Le Trung a 33 year old Canadian chemistry graduate has invented a working female android.     

The ability to read and converse in English and Japanese, answer questions, access internet information, do math problems, recognize common objects and make upper body and hand gestures; she can feel the difference between gentle touching and sharp pressure on her body and even object to the latter. 

Aiko’s cognitive system consists of unique software featuring AI, speech, reading, math, color vision, hearing, temperature & pressure sensors, OCR, face and common object recognition. The android also asks for information when it doesn’t understand and stores that information for future use; i.e. it learns.

Potential applications are as a home servant or company receptionist. The remarkable thing is that Trung has had no commercial backing; he has developed the concept in his spare time at home. He accepts donations at his Project Aiko web site.

Next steps include developing facial expressions, capacity to taste and full mobility with the lower body.

Hi-tech CT and tomography scans reveals further details of the celestial computer including a handy dial indicating the 4 yearly timing of the ancient version of the Olympic Games.

The Antikythera Mechanism was recovered in 1901 by sponge divers off the Greek island of Antikythera from a 1^st Century  BC Roman wreck.

It was taken to the National Archaeological Museum in Athens where after some months it split apart, revealing internal gearwheels.

I saw the mechanism as a teenager in 1974, which was about the time that serious scientific research began in order to understand the construction and purpose of the mechanism.  Erich von Däniken popularized the mechanism in the 70s by proposing that it originated via alien visitors in his book ‘Chariots of the Gods’.

The Antikythera Mechanism was in fact a kind of portable planetarium computing device arranged in a carriage clock-type, case.  The find consists of 4 main and 15 smaller fragments originally containing at least thirty bronze gearwheels with precise, 1.5 mm triangular teeth.  Studies have shown that the tooth counts of the surviving gears can be explained in terms of calendar cycles calculated from common multiples of solar and lunar cycles.  The device was capable of predicting movements of the Earth, Moon, Sun and the timing of eclipses.

The mechanism dimensions are c. 13″ x 7″ x 4″  with opening front and back panels revealing dials and output data for whichever date was selected by mechanical winder. The device design exhibits astonishing sophistication, e.g. it corrected for subtle irregular lunar variations, using epicyclic gearing theory.  In addition to the date and the positions of the sun and the moon in the zodiac, it is also likely that the device predicted the position of some, or all of the 5 known planets (wandering stars) at the time.

Recent work has revealed details of internal inscriptions, despite two thousand years under water.  The researchers used a 12 ton, HP polynomial texture mapping machine as well as Microfocus X-ray CT techniques in order to detect the engraved script within the now corroded together, mechanism. 

By carefully analysing the  CT scan slices with sophisticated software, many internal inscriptions have been painstakingly deciphered. This work has led to knowledge regarding specific calendar calculation methods e.g. the 19 year Metonic cycle vs the 76 year Callippic cycle as well as the discovery of a new ‘Olympiad dial’.  The ancient Greeks held four primary, inter-regional athletic events, at rival Cities in honor of specific patron deities; these games were often referenced when indicating important dates. The olympiad dial displayed which Pan-Hellenic games would be held in any given year, e.g. the ancient Olympic Games, held every 4 years in Olympia.  

There have been several citings of such machines in ancient texts but until recently it was not imagined that the design and manufacture of such a device was so advanced. No comparable mechanism was seen again for c. 1000 years.

Red coloration is a known, testosterone-dependent signal of male quality in a variety of animals.  A statistical study of  ‘Association Football’ (Soccer) teams in England over a 55 year period showed that red teams had the best home record, with significant differences in percentage of maximum points achieved. The researchers, Russell Hill and Robert Barton, had  previously shown that in the 2004 summer Olympic games for four events (Boxing, Tae kwon do, Greco-Roman wrestling and Freestyle Wrestling) competitors randomly assigned a red uniform had a 55% win percentage.

Other studies found that referees scoring video bouts gave competitors higher scores when uniforms were digitally altered to be red.

No modern violin maker or ‘Luthier’ has been able to match the qualities of the classical Cremonese violin-making families of Amati, Stradivari and Guarneri who flourished from c. 1600 to 1750. Only about seven hundred Stradivarius violins still exist from these times and they are the most sought after musical instruments in the world.  

Enthusiasm for these instruments is not merely for the instrument’s antique or novelty value; the sound of these violins is universally accepted as far superior to modern violins, in terms of quality of expressiveness and projection.

A new study by Berend C. Stoel and Terry M. Borman of Leiden University Medical Center in the The Netherlands & Borman Violins, in Fayetteville, Arkansas, has found that one of the key factors may be original raw material properties of the Maple and Spruce woods that were used.  In particular, the density, or more specifically the variability of wood density at the growth ring level throughout the violin.

The consistency of growth ring density is related to consistency of the tree growth rates from the Spring through Autumn and modern woods do not seem to match the evenness of growth found in the 17^th century wood.

If the density consistency is a major factor, then the reason for it, is as yet, not fully explained; variation in density may reflect differences in stiffness distributions, which could impact vibrational efficacy or may modify sound radiation via altered sound damping properties of the wood.

A part of the mystery of the Cremonese masterpieces may have revealed itself but don’t expect modern violin makers to be reproducing this effect any time soon.  The climatic reasons for subtle variations in growth ring density are not properly understood and would be practically impossible to replicate.

After decades of insisting that mercury amalgam fillings are perfectly safe, the US FDA makes a U-turn and issues a health warning. 

The FDA web site has dropped its reassuring language from its website, substituting: “Dental amalgams contain mercury, which may have neurotoxic effects on the nervous systems of developing children and fetuses.” It adds that when amalgam fillings are “placed in teeth or removed they release mercury vapor”, and that the same thing happens when chewing.

The new warning means that despite consumer suspicions, millions of people have previously been erroneously reassured  into accepting health risks from the amalgam.  These potentially include: heart conditions, Alzheimer’s, high blood pressure, infertility, fatigue disorders and neurotoxic effects on developing children and fetuses.

Paleontologists have discovered fossil remains of parrots on the Isle of Mors in the northwest of Denmark.

Could this be a sub-species of the Norwegian Blue? anticipated in the 70s by Cleese and Palin.  Certainly deceased, bereft of life and possibly ‘pinin for the fjords’ which hadn’t yet formed.

Professor Frank Fish became intrigued with the curious bumps or tubercles on the pectoral flipper of the Humpback Whale, and decided to investigate .

Fish, of West Chester University of Pennsylvania, discovered through use of wind tunnels, that the irregular serrations were no anomaly.  The flipper exhibited a much steeper stall angle compared to a smooth shape.  Each tubercle apparently redirects and channels fluid over the flipper, creating vortexes that improve lift.

Fish has formed a company called WhalePower, which recently licensed the design for a new line of fans and wind turbines.  The blades realize 20 percent decreases in energy use and a significant drop in noise levels.

It just shows what 30 million years of evolutionary field testing can provide.

According to ‘the standard model’, the universe is isotropic or, allowing for random granularity, the same consistency in all directions. Three new separate studies are now indicating an uneven pattern.  If this is confirmed, it would need a major change to current theory of the Universe and its early formation.

Initially Kate Land and João Magueijo of Imperial College London noticed an uneven pattern in the distribution of cosmic microwave background radiation, ( the cosmic hiss left over from, and providing evidence for, the big bang ).  Land & Magueijo have named this pattern, somewhat geekishly, ‘the evil axis’.

 Subsequently, Damien Hutsemékers of the University of Liège in Belgium analyzed 355 quasars and found that randomness of the polarization of their light becomes more ordered than expected near the proposed axis.

More recently, Michael Longo of the University of Michigan in Ann Arbor analyzed 1660 spiral galaxies and found that the rotation of most galaxies near the proposed axis, is also extremely unlikely to be random.

Ideas for the cause of this phenomenon are already being mooted, including the possibility that the early period of ‘inflation‘ – a now widely accepted theory of super accelerated expansion soon after the big bang, may have involved an uneven bulge.

 Scientists have made the world’s smallest diamond ring (5 millionths of a meter across), which could play a key role in the future of computing.

The ring was laser carved from diamond crystal by Phyicists at the University of Melbourne, and will help researchers build quantum computers.  Apparently it also comes in a nice, circular presentation holder.

Quantum computing is an exciting new computing concept, still in its infancy that will e.g. theoretically be able to crack ciphers requiring astronomical numbers of guesses, in seconds rather than years.

The 50-centimetre-long carving shows hunters in traditional Eskimo boats, along with whales and harpoons.

Russian Research Institute for Cultural and Natural Heritage in Moscow says the newfound ivory carving was determined to be 3,000 years old by radiocarbon dates on the soil in which it was embedded. The previous oldest solid evidence for whaling is some 2,000 years old.  The same site also yielded heavy stone blades, and remains from a number of dead whales.

Reported last week, at a meeting of the Society for American Archeology in Vancouver, Canada.
