Heavy Traffic And A Possible Link With Dementia

The Guardian has an article here about a possible link between heavy traffic and dementia:

People living near a busy road have an increased risk of dementia, according to research that adds to concerns about the impact of air pollution on human health.

Roughly one in 10 cases of Alzheimer’s in urban areas could be associated with living amid heavy traffic, the study estimated – although the research stopped short of showing that exposure to exhaust fumes causes neurodegeneration.

Hong Chen, the scientist who led the work at Public Health Ontario, said: “Increasing population growth and urbanisation has placed many people close to heavy traffic, and with widespread exposure to traffic and growing rates of dementia, even a modest effect from near-road exposure could pose a large public health burden.”

Previously, scientists have linked air pollution and traffic noise to reduced density of white matter (the brain’s connective tissue) and lower cognition. A recent study suggested that magnetic nano-particles from air pollution can make their way into brain tissue.

The latest study, published in The Lancet, found that those who live closest to major traffic arteries were up to 12% more likely to be diagnosed with dementia – a small but significant increase in risk.

The study, which tracked roughly 6.6 million people for more than a decade, could not determine whether pollution is directly harmful to the brain. The increased dementia risk could also be a knock-on effect of respiratory and cardiac problems caused by traffic fumes or due to other unhealthy life-style factors associated with living in built-up urban environments…..

All this research shows is that, after allowing other factors such as wealth and other health issues, there seems to be a small increased risk of dementia. However it’s not clear whether it’s caused by air pollution, or by noise that disturbs people’s sleep patterns. Or it could even be that people who are more susceptible to dementia simply have a preference for living in busier, more bustling environments , or that people at less risk of dementia have an underlying wish to live in quieter places….

One Of These New Elements Should Be Named “Rayleighium”!

You may seen in the media that the existence of four new chemical elements has been verified. They are all highly unstable, they only exist for fractions of a second before decaying into other elements. In fact they are so unstable that scientists can only create one atom of them at a time. But they are all genuine elements , as genuine and distinct as more common ones like iron, or copper, or tungsten.

At the moment they have temporary names – ununtrium, ununpentium , ununseptium ,and ununoctium. They will eventually be given permanent names, most likely after a place, a country or a scientist. In the past , for example “Einsteinium” was named after Albert Einstein.

Now, there is a serious case for naming one of these new elements “Rayleighium”. Not after Rayleigh, but after Lord Rayleigh the physicist. You may not have heard of him, but he was a world-class scientist, the Stephen Hawking of his day.

Back in the 1800s a certain Lady Charlotte Strutt married into an Essex family,was raised to the peerage and although she didn’t live in the town chose the pleasant-sounding title of Baroness Rayleigh.Her grandson William eventually became Lord Rayleigh and a very important physicist : –

  • He explained one of the oldest questions that anyone asks – why is the sky blue? The answer is Rayleigh scattering.
  • Together with William Ramsay , he discovered an element himself – Argon. Having both their names beginning with “Ra” is a coincidence…
  • He proposed the main theory – the duplex theory – as to how humans can locate where a sound is coming from.
  • He predicted the existence of Rayleigh Waves – waves that travel through solids close to the surface. These crop in all sorts of situations. Rayleigh Waves are caused by earthquakes , are used in non-destructive testing of materials , and may even be used by elephants for communicating.
  • He won the Nobel Prize for Physics in 1904, and has a crater on the moon, a crater on Mars and an asteroid named after him.

It would certainly put Rayleigh on the map if one of these elements was named Rayleighium! The man deserves it. Or Raylium, if that was easier to spell and honoured Ramsay as well.

A rainbow over Rayleigh - Isaac Newton explained the rainbow but it was Lord Rayleigh who explained why the sky itself is blue.

The First Flyers Of Fambridge

Early hot air balloon flight, 1784

The bookstall inside Rayleigh Lanes recently had a couple of copies of “Essex And Its Race For The Skies 1900-1939” by Graham Smith.

As you’d expect from the title, it deals with flying in Essex before WW2. But it also covers flights in Essex before 1900. A really long time before.

Let’s go back to 1783. The Montgolfier Brothers in France invent a hot-air balloon and Etienne Montgolfier makes the first manned ascent. News of this travels fast.

By the next spring there are already flights taken in place in England. On June 3rd 1784 one arrived at Fambridge! According to the diary of John Crosier, A Maldon miller:

“3rd June, a large balloon descended in a field near Fambridge … with Major Money and another gentlemen, both heavy men. They came down about three o’clock in the afternoon, pack’d it up and convy’d it to Maldon in a cart. The car, in the form of a boat, was superb’

It’s not altogether clear that this was South Fambridge rather than North Fambridge. But even so , it must have been a startling site for anyone who saw it. Men descending out of the sky!

Some Good Places To Visit During The Olympics 2

Rayleigh Mill

If you are coming to Hadleigh for the Olympics, you might fancy coming to Rayleigh for a meal. There are plenty of cafes and tea-rooms, and a good range of restaurants – whether you want Fish and Chips, Italian, Spanish, Chinese or Indian. Plus lots of pubs….


And if you want to go a bit further, and eat by the river, you can have a very good meal at Hullbridge or Battlesbridge.

If you’ve come from abroad, and are interested in science, then you could drive to Paglesham, where the remains of Darwin’s Beagle are somewhere in the river bed. There’s absolutely nothing of H.M.S. Beagle to actually see, but the pubs do good food and it’s a very tranquil place to walk.

And if you are more religious-minded, there are plenty of ancient village churches to see, including one at Paglesham. The view from the churchyard at Ashingdon is particularly fine.

Join In The Big Butterfly Count !

The Guardian explains things pretty well here:

If this summer’s 50 shades of grey are getting you down, imagine how miserable it is to be a winged insect. In what is shaping up to be the worst year on record for butterflies, Sir David Attenborough on Wednesday urged people to find a window of sunshine and join the biggest butterfly count in the world.
The wettest April for a century and the dampest June on record has left lepidopterists despairing about the fate of Britain’s 59 species, almost three quarters of which are in decline and one third are in danger of extinction.
Launching the third year of Butterfly Conservation’s Big Butterfly Count, the biggest citizen science project of its kind in the world, Attenborough said it was more important than ever to discover if butterflies are dodging the downpour. The count, in which people are asked to record online all the common species they spot in a 15-minute window in their garden or local park, will alert conservationists to the species most in danger so efforts can be better targeted to prevent their extinction.

You can find out more on the Big Butterfly Count website.

You simply download and print their identification chart and spend 15 minutes when its sunny noting what butterflies you see.

You could do this in a garden, or park or field, or one of our woods. You can then submit your findings, and they go onto an interactive map:

A couple of thoughts :

  • Our district doesn’t have any results yet on the map
  • This is a reminder of how important wildflower meadows are in places like Sweyne Park.
  • “Its the people who make a town special, though”

    Chris Black has an article on the Guardian website today, on this special morning for Rayleigh. Here is the text, with some added links and photos:

    ” If you want to see the most charming council house in Britain, come and visit the Dutch Cottage in Rayleigh. Its tiny, octagonal and thatched and although it has tenants living there, the public can visit on Wednesday afternoons. An Olympic torchbearer will be running past it today.

    I cant help thinking that if this little cottage was in a more fashionable town Tunbridge Wells or Lewes, or somewhere like that it would be more famous. But Rayleigh, situated between Chelmsford and Southend, seldom gets into the headlines.
    Our most spectacular death was the Rayleigh Bathchair Murder of 1943, when a downtrodden teenage son killed his father by concealing an anti-tank mine under his cushion. (I was told that the jury thought the father such a tyrant that they would have let the son off, had he not also put his fathers nurse in danger). Our most celebrated birth was in 1969, when the Hanson quintuplets were born to a Rayleigh family the first surviving quins in the UK.

    Oddly enough, a quirk of aristocratic history makes Rayleigh a familiar name to physicists. Back in the 1800s, a certain Lady Charlotte Strutt married into an Essex family, was raised to the peerage and though she didnt live here chose our towns name to acquire the pleasant-sounding title of Baroness Rayleigh. Her grandson, Lord Rayleigh, went on to become one of Britains greatest physicists, and thus Rayleigh must lend its name to more scientific terms than any other town or city in the world a minor planet, a lunar crater and a Martian crater all bear our towns name. Beat that, Tunbridge Wells.

    Of all these terms, Rayleigh Scattering is my favourite: the scientific explanation of why the sky is blue which I think makes our skies extra-interesting, even if theres not been much evidence of the effect in recent weeks. And yet another scientific link to Rayleigh is the suggestion that the remains of Darwins legendary ship, HMS Beagle, lie on the river-bed just a few miles away in Paglesham.

    Its the people who make a town special, though. I remember chatting with one chap at a barbeque, who told me he was in training for his second marathon. How did he happen to do his first? Well, one of his mates in his amateur football team had just lost his wife to breast cancer, and had decided to raise funds by running in the New York marathon. So the widowers team-mates entered the same race, trained for it, booked themselves on the same flight and into the same hotel all without telling him. When the team turned up at Heathrow, he was touched, thinking they had come to see him off. Then he saw they all had luggage, and burst into tears.

    Its people like that who make me proud of this town, and Im sure well give the torchbearer a rousing welcome today. This is a place of quiet pleasures and excellent, bacon-topped pork pies. If Derbyshire has the Peak District, then perhaps the Olympic torch has now reached the picnic district.”

    A Guest Post On Snakes And Science

    We have a guest post for the third day running…. this is from District Councillor John Mason – about a personal scientific project he has been working on in Cyprus….

    Protecting Snakes And Humans

    Chris Black, the Editor of OnlineFOCUS spotted a personal video clip of mine on the internet which was about my friend Snake George who was testing a snake deterrent that I had designed.

    He invited me to write an article about this diversity in my interests.

    My family’s interest in Cyprus is that we spend many of our holidays there and having been an amateur herpetologist since I was 7 it was no surprise that I went to meet Snake George, real name Hans Jorg Wiedl, at his Reptile Park about 12 years ago now. George is an expert in the Snakes, Lizards and Amphibians of Cyprus. He has written many articles and at least two books.

    Snake George (Hans-Jorg Wiedl) re-discovered the Cyprus Grass Snake after it had been thought extinct for nearly 40 years. Secondly he proved that the most venomous snake on Cyprus, the Blunt Nose Viper lays eggs, other than bearing live young as it had been thought and apparently proven.

    George has been working hard to win the right from the Cyprus Government to establish a conservation and breeding project to save the Cyprus Grass Snake from extinction. I have run a Petition at the EU Parliament to bring this into focus for action before it is too late. There are some articles that I have written about this on http://rochfordessex.com/cyprusreptiles

    Many people in Cyprus are frightened of snakes and, despite education, this will probably remain so for several generations.

    The worst part is that all snakes suffer from indiscriminate killing, even the harmless ones!!

    This is placing all species at risk and especially now in Cyprus the Large Whip Snake (harmless) which is a natural predator, ironically, of the Blunt Nosed Viper which is the only venomous snake in Cyprus that can endanger human life.

    George and I were having coffee at the New Roots Garden Centre near Coral Bay one morning and he lamented that the product that he had been selling on as Snake Buster was ShooSnake (I think) from Australia and he had been banned for importing this by the Cyprus Authorities. He reckoned that a repellent would still help conserve snakes as they would not frequent areas where people do not want them. I agreed to research the substances used in current products under safety for use in the environment and that which could be imported into Cyprus with a chemical license and distribute for use as a pesticide.

    The EU fairly recently banned practically every pesticide previously in use and licensed in the EU, which includes Cyprus.

    The product that I have produced has been tested initially by George. There is scientific data which backs up the recommendation I made on the basis of my research.

    There are a number of commercial snake repellents on sale in Cyprus. Some are electronic. It is not clear whether Cyprus has any natural safe snake repellents available to help people ward off snakes from their homes, business premises and gardens. If the snakes are repelled from the place then everyone is happy, especially the human.

    It is a CONSERVATION PROJECTit conserves and protects both snakes and humans!!

    There are harmful materials that people might use but these are also harmful to the human species!! And environmentally dangerous.

    With the knowledge I had gained at QMC, London and the ecology of Cyprus snakes I had learnt since then my independent research has been undertaken on ancient ethnobotanical archives in order to derive such a product with the safest possible attributes.
    It does not involve chemicals only plant extracts which are safe for both humans and the environment but repel snakes. My research has produced a product that achieves these objectives. This is a very important project for Cyprus given the issues that humans have with snakes. I would welcome any input offered on the commercial aspects of this project.
