Large vessels are fishing 55 percent of world’s oceans

by Kerry SHERIDAN Agence France-Presse MIAMI, United States (AFP) — More than half the world’s oceans are being fished by large commercial vessels, particularly from China, according to the first view from space of global fishing practices published Thursday. The report in the journal Science used satellite data to track industrial fishing and found that 55 percent of the world’s oceans — and possibly more — are being exploited by big fishing operations. Some parts […]

Space-X lobs Spanish military satellite into orbit

WASHINGTON, United States (AFP) — Elon Musk’s Space-X sent a Spanish military satellite into orbit Thursday in a hitch-less liftoff from California, extending the private space company’s record of successful launches. Space-X, which proved the utility of its massive Falcon Heavy rocket earlier this month, put up the Paz imaging satellite and two of the company’s own test internet communications satellites on a smaller Falcon 9 rocket. “Successful deployment of PAZ satellite to low-Earth orbit […]

Twitter sets crackdown on automated ‘bot’ accounts

by Glenn Chapman Agence France-Presse SAN FRANCICSCO, United States (AFP) — Twitter announced Wednesday a crackdown on accounts powered by software “bots” which can artificially amplify a person or cause and which have been accused of manipulating the social network during the 2016 US election.

Weekend stargazer wins supernova ‘cosmic lottery’

by Marlowe Hood Agence France-Presse PARIS, France (AFP) — To say that Victor Buso was in the right place at the right time may be the biggest understatement in the history of stargazing. By pure luck, the amateur astronomer from Rosario, Argentina snapped the first before-and-after images ever captured of a star as it explodes in a brilliant flash of light and morphs into a supernova. Astronomers call this pivotal moment “shock breakout,” and have […]

Scientists set off to explore new Antarctic ecosystem

LONDON, United Kingdom (AFP) — A team of international scientists led by the British Antarctic Survey set off on Wednesday to explore a mysterious marine ecosystem that has lain hidden under an ice shelf for up to 120,000 years. The BAS said that an iceberg known as A68 broke off from the Larsen Ice Shelf in July 2017, revealing a section of seabed measuring 5,818 square kilometers (2,245 square miles) — nearly four times the […]

Kin of ‘world’s ugliest animal’ among fish hauled off Australia abyss

SYDNEY, Australia (AFP) — More than 100 rarely seen fish species were hauled up from a deep and cold abyss off Australia during a scientific voyage, researchers said Wednesday, including a cousin of the “world’s ugliest animal” Mr Blobby. Scientists spent a month last year on a vessel off the country’s eastern seaboard surveying life lurking up to 4.8 kilometres (2.9 miles) below the surface, using nets, sonar and deep-sea cameras. Over 42,000 fish and […]

Top experts warn against ‘malicious use’ of AI

by Marlowe Hood Agence France-Presse PARIS, France (AFP) — Artificial intelligence could be deployed by dictators, criminals and terrorists to manipulate elections and use drones in terrorist attacks, more than two dozen experts said Wednesday as they sounded the alarm over misuse of the technology. In a 100-page analysis, they outlined a rapid growth in cybercrime and the use of “bots” to interfere with news gathering and penetrate social media among a host of plausible […]

Archaeologists find fossils, Mayan relics in giant underwater cave in Mexico

MEXICO CITY, Mexico (AFP) — Archaeologists who have been exploring the world’s largest underwater cave — recently discovered in Mexico — presented their findings Monday, including fossils of giant sloths and an elaborate shrine to the Mayan god of commerce. Researchers discovered last month that two large networks of underwater caves in Mexico’s Yucatan peninsula, the Sac Actun and Dos Ojos networks, are in fact connected, forming the largest such structure on Earth. Diving with […]

Artificial intelligence poses questions for nature of war: Mattis

WASHINGTON, United States (AFP) — Artificial intelligence and its impact on weapons of the future has made US Defense Secretary Jim Mattis doubt his own theories on warfare. A question on the subject prompted the retired Marine general to give an impromptu seminar on his theory of war Saturday to reporters returning with him from a week-long tour of Europe. Recalling his own writings, he differentiated between the essential nature of war, which is unchanging […]

Blockchain revolution comes to world of humanitarian aid

by Juliette Michel © Agence France-Presse NEW YORK, United States (AFP) — Blockchain, the technology behind the cryptocurrency bitcoin, is taking root in a sector far from finance: the world of humanitarian aid. By offering refugees a virtual identity, reassuring donors that their money is being well spent, or rushing funds where they are needed most, aid charities are experimenting with the technology in the hopes that it can improve their work. “We are at the very […]

Light pollution threatens Chile’s dark skies

by Miguel SANCHEZ Agence France-Presse PARANAL, Chile (AFP) – It seems nothing can escape the inexorable spread of light pollution — not even the giant telescopes probing the heavens above northern Chile, a region whose pristine dark skies, long considered a paradise for astronomers, are under increasing threat. The Atacama desert, 1,200 kilometers (750 miles) north of the capital Santiago, provides ideal conditions where astronomers study the stars in darkness so profound they appear like diamonds on […]
