The evolution of life may have its origins in outer space

Astronomers find signs of complex organic molecules – precursors to sugars and amino acids – in a planet-forming disc.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers led by Abubakar Fadul from the Max Planck Institute for Astronomy (MPIA) has discovered complex organic molecules – including the first tentative detection of ethylene glycol and glycolonitrile – in the protoplanetary disc of the outbursting protostar V883 Orionis. These compounds are considered precursors to the building blocks of life. Comparing different cosmic environments reveals that the abundance and complexity of such molecules increase from star-forming regions to fully evolved planetary systems. This suggests that the seeds of life are assembled in space and are widespread. The findings were published in the Astrophysical Journal Letters today.

Astronomers have discovered complex organic molecules (COMs) in various locations associated with planet and star formation before. COMs are molecules with more than five atoms, at least one of which is carbon. Many of them are considered building blocks of life, such as amino acids and nucleic acids or their precursors. The discovery of 17 COMs in the protoplanetary disc of V883 Orionis, including ethylene glycol and glycolonitrile, provides a long-sought puzzle piece in the evolution of such molecules between the stages preceding and following the formation of stars and their planet-forming discs. Glycolonitrile is a precursor of the amino acids glycine and alanine, as well as the nucleobase adenine.

The assembly of prebiotic molecules begins in interstellar space

“Our finding points to a straight line of chemical enrichment and increasing complexity between interstellar clouds and fully evolved planetary systems.” – Abubakar Fadul, MPIA

The transition from a cold protostar to a young star surrounded by a disc of dust and gas is accompanied by a violent phase of shocked gas, intense radiation and rapid gas ejection.

Such energetic processes might destroy most of the complex chemistry assembled during the previous stages. Therefore, scientists had laid out a so-called ‘reset’ scenario, in which most of the chemical compounds required to evolve into life would have to be reproduced in circumstellar discs while forming comets, asteroids, and planets.

“Now it appears the opposite is true,” MPIA scientist and co-author Kamber Schwarz points out. “Our results suggest that protoplanetary discs inherit complex molecules from earlier stages, and the formation of complex molecules can continue during the protoplanetary disc stage.” Indeed, the period between the energetic protostellar phase and the establishment of a protoplanetary disk would, on its own, be too short for COMs to form in detectable amounts.

As a result, the conditions that predefine biological processes may be widespread rather than being restricted to individual planetary systems.

Astronomers have found the simplest organic molecules, such as methanol, in dense regions of dust and gas that predate the formation of stars. Under favourable conditions, they may even contain complex compounds comprising ethylene glycol, one of the species now discovered in V883 Orionis. “We recently found ethylene glycol could form by UV irradiation of ethanolamine, a molecule that was recently discovered in space,” adds Tushar Suhasaria, a co-author and the head of MPIA’s Origins of Life Lab. “This finding supports the idea that ethylene glycol could form in those environments but also in later stages of molecular evolution, where UV irradiation is dominant.”

More evolved agents crucial to biology, such as amino acids, sugars, and nucleobases that make up DNA and RNA, are present in asteroids, meteorites, and comets within the Solar System.

Buried in ice – resurfaced by stars

The chemical reactions that synthesize those COMs occur under cold conditions, preferably on icy dust grains that later coagulate to form larger objects. Hidden in those mixtures of rock, dust, and ice, they usually remain undetected. Accessing those molecules is only possible either by digging for them with space probes or by external heating, which evaporates the ice.

In the Solar System, the Sun heats comets, resulting in impressive tails of gas and dust, or comas, essentially gaseous envelopes that surround the cometary nuclei. This way, spectroscopy – the rainbow-like dissection of light – may pick up the emissions of freed molecules. Those spectral fingerprints help astronomers to identify the molecules previously buried in ice.

A similar heating process is occurring in the V883 Orionis system. The central star is still growing by accumulating gas from the surrounding disc until it eventually ignites the fusion fire in its core. During those growth periods, the infalling gas heats up and produces intense outbursts of radiation. “These outbursts are strong enough to heat the surrounding disc as far as otherwise icy environments, releasing the chemicals we have detected,” explains Fadul.

“Complex molecules, including ethylene glycol and glycolonitrile, radiate at radio frequencies. ALMA is perfectly suited to detect those signals,” says Schwarz. The MPIA astronomers were awarded access to this radio interferometer through the European Southern Observatory (ESO), which operates it in the Chilean Atacama Desert at an altitude of 5,000 metres. ALMA enabled the astronomers to pinpoint the V883 Orionis system and search for faint spectral signatures, which ultimately led to the detections.

Further challenges ahead

“While this result is exciting, we still haven't disentangled all the signatures we found in our spectra,” says Schwarz. “Higher resolution data will confirm the detections of ethylene glycol and glycolonitril and maybe even reveal more complex chemicals we simply haven't identified yet.”

“Perhaps we also need to look at other regions of the electromagnetic spectrum to find even more evolved molecules,” Fadul points out. “Who knows what else we might discover?”

It's foolish to think that Putin isn't orgasmic over what the Trump administration has been doing to screw America.

Trump and his co-president Elon Musk have now targeted the EPA for revenge and retribution.

Trump, Musk move to oust EPA staff in the Great Lakes region, including dozens responsible for protecting drinking water for 30 million in U.S. and Canada

Trump purged dozens of career officials in the Chicago office during his first term. His latest attempt to cull the workforce is led by billionaire Elon Musk, whose companies Tesla and SpaceX have been fined by the EPA for multiple violations of environmental laws. “Elon Musk wants to turn EPA into every polluter’s ally,” U.S. Sen. Edward Markey, a Massachusetts Democrat, said Thursday at a rally in front of the agency’s headquarters. “He wants to take environmental cops off the beat.” History suggests Musk and scores of other polluters are going to catch a break during the next four years. Water pollution cases filed by the EPA in the Great Lakes region declined during each of the first three years Trump was president, according to an analysis of agency records by the nonprofit Environmental Law and Policy Center. Meanwhile, the number of chronic violators of the Clean Water Act in the heavily industrialized states skyrocketed under Trump, who as a candidate in 2016 vowed to abolish the EPA. [ ... ] More than 8 million people in Illinois get their drinking water from a utility where at least one PFAS has been detected, a 2022 Chicago Tribune investigation found. The discovery of high levels of ethylene oxide pollution led to the closure of a sterilization plant in southwest suburban Willowbrook and prompted a state law requiring another facility in north suburban Waukegan to dramatically reduce emissions.

Trump feels it's his right to make life easy for polluters who have given him and other far right Republicans huge campaign contributions.

States like Illinois can step up enforcement. But they don't have the reach and resources of the federal government. Be prepared to get sicker over the next few years.

Drainback Systems with Advanced Freeze Protection for Solar Water Heating

Drainback systems are a popular and effective solution for solar water heating in cold climates. These systems use a gravity-driven flow to circulate heat transfer fluid between the solar collectors and the storage tank. One of the main advantages of drainback systems is their freeze protection, which helps prevent damage to the system in cold weather by ensuring that the heat transfer fluid is not exposed to freezing temperatures. Advanced freeze protection features in these systems further enhance their ability to operate reliably in winter conditions, providing a highly durable and low-maintenance solution for solar water heating.

Here’s an overview of drainback systems, how they work, and the advanced freeze protection mechanisms that make them ideal for cold climates.

1. How Drainback Systems Work

A. Basic Principle

Drainback systems are designed to automatically drain the heat transfer fluid from the solar collectors when the system is not actively heating water. This is especially useful in freezing conditions, as it prevents the fluid from being exposed to low temperatures in the collectors or pipes.

Fluid Circulation: The system circulates the heat transfer fluid (usually water or an anti-freeze solution) through the solar collectors during sunny periods. The heated fluid rises to the storage tank, where the heat is transferred to the water.

Gravity-Driven Flow: Unlike active solar systems that use pumps, drainback systems use gravity and natural convection to circulate the fluid between the collectors and the tank. When the system is not in use (e.g., during the night or when temperatures drop), the fluid naturally drains back into the storage tank.

B. Fluid Drainage for Freeze Protection

Automatic Drainback: When the system is off, the drainback valve opens, and the heat transfer fluid flows back into the storage tank, leaving the collectors and pipes empty. This ensures that no fluid remains in the system, preventing it from freezing inside the collectors or pipes.

Drainage in Freezing Conditions: The automatic drainage function of the system protects the collectors from freezing damage. If temperatures drop below freezing, the system drains the fluid before it has a chance to freeze, ensuring that the system remains intact and operational.

2. Advanced Freeze Protection Features in Drainback Systems

While basic drainback systems provide effective freeze protection, modern systems are equipped with advanced freeze protection mechanisms that enhance the system’s resilience to extreme cold. These advanced features are designed to provide an extra layer of protection to ensure that the system operates efficiently in freezing conditions.

A. Temperature Sensors for Freeze Detection

Smart Temperature Monitoring: Advanced drainback systems often come with temperature sensors placed in key components of the system, such as the solar collectors, the storage tank, and the fluid lines. These sensors continuously monitor the temperature of the fluid and the system components.

Automatic Freeze Protection Activation: When the system detects that the temperature is approaching freezing levels, the smart control system automatically activates the freeze protection features, such as draining the fluid from the collectors or turning on a backup heating element.

B. Antifreeze Protection Systems

Anti-Freeze Solutions: In regions with extremely cold weather, anti-freeze solutions (e.g., propylene glycol or ethylene glycol) are often used in conjunction with drainback systems. These solutions lower the freezing point of the circulating fluid, allowing it to remain in liquid form even in very low temperatures.

Dynamic Fluid Adjustment: Some drainback systems can automatically adjust the concentration of the anti-freeze solution based on the weather conditions. This helps ensure that the fluid remains in liquid form even during the coldest months of the year.

C. Thermal Buffering and Heat Retention

Insulated Pipes and Storage Tanks: In cold climates, insulating the pipes and storage tank is crucial for preventing heat loss and ensuring that the fluid remains at an optimal temperature. Advanced drainback systems use high-performance insulation materials around pipes and tanks to minimize heat loss.

Thermal Mass in Tanks: Some drainback systems incorporate thermal mass in the storage tank, which helps store excess heat during sunny periods and release it when solar radiation is insufficient. This feature is especially useful in cold weather, as it allows the system to continue providing hot water for longer periods without relying heavily on backup heating.

3. Automatic Drainback Valves and Smart Control Systems

A. Automated Drainback Valves

Function: In a drainback system, the drainback valve automatically opens and closes based on the system's operation. When the system is active, the valve remains closed, allowing the heat transfer fluid to circulate through the collectors. When the system is idle (such as at night or during freezing conditions), the valve opens, allowing the fluid to drain back into the storage tank.

Fail-Safe Mechanism: The drainback valve is designed to operate with a fail-safe mechanism that ensures proper drainage during periods of inactivity. If the valve malfunctions, the system’s smart control system can activate backup protection measures to prevent freeze damage.

B. Smart Control Systems

Freeze Protection Monitoring: Smart control systems are equipped with temperature sensors and programmable settings that allow the system to monitor and adjust operation based on real-time conditions. When cold temperatures are detected, the system can automatically activate freeze protection measures, such as:

Draining the fluid from the collectors.

Activating the backup heating system to maintain water temperature.

Closing the drainback valve when needed to ensure that the system is properly protected.

Predictive Freeze Protection: Some smart systems use weather forecasts and historical temperature data to predict freeze events in advance. This predictive capability ensures that the system is prepared for extreme cold conditions before they occur, preventing potential damage and reducing the risk of costly repairs.

4. Hybrid Systems and Backup Heating Integration

A. Integration with Backup Heating

Hybrid Design: Drainback systems can be integrated into hybrid solar water heating systems, where a conventional backup heating system (e.g., gas, electric, or heat pump) is used to maintain water temperature during extended cloudy periods, snow accumulation, or extremely low temperatures.

Automatic Switching: The smart control system automatically switches between the solar system and backup heating based on temperature and energy availability. This ensures that the system can always provide hot water, even during prolonged periods of low solar radiation.

B. Heat Pump Backup Systems

Heat Pump Integration: In some systems, heat pumps are integrated with drainback systems to provide a highly efficient backup heating solution. Heat pumps work by transferring heat from the air or ground to the water, providing an energy-efficient method of maintaining hot water when solar energy is insufficient.

5. Benefits of Drainback Systems with Advanced Freeze Protection

A. Improved Durability and Longevity

Freeze Protection: The primary advantage of drainback systems with advanced freeze protection is their ability to prevent freeze damage to the system. By ensuring that no fluid is left in the collectors or pipes during freezing conditions, these systems maintain the integrity of the components and significantly extend the lifespan of the system.

B. Reduced Maintenance Costs

Low Maintenance: Since drainback systems are passive and have fewer mechanical parts than active solar systems, they require less maintenance overall. The advanced freeze protection features, such as automated drainage and freeze detection, help minimize the risk of costly repairs due to freezing or snow accumulation.

C. High Efficiency and Reliability

Optimized Efficiency: With the ability to adjust to varying weather conditions, smart control systems optimize the performance of the drainback system, ensuring high efficiency and reliability even in cold weather.

Reliable Hot Water Supply: The combination of solar energy and backup heating ensures that a reliable supply of hot water is available year-round, even in regions with harsh winters.

Drainback systems with advanced freeze protection offer a reliable, energy-efficient, and low-maintenance solution for solar water heating in cold climates. By integrating features like automatic drainage, smart control systems, anti-freeze solutions, and hybrid heating, these systems ensure optimal performance, minimize freeze damage, and provide a continuous supply of hot water throughout the year. Their ability to handle the challenges posed by freezing temperatures, snow accumulation, and low solar radiation makes them an ideal choice for residential, commercial, and industrial applications in colder regions.

Shorter lifespan compared to EPDM or PVC

How Membrane Roofs Stay in Place

Membrane roofs, often used on flat or low-slope roofs, remain secure through specific installation methods engineered to resist wind uplift and external forces. The method chosen depends on the membrane, climate, building structure, and budget. Below are the most common techniques:

1. Mechanical Fastening

This method involves physically anchoring the membrane to the roof deck using screws and metal plates. Fasteners are placed at regular intervals, typically within membrane seams, which are then overlapped to hide and protect them.

Advantages:

Cost-effective

Fast installation

Suitable for various temperatures and weather conditions

Limitations:

Higher potential for air infiltration

It can be extremely noisy during strong winds

It may require more maintenance at seams and fastener points

2. Full Adhesion

In a fully adhered system, installers apply contact adhesive to both the membrane and substrate, creating a continuous and secure bond across the entire roof surface.

Advantages:

Excellent resistance to wind uplift

Watertight seals reduce leaks

Enhances energy efficiency by minimizing air pockets

Limitations:

Requires dry, clean conditions for proper bonding

More expensive than mechanically fastened systems

Adhesive application may extend installation time

3. Ballasted Installation

Ballasted systems involve laying the membrane loosely over the insulation and securing it with heavy materials (gravel, pavers, or river stones). The weight holds the membrane in place and shields it from weather and UV rays.

Advantages:

Simple and fast to install

Very durable with added thermal mass

Easily removable for repairs or roof access

Limitations:

Adds significant weight to the structure

It can be difficult to detect leaks beneath the ballast

Not ideal for high-wind zones or buildings with low load capacity

Additional Membrane Reinforcement Methods

Besides the principal anchoring methods, membrane roofs include several features that enhance their longevity and resistance to uplift and leaks:

Seam Sealing: Seams are critical points in roofing. For TPO and PVC, seams are heat-welded; for EPDM, seams are bonded using rubber adhesive or seam tape. Proper sealing ensures waterproofing and structural integrity.

Flashing: Flashing around roof edges, vents, drains, and penetrations forms a continuous barrier against water intrusion and wind damage.

Edge Reinforcement: Fasteners are often added along roof perimeters and penetrations to secure vulnerable areas and improve resistance during storms or high winds.

Preventing Leaks with Roof Maintenance

Commercial membrane flat roofs are straightforward but still require attention at times. Regular inspections and proactive maintenance can prevent costly damage and extend the lifespan of the entire roof system.

New Image Roofing Atlanta offers commercial roof maintenance programs designed to:

Identify early signs of wear or damage around boots, seals, and flashing

Reapply or repair flashing and sealants

Clear debris that could cause pooling/ponding water

Document roof conditions for warranty and insurance purposes

Schedule preventative maintenance to avoid unplanned downtime or repairs

A well-maintained roof can last significantly longer, and proactive care reduces emergency service costs.

Key Considerations for Adhering Membrane Roofing

Selecting the correct method for adhering membrane roofing systems to substrates depends on multiple variables assessed during planning and design.

1. Roof Structure and Load Capacity:

Not every building can handle the weight added by a ballasted system. Before installation, engineers must evaluate whether the structure can support the chosen method.

2. Climate Conditions:

Regions with high winds or extreme weather require stronger adherence methods, like fully adhered or mechanically fastened systems. Ballasted systems may not be ideal for areas that experience hurricanes.

3. Energy Efficiency Goals:

White membranes (TPO and PVC) reflect sunlight and reduce heat gain, which contributes to energy savings. Fully adhered systems offer better insulation performance by eliminating air gaps.

4. Installation Environment:

Fully adhered roofs require specific temperature and moisture conditions for adhesives to cure properly. Mechanical fastening may be a better choice in colder or damp climates.

5. Maintenance and Accessibility:

If the roof requires frequent access, a ballasted or mechanically fastened system may be easier to inspect and maintain. Fully adhered roofs are best for minimal foot traffic to preserve membrane integrity.

Careful evaluation of these factors ensures not only proper installation but also long-term durability and performance.

Keeping Your Membrane Roof in Place

In this article, you discovered essential information about commercial membrane roofing types (benefits and drawbacks), adherence methods, and maintenance programs.

Membrane roofing systems provide long-lasting, weather-resistant protection when selected and installed. Whether choosing mechanical fastening, full adhesion, or ballast, each method plays a key role in ensuring roof stability.

Failure to understand how secure membrane roofing systems are will leave you paranoid about your roof every time the wind blows.

Boost Fruit Shelf Life with Smart Ethylene & CO₂ Monitoring

Why Gas Monitoring Is Essential in Fruit Ripening

Post-harvest fruit losses are a serious concern for producers and distributors. A major cause? Poor control over ripening gases like ethylene and carbon dioxide. Without real-time monitoring, inconsistent ripening, early spoilage, and major financial losses are inevitable.

Smart ethylene and CO₂ gas monitoring systems, like those offered by ESEGAS, ensure precise environmental control in ripening chambers—leading to better fruit quality, longer shelf life, and fewer losses.

Ethylene: The Ripening Trigger That Needs Precision

Ethylene is the key hormone that controls ripening in climacteric fruits like bananas, avocados, and mangoes. While it’s essential for color and sweetness, too much ethylene or uneven exposure can cause fruit to ripen unevenly, decay early, or lose visual appeal.

ESEGAS ethylene sensors use advanced photoacoustic or electrochemical technologies to provide real-time, continuous data on gas levels inside ripening rooms. This ensures that fruit is exposed to the right amount of ethylene at the right time—improving uniformity and avoiding unnecessary spoilage.

“Precise ethylene control helps every piece of fruit ripen evenly—no more color mismatch or waste.”

CO₂: The Hidden Factor in Controlled Ripening

While ethylene triggers ripening, carbon dioxide (CO₂) helps manage and delay it. When used correctly, CO₂ can slow down ethylene activity, giving operators the ability to control ripening schedules—which is essential for logistics and market timing.

ESEGAS CO₂ analyzers use non-dispersive infrared (NDIR) technology, ideal for detecting subtle gas shifts. This is important because too much CO₂ can lead to off-flavors and tissue breakdown. Proper CO₂ management also prevents mold and microbial growth in high-humidity environments.

Why Choose ESEGAS Sensors?

ESEGAS sensors are built for the real-world challenges of fruit storage—high humidity, fluctuating temperatures, and gas stratification. Their analyzers offer:

High-accuracy detection at low ppm levels

Fast response time for real-time adjustments

Smart calibration and self-diagnostics

Durability in harsh, moist conditions

With IoT-ready features and multiple output options (Modbus, 4–20 mA, RS485), they’re easy to integrate into existing systems.

“With ESEGAS, your ripening room becomes a data-driven environment—responsive, efficient, and reliable.”

Sensor Placement & Maintenance: Small Steps, Big Impact

Correct sensor placement and care are key to getting accurate data. Install sensors at fruit height, away from fans or direct gas jets. In larger chambers, use multiple sensors to avoid blind spots.

ESEGAS sensors offer easy calibration, protective filters, and firmware updates to maintain long-term accuracy.

Conclusion: Ripen Smarter with ESEGAS

Whether you manage bananas, mangoes, or tomatoes, the key to successful ripening lies in gas control. ESEGAS ethylene and CO₂ sensors empower you to maintain perfect ripening conditions, reduce losses, and deliver consistently high-quality produce to market.

"The Unified System: 1970"

A cell. A lung cell. Tobacco smoke swirls by in the spired and foliated channel the cell faces. Its job is to take in oxygen from breath and keep out everything else, and on the whole it does well filtering the usual impurities in air: but this is not a designed mechanism, put together for a function by conscious plan, it is a dumb iteraion of all the features which have proved by trial and error to serve lung cells well in the past. The past did not include deliberately-breathed smoke. We could count an amazing number of different chemicals in the blue-grey vapour snaking through the tissue, altogether too many of which the cell does not know how to exclude. Formaldehyde, acetaldehyde, catechol, isoprene, ethylene oxide, nitric oxide, nitrosamine, the aromatic amines — not to mention the quinones, the semiquinones, the hydroquinones, a whole fanily of polycyclic aromatic hydrocarbons. We are watching for one of these last. Here it comes now, a drifting, tumbling molecule of benzopyrene. It sails into the cell's bulging curtain wall of fats and sticks there, like an insect caught in glue; then, worse, is dragged through, because the fat curtain is spiked here and there by receptors, and one of these has the benzopyrene in its grip. The receptor winches the benzopyrene through the curtain, hand over hand, atom over atom, wrapping it as it comes in a fold of the curtain, and then closing the fold behind it, so that when it reaches the inside, a little fatty envelope buds off from the inner wall of the cell with the benzopyrene sealed inside it. And floats free, into the warm liquid workspace where the body builds its proteins.

But it's all right. The cell has no specific defence against benzopyrene, but it is not defenceless. It has the powerful standard equipment all mammalian cells deploy when foreign bodies turn up where they're not supposed to. The package of fat is a flag, a label, an alert. Detecting it, up comes an enzyme to metabolise the contents. The enzyme munchs the benzopyrene into pieces of epoxide which other bits of the cellular machinery can flush safely away.

This has happened over and over again, every time Sergei Alexeyevich Lebedev lights a cigarette. There are billions of cells in the lungs. Lebedev has smoked thousands of unfiltered Kazbek a day for fifty years. So this has happened thousands of billions of times.

***

Another lung cell. The machines that Lebedev has made all build up their complicated behaviours from absolutely predictable little events, from valves and then transistors turning on and off. Definitely on; definitely off. Without any shading of degree. Without any ambiguity. The machine that makes Lebedev is different. The base layer of its behaviour, from which all the rest emerges, is various and multiple and uncertain. There is no binary simplicity. There is the slow bubble of many chemical reactions all happening at once, each continuing until a task is mostly done, probably done, done enough to satisfy a program which was itself only whittled out of randomness just well enough to get by. The enzyme’s destruction of benzopyrene, for example, only flushes most of it away. A fraction of the epoxides react again with the enzyme and become diol epoxides. That’s what’s happened here; instead of nice, inert, detoxified molecules, we have a version of the same thing which is lacking one electron on one of its atoms, and which consequently yearns to stick to any other molecule which will share an electron with it. The diol epoxides are aggressive gloop. Aggressive? One electron’s worth of electric charge doesn’t tow a molecule very fast through the soupy interior of a cell: it doesn’t send the diol epoxides streaming along at the speed of light like the electrons in a vacuum tube. But it does exert a tiny, persistent pull on them. It draws them along towards molecules they might stick to. It draws them everywhere in the cell, and so it draws some of them towards the cell nucleus, which has another wall of fats around it, but unfortunately is designed to let molecules rather like the diol epoxides in and out on the cell’s ordinary business. The hungry, electron-seeking blob of gloop slips through, and there in front of it are floating twenty-three pairs of tempting targets: the huge, fat, friendly, electron-rich chromosomes of human DNA.

No one in the world in 1970 understands in any detail how they work, and the ignorance is particularly bad in the Soviet Union, thanks to Lysenko. But the chromosomes work whether they are understood or not. The gloop drifts in; and at any and every point along the endless coiled helix where it happens to make contact, the gloop locks on. Where it jostles forward with its missing electron to embrace one of the DNA’s electrons, there’s a little chemical reaction, and the electron in question bonds to both the DNA and the gloop. The gloop is now an ‘adduct’, glued to the helix. But the helix is changed too, by having the blob of tobacco residue stuck to it. At the position where the adduct sits, the information in the DNA has been corrupted. Instead of the G, T, C or A that should be there, in the four-letter alphabet of the genome, it reads as one of the other letters instead. The adduct has written an error into the code.

But it’s all right. In the vast majority of positions along the genome where goo might attach itself at random, altering one letter won’t produce any significant mutation, even if the alteration lasts. The genome is Lebedev’s software, but unlike software written by humans, it is not a set of procedures packed end-to-end, all of which at least purport to do something. It is a jumble of legacy code spread out in fragments through a whole voluminous library of nonsense. Almost always, a random change of letter will either hit some existing nonsense, or turn some sense into new nonsense. And because the chromosomes come in pairs, with a version of every chromosome contributed by Lebedev’s mother floating there opposite a version from his father, if some sense on the version on one side turns to nonsense, the equivalent piece on the other version will go on making sense just fine. Dangerous mutations usually only happen in the rare cases where sense is accidentally turned into different sense. Which is not what has happened here. Here, the arriving molecule has glued itself where it makes no difference at all.

This has happened billions of times.

***

Another lung cell. The soft rainfall of gloop onto Lebedev’s DNA continues. By chance, this particular sticky drop in the statistical rain is one of the small minority that is going to land somewhere that matters. By chance, it is falling onto a stretch of code on Chromosome number 11 which scientists will know later as the gene ras, or hRas. The electrophile noses in; it suckers on; the guanine (G) it has suckered onto on the helix now reads, for all intents and purposes, as cytosine (C). And this time, it happens that changing G to C creates sense, not nonsense, in the code. Ras with a C in it at this specific position is a viable and functional piece of software. But much more of a change is in prospect than there would be if someone substituted a new programme for the one that was supposed to be running in a computer. Human-made software is only an informational ghost, temporarily given possession of the machine and allowed to change 0s to 1s and vice versa. The software of humans, on the other hand, actually builds the hardware it runs on. It creates the machine. So a mutation in the code means a mutation in the body too, if the error endures.

Ras is one of the genes that control cell growth and cell division. In adults, it switches on and off periodically to govern the normal cycle of the cell’s existence. You wouldn’t want it switched on all the time. Foetuses in the womb run ras continually to generate all the new tissue that the Build-A-Human program demands when a human is being first assembled. Otherwise, cell multiplication must happen when, and only when, the body part the cell is in needs a new cell. But it’s the switch that has been altered by having C where G used to be in this mutant version of ras. C instead of G at this one particular point jams the ras gene at ‘on’ – throws the lever for unstoppable growth, and then breaks the lever.

But it’s all right. This copy of ras may be corrupted, but the cell has a failsafe mechanism built into the shape of the DNA molecules. The helix is a double helix. On the other side of the double corkscrew there runs another strand of Gs, Ts, Cs, and As which carries all the information of the genome, only in reverse, like the negative of a photograph or the mould a jelly was turned out of; and the cell, which is used to operating in an environment of small chemical accidents, operates a handy editorial enzyme that moves up and down the chromosomes checking that the two strands remain perfect opposites. The editorial enzyme doesn’t find absolutely all of the changes the adducts gummed to Lebedev’s DNA have made, but it finds most of them, the harmless and the harmful alike, methodically correcting each little mutation. It finds this one. The new C in the mutant version of RAS on one side clashes with the existing C on the reverse side. C against C isn’t a legitimate opposite. A quick editorial snip, and there’s the original G again. Lebedev’s factory settings have been restored.

This has happened millions of times.

***

Another lung cell. There is a way for a blob of goo to cause a ras mutation that persists. The gummy electron-seeking missile has to arrive, and glue G into C in the exact right place, at the exact right moment in the life of the cell when for once the enzyme cannot compare ras to its negative. That is, when the lung cell is already busy dividing into two lung cells. The goo floats in, and finds inside the nucleus a double helix which has been unzipped into two separate strands, each of which is going to grow back into a complete copy of the genome. Of all the random blobs of goo in the random rainstorm, here comes the blob that suckers onto Chromosome 11 in the position to create the always-on version of ras, just as the unzipped halves of Chromosome 11 are waving loose. It’s too late for the editorial enzyme: there’s nothing to correct the mutant C against. Along the strand instead travels a polymerase, a construction enzyme, steadily building out the other half of a new double helix. And when it reaches the C, it obligingly supplies a new counterpart for the other side which is a match, which is a perfect opposite. The corrupted code has reproduced itself. After a while, there are two sets of completed chromosome pairs in the nucleus. They pull away from each other. The nucleus stretches, puckers out like dumb-bells, splits into two as well. Last the outside wall of the cell repeats the split, stretching and pulling and puckering back into a pair of separate fatty spheres. One contains ras in its original uncorrupted form, but beside it Lebedev now has a new lung cell with ras switched on in it forever. And immediately ras takes charge of the cellular machinery and starts the build-up to superfast cell multiplication. A cell running ras full-time won’t cooperate with nearby cells in any other task. It isn’t interested, for example, in being part of a lung. Binary at last, it only wants to become two cells, four cells, eight sixteen thirty-two –

But it’s all right. The body is used to occasional runaway accidents with ras. It has one last defence mechanism. As ras goes crazy, another gene, away over on Chromosome 17, detects the molecular signature of the build-up and neatly, swiftly, initiates cell suicide. The cell dies. With it goes the mutant ras.

This has happened thousands of times.

Another lung cell. Chance upon chance upon chance upon chance. Of all the billions of cells in Lebedev’s lungs, there will be some millions where the diol epoxide gum from his cigarettes stuck itself, not to ras, but to the gene on Chromosome 17 that initiates emergency cell suicide; and of those millions there will be some thousands where the crucial blob blew in just in time to land on a strand of DNA in the midst of cell division, and got itself copied. So, scattered here and there through the billions of cells whose little bulging windows of fat face the channels of the lung, there are some thousands, randomly distributed, where the suicide gene on Chromosome 17, later to be called P53, isn’t working. Here’s one of them. And into it, after fifty years of delicious Kazbek smoke, there flies one more random molecule of goo, and it travels straight to ras to scramble the vital G into C, and it arrives just in time, too, to evade the editorial enzyme and get copied into a new cell.

And it’s not all right. The new cell with mutant ras in charge of it is a tumor unbound, freed from the body’s safety systems to multiply and multiply, unstoppably, selfishly, altogether indifferent to its effect on Lebedev’s lung, and on Lebedev.

This only has to happen once.

NOTES

1 A cell. A lung cell: the molecular biology of this chapter is accurate as far as it goes, and I am assured that the dwindling probabilities of the molecular events in it are at least of the right orders of magnitude. But it should be remembered that the chapter only follows one possible route by which one toxin in tobacco smoke can induce one variety of lung cancer. There are many other routes, other toxins, and other cancers, so a realistic path towards carcinogenesis would be much less linear than the simple illustrative zoom I have selected here. It would trace its way in massive parallel through a massively forking labyrinth of probabilities. I drew heavily on – inhaled heavily from – Theodora R. Devereux, Jack A. Taylor and J. Carl Barrett, ‘Molecular Mechanisms of Lung Cancer: Interaction of Environmental and Genetic Factors’, Chest 1996, 109; 14–19; and on Stephen S. Hecht, ‘Tobacco carcinogens, their biomarkers and tobacco-induced cancer’, Nature Reviews Cancer 3, October 2003, pp. 733–44. I am also indebted to Dr Claerwen James for enlightenment via conversation and email.

How Postmortem Toxicology Testing Uncovers the Truth Behind Unexplained Deaths

In cases where the cause of death is still unknown or suspicious, postmortem toxicology testing is the key to revealing the truth. This scientific method analyzes biological specimens such as blood, urine, hair, and even cremains for the presence of drugs, poisons, alcohol, or other toxins. It's usually the missing piece that brings clarity, closure, and even justice to families and law enforcement.

What Is Postmortem Toxicology Testing?

Postmortem toxicology consists of examining bodily fluids and tissues at death to determine the presence of substances which could have helped bring about or directly resulted in death. Toxicology tests are particularly crucial in:

Sudden, unexplained deaths

Suspected drug overdoses

Potential poisonings

Deaths suspected as being due to foul play

By determining drugs which are not observable during routine autopsy, toxicology tests aid forensic specialists, medical examiners, and loved ones in identifying what actually happened.

Why Legal Professionals and Families Count on Toxicology Tests

Forensic toxicology services are often sought by many families when they believe an autopsy report is too brief or lacking. Toxicology tests provide an added level of examination, particularly in instances that include:

History of substance abuse

Use of prescription or illegal drugs

Suspected homicide via poisoning

Medical malpractice or negligence

Additionally, postmortem toxicology tests can reveal chronic drug abuse or toxic exposure that may not have been apparent in the individual's lifetime.

Frequently Asked Questions About Postmortem Toxicology Q. How long does it take to get a postmortem toxicology test?

A.The majority of standard toxicology panels are finished within 2–3 weeks. Some laboratories, such as The Carlson Company, have express turnaround times available for emergency cases.

Q.Can toxicology reports specify the definite cause of death?

A.Though they may not alone determine the exact cause, they yield important evidence that, together with autopsy results and medical history, can strongly suggest how an individual died.

Q.Can cremated remains (cremains) be tested?

A.Yes. While difficult, sophisticated forensic laboratories can test cremains for the presence of heavy metals, drugs, and poisons.
