    JAKARTA Ė At least 389 climbers, including 333 foreigners, might be still on a volcano near the Indonesian resort island of Bali that had erupted Tuesday afternoon, government officials said. Mount Barujari on Lombok Island, which is located east of Bali, erupted at 3 p.m. local time Tuesday, spewing volcanic ash as high as 2 km into the air. The eruption forced the Center for Volcanology and Geological Hazard Mitigation to raise the status of the volcano, which is located inside the caldera of bigger Mount Rinjani, to Level 2. Level 4 is the highest alert. The volcanology agency also...

    As scientists continue finding evidence for life in the ocean more than 3 billion years ago, those ancient fossils pose a paradox. Organisms, including the single-celled bacteria living in the ocean at that early date, need a steady supply of phosphorus, but "it's very hard to account for this phosphorus unless it is eroding from the continents," says Aaron Satkoski, a scientist in the geoscience department at the University of Wisconsin-Madison. "So that makes it really hard to explain the fossils we see at this early era." Satkoski, who is first author of a new report on ocean chemistry from...

    10 Population Y The Americas were the final frontier for human expansion. Most believe they were populated 15,000 years ago in one wave via the Bering land bridge. However, recent findings suggest a different story. Geneticists recently discovered DNA that closely resembles that of modern-day Australian Aboriginals and indigenous Papua New Guineans in the most unlikely of places: Amazonia. Experts have named this new founding group ďPopulation Y.Ē These colonizers did not arrive via boat. They came in a separate wave across the Bering Strait. Their unique genetic signatures were similar but not identical to modern Austronesiansósuggesting Population Y intermingled...

    Astronomers using NASA's Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes. The observation increases the possibility that missions to Europa may be able to sample Europaís ocean without having to drill through miles of ice. ďEuropaís ocean is considered to be one of the most promising places that could potentially harbor life in the solar system,Ē said Geoff Yoder, acting associate administrator for NASAís Science Mission Directorate in Washington. ďThese plumes, if...

    It has long puzzled scientists why, after 3 billion years of nothing more complex than algae, complex animals suddenly started to appear on Earth. Now, a team of researchers has put forward some of the strongest evidence yet to support the hypothesis that high levels of oxygen in the oceans were crucial for the emergence of skeletal animals 550 million years ago. The new study is the first to distinguish between bodies of water with low and high levels of oxygen. It shows that poorly oxygenated waters did not support the complex life that evolved immediately prior to the Cambrian...

    There's increasing evidence to show that trees are able to communicate with each other. More than that, trees can learn. The main reason humans cannot perceive how clever and complex they are is because we exist in such short time scales by comparison. There's a tree in Sweden for instance, a spruce, that is more than 9,500 years old. That's 115 times longer than the average human lifespan.

Sakurajima is one of Japan's most active volcanoes with small, localised eruptions nearly every day, but the history of the volcano is even more ferocious. In 1914, a large explosive eruption killed 58 people and caused widespread flooding in the adjacent city of Kagoshima as the ground subsided due to the withdrawal of magma from the subsurface.

    Microsoft researchers have teamed up with physicists from the University of California, Santa Barbara, to show how time crystals might be possible. First proposed by Nobel-prize winning theoretical physicist Frank Wilczek, time crystals are hypothetical systems that spontaneously break time-translational symmetry (TTS) Ė a fundamental symmetry in physics. In plain language, they exhibit tiny movements without using energy. Crystals have a rigid arrangement of atoms that break translational symmetry. Their structure is not symmetrical in space, unlike a sphere, which looks the same from all directions. Time crystals break the symmetry of space and time. Wilczek considered a group of...

    A two-hour launch window opens Thursday at 7:05 p.m. for the Origins Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-REx) mission aboard a United Launch Alliance (ULA) Atlas V-411 rocket. Over the next two years, OSIRIS-REx will travel to the 1,650-foot-wide near-Earth asteroid 101955 Bennu. The spacecraft will then spend two years studying the asteroid and collecting a pristine surface sample for return to Earth in September 2023, the first U.S. mission to do so and the largest sample of an extraterrestrial body since the Apollo missions.
