Era de Pando, Peru

"Ancient Village in Liberec Department, Peru. This is a late Archaic site, thought to be created by the same Supe Culture responsible for the larger nearby site, Caral. The site includes and adobe pyramid and about two dozen buildings. A comparison aerial view on Google maps of both Caral and Era de Pando shows the similarities in architectural layout."

Caral, in Peru, the oldest town in the New World

"In 2001, the oldest town in South America was officially announced. Dating to 2600 BC, it pushed back the date for the “first town” with one millennium. What is even more intriguing, is that the town of Caral has pyramids, contemporary with the Egyptian Pyramid Era....The ancient pyramids of Caral predate the Inca civilization by 4000 years, but were flourishing a century before the pyramids of Gizeh. No surprise therefore that they have been identified as the most important archaeological discovery since the discovery of Machu Picchu in 1911" by Philip Coppens, read more http://www.philipcoppens.com/caral.html

Abstract "During a series of experiments performed between 1907 and 1911, the Italian physicist Domenico Pacini (Marino 1878-Roma 1934), at that time researcher at the Central Bureau of Meteorology and Geodynamics in Roma, studied the origin of the radiation today called “cosmic rays”, the nature of which was unknown at that time. In his conclusive measurements in June 1911 at the Naval Academy in Livorno, and confirmed in Bracciano a couple of months later, Pacini, proposing a novel experimental technique, observed the radiation strength to decrease when going from the surface to a few meters underwater (both in the sea and in the lake), thus demonstrating that such radiation could not come from the Earth’s crust. Pacini’s conclusive experiment was performed, and the results published (in Italian), one year before the famous balloon experiment by Victor Hess, who found the ionization rate to increase with height. While Hess is today celebrated as the discoverer of cosmic rays, Pacini’s work was largely overlooked. Hess was awarded the Nobel Prize in Physics in 1936, two years after the death of Pacini, who had become a full professor of Experimental Physics at the University of Bari and the Director of the local Institute of Physics. The discovery of cosmic rays —a milestone in science— involved several scientists in Europe and in the United States of America and took place during a period characterized by nationalism and lack of communication. Historical, political and personal facts, embedded in the pre- and post-World War I historical context, might have contributed to the substantial disappearance of Pacini from the history of science. This article aims to give an unbiased historical account of the discovery of cosmic rays; in the centenary of Pacini’s pioneering experiments, his work, which employed a technique that was complementary to, and independent of that of Hess, will be duly taken into consideration. A translation into English of  three fundamental early articles by Pacini is provided in the Appendix. "

3D screen with voxels

"Researchers at Southampton University are using the holographic-style display to design a flawless-quality communication system that comes closer to the impression that users are in the same room.
... This ‘HoloVizio’ screen is made up of tiny elements called voxels (rather than pixels) that can represent depth information. Each voxel emits multiple beams of light that vary in colour and intensity depending on which direction they travel."

Bent-Core Liquid Crystals: Their Mysterious and Attractive World,  by Hideo Takezoe, and Yoichi Takanishi, Jpn. J. Appl. Phys. 45 (2006) 597 [Abstract] [Full Text PDF Free ]
Bent-Core Liquid Crystals: Their Mysterious and Attractive World
Hideo TAKEZOE and Yoichi TAKANISHI
Structures and properties of liquid crystalline phases formed by bent-core molecules are reviewed. At least eight phases designated as B1–B8 have been found, being unambiguously distinguished from phases formed by usual calamitic molecules due to a number of remarkable peculiarities. In addition to B1–B8 phases, smectic A-like phases and biaxial nematic phases formed by bent-core molecules are also reviewed. The most attractive aspects of this new class of liquid crystals are in polarity and chirality, despite being formed from achiral molecules. The bent-core mesogens are the first ferroelectric and antiferroelectric liquid crystals realized without introducing chirality. Spontaneous chiral deracemization at microscopic and macroscopic levels occurs and is controllable. Moreover, achiral bent-core molecules enhance system chirality. The interplay between polarity and chirality provides chiral nonlinear optic effects. Further interesting phenomena related to polarity and chirality are also reviewed. [DOI: 10.1143/JJAP.45.597]

Shale gas

From Wiki "Shale gas is natural gas produced from shale. Shale gas has become an increasingly important source of natural gas in the United States over the past decade, and interest has spread to potential gas shales in Canada, Europe, Asia, and Australia. One analyst expects shale gas to supply as much as half the natural gas production in North America by 2020."
Study says natural gas use likeky to double, NYTimes, http://www.nytimes.com/2010/06/25/business/energy-environment/25natgas.html?_r=1&src=busln

Dal Sole24ore "L'Eia ha ritoccato le stime sulle riserve nazionali di shale gas - il metano che si ricava da antiche e stratificate formazioni rocciose – più che raddoppiandole. Così, quegli Stati Uniti già abbastanza ossessionati dalla dipendenza dal petrolio d'importazione, scoprono con sollievo di essere una potenza nel gas: secondo l'Eia, nel 2035 il 45% del fabbisogno americano verrà dalle rocce sedimentarie."

American mastodon

Mastodons  were large tusked mammal species of the extinct genus Mammut which inhabited Asia, Africa, Europe, North America and Central America from the Oligocene through Pleistocene, 33.9 mya to 11,000 years ago. The American mastodon is the most recent and best known species of the group.
The American mastodon, Mammut americanum,  lived from about 3.7 million years ago until about 10,000 BC. It was the last surviving member of the mastodon family. It is known from fossils found ranging from present-day Alaska and New England in the north, to Florida, southern California, and as far south as Honduras and El Salvador.

Cryogenic energy storage

Cryogenic energy storage plant could provide valuable back-up | News | The Engineer
"The UK’s first cryogenic power storage plant, which uses liquid nitrogen to store and release energy, is scheduled to open next month. Its operator, Highview Power Storage, said the system could provide a relatively cheap way of storing power, particularly from intermittent sources such as wind turbines, to better match the supply of electricity to demand.The pilot facility near Slough has been providing electricity to the National Grid since April last year by evaporating liquid nitrogen stored at -200ºC to drive turbine generators. Highview is now installing equipment to re-liquefy and compress the nitrogen using electricity from the grid, creating a closed cryogenic system that can store energy at times of surplus and release it when it is needed, while re-using the cold air exhaust."

Physicists create 'anti-laser'

Physicists create 'anti-laser' - physicsworld.com

"In a fascinating case of physics being turned on its head, a group of researchers at Yale University in the US has created an "anti-laser" that almost perfectly absorbs incoming beams of coherent light. The invention is based on a theoretical study reported last summer in which Douglas Stone and his Yale colleagues claimed that such a system could be possible in a device that they call a coherent perfect absorber (CPA). Instead of generating coherent light beams with a laser, the devices absorb incoming coherent light and convert it into either heat or electricity."
