graphene...restoring eyesight.

Graphene’s potential is being talked about again, and this time it could help restore the eyesight of millions of people.
The World Health Organization estimates that about 253m people across the world live with some form of vision impairment, many of which are caused by chronic eye diseases.
However, unlike many other medical conditions, these effects can be prevented or completely reversed in 80pc of cases.
This is largely to do with a lack of access to readily available medical services in some of the poorest countries, but a new artificial retina could one day drastically change this.
A world first
Presenting its findings to the American Chemical Society, an international team of researchers said it has successfully developed and tested the world’s first ultra-thin retina from the ‘wonder material’ known as graphene.
The flexible device could be implanted within a person’s eye and, with a few modifications, could be used to track heart and brain activity when placed in other parts of the body.
The device is based on how the natural retina works, whereby it contains specialised photoreceptor cells known as cones and rods.
Converting incoming light into nerve signals, these impulses travel into the brain via the optic nerve and are then decoded into visual images.
In diseases such as macular degeneration and diabetic retinopathy, retinal tissue is destroyed as they take hold, leading to vision loss or complete blindness.
With no known cure, researchers have worked to develop retinal implants to bypass the damaged tissue, but existing silicon-based devices are rigid, flat and fragile. On top of that, they often produce blurry or distorted images to the detriment of the user.
‘A very exciting starting point’
This latest device, meanwhile, used graphene and molybdenum disulphide as well as thin layers of gold, alumina and silicon nitrate to create a flexible, high-density and curved sensor array.
Resembling a flattened football, the device can conform itself to the shape of a natural retina without mechanically disturbing it.
“Although this research is still in its infancy, it is a very exciting starting point for the use of these materials to restore vision,” said Nanshu Lu of the research team.
Looking to the future, the team is aiming to integrate the technology into mechanically and optically imperceptible electronic tattoos that are laminated on the skin surface to gather real-time health information.

Get that stock market .............????

Didn't realise there were music lovers here. To avoid clogging up the VRS site there's a site ROCK where people post interesting music. I'm into most styles except rap which is more about the words than music. Floyd,Led Zep, AC/DC and blues. Try this clip especially if you're a biker (I have a couple). -



Apologies to VRS readers , back on topic in the morning.

As it's late I'll join in. Nothing wrong with Meridian as I said tonal qualities are a personal choice. Meridian make other components apart from speakers and their total sales are less than Linn at £10m.
LUFC I have a Sondec with a Naim power supply Ittok arm and Koetsu cartridge. I recently spent an evening with a dealer who demonstrated streaming/CD and vinyl in a system probably costing nearly £100k. Streaming was a Naim costing £5k+, the CD was £15k+ and the deck £1.5k max. The streaming sound came last by a long way, the CD was OK and the deck easily out performed the others. I was given an explanation but it's too much for a VRS site.
I agree wireless speakers for the masses due to the convenience. I've heard the mu-so and it's fine for youtube whilst on the computer but way down the list for serious listening. It depends on how you want to listen to recorded music. For serious listening and in my case enjoyment vinyl tops the others but CD can be quite good.

IMHO everyone hears slightly differently.....

[haz101] 20/8/2018 23:42

Serratia - chicane, good taste :)

[lufc5] 20/8/2018 23:38

Wireless speakers, for the future masses.....

I have Naim for source/amps but Mission for speakers. American but quality and quantity perhaps?

[1crackupboom] 20/8/2018 23:29

Best home speakers in the world are British and made by Meridian based in Huntingdon. They are sold all over the world and cost between 10k and 60k depending on size. They are the inventors of MQA music. Already tried to introduce Neill to Meridian via Twitter. Meridians speakers are so good only something like Graphene will improve them further. I have 30k of Meridian equipment so can gaurantee there is nothing even close at that price point.

[lufc5] 20/8/2018 23:24

I have linn. Just saying.

[lufc5] 20/8/2018 23:22

Yes, but I'm only talking 4 months. Been here quite a while, and will be in a while after. Could well be massive.

[serratia] 20/8/2018 23:20

Bootie 64 as promised. As it's a little off topic apart from the conclusion I'm posting it outside normal hours -

HIFI speakers my thoughts -

I'm making the assumption that VRS would target an upmarket brand and preferably British. The company would be innovative and sell a descent volume each year. Very high end speakers can cost up to £1m a pair but probably sell very few and the names would be unknown to most people. So, who makes speakers in reasonable volumes and are British?

Three companies stand out as being fairly well known and up market. Naim, Linn and B&W.

Naim - They make all components of a hifi system but stopped making speakers in 2016 to concentrate on their electronics. They said they may resume speaker manufacture at some stage. Annual sales across all components £26m. Good name and image but out for now and fairly small. They were taken over in recent years by a French company.

Linn - Best known for their legendry deck but again make all the hifi components. Speakers cost from £5k to £50k. Sales £16m. Good name/image but small turnover in speakers. British based in Scotland.


B&W - Were British for many years but now American owned. They still have a place in Worthing but I think they manufacture in China now. Considered British by most people. These guys only make speakers. Sales around £150m / year. Speaker prices £3 - £30k.



CONCLUSION - B&W is the best choice of upmarket speakers with a good level of sales and a British image.


Disclosure - Speakers all have different tonal qualities and appeal to different people depending on which characteristics float your boat. Speakers also have to be matched to the amplifier and source components. My speakers are at the lower end of up market hifi (£7k). I do aspire to the next model in the range which is £16k. I have a large VRS holding from very early days so could easily sell a small number to upgrade but as Neill says the story is only just beginning. I haven't sold any shares and will continue to sit and listen to my present pair for many years yet. Playing now - The Best of Chicane.

[sonsonnyjim] 20/8/2018 22:59

LUFC - many on here have predicted more than that. Depends on news :)

[lufc5] 20/8/2018 22:51

Friends of people within the gov' will obviously now know of this company. They should have money and many contacts. Expect this to be increasing in sp,over £2 by this xmas?

[sonsonnyjim] 20/8/2018 22:45

For guys that watch the funds - how much longer can this sustained selling continue?

[festario] 20/8/2018 22:23

Thanks Lovat, and exactly SuperG!When there is a huge amount of net sells, yet the price goes up, that's got to be a good sign.

[superg1] 20/8/2018 22:15

Two ways of looking at it. If the finds hadn't dropped in supply then PIs would have had to pay a lot more for them.

Also of funds keep holding on then they would at some point sell into other major news.

Take Lombard. Absolutely fantastic that they handed over 27 million shares over £1 ago to PIs.

Blackrock, Unicorn and others handed millions over at 10p.

Miton shifted 7 mill or more at half this price due to redemptions. Just months back they had something like 15 million shares, 11mill were gone by the end of June.

It's supposed to go down when funds sell.

[lovat scout] 20/8/2018 22:08

Fest - been off grid. MMs get really uncomfortable when they are holding shares at a high so will always be looking to sell them on to avoid holding the baby.

When MM sellers are competing, and it doesn’t have to involve huge numbers of shares, they keep undercutting each other which is why sometimes the prints give the impression of multiple holders selling off.

Trying to find out what exactly is happening by looking at the prints is at best a guesstimate. A seller of 250k may have their order filled in 10-20 smaller clips so we’ll all be none the wiser.

Good volume is always a healthy sign in my book.

[nemo19] 20/8/2018 21:54

Hear hear Grab

[grabster] 20/8/2018 21:18

I too don't give a toss about who is selling - I am happy with what the share price is doing and what the company is doing.

[festario] 20/8/2018 20:57

I'm on a high, that's for sure.

[bootie64] 20/8/2018 20:49

My word, from posting this afternoon and reading other posts everybody seemed on a high, in good spirits and excited for the future potential of this fantastic company that Mr Ricketts and his team have delivered in spades so far, working all sorts of hours and weekends.

What a difference in a few hours, is it a full moon tonight?
