RayModeler Sony's 360-Degree Autostereoscopic 3D Display

The RayModeler 3D display you’re seeing in this video is a prototype of the kind of device sci-fi storytellers have been dreaming up for years. LED light sources allow you to see an image from all angles, 360 degrees. Objects like faces and people appear realistic giving viewers a sense of depth because the left and right eyes are seeing different images.

Sony Introduces 360-Degree Autostereoscopic Display

At  Siggraph 2010 in Los Angeles, Sony showcased the prototype of its 360-degree Autostereoscopic Display. Autostereoscopic technology is considered to be the future of 3D, and does not require special 3D glasses. The device, known as the Ray Modeler, is cylindrical in shape and features LED light sources to enable viewing of full color volumetric objects from all directions. It also allows users to control the display’s orientation with hand gestures.

According to Sony, the system is the first display of its kind, featuring special LED light sources that show 360 unique, 24-bit color images in all directions. The user can even control the orientation of the display's content by using hand motions in proximity to the display (see video above).

Though the prototype seems far from being integrated into our everyday lives, Sony says that future iterations of their RayModeler will have many potential applications such as video entertainment, digital signage, education, museum displays, video games, advertising, and 3D telecommunication.

Toward Room-Temperature Superconductors

New research may solve key problem in physics

Binghamton University physicist Michael Lawler and his colleagues have made a breakthrough that could lead to advances in superconductors. Their findings were published this week in the British journal Nature.
Superconductors are materials – often but not always metals – that conduct electricity without resistance below a certain temperature. For decades, it was thought that these materials could conduct electricity only at temperatures far below freezing. In the last 20 years, however, scientists have discovered several compounds that superconduct at much higher temperatures.
In principle, a room-temperature superconductor could allow:
  • Electricity to travel with zero energy loss from power plants to houses.
  • High-speed trains to float on top of the superconductor.
  • Cell phone towers that could handle many cell phone carriers in high-population areas.
“It’s one of the most interesting problems that we have in physics,” Lawler said. “I believe that having a challenge at that level can help produce breakthroughs in science.”

How Superconducting Levitation Works


A pseudogap is a term from the field of high-temperature superconductivity which describes an energy (normally near the Fermi energy) which has very few states associated with it. This is very similar to a 'gap', which is an energy that has no allowed states. Such gaps open up, for example, when electrons interact with the lattice. The Pseudogap is a zone of the Phase diagram generic.

A pseudogap is only observed in hole-doped Cuprate superconductors. And isotope effect is only emerged on the boundary of phases between superconducting and pseudogap state.

Key Advance in Understanding ‘Pseudogap’ Phase in High-Tc Superconductors

May lead to ways to overcome barrier to room-temperature superconductivity in copper-oxides

This pattern shows the tunneling potential of electrons on oxygen atoms “north” and “east” of each copper atom (shown embedded in the pattern) in the copper-oxide layer of a superconductor in the pseudogap phase. On oxygen atoms north of each copper, the tunneling potential is strong, as indicated by the brightness of the yellow patches forming lines in the north-south direction. On oxygen atoms east of each copper, the tunneling potential is weaker, indicated by less intense yellow lines in the east-west direction. This apparent broken symmetry may help scientists understand the pseudogap phase of copper-oxide superconductors.

Scientists have been trying for some 20 years to understand why the low temperature at which copper-oxide superconductors carry current with no resistance can’t be increased to be closer to room temperature. Recently, scientists have focused on trying to understand and control an electronic phase called the “pseudogap” phase, which is non-superconducting and is observed at a temperature above the superconducting phase. But what form of electronic order (if any) characterizes the pseudogap phase has remained a frustrating and challenging mystery.
Across the entire copper-oxide crystal, the scientists found a remarkable difference in the electronic states associated with the mysterious pseudogap phase: The number of electrons able to “tunnel” to the microscope tip differed depending on the position of the oxygen atom relative to the copper atom. “Picture the copper atom at the center of the unit, with one oxygen to the ‘north’ and one to the ‘east,’ and this whole unit repeating itself over and over across the copper-oxide layer,” Davis said. “In every single copper-oxide unit, the tunneling ability of electrons from the northern oxygen atom was different from that of the eastern oxygen.”

The discovery of this asymmetrical behavior could be a breakthrough in understanding and controlling high-temperature superconductors because, historically, uncovering the reductions in symmetry responsible for other states of matter has led to huge advances in understanding and achieving control over those states. For example, discovery of the symmetries broken in liquid crystals eventually led to their control and everyday use in liquid crystal displays (LCDs).

Ecobot III -- Self-Sustaining Biomass Eating and Pooping Robot

Self-sustaining robot has an artificial gut (w/ Video)

(PhysOrg.com) -- UK researchers have developed an autonomous robot with an artificial gut that enables it to fuel itself by eating and excreting. The robot is the first bot powered by biomass to be demonstrated operating without assistance for several days. Being self-sustaining would enable robots of the future to function unaided for long periods.

logo Energy Autonomy: Ecobot

One goal of our work is to build energetically autonomous robots. For this, the Microbial Fuel Cell (MFC) technology is employed to extract electrical energy from refined foods such as sugar and unrefined foods such as insects and fruit. This is achieved by extracting electrons from the microbial metabolic processes. To be truly autonomous, robots will be required to incorporate in their behavioural repertoire actions that involve searching, collecting and digesting food. The robot will be designed to remain inactive until sufficient energy has been generated to complete its next task. This may prove to be a paradigm shift in the way action selection mechanisms are designed - (Project code-name:‘EcoBot’).

Holy crap! Scientists create pooping robot

The robot is powered by 48 small microbial fuel cells (MFCs) and moves along a steel track between sources of liquid food and water (see time-lapse video here).

The liquid food contains yeast extracts, minerals, and salt. The MFCs repeatedly digest and then recycle the food, producing hydrogen and electricity in the process. Once every 24 hours, the recycled food is pushed through a peristaltic pump into a litter tray, making EcoBot III the first poop-bot of its kind.

"Diarrhea-bot would be more appropriate," lab director Chris Melhuish told New Scientist. "It's not exactly knocking out rabbit pellets."

R136a1 The Biggest Star Ever

Most Massive Star Discovered—Shatters Record

Giant star discovered

A giant star has been discovered by astronomers who claim it to be the biggest star ever, and is 265 times bigger than the sun.

>European Organisation for Astronomical Research in the Southern Hemisphere

A 300 Solar Mass Star Uncovered

21 July 2010

Using a combination of instruments on ESO’s Very Large Telescope, astronomers have discovered the most massive stars to date, one weighing at birth more than 300 times the mass of the Sun, or twice as much as the currently accepted limit of 150 solar masses. The existence of these monsters — millions of times more luminous than the Sun, losing weight through very powerful winds — may provide an answer to the question “how massive can stars be?”

The University of Sheffield

NGC 3603 is located 22,000 light-years away from the Sun, and is a cosmic factory within which stars form quickly from the nebula´s ring of gas and dust. RMC 136a (more commonly known as R136a), another cluster of young, hot stars, is found within the Tarantula nebula, itself within the Large Magellanic Cloud, a neighboring galaxy to the Milky Way.

Stars with surface temperatures of over 40,000 C – more than seven times hotter than the Sun – were found, measuring tens of times larger and millions of times brighter. Many of these stars were born with a greater mass than they now posses, losing weight through very powerful winds, and models suggest that several were born in excess of 150 solar masses.

The most massive star ever found, R136a1 within the R136a cluster, has a current mass of 265 solar masses, and it is thought its birthweight was as much as 320 times that of the Sun. It is also the most luminous star ever found, close to ten million times that of the Sun. Within R136, only four stars out of an estimated 100,000 stars in the cluster weighed more than 150 solar masses at birth, yet they account for nearly half of the solar wind and radiation in the entire cluster.

In NGC 3603, two stars in a binary system were measured, to validate the models used. The stars A1, B and C in the cluster were all estimated to have weighed above or close to 150 solar masses at birth.

Google Buys Metaweb to Improve Search Results

Google said Friday that in an effort to improve these tricky types of search queries, it was buying Metaweb, a San Francisco start-up that says it makes Web sites smarter.


Google has recently added features to improve search results when people have specific questions. Type “Sarah Jessica Parker birthday” into Google, for instance, and on top of the search results, Google lists the actress’s birthday based on information it has pulled from other sites.
Metaweb will help Google do the same thing for more complicated queries, like “colleges on the West Coast with tuition under $30,000,” according to a blog post by Jack Menzel, director of product management at Google.

'Thinking' Plants

Can Plants Think?

In a new study, scientists have found a cabbage relative capable of remembering and responding to information

A Polish study showed plants send electrochemical signals in a way that can be likened to an animal nervous system. This image shows chemical reactions in leaves that were not exposed to light; they are reacting to a chemical signal from a leaf that was exposed.

Plants 'can think and remember'

The scientists discovered the "nervous systems" of Arabidopsis plants

Plants are able to "remember" and "react" to information contained in light, according to researchers.

Plants, scientists say, transmit information about light intensity and quality from leaf to leaf in a very similar way to our own nervous systems.

These "electro-chemical signals" are carried by cells that act as "nerves" of the plants.

In their experiment, the scientists showed that light shone on to one leaf caused the whole plant to respond.

And the response, which took the form of light-induced chemical reactions in the leaves, continued in the dark.

This showed, they said, that the plant "remembered" the information encoded in light.
The researchers used fluorescence imaging to watch the plants respond

Thinking plants
What was even more peculiar, Professor Karpinski said, was that the plants' responses changed depending on the colour of the light that was being shone on them.


"So the plants perform a sort of biological light computation, using information contained in the light to immunise themselves against diseases that are prevalent during that season."

Discovery of light (quantum) memory and photoelectro physiological signalling in plants

Evidence for Light Wavelength-Specific Photo-Electro-Physiological Signaling and Memory of Excess Light Episodes in Arabidopsisa

Magdalena Szechyńska-Hebda, Jerzy Kruk, Magdalena Górecka, Barbara Karpińska and Stanisław Karpiński*

This work examines light-wavelength specific electro-physiological signaling and cellular light memory in Arabidopsis. Animals have their network of neurons, synapses, electro-physiological circuits and memory, but plants have their network of chloroplasts (connected by stromules), photo-electro-physiological signals transduced by bundle sheath cells, and cellular light memory.




Bitcoin P2P Currency

Open source innovation: Bitcoin

Alternative currencies for e-commerce have been attempted many times, but never one quite like Bitcoin. Its creator, Satoshi Nakamoto, has dubbed it a "cryptocurrency," because it relies on public/private key cryptography to facilitate electronic trading in a completely anonymous, secure, peer-to-peer fashion.

Bitcoin P2P Cryptocurrency

Bitcoin is a peer-to-peer network based digital currency. Peer-to-peer (P2P) means that there is no central authority to issue new money or keep track of transactions. Instead, these tasks are managed collectively by the nodes of the network. Advantages:
  • Transfer money easily through the Internet, without having to trust middlemen.
  • Third parties can’t prevent or control your transactions.
  • Bitcoin transactions are practically free, whereas credit cards and online payment systems typically cost 1-5% per transaction plus various other merchant fees up to hundreds of dollars.
  • Be safe from the instability caused by fractional reserve banking and bad policies of central banks. The limited inflation of the Bitcoin system’s money supply is distributed evenly (by CPU power) throughout the network, not monopolized by the banks.
Bitcoin is an open source project created by Satoshi Nakamoto, and is currently in beta development stage. Bitcoin development is hosted at SourceForge.

Anonymous internet banking

Anonymous Internet Banking is the name given to the proposed use of strong financial cryptography to make electronic bank secrecy (or more precisely pseudonymous banking) possible. The bank issues currency in the form of electronic tokens that can be converted on presentation to the bank to some other currency. This concept has a long history in which free banking institutions have issued their own paper currency often backed by a physical commodity.
Examples of anonymous internet banking services that have already been implemented include:
  • Bitcoin: open source peer-to-peer electronic cash system that's completely decentralized, with no central server or trusted parties.
  • eCache: an anonymous bank operating over the Tor network.
  • Pecunix: an (optionally?) anonymous digital gold currency.
  • Yodelbank: an anonymous bank built on top of various digital gold currencies which ended operations during November 2005.


A peer-to-peer, commonly abbreviated to P2P, is any distributed network architecture composed of participants that make a portion of their resources (such as processing power, disk storage or network bandwidth) directly available to other network participants, without the need for central coordination instances (such as servers or stable hosts).[1] Peers are both suppliers and consumers of resources, in contrast to the traditional client–server model where only servers supply, and clients consume.

The First Malaria-Proof Mosquito

Malaria: No Ordinary Mosquito Bite

Malaria-proof mosquito engineered

Scientists in the US have succeeded in genetically engineering a malaria-resistant mosquito. 

The researchers, from the University of Arizona, introduced a gene that affected the insect's gut, meaning the malaria parasite could not develop.

They report the advance, which also reduced the insects' lifespan, in the journal PLoS Pathogens.

They say that the ultimate goal is to introduce malaria-resistant mosquitoes into the environment.

Discovery News

Malaria-Proof Mosquito Created

This major breakthrough could prevent millions of people from being infected with the life-threatening disease.

The scientists focused on the parasites as they develop by targeting the Akt gene. Previous studies have shown that Akt affects a mosquito's longevity, immune system and digestion -- all of which could affect the bug's susceptibility to malaria.

As a result, the team engineered a special version of the Akt gene into the eggs of Anopheles stephensi mosquitoes.

After infecting the mosquitoes with Plasmodium parasites and allowing them to develop, the scientists examined the mosquitoes. They found no trace of the malaria parasites in mosquitoes that had the amped up version of Akt.

Exactly how Akt eliminates malaria in mosquitoes is unknown.

The First Malaria-Proof Mosquito

Michael Riehle, holding genetically altered mosquitoes, and his team work in a highly secure lab environment to prevent their study subjects from escaping.
Riehle is a professor of entomology in UA's College of Agriculture and Life Sciences and is a member of the BIO5 Institute.

Riehle's team used molecular biology techniques to design a piece of genetic information capable of inserting itself into a mosquito's genome. This construct was then injected into the eggs of the mosquitoes. The emerging generation carries the altered genetic information and passes it on to future generations.

Department of Entomology
Research Program
Mosquito borne diseases impact the lives of billions worldwide. Malaria alone infects at least 300 million people annually, resulting in 1 to 3 million deaths, mostly children. Other diseases spread by mosquitoes, such as dengue and West Nile encephalitis, continue to broaden their range. Unfortunately, traditional mosquito control methods such as insecticide treatment have become less effective as mosquitoes develop resistance to these compounds. Thus, it is critical that we develop novel means of controlling these pests. Towards this goal, my lab is attempting to better understand the mosquito’s physiology and use this knowledge to reduce the mosquito’s ability to transmit disease.
