SyNAPSE: IBM Cognitive Computing Project – Hardware
A Cognitive Information Superhighway
”IBM’s brain-inspired architecture consists of a network of neurosynaptic cores. Cores are distributed and operate in parallel. Cores operate—without a clock—in an event-driven fashion. Cores integrate memory, computation, and communication. Individual cores can fail and yet, like the brain, the architecture can still function. Cores on the same chip communicate with one another via an on-chip event-driven network. Chips communicate via an inter-chip interface leading to seamless scalability like the cortex, enabling creation of scalable neuromorphic systems.”(http://www.research.ibm.com/cognitive-computing/neurosynaptic-chips.shtml#fbid=15Zz4zjXf0H)
Bringing Computing to the Data
”A video camera on Hoover Tower at Stanford University is looking down at the plaza, below. A simulated network of IBM TrueNorth chips takes in the video data and locates interesting objects. Objects might look interesting to the system because they are moving or have a different color or texture than the background. The system then further processes those portions of the interesting video to determine what the objects are. It is trained in several specific categories, such as buses, cars, people, and cyclists. In a monitoring application, the camera would only need to communicate when it found an interesting object, rather than continually streaming video to a central location.”(http://www.research.ibm.com/cognitive-computing/neurosynaptic-chips.shtml#fbid=15Zz4zjXf0H)
DARPA SyNAPSE Program (artificialbrains.com Jan 11, 2013):” SyNAPSE is a DARPA-funded program to develop electronic neuromorphic machine technology that scales to biological levels. More simply stated, it is an attempt to build a new kind of computer with similar form and function to the mammalian brain. Such artificial brains would be used to build robots whose intelligence matches that of mice and cats. SyNAPSE is a backronym standing for Systems of Neuromorphic Adaptive Plastic Scalable Electronics. It started in 2008 and as of January 2013 has received $102.6 million in funding. It is scheduled to run until around 2016. The project is primarily contracted to IBM and HRL who in turn subcontract parts of the research to various US universities. ..”

100-Plus HIV/AIDS Researchers On MH17: ‘Devastating Impact’
The seeker after the truth is not one who studies the writings of the ancients and, following his natural disposition, puts his trust in them, but rather the one who suspects his faith in them and questions what he gathers from them, the one who submits to argument and demonstration, and not to the sayings of a human being whose nature is fraught with all kinds of imperfection and deficiency. Thus the duty of the man who investigates the writings of scientists, if learning the truth is his goal, is to make himself an enemy of all that he reads, and, applying his mind to the core and margins of its content, attack it from every side. He should also suspect himself as he performs his critical examination of it, so that he may avoid falling into either prejudice or leniency.(イブン・アル=ハイサム, 965-1040.https://en.wikiquote.org/wiki/Alhazen)
NIH mulls rules for validating key results (31 July 2013):”…In a 2011 internal survey, pharmaceutical firm Bayer HealthCare of Leverkusen, Germany, was unable to validate the relevant preclinical research for almost two-thirds of 67 in-house projects. Then, in 2012, scientists at Amgen, a drug company based in Thousand Oaks, California, reported their failure to replicate 89% of the findings from 53 landmark cancer papers….
In science, the integrity of data is the foundation for credible findings. I am deeply saddened by all that has transpired, and after thoughtful consideration of the errors presented in the RIKEN report and other concerns that have been raised, I have agreed to retract the papers. Although there has been no information that cast doubt on the existence of the stimulus-triggered acquisition of pluripotency (STAP) cell phenomenon itself, I am concerned that the multiple errors that have been identified impair the credibility of the manuscript as a whole. I am encouraged by recent news which suggests that Minister Hakubun Shimomura and RIKEN President Ryoji Noyori will allow sufficient time to replicate the core STAP cell concept that my brother Martin and I originally hypothesized, and trust that it will be verified by the RIKEN as well as independently by others.

Several critical errors have been found in our Article and Letter (http://dx.doi.org/10.1038/nature12969), which led to an in-depth investigation by the RIKEN Institute. The RIKEN investigation committee has categorized some of the errors as misconduct (see Supplementary Data 1 and Supplementary Data 2). Additional errors identified by the authors that are not discussed in RIKEN’s report are listed below.
(1) Figure 1a and b in the Letter both show embryos generated from STAP cells, not a comparison of ES- and STAP-derived chimaeric embryos, as indicated in the legend.
(2) Extended Data Fig. 7d in the Article and Extended Data Fig. 1a in the Letter are different images of the same embryo and not, as indicated in the legends, a diploid chimaera embryo and tetraploid chimaera embryo.
(3) There is an erroneous description in Fig. 1a in the Letter. The right panel of Fig. 1a is not a ‘long exposure’ image at the camera level but a digitally enhanced one.
(4) In Fig. 4b of the Letter, STAP cell and ES cell are wrongly labelled in a reverse manner.
(5) In the Article, one group of STAP stem cells (STAP-SCs) was reported as being derived from STAP cells induced from spleens of F1 hybrids from the cross of mouse lines carrying identical cag-gfp insertions in chromosome 18 in the background of 129/Sv and B6, respectively, and that they were maintained in the Wakayama laboratory. However, further analysis of the eight STAP-SC lines indicates that, while sharing the same 129×B6 F1 genetic background, they have a different GFP insertion site. Furthermore, while the mice used for STAP cell induction are homozygous for the GFP transgene, the STAP-SCs are heterozygous. The GFP transgene insertion site matches that of the mice and ES cells kept in the Wakayama laboratory. Thus, there are inexplicable discrepancies in genetic background and transgene insertion sites between the donor mice and the reported STAP-SCs.
We apologize for the mistakes included in the Article and Letter. These multiple errors impair the credibility of the study as a whole and we are unable to say without doubt whether the STAP-SC phenomenon is real. Ongoing studies are investigating this phenomenon afresh, but given the extensive nature of the errors currently found, we consider it appropriate to retract both papers.
ダンゴムシの意思決定 Decision-making in pill bugs The 27th Annual Conference of the Japanese Society for Artificial Intelligence, 2013 (PDF link):ダンゴムシの交替性転向反応は,BALM 以外にも走触性(Hughes, 1989)や記憶(Kupfermann, 1966)など,複数の機構が並列的に作用して実現されている可能性が高く(右田・森山, 2005),これらを統合して転向方向を選択する意思決定機構の存在が予想される.著者らは,ダンゴムシ個体にT字路を連続して遭遇させた実験(Moriyama, 1999)でしばしば観察された,転向方向の変更(図1)は,ダンゴムシの意思決定が顕著に反映された現象なのではないかと考えている.転向方向の変更は,個体がT字路において転向した後,次のT字路へ達するまでに停止し,後進で直前のT字路へ引き返し,前回の転向とは逆の方向へ転向することで達成される(図1).後進を含むこの一連の行動はBLAMでは説明できないため,転向方向の変更は別の機構の働きによって現れると考えられる.
R. N. HUGHES. Mechanisms for turn alternation in woodlice (Poreellio Beaber): The role of bilaterally asymmetrical leg movements. Animal Learning & Behavior.1985, 13 (3), 253-260 (PDFリンク):Along with results of the other experiments, this result in particular supported an explanation for woodlouse alternation based on bilaterally asymmetrical leg movements (BALM)arising from the negotiation of forced turns. Such asymmetry is seen as biasing an animal to turn in the opposite direction to a preceding forced turn.
R. N. HUGHES. TURN ALTERNATION IN WOODLICE (PORCELLIO SCABER). Anim. Behav ., 1967, 15, 282-286 (PDFリンク):As the persistence of the tendency seems to depend on time, it might be rewarding to seek a neural controlling mechanism involving the establishment of a short-term memory trace somewhere in the central nervous system (as suggested by Kuferman, 1966), or else, at a more peripherallevel, greater inhibition of neural components of the limbs adjacent to the outer wall of a maze turn i.e. the limbs that have to `walk further’ .
In sex-reversed cave insects, females have the penises (ScienceDaily April 17, 2014): “Although sex-role reversal has been identified in several different animals, Neotrogla is the only example in which the intromittent organ is also reversed,” says Kazunori Yoshizawa from Hokkaido University in Japan.

In weird Brazilian cave insects, male-female sex organs reversed (Reuters Thu Apr 17, 2014 12:09pm EDT): “Evolution of novelties like a female penis is exceptionally rare. That’s why I was really surprised to see the structure,” entomologist Kazunori Yoshizawa of Japan’s Hokkaido University said by email. Yoshizawa said that although sex-role reversal has been documented in several different types of animals, these insects are the sole example in which the “intromittent organ” – the male sex organ – is reversed, Yoshizawa said.
