Predatory fish use rapid color changes to coordinate attacks      (via sciencedaily.com)     Original source 

Striped marlin are some of the fastest animals on the planet and one of the ocean's top predators. When hunting in groups, individual marlin will take turns attacking schools of prey fish one at a time. Now a new study helps to explain how they might coordinate this turn-taking style of attack on their prey to avoid injuring each other. The key, according to the new work, is rapid color changes.

Lab-spun sponges form perfect scaffolds for growing skin cells to heal wounds      (via sciencedaily.com)     Original source 

A new technique for electro-spinning sponges has allowed scientists to directly produce 3D scaffolds -- on which skin grafts could be grown from the patient's own skin.

Researchers harness 2D magnetic materials for energy-efficient computing      (via sciencedaily.com)     Original source 

Researchers used ultrathin van der Waals materials to create an electron magnet that can be switched at room temperature. This type of magnet could be used to build magnetic processors or memories that would consume far less energy than traditional devices made from silicon.

Scientists can tell where a mouse is looking and located based on its neural activity      (via sciencedaily.com)     Original source 

Researchers have paired a deep learning model with experimental data to 'decode' mouse neural activity. Using the method, they can accurately determine where a mouse is located within an open environment and which direction it is facing, just by looking at its neural firing patterns. Being able to decode neural activity could provide insight into the function and behavior of individual neurons or even entire brain regions.

Method identified to double computer processing speeds      (via sciencedaily.com)     Original source 

Scientists introduce what they call 'simultaneous and heterogeneous multithreading' or SHMT. This system doubles computer processing speeds with existing hardware by simultaneously using graphics processing units (GPUs), hardware accelerators for artificial intelligence (AI) and machine learning (ML), or digital signal processing units to process information.

High resolution techniques reveal clues in 3.5 billion-year-old biomass      (via sciencedaily.com)     Original source 

To learn about the first organisms on our planet, researchers have to analyze the rocks of the early Earth. These can only be found in a few places on the surface of the Earth. The Pilbara Craton in Western Australia is one of these rare sites: there are rocks there that are around 3.5 billion years old containing traces of the microorganisms that lived at that time. A research team has now found new clues about the formation and composition of this ancient biomass, providing insights into the earliest ecosystems on Earth.

An awkward family reunion: Sea monsters are our cousins      (via sciencedaily.com)     Original source 

The sea lamprey, a 500-million-year-old animal with a sharp-toothed suction cup for a mouth, is the thing of nightmares. A new study discovered that the hindbrain -- the part of the brain controlling vital functions like blood pressure and heart rate -- of both sea lampreys and humans is built using an extraordinarily similar molecular and genetic toolkit.

New water batteries stay cool under pressure      (via sciencedaily.com)     Original source 

A global team of researchers has invented recyclable 'water batteries' that won't catch fire or explode. The team use water to replace organic electrolytes -- which enable the flow of electric current between the positive and negative terminals -- meaning their batteries can't start a fire or blow up -- unlike their lithium-ion counterparts.
