Apollo 19 on approach to the unknown Soviet module

You could cut the tension with a knife. Mission Control is furiously chewing gum, like only a man whose recently been told he's not allowed to smoke in here can. The screen is showing mostly static, but there's enough visibility to see that it's definitely a Soviet module that the Apollo 19 mission is approaching.

Albertson, a young guy of about 22, comes in with a couple binders. "I've got those mission briefs, sir." "Great, great. Chaffee is almost close enough to read the insignia, and then we can figure this crap out." Another phone rings. He ignores it. This mission is screwed up enough without some white house bureaucrat breathing down his neck.

Chaffee's radio signal lights up. "I'm close enough to read the markings. It looks like it's C-O-Ю-З... 2. Over." and a burst of static.

Albertson drops a binder on the floor, the sound making everyone jump, like the Space module a hundred miles over their head might jump out and bite them. Control spots the right binder among the ones still perched on the desk, and grabs it himself.

"Here it is. Soyuz 2, launched back in '68, unmanned. It was supposed to be docked with Soyuz 3, but they gave up and the mission was a failure. Says here that it deorbited 28th of October, 1968. Huh..."

He looks up at the big clock on the wall. It's 9:18 AM, 3rd of July... 1972.

He motions to Stevenson. "Give him the go-ahead. He should know how to open the hatch, we covered this in training." He zones out as Stevenson relays the information. What in the Sam Hill is a Soviet rocket doing in lunar orbit, nearly four years after the blasted thing is supposed to have landed? Did the commies cover up what they were really doing with this rocket? Is his information wrong? Is the damn CIA lying to them again?" and he reaches into his shirt for a pack of smokes that isn't there, for about the 14th time today. He's shaken back to reality by the image showing up on the screen: There's a Krechet-94 spacesuit in the module. There's only one reason a spacesuit would be in an "unmanned" module... this mission wasn't as unmanned as everyone says.

On the screen, Chaffee is reaching into the cramped pod. The suit's sun visor is down, thankfully, he's happen for one less scare today. Chaffee is looking at the suit's indicators, but they're all blank. If someone was alive in there... they aren't anymore. He fumbles with the bottom of the helmet's gold-colored visor, and Control vaguely hears Stevenson relaying to Chaffee that there should be two plastic clips by the bottom which can be used to raise the sun visor. Chaffee gets it, and slowly raises the visor. The death's head, the smiling skull... it's always an almost comical image, even when you rationally know that a skeleton is the result of a living and breathing person who has died and decayed. Control saw plenty of dead bodies back in the war, but usually they weren't this far gone.

Chaffee cuts in on the mic, saying the obvious. Yep, Houston, if you can't see this... it's a skeleton. He says he'll check the uniform for a name. Behind Control, Albertson finally stands back up and ends up dropping the binder all over again, and this time even more people jump. "My god!" he nearly shouts. Control needs a cigarette more than ever.

Albertson peers past Control at the screen. "The Soviets... were sending skeletons into space?"

Control tells Stevenson to take over, he needs to make a call. It's a lie, there's no call, he's just not going to make it through today without a smoke break. And as for Albertson... "Albertson, get the hell out of here. You're too damn stupid to be working at NASA. No, they didn't launch skeletons, you complete... GAH."

The mission carries on. Control gets his cigarette. Albertson goes off to be a fool somewhere else.

By Michael J. Peluso & E. Wesley Ely

Neurocognitive symptoms, including an impaired ability to process and memorize information, are among the most common and debilitating manifestations of long COVID, a disease experienced by as many as 400 million people worldwide, by one recent estimate (Z. Al-Aly et al. Nature Med. 30, 2148–2164; 2024). These symptoms, which can develop alongside those resulting from diseases of the lungs, heart and other organs, affect patients’ everyday functioning for months or even years following COVID-19. Matthew Fitzgerald, a 28-year-old former engineer at Tesla, described his long-COVID-related impairment during a clinic visit: “I’m a shell of myself. My physical issues aren’t half as bad as my brain problems. You can say brain fog, but that doesn’t come close to doing it justice.”

Extreme cases of long COVID stand out — authors who cannot write; nurses who fear making a medical error — but symptoms for most people are more insidious. Many long-COVID patients have neurological problems that meet the criteria for what would normally be considered age-related mild cognitive impairment, or mild to moderate dementia.

Over the past 30 years, US$42.5 billion have been spent on Alzheimer’s research, with limited progress. A decade ago, in part owing to the discovery of neurocognitive symptoms among younger, previously healthy people with complex illness in the intensive care unit, the US National Institutes of Health (NIH) designated a category known as Alzheimer’s disease and related dementias (ADRD) to describe neurological conditions that rob people of their memory and personhood. There is now ample evidence that both older and younger people with long COVID and other infection-associated chronic conditions are at risk of developing ADRD.

As a result, the NIH and other institutions around the world have begun to expand the scope of dementia research to include long COVID under the funding umbrella of ADRD. We serve as co-investigators on a soon-to-launch National Institute on Aging-funded phase III trial to test whether baricitinib, an immune-modulating medication, can improve symptoms of patients with ADRD from long COVID. We hope that this and similar work will open the door for studies of other infection-associated chronic conditions, including myalgic encephalomyelitis/chronic fatigue syndrome and post-treatment Lyme disease.

Brain studies of COVID patients have been among the most revealing science to emerge from the pandemic. Patient scans reveal structural changes, such as in regions near the olfactory tracts and in specific areas of the blood–brain barrier, a membrane that protects the central nervous system from blood-borne toxins and pathogens. Signs of inflammation are sometimes present, and viral remnants have been found in brain specimens of people who died.

Much remains unknown about how long COVID develops and can be treated, but research on the interplay between our immune and nervous systems could provide clues. Scientists have identified how vagal neurons, which connect the brain to the rest of the body, can relay information about pathogens to the brain stem by increasing or dampening the immune response, for example (H. Jin et al. Nature 630, 695–703; 2024). Many researchers have hypothesized that abnormalities in vagal signalling, potentially set off by the SARS-CoV-2 virus, can drive long COVID.

Considering that long COVID affects more than 5% of people infected with SARS-CoV-2, and the risk that some of these patients will develop a rapidly acquired ADRD, there now exists a critical mass of people to study in this category. Vast resources will be needed to untangle how SARS-CoV-2 infection causes long COVID and how it might be prevented and treated. This line of research could have major implications for autoimmune diseases, in general, and neuro-inflammatory conditions, in particular.

Funding organizations are beginning to respond. Beyond the NIH’s US$1.15 billion RECOVER initiative to support long-COVID research, institutes within the NIH are increasingly supporting studies of neurologic long COVID. Major funders in Europe and elsewhere are also stepping up. But more commitments are urgently needed. With sustained investment in long-COVID research, there is enormous potential to inform future directions in ADRD — an area that in the coming years will contend with rapidly escalating patient numbers that are expected to reach 139 million globally in 2050, up from 55 million in 2020. It is crucial that we do not lose momentum.

Function of Brain Stem

Introduction 

The brain stem, often referred to as the “gateway to the brain,” is a vital component of the central nervous system responsible for regulating essential bodily functions and facilitating communication between the brain and the rest of the body. Comprising the midbrain, pons, and medulla oblongata, this intricate structure plays a crucial role in sustaining life and maintaining homeostasis.

1. Regulation of Basic Life Functions

At the core of its function, the brain stem governs fundamental physiological processes necessary for survival, including heartbeat, respiration, and blood pressure regulation. The medulla oblongata, situated at the base of the brain stem, serves as a control center for autonomic functions, such as breathing rate and heart rhythm, by monitoring sensory input and orchestrating appropriate responses.

2. Conduction Pathway for Sensory and Motor Signals

As a conduit between the brain and the spinal cord, the brain stem serves as a relay station for sensory information from the body to the brain and motor commands from the brain to the body. Nerve fibers ascend through the brain stem carrying sensory impulses towards the brain for processing, while descending fibers convey motor signals from the brain to the spinal cord, coordinating voluntary movements and reflex actions.

3. Integration of Reflexes

The brain stem plays a pivotal role in mediating reflex actions, automatic responses that occur in response to specific stimuli without conscious effort. Reflex arcs involving sensory receptors, afferent nerves, interneurons within the brain stem, and efferent nerves facilitate rapid, involuntary reactions to stimuli, such as withdrawing from pain or adjusting posture to maintain balance, ensuring swift and adaptive responses to environmental changes.

4. Control of Arousal and Consciousness

Crucially, the brain stem regulates levels of consciousness and arousal, exerting influence over wakefulness, alertness, and sleep-wake cycles. The reticular formation, a network of nuclei spanning the brain stem, modulates neural activity to promote wakefulness during periods of stimulation and facilitate transitions into sleep or altered states of consciousness, underscoring its pivotal role in regulating the overall level of cognitive awareness.

5. Coordination of Cranial Nerve Functions

Integral to its function, the brain stem houses nuclei responsible for controlling several cranial nerves involved in sensory perception, motor control, and autonomic regulation of organs in the head and neck region. By coordinating the activities of these cranial nerves, the brain stem facilitates crucial functions such as vision, hearing, facial expressions, swallowing, and maintaining cardiovascular and respiratory homeostasis.

6. Facilitation of Postural Control and Balance

Moreover, the brain stem contributes to postural control and balance through its connections with the cerebellum, a structure located at the base of the brain. By integrating sensory feedback from the body and coordinating motor commands, the brain stem helps maintain stability and equilibrium, enabling smooth and coordinated movements essential for navigating the environment safely.

7. Modulation of Autonomic Functions

Additionally, the brain stem modulates autonomic functions, regulating visceral activities such as digestion, urination, and sexual arousal through its influence on the autonomic nervous system. Sympathetic and parasympathetic pathways originating in the brain stem orchestrate physiological responses to stress, rest, and various internal and external stimuli, ensuring adaptive adjustments to maintain internal balance and respond to changing environmental demands.

8. Regulation of Cardiovascular and Respiratory Functions

Furthermore, the brain stem plays a central role in regulating cardiovascular and respiratory functions, ensuring the delivery of oxygen-rich blood to tissues and organs and maintaining optimal gas exchange in the lungs. Through specialized nuclei and reflex pathways, the brain stem modulates heart rate, blood pressure, and breathing patterns in response to physiological needs and environmental cues, safeguarding vital organ perfusion and metabolic balance.

9. Contribution to Neuroendocrine Control

Lastly, the brain stem contributes to neuroendocrine control by serving as a bridge between the nervous system and the endocrine system. Hypothalamic nuclei within the brain stem integrate neural and hormonal signals, regulating the release of pituitary hormones that govern various physiological processes, including growth, metabolism, reproduction, and stress responses, thereby exerting profound influence over systemic homeostasis and adaptation.

Conclusion

In summary, the brain stem embodies the intricate interplay between neural structures and physiological functions, serving as a linchpin of the central nervous system’s regulatory machinery. Its diverse roles encompass vital autonomic, sensory, motor, and integrative functions essential for maintaining life, consciousness, and adaptive responses to internal and external stimuli. Through its complex networks and dynamic interactions, the brain stem exemplifies the remarkable complexity and resilience of the human brain, underscoring its paramount importance in sustaining health, vitality, and cognitive function.

FAQs

1. What is the primary function of the brain stem? The brain stem is responsible for regulating essential physiological functions, including breathing, heart rate, and blood pressure, as well as controlling basic involuntary movements like swallowing and vomiting.

2. How does the brain stem connect the brain to the rest of the body? The brain stem serves as a conduit between the brain and the spinal cord, facilitating the transmission of sensory and motor signals to and from the body’s peripheral nervous system.

3. What are the major anatomical divisions of the brain stem? The brain stem comprises three main regions: the medulla oblongata, the pons, and the midbrain, each with distinct structures and functions contributing to overall neural regulation and coordination.

4. How does the brain stem contribute to consciousness and arousal? The reticular formation, a network of nuclei located throughout the brain stem, plays a critical role in regulating wakefulness, attention, and arousal levels by modulating the activity of cortical and subcortical brain regions.

5. What happens when the brain stem is damaged? Damage to the brain stem can result in profound neurological deficits, including loss of consciousness, impaired vital functions such as breathing and heart rate, and disturbances in sensory and motor control, depending on the extent and location of the injury.

Why would the headlights of your car remain on after the ignition is switched off?

If your car’s headlights remain on after switching off the ignition, it could be due to several factors. Here’s a breakdown of common causes and solutions:

1. Manual Headlight Switch Left "On" • Cause: If the headlight control is set to "On" (not "Auto"), lights may stay on even when the car is off.

• Fix: Turn the switch to "Off" or "Auto." Many modern cars (e.g., Toyota, Honda) have automatic headlights that shut off with the ignition.

2. Delayed Shut-Off (Follow-Me-Home Lights) • Cause: Some cars (e.g., GM, Ford) have a "lighting delay" feature that keeps headlights on for 30–60 seconds after locking the car.

• Fix: Disable this feature via the infotainment settings (e.g., Settings → Lighting → Exit Delay).

3. Faulty Light Sensor (Automatic Headlights) • Cause: A malfunctioning ambient light sensor (e.g., dirty, damaged) may fail to detect darkness and keep lights on.

• Fix: Clean the sensor (usually on the dashboard) or have it recalibrated.

4. Stuck Relay or Wiring Short • Cause: A stuck relay or corroded wiring can keep the headlight circuit energized.

• Test: Swap the headlight relay with another identical one (e.g., horn relay) to see if the issue persists.

• Fix: Replace the relay (cost: $10–$30) or repair damaged wiring.

5. Ignition Switch Failure • Cause: A worn ignition switch may not send a "power off" signal to the headlight circuit.

• Clue: Other systems (radio, power windows) also stay active when the key is removed.

• Fix: Replace the ignition switch (cost: $150–$400).

6. Aftermarket Modifications • Cause: Poorly installed LED kits, alarms, or wiring harnesses can backfeed power to the headlights.

• Example: A miswired trailer hitch or dashcam might keep the circuit live.

• Fix: Inspect aftermarket components and consult an auto electrician.

7. Battery Saver Mode • Cause: Some cars (e.g., Ford, Hyundai) keep lights on temporarily if the battery is critically low.

• Fix: Charge or replace the battery.

8. Software Glitch • Cause: A bug in the Body Control Module (BCM) or firmware can disrupt lighting logic.

• Fix: Update the vehicle’s software at a dealership (e.g., Tesla, BMW).

Troubleshooting Steps

Check the headlight switch position.

Lock the car (many systems shut off lights upon locking).

Disconnect the battery temporarily to reset the system.

Scan for error codes with an OBD2 scanner (look for BCM codes like U0231).

Critical Risks

Dead Battery: Headlights left on overnight can drain the battery (e.g., 55W halogens draw ~5A/hour).

Legal Issues: Some states (e.g., California) prohibit leaving headlights on in parked vehicles.

When to Visit a Mechanic If basic fixes fail, suspect:

Faulty BCM ($500–$1,200 to replace).

Parasitic Drain (use a multimeter to test for >50mA draw after shutdown).

U.S. Navy declares IOC for its new UAS reconnaissance MQ-4C Triton

Fernando Valduga By Fernando Valduga 09/15/2023 - 14:00 in Military, UAV - UAV

The U.S. Navy officially declared the initial operational capability (IOC) of Northrop Grumman Corporation's MQ-4C Triton multi-manned unmanned aircraft on September 14.

Since its Early Operational Capability (EOC) milestone in May 2020, the MQ-4C Triton has operated within the U.S. Navy Pacific Fleet, conducting maritime intelligence, surveillance and reconnaissance (ISR) missions in the area of responsibility of the U.S. Indo-Pacific Command as the Navy's only unmanned, high-altitude, long-lived aircraft.

The MQ-4C Triton, manufactured for use by the U.S. Navy and the Royal Australian Air Force (RAAF), supports a wide range of missions. These include maritime patrol, signal intelligence, search and rescue operations, as well as communications relay tasks.

According to the producer, these aircraft offer persistent surveillance capabilities, assisting in predicting opposing actions and facilitating more effective joint military efforts and enterprises.

Operating at altitudes above 50,000 feet and boasting a 24-hour resistance, the Triton serves as a continuous communications retransmission center, ensuring connectivity between dispersed Navy units, while allowing commanders to operate with a shared operational overview.

“The Triton proved to be invaluable for the maritime patrol and reconnaissance mission in the Indo-Pacific. Now that the system has reached its initial operational capacity, commanders will be able to take full advantage of Triton's powerful set of sensors to detect and stop potential opponents around the world," said Rho Cauley Bruner, director of the Triton program at Northrop Grumman.

"The persistent global maritime awareness is fundamental to deter, or compete and win, our opponents. Triton ensures that we are making informed decisions and operating effectively anywhere in the world," added Captain Josh Guerre, manager of the U.S. Navy's persistent unmanned aircraft systems program.

Northrop Grumman provided the U.S. Navy with a total of five Triton aircraft equipped with multiple intelligence capabilities, with the most recent delivery occurring in June 2023.

How Does Acupuncture Work? An In-Depth Look at This Ancient Healing Practice

Acupuncture is an ancient Chinese healing art that has fascinated and mystified people for over 2,500 years. It involves inserting ultra-thin needles into specific points on the body to treat a variety of health conditions and stimulate the body's self-healing abilities.

But how exactly does acupuncture work? In this comprehensive guide, we'll explore both the traditional Chinese medicine theories and modern scientific perspectives on the mechanisms behind acupuncture. We'll also cover what conditions it may help, what to expect during treatment, its safety profile, and tips on finding a qualified acupuncture practitioner.

A Brief History of Acupuncture

Acupuncture has roots in traditional Chinese medicine (TCM) for over 2,500 years. The general theory is that health depends on the proper flow and balance of qi (vital energy) through pathways or meridians in the body.

Illness or dysfunction occurs when there's an imbalance or blockage of qi flow. Inserting ultra-thin needles into strategic points along the meridians is believed to restore proper energy balance and flow, thus treating disease.

While the concepts of qi and meridians seem mystical, modern researchers have worked to explore the science behind acupuncture's effects. Let's take a closer look at some of the ways acupuncture may work and the evidence behind its use.

Proposed Mechanisms: How May Acupuncture Work?

Over 20,000 studies have explored acupuncture, and several mechanisms have been proposed to explain its therapeutic effects. However, the exact processes behind acupuncture remain only partially understood.

Here, we'll cover some of the leading theories on the complex ways acupuncture stimulation interfaces with the body on a physical and neurological level:

Central Nervous System Effects

One of the most well-researched mechanisms is acupuncture's ability to trigger activity in the central nervous system. Inserting needles at specific points activates sensory nerve fibres, which relay signals to the spinal cord and brain.

This nerve stimulation prompts the central nervous system to release natural chemicals and hormones like endorphins, serotonin, dopamine and oxytocin. These compounds can block pain, regulate mood and emotions, reduce inflammation, and more based on what areas of the brain or body are activated.

So, in simple terms, acupuncture leverages the communication network of the nerves to promote physical and mental wellbeing via chemical responses.

Local Tissue Effects

On a local level, acupuncture needle stimulation causes various tissue-level effects near the site of insertion. Research shows it can increase blood flow and oxygenation, activate connective tissue through mechanical coupling, and regulate local inflammation or swelling.

This helps explain why acupuncture applied in one specific body region can alleviate pain or problems at that body part. For example, needles are inserted into the lower back to treat chronic back pain.

Autonomic Nervous System Regulation

The autonomic nervous system (ANS) controls key involuntary functions like heart rate, breathing, digestion, and metabolism. Acupuncture has been shown to balance the ANS by modulating the activity of the sympathetic and parasympathetic branches.

This effect on ANS function may clarify why acupuncture can benefit conditions tied to the cardiovascular, digestive, reproductive and other systems.

Changes in Brain Chemistry and Function

Emerging research shows acupuncture can prompt wider changes in brain activity and chemistry by promoting neuroplasticity - the brain's ability to structurally adapt and rewire itself. Acupuncture may support beneficial neuroplastic changes that bolster overall brain health.

Placebo Effects

Lastly, the placebo effect likely plays some role as well. The simple belief that acupuncture will provide relief can activate self-healing processes tied to the mind-body connection. However, many studies indicate acupuncture has more substantial effects beyond just placebo.

Now that we've covered some potential mechanisms behind acupuncture, next we'll look at the wide range of health conditions it may benefit.

Health Conditions Acupuncture May Help

Acupuncture has been studied for over 50 different health problems, making it one of the most versatile complementary medicine approaches available today. Here we cover some of the main conditions it may help:

Chronic and acute pain - One of acupuncture's most well-proven uses, backed by abundant research, is alleviating numerous types of pain, including low back pain, neck pain, osteoarthritis, surgery-related pain, and headaches. It's widely embraced as a non-drug option for pain management.

Nausea and vomiting - Multiple studies confirm the ability of acupuncture to control nausea and vomiting tied to surgery, chemotherapy, or morning sickness during pregnancy. Specific wrist acupoints are routinely used.

Reproductive issues - Fertility challenges, menstrual disorders, and symptoms tied to menopause or PCOS are common applications for acupuncture. It may support better reproductive outcomes when done alongside fertility treatments.

Mood disorders - Via effects on brain chemistry, acupuncture can help relieve anxiety and depression, regulating emotional health by lifting mood and outlook.

Digestive problems - Issues like IBS, constipation, nausea and bowel irregularities may improve with acupuncture sessions targeting digestion-related acupoints.

Inflammatory conditions - The regulating effects acupuncture has on inflammation makes it useful for arthritis, asthma, skin conditions and autoimmune issues, according to emerging research.

Insomnia and fatigue - Studies indicate acupuncture can regulate sleep, energy and stamina when these are impaired, helping to treat exhaustion.

Addictions - Early research has explored acupuncture for quitting smoking, alcoholism, and drugs. The calming effects it has may curb cravings and anxiety.

This list just skims the surface of what health problems acupuncture may address either directly or as an adjunct therapy. Our understanding of its therapeutic potential and range of applications continues expanding as research continues.

What to Expect During Acupuncture Treatment

If you decide to try acupuncture for pain relief or other issues, here's a quick overview of what typically takes place during a session:

Initial consultation - You'll discuss your health concerns and symptoms, and your acupuncturist will conduct an exam checking your pulse, tongue, medical history and any problematic areas. This guides your customized treatment plan.

Needle insertion - You'll lie down, sit or sometimes even stand as your provider inserts sterile, single-use, ultra-thin needles. Depth varies from just touching the skin to a couple of inches deep into the muscle. Most feel no or minimal pain.

Needles left in place - Needles remain in strategic points anywhere from a few minutes to 30 minutes, with most people feeling minor sensations like tingling or dull pressure around the sites.

Number of treatments - A health issue you've had for a long time, like chronic lower back pain, may need 1-2 sessions per week for two months. More acute conditions resolve faster - for example, 8-12 sessions helping postoperative pain.

Follow-up and lifestyle advice - Discuss progress with your acupuncturist during and after finishing treatments. They can suggest diet, exercise, and stress relief tips.

So, in a nutshell, a typical acupuncture session involves targeted insertion of tiny needles just under the skin's surface at specific anatomical locations indicated for the health problems you want to address.

Is Acupuncture Safe? What Are the Risks?

When practised by a professionally trained and registered acupuncturist, this needling technique is widely regarded as extremely low-risk and safe for most people. However, some risks include:

Infection (rare with the use of sterile disposable needles)

Nerve injury or organ puncture with very deep needling

Increased bleeding risk if you have a bleeding disorder or take blood thinners

Mild side effects like bruising, soreness, or tiredness for a day after treatment are relatively common.

To reduce risks, always confirm your acupuncturist has proper credentials and training and uses single-use disposable needles. Alert them to any medical conditions you have or medications you take, as certain issues require extra precautions.

While largely safe compared to drug therapies, acupuncture isn't risk-free - but adverse events occur very rarely with competent practitioners.

How to Choose an Acupuncturist: Certification and Costs

With acupuncture growing more mainstream, an explosion of practitioners now offer it. However, credentials, competency levels, costs, and accepted insurance coverage vary greatly.

Here are a few quick tips on finding a skilled, certified acupuncturist in your region:

Confirm proper registration - Look for practitioners on a professional register, such as the Association of Acupuncture Clinicians.

Check ranges costs - Sessions average £45-£95+ throughout the UK, with coverage through many major insurance plans but also many exclusions. Confirm before your visit.

Look into practitioner's experience - Search online reviews and profiles. Don't hesitate to ask pointed questions before committing to more extended treatment. Finding the right acupuncturist for your needs is key.

 

The Takeaway: A Versatile Complementary Therapy Backed by Science

In summary, acupuncture leverages very fine needles inserted into specific anatomical points to stimulate nerve pathways and trigger healing responses - reducing pain, regulating organ function, curbing nausea, lifting mood and more based on which points get activated.

While some scepticism and mystery still surround this ancient needling practice, an increasing body of research points to its usefulness as an adjunct treatment modality for all kinds of health problems.

So, if you're dealing with chronic back or neck discomfort, wrestling with anxiety/depression, or battling fatigue related to autoimmune issues or cancer care, acupuncture is worth considering.

What Is PLC and SCADA? 2025 Beginners Guide

In the modern industrial world, automation is key to ensuring efficient, reliable, and safe operations. Two of the most important technologies behind industrial automation are PLC (Programmable Logic Controller) and SCADA (Supervisory Control and Data Acquisition). These systems are widely used across various industries, including manufacturing, power generation, oil and gas, water treatment, and transportation. This guide provides a clear understanding of what PLC and SCADA are, how they function, and how they work together to streamline industrial operations.

Understanding PLC: The Core of Industrial Automation

A Programmable Logic Controller (PLC) is a rugged digital computer designed specifically for controlling industrial machines and processes. It replaces traditional relay-based control systems and offers flexibility, reliability, and ease of programming.

PLCs are used to automate repetitive tasks. They receive input signals from sensors, process those signals according to a programmed logic, and then trigger appropriate outputs. These outputs can be used to control motors, solenoids, alarms, or other machinery.

One of the main advantages of PLCs is their ability to withstand harsh industrial environments. They are resistant to vibration, electrical noise, extreme temperatures, and dust, making them ideal for use in factories and processing plants.

Components of a PLC System

A basic PLC system includes the following components:

CPU (Central Processing Unit): The brain of the PLC that executes the control logic.

Power Supply: Provides the necessary voltage to the PLC system.

Input/Output Modules: Interface with field devices like sensors and actuators.

Programming Device: Used to write and transfer the logic to the CPU.

Communication Ports: Allow the PLC to connect with SCADA or other PLCs.

Introduction to SCADA: Centralized Monitoring and Control

While PLCs perform local control, SCADA (Supervisory Control and Data Acquisition) provides centralized supervision. SCADA is a software-based system that monitors and controls industrial processes from a central location.

SCADA systems collect data from PLCs and other control devices, display it in a user-friendly graphical format, and store it for future analysis. Operators can monitor equipment status, receive alarms, and send control commands from a SCADA interface.

SCADA is essential in large-scale operations where physical presence at every machine or sensor is not feasible. It allows industries to maintain control over complex systems spread across multiple locations.

Key Features of SCADA Systems

Real-Time Data Acquisition: Gathers data from field devices continuously.

Graphical User Interface (GUI): Displays process visuals for operators.

Alarm Management: Notifies operators of abnormal conditions.

Data Logging and Reporting: Stores historical data for audits and performance evaluation.

Remote Control: Enables operators to control equipment from a distance.

How PLC and SCADA Work Together

In most industrial setups, PLCs are responsible for direct control of machinery. They process sensor data and control outputs based on pre-defined logic. SCADA, on the other hand, acts as a higher-level system that collects data from multiple PLCs, analyzes it, and presents it to operators.

For example, in a water treatment plant, PLCs might control individual pumps and valves, while SCADA provides a dashboard showing water levels, chemical dosages, and system status in real-time. If there is a problem, SCADA alerts the operator, who can then take corrective action remotely.

Applications of PLC and SCADA

The combined use of PLC and SCADA systems is common in many sectors:

Manufacturing: For managing automated assembly lines.

Power Plants: For monitoring turbines, generators, and safety systems.

Water Treatment: For controlling pumps, valves, and chemical dosing.

Oil and Gas: For pipeline monitoring, storage management, and leak detection.

Transportation: For traffic signal control and railway automation.

Benefits of Integrating PLC and SCADA

Improved Efficiency: Automation reduces human error and increases throughput.

Remote Monitoring: Operators can control systems from central control rooms.

Reduced Downtime: Quick response to system failures minimizes interruptions.

Data-Driven Decisions: Real-time and historical data support informed planning.

Cost Savings: Optimized operations lower operational and maintenance costs.

Conclusion

PLC and SCADA systems are foundational technologies in industrial automation. PLCs handle the core control functions at the equipment level, while SCADA provides real-time monitoring and centralized management. Together, they create a powerful system that improves reliability, safety, and efficiency in complex industrial environments.

As industries continue to evolve with Industry 4.0 and smart technologies, the integration of PLC and SCADA will become even more critical. Understanding these systems is essential for engineers, technicians, and anyone aspiring to work in the field of automation.

Open source 24-channel USB high-voltage driver

When it comes to automation and control systems, there's often a need for multiple digitally controlled output terminals with high-voltage handling capabilities. Many existing modules are bulky, expensive, or require numerous additional components to function. To address this gap, I've developed a fully open-source, USB-controlled 24-channel high-voltage driver. This device provides precise, flexible control in a compact and user-friendly package. The project is open hardware, released under the CERN-OHL-W license, ensuring transparency from hardware schematics to firmware code. The driver module communicates via USB using a simple virtual COM port, eliminating the need for special drivers and complex setups.

At the core of the system are three TPIC6B595 shift registers, each supplying eight open-drain outputs that can handle up to 50V and sink currents of up to 150mA per channel. These registers are daisy-chained to achieve a total of 24 outputs. The outputs are designed for low-side switching and include integrated clamping diodes, making them suitable for driving inductive loads such as relays and solenoids. Data is clocked into the registers through serial input from a microcontroller, allowing for fast and reliable state updates across all channels with just a few lines of code.

The logic and communication for this module are managed by the STC15W204S microcontroller, a cost-effective yet powerful 8051-based MCU with enhanced UART performance and an integrated oscillator. This chip is paired with a CH340N USB-to-UART bridge, which presents the device as a standard virtual COM port to the host PC. Upon connection, the microcontroller listens for a set of AT-style commands sent over the serial connection. These commands are straightforward and user-friendly, for example, "ON=65280" activates the middle 8 outputs, "CLR" turns off all channels, and "VER" retrieves the firmware version. Additionally, there is a command to save the current output state to the built-in EEPROM, enabling the system to restore its output to a known state after power cycles. This interface design is perfect for scripting, automation, or integration with software tools such as Python, LabVIEW, or custom control GUIs.

The PCB is designed using KiCad and features a 2-layer layout measuring 75.25mm × 33.75mm. It includes 2.54mm pitch headers for output connections and is equipped with a USB Type-C connector. Power can be supplied through either USB or an external regulated 5V source, which can be selected via onboard jumper settings. The layout ensures clean signal routing and minimizes crosstalk or interference, even when switching high-voltage loads. Careful decoupling and protection components provide robustness for real-world applications.

The PCB for this module was fabricated by PCBWay, who generously sponsored this project. PCBWay offers high-quality PCB manufacturing and assembling services. Also, they offer CNC and 3D printing services. The PCB of this module is available to order from PCBWay. Check out the PCBWay website for its manufacturing capabilities and pricing.

The firmware for the STC15W204S is written in C using SDCC. It is easy to expand the command set, introduce new communication modes, or add timed control logic as needed. The current implementation allows full 24-bit output control using a base 10 numerical mask, making it both scriptable and human-readable. Thanks to the preloaded bootloader of the STC15W204S, firmware updates can be performed through the same serial interface. Details about this process are covered in the project documentation. Like the hardware, the firmware is released under the MIT License and is available in the project repository.

The system has been tested with a variety of 12V and 24V inductive and resistive loads, including relay banks, solenoids, and LED arrays. Since the outputs are open-drain, external voltages up to 50V can be safely switched on each channel making it ideal for a range of industrial, laboratory, or artistic applications. Output timing is reliable, with clean edge transitions observed during scope testing, and no signal integrity issues even during full 24-channel toggling. It is recommended to use individual heatsinks for the driver ICs when driving high-current inductive loads with this module. While the printed circuit board has heat transfer traces, the addition of individual heatsinks can increase the durability of the module.

Potential use cases for this module include automated test benches, home automation systems, signal routing for instrumentation, nixie tube multiplexing, and other high-voltage control tasks. The command-based protocol makes it easy to script operations or integrate this module into a larger system.

For those who wish to explore the schematics, command protocol, design rationale, and usage examples in greater depth, I have published comprehensive documentation and resources in the project wiki. This includes detailed assembly instructions, firmware flashing guidance, and tips on customizing the firmware for enhanced functionality.

All source files - including schematics, PCB layout, firmware code, and the bill of materials - are freely available at https://github.com/dilshan/24ch-usb-high-voltage-driver.

Crown of Toxins: A Scientific Analysis of Slowking’s Neurochemical Symbiosis

Introduction

Among Pokémon, few transformations are as biologically radical as Slowking — an evolution born not of strength, but of neurochemical transfiguration. In this form, a Slowpoke becomes something more than itself: a conscious vessel for a parasite's toxin, crowned with insight and clad in symbiotic elegance.

This article explores Slowking’s unusual anatomy, parasitic relationship with Shellder, the mystery of its red psychic organ, and the function of its vibrant neck frills — all grounded in comparative zoology and speculative xenobiology.

A New Kind of Symbiosis: Toxin as Enlightenment

Unlike Slowbro, in which Shellder clamps the tail and suppresses neural function, Slowking’s Shellder attaches directly to the head, embedding into the outer cranial tissue.

This creates a uniquely inverted parasitism:

Shellder’s neurotoxin, instead of dulling the host, stimulates the brain.

The toxin likely alters neurotransmitter sensitivity and synaptic plasticity, promoting:

Memory consolidation

Abstract reasoning

Self-awareness and speech

Biological Parallel: Some real-world compounds (e.g., psilocybin, DMT) create heightened cognitive states by altering serotonin pathways — mimicking the mental boost seen in Slowking.

The Red Orb: Psionic Interface or Neurocrystal?

Mounted on the Shellder’s crown is a red gem-like structure, found in many Psychic-type Pokémon. It likely functions as:

A bioelectromagnetic organ amplifying brainwave coherence

A psychic relay, enabling extrasensory perception or telepathy

A focus for psionic discharge or consciousness anchoring

Speculative Inspiration: The electroreceptive ampullae of sharks, or the electrical fields used by knife fish, offer real-world analogues for energy-sensing organs.

The Neck Frill: More Than Decoration

Slowking’s neck frill — a broad, colorful collar — likely serves multiple roles:

Venom Buffer: Acts as a reservoir or filtration structure for Shellder's toxins.

Thermal Regulation: High surface area for cooling the blood flowing to its now hyperactive brain.

Warning Signal: Bright coloration warns of its chemical and psychic danger.

Sensory Amplifier (speculative): May enhance or stabilize psionic output through vascular or bioelectric pathways.

Real-World Analogy: The cobra’s hood, the frill-necked lizard, and the parotoid glands of toads all combine signaling with defensive biology.

Behavioral and Physiological Adaptations

Posture: Fully bipedal, with an erect stance that shifts its center of gravity forward — likely due to the added mass of Shellder.

Speech and Memory: In the anime and select Pokédex entries, Slowking is capable of human language, suggesting:

Advanced frontal cortex development

Neural enhancement of speech centers (akin to Broca’s/Wernicke’s areas in humans)

Cognition: Unlike Slowbro’s sedate sluggishness, Slowking is alert, wise, and deliberate — reflecting its chemically altered neuroanatomy.

The Evolution of the Parasite

Shellder’s role is now inert:

No longer feeding, it acts as a living injector, constantly feeding low doses of its neurotoxin into Slowking’s brain.

It is biologically closer to a neural implant than an active organism.

The red orb may be bioengineered by Shellder through evolutionary pressure — a shared organ benefiting host and parasite.

Trajectory: This marks a transition from parasitism → mutualism → organ graft.

Conclusion: A Creature of Enlightened Parasitism

Slowking is the embodiment of biological irony — a creature whose intellect blossoms through venom, whose crown is a parasite, and whose thoughts are sharpened by the sting of symbiosis.

It draws from deep real-world analogues:

Neurotoxin modulation

Bioelectric enhancement

Warning coloration

Endoparasitic control

But no single real animal mirrors it fully. It is a fictional culmination of neurobiology, evolution, and symbiotic transformation — a creature that stands not as a victim of its parasite, but as its cerebral heir.

[sngl-led-auto-lights]

Why do most modern vehicles with LED lighting (brake, running, interior, headlight, etc.) still use incandescent (filament) bulbs in the turn signals?

Modern vehicles increasingly use LED lighting for most functions (headlights, brake lights, b), but many still rely on incandescent (filament) bulbs for turn signals. This design choice is driven by a mix of technical, regulatory, and economic factors:

1. Thermal Cycling & Flasher Circuit Compatibility

Turn signals cycle on/off frequently, creating rapid thermal expansion/contraction. • Incandescent filaments handle this stress better than early LED designs, which suffered from solder joint fatigue.

Flasher relays are designed for the resistance of incandescent bulbs (~6–20Ω). LEDs (≈1–5Ω) can cause "hyper-flashing" (rapid blinking) unless a load resistor or CANbus-compatible flasher is added.

2. Regulatory Requirements

SAE/DOT/ECE Standards: Many regulations mandate minimum luminous intensity (e.g., 200–300 candela for turn signals). • Incandescent bulbs naturally meet these thresholds with simple optics. • LEDs require precise engineering to avoid glare or insufficient brightness.

Amber Color Compliance: Some regions (e.g., EU, Canada) require amber turn signals. • Incandescent bulbs with amber lenses are cheaper than white LEDs + phosphor coatings.

3. Cost-Effectiveness

Bulb Replacement Costs: Turn signals are used less frequently than headlights, reducing the longevity advantage of LEDs. • Example: A standard 3157 incandescent bulb costs $3–$5, while an LED equivalent is $10–$20.

Simplified Circuitry: Incandescents work with existing flasher relays, avoiding the need for CANbus decoders or PWM controllers.

4. Heat Management

Incandescent bulbs generate 360° omnidirectional light, which is easier to diffuse through traditional reflectors.

LEDs emit directional light, requiring complex optics (e.g., TIR lenses) to meet beam pattern regulations.

5. Consumer Expectations

Hyper-flashing Perception: Drivers associate rapid blinking with a "blown bulb," even though LEDs can function correctly with updated flashers.

Warm Color Temperature: Incandescent amber (2,200K) is perceived as more "natural" than LED amber (6,000K with filters).

6. Market Segmentation

Luxury brands (Audi, BMW, Mercedes) often use full LED turn signals as a premium feature, while economy models retain incandescents to keep costs low.

Emerging Solutions

Hybrid Systems: Some vehicles (e.g., 2023 Ford F-150) use incandescent bulbs for turn signals but LEDs for brake/running lights.

Advanced LED Drivers: Newer PWM-controlled LEDs mimic incandescent resistance (~6Ω) to avoid hyper-flashing.

Regulatory Shifts: Updated UNECE R148 standards now allow LED turn signals, accelerating adoption in Europe.

Why the Shift is Slow Factor Incandescent Advantage LED Challenge Cost $0.50–$2 per bulb $5–$15 per bulb + circuitry Regulatory Compliance Plug-and-play with existing laws Requires re-engineering optics Durability Handles thermal cycling Early LEDs failed under rapid on/off Consumer Preference Familiar warm color Perceived as "harsh" or "cheap"

Future Outlook By 2025–2030, LED turn signals will likely dominate as:

Costs drop with mass production of LED modules.

Regulations adapt to LED-specific standards (e.g., UNECE R148).

Hybrid incandescent/LED bulbs (e.g., Sylvania ZEVO) bridge the transition.

For now, incandescent turn signals persist as a pragmatic compromise between performance, cost, and tradition.
