Marine heatwaves devastate red gorgonians in the Medes Islands      (via sciencedaily.com)     Original source 

The increase in the frequency and intensity of marine heatwaves in recent decades is one of the effects of global climate change. A study shows that the extreme heatwave of 2022 caused an 'unprecedented' increase in mortality of the red gorgonian Paramuricea clavata, affecting 70% of the colonies located in the Montgr Natural Park, the Medes Islands and the Baix Ter. According to the researchers, these results are 'alarming and threaten the viability' of this species of great value for the biodiversity of benthic ecosystems, since it is considered to be an inhabitant-forming species.

How do you know where a fish goes?      (via sciencedaily.com)     Original source 

An acoustic transmitter -- or tag -- emits unique signals or 'pings' when scientists want to study the long-distance movement of marine animals. However, this method has limitations. Using a movement model, researchers reconstructed animal tracks and leveraged an iterative process to measure the accuracy and precision of these reconstructions from acoustic telemetry data. Results demonstrate how researchers can apply these techniques and measure the accuracy and precision of the methods to their study sites.

People feel more connected to 'tweezer-like' bionic tools that don't resemble human hands      (via sciencedaily.com)     Original source 

Some say the next step in human evolution will be the integration of technology with flesh. Now, researchers have used virtual reality to test whether humans can feel embodiment -- the sense that something is part of one's body -- toward prosthetic 'hands' that resemble a pair of tweezers. They report that participants felt an equal degree of embodiment for the tweezer-hands and were also faster and more accurate in completing motor tasks in virtual reality than when they were equipped with a virtual human hand.

Tracing the evolution of ferns' surprisingly sweet defense strategy      (via sciencedaily.com)     Original source 

Plants and the animals that eat them have evolved together in fascinating ways, creating a dynamic interplay of survival strategies. Many plants have developed physical and chemical defenses to fend off herbivores. A well-known strategy in flowering plants is to produce nectar to attract 'ant bodyguards.' Recent research explores the evolution of this same defense strategy in ferns.
