In the face of rising suicide rates, a leading cause of death globally, a powerful yet straightforward intervention has been discovered: caring letters. Sending regular letters from a caring individual to people at risk of suicide can help them feel connected and remind them that they are cared for, which is crucial in preventing suicide.

In a study conducted between 1969 and 1974 in San Francisco, psychiatric hospitals admitted over 3,000 people for depression or suicidal tendencies. Psychiatrist Jerome Motto and statistician Alan Bostrom spearheaded an initiative where some 843 of these patients were randomly assigned to one of two groups after they were discharged from the hospital.

In what was designated as the “contact group”, patients received periodic handwritten letters from a healthcare professional who had earlier interviewed them. These letters were not medical in nature, but rather expressed concern, care, and a desire to stay in contact. An example of the message was:

“Dear John,

It has been some time since you were here at the hospital, and we hope things are going well for you. If you wish to drop us a note, we would be glad to hear from you.

Best,

Susan”

Patients in the contact group received eight letters in the first year and four letters each year for the next four years, totaling 24 letters over five years. On the other hand, patients in the control group did not receive any letters.

The impact of these caring letters was profound. Two years after leaving the hospital, the time when at-risk patients are most likely to commit suicide, only 1.80% of patients in the contact group had committed suicide, compared to 3.52% of patients in the control group. Furthermore, even 13 years after hospital discharge, patients who had received letters from the hospital still had lower rates of suicide than those who had not.

Why does this work? The hypothesis is that receiving regular letters expressing care and concern helps individuals feel connected to others, a feeling that can be especially important during dark times. About a quarter of patients in the contact group sent back messages of gratitude, expressing how much the letters meant to them.

Perhaps most interestingly, this approach is particularly effective for people who are resistant to traditional medical treatment, often due to the stigma associated with mental illness. By communicating care and concern and creating a sense of social connection without demanding anything in return, caring letters can help these individuals survive the critical period following a psychiatric crisis, when they are most likely to take their own lives.

In conclusion, caring letters are a simple, low-cost intervention that can make a significant difference in the lives of those at risk of suicide. They offer a promising approach for healthcare providers and communities at large to help save lives and combat the global challenge of suicide.

This a very good documentary. I had no idea who he is, but he is now a hero of mine :)

The world of economics can often seem difficult to digest, with complex theories and mathematical formulas. But what if we could explain it with something as simple and universally understood as a burger? In this case, the McDonald's Big Mac. This is where the Big Mac Index comes into play.

What is the Big Mac Index?

The Big Mac Index, first introduced by The Economist in 1986, is an informal but ingenious way of understanding and comparing the purchasing power parity (PPP) between different countries. The concept is based on the theory of purchasing-power parity, the notion that in the absence of transaction costs and official trade barriers, identical goods will have the same price in different markets.

The index uses the price of the Big Mac, McDonald's flagship product, as a common item produced and sold across many countries. The price of a Big Mac is then compared across different countries to determine whether a currency is under or overvalued.

How Does It Work?

Let's break it down with an example. Suppose the price of a Big Mac in the United States is $5, and in the UK it's £4. This would suggest an exchange rate of 1:0.8 (5 divided by 4). Now, if the actual exchange rate is 1:0.75, this would suggest that the British pound is overvalued – it's buying more dollars than the Big Mac Index suggests it should.

It’s important to note that while the Big Mac Index offers a fun and easy-to-understand snapshot of currency valuation, it is not a precise measure. Factors such as input costs, profit margins, and taxes can vary significantly from country to country and are not taken into account in the index.

The Relevancy of the Big Mac Index

Despite its simplicity, the Big Mac Index has maintained its popularity as a teaching tool and discussion starter in economic classrooms around the world. It provides a tangible way to understand purchasing power parity, an essential concept in economics.

Furthermore, the Big Mac Index can serve as a real-world check on more formal measures of PPP. While not accurate enough to guide policy decisions, it can highlight cases where currency value seems out of sync with its relative purchasing power.

Moreover, in recent years, the Big Mac Index has been adapted to reflect more than just currency valuation. For instance, it has been used to compare actual GDP per capita with what one might expect given the price of a Big Mac, helping to highlight disparities in wealth.

Conclusion

The Big Mac Index, while an informal measure, provides a tangible and accessible way to understand complex economic concepts. Despite its limitations, it continues to offer valuable insights into global economic trends, highlighting disparities, and prompting discussions about economic theory and practice. As long as the Big Mac remains a global fast food staple, the Big Mac Index will likely continue to be a relevant tool in the world of economics.

After all, who knew a burger could tell us so much about the world economy?

Remember: a Big Mac isn't just a burger, it's also an economic indicator!

In the realm of sound generation and acoustic technologies, there's a phenomenon that has recently captured the attention of scientists and defense agencies alike – laser-induced plasma sound generation. This technology involves the manipulation of plasma using lasers to create sound, and while it sounds like something out of a science fiction novel, it's very much grounded in reality.

Understanding Plasma Speakers

Before diving into the details of laser-induced plasma sound generation, let's first explore a related technology – plasma speakers. Plasma speakers, also known as ionophones, are a type of loudspeaker that employs electrical plasma to vary air pressure, instead of using a solid diaphragm like in traditional speakers.

In these devices, a plasma arc is created which heats the surrounding air causing it to expand. By varying the electrical signal that drives the plasma – a signal that is connected to the output of an audio amplifier – the size of the plasma varies, which in turn changes the expansion of the surrounding air. The result? Sound waves are created.

Compared to conventional loudspeakers, plasma speakers have several unique advantages. Because the plasma is virtually massless, it lacks the inertia inherent in traditional speaker designs, allowing for exceptional transient response and accuracy even at higher frequencies. However, due to their low mass, they are more effective as tweeters as they are unable to move large volumes of air unless there is a large number of plasma entities.

Enter Lasers

Now that we understand the basics of plasma speakers, let's delve into the fascinating world of laser-induced plasma sound generation. The concept involves using two lasers: one to generate a ball of plasma when it hits the target, and another to modulate that plasma ball in open air. This modulated plasma ball can generate a loud sound, with an intensity as high as 140 dB at the target area, equivalent to the sound of fireworks or a shotgun going off at close distance.

In the future, researchers aim to refine the secondary modulation laser to play audio over the plasma. This could potentially turn the beam into a directed loud speaker. Only the target would be able to hear the audio, opening up intriguing possibilities for defensive applications such as non-violent deterrents.

The Talking Fireball

The concept of a “talking fireball” has also been explored, where lasers are pulsed to modulate the sound produced by plasma to carry coherent speech. This so-called “Voice of God” was once considered to be the stuff of rumors and speculation, but recent developments suggest that it might not be as far-fetched as it once seemed. In 2018, the Pentagon’s Joint Non-lethal Weapons Program released a video of a short-pulse laser creating a talking plasma fireball, signifying that the concept was not entirely theoretical.

Conclusion

While the technology of laser-induced plasma sound generation might seem like it's straight out of a sci-fi movie, it's a testament to the incredible strides we are making in the field of acoustics and sound generation. As researchers continue to refine these techniques, we may soon see these “talking lasers” deployed in a variety of applications, from defense mechanisms to new forms of communication. The future of sound is here, and it's absolutely electrifying.

Here, you can find the in-depth article:

A radical new laser-powered sonic weapon was demonstrated at the “Directed Energy to DC Exhibition”. This weapon utilizes a system with two lasers: one creates a ball of plasma when it impacts the target, and the other modulates this plasma ball in open air. The system functions similarly to a plasma speaker, where plasma acts as a driver for a massless speaker. Currently, the system can generate a deafening crack at the target area, with a measured intensity of up to 140 dB. This is as loud as fireworks or a shotgun firing at close proximity, and could theoretically be used to deter anyone targeted by the beam.

In the future, researchers aim to enhance their secondary modulation laser to the point where it can transmit audio over the plasma. This would enable the beam to function as a sort of directed loudspeaker, potentially useful for defensive applications. Only the target would be able to hear the audio, which might be a recording telling them they have entered a secured area. The idea of a disembodied voice instructing you to turn around could serve as a highly effective non-violent deterrent.

The technology takes advantage of plasma speakers or ionophones, which alter air pressure via an electrical plasma instead of a solid diaphragm. The plasma arc heats the surrounding air, causing it to expand. By modifying the electrical signal that drives the plasma, which is connected to the output of an audio amplifier, the plasma size varies. This, in turn, changes the expansion of the surrounding air, creating sound waves. In comparison to conventional loudspeakers, plasma speakers as members of the family of massless speakers, don't have physical limitations inherent in their design.

However, there are practical considerations for plasma speaker designs. They ionize ambient air which contains the gases nitrogen and oxygen. These gases can produce reactive by-products in intense electrical fields, potentially reaching hazardous levels in closed rooms. The two primary gases produced are ozone and nitrogen dioxide.

The lasers create a plasma by tearing apart molecules in the air, producing a glowing ball of fire in the sky. This plasma ball can be shifted back and forth at high speed by moving the laser beams around the sky. The lasers can be pulsed to modulate the crackling sound produced by the plasma to carry coherent speech.

This could potentially be used for psychological operations, with a seemingly divine voice commanding opponents to flee or surrender. While this technology is possible in the lab, it would be very difficult to produce in the sky. However, in 2018, the Pentagon's Joint Non-lethal Weapons Program released a video of a short-pulse laser creating a talking plasma fireball, suggesting that this project is not complete fantasy.

The phrase “Think of the children!” has long been used as a rallying cry to inspire emotion and action. This appeal to protect the welfare of children is undeniably important in certain situations. However, it can also be manipulated to incite moral panic, often leading to the implementation of policies that can infringe upon personal privacy rights.

The article “Think of the Children” on Wikiless delves into how this emotionally charged phrase is often employed by moral guardians and politicians to provoke fear and panic, creating a perceived threat to children that may not always be based on rational argument or evidence. In the worst-case scenarios, the people raising such alarms may not actually be concerned about children's welfare at all. Instead, they may be using this tactic to deflect blame, rally support, or advance their own agendas.

One of the concerning outcomes of this phenomenon is its potential to erode privacy rights. When fear is invoked about children's safety, it becomes easier for laws to be passed without critical scrutiny, even if those laws are not necessarily effective or good. This approach can, and has been, used to justify invasive policies in the name of protecting children, leading to the erosion of privacy rights for all citizens. The unfortunate truth is that children are more likely to be victimized by someone already in their lives, a fact that is conveniently glossed over during these fear-based campaigns.

The phrase “Think of the Children” also serves as a barrier to understanding and accepting new trends or technologies. Anything that children are doing that adults don't fully understand is often painted as inherently harmful, which can contribute to unnecessary regulation and surveillance.

Understanding the implications of the “Think of the Children” rhetoric is crucial in maintaining a balance between protecting children and preserving privacy rights. It's essential that we remain vigilant against emotional manipulation and ensure that the policies we enact are truly in the best interest of children, without unduly infringing on our privacy rights.

Xenobots are synthetic lifeforms that are designed by computers to perform a desired function and are built by combining different biological tissues. These fascinating constructs are named after the African clawed frog, known as Xenopus laevis. The stem cells used in the creation of Xenobots are derived from this species of frog.

What makes Xenobots truly remarkable is their unique nature. They are a one-of-a-kind organism that is simultaneously a living entity comprised of living cells, and a machine that researchers can program to express specific behaviors.

The creation of a Xenobot is a process that involves carefully orchestrated design and execution. The shape of a Xenobot's body, and its distribution of skin and heart cells, are automatically designed in simulation to perform a specific task. This is achieved through a process of trial and error, known as an evolutionary algorithm.

But the capabilities of Xenobots extend beyond their initial programming. These synthetic lifeforms also possess the ability to self-replicate. They achieve this by gathering loose cells in their environment and forming them into new Xenobots with the same capabilities.

The potential applications of Xenobots are both fascinating and wide-ranging. They could be used to pick up microplastics in the ocean, helping to alleviate the growing problem of plastic pollution. In the medical field, they could be used to carry medicine inside human bodies, providing a targeted approach to drug delivery. There's even the possibility of them traveling into our arteries to scrape out plaque, offering a potential revolution in the treatment of cardiovascular disease.

Xenobots represent a bold step forward in synthetic biology, demonstrating the limitless potential of combining biology and technology.

The 1970s was a time of intense geopolitical tension, with the Cold War in full swing. Against this backdrop, the United States Central Intelligence Agency's Office of Research and Development was working on an ambitious project: the Insectothopter, the first insect-sized unmanned aerial vehicle (UAV) in the world.

The Birth of the Insectothopter

The Insectothopter was a marvel of its time, both in concept and execution. The CIA had developed a miniaturized listening device and needed an inconspicuous way to deploy it. Initially, the idea of a mechanical bumblebee was entertained but discarded due to stability issues. Instead, a dragonfly was chosen as the model for this mechanical insect, thanks to its nimbleness, ability to hover and glide, and the fact that dragonflies are native to every continent except Antarctica, rendering their presence unremarkable in most scenarios.

Hand-painted to resemble a real dragonfly, the Insectothopter was powered by a miniature fluidic oscillator that propelled its wings to provide both lift and thrust. A small amount of propellant produced gas to drive the oscillator, with the excess gas vented out the rear generating additional thrust. Control was achieved through two lasers, one for power and another for steering. The tiny UAV had a 6-centimeter-long body and a 9-cm wingspan, well within the range of an actual dragonfly’s dimensions.

Challenges and Legacy

Despite its innovative design, the Insectothopter faced significant operational difficulties. Even a gentle breeze could blow this 1-gram UAV off course, making control in the unpredictable outdoors a serious challenge. Although it performed well under laboratory conditions, “the ultimate demonstration of controlled powered flight has not yet been achieved,” as noted by the CIA's chief scientist. Consequently, the Insectothopter never flew an actual spy mission, and the project was eventually abandoned.

Today, the Insectothopter is displayed at the CIA Museum, a testament to the ambitious vision of the agency's Office of Research and Development during the Cold War era. Although the museum is not open to the general public, the agency has made photos of the device available online.

The Legacy and Future of Miniaturized UAVs

Although the Insectothopter project was abandoned, the concept of miniaturized UAVs for intelligence collection endured. Dragonflies, due to their unique aerial capabilities, continue to inspire the design of modern UAVs. Toy companies even started marketing radio-controlled robotic dragonflies, which proved popular with both kids and adults, highlighting the public's fascination with this technology.

Today, advancements in technology have seen engineers taking a different approach to building a better robotic dragonfly. A project named DragonflEye involves genetically modifying real dragonflies so that their nervous systems respond to pulses of light and equipping them with a backpack of electronics. This bio-hybrid approach presents a new frontier in UAV technology, but it also raises ethical questions about tinkering with nature and the nature of surveillance.

The story of the Insectothopter is a fascinating chapter in the history of surveillance technology. Although the tiny spy drone never achieved its intended purpose, it paved the way for the exploration of miniature UAVs that continues to this day.

(Note: I attempted to find more recent developments in the field of miniature drone technology, but ran into some technical difficulties. I recommend looking up “RoboBees” and other similar projects for more information on the current state of the art in this field.)

The realm of robotics has always drawn inspiration from the natural world. From the graceful flight of birds inspiring drone design, to the nimble agility of geckos informing the creation of wall-climbing robots, nature has consistently served as a blueprint for some of the most innovative breakthroughs in the field. Now, a new and thrilling development has emerged, one that might initially send a shiver down your spine: reanimated spiders.

Welcome to the world of necrobotics.

Necrobotics is a novel field where researchers have successfully reanimated dead spiders to perform tasks. In a groundbreaking experiment, scientists utilized the corpses of wolf spiders and transformed them into mechanical grippers. But how did they achieve such a macabre feat?

The process involved injecting a syringe into a dead spider’s back and securing it with superglue. Fluid was then pushed in and out of the spider's body, causing its legs to clench open and shut. This hydraulics-inspired method turned the spider into a functional tool, capable of manipulating small objects, from pulling wires out of a circuit board to picking up other dead spiders.

This experiment was inspired by a simple but profound question: Why do spiders curl up when they die? The answer led the researchers down a fascinating path. Spiders, it turns out, are essentially hydraulic creatures. They control the extension of their legs by forcing blood into them. Once a spider dies, it loses this blood pressure, causing its legs to curl up.

Looking ahead, the researchers aim to individually control the spiders' legs, thereby gaining a deeper understanding of their physiology. This knowledge could then be translated into improved designs for other robots. However, this exciting scientific exploration is not without challenges. After hundreds of uses, the necrobots began to show signs of wear and dehydration. To counteract this, future plans involve coating the spiders with a sealant to slow their deterioration.

The potential implications of this research are immense, not only for robotics but also for our understanding of nature's intricate mechanisms. Yet, as with any groundbreaking research, it brings about its own set of ethical questions. How far should we go with bioengineering? Is it acceptable to manipulate life and death in this way? As we stand on the cusp of this thrilling frontier, these questions warrant careful consideration.

Undeniably, the world of necrobotics is as enthralling as it is eerie. Its ability to blend life, death, and technology opens up a plethora of opportunities for the future of robotics, bioengineering, and our understanding of the natural world.
