### Why Scientists Think Completely Unclassifiable and Undiscovered Life Forms Exist

Agreed. The classic example of fire fits almost all definitions of life. The reason fire isn't 'alive' is because it doesn't contain the ability to evolve via natural selection via some sort of informational content.

### Why Do Contextual Ads Fail?

May be this is where the 'internet of things' could be useful. You can get a cheap/free kettle that serves up ads on a little LCD screen telling you about different products you can boil.

### How Deep Does the Multiverse Go?

This is something called the metric expansion of space. The metric value is changing at a local level where the measurement is taken. I think it is misleading to talk about space as a dimension moving at some speed, because speed is really distance per unit time. the expansion of space is just space per space changing. We tend to embed our explanations as if the universe expanded from a point on a piece of paper, it doesn't really work that way, the paper in a sense is being generated as it goes along. The speed of light is just some measured velocity value that happens to be pretty close to c when we measure it at various places around the universe, light goes through the metric of space. The metric of space doesn't really say much about what that speed is. So c just goes along the metric as the metric is generated.

### The Higgs Boson Should Have Crushed the Universe

Could we be saved by M-Theory or Brane cosmology then? The Higgs boson energy may get dissipated in someway by leaking into the 'bulk'? http://en.wikipedia.org/wiki/B...

### Bitcoin Security Endangered By Powerful Mining Pool

Isn't the block chain what makes it decentralised? (281 comments)

Isn't the point of bitcoin is that the block chain is decentralised? i.e. everyone has a copy of it? does it matter who mines the coins as long as the coins end up distributed around? also can't the bitcoin protocol just be tweaked by the developers or something?

### Zuckerberg's \$100 Million Education Gift Solved Little

not knowing what education is for (335 comments)

I think he would have been better to use the money to set up training programs for skill sets that are useful to society, particularly infrastructure aspects like plumbing, electricians etc. May be use the money to set up in school programs for really specific things like programming, or target specific types of students to figure out what they might excel in.

### Getty Images Makes 35 Million Images Free For Non-Commercial Use

Re:That's not "why it doesn't work"....that's you (66 comments)

I just tried this on my site and the main problem I have is that their caption for 'getty images' is really too big. It needs to be just a simple caption one line style. I think it is sufficient to have the image clickthru to getty.

### Will You Even Notice the Impending Robot Uprising?

If robots are everywhere then it's possible (246 comments)

Imagine a scenario of several factories that are built by robots. The maintenance of the building is handle by robots too. For example an air conditioning unit breaks down, an oil leak etc etc. There is a robot that comes along to deal with it. The computer that controls these functions monitors it all and responds. The factory has its own robot guards, makes its own weapons etc. It needs more iron ore to make parts? It has a copy of all the maps of geological surveys and sends out a robotically controlled truck and excavator to dig up the ore. It gets the ore and brings it to the robot controlled smelting plant and so on. But this is probably not likely for another few hundred years.

### What Wi-Fi Would Look Like If We Could See It

It's hard to see waves unless it reflects (120 comments)

This is imagery in the article is really very misleading. What would be more meaningful to set the visible spectrum to black ( so no colour for the buildings) and then set some colours for each individual wifi transmitter. In fact it would look more like an image of Earth from space with only the lights showing, but rather than light it would be a microwave image. It would probably show only the faintest outline of buildings as the RF is absorbed creating an odd looking set of structures. But to 'see' the RF you would also need to set up a kind of 'RF reflective' fog particles in the scene to view the reflections ( a bit like the way you need dust to see a laser beam in the dark)

### Apple Updates MacBooks and Mac Pro Desktop With Haswell, "Unified Thermal Core"

This is very much like borg technology it seems, though it lacks the green glow. But actually this is a pretty nice prosumer device. I suspect that the entry level machine with 4 cores will be what Apple is keen to sell, I suspect the low end spec machine ( similar to current low spec on the Apple store) but probably a few hundred dollars cheaper. This will allow apple to sell more Apple Displays too. I actually think this is a clever strategy to get people who want to play high end graphics intense games. As far as expandability, I also think those days are over. The daisy chaining ability would reduce the actual number of wires at the back too. Pretty sure there is some kind of tower of Thunderbolt external adapeter drives you can sit next to it. No doubt a third party will create a matching cylinder that you can slide other things into like SDDs graphics cards drives etc and only needing one cable into the main cylinder.

### Sequoia Supercomputer Sets Record With 'Time Warp'

Re:so.. how much power does it draw? (39 comments)

Isn't the solution to this to use qubits? Just use a quantum computer techniques to 'transmit' the data? Though the computer probably would need to be running at some crazy cold temperature.

### Physicists Attempting To Test 'Time Crystals'

Re:What does this have to do with time? (231 comments)

It might be that time is important in the sense that it provides an asymmetry in that there is a direction to time when you observe an energy change. The idea that energy goes somewhere else, decays to somewhere else ( like heat) in a particular time direction. For example at time A energy goes from one level to another , to time point B. The experiment may suggest that under those special conditions time is symmetrical, there is no before or after event or that they can interchange with no energy changes. Just my interpretation here.

### Physicists Attempting To Test 'Time Crystals'

I think the idea is that these atoms would do the equivalent of bob up and down without any external energy input. It's kind of analogous to observing an astronomical object moving in an orbit in the absence of a central massive object. That's how I would interpret it. Because this is happening at a super cooled state you could not extract energy from this system because that would disturb it ( ie Heisenberg's uncertainty principle comes into play). I speculate this effect may occur but it would not have any real large macroscopic relevance.

### Majorana fermions as a testable candidate for dark matter

ceview (2857765) writes "Majorana fermions are their own anti particles and may form so called anapoles to potentially be good candidates for testing dark matter theories. This is according to work done by Vanberbilt University in a recently published paper.

### Do 'time crystals' exhibit perpetual motion?

ceview (2857765) writes "So this story on Wired seems to have got lots of people a bit confused. The experimental set up is incredibly delicate (Bose Einstein Condensate) so it implies this perpetual motion effect can't really be used to extract energy. What is your take on it? It can't really upend anything because at a quantum level things behave weirdly at the best of times.

### Is human DNA encoded by extra terrestrial intelligence?

ceview (2857765) writes "Well yes according to what discovery.com is reporting. Vladimir I. shCherbak of al-Farabi Kazakh National University of Kazakhstan, and Maxim A. Makukov of the Fesenkov Astrophysical Institute think human DNA contains data that can't be 'evolved' via Darwinian natural selection; so they suggest it as being of extra terrestrial origin."

### An orbital solar death ray idea from WWII

ceview (2857765) writes "So from an old forgotten article in Life Magazine that as reported in news.com.au " US Army technical experts came up with the astonishing fact that German scientists had seriously planned to build a “sun gun".
A giant orbital mirror that would focus light on targets below and burn or boil away whatever was in the way."

### How could swarms of robots help humanity?

ceview (2857765) writes "Researchers at Sheffield Centre for Robotics have demonstrated that a swarm of 40 robots can carry out simple fetching and carrying tasks. This is done by grouping around an object and working together to push it across a surface. They believe that this could provide opportunities for us mere humans to harness such power to do all sorts of things like safety — what like catching falling workers perhaps?

### Millions of people could be labelled mentally ill with new DSM

ceview (2857765) writes "According to an opinion piece in the BMJ " The new somatic symptom disorder in DSM-5 risks mislabeling many people as mentally ill"

Allen Frances, Chair of the current (DSM-IV) task force notes that " by eliminating the requirement that somatic symptoms must be "medically unexplained" he explains. In DSM-5, the focus shifts to "excessive" responses to distressing, chronic, somatic symptoms with associated "dysfunctional thoughts, feelings, or behaviours."

And goes on to note that " Somatic symptom disorder captured 15% of patients with cancer or heart disease and 26% with irritable bowel syndrome or fibromyalgia, and had a very high false-positive rate of 7% among health people in the general population.""

### Self healing chips can handle a few laser blasts

ceview (2857765) writes "Caltech researchers have been tweaking their designs of self-healing microchips with the hopes of them working to save power if they not being damaged by laser blasts.

" Its prototype power amplifier chip has a dedicated circuit and sensors that can change actuators in microseconds if there's damage, re-optimizing the connections on the spot." Which sounds pretty impressive. But can some explain how this actually works? It sounds like something from Star trek voyager."

### Processed meat means early death for some

ceview (2857765) writes "The BBC reports that eating too much processed meat is a ticket for an early death. " If you don't eat yer meat, you can't have any pudding!" Yes Pink Floyd reference there. Anyway,I think this was reported a while back somewhere else about 6 months ago. Is this report saying anything new? Well this study is includes half a million people across Europe. According to BBC report

" One in every 17 people followed in the study died. However, those eating more than 160g of processed meat a day — roughly two sausages and a slice of bacon — were 44% more likely to die over a typical follow-up time of 12.7 years than those eating about 20g.""

### UK government provides funding for European Extremely Large Telescope E-ELT

ceview (2857765) writes "The Guardian reports that the UK Gov is to contribute £88 million for building a telescope with a diameter of 39 metres and made of 798 separate segments. This E-ELT has potentially more collecting area than all the other telescopes in the world. "The E-ELT will have almost as much light collecting area as all the telescopes ever built, put together," said Professor Niranjan Thatte of Oxford University. So what other things will this be able to see? what spin off technologies could be developed?"

### Culture defines sense of time, for time related things.

ceview (2857765) writes "People seem to prefer ads placed that have a consistent placement according to the sense of time they are brought up with. It seems to be more to do with reading from left to right or right to left though. From the research: ""Whether a product's image is placed on the left or the right of an advertisement matters for products promising results occurring over time (weight loss aids or anti-aging creams) or products that are valued because they are old or new (antique furniture, modern art, wine, new technologies)," write authors Boyoun (Grace) Chae and JoAndrea Hoegg (both University of British Columbia)""
