British treasure finders accused of piracy

Daily Mail - Science & tech

British archaeologists who discovered hundreds of artefacts from a cluster of 17th century shipwrecks in the Mediterranean Sea have had their cargo seized and been accused of an'illicit excavation'. Enigma Recoveries, which led an expedition into the Levantine Basin off the coast of Cyprus, found 12 shipwrecks filled with Chinese porcelain, jugs, coffee pots, peppercorns and illicit tobacco pipes. The ships and their priceless cargo, hailed as the'archaeological equivalent of finding a new planet' were recovered in ancient'shipping lanes' that served spice and silk trades from 300 BC onwards. But in a strongly-worded statement, the Cypriot government accused the company of being well known to both Cyprus and UNESCO for its'illicit underwater excavations' and its'violent extraction of objects causing destruction to their context'. Cyprus's Department of Antiquities accused the company of intending to sell the objects, as allegedly evident in documents filed with the United States Securities and Exchange Commission (NASDAQ).


12 shipwrecks uncovered in the east Med dating from 300 BC

Daily Mail - Science & tech

Archaeologists have found shipwrecks in the Mediterranean filled with hundreds of artefacts including Chinese porcelain, jugs, coffee pots, peppercorns and illicit tobacco pipes. A British-led expedition found a cluster of 12 ships on the sea bed, 1.2 miles below the surface of the Levantine Sea, using sophisticated robots. The ships were recovered in ancient'shipping lanes' that served spice and silk trades of the Greek, Roman and Ottoman empires, from 300 BC onwards. The ancient ships – including the biggest ever found in the Med – were unearthed in a muddy part of the eastern seabed between Cyprus and Lebanon, where remnants are often hard to find. The cluster of shipwrecks were found in the Levantine Basin in the east of the Mediterranean Sea.


Amazon says putting Alexa to work in your smart home's easy. Here's exactly what you need

USATODAY - Tech Top Stories

LOS ANGELES--The poster at one of the flashy new Amazon Books stores was inviting. "Smart Home Made Easy -- want to get started but don't know where to start?" I think most customers there would raise their hands and say, "That's me." Amazon's list put hard-to-understand tech geekdom into words we all get. What it didn't do was spell out the dollars that would be needed to be invested or how some of this stuff might work.


This virtual assistant looks like an anime girl trapped in a coffee pot

Engadget

Gatebox AI is an unusual virtual assistant that involves a projected CGI character kind-of trapped in a jar -- with voice controls! The sales pitch is that this virtual assistant will give the sensation of living with a fictional character, or according to how creator Vinclu Inc. words it, "your heroes". Which is fine, if your hero is a non-spectacular CGI anime character with blue hair and excessively submissive temperament. Behind the virtual idol/slave gloss, Gatebox AI's assistant functions approach a bare-bones Amazon Echo. According to the preorder site, Gatebox's debut character Hikari has the "ultimate healing voice" (uh huh) and the J-Pop AI will adjust to your daily rhythms, welcoming you home or sensing when you get up.
