Caligae
Caligula's statue will come back home
http://www.newnotizie.it/2011/07/13/ritrovata-la-statua-di-caligola-in-trono/
Emperor Caligula's statue is coming back home to Nemi. It was the provincial team of the Guardia di Finanza in Rome, led by General Ignacio Gibilaro, to retrieve it, during an police action to protect the national artistic heritage. According to Giuseppina Ghini, head of the Museum at Nemi, this staue is a piece of extraordinary beauty, discovered in a previously unknown archaeological site. The statue, after restoration, will be soon bach home in the Museum of Nemi.

DNA transistor
Solid-state nanopores are a core element of next-generation single molecule tools in the field of nanobiotechnology, most prominently in the area of DNA-sequencing technology. Researchers at the IBM T. J. Watson Research Center have recently introduced a nanopore-based DNA sequencing platform, which they call a DNA transistor. Thin-film electrodes are integrated into the nanopore device for electrically interacting with translocating DNA. They have now shown that TiN electrodes inside a nanopore can be passivated and completely shielded against electrochemical deterioration even when extreme voltages are applied."
electrochemical impedance spectroscopy
Rapid, sensitive, accurate, miniaturized and inexpensive biosensors are highly desirable for assisting clinical medical diagnosis. Researchers based at National Chiao Tung University, Taiwan, have developed such a portable bio-sensing platform to detect intermolecular interactions using nanogold-enhanced electrochemical impedance spectroscopy (EIS)."

A giant mirage on a Chinese river
"It looks like any other city skyline with skyscrapers, a few mountains and trees -- except it isn't real.
The giant mirage appeared across the skyline in East China earlier this month after heavy rainfall and humid conditions covered the Xin’an River. As mist settled over the river at dusk, tall buildings appeared to rise from nowhere, leading residents in nearby Huanshan City to speculate that the vision may be a "vortex" to a lost civilization."

Royal scenes dated back to Dynasty Zero
“Dr. Maria Carmela Gatto (Director of Aswan-Kom Ombo Archarological Project) made a discovery at Nag el-Hamdulab site (North west of Aswan) of the oldest graffiti shows a King wearing the Upper Egypt headgear(crown) with a group of royal scenes dated back to dynasty zero.” Said Dr. Zahi Hawass. “The find shows many hieroglyphic graffiti and the first drawings shows a complete royal celebration looks exactly like what was known in the different Pharanoic eras, showing the Pharaoh wearing his white crown accompanied by Horus followers or the royal court.”Hawass added."

Ice Age Art
L’arte più antica d’America trovata su un osso di mammut, LUGLIO 4, 2011. di Aezio
"I ricercatori dello Smithsonian Institution e dell’Università della Florida hanno confermato la veridicità di un misterioso manufatto scoperto in Florida nel 2006: un frammento osseo, di circa 13.000 anni fa, con incisa l’immagine di un mammut o un mastodonte. Questa incisione è l’esempio più antico e l’unico conosciuto di arte dell’era glaciale a raffigurare un Proboscidato nelle Americhe. La ricerca del team è stato pubblicata sul Journal of Archaeological Science."

A far quasar
The brilliant beacon, named ULAS J1120+0641, is powered by a black hole with a mass two billion times that of the Sun. Located at a redshift – a term relating to astronomical distances – of 7.1, its light has taken 12.9 billion years to reach us. The next most distant quasar is seen at 870 million years after the big bang, or a redshift of 6.4, although gamma ray bursts have been detected at greater distances of 8.6 and 8.2 redshifts."

Who and where
"The principal mission of the Ministry of State for Antiquities, previously known as the Supreme Council of Antiquities, is to protect and promote the cultural heritage of Egypt, both independently and in cooperation with national and international organizations. To achieve its goals, it formulates and implements all policies concerned with antiquities; issues guidelines and permits for the excavation, restoration, conservation, documentation, and study of sites and monuments; and manages a country-wide system of antiquities museums."

An ancient Egyptian federation
An ancient Egyptian federation
As reported by Aristide Malnati, federalism had been developed for the first time in the ancient Egypt. This is a conclusion after analysis of archaeological and historical elements, lasted for 30 years during the systematic excavations on the site of Balat, Dakhla Oasis (200 km due west of Luxor). The period was that of the Sixth Dynasty (2300-2200 BC). The excavation is lead by the French archaeologist Georges Soukiassian.
Balat is considered the oldest Egyptian village. It was the most powerful center in one of the richest regions in Egypt, particularly during the Sixth Dynasty. Here lived the Governors of Oasis, having wide autonomy from the king and a real possibility to influence the decisions of the national policy.

A "Mobius" graphene
How small can these shapes be? In December 2003, German chemists made a molecular Mobius strip out of a benzene-like ring modified with a belt-like carbon structure. Since then, various groups have produced increasingly bizarre Mobius-type molecules, including one that can switch back and forth from a Mobius to an ordinary strip when zapped with light.
Of course, the obvious choice of material with which to make Mobius molecules is graphene. But this particular trick has eluded chemists, an omission that clearly irks. Now Douglas Galvao from the Universidade Estadual de Campinas in Sao Paolo, Brazil, and buddies have decided to grip the bull by the horns and calculated the properties that Mobius carbon might have."New form of "Mobius" carbon predicted - Technology Review

Hot quarks break free
"Physicists in the US, India and China have calculated that quarks and gluons can break free from their confinement inside protons and neutrons at a temperature of around two trillion degrees Kelvin – the temperature of the universe a fraction of a second after the Big Bang. The researchers arrived at this figure by combining the results of supercomputer calculations and heavy-ion collision experiments. They say that it puts our knowledge of quark matter on a firmer footing."

Wrinklons
"A new quasiparticle called the "wrinklon" could help explain why materials as diverse as graphene and household curtains wrinkle in much the same way – despite their very different length scales. The particle has been introduced by researchers in Belgium, France and the US as a result of measurements on a wide range of materials on length scales from micrometres to metres. While the work may not lead to more attractive curtains, wrinkles do turn out to affect the electronic properties of graphene and the analysis could therefore influence the development of graphene-based devices."
Voyager mission at the edge of the solar system
"Recent data from the spacecraft have shown a gentle decrease in the velocity of the solar wind at the heliopause – the outer boundary of the heliosheath – not the abrupt discontinuity predicted by current theories. Also, scientists looking at other data from both Voyager 1 and Voyager 2 have found that the magnetic field in the heliosheath is a tumultuous foam of magnetic bubbles, as compared to the graceful arcs of magnetic field lines they had expected."

On sunspots and solar flux
by AC Sparavigna
The paper shows the recurrence and cross recurrence plots of three time series, concerning data of the solar activity. The data are the sunspot number and the values of solar radio flux at 10.7 cm and of solar total irradiance, which are known as highly correlated. To compare the series, the radio flux and irradiance values are monthly averaged. Recurrence plots display the oscillating behaviour with remarkable features. Moreover, cross recurrence plots help in identifying time lags between the sunspot number maximum and the maximum of radio or irradiance signals, in circumstances where the data values are highly dispersed. Image processing is useful too, in enhancing the monitoring. An interesting behaviour is displayed by cross recurrence plots of irradiance, which are not symmetric with respect to the line of identity.
Hygroscopic properties of volcanic ash

Volcanic ash is hygroscopic
Water vapor adsorption is the main proceess controlling ash hygroscopicity
The results can be parameterized in a simple correlation for use in models
"Limited observational data exists on the physical interactions between volcanic ash particles and water vapor; yet it is thought that these interactions can strongly impact the microphysical evolution of ash, with implications for its atmospheric lifetime and transport, as well as formation of water and ice clouds. ...The hygroscopicity of the ash particles is quantified by their ability to uptake water and nucleate into cloud drops under controlled levels of water vapor supersaturation. Evidence presented strongly suggests that ash uptakes water efficiently via adsorption and a simple parameterization of ash hygroscopicity is developed for use in ash plume and atmospheric models."
