If you zoom in between the palm trees you will see two parakeets. We have a flock of ten that live in the 5300-5500 block of Leopard St here in Corpus Christi, Tx.

This is so true. But if it were we would never have prejudices against others..... Yeah like that'll ever happen. *facepalm *
 
Marie Curie

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.

On July 4, 1934, Marie Curie, the first woman to win a Nobel Prize, and the only person to win Nobel Prizes in two different fields of science, passed away.  +Maria Popova shares the story of her obituary in the New York Times here: http://goo.gl/MESla

In addition to highlighting Curie's scientific discoveries (over the course of a multipage story), it also noted the conditions under which Curie conducted her research:

"M. and Mme. Curie, not being able to pursue their chemical experiments in a schoolroom which had been placed at their disposal, arranged for these in a sort of abandoned warehouse opposite their atelier. In this place, with its asphalt floor, its broken and patched glass roof, hot in Summer, heated by a cast-iron stove in Winter, they performed their wonderful work."

"The equipment consisted of some old and worn deal tables, upon which Mme. Curie prepared the material for the production of radium. She was laboratory chief assistant and handy boy at the same time. In addition to her intellectual labor it was frequently necessary for her to perform severe manual toil. On many an afternoon she stirred in a great caldron with a heavy iron rod the molten mass of the radioactive products, reaching home at evening exhausted by fatigue but delighted to see that her labors had led to a luminous product of concentration."

News from the real world of science! Some of these are real breakthroughs in the pursuit of nanotechnology as well as quantum computing! Neato!!!
 
SciTech #ScienceSunday Digest 22 - 7th Jul 2013
Mechanosynthesis prototype, MEMS atom painter, biological computer and synthetic ribosome, optical switch and twisted data.

1. DNA Nanomachine for Precise Enzymatic Control.
A DNA Origami approach has resulted in the creation of a controllable tweezer-like nanomachine made out of DNA http://phys.org/news/2013-07-tiny-tweezers-precision-enzymes.html. One end of the DNA structure has an enzyme attached and the other end has a reaction centre; the addition of one short DNA sequence causes the ends of the tweezers to spread apart and the addition of another short DNA sequence causes the ends to contract, bringing the enzyme and reaction centre together to perform the reaction in a controlled manner. Such nanosystems enabling precise positional control of chemical reactions is something long talked about by Eric Drexler for example. Imagine the group scaling this up to large arrays of these machines on a surface, able to mass-produce any desired chemical feedstock in a rapid and controlled fashion. I think this is a significant step on the road towards the full promise of nanotechnology, and yet it was so under-reported. 

2. Atomic Calligraphy: MEMS That Write Nanoscale Structures.
A novel MEMS-based mask writer has been developed that allows nanoscale structures to be directly written without photoresists or other expensive techniques http://www.nanowerk.com/spotlight/spotid=31159.php. The MEMS device acts like a shutter that, in effect, spray paints with atoms (one-at-a-time if desired); the team believe this approach will allow them to build atomic-scale devices using cost-effective manufacturing approaches. When combined with a MEMS-based evaporator and sensors to measure temperature and deposition rate this should yield a “Fab on a Chip”.

3. Building a Computer with Biological Parts: A Biological Microprocessor.
Our very own +Gerd Moe-Behrens describes in great detail how to build a general purpose biological microprocessor assembled from biological parts http://hplusmagazine.com/2013/07/03/the-biological-microprocessor-or-how-to-build-a-computer-with-biological-parts/. As Gerd states: such a system consists of biological parts building an input / output device, an arithmetic logic unit, a control unit, memory, and wires (busses) to interconnect these components. The promise and significance of a biocomputer is that it can be used to monitor and control a biological system. This will be a truly profound capability once realised. 

4. Twisted Light Boosts Optical Data Transmission.
A new fiber optic technology has been demonstrated that utilises circularly polarized (or twisted light vortices) to transmit data at 1.6 terabits per second http://www.photonics.com/Article.aspx?AID=54269. The proof-of-concept achieved this over a distance of 1km and by being able to combine multiple frequencies that did not interfere with each other. While faster transmission speeds have been achieved in special environments such as free space, this new system can be rolled out to significantly increase broadband speeds. 

5. Hyper-Magnetically-Sensitive Molecular Chains.
New and much more sensitive magnetic sensors should be possible with a new device that houses special molecular wires within ordered nanometer channels in zeolite crystals http://phys.org/news/2013-07-molecular-chains-hypersensitive-magnetic-fields.html. The molecules have a diameter of about one nanometer, roughly the same as the crystal channels that confine them, and conduct electricity until an external magnetic field disturbs their alignment. It is thought a similar mechanism is at play in migratory birds that sense the geomagnetic field to navigate. 

6. Creating & Transplanting a Rudimentary Liver from IPS Cells.
In this latest tissue engineering demonstration researchers took adult cells, turned them into stem cells, coaxed these cells to assemble and form little rudimentary liver buds, then transplanted these buds into mice whose own livers had been shut down and showed that the transplanted buds executed most of the functions of a liver and kept the mice alive http://www.technologyreview.com/news/516706/a-rudimentary-liver-is-grown-from-stem-cells/. The possibility for human therapy is obvious, especially because the technique is applicable to other tissues, but problems remain with scale-up issues in creating large enough volumes of the cells to provide a viable therapy. 

7. Building Better Graphene Nanoribbons.
Making electronic and spintronic components out of graphene nanoribbons moved a step closer with new fabrication methods that preserve edge magnetism via uniform attachment of suitable molecules along the edges of the ribbons http://www.nanowerk.com/spotlight/spotid=31128.php. This preserves the band-gap of the graphene nanoribbons and makes the material easier to work with. Graphene’s heat conduction properties have also been shown to reduce the temperatures of computer chips by up to 25% http://www.chalmers.se/en/news/Pages/Graphene-provides-efficient-electronics-cooling.aspx

8. Nanotube Catalyst Outperforms Platinum.
Covering carbon nanotubes with an iron compound produces a new catalyst that outperforms conventional platinum catalysts in applications for fuel cells and metal-air batteries http://phys.org/news/2013-07-scalable-carbon-nanotube-based-catalyst-outperforming.html. The material not only achieves significant cost and efficiency improvements but also demonstrated a much greater lifecycle with improved durability. 

9. Building An All-Optical Transistor.
An all-optical switch or transistor has been created that is controlled by a single photon http://web.mit.edu/newsoffice/2013/computing-with-light-0704.html. A single photon can cause the switch - a double nanoscale mirror system - to turn “off” or “on” allowing photons to pass or be blocked by the switch. All optical computer chips promise to be significantly faster than conventional chips, and at one photon ber bit of information this system would be significantly more energy efficient. Because the system relies on a single photon there are other very interesting and potentially transformative / disrupting possibilities too: (i) the possibility to detect a photon without destroying it, and (ii) a key enabling technology for a genuine quantum computer where photons in a superposition result in these switches / logic gates also being in a superposition. 

10. Ribosomes Synthesised for The First Time.
While previous attempts have failed this new method succeeds in synthesising and assembling ribosomes that are fully functional and replicate within cells http://www.northwestern.edu/newscenter/stories/2013/06/mimicking-living-cells-synthesizing-ribosomes.html.  The work is seen as a critical step towards unraveling the systems biology of ribosome biogenesis, constructing minimal cells from defined components, and engineering ribosomes with new functions. For example, ribosomes take genetic code in the form of RNA and use that to produce proteins of a defined sequence and structure; one might want to engineer a ribosome to take a different chemical code to RNA or to build chemical sequences and structures different to amino acids and proteins.

Denzel just went past awesome!
 
Remember this next time you walk up to the ticket window of your local movie theater with $10 in your hand. The Media (Accidentally?) missed this one!!!! Please read this: The troops oversees would like you to send it to everybody you know. Subject: Denzel Washington, and Brooks Army Medical Center. Don't know whether you heard about this but Denzel Washington and his family visited the troops at Brook Army Medical Center , in San Antonio , Texas, (BAMC) the other day. This is where soldiers who have been evacuated from Germany come to be hospitalized in the United States , especially burn victims. There are some buildings there called Fisher Houses. The Fisher House is a Hotel where soldiers' families can stay, for little or no charge, while their soldier is staying in the Hospital. BAMC has quite a few of these houses on base, but as you can imagine, they are almost filled most of the time. While Denzel Washington was visiting BAMC, they gave him a tour of one of the Fisher Houses. He asked how much one of them would cost to build. He took his check book out and wrote a check for the full amount right there on the spot. The soldiers overseas were amazed to hear this story and want to get the word out to the American public, because it warmed their hearts to hear it. The question is - why do: Britney Spears, Lindsay Lohan, Paris Hilton, Tom Cruise and other Hollywood fluff make front page news with their ridiculous anticsand Denzel Washington's Patriotism doesn't even make page 3 in the Metro section of any newspaper except the Local newspaper in San Antonio . A true American and friend to all in uniform! This needs as wide a distribution as we can create. Please share it!

True +Krystel Rivera , but when you renounce scientific fact for something that is a belief vs fact then one tends to wonder wheather your trying to impose your religious views on the rest of the country. Then one wonders why he was chosen for this particular committee post . He should be removed forthwith! And as to politicians in general they all are egoist,who's only goal in life is NOT the betterment of the country, but their selves. Remember power corrupts, absolute power corrupts absolutely.

Sounds plausible to me.
 
A Twitchy Tale

Why do babies twitch in their sleep? It turns out that sleep twitching happens in virtually every mammal, from puppies to squirrels. +Virginia Hughes writes a well-sourced article for National Geographic explaining how these movements may be building blocks that help the developing motor system learn more complex behaviors.
