How the Nazis faked part of Hamburg to fool Allied bombers
'Operation Invisibility Cloak' was a waste: Hamburg would soon be firebombed to bits
- In 1941, the Nazis camouflaged an entire lake at the centre of Hamburg.
- A painted tarp was made to look like a bunch of city blocks from above, in the hope of misdirecting RAF bombers.
- But the Brits weren't fooled, and Hamburg would later suffer horrific firebombing.
Operation Invisibility Cloak
Before and after: the Binnenalster and Hamburg's central train station.
Now you see it, now you don't: these images, taken by the Royal Air Force in 1941, show how the same part of Hamburg suddenly looked very different from above.
- The most notable difference is the disappearance of the Binnenalster, one of two artificial lakes that mark the center of Hamburg. It has been covered to look like regular city blocks from above.
- Hamburg's Hauptbahnhof, the city's central train station, clearly visible on the top image, has also been camouflaged (although perhaps less effectively).
- A fake bridge, made from wood, wire and thatch, has been slung across the lower part of the Außenalster - the other, larger lake in central Hamburg. By re-creating the actual, hidden Lombardsbrücke, the camouflage operation creates a fake Binnenalster, just north of the real one.
Many attempts at deception

Firstly, because the British bombers targeting Hamburg didn't orient themselves on the Alster lakes. They were guided in by the Elbe, Hamburg's major river.
But most of all, because the Brits caught on quickly to the deception. In fact, the London papers reported on the operation soon after its completion. On July 1941, several published these 'before' and 'after' images.
Operation Tarnkappe was but one of many attempts to deflect the attention of Allied bombers from valuable targets on the ground. Just around Hamburg, the Nazis faked 80 air strips and 32 industrial and traffic installations, while they attempted to cloak real factories, military installations and even Hamburg City Hall.
When the Alster froze in the cold winter of 1940/41, the Nazis planted hundreds of pine trees on the Alster, hoping to trick Allied pilots into thinking they were flying over a forest, instead of the centre of Hamburg.
None of that really made a difference.
Coming within range
As the range of Allied fighter craft expanded, bombing raids deep into Germany became relatively safer for the air crews.
As a major industrial center, home to shipyards and harbor for U-boats, the port city of Hamburg was an important target for Allied bombing raids throughout the war.
As British and American airplane technology advanced, Hamburg came within easier range of the Allied bombing effort.
After concentrating on the industrial Ruhrgebiet in western Germany, closer to the UK, Allied Bomber Command eventually started paying its deadly visits to Hamburg.
In July 1943, the Allies unleashed Operation Gomorrah, history's heaviest aerial bombardment yet. It created a huge firestorm that killed more than 42,000 civilians and completely destroyed 21 km2 (8 sq. mi) of the city.
Payback for Coventry

During the worst night of the attacks, asphalted streets burst into flame, the fiery tornados swept people up into the sky, and many more died of asphyxiation in bomb shelters as the fires consumed all the oxygen in the city above.
A million people fled the city, which saw its production capacity severely handicapped for the rest of the war. After the war, the level of destruction was compared to that of Hiroshima.
Destroying further German cities by firestorm was subsequently called 'hamburgisation' by the Allies; a reply in kind to Joseph Goebbels' cynical invention of the verb 'coventrisieren' to describe the wholesale destruction of a city by aerial bombardment (in reference to the German air raid on Coventry of 14 November 1940).
Central Hamburg today, with the Außenalster and Binnenalster - and even the train station - clearly visible.

Researchers documented the most common negative side effects of smoking weed, and who might be most susceptible.
- A team of researchers identified a total of 26 possible adverse reactions to cannabis use.
- Coughing fits, anxiety, and paranoia are among the top three most common adverse reactions to smoking weed.
- It was the people who smoke on a less frequent basis who were more likely to have had the bad experiences.
The most common adverse effects of pot<p>As it turns out, coughing fits are among the top three most common adverse reactions to cannabis use, along with anxiety and paranoia, according to a new study published in the <em>Journal</em><a href="https://jcannabisresearch.biomedcentral.com/articles/10.1186/s42238-019-0013-x" target="_blank"><em> of Cannabis Research</em></a>. </p><p>Now that weed is legal in the state, a team of researchers at Washington State University sought to document potential negative reactions to cannabis in order to paint a detailed picture of the effects of smoking weed for newbies. The authors surveyed more than 1,500 college students on the specific type and frequency of adverse reactions they had experienced while using pot. Additionally, the students in the study were surveyed about their demographics, personality traits, reasons for using cannabis and their use patterns. </p><p>Despite marijuana's <a href="https://bigthink.com/sex-relationships/marijuana-sex" target="_self">numerous benefits</a>, the team identified a total of <a href="https://jcannabisresearch.biomedcentral.com/articles/10.1186/s42238-019-0013-x/tables/2" target="_blank">26 possible adverse reactions to</a> the drug. More than half of the study participants reported having coughing fits along with anxiety and/or paranoia while using cannabis. The most frequently occuring of these were the coughing fits, along with chest/lung discomfort and body humming. A subset of the study group reported these reactions occurring around 30–40% of the time they were using pot. On the flip side, the three <em>least</em>-commonly reported reactions to cannabis use were fainting, visual hallucinations and cold sweats. </p><p>"There's been surprisingly little research on the prevalence or frequency of various adverse reactions to cannabis and almost no research trying to predict who is more likely to experience these types of adverse reactions," <a href="https://news.wsu.edu/2020/03/30/new-research-sheds-light-potentially-negative-effects-cannabis/" target="_blank">said Carrie Cuttler</a>, assistant professor of psychology and an author on the paper, according to WSU News. "With the legalization of cannabis in Washington and 10 other states, we thought it would be important to document some of this information so that more novice users would have a better sense of what types of adverse reactions they may experience if they use cannabis."</p><p>The most distressing of the 26 negative reactions were panic attacks, fainting, and vomiting. Yet, the survey data suggested that cannabis users generally do not find even acute adverse reactions to cannabis to be severely distressing.</p>

Tea and coffee have known health benefits, but now we know they can work together.

- A new study finds drinking large amounts of coffee and tea lowers the risk of death in some adults by nearly two thirds.
- This is the first study to suggest the known benefits of these drinks are additive.
- The findings are great, but only directly apply to certain people.
Maybe you should enjoy this article with a cup of coffee or tea.<p> The <a href="https://drc.bmj.com/content/8/1/e001252?T=AU" target="_blank" rel="noopener noreferrer">study</a> involved 4,923 type 2 diabetics living in Japan. The average participant was 66 years old. All of the participants were taken from the rolls of the Fukuoka Diabetes Registry, a study geared at learning about the effects of new treatments and lifestyle changes on the health of diabetics. <br> <br> The participants filled out questionnaires concerning their health, diet, habits, and other factors. Among the questions were two focused on determining how much green tea or coffee, if any, the participants consumed over the course of a week. The health of the participants was recorded for five years. During this time, 309 of the test subjects died from a variety of causes. <br> <br> Subjects who drank more than one cup of tea or coffee per day demonstrated lower odds of dying than those who had none. Those who consumed the most tea and coffee, more than four and two cups a day, respectively, enjoyed the most significant reductions in their risk of death. This level of consumption was associated with a 40 percent lower risk of <a href="https://www.sciencedaily.com/releases/2020/10/201020190129.htm" target="_blank" rel="noopener noreferrer">death</a>. </p><p>Most interestingly, the effects of drinking tea and coffee appear to combine to reduce risk even further. Those who reported drinking two or three cups of tea a day and two or more cups of coffee were 51 percent less likely to die during the study, while those who drank a whopping four or more cups of tea and two or more cups of coffee had a 63 percent lower risk of <a href="https://www.medicalnewstoday.com/articles/diabetes-coffee-and-green-tea-might-reduce-death-risk" target="_blank" rel="noopener noreferrer">death</a>. </p>
So, should I start swimming in a vat of coffee and green tea?<iframe width="730" height="430" src="https://www.youtube.com/embed/LY0E-JQxeoY" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe><p> Not quite. </p><p> The primary takeaway from this study is that Japanese adults with type 2 diabetes who drink a lot of green tea and/or coffee die less often than similar people who do not. If this effect is caused by something in the drink, lifestyle choices people who drink that much tea all make, or something else remains unknown. The finding must be considered an association at this point. <br> <br> The eye-popping reductions in mortality rates are compared to the risk of death of others in the study. The people who died reported drinking less tea and coffee than those who lived. Unless you have several demographic and conditional similarities to the subjects of this study, you probably won't suddenly be at a two-thirds lower risk of death than your peers because you drink green tea. </p><p> Like all studies that depend on self-reporting, it is also possible that people misstated how much they consumed any one item. The study also did not look into other factors like socioeconomic status or education level, also known to impact death rates and potentially linked to coffee and tea consumption. </p><p> However, it is yet another study in the pile that suggests that <a href="https://www.healthline.com/nutrition/top-13-evidence-based-health-benefits-of-coffee" target="_blank" rel="noopener noreferrer">coffee</a> and <a href="https://www.healthline.com/nutrition/top-10-evidence-based-health-benefits-of-green-tea" target="_blank" rel="noopener noreferrer">green tea</a> are good for you.

This study also suggests the benefits are additive, which is a new development.</p><p><br> So, while it isn't time to start the IV drip of green tea, a cup or two probably won't <a href="https://www.webmd.com/diabetes/news/20201022/coffee-green-tea-might-extend-life-for-folks-with-type-2-diabetes" target="_blank" rel="noopener noreferrer">hurt</a>. </p>
But most city dwellers weren't seeing the science — they were seeing something out of Blade Runner.
On Sept. 9, many West Coast residents looked out their windows and witnessed a post-apocalyptic landscape: silhouetted cars, buildings and people bathed in an overpowering orange light that looked like a jacked-up sunset.
