Recently quantum computers started to work with more than just the zeros and ones we know from classical computers. Now a team demonstrates a way to efficiently create entanglement of such high-dimensional systems to enable more powerful calculations.

Imagine the view from the western coastline of southern Africa during the Last Glacial Maximum (LGM) over twenty thousand years ago: in the distance you would see at least fifteen large islands -- the largest 300 square kilometers in area -- swarming with hundreds of millions of marine birds and penguin colonies.

There are high expectations that quantum computers may deliver revolutionary new possibilities for simulating chemical processes. This could have a major impact on everything from the development of new pharmaceuticals to new materials. Researchers have now used a quantum computer to undertake calculations within a real-life case in chemistry.

In the future, communications networks and computers will use information stored in objects governed by the microscopic laws of quantum mechanics. This capability can potentially underpin communication with greatly enhanced security and computers with unprecedented power. A vital component of these technologies will be memory devices capable of storing quantum information to be retrieved at will.

We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of x-rays. Researchers used micro-CT scans to peer inside the fossilized stomach remains of a small marine reptile -- a plesiosaur nicknamed 'Eric' after a song from the comedy group Monty Python -- to determine what the creature ate in the lead up to its death.

In the quantum world particles can instantaneously know about each other's state, even when separated by large distances. This is known as nonlocality. Now, A research group has produced some interesting findings on the Hardy nonlocality that have important ramifications for understanding quantum mechanics and its potential applications in communications.

Solids can be melted by heating, but in the quantum world it can also be the other way around: An experimental team has shown how a quantum liquid forms supersolid structures by heating. The scientists obtained a first phase diagram for a supersolid at finite temperature.

Scientists have discovered extensive, ancient deep-sea coral reefs within the Galápagos Marine Reserve (GMR) -- the first of their kind ever to be documented inside the marine protected area (MPA) since it was established in 1998. The first reef observed was found at 400-600m (1,310-1,970 feet) depth at the summit of a previously unmapped seamount in the central part of the archipelago and supports a breathtaking mix of deep marine life.

The nano-scale electronic parts in devices like smartphones are solid, static objects that once designed and built cannot transform into anything else. But physicists have reported the discovery of nano-scale devices that can transform into many different shapes and sizes even though they exist in solid states.

The high seas have been colonized by a surprising number of coastal marine invertebrate species, which can now survive and reproduce in the open ocean, contributing strongly to the floating community composition. Researchers found coastal species, representing diverse taxonomic groups and life history traits, in the eastern North Pacific Subtropical Gyre on over 70 percent of the plastic debris they examined. Further, the debris carried more coastal species than open ocean species.

For several years, a team of researchers used underwater microphones to listen for seals at the edge of the Antarctic. Their initial findings indicate that sea-ice retreat has had significant effects on the animals' behavior: when the ice disappears, areas normally full of vocalizations become very quiet.

Studying mass extinction events from the past can build our understanding of how ecosystems and the communities of organisms within them respond. Researchers are looking to the Late Devonian mass extinction which happened around 370 million years ago to better understand how communities of organisms respond in times of great upheaval.

The flow of matter, from macroscopic water currents to the microscopic flow of electric charge, underpins much of the infrastructure of modern times. In the search for breakthroughs in energy efficiency, data storage capacity, and processing speed, scientists search for ways in which to control the flow of quantum aspects of matter such as the 'spin' of an electron -- its magnetic moment -- or its 'valley state', a novel quantum aspect of matter found in many two dimensional materials. A team of researchers has recently discovered a route to induce and control the flow of spin and valley currents at ultrafast times with specially designed laser pulses, offering a new perspective on the ongoing search for the next generation of information technologies.

The amount of dissolved oxygen in a river is a matter of life or death for the plants and animals living within it, but this oxygen concentration varies drastically from one river to another, depending on their unique temperature, light and flow. To better understand which factor has the greatest impact on the concentration of dissolved oxygen, researchers used a deep learning model to analyze data from hundreds of rivers across the United States.
