15th-century manuscript with 'alien' characters finally decoded

  15th-century manuscript with 'alien' characters finally decoded Scientists have harnessed the power of artificial intelligence to unlock the secrets of an ancient manuscript that has baffled experts. Discovered in the 19th century, the Voynich manuscript uses “alien” characters that have long puzzled cryptographers and historians. Now, however, computing scientists at the University of Alberta say they are decoding the mysterious 15th-century text.Computing science Professor Greg Kondrak and graduate student Bradley Hauer applied artificial intelligence to find ambiguities in the text’s human language. The first stage of the research was working out the manuscript’s language.

Artificial nests from Adobe (consisting of clay soil and straw, a building material) and foam, made to resemble the real thing, environmentalists have brought to the three Islands near Tasmania , which is home to albatrosses Thalassarche cauta (English name Shy Albatross — “shy, timid albacore”).

Researchers positioned the artificial nests just as the birds were starting to stake out nest sites. "While some species can physically relocate to more favourable environments or adapt in other ways, the biology of albatross make them particularly vulnerable to rapid negative changes.

More than 100 specially-built mudbrick nests were airlifted in July to the aptly-named Albatross Island in Bass Strait.

They were installed in areas where the birds' naturally-made nests were poor quality, often as little as a scrape on the rocks.

This breeding season's eggs have now hatched, with dozens of fluffy chicks calling the man-made nests home.

Specially built mudbrick and aerated concrete artificial nests , airlifted on to Bass Strait's Albatross Island in a trial program aimed at increasing the breeding success of the Tasmanian Shy Albatross , appear to have been Home .

"At this stage in the trial, the breeding success of pairs on artificial nests is 20 per cent higher than those on natural nests," biologist Rachael Alderman said.

"There are many more months ahead for all the chicks, and a lot can change, but so far it's very promising."

Shy albatross mums lay only one egg per year in late September that incubates for 72 days.

Artificial intelligence sparks hope -- and fear, US poll shows

  Artificial intelligence sparks hope -- and fear, US poll shows Americans are torn over the promise of artificial intelligence, a new poll showed Wednesday, expressing broad optimism about the emerging technologies but also fearing their negative impacts -- including job losses. The Gallup survey showed 79 percent of Americans say artificial intelligence has had a "mostly positive" or "very positive" impact on their lives thus far.At the same time, 73 percent said they expect the increased use of AI will eliminate more jobs than it creates and 63 percent predicted that new technologies and smart machines would widen the gap between rich and poor.

Both parents, who form a long-term pair, spend roughly five months feeding and caring for the chick.

It's thought half the chicks don't survive in the tough conditions.

"Albatross Island gets hit with wild weather," World Wildlife Fund (WWF) Australia's Darren Grover, who visited the island in December, said.

"The artificial nests were all intact but many of the natural nests were already starting to deteriorate."

The shy albatross, listed by the WWF as vulnerable, only nests off three remote Tasmanian islands - Albatross Island, Pedra Branca and Mewstone.

It's estimated there are 15,000 breeding pairs in the wild.

The trial is run by the state and federal governments, CSIRO, World Wildlife Fund and the Tasmanian Albatross Fund.

Portable Atomic Clocks Can Measure The Height of A Mountain .
Scientists hit the road with a high-precision clock hooked up to a trailer.In the experiment, published Monday in Nature Physics, scientists placed an optical lattice clock in an underground laboratory near the France-Italy border. An optical fiber link, a type of cable often used to transmit telephone signals, internet and cable TV, connected the clock to another type of clock for comparison in Torino, Italy. The two locations were about 3,280 feet apart in height, as data from the clocks were able to show.
