You Can Contribute.

Here’s just a little reminder for everyone, and some information for new members here: If you delve into the history of this blog you’ll find a number of ways you can contribute.


The bookmarks competition finishes on New Year’s Day. Design me some bookmarks that use the Jon Sullivan artwork and display the eddress of this blog and you could be the winner of some signed copies. The winner gets the Cormac series and the Spatterjay series (new covers), second place gets the Spatterjay series, whilst the top three additionally get copies of my books that they haven't got in their collection ... oh, and when I say that, I mean any of the Macmillan books - all signed of course.

I’ve been running a series of profiles and still want contributions. The title was ‘Who Reads My Books?’ For anyone who is interested, I’d like a short biography and some photographs of you. Tell me about yourself, advertise if you want, if you have a blog or a website of your own then let me know. Thus far (if my recollection is right) we have plenty of IT guys, a pilot, a geneticist, writers, a composer, jewellery maker and much more besides. But don’t be intimidated by these – I want to know about YOU and your interests. Remember, before I got where I am now I used to cut grass for a living.

It’s also interesting to see photos of people’s SFF collections. I enjoy having a look at them and so do many of those who come here. Let’s have a look!

Send your photographs etc here ndotasheratvirgindotnet

Finally, I’ll shortly be doing another video clip to post up here so I would like some more questions. I’ll answer as many of these as I can within the 10 minutes allowed (You Tube) then carry over what’s left to the next clip. Post your questions in the comments section here.

More Marie Srbic Bookmarks

More bookmarks for the competition, which is open for another two weeks...



Piltdown Man

Just for those of you that might not have heard of this, here's how scientific fraud can put us back years. it also seems to be an episode from which little has been learned.

Whoever perpetrated the crime, it is considered to be one of the most damaging scientific hoaxes of all time, because it set the development of evolutionary theory back for years while researchers labored pointlessly to integrate a fake skull into the fossil record.


From The Skeptic's Dictionary, which rather amused me considering the stance there on other matters (I put the bold bit there):

Because of the public nature of science and the universal application of its methods, and because of the fact that the majority of scientists are not crusaders for their own untested or untestable prejudices, as many pseudoscientists are, whatever errors are made by scientists are likely to be discovered by other scientists. The discovery will be enough to get science back on track. The same can't be said for the history of quacks and pseudoscientists where errors do not get detected because their claims are not tested properly. And when critics identify errors, they are ignored by true believers.

Scientists were fooled by this hoax for 40 years, until the weight of other finds finally drove some of them to take a close look at the skull itself, and find out it was a fake. One can hope things might work faster in this Internet age.

Nano Battery & Terminator

A couple here from my brother:

Nano-batteries


Although they don't necessarily follow Moore's law, batteries have still gotten smaller and more efficient as the years pass. The current go-to power cell of choice is the lithium-ion battery. It's already quite small as it is, but some scientists think it can get even smaller. How small? Try nanometers.

Self-repairing Robots.


Well, it looks like this is one aspect of fictional robotics that's starting to catch up with reality. Researchers at Arizona State designed a system that lets synthetics recreate the natural healing process found in organics. It uses shape-memory or mimetic polymers embedded with a network of fiber optics. The network senses any damage to the system, then delivers heat to the "wounded" area to repair it.

The Drake Equation

I did enjoy the program on BBC4 last night The Search for Life: The Drake Equation. If you can use I-player then I suggest you go take a look. But what is the Drake Equation? This explanation lifted from SETI lays it out nicely:

Is there a way to estimate the number of technologically advanced civilizations that might exist in our Galaxy? While working at the National Radio Astronomy Observatory in Green Bank, West Virginia, Dr. Frank Drake conceived a means to mathematically estimate the number of worlds that might harbor beings with technology sufficient to communicate across the vast gulfs of interstellar space. The Drake Equation, as it came to be known, was formulated in 1961 and is generally accepted by the scientific community.


N = R* fp ne fl fi fc L

where,

N = The number of communicative civilizations
R* = The rate of formation of suitable stars (stars such as our Sun)
fp = The fraction of those stars with planets. (Current evidence indicates that planetary systems may be common for stars like the Sun.)
ne = The number of Earth-like worlds per planetary system
fl = The fraction of those Earth-like planets where life actually develops
fi = The fraction of life sites where intelligence develops
fc = The fraction of communicative planets (those on which electromagnetic communications technology develops)
L = The "lifetime" of communicating civilizations


Frank Drake's own current solution to the Drake Equation estimates 10,000 communicative civilizations in the Milky Way. Dr. Drake, who serves on the SETI League's advisory board, has personally endorsed SETI's planned all-sky survey.

Moving no from the Drake Equation you then get to the Fermi Paradox:
 
The Fermi Paradox is the apparent contradiction between the high probability extraterrestrial civilizations' existence and the lack of contact with such civilizations.
 
In this program, I like how these two are covered. Consider how much of the EM spectrum there is to cover, how much our usage of radio has changed in just a few decades (AM to FM for example). Consider too a simple calculation: 100 billion (the number of stars in our galaxy) divided by that number of civilizations above.

Cellweld Inc.

Over here at Technology Review:

Today, a broken hip usually means surgery and extensive rehab. But what if all you needed was an injection and a shorter recovery period? That's the vision that inspires Thomas Webster, an associate professor of engineering at Brown University.


Webster has developed a nanomaterial that quickly solidifies at body temperature into a bone-like substance. This week, Brown announced a deal with medical device maker Audax Medical of Littleton, Massachusetts, to further develop the material and launch trials in animals.

The material contains the same nucleic acids as DNA, Webster says. Each molecule has two covalent bonds and links with other molecules to form a tube. Hence it's called a "twin-base linker." (Audax will develop it under the name Arxis.)

Well, not quite the same but getting there:

"Fascinated as he was by this exchange, Stanton could not concentrate on it. The robot now removed the splint and bandages from his arm with a scuttling of curved scalpels. This would have been bad enough in a proper hospital, but here? It then split his shirt sleeve and parted it … only, Stanton suddenly realised it wasn’t just his shirt that the machine had opened. He looked away quickly from the neatly snapped bone he could see there, and cringed at the sound of small tubes sucking away the blood that started to well up. There was movement next, but no pain, then came the reassuring drone of a bone welder. Stanton could not say he was impressed with Sylac’s bedside manner."

Another T for Tubb.

I did enjoy this series of books when I was younger, but by the time I'd read about twenty of them and the hero Dumarest had yet to find Earth, I was getting a bit fed up. I persevered as far as you see here then finally gave up.

Time to Stop Paying N.I.?

West Kent PCT tells us, "We are committed to delivering equality of opportunity for all service users, carers, staff and wider communities."

And now tells us:

From this month, patients who smoke and need planned surgery will have to complete a NHS Stop Smoking course before their operation.


Patients who are clinically obese or with a BMI (body mass index) of more than 30 will also have their surgery delayed and will have to carry out a weight loss programme.

So, if you smoke or you are too fat you don't get the surgery. It doesn't matter that this is a service you have been forced to pay for all your life.

Railgun

And thanks to Sean Price for sending me this one. I've seen this on You Tube but now apparently they've broken their own record. This was a 33 megajoule firing and: 'A single megajoule is roughly equivalent to a 1-ton car traveling at 100 mph. Multiple that by 33 and you get a picture of what would happen when such a weapon hits a target.' Ouch.

...

A theoretical dream for decades, the railgun is unlike any other weapon used in warfare. And it's quite real too, as the U.S. Navy has proven in a record-setting test today in Dahlgren, VA.


Rather than relying on a explosion to fire a projectile, the technology uses an electomagnetic current to accelerate a non-explosive bullet at several times the speed of sound. The conductive projectile zips along a set of electrically charged parallel rails and out of the barrel at speeds up to Mach 7.

Sonic Screwdriver

Thanks to my brother Bob for pointing this one out to me:

Science has always marched on and left speculative fiction looking like an antiquated throwback, but we never thought this would happen. Apparently researchers in Bristol University in the UK are studying how to use ultrasonic waves to manipulate objects, like say, screws, at a distance.

Rex Bionics

Well, seeing as after alibaba's comment about Rex Bionics someone from the company left a comment too, I finally went and had a good look at the site. Excellent stuff. It's quite surprising to realize we are still in an age when the inventor(s) in a shed can make a difference:

...

Rex, the Robotic Exoskeleton, is primarily the invention of two men, Richard Little and Robert Irving who have been close friends since they first met at high school over 20 years ago in Fort William, Scotland.


Sharing a love for cars and tinkering with machines, the two friends left school to study engineering and went on to work together at various times and in various climates throughout their careers until they both decided to emigrate to New Zealand in the early 1990s.

With already so much in common, the two friends also had first-hand knowledge of some of the obstacles and access issues faced many wheelchair users. Both have mothers who use wheelchairs, and when Robert Irving received a diagnosis for Multiple Sclerosis himself just over seven years ago, he understood that he might also need to use a wheelchair one day.

That was when the two friends and founders of Rex Bionics decided that they would use their engineering know-how to develop a realistic standing and walking alternative to wheelchairs.

Watching this video my first thought was about how slow these robotic legs are, but then realized that it's not just about being able to walk, since there's lots of health issues involved too: blood supply, muscle movement, bladder etc. I then have to wonder about other practicalities, like battery life, but it turns out that ain't such a probem. Two hours isn't going to take you along the length of the Penine Way, but the improvements in lifestyle could be huge. Then there are things like unit cost what with these bionic legs having '4700 parts and a complicated array of software' as compared to a wheelchair (with our NHS and NICE these things must be thought about in Britain), but you cannot make comparisons like that. I don't know if these things are quite well enough developed to enable a paraplegic to go to the toilet, but I'm guessing that possibility is not far away, then just think of the overall savings to society as a whole: no more houses needing to be built with wheelchair access, no more the necessity of toilets for the disabled.

However, they need to move faster, and they need to be designed in such a way that a person can sit and take a dump while wearing them. Sorry to be crude, but that's reality. Maybe if you're still checking in, Thomas, you can tell us about this sort of stuff?

Squishy Memristers and Diodes.

Damn but I love this shit:

Brain-Machine Interface

Neural Networks

Squishy Memristers and Diodes


So (Ju-Hee So) says these quasi-liquid components could one day be used to build bioelectronic circuits to provide connections between living tissue and computers, such as brain-machine interfaces. "People want to put information into the brain and read information out," she says. Such an interface might, for instance, allow an amputee to control a prosthetic limb the same way he would control his real limb—with just a thought. Similar devices made with conventional technology tend to be rigid and must be encapsulated to protect the electrical circuits from the moisture inherent in biology. So believes the materials her team is working with will be compatible with human tissue. Gallium salts, for instance, are injected into people to improve the contrast in scans of human lungs, and hydrogels have many biological uses. The devices might also be used as components in artificial neural networks, an application to which memristors are already being applied in earnest.

Science by Press Release

Seems to be par for the course nowadays: notoriety and money first with science coming in a distant second. Here's a bit more at WUWT about NASAs arsenic bug:

It seems that in their flawed zeal to get some press coverage, NASA again has egg of their faces, reminiscent of the Mars fossil microbe fiasco. It’s more “science by press release” gone wild. Slate.com has a scathing review of the fire that is raging in the microbiology camp over this press release:


“It would be really cool if such a bug existed,” said San Diego State University’s Forest Rohwer, a microbiologist who looks for new species of bacteria and viruses in coral reefs. But, he added, “none of the arguments are very convincing on their own.” That was about as positive as the critics could get. “This paper should not have been published,” said Shelley Copley of the University of Colorado…

Super Earth

Now, when NASA made that announcement, I was hoping for something like this:

"Ultimately the goal is to try to look for biosignatures," Bean said. "This work is another sort of milestone on this road. We're going directly towards that."


Looking at exoplanet atmospheres.

Be even better if they discovered biosignatures on one of these worlds, then managed to focus their instruments in time to pick up on the alien equivalent of Marconi.

Space Plane.

And space planes too. If The Departure was left for another year I think it would be getting out of date.
Thankfully no one has started building robot ‘shepherds’ for crowd control … have they?

...

When the Air Force launched its secret, robotic space plane this spring, military officials confessed that they weren't exactly sure when it was coming back. More than seven months later, the X-37B landed at Vandenberg Air Force Base in California, where it was met with Air Force personnel in SCAPE suits (self-contained atmospheric protective ensemble). They gave the robo-orbiter an initial once-over — and made sure the area was safe for humans, too.

Genome 10K

In The Departure I call this Gene Bank.

Robotic Trousers

Seeing this, I cannot help but think about the Wallace and Gromit 'The Wrong Trousers'. However, this sort of thing is seriously cool and is only going to get better. Reminds me of a piece I did for Nature Magazine in which I had a guy going to a museum to see one particular exhibit there: a wheelchair. Let's hope that sort of thing happens in the near future. I wonder if, in my lifetime, it'll cease to be compulsory to have wheelchair access to new-build houses?

An Israeli entrepreneur has invented robotic 'trousers' that can help paraplegics walk again.

...

Amit Goffer was paralysed in a car crash in 1997 and immediately set out to invent a device that could replace the wheelchair.

He has invented 'ReWalk': robotic trousers that use sensors and motors to allow paralysed patients to stand, walk and even climb stairs

Any Human Heart

We finally gave up on ‘Any Human Heart’ last night. This series was given big star ratings and really hyped beforehand and each time a new episode is shown we’re told it is a ‘powerful drama’. It has some excellent actors, great camera work and the sets are good too. However, it’s something we kept watching in the hope it was going to get interesting, and the problem is, at this point, in the third episode, it really should have been getting there. It isn’t; it’s boring.



This is the life story of a self-indulgent loser who is only interesting because of his setting and the people he met. He’s actually the kind of person you’d like to give a slab and tell to get his thumb out of his arse. The role , in fact, rather stretched Matthew Macfadyen’s full ‘drippy’ repertoire. This was supposedly a gripping big-budget adaptation that had all the grip of a pair of rubber tweezers.

...

So we turned over and watched ‘The nation’s favourite Abba Song’, which was an order of magnitude more enjoyable and interesting. I wanted to see ‘Fernando’ near the top though I did not expect it to win. Unfortunately it came in at number seven. Caroline then waited in the hope that ‘Dancing Queen’ would be the winner because when it was a hit she was precisely as the chorus describes. Her bottom lip was sticking out when it came in at number two, beaten by ‘Winner Takes it All’.

No Icebergs but Plenty of Ice.

Caroline, who has a fascination with the Titanic, booked us up to go to the O2 yesterday (O2 is of course a better name that ‘Millennium Dome’ and its associations with the laughable ‘millennium experience’ and about a billion in wasted money, for a fucking tent) but, with the weather we’ve been having, we were starting to have second thoughts. However, in the end I said let’s just go for it, so we did.




There was ice and snow everywhere and the road leading down to Althorne station was a sheet of ice (apparently roads to railway stations are not main routes that need gritting?), but if you don’t drive like a dick that wasn’t a problem. We parked at the station where only three cars occupied a car park that was normally full, and waited for out train, which was only a few minutes late. This would take us to Shenfield where we would then change for a train to Stratford, then hop on the Jubilee line heading for the O2.


However, the train stopped at Wickford and we then had to wait for three-quarters of an hour for another train to take us to Stratford. Luckily the pies and coffee there were cheap and good and, during the ensuing journey, some lunatics dressing up as super heroes (on their way to a party) were aboard to cheer us up.





At Stratford, because we hadn’t actually checked which stop we had to get off at to get to the O2 we did that old-time British thing and asked direction from a couple of policemen. They hadn’t got a clue and were in danger of putting us on the wrong course until another traveller put them right. We had to go to North Greenwich. From there to the O2 is just a short walk, and soon we reached the ‘Bubble’ where the Titanic artefacts display was located. Unfortunately I can’t put up any photographs because we weren’t allowed to take pictures inside. It was all pretty interesting and the American staff there were very informative and helpful. We spent an hour and three-quarters checking out the exhibits.




What they do, when you go in, is issue you with copy of a ticket for one of the Titanic passengers so, on the way out, you can see whether or not you survived. Both Caroline and I did survive, though she wasn’t in first class like me. They also take a photo against a green screen so on the way out you can buy a picture of yourself standing before the staircase Leonardo Dicaprio swanned down in the last scene of the film. Within the exhibition there is also a block of ice maintained at the temperature of the sea most of the passengers went into. Really, all they needed to do was turn off the heating.


After this we enjoyed a meal before heading home. On the way out I got a proper look at what I have to put forward as a contender for any ‘ugly building’ awards there might be.


Stratford was a nightmare. It took us half an hour to find a platform at which a train was due to head in the direction we wanted to go. Whilst waiting there we watched the train before ours arrive, full of people and with loads of people on the platform wanting to get on. It was like a scene out of some disaster movie with the crowds trying to escape the tsunami or the Martian war machines. When the doors finally closed, leaving a lot of passengers behind, I half expected to see severed limbs on the platform. When our train arrived the scenario was little different and, of course, you find that once aboard the train the problem stems from selfish dicks clustering about the door and not moving on down the carriage.

This train took us to Shenfield where similar scenes were being enacted. I was waiting for station staff to come out with machine-guns and leashed alsations, but station staff were notable by their absence. Here, and at Wickford station was where I started to feel the urge to lob a brick at any visible loudspeaker. The phrase, ‘we apologise for any inconvenience caused’ tends to cause one to doubt if there’s any contrition involved when it’s a recording being played ad nauseum. It then occurred to me then that a better name than the one painted on the sides of the trains might be ‘National Excuse’. I also noted how the phrase, ‘for your safety and comfort smoking is prohibited’ was always immediately followed by ‘for your safety and comfort this station has CCTV’ (note: I might have the precise wording wrong here, but you get the gist of it). Another one was something along the lines of, ‘due to the adverse weather conditions the platform is extremely slippery’. Well, no shit Sherlock.


When we finally got home I had to drive back from the station in second gear, never going above about 20 miles an hour. The car is in the garage now and I’m sitting next to the radiator, never to venture out again unless for essential supplies. You guys who have to go through that shit every day have my deepest sympathy.
