Charles Joughin: how whiskey saved the head baker of the Titanic


Joughin would be at the topmost part of the ship by this point.
Loss of the Titanic.
Published in the Graphic Supplement of 27 April 1914

From History Defined by Robert Carlock

Charles Joughin was an acclaimed chef.
He was best known for being the head baker on the RMS Titanic.

Although the extravagance of the voyage is well known, the pastries that Joughin was responsible for creating are not why he is remembered. Instead, Joughin is best known for his remarkable survival in the face of imminent death.

Historians and scientists attribute his survival to one thing: the sheer amount of alcohol he consumed that night.

The Unsinkable Ship

On April 10, 1912, the maiden voyage of the RMS Titanic would begin.
At the time, the Titanic was one of the largest passenger ships in the world.
It was one of three Olympic-class ships designed by the White Star Line. 

The ship had ten decks, could carry almost 2500 passengers, and was manned by nearly 1000 crew members.
The maiden voyage would only last five days before the Titanic struck an iceberg in the frigid North Atlantic. It sank within two hours.

Although other ships would eventually arrive to pull survivors from the water, only 706 people survived.
Over 1500 would be lost to the icy waters.
This made the sinking of the Titanic the worst maritime disaster to occur during peacetime.

The Titanic Strikes an Iceberg

After the ship began taking on water, panic began setting in.
Some people did not believe they were in trouble since the ship had been marketed as “unsinkable.”

Some stubbornly refused to leave their belongings or quarters that they had paid for.
While others were unaware anything was even wrong.

As it became clear the ship was going down though, many of the crew began insisting that people evacuate the ship and climb into lifeboats.
The Titanic had half as many lifeboats as it was supposed to. Nearly all of them were less than half-filled when they cast off.

Charles Joughin would rally his fellow chefs and bakers to assist in the process of evacuation.
In between rounds of assistance, Joughin would step below deck to have a drink of whiskey, which likely helped keep him warm.

As the ship continued to sink, Joughin maintained this pattern: assist others into lifeboats, go below deck to take another drink, then return to the deck to continue assisting others.
Joughin assisted other crew members in ensuring women and children made it into lifeboats, sometimes even against their will.

They would toss people into any boat that had space before it was cast off from the ship.
Joughin also worked with his staff to throw chairs and other makeshift floatation devices overboard. These were intended to help any other survivors after the ship completely sank.

Joughin Overboard

This continued for hours, until around 2:20 am.
At this time, the sinking ship finally dipped below the waves of the icy northern Atlantic.

Joughin went down with the ship.
He climbed the stern of the boat and stood at the tip.
He rode it down into the water like an elevator.
Joughin and other witnesses even claim that he was able to calmly step into the water as the ship went down, without even getting his hair wet. 

Surrounded by the screams and cries of other survivors, and those frantically trying to stay alive in the frigid waters, Joughin remained unnervingly calm.
He gently trod water for over two hours that night.
He kept afloat until the sun began to rise.

As the early morning light began to fall over the wreckage, Joughin found an overturned lifeboat with other survivors.
While they could not fit him on the boat, they recognized him and held him partially out of the water until they found another lifeboat with space.

Finally, the RMS Carpathia arrived at the scene and began rescuing survivors.
Joughin was pulled from the water.
He only suffered from swollen feet. 

How did Charles Joughin Survive?

Scientists have sought to explain how he survived.
They have determined that his alcohol consumption was likely the key factor in Joughin’s survival, against common sense.

On one hand, alcohol dilutes blood vessels.
Generally, this makes people more susceptible to hypothermia through a process called vasodilation.
This process expedites heat leaving the body through increased blood flow to the skin.

On the other hand, most people who are submerged in cold water die of “cold shock” rather than hypothermia.
The experience of being submerged in water below even 50 degrees Fahrenheit can lead to rapid, shallow breathing, tightened blood vessels, and other panicked responses from the body.

Most people die from drowning or cardiac arrest before hypothermia can set in.
In Joughin’s case, these two canceled each other out.

His diluted blood vessels from the alcohol constricted to normal size with the freezing water.
The psychological effects of the alcohol kept Joughin from feeling the intense cold and having a neurological response of panic.

Since he could not sense the danger, his body did not react.
In this rare case, alcohol saved his life.

Consuming vast amounts of alcohol is not healthy or a suggested practice for nearly any circumstance. It causes increased heart rate, dilated blood vessels, impaired thinking, and slurred speech.

But this perfect storm of symptoms is what saved Joughin. It canceled out the physiological response of cold shock.
This allowed him to gently tread water for over two hours in the frozen Atlantic Ocean.

His survival, along with the image of a drunken baker stepping off the end of the ship like an elevator, has cemented Joughin’s legacy in the history of the Titanic.

Plastic in the ocean and on our plates: What are the risks to human health?

Plastic that enters the marine food chain can end up on our plates.

From The Conversation by Amélie Châtel

It’s no secret: when we savour a delicious piece of fish or a platter of seafood, we’re not just consuming valuable omega-3s and vitamin D. Alongside these benefits come less appetising elements — countless micro- and nano-plastics.

These plastic particles, measuring less than 5 millimetres, enter our oceans through human waste and penetrate the food chain
According to an Ifremer study, around 24,400 billion microplastics are floating on the ocean’s surface. These particles are found in all marine organisms — from microalgae to fish, which occupy higher levels of the food chain. 
This phenomenon not only threatens marine ecosystems but also raises concerns about potential risks to human health.

What exactly do we know about the accumulation of these pollutants in marine life and the dangers they pose to human health?
 
 
Marine organisms bioaccumulate micro- and nano-plastics that humans discharge into the sea.  
 
Micro- and nano-plastics: an invisible threat

Since the 1950s, plastic production has grown exponentially, reaching 58 million tonnes in Europe in 2022 alone. 
This has led to massive amounts of waste.

Over time, wind, waves, sunlight and microorganisms break down larger plastic waste into microplastics (1–5 mm) and nanoplastics (smaller than 100 nanometers), which now contaminate all parts of the environment, including the air, soil and water.

The process by which these plastics accumulate in organisms across different levels of the food chain is known as “bioaccumulation”.

Research from our laboratory reveals that in aquatic environments, micro- and nano-plastics are ingested by a wide range of species — from microalgae at the base of the food chain to top predators like eels.

The impact on marine life

These ingestions have serious consequences. Studies show that microplastics can cause toxic effects in marine animals.

For instance, in mussels, microplastics can block digestive systems, activate immune responses, cause DNA damage and interfere with the expression of genes essential to various cellular functions.

The severity of these effects depends on the plastics’ size, composition, degree of degradation and any harmful chemical additives they may contain.

Plastics often contain high levels of phthalates, which are endocrine disruptors.
These chemicals can interfere with hormonal systems, posing risks not just to marine life but potentially to humans as well.

Risks to human health

Plastics ingested by marine animals inevitably make their way into our food supply.

Frequent seafood consumers are estimated to ingest thousands of microplastic particles annually. Although research on the precise health effects on humans is ongoing, some troubling hypotheses have emerged.

Once inside the human body, these particles may cause damage similar to that observed in fish.

Studies on human cells indicate that micro- and nano-plastics can disrupt cellular functions in ways akin to the effects seen in marine organisms.
Scientists are particularly concerned about the toxic impacts of plastic additives.

Additionally, micro- and nano-plastics can act as carriers for pathogens or bacteria, potentially increasing the risk of infectious diseases.

The urgency to tackle plastic bioaccumulation in the food chain cannot be overstated.
By taking swift action to limit plastic usage and improve recycling technologies, we can slow the progression of this environmental and health crisis.

Airlines, shipping companies and sleigh drivers rush to update crucial navigation systems ahead of Christmas rush

Magnetic declination (the angle between magnetic and geographic north) in 2025 according to WMM2025.
Red is magnetic north to east of geographic north; blue is to west.

From BGS 
 
Release of major upgrade to a new model tracking magnetic north prompts global reset of satellite tracking systems across trade and passenger transport routes.
 
Hundreds of thousands of mariners, airline operators and North Pole-based gift distribution specialists will be rushing to update their navigation systems after the launch of a new model tracking magnetic north, which is crucial to the accuracy of global positioning systems (GPS) that are relied upon across the world.

In partnership with the UK Defence Geographic Centre and the US National Geospatial-Intelligence Agency (NGA), BGS and the US National Oceanic and Atmospheric Administration (NOAA) have teamed up to update the World Magnetic Model (WMM).
 
 
 
The WMM is the standard model used by the United Kingdom and the United States governments, including the U.S. Federal Aviation Administration and the U.S. Department of Defense, as well as organizations with an international remit such as the North Atlantic Treaty Organization (NATO), the International Hydrographic Organization and the UK Hydrographic Office.

The model comprises a series of magnetic field maps that track changes in the magnetic field, such as the spot at which compass needles point in the northern hemisphere.
To ensure pinpoint accuracy, it is crucial that the shifts in magnetic north, which are caused by flow of the liquid iron in the outer core of the Earth, are taken into account in the electronic equipment that is trusted to guide global trade and enable the safe transit of travellers across the planet.
 
From GPS-enabled mobile phones to nuclear submarines, this improved resolution update will allow navigation with more accuracy than ever before to take place in the run up to Christmas — vital for all those who do not have a red nose to follow.
The WMM is officially released today, ensuring users can have the most up-to-date information so they can continue to navigate accurately for the next five years.
The current behaviour of magnetic north is something that we have never observed before. Magnetic north has been moving slowly around Canada since the 1500s but, in the past 20 years, it accelerated towards Siberia, increasing in speed every year until about five years ago, when it suddenly decelerated from 50 to 35 km per year, which is the biggest deceleration in speed we’ve ever seen.
Dr William Brown, global geomagnetic field modeller at BGS.
While each model predicts how magnetic north will shift over the five-year period to limit any error, the change will have an impact on travellers.

Imagine someone was planning to travel by sleigh from a chimney top in South Africa to a snow covered-roof in the UK, a journey of around 8500 km. Using the previous WMM and setting off just one degree off-course, he would end up approximately 150 km away from where he should[1].
With a margin of error of only a few inches between chimney flues, this could cause significant issues.
Values from the updated model can now be calculated, and the WMMHR2025 and the WMM2025 are available for download.
