Researchers create realistic virtual rodent      (via sciencedaily.com)     Original source 

To help probe the mystery of how brains control movement, scientists have created a virtual rat with an artificial brain that can move around just like a real rodent. The researchers found that activations in the virtual control network accurately predicted neural activity measured from the brains of real rats producing the same behaviors.

Trash-sorting robot mimics complex human sense of touch      (via sciencedaily.com)     Original source 

Researchers are breaking through the difficulties of robotic recognition of various common, yet complex, items. Their layered sensor is equipped with material detection at the surface and pressure sensitivity at the bottom, with a porous middle layer sensitive to thermal changes. An efficient cascade classification algorithm rules out object types in order, from easy to hard, starting with simple categories like empty cartons before moving on to orange peels or scraps of cloth.

Scientists 'read' the messages in chemical clues left by coral reef inhabitants      (via sciencedaily.com)     Original source 

What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. But in underwater environments, invisible compounds create a complex 'soup' that is hard for scientists to decipher. Now, researchers have demonstrated a way to extract and identify these indicator compounds in seawater. They found metabolites previously undetected on reefs, including three that may represent different reef organisms.

A new study reveals that marine cyanobacteria communicate      (via sciencedaily.com)     Original source 

A breakthrough study changes the way we understand cyanobacteria, which are essential for the sustenance of life. The study shows that these organisms do not operate in isolation, but rather physically interact through membrane-nanotubes, which function as exchange bridges between cells.

Liquid metal-based electronic logic device that mimics intelligent prey-capture mechanism of Venus flytrap      (via sciencedaily.com)     Original source 

A research team has developed a liquid metal-based electronic logic device that mimics the intelligent prey-capture mechanism of Venus flytraps. Exhibiting memory and counting properties, the device can intelligently respond to various stimulus sequences without the need for additional electronic components. The intelligent strategies and logic mechanisms in the device provide a fresh perspective on understanding 'intelligence' in nature and offer inspiration for the development of 'embodied intelligence'.

Scientists question effectiveness of nature-based CO2 removal using the ocean      (via sciencedaily.com)     Original source 

Limited understanding of basic ocean processes is hindering progress in marine carbon dioxide removal, with the on-going commercialization of some approaches 'premature and misguided'. Scientists now review the climatic effectiveness of four 'nature-based' techniques using marine biological processes. These involve shellfish cultivation, seaweed farming, coastal blue carbon -- using the restoration of seagrass, saltmarsh and mangrove forests -- and increasing whale populations through 're-wilding'.

'Open gates' in warming Arctic are expanding salmon range      (via sciencedaily.com)     Original source 

New research has connected warming ocean temperatures to higher Pacific salmon abundance in the Canadian Arctic, an indicator that climate change is creating new corridors for the fish to expand their range. Salmon haven't historically been seen in large numbers in the Arctic Ocean and its watersheds, but in recent years incidental catches by subsistence fishermen have occasionally surged. Researchers working together with communities in the western Canadian Arctic, connected those salmon booms with a sequence of warm, ice-free conditions in the Arctic Ocean north of Alaska.

Early summer fishing can have an evolutionary impact, resulting in smaller salmon      (via sciencedaily.com)     Original source 

A new genetic study found that heavy fishing in the early part of the fishing season may result in younger and smaller Atlantic salmon. This information can help to conserve large fish essential for the diversity and viability of salmon populations.

Small, but smart: How symbiotic bacteria adapt to big environmental changes      (via sciencedaily.com)     Original source 

Lucinid clams, inconspicuous inhabitants of the seafloor and one of the most diverse group of animals in the ocean, rely on symbiotic bacteria for their survival. Researchers now reveal the evolutionary journey of these tiny tenants. Faced with a drastically changing environment following the closure of the Isthmus of Panama, they acquired new metabolic skills to enable their own survival. Understanding the adaptive strategies of bacteria provides insight into their potential responses to challenging environmental changes, such as those caused by human activities.
