Measuring between 3 to 3.5 meters, 16 million years old: Paleontologists have announced the discovery of a new species of freshwater dolphin in the Peruvian Amazon region. Surprisingly, its closest living relatives can be found in the river dolphins of South Asia.

Quantum computers promise to tackle some of the most challenging problems facing humanity today. While much attention has been directed towards the computation of quantum information, the transduction of information within quantum networks is equally crucial in materializing the potential of this new technology. Addressing this need, a research team is now introducing a new approach for transducing quantum information: the team has manipulated quantum bits, so called qubits, by harnessing the magnetic field of magnons -- wave-like excitations in a magnetic material -- that occur within microscopic magnetic disks.

Scientists found that farmed salmon production leads to an overall loss of essential dietary nutrients. They say that eating more wild 'feed' species directly could benefit our health while reducing aquaculture demand for finite marine resources.

When plastic ends up in the ocean, it gradually weathers and disintegrates into small particles. If marine animals ingest these particles, their health can be severely affected. Large accumulations of plastic can therefore disrupt the biological balance of marine ecosystems. But which areas are particularly affected?

Researchers have made very fast and very precise images of excitons -- in fact, accurate to one quadrillionth of a second and one billionth of a meter. This understanding is essential for developing more efficient materials with organic semiconductors.

When climate scientists look to the future to determine what the effects of climate change may be, they use computer models to simulate potential outcomes such as how precipitation will change in a warming world. Some scientists are also looking at something a little more tangible: coral.

A new study has found a decline in the abundance of marine fish species that move rapidly toward the poles to escape rising sea temperatures. The researchers explain that many animal species are currently moving toward cooler regions as a result of global warming, but the velocity of such range shifts varies greatly for different species. Examining thousands of populations from almost 150 fish species, the researchers show that contrary to the prevailing view, rapid range shifts coincide with widescale population declines.

Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.

Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists about life on Earth and potential life on other planets.

Researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population. Based on available evidence, the researchers posit that the 49 orcas could belong to a subpopulation of transient killer whales or a unique oceanic population found in waters off the coast of California and Oregon.

A new study provides groundbreaking findings that offer insights on the migration and foraging patterns of leatherback sea turtles along the Northwest Atlantic shelf.

Restored salmon habitat should resemble financial portfolios, offering fish diverse options for feeding and survival so that they can weather various conditions as the climate changes, a new study shows.

Researchers have created a new material that uses 'redox gating' to control the movement of electrons in and out of a semiconducting material.

Biologists announce the discovery of numerous species of roundworm in the highly saline waters of Great Salt Lake, the vast terminal lake in northwestern Utah that supports millions of migratory birds. Previously, brine shrimp and brine flies were the only known multicellular animals living in the water column. The scientists found nematodes, belonging to a family known for inhabiting extreme environments, in the lake's microbialites, reef-like structures covering about a fifth of the lakebed.

Marine heat waves in the northeast Pacific Ocean create ongoing and complex disruptions of the ocean food web that may benefit some species but threaten the future of many others, a new study has shown.

To advance neuromorphic computing, some researchers are looking at analog improvements -- advancing not just software, but hardware too. Research shows a promising new way to store and transmit information using disordered superconducting loops.

Through steady advances in the development of quantum computers and their ever-improving performance, it will be possible in the future to crack our current encryption processes. To address this challenge, researchers are developing encryption methods that will apply physical laws to prevent the interception of messages. To safeguard communications over long distances, the QUICK space mission will deploy satellites.

Emperor penguin populations have been exceedingly difficult to monitor because of their remote locations, and because individuals form breeding colonies on seasonal sea ice fastened to land (known as fast ice) during the dark and cold Antarctic winter. New research that incorporates very high-resolution satellite imagery with field-based validation surveys and long-term data has provided the first multi-year time series that documents emperor penguin global population trends.

Healthy coral reefs have rich soundscapes, full of the croaks, purrs, and grunts of various fishes and the crackling of snapping shrimp. Larval coral uses these sounds as cues to identify the best places to settle and grow. The authors found that sound could potentially be a vital tool in the effort to restore coral reefs. Broadcasting the sounds of a healthy reef to a reef that is degraded encourages coral larvae to settle there. This indicates that it's possible that 'acoustic enrichment' can be a key intervention to support imperiled reefs.

A large find of dinosaur tracks and fossilized plants and tree stumps in far northwestern Alaska provides new information about the climate and movement of animals near the time when they began traveling between the Asian and North American continents roughly 100 million years ago.
