Abundant and diverse ecosystem found in area targeted for deep-sea mining

An <i>Amperima holothurian</i> or sea cucumber seen on a bed of polymetallic nodules in the eastern Clarion-Clipperton Zone. Several corals, a sponge and a brittle star can also be seen in the image.In a study published in Scientific Reports, scientists discovered impressive abundance and diversity among the creatures living on the seafloor in the Clarion-Clipperton Zone (CCZ)--an area in the equatorial Pacific...

Breakthrough solar cell captures CO2 and sunlight, produces burnable fuel

Simulated sunlight powers a solar cell that converts atmospheric carbon dioxide directly into syngas.Researchers at the University of Illinois at Chicago have engineered a potentially game-changing solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only...

Vortex laser offers hope for Moore's Law

The image above shows vortex laser on a chip. Because the laser beam travels in a corkscrew pattern, encoding information into different vortex twists, it's able to carry 10 times or more the amount of information than that of conventional lasers.Like a whirlpool, a new light-based communication tool carries data in a swift, circular motion.

Evolution drives how fast plants could migrate with climate change: UBC study

Seeds are ready to disperse from the <em>Arabidopsis thaliana</em> plant in a greenhouse.New research from the University of British Columbia suggests evolution is a driving mechanism behind plant migration, and that scientists may be underestimating how quickly species can move.

New fossil evidence supports theory that first mass extinction engineered by early animals

The disc-like fossils shown here are the preserved remains of holdfast structures used by the Ediacaran species <I>Aspidella</I> that went extinct about a million years after these individuals died and were preserved.Newly discovered fossil evidence from Namibia strengthens the proposition that the world's first mass extinction was caused by "ecosystem engineers" - newly evolved biological organisms that altered the environment so...

Researchers pinpoint abrupt onset of modern day Indian Ocean monsoon system

Anna Ling, a Ph.D. candidate in UM Rosenstiel School's Department of Marine Geosciences, catalogs core samples aboard the research vessel JOIDES Resolution. Ling was part of an international team of 31 scientists from 15 countries that sailed on an eight-week International Ocean Discovery Program (IODP) Expedition 359 to the Maldives.A new study by an international team of scientists reveals the exact timing of the onset of the modern monsoon pattern in the Maldives 12.9 million years ago, and its...

Knots in chaotic waves

Tangled quantum vortices. Each vortex line is shaded in a different color, and may be knotted or linked with the others.New research, using computer models of wave chaos, has shown that three-dimensional tangled vortex filaments can in fact be knotted in many highly complex ways.

Chorus of black holes radiates X-rays

<p>The blue dots in this field of galaxies, known as the COSMOS field, show galaxies that contain supermassive black holes emitting high-energy X-rays. They were detected by NASA's Nuclear Spectroscopic Array, or NuSTAR, which spotted 32 such black holes in this field and has observed hundreds across the whole sky so far.

<p>The other colored dots are galaxies that host black holes emitting lower-energy X-rays, and were spotted by NASA's Chandra X-ray Observatory. Chandra data show X-rays with energies between 0.5 to 7 kiloelectron volts, while NuSTAR data show X-rays between 8 to 24 kiloelectron volts.Supermassive black holes do not give off any of their own light, hence the word "black" in their name. However, many black holes pull in, or accrete, surrounding material, and...

Jupiter's great red spot heats planet's upper atmosphere

Turbulent atmospheric flows above the storm produce both gravity waves and acoustic waves. Gravity waves are much like how a guitar string moves when plucked, while acoustic waves are compressions of the air (sound waves!). Heating in the upper atmosphere 500 miles above the storm is thought to be caused by a combination of these two wave types 'crashing' like ocean waves on a beach.Researchers from Boston University's (BU) Center for Space Physics report today in Nature that Jupiter's Great Red Spot may provide the mysterious source of energy required to heat the planet's...
