by Joshua Howat Berger Agence France-Presse RIO DE JANEIRO, Brazil (AFP) — There are few places on Earth as isolated as Trindade island, a volcanic outcrop a three- to four-day boat trip off the coast of Brazil. So geologist Fernanda Avelar Santos was startled to find an unsettling sign of human impact on the otherwise untouched landscape: rocks formed from the glut of plastic pollution floating in the ocean. Santos first found the plastic rocks […]

Black diamond, largest ever cut, sells for £3.2 million
LONDON, United Kingdom (AFP) – “The Enigma”, the world’s largest known cut diamond at 555 carats, went under the hammer in London on Wednesday for £3.16 million ($4.3 million, 3.8 million euros) having recently gone on display for the first time. The rare black, or carbanado, diamond is believed to have been created when a meteorite or an asteroid hit Earth more than 2.6 billion years ago. The 555.55 carat, 55-faced diamond reached £3.16 million, excluding the […]
Bering Sea ice at lowest levels in 5,500 years: study
WASHINGTON D.C., United States (AFP) — Winter ice in the Bering Sea, in the northern Pacific Ocean between Alaska and Russia, is at its lowest levels for 5,500 years, according to a study released Wednesday. Researchers analyzed vegetation that accumulated on the uninhabited island of St Matthew over the last five millennia. They looked at variations in peat layers of oxygen atoms called isotopes 16 and 18, whose proportions over time correlate with atmospheric and oceanic […]
Before Mars landing, a nail-biting ‘six and a half minutes of terror’
by Kerry SHERIDAN Agence France Presse TAMPA, United States (AFP) — A spacecraft that cost nearly a billion dollars is on course to make a perilous landing Monday on Mars, if it can survive a high-speed approach and the scorching heat of entering the Red Planet’s atmosphere, a process NASA has nicknamed “six and a half minutes of terror.” “There is very little room for things to go wrong,” said Rob Grover, head of […]
Huge quake edges New Zealand islands closer together
WELLINGTON, New Zealand (AFP) — A destructive earthquake that struck New Zealand two years ago has left its two main islands edging towards each other, and one city sinking, according to scientists. But the margins are minimal with the gap between the North and South islands narrowing a mere 35 centimetres (13 and a half inches), while Nelson at the top of the South Island has sunk by up to 20 millimetres. The magnitude […]
Indonesia: the world’s volcanic hotspot
JAKARTA, Indonesia (AFP) — Indonesia, where more than 40,000 people have been evacuated over fears of an imminent volcanic eruption at Mount Agung on Bali, is the world’s most volcanic area. The Southeast Asian archipelago of more than 17,000 islands and islets — and nearly 130 active volcanoes — is situated on the Pacific “Ring of Fire”, a vast zone of geological instability where the collision of tectonic plates causes frequent quakes and major volcanic […]
Indonesia volcano continues exhibiting signs of eruption: geologist
BALI, Indonesia (Reuters) — The chance of an eruption remained high as the Mount Agung volcano in Indonesia’s tourist island of Bali continues exhibiting signs of unrest, a geologist said on Friday. Gede Suantika, a geologist at the Mount Agung Observation Post, said the volcano has maintained a menacingly high level of seismic activity, with tremors shaking the mountain daily since volcanic activity began increasing on Sept. 18. “The condition of this volcano is still […]
