the neural tourniquet in a conversation with *LiveScience*. Upon stimulation of the vagus nerve, signals are dispatched to the spleen, activating immune cells known as macrophages. Subsequently, these cells signal platelets—the components in blood responsible for clotting—to become more reactive to potential injuries. This enhanced readiness allows the body to form clots more effectively, thereby diminishing the chances of excessive bleeding.

#### Encouraging Findings from Initial Research

The investigation commenced with animal testing involving mice and pigs, where nerve stimulation resulted in notable decreases in bleeding. Motivated by these findings, the team proceeded to conduct preliminary human trials, which produced similarly promising results. Participants who received targeted vagus nerve stimulation displayed increased markers of platelet activation in their blood samples, suggesting that the method could successfully improve clotting in humans as well.

#### Tackling a Major Medical Issue

Excessive bleeding during surgery persists as a major concern in contemporary medicine. Recent statistics indicate that around 1.5% of surgical procedures are complicated by significant blood loss, leading to prolonged recovery times, heightened medical expenses, and, in critical cases, life-threatening complications. Conventional techniques for controlling bleeding, such as sutures, clamps, and mechanical tourniquets, are reactive—they respond to bleeding after it occurs. The neural tourniquet, on the other hand, provides a preemptive strategy, equipping the body to lessen blood loss prior to the commencement of surgery.

#### Possible Uses in Medicine

The ramifications of this discovery are extensive. Surgeons might leverage the neural tourniquet as a preoperative tactic, applying brief nerve stimulation before scheduled operations, much like how they currently employ preventive antibiotics or analgesics. This method could offer an additional safeguard for patients, especially those undergoing high-risk surgeries or having conditions that hinder clotting, such as hemophilia or liver disease.

Furthermore, the technique may have applications beyond the operating room. Investigators are examining whether vagus nerve stimulation could assist in managing other forms of bleeding, such as internal bleeding due to trauma or gastrointestinal issues. If successful, this approach could become a flexible tool in emergency medicine.

#### Obstacles and Future Directions

While initial results are promising, researchers emphasize that more extensive clinical studies are required to confirm the technique’s safety and effectiveness in a wider array of medical contexts. There are still unanswered questions regarding the ideal duration and intensity of nerve stimulation, as well as potential side effects. Additionally, researchers must determine if the technique can be effectively applied in varied patient populations, including those with existing conditions that impact the nervous or circulatory systems.

The next stage of research will concentrate on evaluating the neural tourniquet in actual clinical scenarios where bleeding is a critical issue. These trials will yield essential information on the method’s practicality and effectiveness, paving the way for its eventual integration into standard medical practice.

#### A Shift in Surgical Medicine

If validated, the neural tourniquet could transform how healthcare providers manage surgical risks. By utilizing the body’s natural defense systems, this technique presents a safer, more effective way of controlling bleeding, lessening the reliance on invasive measures and enhancing patient outcomes.

As researchers strive to perfect this groundbreaking method, the neural tourniquet symbolizes the potential of innovative advancements in medicine. By linking neuroscience with surgical practice, this discovery has the capacity to save numerous lives and establish a new benchmark in patient care.

“Spiders Employ Sound to Initiate Targeted Web Assaults”

### The Intriguing Hunting Strategy of Slingshot Spiders: A Harmony of Sound and Precision

Slingshot spiders (*Theridiosoma gemmosum*), a small arachnid species measuring under one centimeter, have captivated researchers with their distinctive hunting method. These spiders do not solely depend on stealth or venom; instead, they adopt a ballistic approach, propelling themselves and their webs at unknowing prey. For years, scientists have pondered the mechanics behind their impressive accuracy, but a recent discovery has finally revealed the truth: sound.

Researchers from the University of Akron in Ohio have discovered that slingshot spiders utilize air vibrations—essentially sound waves—to find and home in on their prey with remarkable precision. This finding not only illuminates the spiders’ hunting capabilities but also emphasizes the broader significance of sound in spider behavior.

### An Extraordinary Hunting Method: The Slingshot Technique

Slingshot spiders derive their name from their exceptional hunting technique, which involves transforming their webs into a high-speed missile. At first glance, their webs may look like the typical orb webs fashioned by numerous spider species, yet these webs are anything but ordinary.

During the hunt, the spider positions itself at the center of the web, tugging on a silk thread secured to a nearby rock, branch, or structure. This movement stretches the web into a cone-like shape, storing potential energy much like a slingshot. Upon detecting prey, the spider lets go of the taut line, launching itself and the web towards the target at velocities of up to 4 meters per second—an impressive achievement for such a small organism.

For a considerable time, scientists thought that slingshot spiders waited for their prey to physically contact the web before initiating their attack. However, new studies have disproven this belief, showing that the spiders depend on a significantly more advanced sensory system.

—

### The Importance of Sound in Slingshot Spider Hunting

The groundbreaking research, published in *The Journal of Experimental Biology*, illustrates that slingshot spiders apply sound to identify and aim at their prey. Specifically, they sense the vibrations generated by the movement of their prey, like the wingbeats of a mosquito. These vibrations travel through the atmosphere and notify the spider of a potential meal.

To validate this theory, researchers executed two experiments. In the first, they introduced wing-flapping mosquitoes fixed to thin black construction paper into the spiders’ environments. In the second, they utilized a tuning fork to generate controlled vibrations. In both scenarios, the spiders reacted to the vibrations by releasing their webs, affirming that sound plays a crucial role in their hunting method.

Notably, the spiders’ sensitivity to sound is so acute that they can even be activated by noises made by humans, such as snapping fingers near their webs. This extraordinary capability highlights the significance of sound in their predatory actions.

—

### Accurate Timing and Angles: The Essential Elements for Success

The study also disclosed that slingshot spiders depend on precise timing and angles to enhance their success in catching prey. The spiders seem to gauge the direction and strength of the vibrations to determine the best moment to release their web. This split-second decision-making ensures that the web strikes the prey with remarkable accuracy.

The researchers observed that the spiders seldom miss their targets, even though the prey frequently does not physically touch the web. This observation challenges earlier beliefs regarding how spiders perceive and ensnare their prey, suggesting that sound-based hunting might be more prevalent among arachnids than previously recognized.

—

### Broader Implications for Spider Biology and Beyond

The revelation that slingshot spiders use sound for hunting carries wider implications for our comprehension of spider biology. While many spider species depend on tactile signals, such as vibrations transmitted through their webs, the utilization of airborne sound waves signifies a more advanced sensory adaptation. This discovery provokes questions about whether other spider species might also incorporate sound into their hunting techniques.

Moreover, the study brings to light the remarkable sensory abilities of spiders, which are often undervalued due to their tiny size. Grasping how spiders assess and engage with their surroundings could inspire advancements in fields such as robotics, where researchers are investigating bio-inspired designs for sensory systems and movement mechanics.
