Humanity has entangled stuff bigger than photons; The Biggest "Spooky" System Ever Seen: 4 Entangled Ions (Jun 2009) and Entangled diamonds , big enough for the eye to see (Dec 2011). We haven't managed the information transportation part with anything other than photons though but we're doing well on distance; quantum key transmitted wirelessly 144km.

Original Joshua Lewis (the researcher) blog posting: Rethinking the value of Scrabble tiles

I've developed an open source package called Valett for determining letter valuations in word games based on statistical analyses of corpora. In addition to calculating the frequency of each letter in a corpus, Valett calculates the frequency by word length and the incoming and outgoing entropy for each letter's transition probabilities. One can then weight these properties of the corpus based on the structure of the game and arrive at a suggested value for each letter..


Submission + - LG aims to beat Apple's Retina display (

angry tapir writes: "LG Display has introduced a 5-inch full HD LCD panel for smartphone displays — the highest resolution mobile panel to date. The widescreen panel is based on AH-IPS (Advanced High Performance In-Plane Switching) technology and has a 1920-by-1080 pixel resolution or 440 pixels per inch (ppi), according to LG. That compares to Apple's Retina display, which has 264 ppi on the new iPad and 326 ppi on the iPhone 4S."

The test dives all went well past the 8,000 meter mark and I'm sure the sponsors wanted the deepest point moniker attached to the venture. There are many mountains more challenging to climb than Everest but everyone want to go to the highest none the less.

All along he's said that it's about the science and having reached the deepest point I'm sure they'll be visiting those places that maximise the science. James Cameron says he does not want this dive to the deep to be a one-off, and wants to use it as a platform for ocean exploration.

Having reached the deepest point there is no where marked off limits and there are several other ventures out there on the same Race to the bottom of the Ocean quest.

Perhaps try the BBC article: Mercury has been 'dynamic world'

"Many scientists believed that Mercury was much like the Moon - that it cooled off very early in Solar System history, and has been a dead planet throughout most of its evolution," said Maria Zuber, from the Massachusetts Institute of Technology (MIT).

"Now, we're finding compelling evidence for unusual dynamics within the planet, indicating that Mercury was apparently active for a long time."

Dr Zuber and her colleagues used laser measurements from Messenger to map out a large number of impact craters, and found that many had tilted over time. This suggests that geological processes within the planet have re-shaped Mercury's terrain after the craters were created.

A process called polar wander can cause geological features to shift around on a planet's surface.

In theory, the process of convection going on within the mantle could drive such changes. But Dr Zuber said this would be unusual in Mercury's case, because the mantle is so thin.

Another potential explanation could be that features on the surface were distorted as the planet's interior cooled and contracted. This fits in with observations that some surface features on Mercury have been exposed to high levels of stress.

The idea behind this is that is can be manufactured from recycled materials more effectively, it doesn't mention how recyclable the product is itself.

Compared to plastic, the materials needed to make Paper PP Alloy are easy to retrieve.

The mixture of different plastics causes the major issues for effective plastic recycling.

Are you sure it's the glasses? "Have you ever noticed that the picture in your local movie theater is too dark or grainy? The Boston Globe does some good ol' fashioned investigative reporting to find the culprit.

OTOH James Cameron did insist on double the normal number of projectors for the premier of Avatar to ensure he got the colour he wanted. It's a shame that subsequently no one else gets to see it like that.

Result of GPL enforcement: More work available to the public.

Result of shortening copyright: More work available to the public.

The difficulty is the big studios don't want this otherwise there will be plenty of entertainment experiences for us all to enjoy without paying our tithe to them. To keep making money, churning out the same experiences over and over, the old experiences need to be as hard to access as possible.

A few excerpts from Kodak develops: A film giant's self-reinvention (Feb 2010) seem to suggest they just couldn't transition fast enough rather than became irrelevant.

... every Oscar winner for Best Motion Picture in the past 81 years has used Kodak film... 65 percent of Kodak's business now comes from business-to-business products and 70 percent of them are digital. Hayzlett's message is simple: every aspect of Kodak's business has been reinvigorated by winds of change.

The usual explanation is that Kodak failed to see the approach of digital.

In fact, Kodak was more than ahead of its competitors: it invented the digital camera -- even though it lacked the foresight to exploit it.


Submission + - High Resolution Global Topographic Map of Moon (

stuckinarut writes: NASA's Lunar Reconnaissance Orbiter (LRO) has released the highest resolution near-global topographic map of the moon ever created.

Our new topographic view of the moon provides the dataset that lunar scientists have waited for since the Apollo era,” says Mark Robinson, Principal Investigator of the Lunar Reconnaissance Orbiter Camera (LROC) from Arizona State University in Tempe. “We can now determine slopes of all major geologic terrains on the moon at 100 meter scale. Determine how the crust has deformed, better understand impact crater mechanics, investigate the nature of volcanic features, and better plan future robotic and human missions to the moon.”
