Scientists have created a comprehensive 'roadmap' to guide global efforts to convert waste energy into clean power.

Researchers have demonstrated a caterpillar-like soft robot that can move forward, backward and dip under narrow spaces. The caterpillar-bot's movement is driven by a novel pattern of silver nanowires that use heat to control the way the robot bends, allowing users to steer the robot in either direction.

By combining lab experiments and mathematical modelling, researchers have found a way to predict the movement of species that could guide conservation efforts to reconnect fragmented habitats.

An unusually severe form of toxoplasmosis killed four sea otters and could pose a threat to other marine wildlife and humans, finds a new study.

An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare elements and it is incombustible. For large energy storage systems, this could be an optimal solution.

New method to study the movement, behaviour, and environmental context of group-living animals using drones and computer vision.

Moderate levels of artificial light at night -- like the fixture illuminating your backyard -- bring more caterpillar predators and reduce the chance that these lepidoptera larvae grow up to become moths and serve as food for larger prey.

New research introduces metamaterial concrete for the development of smart civil infrastructure systems. Researchers present a new concept for lightweight and mechanically-tunable concrete systems that have integrated energy harvesting and sensing functionality.

Plants use photosynthesis to harvest energy from sunlight. Now researchers have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.

Scientists investigating a compound called 'Y-ball' -- which belongs to a mysterious class of 'strange metals' viewed as centrally important to next-generation quantum materials -- have found new ways to probe and understand its behavior.

Research shows promise for developing high-energy-density rechargeable lithium-metal batteries and addressing the electrochemical oxidation instability of ether-based electrolytes.

Fewer parasites in U.S. waters might be seen by many as a good thing, but a biologist says the trend signals potential danger for fish and other wildlife.

Researchers confirmed what was already known: jellyfish eat bigger prey as they grow, which means they also occupy a higher position in the food web as they grow. They also found that some of the concentrations of 'healthy fats,' increase as jellyfish grow. These changes might be influenced by their diet, and as they feed on bigger prey with higher levels of fatty acids, the jellyfish accumulate more of these fatty acids.

Cultivation and growth of grapevines have strongly influenced European civilizations, but where the grapevine comes from and how it has spread across the globe has been highly disputed so far. In an extensive genome project, researchers have determined its origin and evolution from the wild vine to today's cultivar by analyzing thousands of vine genomes collected along the Silk Road from China to Western Europe.

Sunlight can be used to produce green hydrogen directly from water in photoelectrochemical (PEC) cells. So far, most systems based on this 'direct approach' have not been energetically competitive. However, the balance changes as soon as some of the hydrogen in such PEC cells is used in-situ for a catalytic hydrogenation reaction, resulting in the co-production of chemicals used in the chemical and pharmaceutical industries. The energy payback time of photoelectrochemical 'green' hydrogen production can be reduced dramatically, the study shows.

A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.

The small size and isolation of the endangered population of Southern Resident killer whales in the Pacific Northwest have led to high levels of inbreeding. This inbreeding has contributed to their decline, which has continued as surrounding killer whale populations expand, according to new research.

Researchers have developed a breakthrough process for making spintronic devices that has the potential to create semiconductors chips with unmatched energy efficiency and storage for use in computers, smartphones, and many other electronics.

Parasitic infections in salmonid fish can increase or decrease their vulnerability to angling, depending on their body condition.

Hummingbirds use the hibernation-like state of torpor in varying ways, depending on their physical condition and what is happening in their environment, according to new research.
