Researchers develop soft robot that shifts from land to sea with ease      (via sciencedaily.com) 

Most animals can quickly transition from walking to jumping to crawling to swimming if needed without reconfiguring or making major adjustments. Most robots cannot. But researchers have now created soft robots that can seamlessly shift from walking to swimming, for example, or crawling to rolling using a bistable actuator made of 3D-printed soft rubber containing shape-memory alloy springs that react to electrical currents by contracting, which causes the actuator to bend. The team used this bistable motion to change the actuator or robot's shape. Once the robot changes shape, it is stable until another electrical charge morphs it back to its previous configuration.

Are piezoelectrics good for generating electricity? Perhaps, but we must decide how to evaluate them      (via sciencedaily.com) 

A 'best practice' protocol for researchers developing piezoelectric materials has been developed by scientists. The protocol was developed by an international team led by physicists in response to findings that experimental reports lack consistency. The researchers made the shocking discovery that nine out of 10 scientific papers miss experimental information that is crucial to ensure the reproducibility of the reported work.

Assessing the potential risks of ocean-based climate intervention technologies on deep-sea ecosystems      (via sciencedaily.com) 

An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.

Electrocatalysis under the atomic force microscope      (via sciencedaily.com) 

A further development in atomic force microscopy now makes it possible to simultaneously image the height profile of nanometer-fine structures as well as the electric current and the frictional force at solid-liquid interfaces. A team has succeeded in analyzing electrocatalytically active materials and gaining insights that will help optimize catalysts. The method is also potentially suitable for studying processes on battery electrodes, in photocatalysis or on active biomaterials.

Paleontologists flip the script on anemone fossils      (via sciencedaily.com) 

Billions of sea anemones adorn the bottom of the Earth's oceans -- yet they are among the rarest of fossils because their squishy bodies lack easily fossilized hard parts. Now a team of paleontologists has discovered that countless sea anemone fossils have been hiding in plain sight for nearly 50 years. It turns out that fossils long-interpreted as jellyfish were anemones. To do so, a team of scientists has simply turned the ancient animals upside down.

New 'camera' with shutter speed of 1 trillionth of a second sees through dynamic disorder of atoms      (via sciencedaily.com) 

Researchers have developed a new 'camera' that sees the local disorder in materials. Its key feature is a variable shutter speed: because the disordered atomic clusters are moving, when the team used a slow shutter, the dynamic disorder blurred out, but when they used a fast shutter, they could see it. The method uses neutrons to measure atomic positions with a shutter speed of around one picosecond, a trillion times faster than normal camera shutters.

Does current shellfish anti-predator gear curb 'crunching' rays?      (via sciencedaily.com) 

It's not just humans who enjoy eating shellfish, so do marine rays. They like to 'crunch' on clams, which can sometimes take a big bite out of clammers' profits. Using aerial and underwater videos, researchers assessed the ability of the whitespotted eagle ray to interact with clams housed within a variety anti-predator materials. Whitespotted eagle rays have strong jaws, plate-like teeth and nimble pectoral fins, which make them formidable and highly maneuverable predators of clams.

Controlling electric double layer dynamics for next generation all-solid-state batteries      (via sciencedaily.com) 

Development of all-solid-state batteries is crucial to achieve carbon neutrality. However, their high surface resistance causes these batteries to have low output, limiting their applications. To this end, researchers have employed a novel technique to investigate and modulate electric double layer dynamics at the solid/solid electrolyte interface. The researchers demonstrate unprecedented control of response speed by over two orders of magnitude, a major steppingstone towards realization of commercial all-solid-state batteries.
